Overshoe socks having band type peeling prevention means {A nude socks having preventing come off device of band type}

The present invention relates to an overshoe-type sock having a band-type peeling prevention means, and in detail, in an overshoe in which a space for accommodating a foot is formed by sewing a bottom part, an instep part, and a side part, the number of feet among the inner surface of the instep part and the side part It is provided in the form of a band part attached to the surface in contact with the band part and the side part so as to have a certain width along the tool (entrance), so that it can prevent peeling even after extreme movement after wearing, and can express elasticity and fixation. it's about

The foot is a part of the body that maintains the balance of the human body and absorbs shock by supporting body weight. It is a place where numerous blood vessels and nerves pass. It is desirable to maintain an appropriate temperature for smooth blood circulation. Socks, stockings, or overshoes are used as means for protecting and keeping the feet warm.

Unlike socks or stockings, which have to be worn above the ankle and therefore have to come out of the shoe, overshoe socks have the foot entrance located just above the instep and heel and do not come out of the shoe, so recently they have been used for fashion or dressing up during sports activities or general outings. It is often used for the purpose of preserving individuality.

General overshoes have a bottom part and a side end of the bottom part extending to form an entrance into which the wearer's foot can be inserted, and a side part and a part of the side part forming a space for accommodating all of the wearer's toes and a part of the instep and heel It is formed in and consists of a band portion that prevents the overshoes from flowing down.

However, although these overshoes of the prior art are provided with a band portion, there is a problem in that it is difficult to coolly open the upper opening portion to a large area because it slides off the skin and is easily peeled off.

In addition, attempts have been made to attach non-slip silicone along the rim of the entrance where the foot is inserted, but there was a problem in that the non-slip silicone could not be easily attached because the rim of the entrance was rolled and the shape could not be maintained well.

Here, when the end of the last thread in the knitting process is located at the front part of the foot, the end of the thread is exposed and unraveled, so there is no choice but to make a sewing line, and there is also a problem of having to sew with a separate sewing machine along the sewing line.

In the present invention, when the wearer wears a sock-type overshoe, the surface in direct contact with the wearer's foot is referred to as 'inner surface' and the opposite surface of the inner surface as 'outer surface'.

In addition, when the wearer wears socks-type overshoes, the end closest to the toe in the longitudinal direction is called the 'top' and the far end is called the 'bottom', and the end connecting the top and bottom is called the lateral end referred to as

1 to 4, the present invention is described in more detail, the overshoe socks having a peel-off preventing function according to the present invention are formed in a form that covers some or all of the sole, toe, foot blade, heel, instep, etc. when worn , Specifically, the bottom part 100 having a shape similar to the sole of the foot in close contact with the wearer; An instep portion 200 that is sewn with the upper end of the bottom portion and forms a space accommodating all of the wearer's toes, instep, and a portion of the instep; a side part 300 that is sewn with the side end and lower end of the bottom part and the side end of the instep part to form a space for accommodating a part of a wearer's foot blade and a part of a heel; and a band portion 400 attached to an inner surface of the side portion to impart elasticity.

In the present invention, the bottom part 100 is in contact with the sole of the wearer's foot, and may be connected to the instep part and side part covering the instep, foot blade, toe, etc. by sewing or the like. That is, the bottom portion has a foot-shaped shape so as to completely cover the sole of the foot, and has a structure in which the side end is sewn with another cloth or knitted into one by a circular knitting method to combine with the side portion to accommodate the foot.

Since the bottom part transmits the impact of the ground to the wearer, the fineness of the fiber may be greater than that of the instep part or the side part, or an element capable of buffering action such as pile yarn may be further added.

For example, when weaving or knitting the bottom part, more pile yarn is added and less interlacing with other weft yarns, warp yarns, etc., so that a plurality of loops are formed on the surface so as to protrude. It can have a buffering effect while being unfolded or restored according to the back.

The instep portion 200 may be formed by being connected to each other by sewing or the like to protect the wearer's toes. At this time, in order to increase the protection effect of the toes of the instep part, a seam line is formed by stitching between the instep part and the bottom part, and a reinforcing part 210 may be further provided to contact a part of the seam line with the bottom part of the inner surface. there is.

The reinforcing part 210 prevents fraying or holes from occurring due to friction with the toe, particularly the toenail, by forming a relatively thick thickness of a part of the instep of the instep, especially the part in direct contact with the toe, compared to the side or bottom part. It can prevent and suppress the phenomenon that the toe is exposed to the outside when worn.

To this end, the reinforcing part may be provided to cover the entire upper surface of the toe by extending a certain width along the seam line of the instep and the bottom, as shown in FIG. 4 . In addition, if necessary, after laminating the reinforcing part and the instep part so as to overlap each other, and then sewing the bottom part together, the bonding strength of the reinforcing part, instep part, and bottom part can be further increased and the seam line can be prevented from easily bursting.

The side part 300 is formed by extending the side end of the bottom part and the lower end of the instep part by sewing, etc., and may be formed to cover the instep, toenail, or heel of the wearer.

That is, when the sock-type overshoe is turned over so that the inner surface becomes the outer surface and the outer surface becomes the inner surface as shown in FIG. 4, the bottom part is formed in the shape of a foot to combine the side part and the instep part, so that the sole, toe, and toe are formed. It covers completely and can be formed to cover the top of the foot and part of the heel.

In addition, as the seam line is formed inside the overshoe as described above, it is possible to prevent damage to the aesthetics and at the same time to prevent the seam line from being ruptured or a hole generated by friction with the shoe.

In the present invention, the band portion 400 controls the elasticity of the sock according to the wearer's movement or external force and prevents peeling when worn, and is formed by sewing the instep and side parts of the inner surface of the instep and side parts to each other. It may be attached in the form of a tape having a certain width along the inlet.

That is, the band portion is formed on the instep and the side portion, respectively, as shown in FIGS. 1 to 3, thereby tightening the inlet line leading to the instep, toe blade, heel, etc., and to suppress excessive elongation of the sock due to external force and at the same time as needed. Since it has a characteristic of elongation over a certain amount along the line, rupture or tearing of the seam can be prevented.

In addition, when the band part is formed of silicone, allergies such as redness, itching, blisters, swelling, etc. may occur on the skin depending on the person, but the band part according to the present invention can suppress the occurrence of allergies by minimizing the range of use of silicone. can

The band portion is not limited in width, but is preferably formed within the range of 0.1 to 3 cm. Within the above range, it is possible to prevent the socks from coming off by improving the adhesion between the socks and the user's instep or toenail, and suppress the deterioration of wearing comfort due to excessive adhesion of the band part.

Specifically, when the width of the band part is formed less than the above range, the contact area between the tape and the foot is reduced, so socks are easily peeled off. , the wearing comfort may decrease.

Here, as shown in FIG. 2, the band portion is provided to cover a certain portion of the heel, so that the wearer's skin damage due to friction with the shoe can be suppressed.

In general, in the case of newly purchased shoes, since the heel of the shoe is hard, the heel of the wearer is often scratched. Therefore, when wearing new shoes, in many cases, a pad is attached to the inner surface of the heel of the shoe to reduce heel pain.

However, such a heel pad is typically coated with an adhesive on one side of the pad, and a foreign body sensation may be transmitted when worn, and the adhesive effect decreases with use, causing the pad to roll up.

In the present invention, in order to solve the above problems, the band part is provided to cover the connection part of the foot and the ankle as a whole, and in particular, the width of the part in contact with the heel of the foot is provided to be greater than the width of the part in contact with other parts of the foot, so that it is worn. It can cover a wider area than other parts of the foot.

That is, as shown in FIG. 2, the band portion is formed to have a width larger than that of the other side portion or instep portion formed on the heel, thereby primarily improving adhesion to the heel and increasing resistance to peeling. At the same time, since the band portion is formed by being adhered to the side portion, the thickness is increased compared to other portions of the sock, thereby reducing the possibility of rupture or tearing due to friction. Here, as the band part adheres to the heel, it protects the wearer's heel by buffering the hard heel of the shoe in the same way as the heel pad.

FIG. 3 is a side view of the band portion of FIG. 4 . As shown in FIG. 3 , the band portion may be provided with an arc of a certain size so that a portion formed on the heel completely covers the ankle. Through this, adhesion to the heel and ankle can be improved, resistance to peeling can be increased, and direct friction between the heel and the shoe can be prevented.

In the overshoe-type socks according to the present invention, the yarn constituting the bottom part, the instep part, the band part, or the side part is made of cellulose-based fibers as a base for sweat absorption, but mechanical properties such as low strength and elongation, which are disadvantages of the cellulose-based fibers It is preferable to ply synthetic fibers in the form of one or a plurality of filaments to compensate.

In the present invention, for example, the cellulosic fibers may include general cellulosic fibers such as cotton fibers and hemp fibers, or semi-synthetic fibers such as rayon, and among them, cotton fibers have excellent skin affinity and high It is preferable because it is possible to secure absorbency, soft touch, appropriate strength and elongation, and the like.

In the present invention, the synthetic fiber in the form of a filament is mainly intended to be plied with the cotton fiber in order to secure the mechanical properties of the cotton fiber, especially insufficient strength and elongation, and is easily elongated according to the wearer's movement or external force, and is originally It is preferable to include elastic fibers that can be recovered to shape.

Specifically, the elastic fibers collectively refer to fibers having elasticity and resilience obtained by spinning a specific structure or modified polymer, and the degree of elongation may vary depending on the type of polymer material or fiber used.

Traditional elastic fibers have been commercialized for a long time under the trade names of spandex or elastane, and most of them have a breaking elongation of about 200 to 800%, and fibers that return to their original length almost perfectly when the deformation stress is removed. collectively

Examples of the elastic fibers include polyurethane, polyester-ether, polybutylene terephthalate, polytrimethylene terephthalate, ethylene-olefin copolymer, and polyoxymethylene, which are used alone or in combination of two or more. It is free to buy.

As the elastic fiber, polyurethane may be more preferably used. The polyurethane elastic fibers have various spinning methods, inexpensive raw materials, and have high strength and modulus compared to general natural rubber fibers, and are excellent in change over time and dyeability.

The cotton fiber and the elastic fiber are not limited to the ratio when plying, but the cotton fiber and the elastic fiber are preferably mixed in a weight ratio of 5 to 9: 1 to 5, respectively. Within the above range, the socks can be stretched according to the wearer's movement or external force, so the wearing comfort can be secured, and at the same time, the original purpose of the socks, such as heat retention or sweat absorption, can be expressed.

In addition, when the fibers are plied, the plying ratio of cotton fibers and elastic fibers may be different for each part or other fibers may be additionally added separately from the elastic fibers to reinforce physical properties. Specifically, since bacterial growth may be active in the bottom part due to sweat and moisture, in order to suppress this, an antibacterial material may be further mixed and spun when manufacturing the elastic fiber.

The antibacterial substance is intended to give antibacterial properties against bacteria having a negative charge by imparting a positive charge to the surface of the fiber, and forms positive ions on the surface of the fiber in the presence of moisture or moisture, and the positive ions are electrically charged with negative ions formed on the surface of microbial cells. It works by pulling it down and destroying the cell membrane by attraction.

The antibacterial substance is not limited to the type as long as it does not react with the fiber polymer even at high heat and does not polymerize, but does not add toxicity to the human body. For example, cetylpyridinium chloride, 1,1-hexamethylene bis (5- (4-chlorophenyl) biguanide hydrochloride (1,1-Hexamethylene bis (5- (4 -chlorophenyl) biguanide) hydrochloride), polyhexamethylene biguanide hydrochloride, 1-methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine (1-methyl-2-nitro -3((3-tetrahydrofuryl)methyl) guanidine), polytetramethyleneguanidinium, polyhexamethyleneguanidinium, polyhexamethylene guanidine phosphate, etc. Or two or more may be used in combination.

The antibacterial material is preferably added in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of the polymer resin constituting the elastic fiber. When added below the above range, the above antibacterial effect is not properly expressed, and when added above the above range, the physical properties of elastic fibers may be deteriorated, resulting in deterioration in elasticity or recovery of socks.

Here, the bottom portion can increase mechanical properties by interacting with the elastic fibers separately from the elastic fibers containing the antibacterial material, and to increase antibacterial properties against positively designated bacteria that cannot be removed through the elastic fibers. Polylactic acid fibers may be further included.

The polylactic acid (lactic acid) fiber is a bio-based polymer and is a linear aliphatic polyester. It is a material produced by polymerizing monomers obtained by chemical conversion of lactic acid produced by starch fermentation mainly obtained from corn and potatoes.

Since lactic acid, which is a raw material of the polylactic acid (lactic acid) fiber, has an optically active carbon atom arrangement in its molecule, it has optical isomers of L-lactic acid and D-lactic acid. Furthermore, it exists as poly L-lactic acid (hereinafter referred to as “PLLA”) and poly D-lactic acid (hereinafter referred to as “PDLA”).

In the present invention, crystalline polylactic acid refers to a polylactic acid having a high ratio of L-lactic acid in PLLA and D-lactic acid in PDLA, that is, a case with high optical purity, high crystallinity, and excellent heat resistance and mechanical properties. .

Further, another polylactic acid-based polymer composition of the present invention preferably includes 50 to 90% by weight of the crystalline polylactic acid and 10 to 50% by weight of the amorphous polylactic acid. By having the above composition ratio, the crystalline polylactic acid exhibits impact resistance and heat resistance, and at the same time, flexibility is imparted by the amorphous polylactic acid-based polymer to improve physical properties. In particular, since the content of amorphous polylactic acid is less than that of crystalline polylactic acid, it is possible to secure strength of the fiber itself while exhibiting a certain level of flexibility, and minimize change in shape due to washing or external force.

As the polylactic acid fiber has a carboxyl group or an aldehyde group in its main chain, its surface is negatively charged. Such negative charge can remove positively charged microparticles or bacteria that cannot be filtered from the nonwoven fabric layer or filament having a positive charge on the surface as described above, further enhancing antibacterial properties, and is skin-friendly and hypoallergenic due to the characteristics obtained from starch, etc. .

Preferably, the polylactic acid fibers include 50 to 80% by weight, 10 to 40% by weight, and 5 to 10% by weight of cotton fibers: elastic fibers: polylactic acid fibers, respectively, when combined with cotton fibers and elastic fibers. If it is out of the above range, it is difficult to secure the antimicrobial properties desired in the present invention or it is not preferable because the flexibility of socks is impaired.

In the present invention, the cotton fiber and the elastic fiber are not limited to the plying method. For example, after producing cotton fibers having a certain fineness through a spinning process, the surface of the cotton fibers is plied to have a covering yarn or, conversely, to a structure in which cotton fibers are wrapped around the surface of the elastic fibers of a filament bundle. It can be. Alternatively, socks having bulky properties may be manufactured by intertwining the cotton fibers and the elastic fibers or forming loops with some fibers.

The fineness of the fibers plied as described above is not limited, but is preferably 10 to 200 denier, more preferably 80 to 150 denier. Within this range, sweat absorption is well achieved, and at the same time, mechanical properties for friction, elongation, etc. can be secured.

However, in the case of the band part, unlike other parts constituting the overshoe type socks, it is more closely attached to the skin when worn, and in particular, the band part covering the heel should prevent skin damage due to friction with shoes. In addition, since it is necessary to control the expansion and contraction of the entire sock and prevent peeling, the fiber fineness or composition, weaving or knitting density, etc. should be different from other parts.

Specifically, the band portion preferably has a smaller fiber fineness than other portions when plying, and more specifically, 10 to 30 denier. In the case of fibers, the smaller the fineness, the softer the touch, and since irritation to the skin is reduced, it is good to make the fineness of the fibers as small as possible for the parts that are close to the skin, such as the band part.

In addition, when the fineness of the fiber is reduced as described above, the density of the fabric can be higher than that of other parts. The density of the fabric varies depending on the manufacturing method, but in the case of hosiery, it is generally made of a knitted fabric rather than a weave to secure flexibility. At this time, the density of the fabric can be adjusted by adjusting a gauge.

The gauge indicates the number of needles entering within 1 inch, and depending on the knitting method, a low gauge with 20 or less needles, a high gauge with 26 or more needles, and a middle gauge that is the middle gauge ) can be divided into

The sock according to the present invention may take different densities of the fabric in the same manner as described above according to each part. Specifically, when flexibility and air permeability must also be secured, such as the bottom, instep, and side surfaces, it is formed in a middle gauge or low gauge to relatively lower the density, and in the case of the above-described reinforcement or band portion, it must be in direct contact with the skin, Since pressure or friction is severe compared to other parts, it is desirable to manufacture it with a high gauge to increase the mechanical properties of the fabric.

For example, the bottom part, the instep part, and the side part are preferably 15 to 25 gauge, and the reinforcing part or band part is manufactured with 26 to 35 gauge to increase the density of the knitted fabric, thereby increasing mechanical strength compared to other parts.

In addition, it is preferable that the band part has cotton fibers and elastic fibers in a weight ratio of 5 to 6: 4 to 5, respectively, to increase restoring force and increase adhesion between socks and feet.

The band portion does not limit the bonding method. For example, when bonding the instep and side parts by sewing similarly to the reinforcement part, the end in the longitudinal direction before joining is laminated to match the end forming the entrance among the inner surfaces of the instep and the side part, and then sewing it. You can connect by doing this.

However, in this case, the parts that are not sewn are not completely joined to the instep or side part, so in order to completely join them, an adhesive layer is formed on the surface in contact with the instep or side part of the band part, and after sewing, heat or pressure is applied to join it is desirable

In the present invention, the components constituting the adhesive layer are not limited, but it is preferable to use a hot melt type adhesive. The hot-melt adhesive is a solid material at room temperature using a thermoplastic resin, which is not dissolved or dispersed in a solvent, and only 100% solid content is dissolved and applied by heat, and then cooled and solidified by dissipating heat to the adherend or surroundings. It is an adhesive that exhibits adhesion in a short time through. These adhesives do not require a drying process compared to other solvent-type adhesives or water-dispersion type adhesives, so they have a small working space and a fast adhesion speed.

In the present invention, the hot melt type adhesive is not limited to a type as long as it is commonly used in the art for bonding leather, film, sheet, etc. The material of the hot melt type adhesive usable in the present invention is, for example, any one selected from polyamide hot melt, polyester hot melt, polyurethane hot melt, polyolefin hot melt, polystyrene hot melt, ethylene-acrylic copolymer hot melt and ethylene vinyl acetate hot melt The above polyolefin type resin can use what is a main component.

The melting temperature of the hot-melt adhesive is not limited, but is preferably 150° C. or less in terms of ease of operation and process conditions. In addition, the melt index is preferably 5 to 500 cm 3 / 10 min. Within the above range, sweat and the like can be effectively discharged when worn without reducing the adhesive strength between the band portion and the instep portion or the side portion.

In the present invention, the adhesive layer is not limited in thickness during application, but preferably has a thickness of 0.01 to 0.1 mm so as not to affect flexibility or the like. Here, it is good to have various patterns so as not to decrease the moisture permeability effect by the adhesive layer. At this time, the shape of the pattern is not limited in the present invention, but it is good to have a dot shape to minimize the area covered by the adhesive layer.

In the present invention, the silicone layer 410 is formed on the inner surface of the band part in contact with the heel of the foot, and has a higher contact with the foot than other parts of the sock, thereby further suppressing the sock from coming off.

The silicone layer is formed on the inner surface of the band part formed on the surface in contact with the heel of the foot, as shown in FIG. 2, and may basically have a linear shape with a predetermined width smaller than the width of the band part. In consideration of the fact that peeling occurs when an external force is applied in the insertion direction of the foot, it is preferable to form an arc or arch shape curved at a certain angle in the insertion direction of the foot.

The silicon layer may be provided singly, but may be provided in a plurality of two or more to further increase frictional force with the heel. At this time, when the silicon layer is provided in plurality, it may be provided in parallel with the insertion direction of the foot to increase resistance to external force transmitted in the corresponding direction, and perpendicular to the insertion direction, that is, along the inner surface of the band portion toward the entrance of the sock. By arranging a plurality of them, the contact area between the foot and the silicon layer can be further widened and form stability can be secured when worn.

The material of the silicone part is not limited as long as it can be coated on the inner surface of the band part in a linear shape as described above, and specifically, it is preferable to use a material having high friction fastness and excellent weather resistance and processability, such as liquid silicone rubber.

The liquid silicone rubber elastomer is a liquid rubber elastomer obtained by mixing and crosslinking fine powder, silica, etc. with a straight chain diorganopolysiloxane having a high degree of polymerization as a reinforcing material. Since it is created by simply applying and curing the composition of the band, there is an advantage of excellent workability.

In particular, polyurethane, which is generally used to increase frictional force, has a main chain composed of carbon and carbon bonds (C-C), but over time, it is dehydrogenated and decomposed into ethylene bonds (vinyl bonds, -CH=CH-). It happens. However, the liquid silicone rubber elastomer as described above has excellent heat resistance, chemical resistance, and abrasion resistance as the main chain is formed of Si=C bonds even over time.

The liquid silicone rubber elastomer has a higher molecular weight than silicone oil, and although the molecular weight is not limited, the molecular weight is about hundreds of thousands, the specific gravity is 0.98, the refractive index is 1.40, and the viscosity range is 1 to 10 Pa·s.

As described above, the silicone layer may be formed by applying a liquid silicone rubber elastic body to a wide portion of the inner surface of the band portion (the portion in contact with the heel of the foot) in a predetermined size and then drying it. At this time, the silicone layer may be left at room temperature (around 20 ° C.) for a certain period of time after application to promote solvent evaporation or shape stability, and then washed with water to remove unadhered silicone elastic bodies or other remaining solvents.

Overshoe socks according to the present invention is a band part to have a certain width along the receiving port (entrance) of the foot among the inner surface of the instep part and the side part in the overshoe in which a space for accommodating the foot is formed by sewing the bottom part, the instep part, and the side part And since the band portion is attached to the surface in contact with the side portion, it is possible to prevent peeling even after a violent movement after wearing, and to express elasticity and fixing power.

In addition, by increasing the width of the band part formed on the heel part of the foot as needed compared to other parts, it is possible to mitigate the shock transmitted to the heel of the foot and at the same time suppress damage to the skin due to friction with the shoe. By further forming, frictional force and cushioning properties can be further increased.

Hereinafter, the present invention will be described in more detail by way of Examples and Comparative Examples.

Specifically, as test strains, Staphylococcus aureus (positive bacteria, Staphylococcus aureus: ATCC 6538) and negatively designated bacteria Klwbsiella pneumoniae (negative bacteria, Klwbsiella pneumoniae: ATCC 4352) were used as test strains. , After inoculating the filament, the initial number of bacteria (Staphylococcus aureus: 1.4 × 10 ⁵ /mL, Klebsiella pneumoniae: 1.8 × 10 ⁵ /mL) and the number of bacteria 18 hours after incubation were measured and measured by substituting into the following equations 2 and 3 .

[Equation 1]

[Equation 2]

(Where M _a : The number of viable cells immediately after inoculation of the test piece to which no antimicrobial substance was added

M _b : The number of viable cells after 18 hours of incubation of the test piece without the addition of antimicrobial substances

M _c : The number of viable cells after 18 hours of incubation of the test piece to which the antibacterial substance was added)

(tensile strength)

After cutting the specimen prepared through the following examples to a size of 5 cm in width and 10 cm in length, clamp the specimen in the load cell clip of the tensile strength measuring instrument (Instron 4443, Instron corporation) and set the crosshead speed to 50 mm /min, and the load cell was measured at 100 kgf to measure the tensile strength.

(Examples 1 to 3)

It is prepared in the form of a knitted fabric (fineness 50, CM26S / 2 100) for the manufacture of the bottom, but when manufacturing the knitted fabric, cotton fiber and elastic fiber (polyurethane) are mixed with 80% by weight and 20% by weight, respectively. Example 1) and cotton fibers and elastic fibers, when spinning polyurethane, 80% by weight and 20% by weight of elastic fibers obtained by adding 2 parts by weight of polyhexamethyleneguanidinium to 100 parts by weight of the spinning solution, respectively (Example 2) and cotton fiber, the elastic fiber and polylactic acid fiber of Example 2 were used, respectively, 75% by weight, 18% by weight, 7% by weight of plied yarn (Example 3). The mechanical properties and antibacterial properties of the bottom portion prepared as described above were measured and listed in Table 1 below.

[Table 1]

As shown in Table 1, it can be seen that the socks manufactured according to the present invention have excellent antibacterial properties and at the same time secure a certain tensile strength. Specifically, compared to Example 1 using general cotton fiber and polyurethane elastic fiber, Example 2 using the elastic fiber with an antibacterial component added a significant increase in the bacteriostatic reduction rate without a significant change in tensile strength. It can be seen that Example 3, in which lactic acid fibers were further plied, showed the best bacteriostatic reduction rate, and at the same time, the tensile strength also increased. It seems that the efficiency of bacteriostatic reduction was increased due to the negative charge formed on the surface of the polylactic acid fiber, and the tensile strength also increased due to the occurrence of electrostatic bonding with the positive charge formed on the surface of the polyurethane elastic fiber.
