Detailed description

The thermal management nonwoven has a polymeric binder dispersed throughout its interior, while the thermal management nonwoven also has a binder dispersed throughout its interior. The binder can be either continuous or discontinuous in the nonwoven, as will be explained. The thermal management nonwoven material of the present invention provides protection against cold or hot environments by absorbing and/or releasing heat from the thermal management material.

Nonwoven fabrics can be composed of a wide variety of substances. For example, nonwoven fabrics are composed of cellulose, polyolefins (such as polyethylene, polypropylene, etc.), polyesters, polyamides (such as nylon), bicomponent materials or mixtures of the above, and even inorganic fibers. These fiber lengths can range from about 0.3 to 7 cm, depending on the desired method of web formation and bonding, alternatively, the filaments can be longer, including spunbonding/melt blowing of molten polymers Continuously extruded filaments or fabrics. Fiber lengths may range from about 0.5 to 30 denier.

Nonwoven fabrics are produced in two distinct steps: the first step is to form loose battings or webs, and the second step is to bond these battings or webs, for example using adhesives, or at the junction of these battings or webs These batts or webs are physically fused, or entangled, into nonwoven fabrics.

Web formation may be performed using any method known in the art, for example, by a dry-laid process in which the monofilaments are carded into substantially parallel piles or monofilaments using rotating rollers with fine teeth along the edges. to the net. These unidirectional webs can be cross-laid into a web-forming process in which individual unidirectional webs are stacked at an angle to each other. Alternatively, webs can also be made, for example, by a wet-laying process, in which the fibers are dispersed in water and passed through a belt screen, from which the water is squeezed to form the web on the belt. This method produces dense, uniform and strong webs. Non-oriented fiber webs (isotropic) webs can be produced by air deposition, which involves randomly blowing the fibers onto a screen. In another embodiment, the fibers can be placed randomly on a pre-formed nonwoven scrim that is used in place of the screen. For example, fibers can be blown onto a pre-formed web with a binder in which a thermal management material is dispersed to form a two-layer product with one layer having thermal management properties and one layer without such properties. For example, such a product can form a layer of about 200 g/m ² with a nonwoven fabric containing a thermal control material, while another layer of nonwoven fabric of about 200-800 g/m ² is blown onto the thermal control nonwoven.

Randomized webs can also be made by meltblowing, in which fibers are spun directly from the polymer and torn into different lengths with an air stream, then deposited to form a matrix. In addition, the spunbond process can also be used to produce endless fiber filaments from raw material particles. The fibers are deposited into a web by (hot air) stretching. This method is a single-step continuous process for the production of nonwoven fabrics.

For the construction of insoles, nonwovens can take many forms. The type of material used depends on the desired end use of the material. For insole materials, the nonwoven fibers preferably comprise a hard, rigid board formed, for example, of a blend of polyester fibers having a range of dtex values with a rigid polymeric binder. For air-cushioned insoles, the nonwoven fibrous web preferably contains, for example, a mixture of detex about 6 coarse polyester fibers with a soft resilient polymeric binder to give the material a resilient and open structure.

After the webs are formed, in some embodiments, after any final light pre-bonding of the webs (described below), they are dipped into a bath containing a suspension or dispersion of polymeric binder and thermal control material . A nonwoven fabric is formed according to the method described herein wherein the webs are bonded together with an adhesive at least at intersection points. In some embodiments, the web is substantially continuously filled with the polymeric binder, while in other embodiments, the polymeric binder is present substantially only at the junctions of the webs, and the gaps are substantially filled with a gas such as air . Binders useful in the fabrics of the present invention are solid at the fabric use temperature and preferably form rinseable and dry cleanable nonwoven fabrics. If a solvent is used, the binder may have a high melting point. However, suitable binders are generally fluid, if not soluble, below the softening point of the web matrix material. Some suitable binders are polymeric materials. Particularly useful are polymer emulsions or dispersions which can form adhesive and/or cohesive bonds in the network, for example by crosslinking themselves or with the network. Examples of polymeric binders include acrylic and polyacrylic resins, methacrylic and polymethacrylic resins, polyurethane, nitrile rubber, styrene/butadiene copolymer, chloroprene rubber, polyvinyl alcohol , or ethylene/vinyl acetate copolymer, and mixtures thereof.

Latex adhesives can also be used, including water-based latex blends. Advantageously the latex adhesive comprises a hard styrene/butadiene rubber latex. The binder preferably includes a thickener such as ammonia and an acrylic rubber capable of reacting with the thickener, such as ammonia, to thicken the mixture. For example, a suitable latex adhesive contains a blend of 75% by weight application polymer S30R and 25% by weight Synthomer ^™ 7050. This mixture can be thickened with ammonia and an acrylic rubber such as Viscalex ^™ HV30 (manufactured by Allied Colloids).

Examples of thermal control materials include phase change materials as described below.

This immersion step is carried out to such an extent that the suspension or dispersion is substantially completely immersed in the web. The bath can be heated to hot melt bond the fibers at the intersections. The web is then dried to remove any solvent (ie water), thus obtaining a nonwoven fabric with adhesive and thermal control material at the intersections of the web materials. Alternatively or additionally, the web may be passed through rollers which may or may not be heated. Warm or hot air can also be used to dry the web. In some embodiments, the resulting web intersections are substantially filled with adhesive and thermal control material.

In a preferred embodiment of the invention the adhesive is almost entirely at the intersections of the mesh itself and the rest of the intersections are filled with gas, typically air, to impart thermal insulation properties to the material. Turning to FIGS. 1 and 2 , there is shown a portion of a nonwoven fabric 1 comprising a web material 2 with joins 3 and intersections or voids 4 . Adhesive 5 is dispersed in various places of the net and located at the joints of the fibers of the net material, and thermal control material 6 is fully dispersed. In certain embodiments, the remainder of the web does not contain binder. The adhesive acts as a binder to attach the web to itself and as an adhesive to attach the thermal control materials to each other and to the web, which results in a bonded nonwoven fabric with the thermal control material dispersed therein.

The nonwoven fabrics of these embodiments can be prepared using the adhesive surface tension and the affinity of the adhesive for the web and itself. Adhesives that exhibit excessive self-adhesion do not tend to bond the web at all, while adhesives that exhibit excessive affinity for the web do not form islands or globules at web intersections. The speed at which any solvent is removed from the adhesive will also have an effect on the extent to which islands and globules are formed at web intersections. Solvent removal is too fast and the adhesive cannot migrate towards the web contact. Those skilled in the art generally select a grade of solvent removal rate that is well matched to the affinity properties of the adhesive.

In other embodiments, the web is substantially completely impregnated with a binder with the thermal control material dispersed throughout the binder. Depending on the application in the embodiment, the binder material for filling the mesh is required to be relatively elastic, or may also be required to be relatively hard.

The viscosity of the adhesive can also be adjusted to produce a nonwoven fabric that coagulates the adhesive at the web bonds. In these embodiments, the adhesive sets at the intersections of the webs, as shown in FIGS. 1 and 2 . Bonding of the web is preferably performed immediately after web formation, ie by dipping the web into a binder bath containing the thermal control material. In addition, light pre-bonding treatments including adhesive spray bonding, thermal bonding, needle punching and water jet bonding can be used before the web dipping operation and the final bonding of the nonwoven product. carried out before. These treatments can impart various qualities to the finished product, as is well known to those skilled in the art. For example, needle punching or water jet bonding can be used to produce relatively dense and stiff nonwovens, as well as relatively light bulky nonwovens, depending on the needling or water jet density and pressure. In certain embodiments, nonwoven needle felt webs are preferred. In a further example, the spun bonded web may be dipped into the chemical bath as described above after it has been bonded.

Thermal control materials that can be used in fabrics are those suitable for protection against cold and/or heat. Particularly useful thermal control materials include phase change materials. Encapsulated, particularly microencapsulated, phase change materials are useful in the present invention. Microcapsules suitable for use in the present invention may comprise a wide variety of materials. The choice of materials is limited only to the fabric treatment conditions disclosed herein. The microcapsules suitable for the present invention have a diameter of 15.0-2000 μm, preferably 15-500 μm, most preferably 15-200 μm. Phase change materials are also well suited for encapsulation in microcapsules, where the diameter of the microcapsules can be the same or larger than the diameter of the material making up the nonwoven fabric.

Phase change materials utilize latent heat absorption associated with reversible phase transitions such as solid-liquid transitions. Certain phase change materials also absorb or release heat during solid-solid phase transitions. In this way, the material can be used as a heat absorber to prevent the object from absorbing additional heat, because the phase change material can absorb a certain amount of thermal energy before the temperature rises. Phase change materials can also be preheated to act as a protective barrier against cold, since a greater amount of heat must be removed from the phase change material before the temperature of the phase change material begins to drop. Preferred phase change materials of the present invention utilize reversible solid-liquid transitions.

Phase change materials store thermal energy in the form of a physical change of state when the core material in the microcapsules melts or solidifies or undergoes a solid-solid transition. These materials will absorb or release heat at a certain constant temperature (their phase transition temperature) before the phase transition. In this way, these materials can be used as heat absorbers, so that some thermal energy is absorbed by the phase change material before the temperature of the object rises, preventing the object from absorbing excess heat. Phase change materials can also be preheated to act as a protective barrier against cold, since a greater amount of heat must be removed from the phase change material before the temperature of the object begins to drop. In order to maintain the ability of phase change materials to cycle between solid and liquid phases, it is important to protect these phase change materials from complete dispersion by solvents (or carrier fluids) while they are in the liquid state. One approach that has been successful is to encapsulate these phase change materials in films or shells. These films or shells need not unduly impede heat transfer into or out of the capsule. It is also desirable that the capsules be small enough to have a relatively high surface area. This allows heat to be transferred rapidly to and from the carrier fluid. These capsules, known as microcapsules, have a size of about 10-50 um and can be made according to conventional methods well known to those skilled in the art. It should be effective for heat to traverse the microcapsules into their interior for maximum utilization in the present invention.

The composition of phase change materials can be varied to achieve optimal thermal performance within a given temperature range. For example, as shown in the table below, the melting point of paraffinic hydrocarbons (ordinary, straight-chain hydrocarbons with the structural formula _{CnH2n +2} ) is directly related to the number of carbon atoms.

Table 1. Alkanes phase transition temperature

Compound name Number of sulfur atoms Alkane point(°C) n-decane 10 -32 n-undecane 11 -26 n-dodecane 12 -11 Tridecane 13 -5.5 Tetradecane 14 5.9 Pentadecane 15 10.0 n-Hexadecane 16 18.2 n-heptadecane 17 22.0 n-octadecane 18 28.2 n-nonadecane 19 32.1 n-Eicosane 20 36.8 n-Hecodecane twenty one 40.5 n-docosane twenty two 44.4 Tricosane twenty three 47.6 Tetracosane twenty four 50.9 n-pentacane 25 53.7 n-Hexacosane 26 56.4 n-Heptacane 27 59.0 n-Octadecane 28 61.4 n-Nonacosane 29 63.4 Triadecane 30 65.4 n-triundecane 31 68.0 n-Docosane 32 70.0 Tritrisane 33 71.0 n-Three tetradecane 34 72.9 n-Hexacosane 36 76.1

In addition to the alkanes listed here, other paraffinic alkanes having a greater (or lesser) number of carbon atoms and a higher (or lower) melting point can also be used in the practice of the present invention. In addition, plastic crystals such as 2,2-dimethyl-1,3-propanediol (DMP) and 2-hydroxymethyl-2-methyl-1,3-propanediol are also conceivable as temperature stabilizers. If a plastic crystal absorbs thermal energy, it only changes the molecular structure and does not leave the solid phase.

Combinations of any phase change materials are also possible. Microencapsulated phase change materials (MicroPCM) require uniform distribution in the polymer binder. In some embodiments, the MicroPCM can be predispersed in water using a dispersant such as Dispex ^™ A40 prior to mixing with the latex binder. According to these embodiments, the phase change material is preferably about 30-60 wt% solids dispersed in water, or preferably about 40-45 wt%, relative to the weight of the water. When it is desired to prepare a water/MicroPCM mixture, it is preferred that the water/MicroPCM mixture is mixed with the latex binder such that the ratio of MicroPCM to latex is about 0.5 to 2:1. The ratio of dry binder to base nonwoven is preferably About 0.3:1～3:1. This preferred ratio depends on the desired properties of the finished product. For padded insoles, the ratio is preferably about 0.3 to 0.5:1. For lining materials, the ratio is preferably about 1:1 and for hard insoles, the ratio is preferably about 2.5:1. Optionally, the adhesive mixture may contain colorants.

Examples of phase change materials are paraffinic alkanes, ie (linear) alkanes with the structural formula _{CnH2n +2} , wherein n is 10-30, preferably n is 13-28. Other suitable phase change material compounds are 2,2-dimethyl-1,3-propanediol (DMP), 2-hydroxymethyl-2-methyl-1,3-propanediol (HMP) and similar compounds. Fatty esters such as methyl palmitate are also useful. Paraffinic alkanes are preferred as phase change materials.

By providing regeneration of the phase change material, the thermal management properties of the fabrics disclosed herein can be made reversible. During warming, for example, the phase change material gradually melts; during cooling, the phase change material gradually solidifies. One way to regenerate a phase change material is to place the nonwoven fabric in an environment at a temperature that restores the phase change material to the proper phase needed for protection.

For most embodiments, the composition of the phase change material has a melting or activation temperature of about 15-55°C (60-130°F), with a beneficial range of 26-38°C (80-100°F). For most applications, the activation temperature is preferably about 28°C (83°F). Conveniently, different grades of phase change material can be suitable for different applications. For example, applications with a high activation temperature of about 35°C (95°F) are advantageous for insole applications, while lower activation temperatures of about 28°C (83°F) are useful for uppers or tongues. Various activation temperatures can be selected to satisfy the natural differences of the skin from sole to instep.

The specifications of the thermal management materials discussed here can vary depending on their intended use. The weight of the web is about 15-1000 g/m ² , preferably about 40-700 g/m ² or about 50-150 g/m ² .

For example, when used as an interlayer or insulation for clothing or footwear, the fiber web has a weight of about 15-200 g/m ² , preferably about 50-160 g/m ² . Such a web is capable of loading about 5-600 g/ ^m2 of binder and phase change material, preferably about 50-450 g/m2 of binder and phase change material. When used as an interlayer or for clothing and footwear, the thickness of the nonwoven fabric is about 0.5 up to 20 mm. As an insole or material lining, the initial thickness is preferably about 0.5-5 mm, however, as an air-cushioned insole, the initial thickness is about 5-15 mm.

The present invention further provides a method for manufacturing insole or lining material, which comprises the following steps: 1) mixing microencapsulated phase-change materials and liquid polymer adhesives, wherein the phase-change materials contain A material with reversible heat storage properties and an activation temperature close to body temperature (where body temperature is the normal physiological temperature of the skin); 2) impregnating the nonwoven fabric matrix material with the binder mixture; and 3) drying the impregnated material . Preferably the method further comprises the step of predispersing the microencapsulated phase change material in water prior to mixing with the liquid polymeric binder. The microencapsulated phase change material is preferably predispersed in water using a dispersant such as Dispex ^™ A40. Preferably the method further comprises the step of adding a thickener to the binder mixture. It has been found that increasing the viscosity of the mixture is beneficial for improving stability, reducing their separation from the microcapsules during impregnation, and resulting in a better appearance of the finished product. The impregnated material is preferably dried at about 120°C, and the method preferably also includes the step of curing the polymeric binder material. The curing step is advantageously carried out at a temperature of about 140°C. The method also preferably further includes the step of finishing the material, such as sorting the material into desired specifications, texturizing the nonwoven lining surface and applying an adhesive or protective coating to aid in the shoemaking process.

The present invention further provides an insole comprising a nonwoven base material, a polymer binder and a microencapsulated phase change material dispersed in the binder, wherein the phase change material contains Materials with reversible heat storage properties, and phase change materials have an activation temperature close to body temperature (where body temperature is the normal physiological temperature of the skin).
