Description

Treatment agent for polyolefin synthetic fibers, and heat-bonded nonwoven fabric
Technical Field
The present invention relates to a treatment agent for polyolefin synthetic fibers, and thermally bonded nonwoven fabric.
Background
Generally, polyolefin synthetic fibers are used as raw material fibers of nonwoven fabrics. For example, in the production of nonwoven fabrics, short fibers (staple) of polyolefin-based synthetic fibers are produced first, and then the short fibers are passed through a carding machine to produce a carded web. Then, the carded web is subjected to a hot air treatment by a thermal bonding method to bond the short fibers to each other, thereby manufacturing a nonwoven fabric.
Further, the short fiber is coated with a treatment agent for polyolefin synthetic fibers to impart functions such as hydrophilicity in an unused state (hereinafter referred to as initial hydrophilicity) and hydrophilicity in a multiple use state (hereinafter referred to as durable hydrophilicity) to the nonwoven fabric. Nonwoven fabrics to which these functions are imparted are used in a wide range of fields such as sanitary materials, medical fields, and civil engineering fields.
Patent document 1 discloses a fiber treating agent as a treating agent for polyolefin-based synthetic fibers, which contains an anionic surfactant and a nonionic surfactant. As an anionic surfactant, patent document 1 discloses a phosphate salt having an alkyl group having 6 to 10 carbon atoms. As a nonionic surfactant, patent document 1 discloses an alkylene oxide adduct which is an esterified product of a hydroxy fatty acid having 6 to 22 carbon atoms and a polyhydric alcohol.

Test class 2 (production of polyolefin-based synthetic fibers and thermally bonded nonwoven fabrics)
Polyolefin synthetic fibers and heat-bonded nonwoven fabrics were produced using the treatment agent for polyolefin synthetic fibers prepared in test class 1.
First, the treatment agent prepared in test type 1 was attached to a composite fiber (fineness 2.2dtex, fiber length 51 mm) in which the sheath portion was polyethylene and the core portion was polyester, so that the solid content was attached in an amount of 0.35 mass% (no solvent contained). The treatment agent is applied by a spray method (spray oil method). Next, the resultant was dried by a hot air dryer at 80℃for 1 hour to prepare a polyolefin synthetic fiber sponge as a polyolefin synthetic fiber. Then, the polyolefin synthetic fiber cotton was passed through a drum-type carding machine to form a cotton having a weight of 20g/m 2 Is a carded web. Then, the carded web was subjected to a heat-treatment with a heat-blast at about 140 ℃ for 10 seconds to bond the fibers to each other, thereby producing a heat-bonded nonwoven fabric.
Test class 3 (evaluation)
The evaluation items of the process performance of the treatment agents described in examples 1 to 12, reference examples 1 to 9 and comparative examples 1 to 11 were to evaluate the antistatic property and the comb-passing property. The evaluation items of the nonwoven fabric were the initial hydrophilicity, durable hydrophilicity, initial hydrophilicity after time, and durable hydrophilicity after time. The sequence of each test is shown below. The test results are shown in the "antistatic" column, the "comb passing" column, the "initial hydrophilic" column, the "durable hydrophilic" column, the "initial hydrophilic after time" column, and the "durable hydrophilic after time" column in table 1, respectively.
(antistatic property)
5g of the polyolefin-based synthetic fibers to which the treatment agents described in examples, reference examples, and comparative examples were attached were humidified in a constant-temperature chamber having a relative humidity of 45% at 20℃for 24 hours. Then, the resistance of the polyolefin-based synthetic fiber was measured by using a known resistance measuring device, and evaluated using the following evaluation criteria.

Very good: the discharge amount is more than 80 percent
(yet): the discharge amount is more than 60% and less than 80%
X (bad): the discharge amount is less than 60% (initial hydrophilicity)
The thermally bonded nonwoven produced in test class 2 was humidified in a 65% oven at 20℃for 24 hours. The humidified nonwoven fabric was placed on a horizontal plate, and 0.4ml of water was dropped into the nonwoven fabric from a height of 10mm using a burette. To visually observe the state in which the water droplets are absorbed. The time until the water droplets were completely absorbed was measured, and evaluated using the following evaluation criteria. The state in which the water droplets are completely absorbed is hereinafter referred to as water penetration.
Evaluation criterion of initial hydrophilicity
Very good: the time required for water permeation is less than 1 second
(yet): the time required for water permeation is 1 second or more and less than 2 seconds
X (bad): the time required for water permeation is more than 2 seconds
(durable hydrophilic)
The thermally bonded nonwoven produced in test class 2 was cut into 10cm×10cm pieces. The sheeted nonwoven fabric was humidified in a constant temperature chamber having a relative humidity of 60% at 20℃for 24 hours. The humidified nonwoven fabric was placed on 5 sheets of filter paper. Then, a cylinder having an inner diameter of 1cm and open at both ends was placed on the center of the nonwoven fabric so that the axial direction was a vertical direction.
10ml of 0.9% physiological saline was poured into the cylinder. The state of absorption of the physiological saline by the nonwoven fabric was visually observed, and the time until the physiological saline was completely absorbed was measured.
Then, the nonwoven fabric was taken out, and the nonwoven fabric was blown with warm air at 40 ℃ for 90 minutes to dry the nonwoven fabric by air blowing. After the air-blown drying, the test of humidifying the nonwoven fabric and absorbing physiological saline was repeated 3 times again. The results of the 3 rd pass were evaluated using the following evaluation criteria.
Evaluation criterion of durable hydrophilicity
Very good: the time required for the physiological saline to be completely absorbed is less than 5 seconds
(yet): the time required for the physiological saline to be completely absorbed is more than 5 seconds and less than 7 seconds
X (bad): the time required for the physiological saline to be completely absorbed is more than 7 seconds
(initial hydrophilicity after time and durable hydrophilicity after time)
The heat-bonded nonwoven fabric produced in test class 2 was stored in a constant temperature chamber at 70℃for 2 weeks. Then, the mixture was humidified in a constant temperature chamber having a relative humidity of 60% at 20℃for 24 hours. The nonwoven fabric after humidification was evaluated by the same evaluation method and evaluation standard as those for the initial hydrophilicity and durable hydrophilicity described above.
From the results in table 1, it is clear that the decrease in both initial hydrophilicity and durable hydrophilicity of the nonwoven fabric with time can be suppressed according to the present invention.
