Benefits of technology

The present invention provides a fabric and textile product with durable moisture absorbency and flame retardance.

Problems solved by technology

In addition, fire-fighting clothing and work clothes had the problem of excessive perspiration since there are many opportunities for use in environments at high temperature and humidity.
However, since priority was placed on protecting firefighters and workers from fire and the like, little consideration has been given to wear comfort of fabric.
However, a fabric has yet to be proposed that demonstrates durable moisture absorbency in addition to flame retardance.

example 1

[0079]Staple fibers respectively consisting of meta-type wholly aromatic polyamide fibers composed of Conex® (MA), para-type wholly aromatic polyamide fibers composed of Twaron® (PA), and electrically conductive nylon fibers composed of No Shock® (Solcia Co., Ltd.) (NY) (each having a fiber length of 51 mm) were formed into two-ply spun yarn having a yarn count of 40 obtained by blending MA, PA and NY at a weight ratio of 93 / 5 / 2, weaving into a plain weave having a weaving density in the warp direction of 56 threads / 25.4 mm and weaving density in the weft direction of 48 threads / 25.4 mm, and subjecting to singeing and scouring under processing conditions employed in ordinary methods, followed by imparting a hydrophilizing agent containing polyethylene terephthalate-polyethylene glycol copolymer by a padding treatment method, and subsequently subjecting to heat setting at 180° C. to obtain a plain weave fabric having a basis weight of 150 g / m2 and adhered amount of hydrophilizing age...

example 2

[0081]Example 2 was carried out in the same manner as Example 1 with the exception of blending staple fibers respectively consisting of meta-type wholly aromatic polyamide fibers (MA), para-type wholly aromatic polyamide fibers (PA), electrically conductive nylon fibers (NY) and flame-retardant polyester fibers (PE) (each having a fiber length of 51 mm) at a weight ratio of MA / PA / NY / PE of 73 / 5 / 2 / 20 into two-ply spun yarn having a yarn count of 40.

[0082]Moisture absorption performance as defined in AATCC79 in the resulting fabric was initially 0.9 seconds and 11 seconds after 20 cycles of laundering as defined in ISO6339-2012 (6N-F), demonstrating that the fabric has superior moisture absorbency. In addition, afterflame obtained by measuring flammability as defined in Method A-4 of JIS L1091-1992 was 2.0 seconds or less and did not present a problem. When work clothes were fabricated using this fabric and worn, they were determined to absorb perspiration when perspiring and have supe...

example 3

[0083]Example 3 was carried out in the same manner as Example 2 with the exception of weaving a double fabric having a weaving density in the warp direction of 56 threads / 25.4 mm and weaving density in the weft direction of 60 threads / 25.4 mm as in Example 2 in accordance with the weave structural diagram shown in FIG. 1.

[0084]Moisture absorption performance as defined in AATCC79 in the resulting fabric was initially 0.6 seconds and 9.0 seconds after 20 cycles of laundering as defined in IS06339-2012 (6N-F), demonstrating that the fabric has superior moisture absorbency. In addition, afterflame obtained by measuring flammability as defined in Method A-4 of JIS L1091-1992 was 2.0 seconds or less and did not present a problem. When work clothes were fabricated using this fabric and worn, they were determined to absorb perspiration when perspiring, not stick to the skin, and have superior wear comfort.

Abstract

In order to provide a fabric and a fiber product, which have hygroscopicity and durability as well as flame retardancy, a hydrophilizing agent is added to a fabric containing aramid fibers.

Description

TECHNICAL FIELD[0001]The present invention relates to a fabric and fiber product having durable moisture absorbency in addition to flame retardance.BACKGROUND ART[0002]Fabric containing aramid fibers has conventionally been used in fire-fighting clothing and work clothes due to the superior flame retardance thereof. In addition, fire-fighting clothing and work clothes had the problem of excessive perspiration since there are many opportunities for use in environments at high temperature and humidity. However, since priority was placed on protecting firefighters and workers from fire and the like, little consideration has been given to wear comfort of fabric.[0003]On the other hand, a fabric that efficiently absorbs perspiration has been proposed for use as a fabric that enhances wear comfort when perspiring (see, for example, Patent Document 1).[0004]However, a fabric has yet to be proposed that demonstrates durable moisture absorbency in addition to flame retardance.PRIOR ART DOCUM...
