Definitions
- the present invention relates to a fabric in which fibers that change in size upon special water absorption are mixed. More specifically, the present invention provides a fabric that is comfortable when sweating while wearing a cellulosic fiber that undergoes a dimensional change (water absorption self-extension or water absorption self-shrinkage) upon water absorption.
- the garments proposed in these patent documents are more comfortable when sweating than garments that do not use water-absorbing self-extending yarns.
- the fibers used in these clothes do not absorb moisture from the body's insensitive digestion, which has almost no hygroscopicity or water absorption. For this reason, there is a feeling of discomfort even when worn in a non-sweat state, and furthermore, since it does not absorb sweat even when sweating, it becomes a garment with a feeling of stuffiness.
- ordinary cellulose fibers are used, they are comfortable when worn due to their good hygroscopicity.
- a high-functional fabric is desired, for example, since it feels sticky when sweating due to exercise or the like, and feels stuffy when breathing water, improving air permeability. As mentioned above, there are currently no fibers that are comfortable when worn and when sweating.

- a cellulose fiber-mixed fabric characterized by containing cellulose fibers having a dimensional change rate of 2% or more upon water absorption.
- the outer layer and Z or intermediate layer contain water-absorbing self-shrinking cellulose fibers with a water absorption elongation rate of 2% or less, and the other outer layer is composed of non-water-absorbing shrink fibers, and the non-separating part in the course direction is not contracted.
- a three-dimensionally structured fabric in which a separation part and a non-separation part are formed repeatedly, and one outer layer (C) constituting the separation part has a water-absorption self-shrinking cell having a water absorption elongation rate of 2% or less.
- Cellulose fiber according to (7) characterized in that it contains roulose fibers, the other outer layer (D) contains non-water-absorbing shrink fibers, and the number of courses of both outer layers is (C)> (D) Mixed fabric.
- the fiber of the present invention By using the fiber of the present invention, it is possible to produce a fabric that is comfortable when worn and does not feel stuffy when sweating. In particular, this fabric can exert a significant moisture absorption / release effect during exercise, and there is a large difference in clothes and wearing comfort as shown in Patent Documents 1 to 5 proposed so far.
- the size of the cellulose fibers changes during water absorption (when sweating in clothes), and the moisture absorption and release characteristics can be improved.
- the effect of changing the water absorption dimension of cellulose fibers can be obtained. For this reason, if the fiber of the present invention is used, it is possible to produce a garment that is comfortable when worn and has no stuffiness if it feels sticky when sweating. When the fabric produced using the fiber of the present invention is applied to sportswear, inner, outer, etc., a comfortable wearing feeling can be obtained.

- the cellulose fiber in the present invention includes cupra, rayon, purified cellulose fiber, bamboo fiber, cotton and the like, and regenerated cellulose such as cuvula and rayon is preferably used.
- these long fibers and short fibers are used.
- l ldt decitex: the same symbol is used
- 160 S cotton count: the same symbol is used
- it can be configured by twisting long fibers and short fibers, twin yarn, triple-filament, or long fibers and short fibers, and each can be used as a thickness suitable for the structure.
- 40dt to 170dt is preferred, and for short fibers, about 30S to 120S is easy to handle.
- the fabric of the present invention is a fabric in which cellulose fibers having a dimensional change rate of 2% or more upon water absorption are mixed.
- cellulose fibers having a dimensional change rate of 2% or more upon water absorption There are two types of cellulose fibers having a dimensional change rate of 2% or more upon water absorption: water-absorbing self-extending cellulose fibers and water-absorbing self-shrinking cellulose fibers.
- the inventors of the present invention have found a method for suitably obtaining water-absorbing self-extending cellulose fibers and water-absorbing self-shrinking cellulose fibers, and studied fabric configurations for making the best use of the respective performances, and reached the present invention.
- the water-absorbing self-extending cellulose fiber is a cellulose fiber having a water absorption elongation rate of + 2% or more, preferably a water absorption elongation rate of + 3% or more.
- the water-absorbing self-shrinking cellulose fiber refers to a cellulose fiber having a water absorption elongation rate of 2% or less.
- a fiber having a dimensional change rate of less than 2% at the time of water absorption is referred to as a normal fiber.
- Common fibers include polyester fibers such as polyester and polytrimethylene terephthalate, polyamide fibers, polyurethane fibers, cellulose fibers that are not given the ability to change water absorption due to alkali treatment or twisted yarn, which will be described later, acetate, wool, etc. And long fibers or short fibers of any fiber.
- These cross-sectional shapes are arbitrary, and may be irregular yarns such as round cross-sections and W-shaped cross sections.
- the dimensional change rate during water absorption is determined by the following method. Measure the fiber length (A) under a load of 0.05 g / dt (decitex) in an environment of 20 ° C and 65% RH, and then immerse the fiber in water for 30 seconds. Next, the fiber is taken out from the water, and the fiber length (B) after 30 seconds is measured under a load of 0.05 gZdt.
- the water absorption elongation rate is obtained by the following formula (1). And below As shown in formula (2), the absolute value of the water absorption elongation obtained is the dimensional change rate during water absorption.
- the measurement of the dimensional change rate during absorption of fibers in the fabric is carried out under the same conditions by extracting the fibers from the fabric.
- the fiber length to be measured is 30 cm.
- the length is measured.
- the number of measurement samples should be increased as appropriate.
- the fiber is extracted from the fabric, Measure the rate of dimensional change at the time of water absorption under the same conditions in the state of blended yarn and twisted yarn.
- the water-absorbing self-extending cellulose fiber of the present invention has a water absorption elongation rate of + 2% or more, preferably + 3% or more.
- ordinary cellulose fibers should be treated in an alkaline aqueous solution. It has been conventionally known that a cellulose fiber is alkali-treated. For example, mercerization is the most common treatment method.
- the present inventors succeeded in producing a cellulose fiber that stretches by 2% or more, preferably 3% or more upon water absorption.
- cellulose fibers can be obtained by immersing cellulose fibers in an aqueous solution containing, for example, 20 gZL (liter) or more of sodium hydroxide at 20 ° C or more for 5 minutes or more.
- the water absorption elongation rate can be controlled by controlling these conditions. For example, it is possible to obtain a cellulose fiber having a water absorption elongation rate of 20% or more, for example, 20% or more, even if the treatment conditions are too strict. Have difficulty.
- Known alkali treatment agents can be used.
