Embodiment 1

[0167] A circular knitting machine with a gauge (gauge) 28 is used to weave the circular rib structure. At this time, the ordinary fibers and the cellulose fibers are arranged and woven alternately. In this weaving, 84dt / 36f polyester fiber 84dt / 45f copper ammonia fiber was used as the cellulose fiber and the 84dt / 45f cupro fiber was used as the normal fiber. At this time, the cupro fibers used are ordinary cupro fibers that have not been subjected to alkali treatment.

[0168] Put the woven gray fabric into a liquid flow dyeing machine, refine it at 80°C for 20 minutes, drain it, and then treat it with alkali at 30°C for 20 minutes with a concentration of 60g / L of sodium hydroxide. Next, only the ester side was dyed at 130°C. Since the dyed knitted fabric becomes uneven, it was dried using a short-ring dryer, stretched with a pin tenter until the wrinkles of the knitted fabric can be removed, and set at 170° C. for 60 seconds. In addition, at the time of this dyeing, it dye...

Embodiment 2～8

[0171] Cellulosic fibers having different water-absorbing elongations were produced by changing the alkali treatment conditions and the types of cellulosic fibers in Example 1. Table 1 shows the results of evaluating the wearing comfort of the knitted fabric using this fiber.

Embodiment 9

[0173] The raw polyester fiber 56dt / 24f of ordinary fiber as the warp, the raw polyester fiber 56dt / 24f of ordinary fiber as the weft, and the 67dt / 24f of rayon fiber are alternately beaten and weaved into 3 / 1 warp satin weave.

[0174]Put the woven gray fabric into a liquid flow dyeing machine, refine it at 80°C for 20 minutes, drain it, and then treat it with alkali at 50°C for 25 minutes with a concentration of 50g / L of sodium hydroxide. Next, only the ester side was dyed at 130°C. Since the dyed fabric became uneven, it was dried using a short-ring dryer, stretched with a pin tenter until the wrinkles of the knitted fabric could be removed, and set at 180° C. for 60 seconds. In addition, a water-absorbing agent is used for this finishing and setting.

[0175] The rayon fibers of the obtained fabric were drawn out, and the water absorption elongation was measured to be +9.3%.

[0176] In addition, the obtained fabric was subjected to a comfortable wearing test during exe...

Abstract

It is intended to provide a fabric which is comfortable for a wearer and shows neither stickiness nor stuffiness in sweating. The above object can be achieved by a cellulose fiber blended fabric characterized by containing cellulose fiber having a dimensional change rate upon water absorption of 2% or above. When employed in sport wears, inners, outers and so on, this fabric can give comfortableness to wears.

Description

technical field [0001] The present invention relates to a fabric mixed with special fibers whose dimensions change upon water absorption. More specifically, there is provided a fabric that is comfortable when worn and perspired by mixing cellulose-based fibers that change in size upon water absorption (self-expansion upon water absorption or self-shrinkage upon water absorption). Background technique [0002] In conventional clothes, the fabric absorbs sweat when sweating during sports or other activities, and the skin and the fabric are closely bonded, causing a so-called sticky or stuffy feeling. In order to prevent this phenomenon, various fabrics have been developed, but the improvement of comfort during sweat absorption is limited only by the structure of the fabric. In order to relieve this sticky feeling and stuffy feeling, fabrics and clothes using fibers that self-extend when absorbing sweat (at the time of absorbing water) have been proposed. For example, clothes...
