Problems solved by technology

However, if the moisture absorption of the fiber reaches saturation, the moisture absorption and heating fiber will not generate heat again, not only the heating time is shorter, but also after the moisture absorption reaches saturation, it will feel cold due to the moisture in the fiber
Moreover, as heat-generating fabrics and heat-generating clothing other than moisture-absorbing heat, it is known to install heaters such as planar heating elements and linear heating elements on clothing, etc., but since they all use electricity to generate heat, when making clothing, Clothing becomes heavy and difficult to move due to the need for electrodes
[0003] Like this, at present, in the clothes that the temperature rises when wearing, besides moisture absorption and heat generation, easy-to-operate and lighter clothes have not been found. Discover garments that continue to generate heat when worn as garments, and are lightweight and easy to move

Embodiment 1

[0150]Using a 32-gauge tricot machine, prepare elastic yarn 44dtex (trade name ROICACR: manufactured by Asahi Kasei Fiber Co., Ltd.) on the rear bar, and prepare nylon raw yarn 22dtex∕7f on the front bar, in the following weave , compiled under the conditions.

[0151] Front bar 10∕23

[0152] Rear comb 23∕10

[0153] The knitted fabric after knitting is relaxed and refined using a continuous refining machine (Japanese: 连続素油机), followed by presetting, that is, adjusting the width and length at 190°C for 1 minute so that the density is approximately the same as that of the gray fabric , and then, the nylon is dyed using a liquid flow dyeing machine. Fill in softening agent after dyeing, arrange and set at 170 ℃ for 1 minute with the same density as pre-setting, and make knitted fabric.

[0154] The obtained knitted fabric is a special organization, and the blending ratio of the elastic yarn is 44%, which is higher than that of the usual tricot warp knitted fabric. In additio...

[0155] Example 2 to Example 5, Comparative Example 1

[0156] Change the fineness of the elastic yarn to 33dtex (trade name ROICA SF: manufactured by Asahi Kasei Fiber Co., Ltd.) (Example 2), change the fineness of the elastic yarn to 33dtex, and change the structure of the rear bar to 20 / 13 (implementation Example 3) In addition, the fineness of the elastic yarn was changed to 22dtex (trade name ROICA SF: manufactured by Asahi Kasei Fiber Co., Ltd.), and the structure of the rear bar was changed to 12 / 10 (comparative example 1), in addition , A knitted fabric was produced in the same manner as in Example 1, and evaluated. The results are shown in Table 1.

[0157] In addition, the polyurethane polymer (A agent) used in Example 4 of JP 7-316922 A and the polyurethane urea compound (B agent) used in Example 1 of JP 2001-140127 A were prepared, Add 7wt% A agent and 3wt% B agent (Example 4) to the spinning bath when manufacturing elastic yarn 44dtex (trade name ROICA CR: Asah...

[0160] Using a 32-gauge tricot machine, prepare stretch yarn 33dtex (trade name ROICA SF: manufactured by Asahi Kasei Fiber Co., Ltd.) on the rear bar and prepare stretch yarn 33dtex (trade name ROICA SF: Asahi Kasei Co., Ltd.) on the middle bar. Fiber (manufactured by Co., Ltd.), prepare nylon raw yarn 33dtex / 34f in the front bar, and weave it with the following weave.

[0161] Front bar 10∕23

[0162] Middle comb 10∕01

[0164] The knitted fabric after knitting is relaxed and refined by a continuous refining machine, and then pre-set, that is, the width and length are adjusted at 190°C for 1 minute to make the density approximately the same as that of the gray fabric, and then dyed by liquid flow machine for dyeing nylon. Fill in softening agent after dyeing, arrange and set the shape for 1 minute under the condition of 170 ℃, and make knitted fabric.

[0165] The performance of the obtained knitted fabric was evaluated, and the results are shown...

Abstract

The present invention pertains to a stretch knitted fabric which exhibits an instantaneous temperature rise when stretched and which, by the repetition of stretching and relaxation, lastingly generates heat when stretched. A stretch knitted fabric which is composed of a non-elastic yarn and an elastic yarn, characterized in that the instantaneous temperature rise caused by heat generation at 100% warpwise and / or weftwise stretching is 1.0 DEG C or more.

Description

technical field [0001] The present invention provides a stretchable knitted fabric in which the temperature rises instantaneously when stretched in a fabric containing elastic yarn, and warm clothing using the knitted fabric. Background technique [0002] In the past, as heat-retaining clothes and other clothes whose temperature rises when worn, there is known a kind of clothes made of cloth mixed with moisture-absorbing and heat-generating fibers such as cellulose, and clothes that generate heat by using non-sensing evaporation and sweating from the human body when worn ( For example, refer to Patent Document 1). However, if the moisture absorption of the fiber reaches saturation, the moisture absorption and heating fiber will not generate heat again, not only the heating time is shorter, but also after the moisture absorption reaches saturation, the fiber will feel cold due to the moisture in the fiber. Moreover, as heat-generating fabrics and heat-generating clothing oth...
