Problems solved by technology

[0005] At present, the method of high moisture absorption and heating clothing on the market is mainly through the combination and blending of acrylic fibers, viscose and other fibers to achieve the effect of heating: viscose, as a cellulose fiber with a high moisture regain, can absorb water quickly and emit a small amount of moisture. Heat; acrylic fiber is close to wool in terms of warmth retention and bulkiness, and has a certain heat preservation effect, but its actual heat retention effect is unstable
In addition, high moisture absorption and heating fibers with graft copolymerization structure are currently mainly imported from Japan, which are expensive and have limitations in the application of final products

Embodiment 1

[0035] A high moisture absorption heating yarn, the yarn is grafted modified high moisture absorption fiber after pretreatment, and then blended with viscose fiber in a weight ratio of 15:85 to obtain the yarn, its structure is as follows figure 1As shown, the grafted modified high moisture absorption fiber is a high moisture absorption polyacrylonitrile fiber, and -OH, -NH are introduced into the polyacrylonitrile side chain 3 , -COOH and -CONH and other hydrophilic groups make the fiber have good temperature and humidity regulation functions. This example uses Yirebao high moisture absorption modified polyacrylonitrile produced by Shanghai Zhengjia Milk Silk Technology Co., Ltd. fiber. The pretreatment is to spray 0.5wt% antistatic agent on the surface of the grafted modified high moisture absorption fiber, and then let it stand for 8 hours.

[0036] Blending uses the following steps:

[0037] (1) Blowing and carding unit: Unpack the packaged fiber and put it into the cott...

Embodiment 2

[0045] A high moisture absorption heating yarn, the yarn is grafted modified high moisture absorption fiber after pretreatment, and then blended with cotton fiber in a weight ratio of 20:80 to obtain the yarn, its structure is as follows: figure 1 As shown, the grafted modified high moisture absorption fiber is a high moisture absorption polyacrylonitrile fiber, and -OH, -NH are introduced into the polyacrylonitrile side chain 3 , -COOH and -CONH and other hydrophilic groups make the fiber have good temperature and humidity regulation functions. This example uses Yirebao high moisture absorption modified polyacrylonitrile produced by Shanghai Zhengjia Milk Silk Technology Co., Ltd. fiber. The pretreatment is to spray 0.5wt% antistatic agent on the surface of the grafted modified high moisture absorption fiber, and then let it stand for 8 hours.

Abstract

The invention relates to a high-moisture-absorption heating yarn and application thereof. The yarn is formed in the manner that graft-modified high-moisture-absorption fibers are pre-treated, and thenthe graft-modified high-moisture-absorption fibers are blended with viscose or cotton fibers or modal fibers or acrylic fibers. The high-moisture-absorption heating yarn is prepared through the preparation process which includes the steps of blowing-carding, combing, drawing, roving, spinning, spooling and the like. Two high-moisture-absorption heating yarns are twisted to form a plied yarn. Compared with the prior art, the high-moisture-absorption heating yarn has the advantages of rapid moisture absorption heating and the like, and the comfort of manufactured fabric is further improved.

Description

technical field [0001] The invention relates to a yarn and a strand, in particular to a yarn with high moisture absorption and heat generation and its application. Background technique [0002] In recent years, with the improvement of people's living standards, the requirements for the comfort and functionality of clothing or clothing fabrics have become higher and higher. The comfort of clothing is closely related to the moisture absorption and release properties of materials. Therefore, more and more attention is paid to the research and development of water-absorbing and sweat-absorbing fibers at home and abroad. [0003] In daily life, when ordinary close-fitting clothes are first put on, the human body feels cold. Just sleeping in a chemical fiber quilt, it feels colder than cotton quilts and wool quilts. Because of the temperature difference between the skin and the clothes, heat conduction occurs, often Covering your body with warm clothes is distressing and uncomfor...
