Example Embodiment
[0034] Example 1
[0035] A high-hygroscopic heating yarn, which is a yarn obtained by grafting modified high-hygroscopic fiber through pretreatment and then blending with viscose fiber at a weight ratio of 15:85. The structure is as follows figure 1 As shown, the grafted modified high moisture absorption fiber is a high moisture absorption polyacrylonitrile fiber, and -OH and -NH are introduced into the side chain of the polyacrylonitrile 3 Hydrophilic groups such as, -COOH and -CONH make the fiber have a good temperature and humidity adjustment function. This example uses the Yirebao high moisture absorption modified polyacrylonitrile produced by Shanghai Zhengjia Milk Silk Technology Co., Ltd. fiber. The pretreatment is to spray 0.5wt% of an antistatic agent on the surface of the grafted modified high-hygroscopic fiber, and then stand for 8 hours.
[0036] The blending uses the following steps:
[0037] (1) Blowing and carding: unpack the packed fibers and put them into the cotto...

[0044] Example 2
[0045] A high-hygroscopic heating yarn, which is a yarn obtained by grafting modified high-hygroscopic fiber through pretreatment and then blending with cotton fiber at a weight ratio of 20:80. The structure is as follows figure 1 As shown, the grafted modified high moisture absorption fiber is a high moisture absorption polyacrylonitrile fiber, and -OH and -NH are introduced into the side chain of the polyacrylonitrile 3 Hydrophilic groups such as, -COOH and -CONH make the fiber have a good temperature and humidity adjustment function.
