Embodiment 1

[0026] Take 32s JC 90 / moisture-absorbing and heating fiber 10 smooth yarn for knitting as an example:

[0027] Raw materials: 1. Hygroscopic and heating fiber: 10%, 2.78dtex*38mm;

[0028] 2. JC: 90%, grade 2.2, main body length 29mm.

[0029] Routing:

[0030] Hygroscopic heating fiber:

[0031] It goes through plucking machine, cotton opener, lapping machine, carding machine, and pre-merging in sequence. The catching machine is specifically the FA002D automatic catching machine; the cotton opener is specifically the FA104 six-roller opener; the lapping machine is specifically the FA141A single-hand lapping machine; the carding machine is specifically the FA201B carding machine; Pre-and specifically for the FA306 draw frame.

[0032] During the pre-spinning and cleaning process, comb needles are used in the blower form, and the beater speed is 940r / min.

[0033] During the carding process, the card clothing is selected according to the principle of short, shallow, thin, ...

Abstract

The invention relates to a spinning method of moisture-absorbing and heating fibers. The method comprises the steps of preprocessing the moisture-absorbing and heating fibers and cotton fibers respectively, and adopting a drawing blending mode to obtain fabric, wherein the blending ratio of the cotton fibers to the moisture-absorbing and heating fibers is (90-60):(10-40), and the count is 20-40 s;or conducting hopper blending on cellulose fibers and the moisture-absorbing and heating fibers to obtain fabric, wherein the blending ratio of the moisture-absorbing and heating fibers to the cellulose fibers is (20-50):(80-50), and the count is 20-40 s. According to the spinning method of the moisture-absorbing and heating fibers, by improving the parameters of some steps in the spinning process, the defects of the fibers are overcome that the fiber strength and the crimpness are low, the fiber line density is high, and the moisture regain is too high, and the purpose of improving the actual experience effect of products is achieved.

Description

technical field [0001] The invention belongs to the field of fiber spinning methods, in particular to a spinning method for moisture-absorbing and heating fibers. Background technique [0002] The scientific name of this moisture-absorbing and heating fiber is: modified polyacrylonitrile fiber, which is a new structure of polymer fiber material. It uses acrylic fiber as the matrix and introduces a large number of hydrophilic groups such as -OH, -NH3, -COOH, -CONH into the molecular chain. group. Hygroscopic and heating fiber is one of the key products of high-tech fiber. Hygroscopic heating fiber is a fiber material that can generate heat by itself after absorbing water. Its heating effect is to use the moisture produced by absorbing the skin of the human body to achieve the effect of heating, which can prevent the human body from feeling cold after sweating. In addition, the high hydrophilic group of the fiber makes the fiber have the function of balancing pH value and e...
