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, ...

[0042] Raw material: moisture absorption and heat generation 40 / modal 60 32s knitting yarn

[0043] Hygroscopic and heating fiber / modal mixed box: the cotton box is mixed with the FA102A automatic plucking machine; the specific cotton catching machine is the FA002D automatic cotton catching machine; the cotton opener is specifically the FA104 six-roller opener; the lapping machine is specific It is the FA141A single-hand lapping machine; the carding machine is specifically the FA201B carding machine; the drawing frame is specifically the E32 type sliver and lap machine; It is A201E type combing machine.

[0044] Control the neps well before drawing, and use soft top rollers for drafting during spinning.

[0045] In the carding process, the tension of the cotton web is 1.37, and the tension of the roving spinning is 0.9 μN.

[0046]Twist factor: 310-330.

[0047] Yarn quality indicators: breaking strength: (15.3cN / tex); evenness: 13.5; blackboard neps: 23 grains / g.

Abstract

The invention relates to a method for spinning hygroscopic and heat-generating fibers, comprising: pre-treating hygroscopic and heat-absorbing fibers and cotton fibers respectively, and then drawing and mixing to obtain fabrics, wherein the blending ratio of cotton fibers and hygroscopic and heat-generating fibers is 90-60 : 10‑40, the count is 20s‑40s; or mix the hygroscopic heating fiber and the cellulose fiber in a cotton box to obtain a fabric; wherein the blending ratio of the hygroscopic heating fiber and the cellulose fiber is 20‑50:80‑50, the count The numbers are 20s‑40s. By improving the parameters of some steps in the spinning process, the invention compensates for the defects of the fiber itself (such as low fiber strength, low curl, high fiber linear density, high moisture regain, etc.), and achieves the purpose of improving the actual experience of the product.

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...
