Embodiment 1

[0029] Embodiment 1 A kind of acid-base interlaced imitation cashmere acrylic yarn

[0030] The acid-base interlaced imitation cashmere acrylic yarn is obtained by spinning the following raw materials and their mass percentages: 5% acid-dyeable polyacrylonitrile fiber, 20% high-shrinkage acrylic fiber, and 75% conventional acrylic fiber; the conventional acrylic fiber is selected from cotton fiber. The relative humidity of each raw material is 50, and the temperature is 20°C.

[0031] The preparation method of the acid-dyeable polyacrylonitrile fiber is as follows: acrylonitrile monomer and acrylic acid amino ester are mixed in a mass ratio of 0.5:3, deionized water is added, initiator potassium persulfate is protected by nitrogen, and polymerized at 60°C for 5 hours , wash with acetone, water and mass fraction in turn with 20% NaSCN aqueous solution, and dry to obtain AN / TAM copolymer; AN / TAM copolymer and polyacrylonitrile are mixed in a mass ratio of 6.5:94, and the concen...

Embodiment 2

[0042] Embodiment 2 A kind of acid-base interlaced imitation cashmere acrylic yarn

[0043] The acid-base interlaced imitation cashmere acrylic yarn is obtained by spinning the following raw materials and their mass percentages: 40% acid-dyeable polyacrylonitrile fiber, 40% high-shrinkage acrylic fiber, and 20% conventional acrylic fiber; the conventional acrylic fiber is selected from cotton fiber. The relative humidity of above-mentioned raw material is 80, and temperature is 30.

[0044] The preparation method of the acid dyeable polyacrylonitrile fiber is: carry out the copolymerization reaction of acrylonitrile monomer and acrylic acid amino ester according to the mass ratio of 2:5, obtain AN / TAM copolymer; combine AN / TAM copolymer and polyacrylonitrile Mix by mass ratio 7:80, other steps are with the preparation method described in Example 1.

[0045] The spinning process of the cashmere-like acrylic yarn with acid-base pattern is the same as that described in Example ...

Embodiment 3

[0046] Embodiment 3 A kind of acid-base interlaced imitation cashmere acrylic yarn

[0047] The cashmere-like acrylic yarn with acid-base interlaced patterns is obtained by spinning the following raw materials and their mass percentages: 10% of acid-dyeable polyacrylonitrile fiber, 40% of high-shrinkage acrylic fiber, and 50% of conventional acrylic fiber. The conventional acrylic fibers are polyester fibers. The relative humidity of above-mentioned raw material is 60, and temperature is 23.

[0048] The preparation method of the acid dyeable polyacrylonitrile fiber is as described in Example 2.

[0049] The spinning process of the cashmere-like acrylic yarn with acid-base pattern is the same as that described in Example 1.

Abstract

The invention belongs to the technical field of spinning and relates to an acid-base fancy cashmere-like acrylic yarn and a spinning process thereof. The acid-base fancy cashmere-like acrylic yarn isobtained by spinning the following raw materials, in percentage by mass, of 5-40% of acid dyeable polyacrylonitrile fibers, 20-40% of high-shrinkage acrylic fibers and 20-75% of conventional acrylic fibers; and the conventional acrylic fibers are selected from one of cotton fibers, polyester fibers or common acrylic fibers. The spinning process comprises the following processes of weighing, mixing, carding, drawing, roving, spinning, automatic winding, doubling and double twisting. The acid-base fancy cashmere-like acrylic yarn has the advantages of fluffy and soft appearance, good yarn rebound resilience, strong antistatic capability, higher breaking strength, high dyeing uniformity, suitability for dyeing various fancy colors and wide yarn application. The spinning process is simple, thedyeing procedure is shortened, and the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a cashmere imitation acrylic fiber yarn with acid-base interlaced patterns and a spinning process thereof. Background technique [0002] In the production of mixed-color textiles, if the surface of the mixed-color fabric has a similar color and is relatively the same color, it is customarily called a "plain color" effect; It is customary to call it the "flower clip" effect. [0003] Since the 1990s, with the development of domestic spinning technology, a breakthrough has been made in the technology of spinning expanded acrylic fibers of 64mm and above with cotton spinning equipment. Ordinary acrylic natural yarns are dyed with cationic dyes to produce bright colored yarns of various colors; with the diversification of market demand, interlocking colors have become one of the mainstreams in the market, and the demand for interlaced acrylics is gradually increasing. And the weavin...
