Problems solved by technology

However, the dissolution rate of cellulose acetate in ionic liquids is relatively low, generally around 3%-15%, and relying solely on the plasticizing effect of ionic liquids cannot make the strength of a high-proportion blend of cellulose acetate blends reach a satisfactory level.

Embodiment 1

[0024] Get ramie fiber powder, cellulose acetate powder, the pulverizing particle size of above powder is less than 300 orders;

[0025] Put the above powder into 1-butyl-3-methylimidazolium chloride ionic liquid ([BMIM)Cl), in which ramie fiber powder, cellulose acetate powder and 1-butyl-3-methylimidazolium chloride ionic liquid The mass parts of the three are: 2.5 parts of ramie fiber powder, 11 parts of cellulose acetate powder, 100 parts of 1-butyl-3-methylimidazolium chloride ionic liquid; Put it under the environment for 20-30 hours to obtain the spinning solution; after filtering and defoaming the spinning solution, perform electrostatic spinning under the action of 15-20KV voltage; then, carry out water bath under the condition of 10-15 degrees Celsius, bleach and dry After drying it forms acetate fibers blended with ramie fibers. Through the above treatment, the cellulose acetate monomer plasticized with the imidazole ionic liquid is formed, and the natural ramie pl...

Embodiment 2

[0031] Nylon powder and cellulose acetate powder are taken, and the pulverized particle size of the above powders is less than 300 mesh;

[0032] Put the above powder into chlorinated-allyl-methylimidazole hydrochloride ionic liquid ([AMIM)Cl), wherein the mass of nylon powder, cellulose acetate powder and chlorinated-allyl-methylimidazole hydrochloric acid ionic liquid The parts are: 2.5 parts of nylon powder, 10 parts of cellulose acetate powder, 90 parts of 1-butyl-3-methylimidazolium chloride ionic liquid; hours, to obtain the spinning solution; after the spinning solution is filtered and defoamed, it is electrostatically sprayed under the action of 15-20KV voltage; Rinse with 50% ethanol and dry to form acetate blended with nylon. Through the above treatment, a cellulose acetate monomer plasticized with imidazole ionic liquid is formed, and a synthetic nylon fiber component for improving strength and toughness is added therein.

[0033] Take the above-mentioned cellulose ...

Abstract

The invention provides a blended material with high acetate fiber content and a preparation method of the blended material. According to the invention, on one hand, the strength of acetate fiber per se is improved, and the crack resistance is improved; on the other hand, the clothing material obtained after blending is subjected to surface strengthening treatment, the stretch resistance, tear resistance and abrasion resistance are further improved, and the wet strength of the material is obviously improved. Through the treatment, the weakness that the mechanical strength of the acetate fiber is poor is eliminated, so that the content of the acetate fiber component in the blended material can be increased, and the excellent wearing properties of excellent touch, good air permeability, no static electricity and easiness in coloring of the acetate fiber can be reserved in the blended material to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a blended material with high content of acetate fiber and a preparation method thereof. Background technique [0002] Acetate fiber is a kind of chemical fiber clothing material made from cellulose acetate through spinning process. Acetate fiber can produce a soft, smooth, almost silky touch, good air permeability, no static electricity, easy to color and stable after coloring, so it has excellent ingestibility. Moreover, the energy consumption and water consumption of cellulose acetate production are low, the pollution is small, and the comprehensive benefits are remarkable. [0003] In the traditional application mode, acetate fiber can be used as the inner lining of clothing, so as to take advantage of its good touch when worn next to the skin, and acetate fiber can also be used for blending with real silk. It is worth noting that in recent years, the application range of a...
