Problems solved by technology

However, chitosan fiber has poor mechanical properties and is not suitable for direct processing, which makes it difficult to prepare antibacterial fabrics by weaving chitosan fiber; in addition, due to the small friction coefficient of chitosan fiber surface, The fiber cohesion is low, so the hairiness increases greatly in the winding process, which may easily cause the problem of poor yarn forming effect

Abstract

The invention relates to an antibacterial functional cationic polyester blended fabric and a preparation process thereof. The preparation process includes the step of weaving antibacterial functionalcationic polyester blended yarn to obtain the antibacterial functional cationic polyester blended fabric. The antibacterial functional cationic polyester blended yarn is prepared by carding cationic polyester fibers obtained after plasma treatment, cotton fibers and chitosan fibers separately, carrying out mixing, and then sequentially carrying out the procedures of drawing, roving, spinning and winding, wherein according to the parameters of the winding procedure, the winding speed is 850-1200 m / min, and the tension is 5-8 cN; the finally prepared antibacterial functional cationic polyester blended fabric is excellent in elasticity, soft and comfortable in hand feeling and good in moisture absorption and air permeability. The blended fabric solves the problems that cationic polyester fibers are poor in antibacterial property, chitosan fibers are low in breaking strength, high in rigidity and low in cohesive force, and thus the spinnability is poor. The obtained fabric has good antibacterial function, great mechanical performance, high moisture absorption and air permeability and low hairiness number.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to an antibacterial functional cationic polyester blended fabric and a preparation process thereof. Background technique [0002] Cationic polyester, also known as cationic dye-dyeable polyester, is a modified polyester product. Modification of polyester can improve the color absorption performance of the fiber and reduce the crystallinity of the fiber, making the dye molecules easy to penetrate, facilitating the dyeing of the dye molecules, and the fiber absorbs moisture. The air permeability is also further improved, so the development and application of cationic polyester is very extensive. [0003] When developing and applying polyester, it is often necessary to modify polyester. The cationic polyester obtained after modification is dyed with cationic dyes. The dyed fabric is bright in color, has a high dye exhaustion rate, and greatly reduces the discharge of printing and dyeing...
