Preparation method for composite regenerated cellulose fibers

Abstract

The invention discloses a preparation method for composite regenerated cellulose fibers. The aniline monomer is first added into the regenerated cellulose solution. Then by adopting in-situ polymerization, polyaniline molecules are generated on the regenerated cellulose in the solution. Spinning solution is attained after filtration, vacuum degassing; polyaniline-regenerated cellulose composite fibers are attained after the spinning solution is sprayed through a spinneret hole, coagulated and shaped in coagulation bath, stretched, crimped, finalized and dried. The composite regenerated cellulose fibers are prepared by dipping the polyaniline-regenerated cellulose composite fibers in silver nitrate solution and then in glucose solution. The preparation method for the composite regenerated cellulose fibers has the advantages of good antibacterial effect, strong antibacterial persistence and high mechanical properties, which can effectively improve the comfort and functionality of textiles.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to a method for preparing composite regenerated cellulose fibers. Background technique [0002] With the continuous improvement of people's living standards, consumers have transformed from the initial pursuit of warmth and comfort to functional, safe and healthy consumption concepts, and the comfort and functionality of textiles have attracted more and more attention. Harmful microorganisms such as Escherichia coli and Staphylococcus aureus exist in every corner of people's lives, especially hydrophilic cellulose fibers are more susceptible to bacterial infestation, which seriously affects the hygiene of their clothing and poses a threat to human health Therefore, antibacterial cellulose fibers and textiles with functional functions of antibacterial or bactericidal, fungi or viruses and other harmful organisms have emerged as the times require. [0003] At present, the prod...

Problems solved by technology

Although nano-silver is insoluble in water and can delay the loss of antibacterial agents, on the one hand, the combination of nano-silver and fibers is not strong enough, and it is easy to fall off after repeated use, making it difficult to ensure long-term antibacterial performance. Aggregation occurs in the silk liquid, and its direct addition is likely to have a negative impact on the mechanical properties of the fiber
