Problems solved by technology

In non-durable antibacterial finishing, while natural or chemical finishing agents impart antibacterial effects to silk floss products, they also have the disadvantages of not being firmly bonded to mulberry silk fibers, easily dissolving from the fiber surface, releasing or even migrating to the skin surface; When processing durable antibacterial silk cotton varieties, chemical cross-linking agents need to be added during dipping or baking, which not only easily leads to the problem of oxidative yellowing of silk cotton, but the residual chemical cross-linking agents will also affect the ecological safety of silk cotton

Abstract

The invention discloses a silk floss finishing method. The silk floss finishing method comprises the following steps of: A, preparing an amino-containing antibacterial agent finishing liquid, whereinthe amino-containing antibacterial agent comprises polylysine, chitosan with deacetylation exceeding 85% and chitosan quaternary ammonium salt with deacetylation exceeding 85% and substitution degreeof 60-90%, and dipping silk floss into the finishing liquid; B, adding laccase into the finishing liquid in the step A, and continuously dipping the silk floss subjected to dipping treatment in the step A; C, cleaning the silk floss treated in the step B in water; and D, drying the silk floss treated in the step C. The silk floss finishing method disclosed by the invention has the advantages thatby virtue of the laccase, the amino-containing antibacterial agent is grafted on the surface of silk floss fiber by catalysis, so that the silk floss product is endowed with antibacterial effect; andthe silk floss finishing method has the characteristics of safe treatment process and lower production energy consumption, and ecological functional processing of the silk floss product is realized.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a silk floss finishing method. Background technique [0002] Silk quilt is a high-grade home textile product, and its main filling is silk cotton made of mulberry silk. In the production and processing of silk, the cocoon-cooking treatment is first performed to remove the sericin component with a spherical structure in the outer layer of mulberry silk with hot water, alkaline solution or proteolytic hydrolysis, and the silk fibroin with high chemical stability is effectively obtained. reserve. The silk floss product obtained after cocoon peeling and flossing is not only soft to the touch, elegant in luster, but also has excellent mechanical properties and warmth retention. On the other hand, silk cotton is a protein-based fiber product. Under appropriate temperature and humidity conditions, it is easy to become nutrients for bacteria, molds and other microo...
