Sericin post-finishing method for cotton fabrics

Abstract

The invention discloses a sericin post-finishing method for cotton fabrics, which comprises the following steps: (a) configuring settling impregnation liquid: dissolving 3-5% of dissolvable sericin powder counted by mass in hot water, and then adding 1-3% of chitosan quaternary ammonium salt, fully stirring and dissolving, and adding 4-6% of cross-linking agent, and (b) completely steeping the cotton fabrics in the settling impregnation liquid at a solution bath ratio of 1:(30-50), steeping for at least 20 minutes, twice steeping and twice rolling, keeping mangle expression more than 80%, anddrying, thereby obtaining the cotton fabrics. The invention develops the post-finishing method special for the cotton fabrics. The cotton fabrics prepared according to the post-finishing method have better washing fastness and anti-bacteria rate; after the cotton fabrics are washed for five times, a dissolving loss rate is about 0.21% and the anti-bacteria rate is 93.8%; the practical use requirement is fully met; and an extraordinary technical effect is obtained.

Description

technical field

[0001] The invention relates to a sericin post-finishing method for cotton fabrics. Background technique

[0002] The main body of silk fiber is silk fibroin, and sericin is coated on the periphery of silk fibroin, and sericin plays a protective and adhesive role on silk fibroin. Sericin is a biomaterial with excellent performance, which provides an extremely important application material for the development of new functional biomaterials. For example, sericin can be used as an additive for synthetic polymer materials. The physical properties of the resulting polymer materials can not only be improved, but also the polymer materials can be rapidly degraded by microorganisms and become excellent environmental protection materials; the mixture of sericin and silk fibroin The composed silk protein film will be a promising artificial skin. With the research on the structure and performance of sericin by scholars at home and abroad, sericin has been widely used...

Embodiment 1

[0024] A sericin post-finishing method for cotton fabrics, comprising the steps of:

[0025] (a) Configure impregnating solution: by mass, dissolve 5% of soluble sericin powder in hot water, then add 2% of chitosan quaternary ammonium salt, stir and dissolve fully, then add 5% of sericin powder joint agent;

[0026] The average molecular weight of the easily soluble sericin powder is 25000D; the temperature of the hot water is 90°C; the crosslinking agent includes a dispersant sodium polyacrylate and a silane coupling agent, and the mass ratio of the two is 3.0:4; The silane coupling agent is selected from vinylsilane, aminosilane, methacryloxysilane, mercaptosilane or ureidosilane;

[0027] (b) Completely immerse the cotton fabric in the above-mentioned finishing impregnation solution, the bath ratio of the solution is 1:40, immerse for at least 20 minutes, double dipping and two rolling, the liquid rolling rate is greater than 80%, and dry to obtain the cotton fabric.
