Problems solved by technology

[0003] Silk fibroin fabric finishing is mostly mixed with silk fibroin solution and other functional agents as a finishing agent, and the fabric is finished by dipping, coating or spraying. In this finishing method, silk fibroin is mostly covered on the fabric in the form of a film. The surface of the fabric is not conducive to the feel and breathability of the fabric
Silk fibroin particles are one form of silk fibroin. The preparation methods of silk fibroin particles include emulsification solvent evaporation method, phase separation method, high-voltage electrostatic method and spray drying method, etc., but the silk particles prepared so far are all solid particles. Compared with solid particles, porous particles have better air and moisture permeability, adsorption performance and functionality, but there are not many studies on silk protein porous particles.

Abstract

The invention provides a tussah fibroin protein microsphere including a three-dimensional porous structure and a production method thereof. The method comprises the steps of using tussah silk as raw material, degumming the tussah silk, placing degummed tussah silk into solvent to dissolve completely, dialyzing, separating, adding enzyme solution for enzymolysis, heating, and concentrating to obtain tussah fibroin protein solution; adding a foaming agent and a cross-linking agent into the tussah fibroin protein solution, standing, stirring and centrifugally separating to form tussah fibroin protein particles; and adding the tussah fibroin protein particles into sodium chloride solution, heating, stirring, centrifugally separating sediments, washing with ethyl alcohol, taking the washed sediments out, drying and placing into a low temperature environment to cool and dry, thus acquiring the tussah fibroin protein microspheres with three-dimensional porous structures. The production method provided by the invention is simple, and the produced silk fibers are good in porosity and have the properties of being skin-friendly, air and vapor permeable and adsorptive.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a tussah silk fibroin microsphere containing a three-dimensional hole structure and a preparation method thereof. Background technique [0002] Silk fibroin is an animal protein derived from silk fiber. Whether it is mulberry silk or tussah silk, silk fibroin is mainly composed of 18 kinds of amino acid tissues such as glycine, alanine and serine. Silk fibroin has good degradability, Biocompatibility and formability, etc., silk fibroin has many applications in fabric finishing. [0003] Silk fibroin fabric finishing is mostly mixed with silk fibroin solution and other functional agents as a finishing agent, and the fabric is finished by dipping, coating or spraying. In this finishing method, silk fibroin is mostly covered on the fabric in the form of a film. The surface of the fabric is not conducive to the feel and breathability of the fabric. Silk fibroi...
