Problems solved by technology

The physical method is to improve the wrinkle resistance by changing the fabric structure, weaving method, etc., but the wrinkle resistance effect of silk fabrics is not obvious by this method
The chemical method is to use 2D resin, glyoxal, BTCA and chitosan as finishing agents for anti-wrinkle finishing. This method has good and long-lasting effects, but the mechanical strength of silk fabrics is greatly lost, and some finishing agents will release Harmful substances such as formaldehyde are harmful to the environment and human health

Abstract

The invention discloses a method of utilizing transglutaminase to improve crease resistance of silk fabric. The method comprises the following steps: utilizing a silk peptide and transglutaminase combined ultrasonic technology to process the silk fabric to improve the crease resistance of the silk fabric. The production method comprises the following steps: hydrolyzing the waste silk in a phosphoric acid solution to obtain silk peptide, soaking the silk in a silk peptide solution, conducting ultrasonic treatment, conducting transglutaminase processing, washing the fabric with water, drying the fabric to obtain the silk fabric after crease resistance treatment. The crease resistance treatment time is shortened by the ultrasonic treatment; the process is simplified; based on the step of soaking the silk fabric in the silk peptide solution, the transglutaminase treatment is conducted to enable silk protein to be crosslinked; the crosslinking between the protein and the amino acid strengthens the internal binding force of the silk, so as to improve the crease resistance of the silk fabric; furthermore, the original style and the wearability of the silk fabric can be kept; the loss of mechanical strength is low, and the silk fabric is ecologic and environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, in particular to a method for improving the anti-wrinkle performance of silk fabrics by transglutaminase. Background technique: [0002] Silk fabric has excellent characteristics such as lightness and elegance, smooth hand feeling, soft luster, moisture absorption and breathability, lightness and elegance, and health care functions. It is known as the "Fiber Queen". , easy to be damaged, and not easy to recover, so the dimensional stability of silk fabrics is poor, and it is easy to wrinkle during wearing or after washing, which affects the wearing performance. [0003] The fibers of silk fabric will be deformed under the action of external force. Since the binding force between silk protein molecules is weak and easy to break, the basic structural unit of silk will undergo relative displacement after breaking to form new hydrogen bonds, and it will not return to the original when the ...
