Abstract

The invention relates to the field of weaving of textiles and discloses a water-absorbing composite silk fabric and a processing method thereof. The method includes steps: subjecting modified polyethylene glycol to mixed reaction with fibroin; spinning and twisting to obtain modified silk fibers; mixing spider silk protein liquid with glucan; spinning and twisting to obtain modified spider silk fibers; blending the obtained modified silk fibers with the modified spider silk fibers to obtain a water-absorbing composite silk gray fabric; subjecting the water-absorbing composite silk gray fabricto mixed reaction with protease solution, performing high-temperature enzyme deactivation, adding chitosan mixed liquid, filtering after stirring reaction, and performing freeze drying to obtain the water-absorbing composite silk fabric. The water-absorbing composite silk fabric prepared according to the method is excellent in water absorbing performance and great in drapability.

Description

technical field [0001] The invention relates to the field of textile weaving, in particular to a water-absorbing composite silk fabric and a processing method thereof. Background technique [0002] Silk is woven from silk fiber as a raw material. Silk fiber is a kind of protein fiber, known as the "fiber queen" and the "national treasure" of our country. Silk fibroin in silk contains 18 kinds of amino acids that are of great nutritional value to the human body, so silk fabrics have a good affinity for human skin, and it has the reputation of "human second skin". The cross-section of silk fiber is triangular, the longitudinal direction is smooth and flat, and it has a layered structure, which makes it have better luster than other fibers. The silk fineness is finer and its moisture absorption capacity is better. In addition, silk also has a strong anti-ultraviolet function and a silky sound that other fibers do not have. The characteristics of silk fiber endow silk fabrics ...
