Abstract

The invention discloses spinning milk protein fiber and a preparation method thereof and belongs to the technical field of textile. A prepared toughening additive better fixes active components in milk fiber, so that the milk fiber has better energy storage performance, besides, the mechanical performance of the milk fiber is improved, the tensile property is improved, the milk fiber cannot breakeasily during spinning, and the spinning effect is improved while original characteristics of the milk fiber are kept; by the aid of a prepared fixation film forming agent, dopamine is oxidized to form a film by self-polymerization in an oxygen environment, and a formed film structure facilitates fixation of dye; by the aid of a prepared anti-adhesion coating, during spinning of the spun yarn prepared from the milk fiber, adhesion to parts due to viscosity of the milk fiber is reduced by use of low surface performance of the milk fiber, and the phenomenon of flying during spinning can be avoided. The problems that fiber adheres to parts easily and the phenomenon of flying is serious during spinning of the milk fiber at present is solved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a spinning milk protein fiber and a preparation method thereof. Background technique [0002] With the continuous progress of society and the rapid development of science and technology, people's requirements for quality of life are constantly improving, and people are paying more and more attention to clothing that integrates comfort, health care, environmental protection, high-end and fashion. At present, using existing equipment, multifunctional fibers are used as raw materials, combined with new technologies to continuously improve the quality of fibers, and the preparation of multifunctional clothing products is favored by consumers. [0003] Milk fiber is a kind of regenerated protein fiber. It uses milk as the main raw material. After the milk is evaporated and concentrated to remove water, it is processed by degreasing and alkalization to obtain a fat-free emulsion, whic...
