Soybean quilt is a quilt made of soybean protein fiber. Soybean protein fiber is a kind of protein spinning solution with a certain concentration, which is prepared by extracting globulin from soybean meal by bioengineering technology, adding functional additives, grafting, * * polymerization and * * mixing with high polymers such as nitrile group and hydroxyl group, changing the spatial structure of protein and wet spinning.
Soybean protein fiber is a kind of regenerated plant protein fiber. Using food-grade soybean protein powder (soybean meal) as raw material, the globulin in protein powder was extracted by bioengineering technology. By adding functional additives, grafting, * * polymerization and * * mixing with high polymers such as nitrile group and hydroxyl group, protein spinning solution with a certain concentration is made, and it is obtained by changing the spatial structure of protein and wet spinning.
It has a soft feel like cashmere and a soft luster like silk, and its warmth retention and skin friendliness are better than cotton. Known as "healthy and comfortable fiber in the new century" and "good fabric that skin likes".
Technical principle of soybean quilt production;
The fiber-forming polymer is dissolved in an appropriate solvent to obtain a solution with a certain composition, viscosity and good spinnability, which is called spinning dope. Spinning dope can also be obtained directly by homogeneous solution polymerization. The polymer swells before dissolving, that is, the solvent penetrates into the polymer first, so that the distance between macromolecules increases continuously, and then dissolves to form a uniform solution.
The speed of swelling process has an important influence on the dissolution rate. Before spinning, polymer solution must go through pre-spinning preparation procedures such as mixing, filtering and defoaming, so as to make the performance of spinning dope uniform, remove gel blocks and impurities entrained in it, and remove bubbles in the solution. In the production of viscose fiber, the preparation before spinning also includes the ripening process, so that viscose has the necessary spinnability.
