Embodiment 1

[0039] Take the gray skins from the tannery that are peeled evenly and discard the skins. After weighing and measuring, put them in a drum, wash them with 4 times warm water at 35°C for 2 times, each time for 20 minutes, drain the water and wash them with running water. 10 minutes; then add 1 times warm water at 30°C, 2% ammonium sulfate and 0.5% surfactant fatty alcohol ethylene oxide condensate, rotate for 60 minutes, and discharge the water in the drum; then use 38 Wash with warm water at ℃ until the pH of the peel is 7-8, then wash with hot water at 40°C for 10 minutes; add 1 times the hot water at 40°C and 1398 neutral protease with 0.1% of the weight of the peel, and rotate for 1.5 hours Finally, wash with flowing water and control dry; transfer the cleaned peel to a reaction kettle with a stirring device, add 2 times of water, gradually raise the temperature to 70°C, and keep it warm for 3 hours to fully dissolve the peel, and then After filtering, the filtrate was take...

Embodiment 2

[0042] Take the leather shaved from the tannery's blue wet shaved evenly, after weighing and measuring, put it in the drum, wash it with 4 times the warm water of 35 ℃ for 2 times, each time for 20 minutes, drain the water and then wash it with running water for 10 minutes. After 10 minutes, control the dryness, transfer the washed leather to the reaction kettle, add water 7 times the weight of the leather and calcium hydroxide of 3% of the weight of the leather, gradually heat up to 95 ° C, and keep it warm for 5 hours to make the leather Fully dissolve, then filter, neutralize the pH value to about 7.0 with diluted sulfuric acid solution, filter to remove calcium sulfate precipitate, and concentrate the filtrate to a concentration of 20%, then adjust the pH value to 5.5 with 1N sulfuric acid, and set aside.

[0043] Add the washed polyvinyl alcohol with a degree of polymerization of 1700 and a degree of alcoholysis of 99% into water, heat and stir until dissolved at 98°C for ...

Abstract

The invention relates to a metal ion modified collagen protein-polyvinyl alcohol composite fibre. On the basis containing collagen protein and polyvinyl alcohol it also contains metal ions capable of producing chelation crosslinking action. Said invention also relates the preparation method of said composite fibre, and said method includes the following steps: adding metal salt into the collagen protein-polyvinyl alcohol mixed solution to make chelation crosslinking modification to obtain spinning solution, and adopting a series of after processes so as to obtain the new type collagen protein-polyvinyl alcohol composite fibre.

Description

1. Technical field [0001] The invention belongs to the technical field of collagen-polyvinyl alcohol composite fibers, and specifically relates to a collagen-polyvinyl alcohol composite fiber modified by metal ions and a manufacturing method thereof. 2. Background technology [0002] Textile fibers can usually be divided into natural fibers and synthetic fibers. Natural fibers include cotton, linen, silk, wool, etc., and synthetic fibers include polyester, acrylic, polypropylene, vinylon, etc. [0003] Compared with natural fibers, synthetic fibers have huge advantages in terms of output and strength, but because of their poor hygroscopicity and air permeability, their wearing comfort is far inferior to natural fibers, and acetalized polyvinyl alcohol fibers, namely vinylon, still exist. Due to the disadvantage of poor dyeability, vinylon is mainly used in industrial products and is greatly limited in civilian products. Therefore, it is very necessary to modify vinylon. [...
