preparation example Construction

[0018] The preparation method of colored protein viscose fiber of the present invention, it comprises the steps:

[0019] A. Degrease, decolorize and deodorize animal and vegetable protein raw materials to obtain animal and vegetable protein powder;

[0020] B. Alkalinization: Dissolve animal and vegetable protein powder in lye to obtain protein alkali solution;

[0021] C, adding a cross-linking agent in the protein alkali solution to obtain a protein spinning solution;

[0022] D. Blending of protein spinning solution and dyed viscose, or blending of protein spinning solution and viscose, dyeing and spinning to obtain protein filaments;

[0023] E. Wash the protein silk with peroxide solution, oil it, dry it, and form it into a tube to obtain colored protein viscose fiber.

[0024] In the above method, the following types of animal and vegetable proteins can be used, such as animal protein is at least one of milk protein, silkworm chrysalis protein, animal fur protein or i...

Abstract

The invention relates to a colored protein viscose fiber and a preparation method thereof, belonging to the textile field and aiming at providing an equal-coloring colored protein viscose fiber preparation method. The preparation method of the invention includes the following steps: 1. animal and plant proteins are degreased, decolored and deodorized to obtain animal-plant protein powder; 2. alkalization: the animal-plant protein powder is dissolved in alkaline liquor to obtain protein alkaline solution; 3. cross-linker is added into the protein alkaline solution to obtain protein spinning liquor; 4. the protein spinning liquor is blended with a coloring glue to be spun to obtain protein filaments. 5. the protein filaments are washed by peroxide solution and are oiled, dried and formed into cylinder form to obtain the colored protein viscose fiber. The colored protein viscose fiber of the invention has equal-coloring process, high color fastness and color brightness, and the preparation method does not adopt any acetalation treatments to the protein filaments after spinning so as to avoid the remaining of methanal, etc. harmful matters, the technique steps are simple and can be easily operated and the manufacturing can be realized with the existing viscose fiber preparation equipment.

Description

technical field [0001] The invention relates to colored protein viscose fiber and a preparation method thereof, belonging to the textile field. Background technique [0002] Protein fiber is a kind of composite fiber material obtained by blending or grafting copolymerization of animal and vegetable protein and fiber raw materials, and then post-processing. Commonly used animal proteins include: milk protein, silkworm chrysalis protein, etc.; vegetable proteins include soybean protein, peanut protein, corn protein, etc.; fiber raw materials include polyvinyl alcohol, polyacrylonitrile, and regenerated cellulose. [0003] The protein in the protein fiber contains a variety of amino acids. The protein fiber has the function of skin care and health care. It is suitable for making underwear and is comfortable to wear. It is very popular among consumers. [0004] Animal and vegetable protein raw materials are processed through degreasing, decolorization, deodorization and other p...
