Problems solved by technology

[0007] The methods and treatment reagents used for different fibers are quite different, and the products produced have defects such as poor spinnability, harmful substances such as formaldehyde, and low product strength. Formaldehyde will cause great harm to spinning workers, and because a large amount of formaldehyde and other substances will not completely react, it will produce a large amount of formaldehyde emissions, causing environmental pollution

preparation example Construction

[0020] The preparation method of protein viscose fiber of the present invention, it comprises the steps:

[0021] A. Degrease, decolorize and deodorize animal and vegetable protein raw materials to obtain animal and vegetable protein powder;

[0022] B. Alkalinization: Dissolve animal and vegetable protein powder in lye to obtain protein alkali solution;

[0023] C, adding a cross-linking agent in the protein alkali solution to obtain a protein spinning solution;

[0024] D, protein spinning solution is blended with viscose, and spun to obtain protein filaments;

[0025] E. Wash the protein silk with a peroxide solution, oil it, dry it, and form it into a tube to obtain the protein viscose fiber.

[0026] In the above method, the following types of animal and vegetable proteins can be used, such as animal protein is any one or more of milk protein, silkworm chrysalis protein, animal fur protein and insect protein; such as vegetable protein is any one of soybean protein and p...

Embodiment 1

[0033] Weigh 1 part of pupal protein powder, add 4 parts of 5% sodium hydroxide aqueous solution, stir and heat to 60° C., dissolve and defoam to obtain pupa protein alkaline solution. Add 5% polycarboxylic acid in pupal protein alkali solution to obtain pupa protein spinning solution, by pupa protein spinning solution and viscose 1 to 25 ratio, pupa protein spinning solution is added in the viscose, mix evenly, After filtering, spinning, the silk cake is washed with 3% sodium percarbonate aqueous solution, washed with water, oiled, dried, and formed into a tube to obtain pupal protein viscose fiber.

[0034] Product physical inspection indicators - color: light yellow-brown, bright; dry strength: 1.7~1.9cn / dtex; dry extension: 16~18%; dyeing grade: 4.0 grade.

Embodiment 2

[0036] Weigh 1 part of soybean protein powder, add 4 parts of 2% sodium hydroxide aqueous solution, stir and heat to 60° C., dissolve and defoam to obtain soybean protein alkali solution.

Abstract

The invention relates to a protein viscose fiber and a preparation method thereof, belonging to the textile field and aiming at solving a technical problem about how to provide a method for adopting different animal and plant proteins as materials to prepare the protein viscose fiber. The preparation method of the protein viscose fiber includes the following steps: 1. the animal and plant proteinsare 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 a protein spinning liquor; 4. the protein spinning liquor is blended with a glue to be spun to obtainprotein filaments; 5. the protein filaments are washed by peroxide solution and are oiled, dried and formed into cylinder form to get the protein viscose fiber. The protein viscose fiber preparation method of the invention does notadopt 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 andthe manufacturing can be realized with the existing viscose fiber preparation equipment.

Description

technical field [0001] The invention relates to 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. 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. [0003] Animal and vegetable protein raw materials are processed through degreasing, decolorization, deodorization and other processes to obtai...
