Embodiment 1

[0047] A kind of production method of the special-shaped fiber containing amino acid, it is carried out according to the following steps successively:

[0048] (1) Prepare raw materials: crush the cottonseed meal after cottonseed hulling into ≤1mm material, put it into the reaction kettle, add NaOH solution with a concentration of 15% according to 10 times the weight of the material, adjust the pH to 12.5, soak After 2 hours, be heated to 75° C., control the reaction time under stirring conditions to be 60 minutes, then filter the discarded residue, collect the filtrate, and adjust the pH of the filtrate to be 4.5 with HCl with a concentration of 15%, so that the protein in the filtrate is precipitated. analysis, and then filtered to obtain the protein as a raw material for later use.

[0049] (2) Modification and activation: put the protein material prepared in the raw material step into the reaction kettle, add clear water to make a protein solution with a concentration of 1...

Embodiment 2

[0062] A kind of production method of the special-shaped fiber containing amino acid, it is carried out according to the following steps successively:

[0063] (1) Preparation of raw materials: commercially available protein powder products are used directly as raw materials for backup.

[0064] (2) Modification and activation: Put the finished protein powder raw materials into the reaction kettle, add clear water to make a protein solution with a concentration of 8%, and adjust the pH of the protein solution to 13 with NaOH, anchor stirring to fully dissolve the protein, and then press The ratio of 10mg / kg protein raw material weight to add modifier: LiClO 4 , control the reaction temperature to 95°C, carry out the protein modification reaction under the condition that the anchor stirring speed is 60 rev / min, the reaction time is 70 minutes, and when the temperature is lowered to 80°C, the protein modification reaction is carried out according to 0.3% of the weight of the pro...

Embodiment 3

[0074] A kind of production method of the special-shaped fiber containing amino acid, it is carried out according to the following steps successively:

[0075] (1) Preparation of raw materials: commercially available protein powder products are used directly as raw materials for backup.

[0076] (2) Modification and activation: put the finished protein powder raw materials into the reaction kettle, add clear water to make a protein solution with a concentration of 12%, and adjust the pH of the protein solution to 12 with NaOH, stir to fully dissolve the protein, and then press 20mg / Add modifier: KCl according to the weight of kg protein raw material, control the reaction temperature to 110°C, carry out the protein modification reaction for 55 minutes under the working condition of the anchor stirring speed of 70 rpm, and wait until the temperature is lowered to 90°C, then Add the key-opening agent: peracetic acid according to 0.7% of the weight of the protein raw material, an...

Abstract

The invention discloses a production method of a profile fiber that contains amino acid, is implemented according to the steps of raw material preparation, modification and activation, stock solution preparation, wet spinning and shaping processing, etc., and is characterized in that protein is firstly transformed into the amino acid with uncovering reactive groups, the amino acid is grafted, copolymerized and blended with a molecular chain of a raw material of a synthesized fiber and led into a stock spinning solution, the spun fiber silk is processed by shaping, and the amino acid that is blended with the molecular chain of the synthesized fiber through hydrogen bond force drops randomly, thus forming an irregular cross section shape with irregular grooves and transverse heteromorphic orifices in the fiber lengthwise direction. The profile fiber that contains the amino acid is a novel fiber material with superior quality and excellent performance, and approximates the unique quality of moisture absorption and wicking, skin nearness and comfort, air permeability and heat preservation of natural silk floss fibers. The production method of the profile fiber that contains the amino acid has remarkable advantages of simple and fast techniques, rich raw material source and low production cost, as well as great social and economic benefits and enormous market prospect.

Description

Technical field: [0001] The invention relates to a production method of a new type of fiber, which belongs to the technical field of "artificial silk or the like of other raw materials, and its production method" contained in the International Patent Classification, specifically a production of a special-shaped fiber containing amino acids method. Background technique: [0002] The fiber raw materials used in the traditional textile industry during the dry period are roughly divided into two categories: one is pure natural animal protein fibers such as silk, wool, cashmere, and the other is plant cellulose fibers such as cotton and hemp. Generally speaking, these two types of natural fibers have unique and irregular cross-sectional shapes, which are determined by the nature of the natural fibers themselves. The important characteristic of "irregular cross-sectional shape" of natural fibers is the main reason for the specific quality and excellent performance of natural fibe...
