Problems solved by technology

At present, the most commonly used degreasing methods for fiber degreasing include soda ash degreasing and solvent degreasing agent. Due to the soda ash degreasing agent, the temperature cannot be too high, so the degreasing effect is not complete; although solvent degreasing has high degreasing efficiency, it is

Embodiment 1

[0032] The present invention is a kind of natural cashmere bio-enzyme degreasing method, comprises the following steps:

[0033] Step 1: Remove the flesh and dust attached to the cashmere, add the cashmere to clean water, and stir to fully infiltrate the cashmere. The temperature of the soaking water is maintained at 25°C, and the soaking time is 15 minutes. Then remove the soaked cashmere and spread it with clean water Rinse for 3 minutes;

[0034] Step 2: Soak the cashmere in a weak alkaline solution with a compound degreasing agent to degrease once. The pH of the weak alkaline solution is 8, the soaking temperature is 60°C, and the soaking time is 30 minutes;

[0035] Step 3: Rinse the cashmere once with hot water, first with hot water at 60°C for 5-10 minutes, then with hot water at 45°C for 15 minutes;

[0036] Step 4: Soak the cashmere with biological enzymes in a weakly acidic solution for secondary degreasing, the pH of the weakly acidic solution is 4, the soaking tem...

Abstract

The invention discloses a natural cashmere degreasing method adopting a biological enzyme process. The natural cashmere degreasing method comprises the following steps: 1, removing the flesh and dustattached to cashmere and adding the cashmere in clean water for soaking; 2, using a composite degreasing agent to soak the cashmere in a weak alkaline solution so as to execute primary degreasing; 3,flushing the cashmere once with hot water; 4, soaking the cashmere with a biological enzyme in a weakly acidic solution so as to execute secondary degreasing; 5, using hot water to conduct secondary flushing on the cashmere and executing drying to obtain degreased cashmere. The natural cashmere degreasing method adopting the biological enzyme process integrates degreasing with the inorganic composite degreasing agent and degreasing with the biological enzyme, the degreasing with the inorganic composite degreasing agent is executed under a higher-temperature alkaline condition, and effective degreasing can be achieved; by means of degreasing with the biological enzyme, the cashmere can be more deeply decreased by cooperatively using candida lipase and papain, and the degreasing effect is more optimized and thorough.

Description

technical field [0001] The invention belongs to the technical field of fiber degreasing, and in particular relates to a biological enzymatic degreasing method for natural cashmere. Background technique [0002] The main component of animal hair fiber is a protein composed of a series of amino acids combined into a chain structure through peptide bonds, which is an excellent textile raw material. Because coarse animal hair fibers contain lipids, lipids form serious barriers to enzymes, reducing agents, swelling agents, etc.; subsequent processes of oil hydrolysis of cutin, such as decolorization, ultrafiltration, nanofiltration, etc., cause work efficiency to be blocked due to micropores Greatly reduce and seriously affect the quality of woolen fibers. Therefore, an important step in processing and utilizing animal hair fiber is to degrease first. At present, the most commonly used degreasing methods for fiber degreasing include soda ash degreasing and solvent degreasing ag...
