The manufacturing method
of human cotton cloth
1. Introduction

In the field of chemical production raw materials, the manufacture of human cotton cloth is an important technology. Human cotton cloth is widely used in clothing, household goods and other fields because of its comfort, ventilation and good moisture absorption. This article will introduce the manufacturing method of human cotton cloth in detail, including the selection of raw materials, preparation process, post-treatment and so on.

2. raw material selection

cotton cloth raw materials mainly choose high cellulose content of natural plant fibers, such as wood pulp, bamboo pulp and so on. These raw materials are chemically treated and mechanically processed to make man-made cellulose fibers, or rayon fibers. When selecting raw materials, factors such as cellulose content, fiber length and strength should be considered to ensure the quality and performance of human cotton cloth.

3. Preparation Process

1. Pulping
The selected raw materials are chemically treated to separate the cellulose and form a pulp. It is necessary to add appropriate chemicals in the pulping process to facilitate the separation and purification of cellulose.
2. Spinning
The prepared slurry is spun through a spinning machine to form rayon fibers. During the spinning process, it is necessary to control the fineness, length and strength of the fiber to ensure the quality of the human cotton cloth.
3. Weaving
The spun rayon fibers are woven through a loom to form rayon cloth. In the process of weaving, it is necessary to adjust the density, texture and color of the fabric according to the requirements.

4. post-treatment

1. Desizing
After the man-made cotton cloth is woven, it needs to be desizing treatment to remove the chemicals and impurities remaining on the fiber. During the desizing process, attention should be paid to control the temperature and pH to avoid damage to the fiber.
2. Bleaching
According to the need, the cotton cloth is bleached to improve its whiteness and color. The choice of bleaching agent should be determined according to the fiber type and bleaching requirements to ensure the bleaching effect and fiber quality.
3. Finishing
Finishing treatment of cotton cloth to improve its wrinkle resistance, elasticity and dimensional stability. In the finishing process, appropriate additives, such as softener, anti-wrinkle agent, etc., can be added to improve the feel and appearance of the cotton cloth.

5. quality control

In the manufacturing process of human cotton cloth, the quality of each link should be strictly controlled to ensure that the final product meets relevant standards and requirements. Specifically, we need to pay attention to the following aspects:

1. Raw material quality: Select high-quality raw materials to ensure the content and purity of cellulose to improve the performance and quality of human cotton cloth.
2. Preparation process: In the process of pulping, spinning and weaving, the process parameters should be controlled to ensure the quality of the fiber and the structure of the fabric.
3. Post-treatment: In the process of desizing, bleaching and finishing, the type and concentration of chemical agents should be controlled to avoid damage to fibers and fabrics.
4. Finished product testing: conduct a comprehensive quality testing of the finished products of human cotton, including the appearance quality, physical properties, chemical indicators and other aspects of testing to ensure that the products meet the relevant standards and customer requirements.

6. conclusion The manufacturing method of

man cotton cloth involves the control of multiple links and process parameters, and the quality of each link needs to be strictly controlled. Through reasonable raw material selection, preparation process and post-treatment, high-quality human cotton cloth can be produced to meet the needs of different fields. At the same time, strengthening quality control and finished product testing to ensure that the quality and performance of human cotton cloth meet relevant standards and requirements is of great significance for improving product competitiveness and market share.
