The manufacturing method of polyester cotton yarn 

Polyester cotton yarn is a chemical raw material made by mixing polyester and cotton fibers, widely used in textile, clothing and other fields. The manufacturing methods of polyester cotton yarn mainly include raw material preparation, blending, spinning, post-processing and other processes. This article will provide a detailed introduction to the manufacturing method of polyester cotton yarn

1、 Raw material preparation 

1 Polyester fiber preparation: Polyester fiber is a synthetic fiber made through polymerization reaction, which has advantages such as high strength, good elasticity, and wear resistance. Polyester fibers need to undergo drying, impurity removal, and other treatments before use to ensure their quality and spinnability

2. Cotton fiber preparation: Cotton fiber is a natural fiber with advantages such as good moisture absorption and strong breathability. Cotton fibers need to be cleaned and combed before use to remove impurities and improve fiber parallelism

2、 Blending is the process of mixing polyester fibers and cotton fibers together in a certain proportion. Blending can be achieved through mechanical mixing or airflow mixing to ensure uniform fiber mixing. In the blending process, it is necessary to adjust the ratio of polyester and cotton fibers according to the requirements of the product to achieve the desired performance and appearance

3、 Spinning is the process of processing mixed fibers into yarn. The spinning processes of polyester cotton yarn mainly include ring spinning, rotor spinning, and jet spinning. Among them, ring spinning is the most widely used spinning process, which works by twisting fibers through high-speed rotating spindles and wire coils to form yarn. During the spinning process, it is necessary to control parameters such as twist and tension of the yarn to ensure its quality and weaving ability

4、 Post treatment of polyester cotton yarn includes processes such as desizing, boiling, bleaching, and drying to improve the quality and wearability of the yarn. Desizing is to remove the pulp from the yarn, boiling is to remove impurities from natural fibers, bleaching is to improve the whiteness of the yarn, and drying is to remove moisture from the yarn. In the post-processing process, it is necessary to control the temperature, time and other parameters of each process to ensure the quality and quality of the yarn

In summary, the manufacturing method of polyester cotton yarn requires strict control of the process parameters and quality indicators of each process to ensure the quality and performance of the final product. At the same time, it is necessary to strengthen environmental management and energy consumption control in the production process, improve production efficiency and economic benefits

In the manufacturing process of polyester cotton yarn, the following points need to be noted: 

1 Selection of raw materials: The quality of polyester and cotton fibers has a significant impact on the quality of the final product, so it is necessary to choose high-quality and stable raw materials

2. Equipment maintenance and upkeep: The spinning equipment needs regular maintenance and upkeep to ensure the normal operation of the equipment and the stability of the product

3. Skill level of operators: The skill level of operators has a significant impact on the quality of products, so it is necessary to strengthen the training and management of operators, improve their skill level and sense of responsibility

In summary, the manufacturing method of polyester cotton yarn needs to comprehensively consider various factors such as raw materials, equipment, process, and operation, strengthen quality management and environmental protection management, in order to improve product quality and economic benefits.
