What is the effect of twisting process on the quality of twisted nylon yarn

The twisting process is an important part of the twisting treatment of yarn in the textile industry, and has a significant impact on the quality of twisted nylon yarn. In the twisting process, the selection of twisting machines, twisting speed, twisting tension, twisting direction and other parameters are crucial. Through a scientific and reasonable twisting process, the strength, softness, wear resistance and stability of the yarn can be effectively improved.

In the twisting process, the selection of twisting machines is one of the key factors that determine the quality of twisted nylon yarn. Different types of twisting machines have their own unique structures and twisting principles, such as ring twisting machines, friction twisting machines, airflow twisting machines, etc. Reasonable selection of twisting machines can customize the twisting treatment according to the needs of the yarn to ensure the twisting effect and quality stability of the yarn.

Twisting speed is one of the important parameters that affect the quality of twisted nylon yarn. Twisting speed refers to the speed at which the yarn rotates on the twisting machine, usually measured in revolutions or meters per minute. Appropriate twisting speed helps the yarn fibers to be tightly bonded, improving the strength and wear resistance of the yarn; while too high or too low twisting speed will affect the twisting effect and quality of the yarn.

Twisting tension is also one of the key factors affecting the quality of twisted nylon yarn. Twisting tension refers to the tension applied to the yarn on the twisting machine, usually expressed as a tension value. Appropriate twisting tension helps the yarn fibers to be tightly bonded, improving the strength and stability of the yarn; while too high or too low twisting tension will cause the yarn to break or deform, affecting the quality and appearance of the yarn.

Twisting direction also has an important influence on the quality of twisted nylon yarn. Twisting direction is divided into S-direction twisting and Z-direction twisting. Choosing a suitable twisting direction helps make the yarn more uniform and stable, reduce the twisting and deformation of the yarn, and improve the quality and appearance of the textile.

In addition, in the twisting process, the precise control of parameters such as twisting degree, twisting uniformity, and twisting density also has an important influence on the quality of twisted nylon yarn. Scientific and reasonable adjustment of these parameters can adjust the structure and performance of the yarn, improve the strength, softness and stability of the yarn, and meet the needs of different textile production.
