In the production process of polyester yarn, how to control the key parameters such as yarn density and twist to ensure quality?

In the production process of polyester yarn, controlling the key parameters such as yarn density and twist is an important link to ensure product quality. Here are some main measures:
Control yarn density
Raw material selection and pretreatment: Select polyester chips or filaments that meet the requirements as raw materials to ensure their specifications and stable quality. Through pretreatment processes such as drying and impurity removal, reduce the moisture and impurities in the raw materials to provide good conditions for the spinning process.
Spinning process control: In the spinning process, strictly control the spinning temperature, pressure, speed and other process parameters to ensure uniform yarn fineness. By adjusting the aperture and number of holes of the spinneret, as well as the stretching multiple, the yarn density can be accurately controlled.
Online monitoring and feedback: Use modern sensing technology and computer control systems to monitor and feedback the spinning process in real time. Once a linear density deviation is found, adjust the process parameters immediately to ensure stable product quality.
Controlling yarn twist
Twisting process optimization: During the twisting process, select the appropriate twisting machine according to product requirements, and optimize the twisting process parameters, such as twist, twist direction, tension, etc. By adjusting the spindle speed, roller spacing, twisting angle, etc., ensure that the yarn twist is uniform and meets the standard.
Quality inspection and adjustment: During the production process, samples are regularly taken for twist testing. Use instruments such as twist testers to accurately measure the twist value of the yarn and compare it with the standard value. If deviations are found, adjust the twisting process parameters in time to ensure stable product quality.
Employee training and awareness improvement: Strengthen the training and awareness improvement of production employees to make them understand the importance of yarn twist control and operating specifications. Through regular assessment and reward and punishment mechanisms, employees are encouraged to actively participate in quality control activities and improve the overall production level.
Through measures such as raw material selection and pretreatment, spinning process control, online monitoring and feedback, and twisting process optimization, key parameters such as linear density and twist of polyester yarn can be effectively controlled to ensure stable and reliable product quality.

Why are cotton socks suitable for summer?

The reason why cotton socks are suitable for summer is mainly due to their unique physical properties and optimization of the foot environment.
Cotton socks are known for their excellent moisture absorption. In the hot summer, the human body is prone to sweating, especially the feet, which are more likely to produce moisture and stuffiness due to being wrapped in shoes for a long time. Cotton socks can quickly absorb sweat discharged from the feet and disperse it on the surface of the socks, gradually evaporating through air circulation, thereby keeping the feet dry. This feature effectively reduces the possibility of sweat accumulation on the feet, reduces the environment for bacterial growth, and helps prevent foot odor and infection.
Cotton socks have good breathability. The natural structure of cotton fibers allows smooth air circulation, and even in a closed shoe environment, a certain amount of air exchange can be maintained. This breathability helps to reduce foot temperature, reduce stuffiness, and make wearing more comfortable.
Cotton socks are also loved by people for their skin-friendly and comfortable characteristics. Pure cotton material is soft and delicate, friendly to the skin of the feet, and reduces the discomfort caused by friction. This comfort is especially important in the summer, as it can reduce foot fatigue and improve the overall wearing experience.
Cotton socks are an ideal choice for summer wear due to their excellent moisture absorption, good breathability, and skin-friendly comfort. They can effectively keep feet dry, prevent odor and infection, and provide a comfortable wearing experience. Therefore, when buying summer socks, cotton socks are undoubtedly one of the recommended options.
