How can Pure Polyester Low Melting Yarn 110 Degree maintain its stable melting point characteristics during the manufacturing process?

In the process of manufacturing Pure Polyester Low Melting Yarn 110 Degree, it is crucial to ensure its stable melting point characteristics. First of all, ensure the quality of the raw materials from the source. Select high-quality polyester chips as raw materials. These chips should have good thermal stability, uniform molecular weight distribution and low ash content. At the same time, the environmental protection of the raw materials should be taken into account, and raw materials containing harmful substances should be avoided. The raw materials need to be pretreated before they are put into production, including drying, impurity removal and other steps. Drying can remove moisture from the raw materials to prevent bubbles or breaks during the spinning process; impurity removal is to ensure the purity of the raw materials and avoid the influence of impurities on the performance of the yarn.
The temperature control of the spinning machine is the key, which directly affects the melting point and structure of polyester fibers. Through precise temperature sensors and control systems, the temperature of the melt is ensured to be stable during the spinning process, so as to obtain fibers with consistent melting points. The fibers after spinning need to go through a stretching and cooling process to further fix their structure. The stretch multiple and cooling rate need to be precisely adjusted according to the characteristics of the fiber and the target melting point to achieve the ideal fiber performance.
During the drafting process, the fiber reaches the predetermined fineness and strength by precisely controlling the drafting multiple and speed. At the same time, the uniformity of the drafting process should be ensured to avoid uneven thickness. Forming is a key step in stabilizing fiber performance. By setting the appropriate temperature and tension, the fiber can achieve a stable structure and performance during the shaping process. The fiber after shaping should have a consistent melting point, good dimensional stability and heat resistance.
Set up online monitoring equipment on the production line, such as laser melting point tester, strength tester, etc., to monitor key indicators such as the melting point and strength of the yarn in real time. Once an abnormality is found, adjust the production parameters immediately to ensure product quality. Carry out strict inspection of the finished product, including appearance inspection, performance testing, etc. Ensure that each batch of products meets the established quality standards and customer requirements.
Keep the production workshop clean and dry to reduce the interference of dust and moisture. At the same time, control the temperature and humidity of the workshop to ensure the stability of the production environment. Strengthen safety protection measures in the production process, such as fire prevention and explosion prevention, to ensure production safety.
Through efforts in raw material selection and pretreatment, spinning process control, drafting and shaping, quality control and testing, environmental control, process optimization and continuous improvement, it can ensure that pure polyester low-melting point yarn 110 degrees maintains its stable melting point characteristics during the manufacturing process, providing reliable guarantee for subsequent applications.
