High Tenacity Polyester Filament   The raw material of sewing thread is high strength polyester filament, which has the characteristics of high strength, small elongation and high modulus. It adopts advanced flat drawing technology at home and abroad, uses paper tube to burn the filament, and the net weight of single spindle is about 6kg. It is convenient for transportation, avoids the shortcomings of iron tube recycling, and is convenient for use.

“High Tenacity Polyester Filament   Sewing thread is widely used in high-grade clothing, leather products, medical surgery, military products and other fields because of its high strength, good wear resistance, corrosion resistance and no joint. The polyester thread made of polyester filament with high strength and low shrinkage has good looping performance. The sewing thread is very stable in response to the changes of different forces, reducing thread breakage and thread change in the sewing thread, which is conducive to improving productivity. It is very suitable for sewing shoes, professional clothing, professional equipment, leather furniture and leather accessories. " Facing such a broad market prospect, Chen Jun, the leader of the project "spinning technology and industrialization of high strength and low elongation special composite sewing thread" and professor of Wuhan Textile University, is full of confidence in the project.

In the field of high-end sewing thread, the United States and the United Kingdom have occupied most of the market. Nowadays, the rapid development of China's chemical fiber textile industry will accelerate the development of the chemical fiber sewing thread industry, and greatly improve the international competitiveness of China's sewing thread. With the continuous emergence of various functional sewing thread, the sewing thread industry will continue to develop in the direction of high-grade and high value-added. China's sewing thread industry, especially the high tenacity polyester textile industry, will continue to develop   Sewing thread has a broad market prospect.  

What technical difficulties need to be overcome in the development of high strength and low elongation special composite sewing thread

One is to completely break through the shortcomings of low quality of traditional sewing thread, and creatively put forward to use high strength and low elongation chemical fiber filament and apply embedded spinning technology to produce high strength and low elongation special composite sewing thread (such as high tenacity polyester fabric)   The innovative idea of "sewing thread" improves the innovation of embedded spinning theory.

Second, we have developed and improved the required production equipment combined with the spinning system of spandex core spun yarn, and developed a complete set of embedded production equipment, which provides a guarantee for the realization of high-quality sewing thread products.

Third, in order to realize the above-mentioned embedded spinning principle, we have studied the spinning technology of high strength and low elongation special composite sewing thread, and developed and produced a series of high strength and low elongation special composite sewing thread products. The production process reduces three processes, greatly reduces the production cost, and realizes the efficient production of high strength and low elongation special composite sewing thread.

The progress of science and technology not only brings about the improvement of productivity, but also changes our life all the time   Sewing thread, as the representative of high-strength sewing thread, is also constantly improving our happiness and quality of life.
