Polyester high-strength sewing thread refers to a thread twisted with continuous polyester high-strength and low-elongation filaments. It is resistant to high-temperature dyeing at 130 degrees. It is smooth and has no joints, good color fastness, high tensile strength, low elongation, and no elasticity. It is a sewing thread that meets the national environmental protection requirements.
Since the speed of sewing machines used in the modern clothing industry is as high as 5000 rpm or more, the quality requirements for sewing threads are even higher. Synthetic fiber polyester high-strength sewing thread has the characteristics of strong toughness, soft and smooth line quality, high breaking strength, good gloss, strong wear resistance, firm coloring, and no elasticity, which can meet the speed requirements of modern industrial sewing machines.
Polyester high-strength sewing thread has good properties such as high strength, good wear resistance, low shrinkage, good hygroscopicity and heat resistance, good chemical stability, corrosion and mildew resistance, and no joints. Polyester high-strength thread is widely used and can be used in clothing sewing of cotton fabrics, chemical fibers and blended fabrics.
Three Qualities That High-Strength Sewing Thread Must Have
- Smooth and smooth surface, uniform color, and sewing performance;
- Certain fastness and wear resistance;
- Small shrinkage rate.
What is the impact of the quality of polyester high-strength sewing thread
The quality of polyester sewing thread not only affects the sewing effect and processing cost, but also affects the appearance quality of the finished product. Therefore, polyester high-strength thread needs to select reliable polyester raw materials and be manufactured in strict accordance with process standards to ensure that its tensile strength and wear resistance and other performance requirements can meet industry standards.
Conclusion
Based on these characteristics of polyester high-strength sewing thread, the problems of thread breakage and thread change in actual use are reduced, and the sewn stitches can remain flat and beautiful without shrinkage, which is more conducive to improving productivity. It is suitable for sewing in the fields of footwear, professional clothing, leather furniture, leather accessories, etc.
