What is the difference between flame retardant sewing thread and other sewing threads? Compare with quartz fiber sewing thread.



Commonly used sewing thread models are 202, 203, 402, 403, 602, 603 and so on.



The thread is usually formed by twisting several strands of yarn side by side. The 20, 40, 60, etc. in front of the sewing thread model all refer to the count of the yarn. The count of the yarn can be simply understood as the thickness of the yarn. The finer; the 2 and 3 behind the model number mean that the sewing thread is made of several strands of yarn. For example: 603 is made of 3 strands of 60 yarns twisted together. Therefore, the sewing thread synthesized by twisting yarns with the same number of strands, the higher the count, the thinner the thread and the lower the strength; while the sewing thread twisted by the same number of yarns, the more strands, the thicker the thread and the stronger the strength. big.



Fire-resistant wire (also known as flame-retardant wire) has low ignition point, good flame-retardant effect, not easy to ignite, and self-extinguishing from fire, and has waterproof function to achieve a longer flame-retardant effect. You will see a clear difference.



The high temperature resistant quartz fiber sewing thread has a smooth and soft surface and good folding resistance, and has better high temperature resistance, weather resistance, mechanical strength and chemical resistance than the existing high silica sewing thread, carbon fiber sewing thread and glass fiber sewing thread.



Summary: Sewing thread and polyester thread are all fibers made of polyester in terms of raw materials. Polyester yarn is a polyester yarn used in conventional textiles. Sewing thread is a special polyester yarn, which is different from conventional polyester yarn in strength, shrinkage rate and elongation at break. Generally higher strength, less elongation, and lower boiling water shrinkage.
