H. T. Hollow Sewing Thread is currently in a good market and has great development prospects. There are few domestic companies specializing in the production of H. T. Hollow Sewing Thread.

　　The commonly used models of H. T. Hollow Sewing Thread 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 HT Hollow Sewing Thread model all refer to the yarn count. The yarn count can be simply understood as the thickness of the yarn. The higher the count, The finer the yarn; the 2 and 3 behind the model respectively indicate that the sewing thread is formed by twisting several strands of yarn. For example: 603 is made of 3 strands of 60 yarns and twisted together. Therefore, the higher the count, the thinner the thread and the lower the strength of the sewing thread made by twisting the same number of yarns; while the HT Hollow Sewing Thread made of the same number of yarns twisted, the more the number of strands, the thicker the thread. The greater the intensity.

Fire-retardant wire (also known as flame-retardant wire), low fire point, good flame-retardant effect, not easy to ignite, away from the fire and extinction, and has a waterproof function to achieve a permanent flame-retardant effect. It will be seen when compared with non-flame-retardant wires. To the obvious difference.

　　High temperature resistant quartz fiber sewing thread has a smooth and soft surface and good folding resistance. Compared with the existing high silica sewing thread, carbon fiber sewing thread and glass fiber sewing thread, it has more excellent high temperature resistance, weather resistance, mechanical strength and chemical resistance.
