Flame-retardant sewing thread and production process thereof

Abstract

The invention discloses a flame-retardant sewing thread and a production process thereof. The flame-retardant sewing thread comprises a flame-retardant sewing thread base layer and a flame-retardant sewing thread outer layer, wherein the flame-retardant sewing thread base layer and the flame-retardant sewing thread outer layer are formed through processing by flame-retardant sewing thread production equipment, the flame-retardant sewing thread base layer adopts aramid fiber1313, the flame-retardant sewing thread outer layer is divided into two strands, the flame-retardant sewing thread base layer is disposed between the two strands of the flame-retardant sewing thread outer layer, and the flame-retardant sewing thread base layer and the two strands of the flame-retardant sewing thread outer layer are interwoven into the flame-retardant sewing thread. The flame-retardant sewing thread not only has a flame retardant effect, but also has skin friendliness, good hand feeling and good sweatabsorption and gas permeability through the arrangement of cotton yarns and flax yarns in the flame-retardant sewing thread outer layer, is suitable for being worn by the human body, does not easilycause skin diseases, has few fluffs, higher strength and softer and more comfortable hand feeling, and has a simple entire production process and low cost.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to a flame-retardant sewing thread and a production process thereof. Background technique [0002] Flame-retardant sewing thread has a low ignition point, good flame-retardant effect, is not easy to ignite, and is self-extinguishing from the fire, and has waterproof function to achieve permanent flame-retardant effect. Flame-retardant sewing thread is widely used in fire-fighting, electric welding, and sewing of fire-resistant and high-temperature resistant textiles. With the development of society, flame-retardant sewing thread has also entered the lives of ordinary people and is made into leather products, clothing, handbags , shoe uppers, wallets, travel bags, leather gloves, tents, chair covers, suitcases, leather goods, etc. From the application of the above flame-retardant sewing thread, it can be seen that the flame-retardant sewing thread is widely used and is in...

AI Technical Summary

Problems solved by technology

From the application of the above flame-retardant sewing thread, it can be seen that the flame-retardant sewing thread is widely used and is in close contact with people's skin, but the existing flame-retardant sewing thread is mainly divided into pure polyester flame-retardant thread and aramid flame-retardant sewing thread , or there are flame-retardant adhesives on both sides of the base layer. Pure polyester flame-retardant threads and aramid flame-retardant sewing threads are not conducive to long-term contact with human skin, and the air permeability is poor. At the same time, both sides of the base layer are limited by flame-retardant adhesives. When wearing, the flame-retardant rubber will directly contact with the human body. Most of the flame-retardant rubber has a hard texture, and human skin is not suitable for such fabrics. Moreover, the flame-retardant rubber does not absorb sweat and is not breathable, which is easy to cause skin diseases and seriously affects the user's health. Experience, so there is an urgent need to develop a flame-retardant sewing thread worn by the human body
