The development trend of flame retardant textiles in my country

one. Strengthen the development and research of flame-retardant fibers

At present, post-finishing fabrics to obtain flame-retardant textiles with long-lasting flame retardancy, high performance, multi-function and other characteristics and their processing technology are the development direction and trend of flame-retardant fibers. However, at present, flame-retardant finishing fabrics are mostly produced and used in our country, including durable flame-retardant fabrics of pure cotton, pure polyester, pure wool, polyester-cotton and various blends, and non-durable wash-retardant fabrics of pure cotton, viscose, pure polyester. Flame-retardant fabrics, production and use of flame-retardant fiber fabrics
The quantity is very small, with an annual output of only about 100 tons. With the continuous improvement of people’s living and environmental conditions, people have higher and higher requirements for the performance of flame-retardant textiles, and efforts and funds should be invested to increase the development of flame-retardant fibers.

two. Strengthen research on multi-functionality of flame-retardant textiles

At present, most flame-retardant fibers or fabrics only have flame-retardant functions and cannot meet the special requirements of some departments, such as flame-retardant and water-repellent, flame-retardant and oil-repellent, flame-retardant and antistatic. It is imperative to develop flame-retardant multi-functional products. For example, various forms of production methods are combined to perform waterproof and oil-repellent finishing on flame-retardant fiber fabrics; flame-retardant fiber yarns are interwoven with conductive fibers to produce antistatic flame-retardant fibers; flame-retardant fibers and high-performance fibers are used Blended interweaving
Produce high-temperature-resistant fabrics; use flame-retardant fibers blended with fibers such as cotton, viscose, etc. to improve the comfort of the final product and reduce costs.

three. Develop new low-toxic, low-smoke, non-polluting flame retardants

The flame retardants selected for the production of flame-retardant polypropylene fibers are to switch from bromine-based to phosphorus-nitrogen system flame retardants and intumescent flame retardants, taking advantage of their good compatibility with polymers, low dosage, and high thermal stability. , produces low-smoke, low-toxic, non-corrosive and non-drip flame-retardant polypropylene fibers. The flame retardant used in the production of flame-retardant acrylic fiber will shift from halogen-based to phosphorus-nitrogen system flame retardant. In addition to flame-retardant properties, the fiber also has antistatic function. This kind of fiber has “double anti-static” function.
The high-performance acrylic fiber has low smoke, low toxicity, and good post-processing performance and usability. The development direction of flame-retardant polyamide is to seek new flame-retardant varieties that are durable, highly efficient, anti-drip, low in toxicity, low in smoke, and have little impact on various physical performance indicators. It will shift from the current bromine series to the phosphorus series and then to the nitrogen series. . The production of flame-retardant polyester is developing in the direction of fiber series with high added value. The flame retardant selected will shift from bromine-based to phosphorus-based compounds and other compounds will be added.
Functions, such as antistatic, low pilling, antibacterial and easy to dye, etc.

Four. Formulate regulations and standards and increase publicity

The improvement of laws and regulations has important practical value in promoting the development, promotion and application of flame-retardant textiles and in preventing fire accidents caused by flammable textiles. To correctly evaluate the flame retardant performance of textiles, the requirements of the use occasion should prevail, and standards should be formulated according to the use. The formulation of test methods should be based on actual fire conditions instead of small laboratory experiments. This is the development direction of textile flame retardant standards.

five. Strengthen exchanges and cooperation.

The research, development, production and application of flame-retardant textiles should be regarded as a system engineering, involving a wide range of industries. In addition to textile systems, other industrial fields should cooperate and support it. Therefore, exchanges and cooperation should be strengthened. At present, the China Textile Research Institute has established the “National Textile Flame Retardant Technology Collaboration Network”, which has attracted more than 60 member units, organizing scientific research, production, operation, information and other units together to timely exchange domestic and foreign textile flame retardant information. regulations, standards
Test methods, research results, regularly organize academic exchanges and edit and publish “Network News” about network members’ activities, and reflect opinions and suggestions on the development and application of flame-retardant textiles to the government department. International exchanges and cooperation will promote us to learn and draw on foreign advanced technology and experience, and shorten the gap between our country and developed countries.
