Innovative Breakthrough In Flame-Retardant Fibers And Market For Flame-Retardant Textiles

Statistics from relevant departments show that the annual fire disasters in China will cause economic losses of more than 500 million yuan to the society.

The serious fires caused by flammable products account for more than half of the total number of fires.

Therefore, the use of flame-retardant properties

It is very necessary and important.

Flame retardant will also become an essential attribute and development trend of future textiles.

In May 29th, a discussion on the development technology and direction of flame retardant fiber was launched in Beijing.

Innovative breakthrough in flame retardant fiber

Although the research on flame retardant fibers in China has already started since early, the real achievement of new development is in the 90s of last century, which basically meets the protection needs of some special fields.

However, with the improvement of people's living standards, people's requirements for flame-retardant textiles have evolved from simple protection to the pursuit of comfortable, breathable and better dyeing properties. Permanent, safe, non-toxic and green production become the basic requirements of the new generation of flame retardant textiles.

Beijing Sai LAN flame retardant fiber Co., Ltd. R & D team after more than ten years of painstaking research, mastered the environmentally-friendly silicon nitride flame retardant and silicon nitride flame retardant fiber preparation technology core technology, successfully developed flame retardant regenerated cellulose fibers.

Bi Shenping, general manager of Sao LAN, said that the product is now the world's first, and to some extent, it has made up for the defects of poor spinnability, large volume of smoke and environmental protection of the existing flame retardant regenerated cellulose fibers, which overcomes the shortcomings of poor comfort, moisture absorption and sweat tolerance of the finished products.

It is understood that the fire retardant regenerated cellulose fiber has been applied in many downstream enterprises, and has achieved good results.

Xu Yuanbin, general manager of Shandong Silver Eagle Chemical Fiber Co., Ltd., said that the company has worked with saelan for two years, and after many tests, it has successfully produced batch products with a pass rate of more than 95%.

At present, the production line's technology, technology, personnel and supporting facilities are all mature, and we plan to advance to the large production line in the second half year.

Zhao Aiguo, assistant director of cheerful Home Textile Co., Ltd., revealed that the company has developed flame retardant home textile fabrics using flame retardant regenerated cellulose fibers, and experiments show that the product has good flame retardancy.

Speaking of the promotion of flame retardant regenerated cellulose fiber, Bi Shenping proposed to set up a flame retardant textile industry alliance including fiber, yarn, fabrics, printing and dyeing, finished products enterprises and academic research institutions, and share the results of the alliance with the form of virtual shares.

At present, Sao LAN has signed a cooperation agreement with 4 downstream enterprises, such as cheerful home textiles, to jointly develop the flame retardant textile market.

Flame-retardant textiles market needs to be developed

Western developed countries attach great importance to flame-retardant textiles and pay close attention to them.

Zhao Aiguo introduced that in developed countries and regions, especially the United States, the requirements for flame-retardant and fire-retardant properties of textiles exported to the United States are particularly strict, and different technical specifications are specially made by the consumer product testing and certification scheme for the flame retardancy of various textile products. Currently, over 70% of the houses are permanently flame-retardant fabrics.

At present, China has issued relevant regulations on flame-retardant protective clothing, civil buildings and household interior decoration fabrics, but the domestic flame retardant textile market is still developing slowly.

Despite the increasing demand for flame retardant textiles in recent years, the proportion of genuine use of environmentally friendly flame retardant products, especially the permanent flame retardant products, is still very low. In some special places, the flame retardant finishing agent is only used to achieve the flame retardant effect.

He Yanli, vice president of China Chemical Fiber Industry Association, analyzed that despite the promotion of the national industrial policy, people's awareness of flame-retardant and fire prevention is relatively weak, and the concept of fire protection is also conservative. The flame retardant textiles are mainly used in the field of military and personal protection.

She suggested that in the future, we should strengthen the formulation of national standards for flame retardant fibers, increase the implementation of mandatory standards, and penetrate the flame retardant products into the field of people's livelihood and enter the homes of ordinary people.

Jiang Shicheng, academician of the Chinese Academy of engineering, also believes that the lag of standard will affect the development of flame retardant fibers, and the construction of future flame retardant fiber regulations needs to be strengthened, and the mandatory regulations need to be more sound.

Multifunctional environmental protection is the direction of development

In recent years, the EU REACH regulations are more stringent on the use of flame retardants. Yu Jianyong, a member of the Chinese Academy of engineering, believes that for enterprises, this is both a challenge and an opportunity for the development of new flame retardant fibers.

Laws and regulations strictly require high efficiency, halogen free, low smoke and low toxicity of flame retardants, and have little effect on other properties of materials. The application of environment-friendly flame retardants will also greatly promote the innovation of flame-retardant textiles.

Yu Jianyong believes that in the future, general flame retardant fibers should be developed in various directions to meet multiple needs.

For example, from the aspects of high performance, high quality, multifunctional fiber, flexible production, green processing and so on, we will develop dual function and multifunctional flame retardant fibers, such as flame retardant, antistatic, flame retardant, easy to stain, flame retardant and antibacterial. Develop flame retardant masterbatch, polyester melt modification technology and melt on-line modification technology to provide technical support for low cost and high efficiency production, so that the process is non-toxic, non polluting, energy saving and emission reduction.

At the same time, we should speed up the industrialization of special flame retardant fibers, pay attention to the development of application and market application of flame-retardant fiber products.

He also stressed that there are several important tasks to be done in the future, such as in-depth study of the combustion properties and combustion theory of fibers, testing methods for strengthening the combustion properties of fiber textiles, and formulating and improving the flame retardant regulations and standards for fiber textiles.

Yao Mu, academician of the Chinese Academy of engineering, also proposed that the flame retardant fibers should be developed towards a composite and multi-functional direction in the future. We should persist in innovation in preparation and methods, and take the road of green and environmental protection.

Professor Shi Meiwu, a professor at the general Quartermaster Equipment Research Institute, put forward his own views on the application of flame-retardant cellulose fibers in the armed forces, armed police, peacekeeping forces and civilian areas.

He believes that flame retardant fabric should not only solve the problem of flame retardant, but also consider the requirements of appearance, comfort and strength.
