Flame retardant fabric details
Flame retardant fabric details
At present, the main flame-retardant fabrics include: finishing flame-retardant fabrics, such as pure cotton, polyester cotton, etc.; intrinsic flame-retardant fabrics, such as aramid, acrylic cotton, DuPont Kevlar, Nomex, Australian PR97, etc.
Ellen Wuagneux, deputy editor-in-chief of the American “Nonwoven Industry”, made a brief analysis of flame retardant technology. He believes that the flame retardant material marketing industry is booming, but raw material suppliers are not synchronized; new regulations at the state and federal levels in the United States and the rise of modern technology have unprecedentedly posed new requirements and challenges to this industry. Edonis mentioned that the company has developed better flame retardants by integrating PROBAN and PYROVATEX flame retardant technologies, which have better performance in terms of flame retardant performance, environmental protection, color, and feel.
Disposable flame retardant fabric
Disposable flame-retardant fabrics are the prototype of flame-retardant products. Due to their low technical difficulty and low cost, they once became the main product in the flame-retardant fabric market. However, they are not resistant to water washing and flame retardants are harmful to the environment and human body, which limits the promotion of disposable flame retardant products. At present, such products are mainly used in decorative fields such as fabric sofas. With the gradual and steady popularity of durable pure cotton flame retardant and modified polyester permanent flame retardant fabrics, disposable flame retardant products will gradually be replaced.
Pure cotton durable flame retardant fabric
Cotton products have always been a popular trend in the fabric market, and their wearing comfort has always been highly sought after by people. After finishing the pure cotton fabric, this product can effectively prevent the spread of flames and protect the original excellent properties of the fabric. Pure cotton durable flame-retardant fabric has good washing resistance, non-toxic and odorless, safe and reliable for the human body, breathable and moisture-permeable, soft to the touch, and comfortable to wear. In terms of active combustion, the anti-melting performance is outstanding. At present, pure cotton flame-retardant fabrics fully meet the flame-retardant indicators: damage length ≤ 120mm, afterburning time ≤ 2 seconds and smoldering time ≤ 2 seconds. The main products include pure cotton woven fabrics (such as khaki, gauze, double-sided flannel, plain cloth, etc.), canvas, etc. It is suitable for making flame retardant protective clothing in metallurgy, machinery, forestry, fire protection and other industries.
Modified polyester permanent flame retardant fabric
Modified polyester permanently flame-retardant fabric is made of flame-retardant modified polyester staple fiber. In addition to its permanent flame retardant properties, the fabric also has high strength and elastic recovery capabilities, as well as good acid and alkali resistance. It is widely used in making labor protection clothing and industrial decoration products. However, due to the poor hygroscopicity of modified polyester permanent flame-retardant fabrics, polyester fabrics feel stuffy when worn, are easily charged with static electricity, are contaminated with dust, and melt droplets occur when burned, which greatly restricts their development prospects.
NOMEX permanently flame retardant fabric
In view of the fatal shortcoming of modified polyester permanent flame retardant fabrics causing secondary damage when burning, a new generation of permanent flame retardant fabrics emerged – NOMEX permanent flame retardant fabrics. This product was developed by DuPont. It has the outstanding advantages of modified polyester permanently flame-retardant fabrics. At the same time, it does not cause melt droplets when burning, has good anti-static properties, and has higher strength, making NOMEX permanently flame-retardant fabrics a natural choice for special combat clothing. The perfect choice for fire safety clothing. At the same time, with the development of society, NOMEX permanent flame retardant fabrics will gradually become the protagonist of protective products.
Aramid 1313 permanent flame retardant fabric
Aramid 1313 permanent flame retardant fabric is a mature permanent flame retardant material developed in China. Its performance is basically the same as NOMEX. It has gradually replaced similar imported materials. Because of its good price competitiveness, it has been widely used in China. , export prospects are promising.
