Pre-oxidized silk fire-retardant cotton is used as a back-facing fire-retardant layer for curtains, carpets, and decorative materials.

Pre-oxidized fiber fire-resistant cotton, professionally known as polyacrylonitrile pre-oxidized fiber nonwoven fabric, is a nonwoven material made from specialized polyacrylonitrile fibers that have undergone high-temperature thermal stabilization. Unlike conventional flame-retardant materials that rely on chemical additives for their performance, this product achieves its fire-resistant properties through a molecular “pre-oxidation” process and is spun into a felt-like material via needle-punching technology. It is suitable for applications in thermal insulation, high-temperature resistance, and fire protection.

Pre-oxidized silk fire-resistant cotton, with its unique properties of being non-combustible, highly temperature-resistant, and soft yet lightweight, plays a vital role in modern industrial and safety systems. Its applications span multiple critical sectors, deeply integrating into every stage—from manufacturing and production to everyday protective measures—and thus forming a comprehensive, multi-dimensional safety protection network.

In the field of industrial high-temperature equipment protection, pre-oxidized fiber fire-resistant cotton serves as the cornerstone for ensuring the safety and efficiency of core production facilities. It is used for thermal insulation and sealing in equipment such as high-temperature pipelines, kilns, boilers, and hot presses. As an efficient thermal insulation layer, it can significantly reduce heat loss, directly lowering energy consumption costs. At the same time, it forms a reliable physical barrier that prevents personnel from suffering burns. More importantly, its outstanding resistance to thermal shock and dimensional stability ensure that, even under harsh operating conditions characterized by frequent equipment starts and stops and extreme temperature fluctuations, it can continue to operate reliably over the long term without crumbling or losing effectiveness, thereby providing a solid guarantee for continuous production.

In the transportation sector—particularly in today’s pursuit of lightweight designs and high safety standards—the application of pre-oxidized fiber fire-retardant cotton is of paramount importance. In aerospace, high-speed rail, and the automotive industries, it is used as an insulating and fire-resistant layer in high-temperature areas such as engine compartments and exhaust systems. In recent years, with the rapid growth of new-energy vehicles, this material has become a critical component in the safety design of power battery packs. Laid between individual cells or above battery modules, it effectively slows down the rate at which thermal runaway from a single cell can spread to adjacent cells, thereby buying precious “golden time” for the battery management system to issue early warnings and for passengers to evacuate safely in an emergency. Moreover, it is also... Aircraft and high-speed rail seats, interior panels An important fire-resistant buffer padding that enhances the overall passive safety level of the passenger cabin. 。

In the fields of architecture and public safety, pre-oxidized silk fire-resistant cotton serves as a core material in the “passive fire protection” system, discreetly integrated into various critical nodes of building structures. It is used to seal cable shafts and ventilation ducts where they pass through floor slabs and walls in high-rise buildings, effectively and tightly preventing the vertical spread of flames and toxic smoke. At the same time, it also makes an ideal filling material for fire doors and fire-rated partition walls, providing a stable thermal barrier that resists fire. In public venues with high occupancy—such as theaters, hotels, and shopping malls—it is frequently... Fire-retardant backing layer for backdrops, carpets, and decorative materials By addressing fire hazards at the detail level, we can enhance the overall fire safety of buildings—and even seamlessly integrate these solutions behind kitchen appliances or around fireplaces in high-end residences, safeguarding family safety.

In the fields of fire emergency response and specialized personal protective equipment, pre-oxidized silk fire-resistant cotton is stepping from behind the scenes into the spotlight, directly safeguarding human life and safety. Thanks to its outstanding properties—non-combustible, non-melting, low-smoke, and non-toxic—it is used to manufacture... Fire escape blankets, thermal linings for firefighters’ fire-resistant protective suits, and inner linings for fire helmets. is the ideal choice. At critical rescue scenes, this material provides life-saving support of utmost importance to those heading against the flow and those trapped. At the same time, it also... Applied in professional equipment such as special welding blankets, high-temperature smelting protective suits, and arc-flash-resistant gloves. It builds a reliable line of defense for workers in industries such as petrochemicals, power generation, and metal processing.

In addition, its functionality also extends to: Specialized Filtration and Acoustic Management and other related fields. In the chemical and metallurgical industries, it can be used for filtering medium- and high-temperature flue gases below 250℃ and is resistant to certain chemical corrosions. Its fluffy, porous fiber structure effectively absorbs sound wave energy; therefore, it is often incorporated into cabin walls and floors of automobiles and ships as an acoustic insulation and noise-reduction material, enhancing safety while improving comfort.

The pre-oxidized fiber fire-resistant cotton produced and sold by Kaidun Industrial comes in a variety of specifications and sizes, supporting flexible customization of basis weights from 80 to 2000 g/m², widths from 1 to 2.4 m, and thicknesses from 1 to 15 mm, thereby meeting diverse customer needs.
