Spunlace nonwoven of pre-oxygenated fiber
Product Introduction:
Pre-oxidized filament nonwoven fabric is a functional material made from pre-oxidized filament (polyacrylonitrile pre-oxidized fiber) through nonwoven processes such as needling and spunlace. Its core advantage lies in its inherent flame retardancy. It does not require additional flame retardants. When exposed to fire, it does not burn, melt or drip. It only carbonizes slightly and does not release toxic gases when burning, demonstrating outstanding safety.
Meanwhile, it has excellent high-temperature resistance and can be used in an environment of 200-220℃ for a long time, and can withstand temperatures above 400℃ for a short period, still maintaining mechanical strength at high temperatures. Compared with traditional rigid flame-retardant materials, it is softer, easier to cut and process, and can also be combined with other materials.
Its application focuses on the field of fire protection, such as the inner layer of fire suits, fireproof curtains, flame-retardant wrapping layers of cables, flame-retardant linings for automotive interiors, and battery electrode separators, etc. It is a key material for high-safety demand scenarios.
YDL Nonwovens can produce pre-oxygenated filament non-woven fabrics ranging from 60 to 800 grams, and the thickness of the door width can be customized.
The following is an introduction to the characteristics and application fields of pre-oxygenated wires:
I. Core Features
Intrinsic flame retardancy, safe and harmless: No additional flame retardants are needed. It does not burn, melt or drip when exposed to fire, but only undergoes slight carbonization. During the combustion process, no toxic gases or harmful smoke are released, which can effectively prevent the spread of flames and meet high safety standards.
High-temperature resistant and good shape retention: It can be stably used in an environment of 200-220℃ for a long time and can withstand temperatures above 400℃ for a short period. It is not prone to deformation or fracture in high-temperature environments and can still maintain a certain mechanical strength, meeting the requirements of high-temperature scenarios.
Soft texture and excellent processability: Relying on the spunlace process, the finished product is fluffy, soft and has a fine hand feel. Compared with needle-punched pre-oxygenated filament non-woven fabric or traditional rigid flame-retardant materials (such as glass fiber cloth), it is easier to cut and sew, and can also be combined with other materials such as cotton and polyester to expand application forms.
Stable basic performance: It has certain aging resistance and acid and alkali resistance. In daily storage or conventional industrial environments, it is not prone to failure due to environmental factors and has a long service life.
II. Main Application Fields
In the field of personal protection: As the inner layer or lining fabric of fire suits, fire-resistant aprons, and heat-resistant gloves, it not only plays a role in flame retardancy and heat insulation but also enhances the wearing comfort through its soft texture. It can also be made into an emergency escape blanket, which is used to quickly wrap the human body or cover flammable materials at the fire scene, reducing the risk of burns.
In the field of building and home safety: It is used for fireproof curtains, fireproof door linings, and flame-retardant ceiling veneers, meeting building fire protection standards and slowing down the spread of fire indoors. It can also wrap household distribution boxes and gas pipelines, reducing the fire hazards caused by electrical short circuits or gas leaks.
In the fields of transportation and industry: It is used as flame-retardant lining fabric for seats, instrument panels and wiring harnesses in the interiors of automobiles and high-speed trains, meeting the fire protection standards for transportation equipment and reducing the harm of toxic smoke in fire accidents. It can also be used as a flame-retardant coating for cables and wires to prevent the spread of flames to other areas when the lines catch fire.
High-temperature industrial auxiliary fields: In the metallurgy, chemical, and power industries, it is used as heat insulation covering fabric for high-temperature operations, temporary fireproof shielding for equipment maintenance, or simple wrapping materials for high-temperature pipelines. It can withstand short-term high temperatures and is easy to lay, ensuring operation safety.
