What is polyimide knitted fabric?
Polyimide (PI, P84) knit fabric is knitted with polyimide (PI, P84) yarn which is ring spun from polyimide (PI, P84). Imine (PI, P84) is a type of polymer with imide repeating units. It has wide application temperature (-169℃~300℃) and chemical resistance. Corrosion resistance, high strength and other advantages. The production process of polyimide (PI, P84) knitted fabric is spinning - weaving - dyeing - finishing. Polyimide (PI, P84) knit fabric has excellent flame retardancy, high temperature resistance and soft feel, it combines the functions of warmth retention, antibacterial, and native far infrared, so it is widely used in protective clothing, racing flame-proof clothing, flight suits, and the production of armored units. It is the most ideal material for making protective clothing for armored forces, flame-proof racing suits, flight suits and other fire-resistant and flame-retardant clothing. It can also be used to make comfortable and warm functional clothing, such as military clothing, medical sanitary clothing, and the elimination of defects. Body odor casual clothes, special clothing to prevent biological and chemical weapons, medical hygiene Protective clothing, high-efficiency smoke protection masks, used as insulation inside firefighter jackets, P84's soft hand feel properties and heat-resistant and non-flammable properties are the reasons for its use in protective clothing.

Polyimide (PI, P84) knit fabric application
Polyimide fiber has good spinnability and can be made into textiles for various special occasions. Due to its high and low temperature resistance, flame retardancy, no dripping, self-extinguishing when removed from fire, and excellent temperature insulation, polyimide fiber thermal insulation protective clothing is comfortable to wear, has good skin adaptability, and is permanently flame retardant. It is also dimensionally stable, safe and has a long service life. Compared with other fibers, it is also an excellent thermal insulation material due to its low thermal conductivity. In terms of labor protection clothing, our country's metallurgical sector needs 50,000 sets of heat-insulating, breathable, soft flame-retardant work clothes every year, and the hydropower, nuclear industry, geology and mining, petrochemical, oil field and other departments need 300,000 sets of protective clothing annually, and about 300 tons of high-temperature resistant and flame-retardant special protective clothing fiber.
Polyimide clothing fiber is a
brand-new type in the global textile industry. Its excellent performance originated from the demand for new materials in aerospace. It integrates functions such as warmth retention, antibacterial, and native far-infrared. It is a subverting tradition.
Brand
new clothing material for clothing fabrics. Can be used to make extreme cold protection Warm, antibacterial fabrics, far-infrared health care and other functional products.
Non-woven fabrics made of polyimide fiber are the most ideal fiber materials for making fire-resistant and flame-retardant clothing such as protective clothing for armored forces, flame-proof racing suits, and flight suits. This kind of nanofiber
nonwoven fabric can also be used to make comfortable and warm functional clothing, such as military clothing, medical hygiene clothing, and elimination clothing. Casual clothing for bad body odor, special clothing to prevent biological and chemical weapons, medical health protection clothing, high-efficiency smoke protection masks, etc. Needle-punched felt made from
P84
polyimide fiber is quilted onto lightweight
P84
fabric and used as insulation on the inside of a firefighter's jacket.
P84's soft hand feel properties as well as its heat resistance and
non-flammability are the reasons for its use in protective clothing.
P84
polyimide fiber is mainly used in fabric blends with the main goal of providing optimal protection and wearing comfort. The main mixing partners are FR viscose and para-aramid. Fabric weights from 175 g/m2, different mix ratios and different structures can be perfectly adapted to each specific application. These fabrics are used as outer shells for suits and jackets for firefighters, military and industry. Testing confirmed no afterburn, minimal smoke, and no formation or emission of toxic substances.
Polyimide knit fabric is used in personal protective equipment (PPE), including firefighting suits, hood cover and gloves, Polyimide
P84
fiber provides thermal protection at a lighter weight. The unique shape of Polyimide
P84
enables your personal protective clothing or personal protective equipment (PPE) to provide an excellent barrier against these harmful particles while maximizing airflow, ensuring total protection.Textiles using polyimide
P84
fibers have the amazing ability to allow the skin to breathe while resisting high temperatures and the surrounding environment. It allows air to flow freely, supporting the body's natural cooling system and reducing the threat of dangerous heat stress to firefighters and other professionals working in extreme temperature environments.
