Aramid 1313 mesh fabric is used as a reinforcing liner for high-temperature hoses.

Aramid 1313 grid fabric refers to a fabric with a mesh-like structure, made from Aramid 1313 fibers using specialized techniques such as warp knitting.

Characteristics of Aramid 1313 Mesh Fabric:

1. High-Temperature Stability: It can be used continuously in high-temperature environments up to 220°C without aging. The material exhibits excellent thermal dimensional stability; even when briefly exposed to temperatures as high as 300°C, it neither melts, softens, nor becomes brittle—decomposition only begins when the temperature exceeds 370°C.

2. Inherent Flame Retardancy and Self-Extinguishing Properties: Aramid 1313 is a permanently flame-retardant material with a limiting oxygen index (LOI) exceeding 28%. Since the oxygen content in air is approximately 21%, it is inherently difficult for this material to sustain combustion in air, exhibiting non-flammable and non-supportive characteristics—meaning it will automatically extinguish once removed from the ignition source. This exceptional flame retardancy stems from the material’s unique, intrinsic chemical structure, which remains stable even after washing or prolonged use.

3. Electrical Insulation: Aramid 1313 has a very low dielectric constant, enabling it to maintain excellent and stable electrical insulation performance even under harsh conditions such as high and low temperatures, as well as high humidity.

4. Chemical Stability: Its chemical structure is highly stable, enabling it to withstand corrosion from most high-concentration inorganic acids, bases, and chemical solvents, as well as resisting hydrolysis and steam erosion.

5. Excellent Mechanical Properties: Aramid 1313 fiber itself boasts high strength, superior abrasion resistance, and outstanding tear resistance. When fabricated into mesh fabric, its interwoven grid structure ensures consistent tensile strength in both warp and weft directions, fully leveraging the inherent high-strength characteristics of aramid fibers. At the same time, it retains excellent flexibility and ease of processing.

Applications of Aramid 1313 Mesh Fabric:

1. Security Protection Field

Firefighting protective gear: Used to manufacture firefighters' fire-fighting suits and emergency rescue uniforms. Leveraging their high-temperature resistance, flame retardancy, and non-dripping properties when exposed to fire, these garments provide firefighters with critical thermal protection in hazardous fire environments.

Military and police combat training uniforms: Designed for crafting combat and training attire for soldiers and law enforcement officers, offering fire resistance and basic thermal insulation protection.

Industrial protective clothing: Used as high-temperature workwear in industries such as oil, natural gas, electricity, and metallurgy—where there are risks of extreme heat or flames—to safeguard worker safety.

2. Industrial Manufacturing and Enhancement Field

High-temperature hose-reinforcing fabric: This is a crucial and classic application of aramid 1313 mesh cloth. It is used as a lining or reinforcing layer for various automotive hoses—particularly those with large diameters, straight sections, and high-temperature/high-pressure resistance—as well as silicone tubes. Its mesh structure ensures uniform tensile strength in both the warp and weft directions, while also providing excellent adhesion to rubber. This combination effectively withstands internal pressure and significantly enhances the durability of the hoses.

High-temperature filtration materials are essential for managing high-temperature flue gases in industries such as steel, cement, and carbon black production. Aramid 1313 mesh fabric serves as the base material for high-temperature filter bags, ensuring stable filtration efficiency and extended service life even under harsh, elevated-temperature conditions.

3. High-end Technology and Specialized Industrial Fields

Electrical insulation materials: Leveraging their excellent electrical insulation properties, these materials are used in insulating components of electrical equipment such as motors and transformers, including insulating paper and bushings.

Aerospace: Used in aircraft fuel tanks, firewalls, honeycomb structural components, and select interior materials, meeting their stringent demands for lightweight design, flame retardancy, and high-temperature stability.

Dome Shells and High-End Audio: Aramid 1313 material is also used to manufacture high-quality speaker diaphragms (dome shells), as its high internal resistance and exceptional stability help enhance sound quality.
