Aramid sliver is used to make cut-resistant gloves for metal and glass processing.

Aramid 1414 nonwoven fiber sliver is produced by needle-punching aramid fibers into a nonwoven fabric, which is then cut to the dimensions required for each specific project. The resulting surface has a plush, velvety texture.

Characteristics of aramid 1414 nonwoven sliver fibers:

1. Heat Resistance and Flame Retardancy

It can withstand long-term operation in a high-temperature environment of 220°C without aging, and maintains its fabric strength even when continuously exposed to 240°C. The fibers begin to decompose only when the temperature exceeds 370°C, with noticeable carbonization starting around 400°C. This exceptional thermal stability stems from its highly robust molecular structure, enabling Aramid 1414 nonwoven sliver to retain both its physical properties and dimensional stability under extreme heat conditions.

The limiting oxygen index (LOI) of aramid 1414 nonwoven fiber strips is greater than 28, meaning they won’t sustain combustion when exposed to an open flame in air and will self-extinguish once removed from the ignition source. In the event of sudden exposure to extremely high temperatures, the fabric surface rapidly chars and thickens, creating a unique insulating barrier that effectively blocks heat transfer without cracking.

2. Outstanding Mechanical Properties

The most remarkable characteristics of para-aramid (1414) are its ultra-high strength and high modulus—its tensile strength exceeds 25 grams/denier, making it 5 to 6 times stronger than steel, 3 times stronger than glass fiber, and 2 times stronger than high-strength nylon industrial filaments. Meanwhile, its modulus is 2 to 3 times higher than that of steel or glass fiber, and an impressive 10 times greater than high-strength nylon industrial filaments.

3. Excellent chemical resistance

Aramid 1414 nonwoven sliver fabric is resistant to the corrosion of most inorganic acids, bases, and organic solvents. This exceptional chemical stability ensures that it maintains excellent performance even in harsh chemical environments, preventing degradation when exposed to common chemicals. Additionally, its resistance to hydrolysis and steam corrosion further broadens its applicability in humid, high-temperature settings. Moreover, the material exhibits outstanding radiation stability, offering superior protection against alpha, beta, X-ray, and ultraviolet radiation.

4. Eco-friendly and Safe

Aramid 1414 nonwoven sliver generates no molten droplets or toxic gases when exposed to fire, enhancing its safety in protective applications while posing no harm to human health or the environment.

Applications of Aramid 1414 Nonwoven Fiber Strips:

1. Security Protection Field

Used to manufacture specialized protective garments such as fire-fighting suits, chemical-resistant combat uniforms, furnace-front workwear, and welding workwear. In these applications, aramid 1414 nonwoven sliver can be processed into nonwoven fabric form or combined with other materials. When exposed unexpectedly to high temperatures, the fabric surface rapidly chars and thickens, creating a unique thermal insulation barrier that safeguards the wearer from heat-related injuries.

Used to manufacture protective gear such as bulletproof vests and bulletproof helmets. Aramid 1414 non-woven fiber slivers can also be used to make cut-resistant gloves, providing hand protection for workers in industries like machining, metal processing, and glass fabrication.

2. Industrial Application Fields

In high-temperature flue gas filtration applications across industries such as carbon black, cement, steel, and non-ferrous metals, the filter materials made from aramid 1414 nonwoven fiber strips can withstand continuous operating temperatures of up to 240°C and resist chemical corrosion. Additionally, their outstanding abrasion resistance ensures long service life even under heavy dust-loading conditions.

In terms of electrical insulation, insulating papers and felts made from aramid 1414 nonwoven roving materials—thanks to their outstanding high-temperature electrical insulation performance—are widely used for insulation protection in motors, transformers, and other electrical equipment.

3. High-tech fields

Aramid 1414 nonwoven fiber tow features low density, high specific strength, and high specific modulus, making it ideal for applications such as aircraft interior materials, cabin wall insulation, and aerospace sealing components. Not only does it reduce the weight of aircraft, but it also enhances flight safety while minimizing fire risks.

In the transportation sector, aramid 1414 non-woven sliver boasts properties such as high temperature resistance, high strength, and excellent abrasion resistance, making it ideal for manufacturing automotive hoses, tire cord fabric, brake pads, and other products.
