Characteristics and uses of aramid blended yarn

Characteristics and uses of aramid blended yarn

1.1 Characteristics of Aramid Fiber

1.1.1 Good mechanical properties

Aramid is a flexible polymer material. Its low stiffness and high elongation properties make it the same spinnability as ordinary fibers. It can be processed into various fabrics or non-woven fabrics by conventional spinning machines, and the aramid fabric is wear-resistant and tear-resistant. , can be widely used in labor protection, military production and other special fields.

1.1.2 Excellent flame retardant and heat resistance

Aramid fiber is a kind of flame retardant fiber, its limiting oxygen index LOI value is ≥28%, it is a flame retardant fiber, so the aramid fiber will not burn, melt or produce molten droplets in the air, and does not emit harmful gases and does not support combustion, is self-extinguishing.

1.1.3 Stable chemical properties

Aramid fiber can be used for a long time at a high temperature of 220 ° C without aging, its electrical properties and mechanical properties can be maintained for 10 years, and its dimensional stability is excellent.

1.1.4 Radiation resistance

Aramid fiber has excellent radiation resistance to α, β rays and ultraviolet rays. For example, when the β-ray radiation amount is accumulated to 1000Mrad, its intensity remains basically unchanged.

1.1.5 Application of Aramid Fiber

Aramid fiber can be used in various aspects of the national economy such as aerospace, electromechanical, construction, automobile, sporting goods, etc. It is mainly used for labor protection (fire suits, fire boots, fire bags, etc.) It is a new type of high-tech synthetic fiber, which has the characteristics of ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight.

1.2 Properties of flame retardant viscose fibers

1.2.1 Permanent flame retardant properties

Flame retardant viscose fiber burns with almost no flame, and goes out in a very short time, neither after burning nor smoldering.

1.2.2 Excellent thermal insulation performance

Flame retardant viscose fiber can effectively prevent the transfer of high temperature heat radiation. The fiber does not shrink or deform at high temperature.

1.2.3 Anti-arc and anti-static properties

Flame retardant viscose fiber maintains the original natural antistatic properties of viscose fiber.

1.2.4 Hygroscopicity

Clothing made of flame retardant viscose is comfortable and breathable to wear. In a high temperature environment, it is conducive to the discharge of sweat.

1.2.5 Excellent dyeability

Flame retardant viscose fiber has the characteristics of easy coloring, bright dyeing and good color fastness of natural fibers.

1.2.6 Green environmental protection

The flame retardant viscose fiber is made of regenerated natural plants, and the waste can be degraded naturally, which meets the requirements of environmental protection. Phosphorus flame retardant also meets the EU flame retardant halogen-free requirements.

1.2.7 Application of flame retardant viscose fiber

Flame-retardant viscose fiber is a new high-tech fiber material with flame-retardant and anti-droplet properties. Compared with synthetic polyester flame retardant fibers, it not only ensures the excellent physical properties of the fibers, but also realizes the characteristics of low smoke, non-toxicity, no peculiar smell, and no melting and dripping. With the advancement of mandatory flame retardant regulations at home and abroad and the improvement of people's awareness of fire safety, the application scope of flame retardant textiles is expanding, extending to household, underwear and other fields, and the requirements for flame retardant textiles have also expanded from simple protection to pursuit of more Optimum comfort, breathability and performance.
