Para-aramid Short Fiber – STAPLE

Definition by DuPont: PRECISION-CUT, SHORT FIBERS

Kevlar® Staple consists of precision-cut, short fibers, ¼ inch or longer. It is used to manufacture spun yarns, which provide enhanced wear resistance and comfort vs. filament yarns. Because spun yarns are discontinuous fibers, their applications generally take advantage of the barrier properties of Kevlar®, rather than the tensile and modulus properties.

Kevlar® staple is also used in felts and nonwovens to increase thermal insulation and vibration-dampening properties. Other applications include thermoset and thermoplastic resin systems where Kevlar® increases strength and wear resistance over a wide range of temperatures.

Define: Kevlar® & Nomex® Fiber

These two brands are belong to DuPontTM. They are most used ARAMID material, which Kevlar® is para-aramid and always has a natural color of yellow, on the other hand, Nomex® is meta-aramid and has a natural color of white.

Kevlar® has successfully emerged out as one of the ultra high-performance fiber since it’s been first introduced by Stephanie Kwolek on 1971, and was registered by DuPont as a famous para-aramid material commercial brand. This magic fiber has various amazing features: long-term working in high-temperature environment, high tensile load, low elongation.

Advanced Properties of Kevlar® | Para-Aramid fiber

High strength to weight ratio
Low elongation to break
Low thermal shrinkage
Good heat & flame resistance
Self-extinguishing flame retardant properties
Good chemical resistance
Excellent bulletproof/ballistic properties
High cut resistance (not so easy to cut off than normal fibers)
UV resistance good (ONLY on black and other non-natural color fiber)
UV resistance poor (natural, and please notice this is the MAIN WEAKNESS of aramid fiber)

Important Tips

If you are developing a stronger yarn for the first time that considering of para-aramid or meta-aramid, then you should have figure out the basic knowledge of these materials. And there are mature and well-developed goods which have been produced for years, like aramid thread(para & meta) like 20S2, 20S3, 40S2, and 40S3. Based on these thread/yarn, there are several manufacturers that can provide varieties of woven fabric for firefighting and protective suits, thermal protective felt, nonwoven fabrics and uni-directional fabrics. They have different applications. The quick way to find the best suitable material is to ask me directly via email or WhatsApp/WeChat.
