SRALON® Staple Fiber
Para aramid staple fibers for spun yarn and non-woven fabrics.
SRALON® Para-aramid filaments provides extremely high strength and modulus with light weight, also shows excellent flame and abrasion resistance.
SRALON® para-aramid staple fibers are made from filaments, which are washed, crimped and cut and then treated by surface treatment. With those unique properties both in chemical and physical, SRALON® staple fiber can perfectly meet all needs from fabric and yarn manufactures to produce protective workwear and variety of other personal protective equipment.
SRALON® staple fibers are widely used in textile application including high-end yarn, blended yarn, needle-spun felt and non-woven industry. Its essential but multiple linear density and fiber length provide more possibility for softness and comfort.
