Ultra-fine Denier Anti-pilling Polyacrylonitrile Fiber

2025-03-17News 830

Reasons for recommendation

The fiber is slender and soft with a delicate and skin-friendly touch akin

to cashmere. It provides excellent thermal-retention and anti-pilling

properties. The fabric has excellent shape retention, being able to

maintain a smooth appearance for a long time, and is easy to handle. lt

is an ideal choice for high-end use of ultra-thin and thermal-retention cloth.

Preparative technique

The polyacrylonitrile was copolymerized with the first, second and third monomers using an aqueous phase suspensionpolymerization technique, and then spun through a wet spinning process with a high-precision spinneret.

Q: Do you know about the comprehensive advantages of ultra-fine denier anti-pilling polyacrylonitrile fiber?

A: By process innovation and equipment upgrading, the section of ultra-

fine denier anti-pilling polyacrylonitrile fiber has been transformed from a traditional broad-bean shape to a subrounded shape, which is more conducive to downstream combing and spinning processes. The fiber has better softness,a light and delicate touch, and anti-pilling properties. Its large specific surface are a and moisture absorption capacity which is twice that of ordinary fibers impart excellent wearing comfort to clothing.
