Product Introduction

Acrylic fiber is the trade name of polyacrylonitrile (PAN) fiber, mainly made from petroleum-cracked acrylonitrile (≥85%) through copolymerization and solution spinning, known as “artificial wool”. Light, bulky, warm, light-resistant and antibacterial with high cost performance, it is widely used in apparel, home textiles, outdoor and industrial fields as a large-volume synthetic fiber.

Types and Characteristics of Equipment

Type

Classified into staple, filament, high-shrinkage, anti-pilling and other varieties by form; divided into regular acrylic (acrylonitrile ≥85%) and modified acrylic (35%~85%) by composition, with core characteristics of softness, bulkiness, warmth superior to wool, excellent light resistance, bright dyeing, light weight and low cost.

Features

Excellent warmth: High bulkiness, about 15% warmer than wool, soft and non-itching; Best light resistance: The best sun resistance among synthetic fibers, with only 20% strength loss after 1 year of exposure; Light & strong: Density 1.16~1.18g/cm³, 1~2.5 times stronger than wool; Good dyeability: Bright color, good color fastness, with mold-proof, moth-proof and antibacterial properties; Disadvantages: Low moisture absorption (1%~2.5%), easy to generate static electricity, general wear resistance, not alkali-resistant.

Basic Principles and System Composition

Basic Working Principle

Using petroleum-cracked acrylonitrile as the main monomer (≥85%), adding a small amount of comonomers, polymerizing to generate polyacrylonitrile resin under catalyst, dissolving to make spinning solution, and making acrylic staple or filament through solution spinning, drawing and setting.
