1. What Is Filament Yarn Nylon 6?

Filament Yarn Nylon 6 is a continuous synthetic fiber made from polycaprolactam through a polymerization process. Unlike staple fibers, filament yarn consists of long, continuous strands, giving it superior strength, uniformity, and smoothness.

Nylon 6 filament yarn is widely recognized for its balance of performance, cost-efficiency, and adaptability. It can be produced in various forms such as FDY (Fully Drawn Yarn), POY (Partially Oriented Yarn), and DTY (Drawn Textured Yarn), making it suitable for diverse end-use requirements.


2. Chemical Structure and Manufacturing Process

2.1 Chemical Structure

Nylon 6 is formed through ring-opening polymerization of caprolactam. This structure allows for:

  • High molecular flexibility
  • Excellent impact resistance
  • Superior dye absorption

2.2 Manufacturing Process

The production of Filament Yarn Nylon 6 generally includes the following steps:

  1. Polymerization of caprolactam
  2. Melt spinning through spinnerets
  3. Quenching and solidification
  4. Drawing and orientation
  5. Texturing or finishing (if required)

3. Key Properties of Nylon 6 Filament Yarn

Property Description
High Tensile Strength Suitable for demanding industrial and textile applications
Excellent Elasticity Provides resilience and shape retention
Abrasion Resistance Ideal for high-wear products
Superior Dyeability Achieves vibrant and uniform colors
Moisture Absorption Improves comfort compared to polyester

4. Types of Nylon 6 Filament Yarn

  • FDY (Fully Drawn Yarn): High strength, ready for direct weaving or knitting
  • POY (Partially Oriented Yarn): Used as an intermediate yarn for texturing
  • DTY (Drawn Textured Yarn): Offers bulkiness and elasticity
  • High Tenacity Yarn: Designed for industrial-grade performance

5. Major Applications Across Industries

5.1 Textile and Apparel

  • Sportswear and activewear
