HOY colored hollow crimped yarn series

HOY Colored Hollow Crimped Yarn Series: Technical Principles and Production Process Analysis

1. Company Background and Technical Advantages

Zhejiang Yuwei Chemical Fiber Co., Ltd. (established in 2005) is a modern high-tech enterprise integrating R&D, production, and sales, specializing in the development and innovation of differentiated and functional fiber products. As Custom Composite Differentiated Yarn Series Manufacturers and OEM/ODM suppliers, the company has become one of the benchmark enterprises in the domestic chemical fiber industry, relying on advanced production equipment, a strong R&D team, and a strict quality management system.

2. Technical Principles of HOY Colored Hollow Crimped Yarn Series

HOY (High Oriented Yarn) is a high-performance fiber produced through special spinning technology. The Colored Hollow Crimped Yarn series incorporates three core technologies:

• Hollow Structure: Special spinneret design creates continuous hollow cavities within the fiber, providing lightweight, high loft, and excellent thermal insulation.
• Crimping Process: Mechanical or thermal crimping enhances fiber elasticity and resilience, improving fabric softness and coverage.
• Dope Dyeing (Colored): Color masterbatch is blended with polymer before spinning, achieving molecular-level coloration with high color fastness and environmental benefits (reducing post-dyeing pollution).

3. Production Process

The production process at Zhejiang Yuwei Chemical Fiber Co., Ltd. includes the following key steps:

1. Raw Material Mixing & Melting: High-quality polyester (PET) or nylon (PA) chips are uniformly blended with color masterbatch and melted at high temperatures.
2. Hollow Spinning: Melt is extruded through annular spinnerets and cooled to form hollow fibers.
3. High-Speed Drawing & Orientation: Multi-stage hot roller drawing enhances molecular orientation, ensuring high fiber strength.
4. Crimping & Setting: Mechanical gears or high-pressure airflow create permanent 3D crimps.
5. Cutting & Packaging: Customized as staple fiber or filament, with strict quality control before packaging.

4. Product Advantages

• Functionality: Hollow structure provides thermal insulation for outdoor apparel and home textiles; crimping improves loft.
• Sustainability: Dope dyeing reduces water/energy consumption, aligning with global textile standards (e.g., OEKO-TEX®).
• Customization: Supports OEM/ODM in denier, color, crimp level, etc.

5. Industry Applications

This yarn series is widely used in high-end sportswear, home textiles, and automotive interiors, particularly in markets demanding "lightweight warmth." Zhejiang Yuwei Chemical Fiber Co., Ltd. continues to innovate in smart thermoregulation and antibacterial functional fibers.
