Polyester ITY FDY+POY Composite Filament

Product Features
Polyester ITY FDY+POY Composite Filament is an innovative hybrid yarn engineered by integrating Fully Drawn Yarn (FDY) and Partially Oriented Yarn (POY) through advanced composite texturing technology. This dual-component structure combines the high tenacity and dimensional stability of FDY with the exceptional elasticity and bulkiness of POY, resulting in a lightweight, durable, and versatile filament. The intermingling process ensures uniform cohesion between FDY and POY layers, enhancing tensile strength (≥4.5 cN/dtex) and reducing fraying. The yarn features a soft, silk-like hand feel, superior moisture-wicking properties, and excellent dye uniformity, achieving a colorfastness rating of 4-5 on the ISO scale. Customizable in denier (50D–300D), luster (semi-dull to bright), and twist levels, it supports tailored performance for diverse applications.

Application Scenarios
This composite filament is ideal for high-end textiles requiring a balance of strength and elasticity. In apparel, it is widely used in stretchable fabrics for sportswear, swimwear, and lingerie, offering comfort and shape retention. Its moisture-management properties make it suitable for activewear and outdoor gear, while its drape and sheen enhance luxury eveningwear and scarves. In home textiles, it is applied in upholstery, curtains, and bedding due to its resistance to abrasion and UV degradation. Technical sectors, including automotive interiors and industrial fabrics, leverage its durability and low-shrinkage properties (<2.5%). Additionally, eco-focused variants incorporating recycled PET cater to sustainable fashion and eco-certified product lines.

Product Advantages
The ITY FDY+POY Composite Filament outperforms conventional polyester yarns through its synergistic structure. The FDY core ensures robust mechanical performance, reducing breakage during high-speed knitting or weaving, while the POY sheath provides elasticity (up to 25% elongation) without compromising recovery. Compared to single-component yarns, it reduces pilling by 30% and enhances weaving efficiency by 15% due to reduced filament separation. Its rapid dye uptake lowers energy consumption in dyeing processes, aligning with eco-friendly production standards. The hybrid design also allows cost optimization by minimizing material waste. With customizable functional additives—such as antimicrobial or flame-retardant agents—it meets stringent industry regulations. Offering a premium aesthetic and extended lifecycle, this filament ensures superior value for technical and fashion-driven markets alike.
