It is highly durable, comfortable, and typically used in sportswear, activewear, thermal garments, and home textiles to enhance warmth and reduce weight.
Key Features and Benefits
- Thermal Insulation: The core structure traps air to retard heat loss in cold environments.
Common Applications
- Apparel: Thermal underwear, outdoor and performance activewear, and everyday apparel.
- Home Textiles: Cushions, pillows, quilts, and blankets.
- DIY & Craft: Chunky, tubular yarn used for crocheting baskets, bags, and rugs.
Types of Hollow Polyester
- Hollow Filament Yarn: Used for clothing and performance fabrics due to its smooth feel and insulating properties.
- Hollow Fiber Filling: Used for high-resilience pillows and insulation in outerwear.
- Hollow Tubular Yarn: A, often thicker, "knitted" polyester cord used for DIY crafts and accessories.
