Core Advantage (Most Prominent Feature): By adjusting fiber twist, using polyester fibers with hollow/irregular cross-sections, or applying air expansion treatment during spinning, more gaps are created inside the thread. This gives the thread a fluffy and plump appearance, along with a lighter and softer touch.
Inherits Basic Advantages of Polyester:
- High strength: Not easy to break, suitable for sewing scenarios requiring a certain degree of tensile force;
- Chemical resistance: Resistant to acids, alkalis, and detergents, with no easy deformation or fading after washing;
- Good stability: Low shrinkage, and better dimensional stability than natural fiber threads (e.g., cotton thread).
Unique Functions:
- Strong coverage: The fluffy thread can cover the fabric surface more evenly during sewing/weaving, reducing stitch marks and improving the appearance of finished products;
- Moderate elasticity: Some high-loft threads gain a certain elasticity through process adjustment, making them suitable for fabrics that require slight stretching (e.g., knitwear);
- Auxiliary warmth retention: The gaps in the thread can trap air when used in textiles, enhancing the fabric’s warmth retention (e.g., plush toys, linings of winter clothing).
