Modern textile technology improves the elasticity of woven fabrics and expands their applications through the following methods:
1. Blending with elastic fibers: Adding 5%-10% spandex (such as Lycra) can significantly improve elasticity. For example, the stretch rate of stretch denim can reach 20%-25% (data source: International Federation of Textile Manufacturers).
2. Special weaving processes:
- Stretch woven fabrics: Using pre-shrinked yarns or elastic warp yarns gives the fabric bidirectional stretching capability;
- Twill/satin weaves: Increasing flexibility by changing the distribution of interlacing points.
3. Finishing techniques: Such as mechanical pre-shrinking or chemical relaxation treatments, can improve fabric extensibility.
