Summary
Polybutylene terephthalate (PBT) yarns enhance the elasticity and recovery of woven fabrics, offering improved comfort in apparel and sportswear. Incorporating small amounts of PBT minimally impacts costs while significantly boosting fabric performance.
Area of Science:
- Textile Science and Engineering
- Materials Science
Background:
- Clothing comfort relies heavily on fabric elasticity and recovery, particularly for apparel and sportswear.
- Polybutylene terephthalate (PBT) yarns offer excellent elastic properties and high recovery after thermal treatment, making them suitable for enhancing fabric performance.
Purpose of the Study:
- To comprehensively review the application of PBT yarns in woven structures to improve the elastic properties of cotton-like fabrics.
- To investigate the influence of PBT yarn structure, weave design, and processing sequences on fabric properties.
Main Methods:
- Experimental investigation of fabric properties including physical, elastic, UPF, and comfort.
- Analysis of fabrics incorporating PBT yarns in the weft direction using basic and complex weaves.
- Evaluation of thermal treatment effects on PBT yarns and fabrics post-weaving.
Main Results:
- PBT-containing yarns demonstrate significant potential for creating lightweight, elastic fabrics.
- Incorporating small quantities of PBT yarns, particularly in specific fabric areas, effectively enhances elasticity with minimal cost increase.
- Thermal treatment is a key process for developing the desired elastic properties in PBT-enhanced fabrics.
Conclusions:
- PBT yarns are a valuable component for developing advanced textile materials with superior elastic characteristics.
- The strategic integration of PBT yarns and appropriate processing enables the cost-effective production of functional, comfortable, and durable fabrics.
- Partially elastic fabric areas can be achieved through targeted PBT yarn incorporation and thermal processing, offering innovative design possibilities.
