Lycra fabric belongs to the mid to high end elastic fiber material category, positioned based on its unique chemical structure and production process, and is widely used in the field of high-quality clothing.
Grade positioning and characteristics of Lycra fabric
The core value of Lycra fabric lies in its excellent elasticity performance. As a spandex fiber developed by DuPont in the United States, its stretchability can reach 500%, and it has excellent resilience and long-lasting shape retention ability. In the classification of textiles, Lycra is usually classified as a mid to high end grade, mainly for the following reasons:
Material characteristics and technological advantages.
The molecular structure of Lycra has been specially designed, with a rebound rate of up to 99% (at 50% elongation), far exceeding that of ordinary spandex.
Support high temperature setting treatment at 195 ℃ to ensure better stability of blended fabrics during dyeing and processing.
High end products with environmental certifications such as OEKO-TEX Standard 100 achieve zero formaldehyde residue in the production process.
Market classification standards.
High end grade: containing over 95% Lycra fiber, using black technologies such as 3D weaving and graphene thermal conductive film.
Mid end: Lycra accounts for 65-80% and is commonly used in professional sportswear and shapewear.
Basic version: Lycra content is less than 50%, mostly used for daily clothing of fast fashion brands.
Category application differences.
Luxury brand swimsuits, aerospace grade bodysuits, and other ultra high end products use 100% Lycra fiber and nano antibacterial technology.
Mid end products are commonly found in professional series of sports brands such as Nike and Adidas, and have maintained 90% elasticity after 100000 tensile tests.
Key indicators for identifying high-quality Lycra
Tag authentication: Genuine Lycra clothing comes with a triangular tag, which is the core quality identification.
Fiber ratio: High end products clearly indicate Lycra content (such as ≥ 85%), while low-priced products often mix ordinary spandex.
Physical properties: High quality Lycra fabric has a shrinkage rate of less than 3% after 50 washes, and its wrinkle resistance is significantly better than blended materials.
