Let me share with you the little knowledge of mechanical stretch fabric.

　　Stretch fabrics, outdoor sports fabrics: Good stretch fabrics continue to promote the convenience, speed, and effectiveness of outdoor activities to protect muscles from power consumption during stretching. The elasticity of the fabric keeps clothing in sync with the rhythm of exercise, on the basis of protecting the body surface , To give greater play to the ability of human beings to break through the limits.

　　There are roughly the following types of stretch fabrics:

　　1. Polyester coated spandex yarn, the most common. The rebound is good, but the price is expensive.

　　2. T400 and PTT types are generally used for woven fabrics.

　　3. Ordinary DTY fiber is adjusted in the process, and the elasticity is about 22-25%. The most cost-effective.

　　4. Some so-called high-elastic yarns and polyester yarns can have a little stretch of over 30%.
