Common synthetic fiber used in underwear fiber raw materials

The common synthetic fibers used in underwear mainly include polyester, nylon, spandex, etc. Polyester and nylon have good elasticity, fastness, and fastness to wash, wash, and dry. However, due to poor moisture absorption, they do not absorb sweat when worn. This kind of stuffy sensation, and it is prone to static electricity, it is very dusty, so it is not suitable for making intimate underwear. However, it can be blended or interlaced with cotton, hemp, wool, etc., to improve the elasticity, wrinkle resistance, heat resistance, and shape stability of the underwear; it can also be applied to underwear, bras, and other make-up underwear in the form of lace or outer fabric. In order to enhance its flexibility, supporting force and correction, but should pay attention to the direct contact with the skin, try not to use such synthetic fabrics.

Spandex fiber has excellent elasticity, its elongation is as high as 500%~800%, and it has excellent fatigue resistance and high elastic recovery. However, spandex is not generally used alone, but it is incorporated into fabrics in small amounts. It can be used with any fabric (including wool, hemp, silk, and cotton) to increase the fabric's closeness, elasticity, and loose natural characteristics, such as "Wool + Lycra" fabrics. Good elasticity, and better fit, shape retention, drape, and washability; "cotton + Lycra" fabric not only has the comfort and breathability of cotton fiber, but also makes the fabric more fit, fit, soft and comfortable Wait.
