It can be nylon-cotton elastic casual shirt fabric. The warp direction is nylon and spandex coated raw materials, and the weft direction is combed cotton yarn or artificial cotton yarn between 50 and 30 inches, and some of them are embedded with sliver. Because it is a warp elastic fabric, it is wrapped by nylon long fibers, so the elasticity can be excellent, and the warp shrinkage rate can reach about 40% (about 30% for general elastic fabrics). Because of the existence of nylon, it feels smooth and warm. I wonder if it's this kind of fabric. This kind of fabric is mostly casual shirts.
