What is the difference between woven and non-woven felt?
Non woven fabrics are fabrics that have not been woven. The viscose for chemical fiber is subjected to high temperature and high pressure to form a base cloth. Then, a layer of hot melt adhesive is placed on the surface of the base fabric through a coating machine, and then dried to form the Non Woven Fabric we use. The commonly used equipment for woven fabrics are key rod looms and water jet looms, which make polyester into base fabrics through weaving.
