It is a kind of fabric that does not need to be woven by spinning fabrics. It merely orients or randomly positions the textile staple fibers or filaments to form a web structure, and is then reinforced by mechanical, thermal adhesive or chemical methods. It directly utilizes polymer chips, staple fibers or filaments through a variety of web forming and consolidation techniques to create new fibrous products with a soft, breathable and planar structure. Simply put: It is not a single piece of yarn that is intertwined and knit together, but the fiber is directly bonded together by physical means, so when you get the stickiness in your clothes You will find that it is impossible to pull out the thread. Non-woven fabrics have broken through the traditional textile principles, and have the characteristics of short process flow, high production speed, high output, low cost, wide use, and many raw material sources.
