Nonwoven fabrics (also known as Non-Woven fabrics) are made of oriented or random fibers. It is called a cloth because of its appearance and certain properties. The non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity or irritation, rich color, low price, recycling and the like. For example, the polypropylene (pp material) granules are mostly adopted as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying a line and hot-pressing coiling.
The non-woven fabric has no warp and weft, is very convenient to cut and sew, is light in weight and easy to shape, and is popular with hand fans. Because it is a fabric formed without spinning a woven fabric, it is formed by orienting or randomly arranging textile staple fibers or filaments to form a web structure and then reinforcing them by mechanical, thermal or chemical means. The fabric is not interwoven and knitted by yarns one by one, but the fibers are directly bonded together by a physical method, so that when a user takes the fabric into the clothes, the user can find that one thread end cannot be drawn out. The non-woven fabric breaks through the traditional spinning principle and has the characteristics of short process flow, high production rate, high yield, low cost, wide application, multiple raw material sources and the like.
