[0002] Non-woven fabric is made of directional or random fibers, and is called cloth due to its appearance and certain properties. Non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, non-combustibility, easy decomposition, non-toxicity, non-irritation, rich color, low price and recyclability. For example, polypropylene pellets are used as raw materials, and are produced by continuous one-step method of high temperature melting, spinning, laying, hot pressing and winding. During the production of non-woven fabric, the thickness of non-woven fabric is an important indicator for detecting product quality.
