The raw materials of the non-woven fabric are mainly PP granules, filler (main component is calcium carbonate), and color masterbatch (for coloring non-woven fabrics). The above materials are mixed in proportion and added to the non-woven fabric production line equipment, and are produced by high-temperature melting, spinning, paving, hot pressing and coiling in one step. In order to ensure the quality of the nonwoven fabric, the proportion of the filler is usually not higher than 30%.
The non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Widely used in the production of handbags and packing bags.
