What are the main ingredients of non-woven fabrics?

The exact name of non-woven fabric should be non-woven fabric. Because it is a kind of fabric that does not need to be spun and weaving, it just oriented or randomly brace the textile short fibers or filaments to form a fiber network structure, and then use machinery It is reinforced by methods such as, heat bonding or chemical. Nonwovens break through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials. The main uses can be roughly divided into: (1) Medical and health cloth: surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.; (2) Home decoration cloth: wall coverings, table cloths, bed sheets, Bed cover, etc.; (3) Follow-up cloth: lining, fusible lining, wadding, shaped cotton, various synthetic leather base cloth, etc.; (4) Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, Covering cloth, etc.; (5) Agricultural cloth: crop protection cloth, seedling cloth, irrigation cloth, thermal insulation curtain, etc.; (6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. The three major fibers used in the production of non-woven fabrics are: polypropylene (62% of the total), polyester (24% of the total) and viscose fiber (8% of the total). Between 1970 and 1985, Viscose fiber has the most applications in production, but in the last 5 years, in the field of hygienic absorbent materials and medical textiles, the application of polypropylene fiber and polyester fiber has begun to dominate. In the early production market, the amount of nylon was large, from Starting in 1998, the amount of acrylic fiber began to rise, especially in the field of artificial leather manufacturing.
