The characteristics and applications of different material types of non-woven fabrics

(1) PP non-woven fabric is also called polypropylene non-woven fabric or spunbonded non-woven fabric. It is characterized by impermeable and air-impermeable above 80g. When the square gram is thin, the main raw material is polypropylene. The shelf life of water is relatively short, and it will decompose naturally, so the green color can also be processed into waterproof, flame retardant and other functions according to its application field. Common application areas are the production of supermarket shopping bags, sofas, handbags and printed packaging materials. (2) Spunlace non-woven fabric The so-called spunlace refers to the production method. The process is to spray a high-pressure fine water stream onto the fiber web, so that the fibers are entangled with each other, so that the fiber web can be fabricated. Its main raw materials are viscose, polyester and wood pulp. The more viscose ingredients, the more expensive in general. Its main characteristics are soft, delicate, hydrophilic, and comfortable to the touch. The main areas of application are home textiles, sanitary cloths, and valuables wiping products. For example, one-time makeup wipes commonly found in supermarkets are typical products. (3) Needle-punched non-woven fabric Strictly speaking, it can be called this only if it has been hot-rolled or hot-air processed. The heat-sealing non-woven fabric here refers specifically to the hot-air non-woven fabric, most of which are short fibers, and low-melting-point fibers are uniformly mixed together and dried by hot air, such as ES fiber, 4080, etc., and its main application areas are clothing, For home textiles, shoes and hats, and automotive interior materials, high-grade carpets are common.
