Sss Spunbond Nonwoven Production Line
SSS: Spunbond non-woven fabric + spunbond non-woven fabric + spunbond non-woven fabric = 3 layers of fiber web hot rolled; S non-woven fabrics, SS non-woven fabrics, SSS non-woven fabrics can be produced, according to non-woven fabrics Cloth performance can be used for: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths Cloths, tablecloths, bed sheets, bedspreads; clothing linings, fusible linings, wadding, shaped cotton, various synthetic leather base fabrics, industrial filter materials, insulating materials, cement packaging bags, geotextiles, covered cloths, crop protection cloths, seedling cloths , Irrigation cloth, thermal insulation curtain, other space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. Mainly used in disposable hygiene products industry, medical health industry, beauty care and other industries.In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after being discarded is only 10% of that of the plastic bag.
