Spunbond nonwoven fabric

Non-woven fabrics mainly use PET (polyester) and PP (polypropylene) as the main raw materials. We mainly talk about PP non-woven materials. The common non-woven special material manufacturers in the domestic market are Shanghai Petrochemical, Guangzhou Petrochemical, Luoyang Petrochemical, Liaoyang Petrochemical, Fushun Petrochemical, Jinan Refinery, etc. The imported materials are mainly Dalin, South Korea, and EXXEN.

Guangdong has the largest non-woven fabric output, so Guangzhou Petrochemical has the absolute advantage of geographical advantage. This production of non-woven special material CS820 is also very representative in China. This product is produced by Japan's Mitsui Oiled HYPOL production technology with world-class level. It has high fluidity, narrow molecular weight distribution, good processing performance, non-toxic and odorless characteristics. Products are widely used in composite filaments, staple fibers and textiles .
