What are the raw materials of nonwoven fabrics?
As PetroChina and Sinopec began to build masks production lines to produce and sell masks, people gradually realized that masks are inextricably linked with oil. From Oil to Mask details the whole process of changing from oil to masks step by step. Petroleum distillation and cracking can produce propylene, propylene can be polymerized to produce polypropylene, and polypropylene can be further made into polypropylene fiber, which is also known as polypropylene fiber. Polypropylene fiber (polypropylene fiber) is the main fiber raw material for producing non-woven fabrics, but it is not the only raw material. Polyester fiber (polyester fiber), polyamide fiber (nylon fiber), polyacrylonitrile fiber (acrylic fiber), viscose fiber, etc. can be used to produce nonwoven fabrics.
Of course, in addition to the above chemical fibers, cotton, hemp, wool, silk and other natural fibers can also be used to produce nonwoven fabrics. Some people often think that non-woven fabrics are chemical fiber products at the mention of non-woven fabrics, which is actually a misunderstanding of nonwoven fabrics. Like the clothes and fabrics we usually wear, non-woven fabrics also have chemical fiber non-woven fabrics and natural fiber nonwoven fabrics, but chemical fiber non-woven fabrics are more common.
