Inspection method and application of filter material "fiber"

In the production process of the filtration industry, the main composition of the filter bag is that there are many types of fiber fibers, and the most used in our company are NOMEX, PPS aramid, polyester, polypropylene, P84... Some are used in industry, and some are used for civil use. Polyester and polypropylene are the most used for filtration in the industrial and food industries. Today, we mainly introduce the performance and method of polyester fiber.


Polyester is referred to as PET, poly fiber, the industry is used to call it "PE filter bag" will often ignore "PET", in fact, the Chinese name of PE is polypropylene, PET Chinese name is poly vinegar, and our production of materials in the polymer fiber in liquid filtration and separation of the most widely used. The material is mainly from a Sinopec Yizheng Fiber Co., LTD.


Yizheng Chemical Fiber is a wholly owned subsidiary of Sinopec. The company was founded in 1978, mainly engaged in the production and sales of polyvinegar products, including polyester staple fiber products first in the world. Yizhua is the R&D and production base of ultra high molecular weight polyene fiber and aramid of Sinopec. PET polymerization capacity 2.2 million tons/year Product fiber is divided into three categories:

Cotton type: Linear density 0.8~2.1dtex Medium long type: linear density 22~3.2dtex Wool type: linear density 3.3~6.0dtex fiber quality control focus on supplier management/import inspection link: When the product at the source control is in place, the problem will be found and solved in the first time that the quality of the finished product will be natural.
