Ultra-high molecular weight polyethylene fiber filtering cloth

Abstract

The invention discloses ultra-high molecular weight polyethylene fiber filtering cloth which is characterized by being prepared from ultra-high molecular weight polyethylene fiber warp and ultra-highmolecular weight polyethylene fiber weft in a woven manner, wherein filtering holes are formed between the ultra-high molecular weight polyethylene fiber warp and the ultra-high molecular weight polyethylene fiber weft. The ultra-high molecular weight polyethylene fiber filtering cloth is high in precision, high in loading capacity and good in tension resistance, the service life of the filteringcloth is 3 times or more than 3 times of that of a chemical fiber, the dry heat shrinkage rate of the filtering cloth is 2% or smaller than 2%, the acid / alkali resistance, the wearing resistance and the tension resistance are improved, the service life is prolonged, the use range of the filtering cloth is widened, the filtering quality is improved, and the filtering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of filter cloth production, in particular to an ultra-high molecular weight polyethylene fiber filter cloth. Background technique [0002] With the advancement of science and technology, the development of industry, the widespread use of filter press and filter equipment in industry has also led to the wider use of various filter cloths in industrial production. Industrial filter cloth is a filter medium woven from natural fibers and synthetic fibers, and is mainly used for solid-liquid separation and gas-solid separation. Synthetic fibers mainly include polypropylene, polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used, mainly for solid-liquid separation. The generalized industrial filter cloth also includes various metal materials such as stainless steel wire, nickel wire, brass Silk. The industries that can use filter cloth now include: pharmaceutical manuf...
