polyester filter cloth
Polyester filter cloth long fibre industrial fabrics are woven by twisting loose filaments, which enhances the breaking strength of the fabrics. The strength of the twisted industrial fabric is more than one times stronger than the warp and weft strength of the industrial fabric made of loose filaments. Polyester long fibre has a smooth surface, good abrasion resistance and high strength, and after twisting, it has higher strength and better abrasion resistance. Thus, the fabric has good air permeability, fast water leakage and easy to clean. This material is not suitable for easy viscous filtration products. Polyester filament has higher strength than polyester staple fibre, stronger water leakage performance and better abrasion resistance.
Polyester staple fibre raw material structure is short and hairy, and polyester long fibre, raw material is long and smooth, by twisting polyester filament than staple fibre breaking strength is high, due to the material is smooth, weaving in the finished product breathable, and polyester staple fibre due to the raw material hairy, weaving fabrics are dense, breathable and poor performance. Generally speaking, if you want to use polyester products, please select polyester staple fibre and long fibre according to the performance of the finished product. Material properties: acid resistance, alkali resistance. Abrasion resistance, corrosion resistance, good recovery, conductivity is poor.
Polyester filter cloth characteristics
1, polyester filter clothMaterial properties: acid resistance, weak alkali resistance. Abrasion resistance, corrosion resistance, very good recovery, conductivity is very poor. Heat resistance: 120 ℃, elongation at break (%): 20-50, breaking strength (g / d): 438, melting point (℃): 238-240, melting point (℃): 255 a 260. specific gravity: 1.38.
2, polyester filter cloth filter cloth classification: polyester long fibre filter cloth, polyester staple fibre filter cloth.
3、 PolyesterFilter Press ClothFiltration performance: polyester long-fibre filter cloth has smooth surface, good abrasion resistance, high strength, higher strength and better abrasion resistance through twisting, thus the fabric has good air permeability, fast water leakage and easy cleaning. Polyester staple fibre filter cloth raw material structure is short and hairy, weaving out of the fabric is dense, particle retention is good, but stripping, air permeability is poor. Strength and wear resistance, water leakage is not as good as polyester long fibre filter cloth.
4, polyester filter cloth use: pharmaceutical, food, chemical, metallurgy, industrial filter press, centrifuge filter cloth and so on.
