1. Filter cloth classification

   1. According to the performance of the filter cloth, the filter cloth can be divided into polyester, polypropylene, nylon, vinylon, cotton, new high-efficiency materials, etc.

   2. There are two methods of weaving.

   (1) Woven fabric, including polyester, polypropylene, nylon, vinylon, cotton, etc. There are several weaving methods for filter cloth, plain weave, twill weave, satin weave, double weave, etc.Filter Press Filter Cloths Manufacturers

   (2) Non-woven fabrics, including non-woven fabrics, geotextiles, filter felts, etc. Methods include spunbond method, acupuncture method, water weaving method, etc.



   (3) The wire material of filter cloth is divided into three types: monofilament, long fiber composite wire, and short fiber.

   2. Products

There are hundreds of models of    filter cloth, which cannot be listed one by one. Among them, polyester fiber and polypropylene fiber are the most widely used.

   (2) Non-woven fabric

   7. The non-woven fabrics are mainly made of polyester and polypropylene. After acupuncture, carding, and fabric core are added into the woven cloth interlayer, and then subjected to bidirectional nuclear treatment, the airflow forms a net-like needle-punched composite cloth. The filter cloth has a three-dimensional structure. After heat setting and singeing, most of the surface is treated with chemical oil. Make the surface of the filter cloth smooth and the pores evenly distributed. From the surface, the product density is good, the surfaces on both sides are smooth, and the permeability is good.

   8. Filter felt. After thermal trimming, ablation or coating treatment, the surface is smooth and smooth.

   9. Geotextiles are widely used in construction, engineering, bridges, roads and other fields.
