Industrial fabrics are an indispensable type of functional material in industrial production, mainly used in scenarios such as filtration, separation, protection, and reinforcement. Its core function is to achieve efficient separation of liquids from solids and gases from particles through physical or chemical properties, or to provide structural support and protection for equipment and products. From a technical perspective, the filtration performance of industrial fabrics depends on the pore structure of the material (such as polyester, polypropylene, nylon, etc.), the weaving method (plain weave, twill weave, satin weave), and the surface treatment process. For instance, woven filter cloth forms regular pores through the interweaving of warp and weft threads, which can precisely intercept particles larger than 5μm. The needle-punched felt filter cloth forms a three-dimensional filtration structure through the layering of fibers, which is suitable for scenarios with high precision and high dust holding capacity. In terms of application scenarios, industrial fabrics cover multiple fields: in the environmental protection industry, they are used for flue gas dust removal (such as bag filters in power plants and steel mills) and sewage filtration (such as filter cloths in filter presses). In the field of chemical engineering, acid and alkali resistant filter cloth can handle corrosive liquids. In the food industry, white non-toxic filter cloths are used for clarifying syrups and fruit juices. In the field of construction, high-strength geotextiles are used for roadbed reinforcement. In addition, protective industrial fabrics (such as flame-retardant fabrics and anti-static fabrics) are also widely used in scenarios like mining and electronic manufacturing. Industry standards have clear requirements for the performance of industrial fabrics, such as air permeability (5-1000L/m²·s), opening rate (50%-90%), and temperature resistance range (-50℃ to 300℃), etc. The selection should be based on specific working conditions. For instance, in high-temperature working conditions, glass fiber filter cloth with a temperature resistance of over 200℃ should be selected, while in strong acid environments, polytetrafluoroethylene (PTFE) material is required.
