The process of chemical fiber production is complex, involving processes such as spinning, melt processing, waste liquid treatment, and workshop dust removal, all of which have strict requirements for impurity filtration, material separation, and environmental purification. The filter cloth, as the core filtering consumable, thanks to its corrosion resistance, temperature resistance, stable air permeability and liquid permeability, is widely applicable to various working conditions in chemical fiber production and becomes a key material for ensuring stable production, improving product quality, and reducing energy consumption and loss.

In the chemical fiber production site, the filter cloth is not eye-catching, but it runs through multiple processes from raw material treatment to finished fiber spinning. Unlike the main equipment, which is more noticeable, without this layer of filtering medium, impurities, gels and un-melted particles will enter the downstream processes along with the process flow, causing problems such as spinneret blockage, increased breakage rate, and unstable fiber fineness.

The filter materials used in the chemical fiber industry can be roughly divided into two categories. One is industrial filter cloths made of synthetic fibers such as polyester, polypropylene, and nylon, which are commonly used in slurry, wastewater, waste gas and auxiliary processes for solid-liquid and gas-solid separation; the other is metal meshes, sintered felts and melt filter cores in the melt filtration process, located between screw extruders, metering pumps and spinning components, intercepting carbon particles, gels and metal debris before the spinneret. Although they have different forms, the goal is the same: to make the materials entering the downstream processes as clean as possible.

The core value of chemical fiber filter cloths lies in their designability of performance. Synthetic fibers such as polyester, polypropylene and nylon can be adapted to various working conditions through different weaving methods such as plain weave, twill weave or satin weave. In medium-low temperature and strong acid-base working conditions, polypropylene composite filament filter cloths, due to their corrosion resistance to acid and alkali, become a common choice for filter press systems; in the high-temperature flue gas treatment process, modified high-temperature-resistant filter materials can maintain relatively stable filtration efficiency and mechanical strength. This on-demand customization flexibility enables chemical fiber filter cloths not only to serve chemical fiber production itself, but also to provide references for industries such as steel, cement, medicine, food and others that have similar requirements for solid-liquid separation and flue gas purification.
