In industrial production, filtration and separation technology is a core process for ensuring product quality and improving efficiency. Whether it is liquid purification in chemicals, solid-liquid separation in the food industry, or impurity removal in the new energy sector, the performance of industrial filter cloth directly determines the stability and reliability of the entire filtration system.
As essential consumables in this field, the continuous innovation of materials—such as polyester, acid-alkali resistant, nylon, and PP (polypropylene) filter cloths—is driving the industry toward greater efficiency and smarter operations. This article provides an in-depth analysis of the technical characteristics and applications of industrial filter fabrics, highlighting the technical expertise of a leading supplier: CIRCOR (Jiangsu Sheke Technology Co., Ltd.).
The selection of industrial filter cloth must be customized based on the chemical properties of the filtration media, temperature range, and required filtration precision. Currently, the mainstream types on the market include Polyester, Acid-Alkali Resistant, Nylon, and PP filter cloths. Their technical characteristics and applications are as follows:
Made from polyester fibers, this fabric is characterized by high-temperature resistance (up to 150°C) and high tensile strength (breaking strength ≥400N/5cm). It is ideal for routine filtration in the chemical, food, and pharmaceutical industries. With specialized surface treatments, it achieves a filtration precision of 0.5–200 microns, meeting needs from coarse to fine filtration. In chemical production, polyester cloth is often used for primary filtration of acidic or basic liquids, offering a service life more than twice that of traditional materials due to its corrosion resistance.
Designed for strong acids, bases, or highly corrosive media, these cloths use modified polypropylene or PTFE coating technology to reach new levels of chemical stability. Data shows these fabrics can operate continuously for over 500 hours in solutions with a pH range of 1–14, with a filtration efficiency decay of less than 5%. In new energy battery production, they are widely used for electrolyte purification, where their corrosion resistance prevents impurities caused by cloth damage, ensuring battery consistency and safety.
Using Nylon 6 or Nylon 66 as the base material, these cloths feature a uniform pore structure created through a monofilament weaving process. With precision reaching the 0.1-micron level, they are suited for sectors with extreme cleanliness requirements, such as semiconductors and biomedicine. For example, in chip manufacturing, nylon filter cloth is used for terminal filtration in ultrapure water systems. Its low protein-binding properties reduce microbial contamination risks, keeping water conductivity stable below 0.1μS/cm.
PP (Polypropylene) filter cloth is made from lightweight fibers with a density of only 0.91g/cm³. It offers strong chemical resistance at a cost over 30% lower than other materials. In environmental water treatment, PP cloth is the standard for sludge dewatering; its hydrophobic nature accelerates water discharge, reducing sludge moisture content from 95% to below 60%, significantly lowering disposal costs. Additionally, its excellent regeneration capability allows it to recover over 80% of its filtration capacity after backwashing, extending its lifespan by 1.5 times compared to traditional media.
In the field of industrial filtration, CIRCOR (Jiangsu Sheke Technology Co., Ltd.) has become a highly recognized supplier through deep technical expertise and strong R&D capabilities.
