In industrial production and daily life, filtration is a very important operation, and chemical fiber filter cloth as a filter material, plays a key role. Chemical fiber filter cloth is a filter fabric made of chemical fibers as raw materials, these chemical fibers include polyester fiber (polyester), polypropylene fiber (polypropylene), polyamide fiber (nylon), etc., through the textile process to interweave fibers into cloth materials with specific filtration properties.

Filter cloths for the chemical fiber industry

High filtration accuracy: It can effectively intercept solid particles of different sizes, suspended solids and other impurities to meet the requirements of various industrial production and environmental protection fields for filtration accuracy, such as in food and beverage production, can filter out small impurities to ensure the purity of the product.

Good chemical stability: most chemical fiber filter cloth has a certain tolerance to common acids, alkalis and other chemicals, and can work stably in different chemical environments, such as playing an important role in the filtration of acid and alkali solutions in chemical production.

Excellent physical properties: with high strength and wear resistance, can withstand a certain amount of pressure and friction, in the process of industrial filtration is not easy to damage, extend the service life; Some chemical fiber filter cloth also has good high temperature or low temperature resistance, adapt to the filtration needs under different temperature conditions.

Controllable permeability: By adjusting the type of fiber, fabric structure, etc., the permeability of the filter cloth can be controlled, making it suitable for different scenarios such as gas filtration and liquid filtration.

Filter cloth classification

Classification by fiber type

Polyester filter cloth: made of polyester fiber, high strength, nearly 1 times higher than cotton, 3 times higher than wool, fabric strong and durable; Good heat resistance, can be used at 70-170 ℃, is the synthetic fiber heat resistance and thermal stability is better; The elasticity is close to wool, the wrinkle resistance is more than other fibers, the fabric is not easy to wrinkle, and the shape preservation is good; The wear resistance is second only to polyamide fiber, ranking second in synthetic fiber; Low water absorption and moisture recovery, good insulation performance, but due to low water absorption, friction generated static electricity, dyeing performance is poor.

Polypropylene filter cloth: polypropylene fiber as raw material, with the characteristics of light weight, density is only 0.9-0.91 g/cm; Strong chemical stability, excellent acid and alkali resistance; Little hygroscopicity, almost no hygroscopicity; Good wear resistance, can withstand friction to a certain extent.

Nylon filter cloth: made of polyamide fiber, wear resistance ranks first in natural fiber and chemical fiber fabric, high strength, good resilience, can withstand repeated stretching and bending; Moisture absorption in synthetic fibers is better, more comfortable to wear, but the heat resistance and light resistance is poor.

Classified by weaving method

Woven filter cloth: through the warp and weft yarn interwoven, the cloth surface is flat, the structure is tight, the filtration accuracy is relatively high, often used in the filtration accuracy requirements of the industrial filtration scene, such as chemical, pharmaceutical and other industries solid-liquid separation.

Knitted filter cloth: woven by the knitting process, with good elasticity and flexibility, in some need to filter materials to adapt to complex shapes or have a certain flexibility applications, such as filtering some special shape of the liquid in the container.

Nonwoven filter cloth (non-woven fabric) : not through the traditional textile process, but through melt-blown, hot melt, spunbond, needling, spunling and other processes through multiple processes. High quality stability, large dust capacity, good moisture resistance, long service life, widely used in coarse effect, medium effect plate, bag filter, composite non-woven fabric can also be used in high efficiency, and even sub-high efficiency filter.
