Bolian has become a top filter cloth supplier both domestically and overseas, starting from the development of the first patented tower filter press fabric in 1994. Now Bolian currently takes over 90% market share in China for tower press filter cloths, pneuma press cloths, and Roxia filter press cloths.
Adopting advanced global technology to produce high-quality products is the key to Bolian's development. We source our raw materials, weaving looms, and spare parts from advanced global filter cloth manufacturers to produce fine and high-quality products for our customers.
Bolian's well-deserved star filter cloth for sale, which is a high-breaking strength filter cloth with a low elongation rate, was achieved through deep and continuous technology research. Bolian has also developed patented high-density filter cloth with a super smooth surface after thermal setting and calendaring, and non-woven filter cloth that combines the advantages of membrane, non-woven fabrics, and woven fabrics to achieve excellent fabric performance on high filtration accuracy, high breaking strength, stability, etc. This type of filter cloth can be used for lithium extraction and starch. The filtration accuracy can reach up to 5 μm. Bolian tower press filter cloths are widely used in industries such as mining, chemical, metallurgy, food, and environmental protection.
High strength with thermal setting to reach out dimensional stability.
Ultrasonic edge sealing process to avoid fraying edges.
Super smooth surface to make an easier cake release and washing.

Choose the suitable filter cloth based on filter condition.
Elongation control.
Excellent press cloth operation cycle, decrease your total cost of ownership.
Edge coating to prevent leakage.
Ultrasonic cutting with edge sealing.
Glue coating to protect the stitching.
Various types of clipper joint.
Q: How to choose the right product for filtration?
Here are the factors to consider:
Application.
Particle size to be selected.
Filter cloth working temperature.
Filter cloth working pH value.
Type of filter machine.
Q: What is particle size?
Particle size is the diameter of fine particles in the filtrate, determined by the choice of filter cloth.
Q: What is PH value and why consider it?
pH is a measure of acidity, on a scale that ranges from 0 to 14, from strong acid (lower value) through neutral (7) to alkaline (higher value). The PH affects the choice of filter cloth material. For example, PP works across the range but PES is recommended only from PH=3 to PH = 9.
Q: What is fabric? What are the main ways to make it?
Fabrics are flat and soft pieces made up of slender and flexible objects that are crossed, knotted and connected.
Mainly classification:
Weaving: made up of yarns with cross-relationship.
Knitting: made up of yarns with knot-relationship.
Non-woven: made up of yarns and fibers with connection-relationship.
Q: What are the types of yarn?
Yarns consist of staple fibers (e.g. cotton, polyester staple) or filaments(e.g. multifilaments, monofilaments). Spun yarns consist of staple fibers, which are held together by twisting the fibers during spinning.
Monofilament consists of a single filament yarn, a fiber obtained by continuous spinning.
Multifilament yarns consist of slender filaments and a bundle of slender monofilaments. (Bolian multifilaments 0 twist)
Twisted yarns are two or more yarns twisted together into one twisted yarn.
Q: What is industrial filter cloth? What are the main materials?
Industrial filter cloth is a filter media woven from natural fibers and synthetic fibers, belonging to industrial textiles. Main materials are Polypropylene, Polyester, Nylon, Vinylon, Aramid, Full-Cotton, etc. Among them, polypropylene and polyester are more commonly used. Plain, twill, satin, and non-woven needles are main weaving methods.
Q: What are the main applications of industrial filter cloths?
Industrial filter cloth is mainly applied to liquid-solid separation and gas-solid separation. Liquid-solid separation is widely used in mining, chemicals, metallurgy, non-metallic minerals, food, medical and other fields. Gas-solid separation is mainly used in ironworks, steelworks, ferroalloy factories, refractory factories, foundry and other flue gas dust removal systems and flue gas filtration.
Q: What is the definition of breaking strength?
Breaking strength: the maximum force in the process of pulling off the specimen.
Breaking elongation: the breaking elongation is calculated according to the elongation at the maximum force during the stretching process and initial length.
Breaking time: the time corresponding to the breaking elongation. (The stretching speed is constant.)
