In the world of industrial solid-liquid separation, filter cloth is far more than just an ordinary fabric—it is the key material that determines filtration efficiency and equipment stability. At Bolian, every meter of high-quality filter cloth is born from a relentless pursuit of precision craftsmanship.
The story of filter cloth begins with yarn. Twisting is the starting point of the entire weaving process. Through precise twisting, loose fibers are transformed into compact and resilient yarns. Bolian applies advanced tension balance control technology, enhancing yarn cohesion by 20%. This significantly improves the abrasion resistance and tensile strength of the filter cloth, laying a solid foundation for subsequent weaving.
Bolian adopts sectional precision warping technology to align thousands of warp yarns uniformly. With a dynamic tension control system, the yarn tension deviation is maintained within 0.5%, and warp beam formation error is strictly limited to ±1mm. Such high-precision control ensures smooth weaving and provides filter cloth with a stable and uniform structure.
Weaving is the critical stage where filter cloth truly takes shape. Bolian’s production workshop is equipped with multiple imported rapier looms, combining European weaving techniques with intelligent control systems. Warp and weft yarns are precisely arranged at micron-level accuracy. By flexibly switching between plain, twill, and satin weaves, Bolian can develop customized filter fabrics to meet diverse industrial requirements. With an annual production capacity of 6 million square meters, Bolian ensures stable supply not only for domestic clients but also for global markets.
At Bolian, the journey of filter cloth continues beyond weaving. The finishing stage is where precision meets craftsmanship. Bolian’s self-developed hot roller setting process eliminates stress through accurate temperature control, ensuring dimensional stability. Calendering gives the cloth a smooth surface, reducing medium resistance and improving filtration efficiency.
Unique edge sealing and joint treatment techniques enhance durability and sealing performance, significantly extending the filter cloth’s service life.
Finally, every roll undergoes strict quality control, intelligent warehousing, and full-process logistics tracking to guarantee safe delivery to customers worldwide.
Bolian adheres to the principle of “Source Control, Precision Manufacturing,” applying advanced processes and strict standards to empower industrial filtration. Every piece of filter cloth is not only a product of craftsmanship but also a promise of quality and reliability to users around the world.
