Yarn Structure
| Fabric Type | Structural Features | Filtration Performance | Key Applications |
| Monofilament | Woven from single, smooth, and uniform continuous filaments in both warp and weft. | Clear pores, non-blinding (resistant to clogging), fast drainage. Excellent cake release and long service life with easy regeneration. | Processes with coarser particles requiring rapid discharge and frequent backwashing. |
| Multifilament | Woven from yarns made of multiple fine fibers twisted together (available in staple and filament fibers). | Superior retention of fine particles and extremely high tensile strength. However, it is more prone to clogging and harder to discharge than monofilament. | Fine particle capture and high-pressure filtration conditions. |
