Protection sleeve POLYPURE HOLLOW FIBER SUPPORTS

tubulartextileknitted

PolyPure® is a complete range of braided and knitted reinforcement tubular supports developed for the membrane industry. Once embedded into the filtration membrane fibers, it provides an overall strength up to 500N or even higher. This prevents unexpected filament breakages that causes consequently wastewater being sucked into the filtrate, securing an optimal function of the overall filtration system. Beside the structural strength, it is important that the textile supporting material is not causing geometrical deformations while spinning the membrane fibers. Indeed, if the textile tubular support is not cylindrical or having defects on its surface, it may cause the final membrane fiber being oval or having irregular thickness along the circumference. Additionally, the support shall not have filament breakages that protrudes from the outer surface that can lead to “pinholes” causing filtration defects along the membrane fiber. There are many factors that shall be considered while selecting the correct membrane support material. Inner and outer diameter, material structure, whether braided or knitted, support rigidity, type of filaments and other paraments shall be evaluated. PolyPure® offers a variety of diameters and structures that is suitable theoretically to any tubular membrane production. In terms of diameter the minimal size offered goes down to 1.0mm and a maximum diameter up to 10mm.
