Why Is GORE™ RASTEX® Weaving Fiber different?
GORE™ RASTEX® Weaving Fiber is made from a unique form of expanded PTFE. It has exceptional strength and maintains its dimensional stability better than other synthetic and PTFE fibers.
What happens to supporting scrims during felt manufacturing?
Needle-felting processes can abrade and weaken supporting scrim fibers, and yet it is the supporting scrim that contributes most to the felt's strength. The unique structure of GORE™ RASTEX® Weaving Fiber makes it stronger and able to retain more strength after felting than other PTFE fibers. The result is stronger felts. Manufacturers can even use a looser scrim weave or smaller fiber to attain the same strength compared to other PTFE fibers, especially when GORE™ RASTEX® Weaving Fiber weaving fiber is used.
Identical construction methods and fiber count: 1" wide felt specimens, 3" gauge length.
Why is shrinkage important?
Manufacturers must compensate for fibers that will shrink excessively during processing or in the eventual application. This process is time consuming and unpredictable, resulting in products that do not meet specifications. GORE™ RASTEX® Weaving Fibers shrink less at high temperatures, so filter media are more dimensionally stable, providing higher processing yields and more consistent felts and fabrics. End users will appreciate the dimensional stability because their bags and cartridges will last longer.
Can I use GORE™ RASTEX® Weaving Fiber weaving fibers for liquid filtration applications?
GORE™ RASTEX® Weaving Fiber are available in fine, precise, round cross-section fibers that are ideal for weaving into very fine filtration media and for liquid filtration processing. Contact us for more information.
Do you have any conductive fibers?
Yes, Gore can provide GORE NO-STAT conductive fibers from 1x100 to 1x1018 ohm-cm (please specify in ohm-cm). Contact us for more information.
Where can I buy fabrics and scrims made with RASTEX weaving fibers?
Ask your weaver or contact us for a list of suggested weavers.
NEW! GORE™ RASTEX® Weaving Fiber HT Weaving Fiber - Now there's a fiber that's 45 percent stronger than our conventional RASTEX fiber. Make higher strength scrims and fabrics, or get the same fabric strength using less fiber.
