Belltron® |
Conducting Anti-Static Fiber
I. Fiber Description
Belltron ® anti-static conductive fibers are available in 6 different construction types; various deniers and cut lengths; and three different colors. Static control is offered by blending small amounts of Belltron ® into the primary fiber of choice. Belltron ® also offers superior abrasion resistance due to the impregnated nature of the elements that offer the anti-static properties. While other anti-static fibers are available, most of them are based on coating (which leads to shedding) instead of impregnation technology. Belltron ® is not a laminated fiber, but rather a nylon or polyester fiber containing continuously-embedded anti-static particles which are exposed to the outer surface of the fiber. This novel structure gives Belltron outstanding anti-static properties as well as excellent physical properties. Since Belltron's ® fiber surface is smooth, unlike carbon-coated fibers, almost the same process ability as regular nylon can be expected. Finally, Belltron ® is also available with a polyester matrix polymer (Type B31, BR1) which offers greater acid and heat resistance compared to the nylon Belltron ® versions. Applications include: industrial apparel, dust-free garments, carpets, blankets, curtains, static-free brushes, etc.
