Abstract
An extruded oriented thermo-plastic polymeric element for industrial textiles, and textiles comprising polymeric elements. The polymeric elements are constructed of a material selected from yarn material, fiber material and film, and comprise a thermoplastic polymer, and at least one dry lubricant, selected from molybdenum disulphide, tungsten disulphide, boron nitride, and a soft metal, the dry lubricant comprising particulate matter having an average particle size between about 0.05μ and about 100μ, and present in the polymeric element in an amount from between about 0.1% and about 10% parts by weight, based on a total weight of the polymeric element. The polymeric elements can be used as yarns in woven and non woven textiles, and as seaming elements. The polymeric elements provide increased abrasion resistance in industrial textiles, and reduced co-efficient of friction.
