SWM manufactures exceptional high-tenacity polypropylene yarn in a variety of colors and weights. Our vast capabilities in synthetic yarn is to meet our customers’ product specifications and performance targets. Our multifilament synthetic yarn is manufactured in the U.S. and available worldwide. As a leading polypropylene yarn manufacturer, we can produce yarn between 300 and 1600 deniers. For detailed information about our synthetic yarn portfolio and minimum order quantities, please contact our team.
Multifilament denotes a cord or yarn composed of a number of strands or filaments wound together. Tenacity is the measure of strength of a fiber or yarn. It is defined as the ultimate tensile strength of the fiber at the rupture point. Tenacity units are calculated by dividing the breaking force (grams) by the linear density (deniers).
Denier (D) is a unit of weight by which the fineness of silk, rayon or nylon yarn is measured. It is equal to the weight in grams of 9000 meters of the yarn (grams/9,000 m). The low numbers represent the finer sizes of yarn while the higher number, the heavier. Example: if synthetic polypropylene yarn is manufactured to be 300 deniers, it means it weighs 300 grams when 9,000 meters of that yarn are weighted. Thus, if we took 1 meter of that synthetic yarn it would be 0.03 grams.
SWM synthetic fibers are designed and manufactured to provide excellent loft and matrix fill in Turf Reinforcement Mats (TRMs) for permanent erosion control applications. TRMs are permanent Rolled Erosion Control Products (RECPs) composed of non-degradable synthetic fibers, filaments, nets, wire mesh and/or other elements, processed into a permanent, three-dimensional matrix of sufficient thickness.
TRMs are typically used in hydraulic applications, such as high flow ditches and channels, steep slopes, stream banks, and shorelines, where erosive forces may exceed the limits of natural, unreinforced vegetation or in areas where limited vegetation establishment is anticipated. Manufacturers of TRMs use our Conwed™ synthetic fibers with our oriented plastic netting to form superior erosion control products. Our portfolio of synthetic fiber capabilities includes a variety of colors, chemical formulations and recycled material that adapts to the requirements of the final application.
Excellent UV resistance to withstand the ultraviolet radiation exposure the fibers experience in its intended useConwed (formerly known as PROSTRAN) synthetic fibers last longer than competitive products under UV lightIn a comparative product testing, the SWM product showed no loss of strength after 1 year and 50% lower loss of strength after 4 years of UV exposure compared to the closest competitive productHigh-level of quality with consistent length and diameter, providing the manufacturer of the TRM a more uniform and consistent distribution of the synthetic fibers at high production ratesSuperior crimping technology to provide optimum loading and distribution in the TRM matrix
