Our fabrics are made with various combinations of vinyl coated yarns in diameters ranging from .010 to .025, Olefin yarns with 300 or 650 deniers, and Acrylic yarns from 8/1cc to 18/2cc. Our fabrics can be woven in widths from 48" to 96", and slit to as small as 17" wide.
The results below are representative of real data from single test samples. Presently no specification is incorporated.
