Abstract
Abstract A woven fabric consisting of warp and filling yarns made from fibers or filaments having a low modulus of elasticity and a large diameter. The fibers can be of any cross-sectional shape but have a moment of inertia of from 400×10 -14 in. 4 to 7.8×10 -9 in. 4 and an elastic modulus of from 2,000 to 80,000 p.s.i. These values correspond to a range of circular diameters of from 0.003 to 0.020 in. The fibers can be loaded with high amounts of fillers, such as pigments, color agents, flame retardants, antistatic agents, antisoiling agents, or antioxidants.
