Abstract
Window coverings are formed of woven fabrics of acrylic yarns to provide minimal degradation of the window covering due to ultraviolet (UV) radiation and to minimize damage to interior furnishings within a building at which the window coverings are applied. The window coverings are preferably formed of panels of pigmented acrylic yarn having a yarn number of about 24, 2 ply and a weave density of about 29 ends per inch of warp threads and 24 picks per inch of weft threads with about 0.063 inch square openings between the thread rows. UV blocking for A and B wavelength ranges may be on the order of 69 to 78 percent.
