Abstract
A woven screen fabric for blocking out undesirable light and glare but admitting air and desirable light comprises 1000 denier high-tenacity polyester core fill yarn coated with a plasticized poly-vinyl chloride plastic coating to a finished diameter of 0.0250.+-.0.0010 inch. The plastic is extruded onto the core yarn and is pigmented and heat, light and UV stabilized and the fill mesh may be 16.+-.1 ends per linear inch. An ECG 150 fiberglass core warp yarn is coated with a poly-vinyl chloride plastisol coating to a finished diameter of 0.0115.+-.0.0010 inch. The plastisol is drip-coated onto the core warp yarn and is pigmented, heat, light and UV stabilized to produce a strong, flexible, weather resistant and abrasion resistant coating. The warp mesh may be 63.+-.2 ends per lineal inch. The fabric may be woven with individual warp yarn members arranged in an over and under relationship with the fill yarn members to provide a group of six individual strand members.
