Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
244 words
A woven shade screening fabric comprising a plurality of individual, spaced strands in parallel relationship in one direction of either the warp or fill of a woven fabric and comprising individual strands in substantially uniform pattern, a plurality of groups of strands closely associated in side-by-side relationship in the other direction of the fabric of the warp and fill from that of the preceding described uniform strands, said groups of strands being equally spaced to provide an open weave mesh pattern therebetween for the purposes of admitting some light and air while blocking some of the glare and sunlight, and the strands in each of said groups being arranged with one strand over and the next strand under in alternating interlocking relationship at the point of crossing each of the respective strands in the other direction whereby in each point of intersection some of said strands are over and some of said strands are under and the next successive crossing of groups of strands alternate from the preceding one, each of the next successive strands alternating from over to under at each intersection and then alternating from under to over at the next intersection, the improvement comprising: the strands in the warp direction being vinyl coated fiberglass yarns comprising a fiberglass core yarn which is coated with a vinyl material, the yarns in the other direction being a vinyl coated polyester yarn comprising polyester core yarn which has been coated with a vinyl composition.
