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

1. 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.

2. The fabric claimed in claim 1 wherein said vinyl coated fiberglass yarn is approximately 0.011 diameter and the vinyl coated polyester yarn is approximately 0.025 diameter.

3. The fabric claimed in claim 2 wherein said mesh is approximately 63×

16 construction.

4. The fabric in claim 1 wherein said vinyl coated fiberglass yarn is in accordance with ASTM D 578-81 specification "Standard Specification for Glass Fiber Yarns."

5. The fabric claimed in claim 4 wherein said vinyl coated fiberglass yarn is made in accordance with ASTM D 3374.80 specification "Standard Specification for Vinyl Coated Glass Yarns".

6. The fabric claimed in claim 4 wherein said polyester yarn is in accordance with Specification ASTM D 3219-79 "Standard Tolerances For Industrial Filaments, Tire Cords, and Tire Cord Fabrics Made From Man-Made Organic-Base Fibers".

7. The fabric claimed in claim 1 wherein said polyester yarn is in accordance with Specification ASTM D 3219-79 "Standard Tolerances for Industrial Filament Yarns, Tire Cords, and Tire Cord Fabrics Made from Man-Made Organic-Base Fibers".

8. The fabric in claim 1 wherein said fiberglass yarn being coated with a polyvinyl chloride plastisol coating, said fiberglass yarn being pigmented and heat, light and UV stabilized.

9. The fabric in claim 1 wherein said polyester yarn is coated with a plasticized polyvinyl chloride plastic coating extruded onto the yarn and pigmented, heat, light and UV stabilized.

10. 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:

12. The fabric claimed in claim 10 wherein said open weave mesh pattern is approximately 63×

16 construction.

11. the strands in the warp direction being vinyl coated fiberglass yarn comprising a fiberglass core yarn which is coated with a vinyl material, said fiberglass yarn being approximately 0.011 diameter and in accordance with ASTM D 3374-80 Specification "Standard Specification for Vinyl Coated Glass Yarns",

the yarns in the direction other than warp being a vinyl coated polyester yarn comprising polyester core yarn which has been coated with a vinyl composition, said polyester yarn being approximately 0.025 diameter and in accordance with Specification ASTM D 3219-79 "Standard Tolerances for Industrial Filament Yarns, Tire Cords, and Tire Cord Fabrics Made From Man-Made Organic Base Fibers".

13. The fabric in claim 11 wherein said fiberglass yarn is in accordance with ASTM D 578-81 Specification "Standard Specification for Glass Fiber Yarns".
