Abstract
Weather-resistant fencing products knitted from yarns of synthetic fibers into an open pattern in which from 40 to 80% of the fabric surface is open to the passage of air and particulates. The closed portion resists air and particulates passage causing particulates to be deposited on both the windward and leeward side of the fence. Selection of fence height and degree of openess controls the height and length of the mass of particles accumulated adjacent to the fence. The knit fabric construction is useful as a snow fence.
Claims7
A weather-resistant knitted fabric constructions knitted in a predetermined width from yarns of a tough, elastic, synthetic polymeric material into an open pattern in which from about 40% to about 80% of this product surface is open to the passage of air and particles there through, the closed portion of the pattern providing resistance to the passage of air and particulants there through and causing particulates to deposit and accumulate in the area adjacent the fencing product, the product consisting essentially of:
- a plurality of laid in warp yarns disposed in the machine direction and spaced apart from each other.
- a plurality of weft inserted yarns arranged in bundles of at least two and disposed perpendicular to the machine direction, each bundle of weft inserted yarns spaced apart from the adjacent bundle of bundles,
- a pair of knitting warp yarns for each laid in warp yarn, the knitting warp yarns knitted in the machine direction around the underlying laid in warp and weft yarns, the knitting warp yarns securing the weft inserted yarns to the laid in warp yarns.
- the fabric construction having a relatively thin elastomeric, weather-resistant coating substantially evenly adhered to the surface of and impregnated into each of said strands thereby encapsulating and adhering said strands to each other to rigidify and support the knit product, and to render the product capable of withstanding sustained periods of direct sunlight, the relative thickness of said coating being not greater than the diameter of each of the yarns.
