Abstract
UV resistant elastomeric monofilament having a sheath and a core which each contain in the range of about 1.8 % up to about 3.0 % by wt. carbon.
Claims
1. A method for improving the UN resistance of a two component elastomeric monofilament having a core and a sheath, said core consisting essentially of a first polyester elastomer and said sheath consisting essentially of a second polyester elastomer having a melting point which is at least 20°C lower than the first elastomer, said core and sheath elastomers being selected from the group consisting of copolyetheresters, polyurethanes, and polyesteramides, which comprises incorporating into said core and into said sheath a UN protecting amount of carbon.
2. The method of claim 1 in which the carbon is incorporated into each of said core and said sheath elastomer components by first forming a carbon/elastomer concentrate of each component comprising 75% by wt. of each of said elastomer and 25% by wt. carbon, drying the concentrate to a low moisture level in the range of from 0.005% to 0.02% by weight moisture, and then uniformly blending the resulting said carbon/elastomer concentrate into the corresponding base elastomer in a ratio of 10% by wt. concentrate to 90% by wt. base elastomer whereby the resulting concentration of carbon in each of the said core and said sheath elastomer components is in the range of from about 1.8% up to about 3.0% by wt. carbon.
3. The method of claim 2 in which the carbon /elastomer concentrate is first uniformly blended into each of the corresponding base polymers, and then the resulting base polymer/concentrate blends are dried until the moisture level of the concentrate is in the range of from 0.005% to 0.02% by weight.
4. An improved two-component elastomeric monofilament having a core consisting essentially of a first polyester elastomer and a sheath consisting essentially of a second polyester elastomer, said second elastomer having a melting point which is at least 20°C lower than the first elastomer, said core and said sheath elastomers being selected from the group consisting of copolyetheresters, polyurethanes, and polyesteramides, wherein the improvement comprises incorporating into said first elastomer and into said second elastomer a UV protecting amount of carbon.
5. The monofilament of claim 4 in which the carbon comprises particles having a size in the range of from about 19 nm to about 45 nm.
11
6. An improved oriented woven support material which is a fabric having a configuration which comprises crossed strands in a first direction and in a second direction perpendicular to the first direction, wherein the strands in the first direction comprise oriented thermoplastic elastomer monofilament of a sheath/core configuration selected from the group consisting of copolyetheresters, polyurethanes, and polyesteramides, said sheath being an elastomer having a melting point which is at least 20°C lower than the melting point of the elastomer comprising said core, and the strands in the second direction comprise a non- elastomeric, natural or synthetic yarn, the improvement comprising incorporating into said first elastomer and into said second elastomer a UN protecting amount of carbon.
7. The fabric of claim 6 wherein the strands in the second direction comprise oriented thermoplastic elastomer monofilament of a sheath/core configuration selected from the group consisting of copolyetheresters, polyurethanes, and polyesteramides, said sheath being an elastomer having a melting point which is at least 20°C lower than the melting point of the elastomer comprising said core and the UN protecting amount of carbon is uniformly distributed within the sheath and within the core at a concentration in the range of about 1.8% to 3.0% by weight.
