Definitions

  • the present invention relates to a method for improving the resistance of elastomeric polyester monofilament, especially a co-extruded, two-component monofilament, to degradation from exposure to ultraviolet (UN) light. More particularly, the present invention relates to UV resistant elastomeric monofilament having a sheath and a core which each contain a UV protecting amount of carbon in the range of from about 1.8% up to 3.0% by wt.
  • U.S. Patent No. 4,469,739 describes an oriented woven furniture support material made in part from elastomeric monofilament and in part from natural or synthetic yarn.
  • the elastomer is woven in a first direction and the yarn in a second direction perpendicular to the first direction followed by heat setting of the resulting woven fabric.
  • the thermoplastic elastomer filaments are co-extruded, two-component sheath/core monofilaments in which the elastomer comprising the sheath has a melting point of at least 20°C lower than the core elastomer.
  • a woven fabric e.g., as a seat support material, has been restricted to applications where it would not be exposed to UV light, for example, applications in which the fabric is covered by another layer of material which, in turn, prevents UV light from directly or indirectly contacting the fabric.
  • UN light has been shown to cause a substantial reduction in physical properties of the woven fabric, especially the elastomeric monofilament component of the fabric.
  • the present invention resides in the discovery that the resistance of a two component elastomeric polyester monofilament comprising a sheath and a core to degradation from exposure directly or indirectly to UV light can be substantially improved by incorporating into the elastomeric material of the sheath and the core a UV protecting amount of carbon.
  • the invention is a method for improving the UV resistance of a two component elastomeric monofilament having a core and a sheath by incorporating into said core and into said sheath a UV protecting amount of carbon.
  • the present invention is 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, i.e., sheath, elastomer having a melting point which is at least 20°C lower than the first elastomer, wherein the improvement comprises incorporating into said first elastomer and into said second elastomer a UV protecting amount of carbon, e.g., an amount generally in the range of from about 1.8% to 3.0% by wt. carbon of predetermined particle size.
  • the carbon is incorporated into each elastomer composition by first preparing a concentrate comprising 75% by wt. of that elastomer and 25%) by wt. carbon, and then uniformly blending the carbon/elastomer concentrate into the corresponding base elastomer in a ratio of 10% by wt. concentrate to 90% by wt. base elastomer.
  • concentration of carbon in each of the core and the sheath elastomer components should be in the above-described range, although for best results the concentration of carbon is about 2.5% by wt.
  • the present invention is an improved oriented woven support material, such as, for example, a support material for furniture, comprising 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, and the sheath is an elastomer whose melting point is at least 20°C lower than the melting of the elastomer in the core, and the strands in the second direction comprise a non-elastomeric, natural or synthetic yarn, the improvement comprising incorporating into said sheath and into said core a UV protecting amount of carbon, e.g., an amount generally in the range of from about 1.8% up to 3.0% by weight, and preferably 2.5% by wt. carbon.
  • a UV protecting amount of carbon e.g., an amount generally in the range of from about 1.
  • the resulting elastomeric monofilament has substantially improved resistance to degradation by UV light than when carbon is incorporated into the sheath alone or not at all.
  • thermoplastic elastomer used in the sheath/core monofilament of the invention can be an orientable copolyetherester elastomer, a polyurethane elastomer, or a polyesteramide elastomer, where the melting point of the sheath component is substantially less than the melting point of the core component, i.e., at least about 20°C lower than the melting point of the elastomer in the core.
  • the preferred thermoplastic elastomers for use according to the invention is a copolyetherester elastomer as described in one or more of U.S. Patent Nos.
  • copolyetherester polymers consist essentially of a multiplicity of recurring intralinear long-chain and short-chain ester units connected head-to-tail through ester linkages, their chemical structures being well known to those skilled in the art.
  • the sheath of the monofilament is Hytrel® 4056 polyetherester block copolymer
  • the core of the monofilament is Hytrel® 7246 polyetherester block copolymer (available commercially from E. I. du Pont de Nemours and Company, Wilmington, Delaware).
  • the monofilament is prepared by co-extruding the core and sheath from molten thermoplastic through a die by conventional methods known in the art, such as described in U.S. Patent No. 5,313,909.
  • the monofilament ordinarily consists of about 75% core and about 25% sheath, although exact percentages of elastomer comprising the core and the sheath can vary over a wide range.
  • the carbon used in the invention can be any commercially available carbon black, such as, for example, Vulcan® 9A32 or Elftex 12, having a "fine” to "medium” particle size (available commercially from Cabot Corporation).
  • fine is meant that the particle size of the carbon black is generally in the range of about 19 nm, whereas “medium” particle size means that carbon particles can range in size from “fine” up to about 37-41 nm. Finer particle size carbon tends to offer a higher level of protection from UV degradation, but finer particles can become more difficult to disperse in a polymer and also tend to absorb moisture more quickly than medium or coarse carbon particles. Irrespective of particle size, it is preferred that the carbon black be of a grade which has as low a moisture absorption rate as possible.
  • the carbon black be uniformly distributed within the sheath and core polymer components. It has been found that such a uniform distribution can be achieved by first preparing a carbon/elastomer "concentrate" comprising 25% by wt. carbon and 75% by wt. of the respective base elastomer.
  • the carbon component is intensely mixed and dispersed into the corresponding molten base elastomer in a machine designed for this purpose, such as, for example, a Farrell Continuous Mixer or a Banbury Mixer, and then the concentrate is cut into pellet form using either a melt cutter or a strand cutter.
  • the carbon-containing concentrate is pre-dried to a low moisture level in the range of from 0.005% to
  • the pre-dried carbon-containing concentrate in pellet form and the respective base polymer for the core and the sheath, also in pellet form, are then pre-mixed to insure generally uniform distribution of the carbon-containing concentrate throughout the base polymer pellet mixture.
  • Each base polymer pellet mixture is then extruded in either a single or twin screw extruder where melting and further mixing of the components can occur in the molten state as the melt is metered into a die system where sheath and core components are formed in heated dies designed for this purpose.
  • the molten strands exit the die, are cooled, and then post-oriented in the machine direction to impart strength to the monofilament.
  • the oriented monofilament is then wound onto spools.
  • Monofilament samples produced as described above i.e., the sheath of the monofilament being Hytrel® 4056 polyetherester block copolymer, and the core of the monofilament being Hytrel® 7246 polyetherester block copolymer, were then placed in a Xenon light source standard Weatherometer® (i.e., an "indoor test cycle") and exposed to ultraviolet light to levels of 200 and 400 KJ/m 2 .
  • the cycle was conducted in accordance with SAE J1885. Control samples of each production run were retained and protected from exposure to any UV light. In the table that follows, these control samples are referred to as "0" KJ/m 2 exposure samples.
