  • the third yarn 131 is plated to selected portions of the exterior surface of the first primary yarn 1 11 to form the enhanced sections 120 on the exterior of the glove 100, as shown in Figures 5 and 6.
  • the first yarn 111 can comprise fiberglass, UHMWPE, stainless-steel wire, flat and/or textured nylon, polyester, and/or a blended UHMWPE/spun polyester
  • the second yarn 121 can comprise spandex.
  • the third yarn 131 comprises elastomeric polyester, bare spandex, and/or rubber yarn.
  • Another embodiment of the invention comprises a cut resistant glove having enhanced slip resistant sections formed on selected areas of the exterior of the glove.
  • the glove can be comprised of a primary yarn and one or more secondary yarns plated to the primary yarn.
  • the primary yarn is a cut resistant yarn defining the body of the glove
  • the secondary yarn is a yarn having slip resistant properties that can be plated to specific areas of the exterior of the primary yarn to form the enhanced slip resistant sections on the exterior of the glove.
  • the primary yarn can comprise fiberglass, UHMWPE, stainless-steel wire, flat and/or textured nylon, polyester, and/or a blended UHMWPE/spun polyester.
  • the secondary yarn can comprise elastomeric polyester, bare spandex, and/or rubber yarn.
  • the primary yarn is comprised of a core comprising one or more strands of fiberglass, UHMWPE, stainless-steel wire, flat and/or textured nylon, polyester, and/or a blended UHMWPE/spun polyester, and one or more cover strands wrapped around the core comprised of UHMWPE, polyester, flat and/or textured nylon, antimicrobial polyester, a blended UHMWPE/spun polyester.
  • the slip resistant yarn comprises a core strand of UHMWPE and one or more covers comprised of slip resistant yarn such as elastomeric polyester, rubber yarn rubber yarn, or thermoplastic polyurethane with a polyester core.
  • the glove provides cut resistance that can protect the user of the glove against accidental cuts that may occur when handling and/or working with sharp objects, such as knives, blades, or broken glass.
  • the enhanced slip resistant sections help the user grip and handle smooth and slippery objects, helping to prevent the user from accidentally dropping the smooth/slippery objects.
  • the glove is ideal for handling glass objects.
  • because the glove is made from knitted breathable fabric it provides ventilation, unlike the dipped gloves often used by glass workers currently. This results in a safer and more comfortable work environment for the user as the glove.
  • compressive refers inclusively to compressive and/or stretching properties.
  • slip resistant refers inclusively to slip resistant and/or enhanced grip or gripping properties. All numerical ranges stated in this application include the lowest and highest value of the range. For example, spandex having a denier of 40 to 1120 includes spandex having a denier of 40 and/or spandex having a denier of 1 120.

Abstract

Un gant de protection peut comprendre un fil primaire résistant aux coupures définissant le corps du gant. La surface intérieure du fil primaire définit la surface intérieure du gant, et la surface extérieure du fil primaire définit la surface extérieure du gant. Des sections améliorées comprennent un fil secondaire et peuvent être formées au niveau de zones particulières du gant. Les sections améliorées ont au moins une caractéristique physique sensiblement améliorée par rapport au reste du gant, telles que des propriétés de compression/étirement améliorées et/ou une préhension/résistance au glissement améliorée par rapport au fil primaire.
