Definitions

  • the present application pertains to water-resistant and chemical-resistant gloves. More particularly, the present application relates to flexible, sensitive, water-resistant and chemical-resistant gloves made by the use of a dip-line process.
  • Fig. 1 illustrates a glove that can be formed according to the present application.
  • Fig. 2 is a depiction of an exemplary cross-section of a portion of the glove of Figure 1 .
  • the present application relates to a skin-covering, which has improved comfort and also improved resistance to water and chemical permeation.
  • the present application includes a method of forming such a skin-covering.
  • the skin-covering can be a five-fingered glove, but it also can be a mitten having only a thumb or a mitten having any combination of fingers present from zero to five. (See Figure 1 )
  • Such skin-covering is not limited to a glove or mitten, and can comprise an apron, coat, hat, scarf, sock or shoe.
  • the chemical-resistant nature of the glove results from the presence of a multi-layer composition of at least two substantially water-proof layers and a chemical-resistant layer.
  • the substantially water-proof layer is comprised of a mixture of polyurethane and nitrile, although generally it can be made of any material that imparts a substantially water-proof character to the glove, such as polyethylene, nitrile, polyurethane, chloroprene latex, natural latex, butyl latex, fluoric latex, and mixtures thereof.
  • the chemical-resistant layer is comprised of polyvinyl alcohol (PVA), although any material that imparts a chemical-resistant nature to the glove is useful.
  • PVA polyvinyl alcohol
  • the glove also comprises a donnable layer, which lies next to the skin.
  • the PVA layer is sandwiched between two substantially water-proof layers, preferably comprised of a mixture of polyurethane and nitrile.
  • the layer of the polyurethane and nitrile mixture also provides chemical resistance.
  • the PVA layer provides chemical permeation resistance. It is well-known that a broad range of chemicals such as organic solvents, plasticizers, pesticides and detergents cannot readily permeate PVA.
  • U.S. Patent Numbers 4,902,558 and 5,059,477 , and U.S. Application Serial Numbers 12/862,311 ; 61/363,871 ; and 61/393,712 each assigned to Honeywell, which are hereby incorporated by reference, discuss the advantages of having a PVA layer in a chemical-resistant glove. These patents explain that water will tend to swell and plasticize the PVA layer. Therefore, the PVA layer should be protected on both top and bottom from the presence of water.
  • the donnable layer must be substantially water-proof.
  • Suitable donnable layers include those of synthetic fiber, natural fiber, chloroprene latex, natural latex, butyl latex, fluoric latex, polyurethane, polyethylene and mixtures thereof.
  • the donnable layer can be cotton, polyurethane or latex rubber.
  • a substantially water-proof fabric material is also contemplated.
  • One embodiment of the glove (10) comprises multiple layers, including at least one outer layer of a mixture of polyurethane and nitrile (12), enclosing and protecting one adjacent layer of PVA (14), which is directly adjacent to one/two polyurethane and nitrile mixture layers (16-18) for a grand total of three to five layers. (See Figure 2 )
  • Layer 20 is the donnable layer, which when worn is adjacent to the skin of the wearer and is optional. There are no restrictions as to the arrangement of the layers except that the PVA layer preferably is protected from moisture. Also, the thickness of the layers ranges from about 0.1 mm to about 1 mm for both the polyurethane and nitrile mixture layer and the PVA layer.
  • the glove can contain about 1 to 70 weight percent polyvinyl alcohol and 1 to 70 weight percent polyurethane and nitrile mixture.
  • the thickness of the donnable layer is in the range of about 0 mm to about 6 mm thick, or about 0 to 50 weight percent.
  • the polyvinyl alcohol layer (14) is in the range of about 1 to 70 weight percent and the polyurethane and nitrile mixture layer (12) is in the range of about 1 to 70 weight percent, and the polyurethane and nitrile mixture layer (16-18) is in the range of about 1 to 70 weight percent.
  • the present application also contemplates a method of forming a water-resistant and chemical-resistant glove.
  • the method can also encompass the addition of one or more additives wherein the additives comprise an adhesive, a colorant, an anti-microbial agent, a fiber, a fragrance or mixtures thereof.
  • the glove can then be stripped from the former.
  • the paired dipping and removing steps can be independently repeated multiple times to form multiple layers, as desired.
  • a donnable layer i.e., liner
  • the coated former was dipped twice into a polyurethane and nitrile mixture.
  • the dwell time was 0 seconds.
  • Each dipping had a drying time of 4 minutes at 65°C.
  • cotton flock was put on. The glove was dried and stripped from the former.
