Definitions

  • the present disclosure relates to protective gloves, in particular elastic, polymeric protective gloves with a textile lining, as well as to a method for their manufacture.
  • a protective glove made of a composite material composed of a textile knitted fabric and a polymer layer has a more powerful adhesion between the textile knit and the polymer layer.
  • German patent disclosure DE 27 59 008 A1 describes a protective glove composed of a textile that has been coated by means of a dip-coating process from a dispersion with polymers such as polyvinyl chloride (PVC) and also describes its manufacturing method and an apparatus conceived for this purpose. Due to the irregular layer thicknesses and the occurrence of diffusion conduits, so-called “pin holes,” a protective glove of this kind has a comparatively poor protective effect. This is also disadvantageous from an economic standpoint because it results in a larger number of rejects. It also requires the use of additives such as coagulation reagents.
  • PVC polyvinyl chloride
  • the object of the present disclosure is to create a polymeric protective glove with a textile lining, which has uniform permeation times across the entire surface of the glove and thus has a reliable protective effect in relation to a variety of chemical compound classes.
  • Another object is to create a glove of this kind that also has a high level of wearing comfort while maintaining flexibility and tactile sensitivity. Another object is to create an efficient method for manufacturing a protective glove of this kind.
  • the present disclosure provides a polymeric protective glove with a textile lining in which the textile lining and at least a first polymer layer are embodied in the form of a layered laminate.
  • the first polymer layer includes a synthetic elastomer, which is embodied in the form of a copolymer with isoprene as a monomer unit, i.e. the elastomer contains isoprene monomer units.
  • copolymers are understood to be polymers with at least two different monomer units.
  • An isoprene monomer unit is understood in particular to be the repeating unit I.
  • Polymers with isoprene monomer units are understood to also include those polymers in which derivatives of isoprene monomer units are present.
  • such polymers are understood to be polymers with isoprene monomer units in which a derivatization has taken place by means of polymer analogous reactions such as halogenation of the polymer.
  • the textile layer of the layered laminate forms the inside of the glove and is understood to be the bottom (innermost) layer. Consequently, the first polymer layer, like optional, subsequent additional polymer layers situated over the said layer, i.e. relative to the glove as it is worn by the user, is situated toward the outside.
  • the layered laminate is constructed so that the textile layer and the first polymer layer are firmly bonded to each other by means of a common boundary layer.
  • the textile layer here can, for process-related reasons, also contain additives or residual amounts of additives such as sizing agents or film-forming substances, in particular polyvinyl alcohol (PVA) or a polysaccharide such as starch.
  • the textile layer and the first polymer layer are held together by a fiber reinforced material layer, i.e. a fiber/synthetic composite.
  • a fiber reinforced material layer i.e. a fiber/synthetic composite.
  • This permits good adhesion of the first polymer layer to the textile lining or textile layer.
  • an adhesive agent in particular a glue.
  • the textile properties of the textile lining are thus largely preserved.
  • the lining and polymer layer form a fiber reinforced material in which the fibers of the textile layer are embedded into a matrix of the polymer of the first polymer layer.
  • the fiber reinforced material is produced when the textile lining or textile layer is dipped into a solution of a synthetic rubber with isoprene monomer units.
  • the polymer solution penetrates into the textile layer and envelops the fibers.
  • the textile layer is thus at least partially penetrated by the polymer layer.
  • An entanglement of the textile fibers with the polymer chains occurs. This increases the contact area between the fibers and the polymer chains and thus also increases the inter- and intramolecular forces of attraction that can be due to interactions such as van-der-Waals forces or adhesion effects.
  • the textile lining is composed of a knitted fabric. It may be desired that, in addition to the first polymer layer, the textile layer or textile lining is elastic.
  • the knitted fabric is preferably a knitted fabric with double loops; an interlock knitted fabric is particularly preferable. This may produce a fiber reinforced material while preserving the textile properties of the lining since the knitted fabric has a sufficient mesh density, which has a positive effect on the degree of impregnation of the textile lining.
  • the knitted fabric of the textile lining contains cellulose-containing fibers. It may be desired that the knitted fabric is composed of cotton or a cotton blend fabric, in particular with a cotton content of greater than 50%. This may be desirable because natural fibers, in particular cellulose-containing fibers, are particularly able to absorb moisture due to their swelling capacity.
  • the cotton fabric has a density of greater than 150 g/m 2 , in particular greater than 250 g/m 2 .
  • the yarn size of the yarn used is preferably 30:1. It has turned out that the penetration of the textile lining can be influenced by means of the density of the knitted fabric in combination with the yarn size.
  • the first polymer layer contains an elastomer with butyl monomer units. It is thus possible to achieve a protective effect in relation to a multitude of compound classes.
  • elastomers with isoprene monomer units such as cross-linked butyl rubbers (IIR), in particular elastomers with butyl monomer units, have a good protective effect in relation to polar solvents and in relation to acids and bases.
  • Low glass temperatures T g result in a very good flexibility, even at low temperatures.
  • elastomers with isoprene units have a low gas permeability, i.e. they are impermeable to a multitude of gases such as hydrogen chloride or ammonia.
  • the first polymer layer contains an elastomer with halogenated butyl monomer units, in particular an elastomer with butyl monomer units that has been halogenated in a polymer analogous reaction. It is particularly preferable for the first polymer layer to contain an elastomer with bromobutyl monomer units; in the context of the present disclosure, bromobutyl monomer units are understood in particular to be the repeating units II, III, and IV.
  • halogenated butyl rubbers are easier to cross-link because of their lower bond energies. This effect is particularly pronounced in rubbers with bromobutyl monomer units.
  • a halogenation of the butyl rubber increases its chemical inertness and thus increases the protective effect of the glove.
  • the first polymer layer is applied to the textile layer by means of a dip-coating process, i.e. a dipping process, in particular a dip-coating process from a solution.
  • a dip-coating process i.e. a dipping process, in particular a dip-coating process from a solution.
  • additives such as coagulation reagents.
  • polymer layers applied by dip-coating processes from solutions have consistent layer properties. It is thereby possible to ensure constant permeation times over the entire glove and thus a reliable protection. It is likewise possible to avoid the occurrence of so-called pin holes, i.e. diffusion conduits, in the polymer layer.
  • the first polymer layer is composed of two polymer sublayers: the first polymer sublayer contains no colorant, the second polymer sublayer contains colorant, and the second polymer sublayer is disposed onto the first polymer sublayer.
  • This embodiment of the first polymer layer may provide uncolored, i.e. light-colored, textile linings that are typically used for protective gloves. Because an uncolored first polymer sublayer is used, the sublayer glistens through the textile lining without influencing the color impression of the lining. On the other hand, users especially prefer protective gloves in which colorants have been added to the polymer layer; hence, the established position of such gloves in the marketplace.
  • At least one second polymer layer of another, different polymer is applied over the first polymer layer.
  • the second polymer layer contains a fluorinated elastomer. Repulsive, i.e. repelling, interactions sharply reduce an adsorption of molecules on the layer surface, thus increasing the resistance to a large number of chemical substance classes. Consequently, the comparatively high grease, oil, and fuel permeability of the first polymer layer's elastomer with isoprene monomer units can be compensated for through combination with the second polymer layer.
  • the second polymer layer contains an elastomer with 1,1-difluoroethylene monomer units.
  • Fluoroelastomers with 1,1-difluoroethylene monomer units are inert in relation to many chemicals, oils, and fuels and are heat resistant.
  • the high tear resistance of up to 20 MPa of fluororubbers with 1,1-difluoroethylene monomer units also results in a high mechanical resistance of the polymer composite material.
  • the second polymer layer contains a copolymer with the monomers 1,1-difluoroethylene and hexafluoropropene.
  • the second polymer layer contains an elastomer with acrylonitrile monomer units such as a cross-linked nitrile rubber (NBR).
  • NBR cross-linked nitrile rubber
  • the protective glove has a first polymer layer with a thickness of 0.05 mm to 0.5 mm and/or a second polymer layer with a thickness of 0.05 mm to 0.15 mm. This has a good effect on permeation times, flexibility, and wearing comfort.
  • the manufacturing method is composed of at least the following steps:
  • step a a textile lining is placed onto a glove form.
  • an anti-friction agent may be used, such as a silicone oil, which is applied to the glove form in advance.
  • step b) a solution of a film-forming polymer is applied to the textile lining that has been placed onto the glove form.
  • step c) a glove form is dipped into a first solution of a synthetic, first rubber.
  • the temperature T 1 during the dip-coating procedure is lower than the cross-linking temperature of the first rubber.
  • step d) the glove form is removed from the first solution
  • step d) the first solution
  • step d) the first solution
  • step d) the drying time
  • step f) the first polymer layer is vulcanized by autoclaving the protective glove.
  • step g the protective glove is removed from the form.
  • step c) the glove form is dipped into a first solution of a butyl rubber, preferably a first solution of a halogenated butyl rubber, and particularly preferably a first solution of a rubber with bromobutyl monomer units.
  • the glove form is dipped into a second solution of a second, other synthetic rubber. After a predefined dipping time t 2 , the glove form is removed from the solution and dried.
  • the first and second polymer layers are jointly vulcanized in step f).
  • the second solution may contain a rubber with the monomers 1,1-difluoroethylene and/or hexafluoropropene. This has a positive effect on the properties of the glove, for example on the permeation times for a multitude of chemical compound classes.
  • polar polymers with hydroxyl groups are used as film-forming polymers.
  • these polymers are water-soluble.
  • a PVA solution and/or a polysaccharide-containing solution such as a starch-containing solution are used as a solution of a film-forming polymer.
  • a plasticiser, in particular glycerin is added to the film-forming polymer solution.
  • a spraying or a single or multiple brushing or dabbing of the textile lining with a cloth impregnated with the solution of the film-forming polymer can prevent a complete penetration with the rubber solution. It is thus possible to prevent a complete penetration of the textile lining.
  • This effect is particularly pronounced with cellulose-containing textiles.
  • Cellulose-containing fibers such as cotton fibers swell significantly in the presence of moisture and absorb the moisture. The application of the film-forming polymer thus makes it possible to optimally pre-treat these fibers for the subsequent dip-coating procedure.
  • the textile lining before being dipped into the first solution of a rubber with isoprene units, the textile lining is brushed with the PVA solution until the amount of application of PVA onto the lining totals 0.15 to 3 g, preferably 0.3 to 1.8 g, particularly preferably 0.6 to 0.9 g. It is thus possible to influence the degree to which the rubber impregnates the textile lining.
  • the textile lining is sprayed with a solution containing a polysaccharide such as starch.
  • This solution preferably functions as a sizing agent.
  • a polysaccharide, in particular starch as a film-forming polymer has the advantage that the protective glove does not stick very powerfully to the glove form. As a result, after production, the glove can surprisingly be removed from the glove form even without turning it inside out, which significantly improves the production process.
  • the viscosity of the first rubber solution is from 100 to 200 s (determined with a 6 mm Ford beaker). This is good because a rubber solution with a high viscosity, due to its flow behavior, penetrates more slowly into the textile lining than corresponding solutions with lower viscosities. Consequently, the selection of the viscosity of the first rubber solution constitutes a further parameter which, in combination with the film-forming polymer, can be used to influence the degree of penetration.
  • the textile lining is dipped into two different solutions of the same first synthetic rubber, which differ in terms of their viscosities.
  • the textile lining is dipped according to process steps c) and d) into a solution of the first synthetic rubber with a high viscosity.
  • This produces a first polymer sublayer, which does not completely penetrate the textile layer and seals the surface of the textile lining on the outside.
  • the dipping takes place in a second solution of the first synthetic rubber with a lower viscosity, thus contributing to a further build-up of the first polymer layer. This is good for process-related reasons since rubber solutions with comparatively low viscosities are easier to work with when dip-coating from a solution.
  • the glove form is preferably dipped partially at least once and then is dipped all the way.
  • the partial dipping is also desired in terms of the degree of penetration of the textile layer.
  • Each dip-coating procedure of the glove form into the same rubber solution produces another layer of the rubber, which is referred to as a dipped polymer sublayer.
  • a dipped polymer sublayer After a dipped polymer sublayer has been deposited in the first partial dipping procedure, which seals the textile lining up to approximately the wrist, then a full dipping can occur, i.e. with a higher hydrostatic pressure at the fingers, without this disadvantageously affecting the impregnation depth of the textile lining.
  • a preferred embodiment of the present disclosure provides a method in which the polymer layers are dipped as often and for as long as necessary until the first polymer layer has reached a thickness of 0.05 to 0.5 mm and/or the second polymer layer has reached a thickness of 0.05 to 0.2 mm.
  • the vulcanization of the first polymer layer preferably occurs by means of autoclaving at a pressure of 3 to 5 bar and/or at a temperature of 60 to 170° C., in particular at a temperature of 90 to 150° C.
  • a cross-linking of rubbers into elastomers increases their mechanical resistance significantly.
  • the cross-linking reduces the permeation rates within the cross-linked polymer layers.
  • the removed protective gloves may be washed with water to which tensides have preferably been added. Residues of PVA and/or starch that are not enveloped by the first polymer layer can thus be at least partially removed from the textile lining.
  • one advantage in the use of starch as a film-forming polymer lies in the fact that it is possible to dispense with the use of rinsing agents when removing the protective glove from the glove form.
  • the starch can remain in the textile lining without a significant, negative impact on the wearing comfort, so that it is possible to dispense with an additional step of washing out the finished protective glove, thus making it possible to increase productivity.
