Description

  Elastomeric gloves such as surgical and test gloves are customarily formed from natural or synthetic elastomers to provide a good combination of elasticity and strength. However, due to the close fit to the hand, elastomeric gloves are often difficult to wear. In order to solve this problem, conventionally, a powder lubricant has been applied to the inner surface of the glove in order to reduce friction between the skin and the elastomer. As an example to easily slip over the user's hand, epichlorohydrin treated and cross-linked corn starch was a common powder applied to the inside of elastomeric gloves during manufacture.

  Unfortunately, the use of powder lubricants has drawbacks in certain situations, such as with surgical gloves. Specifically, if a portion of the powder enters the surgical environment from inside the glove, for example if the glove is torn during the surgery, the powder will enter the surgical wound and further complications to the patient May cause. Powders can also carry pathogens and / or cause allergic reactions in patients.

  As a result, a variety of other techniques have been developed to assist in wearing elastomeric gloves. For example, the surface of natural rubber latex gloves has been chlorinated in order to reduce friction between the wearer contact surface and the user's skin when worn. In addition, other techniques have also been developed to increase the lubricity of the inner surface of the glove. One such technique is described in US Patent No. 5,792,531 to Littleton et al. For example, as one example, Littleton et al., U.S. Pat. No. 5,749,831, formed a S-EB-S glove doning layer from a S-I-S midblock unsaturated block copolymer, chlorinated the formed glove in a washing machine, It shows the application of a lubricant comprising cetylpyridinium chloride and a silicone emulsion (DC365 from Dow Corning) to the wearer contact surface of the glove.

  Although chlorination techniques as described above have provided significant improvements to the doning layer of many elastomeric gloves, they can also adversely affect other properties of the glove. For example, when chlorinated, the internal and external surfaces of the glove are simultaneously chlorinated in the washing machine, so that the external gripping surface made of natural rubber latex is imparted with an undesirable sliding sensation. As a result, a user wearing such a glove will experience difficulty grasping and / or handling the object. This can be a particularly serious problem for surgical gloves designed for use by physicians who are commonly required to grasp and handle surgical tools.

  Thus, there is a current need for an elastomeric glove that can achieve good gripping properties even when chlorinated.

  According to one embodiment of the present invention, an elastomeric glove is disclosed as defining a wearer contact surface and a gripping surface. The glove includes a substrate body that includes a layer formed from an elastomeric material that can be halogenated (eg, chlorinated), the substrate body having an inner surface and an outer surface. In some embodiments, the elastomeric material of the substrate body is a styrene-ethylene-butylene-styrene block copolymer, styrene-isoprene-styrene block copolymer, styrene-butadiene-styrene block copolymer, styrene-isoprene block copolymer, styrene-butadiene. Selected from the group consisting of block copolymers, natural rubber latex, nitrile rubber, isoprene rubber, chloroprene rubber, polyvinyl chloride, silicon rubber, and combinations thereof.

  The glove further includes an outer layer that overlaps the outer surface of the substrate body and forms the gripping surface of the glove, the outer layer being formed from a silicone emulsion. As described in more detail below, the silicone emulsion can maintain some degree of tackiness on the gripping surface of the glove even after the glove is exposed to the halogen-containing compound. In some embodiments, the silicone emulsion is at least one selected from the group consisting of amino, carboxyl, hydroxyl, ether, polyether, aldehyde, ketone, amide, ester, thiol group, and combinations thereof. Includes polysiloxanes with functional groups. Further, the silicone emulsion can have from about 0.1% to about 10% by weight solids component. In another embodiment, the silicone emulsion can have a solids component of about 0.25% to about 5% by weight. In yet another embodiment, the silicone emulsion can have from about 0.3 wt% to about 1.0 wt% solids component.

  In addition to the layers described above, the elastomeric glove can also include other additional layers. For example, in one embodiment, the elastomeric glove further includes a doning layer overlying the outer surface of the substrate body. The doning layer facilitates the wearing of gloves on the wearer's hand. In some embodiments, the doning layer comprises a halogenated (eg, chlorinated) doning polymer. The glove also includes a lubricant that coats the doning layer. When utilized, the lubricant can further facilitate wearing when the glove is wet.

  According to another embodiment of the present invention, a method for enhancing the gripping characteristics of an elastomeric glove is shown. The method includes a substrate body having a layer formed from an elastomeric material, the substrate having an inner surface and an outer surface. The glove further includes a doning layer overlying the inner surface of the substrate body. The method further includes applying a silicone emulsion to the substrate body such that the emulsion covers the outer surface of the substrate body. After this, the elastomeric glove is exposed to a halogen-containing compound such as a chloride-containing composite. The silicone emulsion improves the gripping properties by preventing halogenation of the outer surface of the substrate body.

  Other features and aspects of the present invention are described in detail below.

The complete and operable disclosure of the invention, including the best mode of the invention, is presented by the description with reference to the accompanying drawings as directed to those skilled in the art.
The repeated use of reference signs in the description and the drawings represents the same or similar features or elements of the present invention.

  Details are provided below for various embodiments of the invention, one or more examples of which are set forth below. Each example is provided by way of explanation, not limitation, of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. For example, features illustrated or described as part of one embodiment can be utilized in another embodiment to yield yet another embodiment. Thus, the present invention is intended to include modifications and changes.

  In general, the present invention is directed to an elastomeric glove having an outer layer containing a silicone emulsion. For example, in one embodiment, the glove includes a natural rubber latex substrate body, a doning layer that can be chlorinated, and an outer layer formed from a silicone emulsion. By applying a silicone emulsion to the outer layer of the glove, it can happen that the normal slipperiness due to chlorination can be counteracted and the gripping characteristics of the formed elastomeric glove can be improved. It's been found. In particular, silicone emulsions can block the ability of halogen atoms to adhere to the elastomeric material of the substrate, thereby limiting the degree of slipperiness normally imparted during chlorination. Are known.

  For example, referring to FIGS. 1-2, one embodiment of an elastomeric glove 20 is depicted as being positioned on a user 22 hand. The glove 20 includes a base body 24 having the basic shape of a glove. The substrate body 24 can generally be formed from any natural and / or synthetic elastomeric material known to those skilled in the art. For example, some examples of suitable elastomeric materials include, but are not limited to, S-EB-S (styrene-ethylene-butylene-styrene) block copolymers, S-I-S (styrene-isoprene- Styrene) block copolymer, SBS (styrene-butadiene-styrene) block copolymer, SI (styrene-isoprene) block copolymer, SB (styrene-butadiene) block copolymer, natural rubber latex, nitrile rubber, isoprene rubber Chloroprene rubber, polyvinyl chloride, silicon rubber, and combinations thereof. Other suitable elastomeric materials that can be used to form the substrate body 24 are Buddenhagen et al. US Pat. No. 5,112,900, Buddenhagen et al. US Pat. No. 5,407,715, Plumhottam et al. U.S. Pat. No. 5,900,452, Plamshottam et al. U.S. Pat. No. 6,288,159, Weikel et al. U.S. Pat. No. 6,306,514, all in all, Incorporated herein by reference.

  In one embodiment, the substrate body 24 is formed from natural rubber latex. In order to form the substrate body 24 from natural rubber latex, the former is first immersed in a coagulant bath, which facilitates later peeling of the glove from the former. The coagulant bath can contain compounds known to those skilled in the art, such as calcium carbonate and calcium nitrate. The coagulant-coated former is then dried and then immersed in one or more latex baths. The formed latex layer is then typically immersed in water to extract a large percentage of water soluble impurities present in the latex and coagulant. The coated former is then dried to cure (ie, crosslink) the rubber. It should be understood that the conditions, processes, and materials used to form the natural rubber gloves are well known to those skilled in the art and are not critical to the practice of the present invention.

  Regardless of the particular material used to form the substrate body 24, the glove 20 also includes an outer layer 36 that covers the outer surface of the substrate body 24 during use and forms the gripping surface 21 of the glove 20. . The outer layer 36 includes a silicone emulsion that provides enhanced adhesion to the gripping surface 21. The term “silicon” as used herein generally refers to a broad family of synthetic polymers having a repetitive silicon-oxygen backbone, including but not limited to amino, carboxyl, hydroxyl, ether , Polydimethylsiloxanes and polysiloxanes having hydrogen bonding functional groups selected from the group consisting of: polyethers, aldehydes, ketones, amides, esters, and thiol groups. Silicone emulsions are typically one or more silicon elastomers that can interfere with the adhesion of halogen atoms to the elastomeric material used to form the substrate body 24 during halogenation. including. For example, natural rubber latex is a colloidal suspension of polyisoprene, which generally has the following structure.

  Typically, when halogenating, halogen atoms (eg, chlorine, bromine, and the like) react with polyisoprene to reduce latex tack. However, according to the present invention, the silicon emulsion applied to the outer layer 36 interferes with the reaction between polyisoprene and halogen atoms, thereby preventing the slipperiness normally imparted to the outer layer 36. Has been shown to be. Specifically, in some instances, relatively hydrophobic silicon is believed to repel the often utilized aqueous-based halogenated solutions, thus preventing halogenation of the gripping surface 21. In another example, the silicon contains a functional group that adheres to a reactive site that would form an adhesion with a halogen atom during halogenation if the silicon does not contain a functional group. It is thought to do. By reducing the degree of halogen atom adhesion, the gripping characteristics of the formed glove 20 are significantly improved.

In general, any silicon that can enhance the grip characteristics of the glove 20 can be used in the silicone emulsion. In some embodiments, polydimethylsiloxane and / or modified polysiloxane can be used as the silicon component of the emulsions of the present invention.

Phenyl modified polysiloxanes having a relatively low phenyl content (less than about 50 mole percent) are particularly effective in the present invention. For example, the phenyl modified polysiloxane can be a diphenyl modified silicon, such as diphenyl modified dimethyl polysiloxane. In some embodiments, the phenyl-modified polysiloxane is in some embodiments in an amount of about 0.5 mol% to about 50 mol%, in some embodiments less than about 25 mol%. Contains phenyl units in an amount less than about 15 mole percent. In one particular embodiment, diphenylsiloxane modified dimethylpolysiloxanes containing less than about 5 mole percent, specifically less than about 2 mole percent of diphenylsiloxane units can be used. Diphenylsiloxane modified dimethylpolysiloxane can be combined with dimethylsiloxane by a diphenylsiloxane reaction.

  As noted above, fluoro-modified polysiloxanes can also be used in the present invention. For example, one suitable fluoro-modified polysiloxane that can be used is polysiloxane modified trifluoropropyl, such as dimethylpolysiloxane modified trifluoropropylsiloxane. Trifluoropropylsiloxane-modified dimethylpolysiloxane can be synthesized by reacting methyl 3, 3, 3 trifluoropropylsiloxane and bonding with dimethylsiloxane. The fluoro-modified silicon can contain from about 5 mol% to about 95 mol% fluoro groups, such as trifluoropropylsiloxane units. In another embodiment, the fluoro-modified silicon can include from about 40 mole percent to about 60 mole percent fluoro groups. In one particular embodiment, a trifluoropropylsiloxane modified dimethylpolysiloxane containing 50 mole% trifluoropropylsiloxane units can be used.

  The specific polysiloxanes mentioned above are meant to include heteropolymers or copolymers formed from the polymerization or copolymerization of dimethylsiloxane rings and dimethylsiloxane or trifluoropropylsiloxane rings with appropriate end capping units. To do. Thus, for example, the terms “diphenyl-modified dimethylpolysiloxane” and “diphenylpolysiloxane and dimethylpolysiloxane” can be used interchangeably. Further examples of other suitable polysiloxanes are believed to be described in Chen et al. US Pat. No. 5,742,943 and Weikel et al. US Pat. No. 6,306,514, all in their entirety.

  In addition, the doning layer 30 can be covered with the lubricating layer 32 to assist wearing the article even when the user's body is wet or dry. Lubricating layer 32 can also include a cationic surfactant (eg, cetylpyridinium chloride), an anionic surfactant (eg, sodium lauryl sulfate), a nonionic surfactant, and the like. For example, in one embodiment, the lubrication layer 32 is manufactured by Goldschmidt Chemical Corp., Dublin, Ohio. 4 element ammonium compounds, such as those available under the trademark Verisot BTMS, and silicone emulsions such as those obtained under the trademark AF-60 from General Electric Silicone. Verisoft BTMS contains behenyl trimethyl sulfate and cetyl alcohol, and AF-60 contains polydimethylsiloxane, acetylaldehyde, and a small proportion of emulsifier. In another embodiment, the lubrication layer 32 includes a silicon emulsion that can be the same as or different from the silicon emulsion used to form the outer layer 36. For example, in some embodiments, the lubrication layer 32 can include DC365 (Dow Corning) or SM2140 (GE Silicones).

  The elastomeric articles formed according to the present invention can be formed using a variety of methods generally known to those skilled in the art. In fact, any method capable of forming an elastomeric article can be utilized in the present invention. For example, elastomeric article composition techniques can utilize dipping, spraying, halogenation, drying, curing, and other techniques known to those skilled in the art. In this regard, with reference to FIG. 3, one embodiment of a glove dip molding method is described in more detail. Although a batch process is described herein, a semi-batch process and a continuous process can also be utilized in the present invention.

  Initially, a well-known former, such as a former formed from metal, ceramic, or plastic, is prepared. The former is dried by transporting it through a preheated oven (not shown) to remove residual water. The preheated former is then immersed in a bath (shown at 62) containing a coagulant, a powder source, a surfactant, and water. The coagulant can include calcium ions (eg, calcium nitrate) to break the emulsion defense system, thereby allowing the latex to be deposited on the former. The powder can be calcium carbonate, which later functions as a remover. Surfactants improve wettability, especially in the cuff region, to avoid the formation of meniscus and trapped air between the former and the deposited latex. As noted above, the former is preheated in the drying stage, and the residual heat dries the water, leaving, for example, calcium nitrate, powdered calcium carbonate, and surfactant on the surface of the former. Other suitable coagulant solutions are also described in Jung et al. US Pat. No. 4,310,928, which is hereby incorporated by reference in its entirety for all purposes.

  The coated former is then immersed in a tank containing a natural rubber latex bath (shown at 64). Baths include, for example, natural rubber latex, stabilizers, antioxidants, curing activators, organic accelerators, vulcanizing agents, and the like. The stabilizer can often be a phosphate type surfactant. Antioxidants can be phenolic, such as 2,2'-methylenebis (4-methyl-6-t-butylphenol). The curing activator can be zinc oxide. The organic accelerator can be a dithiocarbamate. The vulcanizing agent can be sulfur or a sulfur-containing compound. When using these materials, stabilizers, antioxidants, activators, accelerators, and vulcanizing agents may be dispersed in water using a ball mill to avoid powder formation. This dispersion is then mixed with the latex. The former is immersed in the latex bath one or more sufficient times to form the desired thickness on the former. By way of example, the substrate body 24 may have a thickness of about 0.004 inches to about 0.012 inches.

  A bead roll station (not shown) is utilized in some embodiments to form a cuff in the glove. For example, a bead roll station can include one or more bead rolls through which the former is assigned and cuffs are formed. The latex coated former is then dipped into a dipping tank in which hot water is circulated to remove residual calcium nitrate contained in natural latex (not shown) and water soluble components such as protein. . This dipping process is continued for about 12 minutes with the water in the tank at a temperature of about 120 ° F. In addition, the latex coated former is then dipped into the solution (indicated by 66) to form the glove's doning layer 30. In one embodiment, for example, the gloves are turned over again and immersed in 1,2 syndiotactic polybutadiene compounds.

  The latex-coated former is then sent to a curing station where natural rubber is typically vulcanized in an oven, thereby thermally curing the rubber (not shown). The curing station first evaporates any water remaining in the latex coating on the former and then continues to high temperature vulcanization. Drying may be performed at a temperature of about 85 ° C. to about 95 ° C., and the vulcanization step may be performed at a temperature of about 110 ° C. to about 120 ° C. For example, in one embodiment, the glove can be cured in a single oven at a temperature of about 115 ° C. for about 20 minutes. If desired, the oven can be divided into four different areas and the former can be transported through areas where the temperature is rising. As one example, an oven can have four regions where the first two regions are for drying and the second two regions are primarily for vulcanization. The individual regions may be raised in increments of, for example, about 80 ° C. for the first region, about 95 ° C. for the second region, about 105 ° C. for the third region, and about 115 ° C. for the last region. be able to. In this case, the residence time of the former in the region can be about 10 minutes or so. Accelerators and vulcanizing agents contained in the latex coating the former are used to cross-link with the natural rubber therein. Vulcanizing agents form sulfur bridges between different rubber segments, and accelerators are used to speed up the sulfur crosslinking composition.

  After being cured, the former is then moved to a stripping station (not shown). At the peeling station, the gloves can be removed from the former automatically or manually. For example, in one embodiment, the gloves are manually removed from the former by being flipped when peeled from the former. Optionally, after removal from the former, the gloves can be washed with water.

  According to the present invention, a silicone emulsion can then be applied to enhance the grip characteristics of the glove. For example, in one embodiment, a silicon emulsion (eg, DC365) is first thoroughly mixed with water using a high shear mixer to form a uniform solution with the desired solid components. Thereafter, the formed emulsion can be applied to the gripping surface of the glove in different ways. For example, in one embodiment, the glove is immersed in a tumbler for a period of time (eg, 1-10 minutes) during which the gripping surface of the glove is rinsed with a silicone emulsion (indicated at 68). Can be removed. Alternatively, the gripping surface of the glove is sprayed with a silicone emulsion using a normal spray nozzle. Once the silicone emulsion is applied, the silicon coated gloves are then dried (indicated at 70). For example, in some embodiments, the silicon-coated glove is dried at a temperature from about 20 ° C. to about 200 ° C., and in some embodiments, at a temperature from about 35 ° C. to about 115 ° C.

  After the drying process, the gloves are then turned over and halogenated (indicated at 72). Halogenation (eg chlorination) is done by any suitable technique known to those skilled in the art. These methods include (1) direct injection of chlorine gas into the water mixture, (2) mixing of high density bleaching powder and aluminum chloride with water, and (3) chlorination to form chlorinated water. Electrolysis, (4) acidified bleaching. Examples of these methods include Kavalir et al., U.S. Pat. No. 3,411,982, Agostellili et al., U.S. Pat. No. 3,740,262, Homsy et al., U.S. Pat. No. 3,992,221, and Momose et al. U.S. Pat. No. 4,597,108, U.S. Pat. No. 4,851,266 by Momose et al., U.S. Pat. No. 5,792,531 by Littleton et al., All of which are incorporated by reference for all purposes. Is incorporated here. In one embodiment, for example, chlorine gas is injected into the water stream and then delivered to a chlorinator (sealed container) containing gloves. In order to control the degree of chlorination, the chlorine concentration is observed and controlled. The chlorine concentration is typically at least about 100 ppm, in some embodiments from about 200 ppm to about 3500 ppm, and in some embodiments, from about 300 ppm to about 600 ppm, such as about 400 ppm. The duration of the chlorination stage can also be controlled by the degree of chlorination, for example in the range of about 1 to about 10 minutes, for example 4 minutes. Due to the silicone emulsion applied to the gripping surface, the degree of chlorination is generally much greater on the wearer contact surface, i.e. the glove wearing side, than the gripping surface of the glove.

  Further in the chlorinator, the chlorinated gloves can then be rinsed with running water at about room temperature (not shown). This rinsing cycle can be repeated as needed. When all the water has been removed, the gloves are tumbled to gradually remove excess water.

  The lubricating solution is then added to the chlorinator containing the gloves and tumbled for about 5 minutes (shown at 74). Thereby, the doning side is covered with the lubricating solution, and the lubricating layer 32 is formed. In one embodiment, for example, the lubrication layer 32 may be a silicone emulsion used to form the outer layer 36, such as DC365 (Dow Corning) or SM2140 (GE Silicones), as described in detail above. Similar silicone emulsions can be included. The lubricating solution is gradually drained from the chlorinator and reused if desired.

  The coated gloves are then sent to a dryer to dry the wearing surface (not shown) and dried at about 20 ° C. to about 80 ° C. (eg 40 ° C.) for about 10 to 60 minutes (eg 40 minutes). Is done. The gloves are then turned over again and the gripping surface is dried at about 20 ° C. to about 80 ° C. (eg, 40 ° C.) for about 20 minutes to about 100 minutes (eg, 60 minutes).

  While various configurations and techniques for forming elastomeric articles have been described above, it is understood that the present invention is not limited to any particular configuration or technique for forming articles. Should be. For example, the layers described above are not used in all cases. Additionally, other layers not specifically shown above can also be utilized in the present invention.

  Thus, as described above, the outer layer of the glove can be formed using a silicone emulsion to enhance the gripping characteristics. In particular, silicone emulsions prevent the ability of halogen atoms to adhere to the elastomeric material of the substrate, thereby limiting the slipperiness normally imparted during chlorination. Surprisingly, it has been discovered that materials that may be used to increase wet lubricity of the contact surface with the wearer have the opposite effect when used when forming the outer layer of a glove. It was. This discovery not only enhances the gripping characteristics of the gloves to be enhanced, but also gives the possibility of using similar materials in the lubrication layer on the contact surface with the wearer and the outer layer on the gripping surface, This will reduce costs and increase efficiency.

Chlorine gas mixed with a stream of water was injected into the chlorinator to chlorinate the glove wearing surface. The chlorine concentration was 400 ppm and the pH was 1.74. The gloves were immersed in the chlorine solution for 2 minutes. In this particular example, cetylpyridinium chloride was also added to the chloride solution at a concentration of 0.25% by weight of the solution. After chlorination, the gloves were turned over and dried at a temperature of about 80 ° C. for 45 minutes.

  The glove sample described above was then tested to determine the grip characteristics of the glove. In particular, gloves were first worn on wet hands. After wearing the gloves, the wearer ranked the adhesiveness of the gripping surface of the glove on a scale of 1-5 by repeating the optimum adhesive conditions four times.

The SM2140 solution (1.0 wt% solids component) was applied to the glove wearing surface as a lubricating layer using a rolling method. Specifically, 4 grams of SM2140 (25% solids component) was added to 96 grams of water to form a uniform solution with 1.0% solids component. The gloves were then immersed for 5 minutes in a tumbler infused with diluted SM2140 emulsion.
