Definitions

  • the protective gloves for process industries are constructed to assure people safety under harsh chemical, mechanical and electrical conditions.
  • the glove suppliers provide a big product catalog, where different types of gloves are recommended for different type of chemicals to be handled. Depending on the application and chemical products to which they are exposed, the gloves may have a different type of material and a different thickness of the layers from which they are made of.
  • the gloves In many countries, such as European countries, the gloves have to pass mechanical (EN 388), thermal (EN511), and chemical standards, such as a European standards (EN 374-2, EN 374-3) before they are sent to the market.
  • the gloves should comply with the standard EN 420, which specifies general criteria for comfort, size, dexterity, labeling, and heavy metal content and pH content.
  • EN 420 specifies general criteria for comfort, size, dexterity, labeling, and heavy metal content and pH content.
  • Each standard defines exact test and acceptance conditions for the gloves exposed to critical mechanical, thermal, chemical agents.
  • the standard EN-374-2 characterizes the permeability features of the gloves and it specifies a method for testing the protective gloves resistance to permeation of chemical products (penetration).
  • Standard EN374-3 includes the standard.
  • This performance level 2 for chemical resistance means that the permeation time (test made according to the standard) should be higher than or equal to 30 minutes, when the glove is exposed continuously to that chemical.
  • Such latex gloves meet the above standard and they are also accompanied by a wide list of permeation data.
  • their use in the field is made most of the time without keeping clear evidence of the time of use during their lifetime, and so in many cases they can be used for a much shorter time with respect to their designed lifetime.
  • the suppliers themselves may be conservative in specifying the level of performance, which means that even if the real level of performance may be 4, the supplier would specify 3, which is lower than 4.
  • An inner indicator glove formed of multiple layers including a protective layer having a top surface and a bottom surface, the bottom surface facing a hand of a user when wearing the inner indicator glove, and an indicator layer supported by the top surface of the protective layer and positioned to contact protective glove when the inner indicator glove is inserted into the protective glove, wherein the indicator layer is formed of a material that changes color when exposed to a solution penetrating the protective glove.
  • a method of forming an inner indicator glove including dip coating a hand shaped former into a bath to form a protective-layer having a thickness that provides a selected protection time less than a protection time of a protective glove and forming an indicator layer on the protective layer, the indicator forming an outer layer of the inner indicator glove.
  • a method includes inserting an inner indicator glove into a protective glove, wherein the inner indicator glove has an indicator layer positioned to change color responsive to an end of service life of the protective glove, using the protective glove with the inserted inner indicator glove, viewing the change of color of the indicator layer, and discontinuing use of the protective glove.
  • FIG. 1 is a block diagram illustrating a protective outer glove and inner indicator glove for use inside the protective outer glove according to an example embodiment.
  • FIG. 2 is a cross section representation of a portion of an inner indicator glove according to an example embodiment.
  • FIG. 3 is a block diagram of a protective outer glove having a transparent patch for viewing an inner indicator glove color according to an example embodiment.
  • FIG. 1 is a representation of a protective glove 100 to be used in conjunction with an inner indicator glove 110 that fits inside of protective glove 100 .
  • the protective glove may be formed of latex or other protective material, like nitrile, chloroprene (e.g. Neoprene, butyl, polyvinyl chloride (PVC), PU, CSM, Fluoro elastomer (e.g. Viton).
  • chloroprene e.g. Neoprene, butyl, polyvinyl chloride (PVC), PU, CSM, Fluoro elastomer (e.g. Viton).
  • PVC polyvinyl chloride
  • CSM Fluoro elastomer
  • the inner indicator glove 110 is introduced into the outer protective glove (G2G-glove to glove).
  • the inner indicator glove 110 is designed to indicate the permeation of harsh chemicals through the outer glove and to assure hand protection for a minimum amount of time, such as at least 10 minutes of work (performance level 1).
  • FIG. 2 is a cross section view of a portion 200 of the inner protective glove 110 .
  • the inner protective glove 110 in one embodiment is thin and flexible, comprising two layers, a top layer 210 and a bottom layer 220 , strongly adhering one to the other, being stacked together during a fabrication process.
  • the bottom layer 220 is formed of protective material having a thickness suitable for ensuring protection of a hand for a specified amount of time following failure of the protective glove 100 , such as 10 minutes. Other times, such as 5 minutes, 15 minutes, or any other time may be selected. Note that the protective bottom layer 220 may be quite a bit thinner than the thickness of the protective glove 100 .
  • Top layer 210 of the inner indicator glove is made of a material which changes its color due to the pH of the liquid permeating through the outer glove.
  • a color changing layer can be made of universal pH indicator, and may thus respond to any type of chemical, either acid or base and its mixture.
  • a good example for such universal pH indicator is the bromophenol blue. According to the color change of the bromophenol blue exposed to the liquid, a yellow color is obtained for pH smaller than 3, multiple colors for pH between 3 and 4.6 (real pH indicator in this pH range) and blue color for pH greater than 4.6.
  • the advantage of bromophenol blue is that it has the largest change in color hue, when the concentration of the observed sample increases or decreases.
  • top layer 220 of the inner indicator glove 110 If for example one needs a indicator to be used for the top layer 220 of the inner indicator glove 110 immersed only in the acid baths, then one can use a color changing layer (top layer 220 ) based on methyl orange (C 14 H 14 N 3 NaO 3 S) which indicates the presence of acids (pH between 0 and 6), discriminating very well the strength of the acid. For other applications, where only bases are handled, one can have a color changing layer based on phenolphthalein, which is colorless below 8.2 and pink above that value up to a pH of about 13. For even stronger basic solutions, the phenolphthalein becomes colorless.
  • the bottom layer 220 of the inner glove which is in contact with the skin, it is made of a chemically resistant material like latex, butyl, CSM/neoprene, etc.
  • Such an inner indicator glove 110 with continuous color change top layer 220 above the entire hand has the advantage of identification of the starting leakage area without any harmful effect of on the skin of the user, while the outer protective glove itself has been safely used during its maximum service life, without any concerns related to its use in the last period of use.
  • Determining that the inner indicator glove 110 has changed color may be done in several different ways.
  • the user may simply remove the outer protective glove 100 and visually inspect the inner indicator glove 110 for color changes.
  • a transparent or at least partially transparent or translucent patch may be provided on an alternative outer protective glove 300 as indicated at 310 in FIG. 3 .
  • the patch 310 is sufficiently transparent to allow a user to see the color of the inner indicator glove without removing the outer glove.
  • the activation mechanism causing the inner indicator glove to produce a visible indication results in a flow of an indicator solution comprising vapors and liquids the external glove is exposed to, to an external surface of the protective glove.
  • an indicator solution comprising vapors and liquids the external glove is exposed to, to an external surface of the protective glove.
  • nanopores which are filled with air, and these nanopores are at the origin of the liquid permeation process. This means that the liquid molecules can diffuse inside the protective glove via those pores and after a certain time they can penetrate the entire thickness of the protective glove, reaching the inner indicator glove. This time is called the breakdown time of the protective glove in a certain solution. The breakdown time of a protective glove will depend on its thickness, the magnitude of the permeating liquid molecule and the size of the nanopores.
  • the solution from the nanopores will start to dissolve the color changing indicator layer 210 containing bromophenol blue in one embodiment in the inner indicator glove 110 , acting as a pH indicator or dye. This dye will start diffusing back along the nanopores via concentration gradient and capillary forces, through the protective glove 100 until visible at the outer surface of the protective glove 100 .
  • a background color of white for the protective glove 110 may provide for maximum contrast of the indication color.
  • the color will be changed according to the overall pH of the liquid in the pores after glove exposure to both acids and bases, and solvents, i.e., the solution.
  • the first fabrication process is similar to a traditional dip coating process used for the protective glove.
  • a second process is a hybrid approach where the chemically resistant layer is made by dip coating while the color changing layer is made by direct printing.
  • the third process is an all-printing process, where both color changing layer and the chemically resistive layer are made by a method of direct printing.
  • This G2G concept can be applied to all types of chemically protective gloves.
  • a universal inner indicator glove can be used for all type of gloves dedicated to acid/base/solvent combinations.
  • HSF hand shaped former
  • the hand shaped former is in the shape of a typical glove, having portions corresponding to an arm, palm area, four fingers and a thumb.
  • Different HSFs may be used for each hand and multiple HSFs may be used of varying sizes corresponding to different sizes of hands and protective gloves.
  • a thermal treatment is made for the solid state consolidation of the film.
  • the gloves are peeled off from the HSF, and thus the last deposited layer on the glove will be the layer in contact with the skin.
  • the glove is not reversed when peeling it off from the HSF, or may be turned inside out after peeling off. This allows the inner indicator glove to be formed by first forming the latex protective layer followed by the indicator layer.
  • the same size HSF may be used to form both the protective glove 100 and the inner indicator glove 110 such that a tight fit of the inner indicator glove 110 into the protective glove 100 is obtained.
  • a tight fit ensures better tactile feel and dexterity for the user in utilizing the combined gloves.
  • a tight fit may also promote better migration of color from the inner indicator glove to the outside of the protective glove for viewing by a user.
  • a slightly smaller size HSF may be used for the inner indicator glove formation.
  • HSF hand-shape former
  • Direct printing of the color changing layer is possible.
  • Direct printing such as by inkjet printer allows the color changing layer to be masklessly deposited.
  • An automated factory for fabrication of all printed inner indicator gloves utilizing moving the HSF on a line from one location to another, and at each location, the HSF will receive the required process as described above.
  • the HSF can travel through a furnace with the required temperature profile, as required by the previous printed layer.
  • a method of forming an inner indicator glove comprising:
  • bromophenol blue slurry comprises bromophenol blue powder, alcohol, a surfactant, and a viscosity intensifying agent resin.
  • a method comprising:
  • viewing the change of color of the indicator layer comprises removing a portion of the protective glove to expose the inner indicator glove such that the change of color is visible to a user.
  • viewing the change of color of the indicator layer comprises viewing a solution that diffused back through nanopores in the protective glove to an outer surface of the protective glove, the solution being colored by the indicator layer responsive to the solution penetrating the protective glove signifying the end of the service life of the protective glove.
  • viewing the change of color of the indicator layer comprises viewing the indicator layer through a transparent patch of the protective glove.
