Definitions

  • Single use disposable gloves have been widely used in many fields and industries to provide necessary hand protection and to avoid cross contamination. It is a common practice to frequently change gloves, because thin wall gloves may fail after a prolong period of time, or cross contamination may be induced with more than one substance or object being handled.
  • warning indicator It is desirable to have some kind of warning indicator to provide better protection. There are a number of mechanisms and methods that have been produced.
  • a glove with multiple layers can be made with a colored liquid in between the layers, as shown in U.S. Patent 6,370,694. Once the glove is punctured half way through, the colored liquid will flow out and be seen.
  • Another example is a glove with multiple layers with a vacuum in between. Once the glove is punctured halfway through, the glove becomes inflated.
  • U.S. Patent No. 6,744,368 describes another breach detecting glove. Again, a liquid is sealed in between multiple layers, and a microchip is embedded into gloves. Once the glove fails, the sealed in liquid will activate the microchip which, in turn, will communicate the compromised integrity of the glove to the wearer.
  • Thin wall gloves have color change time indicators.
  • a color change label or friendly reminding message can be seen after the glove is put on for a period of time.
  • the warning indicators can be triggered via UV, visible light, temperature change, air exposure, presence of oxidizers (oxygen, chlorine), pH change, chemical reaction of two components or any combination of these activators.
  • the method for producing these gloves can be easily realized under common glove production lines. Depending on the desired applications, both powdered and powder free gloves can be produced.
  • Figure 1 displays a glove having an activated warning sign
  • Figure 2 displays a glove having an appearing warning sign
  • Figure 3 displays a glove having a progressive warning sign.
  • the triggering mechanism can be exposure to light, heat, moisture, chemical reaction of two components, and some component of air, such as oxygen or carbon dioxide.
  • Colorless indication can be one end of a color changing process as well. In other words, an indicator can appear or disappear upon being triggered. Because the color changing is also environment dependent, the gloves will not pinpoint the exact time. Instead, a rough range is specified: less than 30 minutes, 30 - 60 minutes, and longer than 1 hour, and so on. Additionally, the indicator can show a first color at less than 30 minutes, a second color between 30 - 60 minutes, and a third color when longer than 1 hour. The color changing is gradual, and not a sharp change.
  • the ink is added into the glove dipping compound, the whole glove will change color over time.
  • the ink can be sprayed on a certain portion of the glove.
  • a company logo can be sprayed onto the glove and it can be made to disappear as the indicator, or a message such as Atime to change@ can be made to appear.
  • the inks can also be provided separately for glove wearers as stamps or self-stickers. The glove wearers can apply them at the time they put the gloves on, or as desired.
  • Figures 1 to 3 show the gloves with indicators incorporated therein. They demonstrate color change before and after activation, via various triggering mechanisms.
  • Figure 1 depicts a glove 10 having a colored warning symbol 14 changing from a first color, seen in Figure 1a to a second color, seen in Figure 1b, indicating that the glove needs to be changed.
  • Figure 2a depicts a glove 10 having a warning symbol 16, which may be a message, appearing, as shown in Figure 2b to indicate that the glove need to be changed. This would work in reverse for a symbol that disappears when the glove needs to be changed.
  • Figures 3a-c shows a progressive symbol 18 on glove 10 changing colors over time to give an indication of elapsed time.
  • the glove displays a first color, shown in figure 1a for the first 30 minutes of use, a second color seen in figure 3b from 30-60 minutes of use and a third color, seen in Figure 3c after 60 minutes.
  • the colors displayed by the gloves are a function of the material used for the warning sign.
  • the demonstrated methods can be applied to all disposable gloves, such as natural rubber latex, nitrile butadiene rubber, polyisoprene polychloroprene, polybutadiene rubber, butyl rubber, polyvinyl chloride, polyurethane, styrene ended copolymer thermal elastomers, as well as their blends, copolymers, and multiple structured composites.
  • These methods are independent from the glove matrix materials involved and can be applied to gloves either on-line or off-line. This gives great flexibility to the glove manufacturers to implement the processes.
  • UV sensitive material sometimes called photo chromatic material
  • photo chromatic material is sensitive to UV light.
  • the color of the material changes when exposed to a UV light source, such as sunlight.
  • photo chromatic materials When photo chromatic materials are exposed to UV light, they absorb the energy and use that energy to change their molecular structures.
  • the new structures will have different color absorption and reflection abilities than the original structures. Thus, visible color changing occurs. This depends on the materials used.
  • a color change can also be altered and the time span for the color change is adjustable.
  • the color change process can be reversible, molecular structure changes back to original once UV light is absent, or irreversible, once the molecular structure is changed by UV source, it remains at new form even when UV source is absent.
  • UV sensitive indicator is a mixture of dye pigment and UV activated materials such as the spiro-indoline-oxazines family, for example CTI Photo UV yellow, a commercially available material from Chromatic Technologies, Inc.
  • fluorescent light sensitive materials are sensitive to fluorescent light such as indoor visible light.
  • the mechanism is very similar to the UV mechanism. The only difference is that visible light activates the molecular structure change of the material, resulting in a visible color change. A different color change can be achieved using different materials. Again, the color change process can be reversible or irreversible and depends on different chemicals used.
  • One possible material usable as a visible light sensitive indicator is a mixture of dye pigment and silver salts, for example C WC Ag 1, a commercially available material from Spectra Group Limited, Inc..
  • the manufacturing operation can be conducted with limited red light exposure.
  • pH indictors used for acid base titration.
  • One is thymolphthalein, colorless at pH ⁇ 9.3 and dark blue at pH > 10.5.
  • the indicator system also contains sodium hydroxide, a commonly used base. It adsorbs any accessible acidic substance. In the application to a glove, the indicator goes from dark blue to colorless.
  • the chemical reaction upon air exposure is as follows:
  • a carbon dioxide sensitive indicator is a mixture of a pH indicator, such as thymolphthalein and base or acid solution, such as sodium hydroxide and sold by Penguin Magic Inc. as Disappearing Ink.
  • Indicators for oxidation-reduction titration can serve as time indicators. Similar to carbon dioxide sensitive gloves, airtight storage has to be adopted.
  • One possible material used as a oxygen sensitive indicator is a mixture of thiazone dye pigment and aliphatic organic compounds, such as RP Systems oxygen indicators from Mitsubishi Chemicals.
  • the glove has to gain an extra component from the environment; energy such as light or heat or components form the air such as oxygen and carbon dioxide.
  • the gloves can be made with certain components inside or on the a glove. They can provide some other ingredients separately as a self-sticker. The glove wearer can apply this self-sticker onto the glove after the glove is put on. Once the contact between the reactive ingredients occurs, the desired color change would result over a predetermined period. This would allow a more flexible and friendly manufacturing and storage requirement.
  • a chemical reaction activated indicator is a mixture of dye pigment, alkaline substance and ascorbic acid and salt, for example TT sensor, a commercially available chemical reaction activated indicator from Avery Dennison.
  • an oxidation-reduction titration indicator can be combined with a sodium chlorite. Upon light exposure, sodium chlorite will decompose and release chlorine and chlorine dioxide. Both are strong oxidizers causing color change of many oxidation-reduction indicators.
  • the indicators can be single component and multiple components. It can be entirely or partially embedded into a glove. It can have components separately as self-stickers. It can be ingredients of a glove-dipping compound and can be sprayed over the surface.
  • the visual change can be a simple color change from one color to another color with one of the colors bring colorless, or a sign appearing or disappearing.
  • the color indication can be any symbol, a company logo, or a message and could encompass the entire glove.
