Definitions

  • the invention relates to method of manufacturing a glove and a glove, which glove comprises top layer, an outer surface and an inner surface, which inner surface is configured to be in skin contact when the glove is worn in hand.
  • Pathogens such as bacteria and viruses cause diseases, which may be difficult to cure and require a long time to recover. Some diseases may even fatal.
  • On way to reduce the risk of having a contamination of harmful pathogens is to wear gloves. By wearing gloves skin contacts with possibly contaminated surfaces can be reduced. Gloves are widely used in occupations and workplaces, where there is an increased risk of being infected by harmful pathogens.
  • the gloves used to reduce infection risk are disposable, i.e. they are not intended to be reused after removal.
  • Disposable protective gloves are difficult to put on and take off and their mechanical durability is weak. Gloves are effective in avoiding contamination only, if the hands are disinfected before the gloves are put on. Therefore, gloves lose their protective effect easily in everyday use, where occasional removing the gloves is necessary. Problems relating to the use of the disposable gloves lower the willingness of the people to use gloves for protection.
  • An object of the invention is to provide a method for manufacturing a glove and a glove, with which drawbacks relating to the prior art can be reduced.
  • the present invention relates to a method of manufacturing a glove, which glove comprises top layer, an outer surface and an inner surface, which inner surface is configured to be in skin contact when the glove is worn in hand.
  • Said method comprises a step of providing the inner surface with pathogen inactivating compounds whereby the inner surface is treated with a substance containing pathogen inactivating compounds, said substance comprising solvent and coniferous resin acids in the range of 0,01 to 30 weight-% of the substance.
  • the method comprises a step of manufacturing a lining, said lining having an inner surface and attaching the lining inside the top layer, whereby the inner surface of the lining forms the inner surface of the glove.
  • liquid containing pathogen inactivating compounds is sprayed on the inner surface and the sprayed liquid is allowed to dry to a coating at least partly covering the inner surface.
  • the glove is soaked in a liquid containing pathogen inactivating compounds to impregnate the glove with pathogen inactivating compounds and the soaked glove is allowed to dry.
  • the lining is soaked in a liquid containing pathogen inactivating compounds to impregnate the lining with pathogen inactivating compounds and the soaked lining is allowed to dry.
  • the lining is soaked in a liquid containing pathogen inactivating compounds before the lining is attached inside the top layer.
  • the lining is manufactured of fabrics or of threads which fabrics or threads are treated with a substance containing pathogen inactivating compounds before the lining is manufactured.
  • the top layer is treated with a substance containing pathogen inactivating compounds before the lining is attached inside the top layer.
  • a glove according to the invention comprises a top layer, an outer surface and an inner surface, which inner surface is configured to be in skin contact when the glove is worn in hand.
  • Said inner surface contains pathogen inactivating compounds, wherein said pathogen inactivating compounds comprise coniferous resin acids.
  • the glove comprises a lining inside the top layer, said lining having an inner surface, whereby the inner surface of the lining forms the inner surface of the glove.
  • the inner surface has a coating comprising pathogen inactivating compounds.
  • the top layer and/or the lining is impregnated with pathogen inactivating compounds.
  • the top layer is made of leather or textile and the outer surface of the glove has a coating comprising pathogen inactivating compounds.
  • An advantage of the invention is, that it reduces the risk on being infected by pathogens in everyday situations.
  • Another advantage of the invention is, that the reduces the need and use of disposable gloves, which saves material and environment.
  • a further advantage of the invention is, that it reduces the need of using disinfectants.
  • FIG 1a an embodiment of the glove according to the invention is shown oblique from above.
  • fig. 1b a cross-section the glove of fig. 1a along line A-A is depicted. In the following both figures are explained simultaneously.
  • the glove is a known handheld garment comprising a top layer 10, which has a shape of a hand.
  • the top layer can be made by knitting or by sewing cutted pieces of fabrics or leather together to a desired shape. Further, it is possible to make the top layer from castable material, such as natural or synthetic rubber or plastic by using a mould having a shape of a hand.
  • the top layer 10 has an outer surface 12 and an inner surface 14 ( fig. 1b ).
  • the inner surface is defined to be the surface, which is configured to be in skin contact, when the glove is worn in hand.
  • the outer surface is the surface of the top layer, which remains visible, when a hand is inserted inside the glove.
  • the inner surface 14 is treated with a substance containing pathogen inactivating compounds.
  • pathogen inactivating compounds adhere to inner surface forming a pathogen inactivating coating covering substantially the whole area of the inner surface.
  • Pathogens may include bacteria, viruses and/or fungus. Inactivating here means making the pathogens harmless either by killing them or by significantly reducing their ability to reproduce on animate or inanimate surface and/or infect a human being.
  • the treatment can be made by immersing the substantially finished glove into a liquid containing pathogen inactivating compounds. The soaked glove is then lifted out of the liquid and allowed to dry completely. When the glove dries the molecules of the pathogen inactivating compounds form a dense network on the inner surface and on the outer surface of the clove. If the top layer is knitted or woven fabric or textile or other fibrous material, which is water permeable, the compounds form a covering around the fibres of the top layer. Thus, the whole top layer material becomes impregnated with pathogen inactivating compounds.
  • top layer is made of substantially waterproof material, such as leather, natural or synthetic rubber, plastic, water repellent or waterproof fabric or PU-coated textile, a coating in a form of thin molecular net containing pathogen inactivating compounds is formed and adhered to the inner and outer surfaces of the glove.
  • substantially waterproof material such as leather, natural or synthetic rubber, plastic, water repellent or waterproof fabric or PU-coated textile
  • the treatment with a substance containing pathogen inactivating compounds is made by spraying liquid containing pathogen inactivating compounds on the inner surface 14 of the glove and allowing the sprayed liquid to dry to a coating on the inner surface.
  • a single spray treatment comprises a number of consecutive sprayings and a drying period between each spraying.
  • the number of sprayings in a single spray treatment may be 10 to 20, preferably 15.
  • the drying period between each spraying may be 5 to 10 minutes.
  • the top layer of the glove can be turned inside up for the duration of the spray treatment.
  • a similar spray treatment can be made for the outer surface of the glove also.
  • FIG 2a a second embodiment of the glove according to the invention is seen oblique from above.
  • fig. 2b a cross-section the glove of fig. 2a along line B-B is depicted. In the following both figures are explained simultaneously.
  • the embodiment of the glove depicted in figs. 2a and 2b differs from the embodiment of figs. 1a and 1b in that it further comprises a lining 18 inside the top layer 10.
  • the lining and the top layer have a substantially similar shape, but the lining is slightly smaller, which makes possible to insert the lining inside the top layer.
  • the inner surface of the glove which is defined to be the surface, which is configured to be in skin contact, when the glove is worn in hand, is now the inner surface 14a of the lining 18.
  • the lining is usually made of soft knitted or woven fabric or textile.
  • the lining is attached to the top layer 10 by joint knitting 16 locating in the edge of the wrist surrounding area of the glove.
  • the treatment for a glove shown in figs 2a and 2b with a substance containing pathogen inactivating compounds can be made in a similar way as to the gloves shown in figs. 1a and 1b , i.e. by immersing the substantially finished glove into a liquid containing pathogen inactivating compounds and allowing glove to dry completely.
  • the water permeable lining material becomes impregnated with pathogen inactivating compounds and on the inner surface 14a of the lining a coating containing pathogen inactivating compounds is formed.
  • the top layer becomes impregnated in a similar manner.
  • top layer is made of substantially waterproof material, such as leather, natural or synthetic rubber, plastic, water repellent or waterproof fabric or PU-coated textile, a thin coating containing pathogen inactivating compounds is formed and adhered to the inner and outer surfaces of the top layer.
  • This soaking treatment is a possible treatment method for cloves, if the material of the outer surface of the glove can withstand soaking and wetting without harmful side-effects, such as colour chances.
  • the treatment of the lining 18 and the treatment of the top layer 10 are made in separate phases.
  • the treatment of the lining 18 can be made either by immersing the substantially finished lining into a liquid containing pathogen inactivating compounds and allowing the lining to dry completely or by spraying liquid containing pathogen inactivating compounds at least on the inner surface 14a of the lining and allowing the sprayed liquid to dry as explained above.
  • the lining can be detached from the top layer whereby it is attached to the top layer with a joint knitting 16 after the treatment of the lining is finished. It is also possible to attach the lining to the top layer before treatment and pull the lining out the top layer in a way that only a short strip of lining next to joint knitting remains inside the top layer.
  • the treatment with a substance containing pathogen inactivating compounds is performed. After the treatment is finished and the lining 18 is dry, the lining is pushed back inside the top layer. Further, it possible to treat the manufacturing materials of the lining, i.e. the yarns and fabrics, already before the manufacturing of the lining is started.
  • the substance containing pathogen inactivating compounds used in the method contains natural, biodegradable compounds, which are harmless for the human and for the environment.
  • the substance comprises solvent and coniferous resin acids in the range of 0,01 to 30 weight-% of the substance.
  • the substance comprises primary solvent, coniferous resin acids in the range of 0,01 to 30 weight %, water and an auxiliary solvent selected from E and P series glycol ethers.
  • the amount of primary solvent is preferably in the range from 50 to 95 weight -% and the amount of auxiliary solvent is preferably in the range from 0,001 weight-% to 5 weight -% of the substance.
  • Aforementioned substance has an inactivating effect to numerous bacteria and viruses including SARS, MERS, influenza virus, H1N1 and human coronavirus.
  • the substance has also proven to have adequate adhesion properties, i.e. it sticks and stays in on the inner and outer surface of the glove for an expected lifetime of the glove.
  • the used substance does not include heavy metals, borax, terbinafines, parabens or quaternary ammonium compounds.
  • the inner surface of the glove according to the invention contains aforementioned pathogen inactivating compounds.
  • the glove When the glove is used, i.e. when a hand is inserted inside the glove, the hand is in skin contact with the inner surface and the compounds therein. If the hand carries pathogens, such as bacteria or viruses, the compounds in the inners surface will soon inactivate them. Thus, a hand is disinfected each time the hand is inserter and kept inside a glove for a sufficient time.
  • the glove according to the invention may be a workglove or a leisure time glove. These kinds of gloves are usually kept in hand quite long periods, whereby the pathogen inactivating compounds easily have sufficient time to influence to the pathogens.
