  • Publication number: 20230301386
    Abstract: A method for producing a supporting glove includes the steps of applying a specific amount of a first polymer mixed liquid to a knitted glove; drying the first polymer mixed liquid applied to the knitted glove; applying a coagulant solution to the knitted glove after drying; applying a specific amount of a second polymer mixed liquid to the knitted glove after applying the coagulant solution; and drying the second polymer mixed liquid applied to the knitted glove. A first polymer film is formed to cover a yarn knitted into the knitted glove over the entire thickness direction of at least the part of the knitted glove. A second polymer film is formed to continuously cover the first polymer film to form at least a part of an outer surface and not reaching an inner surface of the knitted glove.

  • Publication number: 20230165329
    Abstract: An object of the present invention is to provide a glove in which a glove main body and a film are less likely to peel from each other even when a load, especially a torsional load, is applied. A glove according to an aspect of the present invention includes: a glove main body made of fibers; a film which covers at least a part of an outer face of the glove main body and contains a rubber or a resin as a principal component; and an adhesive portion which bonds the glove main body and the film together, wherein the adhesive portion includes: a pressure-sensitive adhesive layer in contact with the film; and an adhesive layer which is in contact with the glove main body and is constituted by a hot-melt adhesive.

  • Patent number: 10856592
    Abstract: A glove with a sleeve is provided in which the bonding strength between the glove main body and the sleeve is great, allowing easy wearing and removal as well as easy overlapping of the glove main body and the sleeve upon bonding. The glove with a sleeve includes: a glove main body compromising rubber or a resin as a principal component; and a cylindrical sleeve comprising a thermoplastic resin as a principal component that is arranged to protrude from a cuff portion of the glove main body, in which the cuff portion of the glove main body is bonded to one end portion of the sleeve through a moisture-curing urethane-based hot melt adhesive. The moisture-curing urethane-based hot melt adhesive is preferably crosslinked. A post-curing thermal deformation temperature of the moisture-curing urethane-based hot melt adhesive is preferably no less than 80° C.

  • Patent number: 10010124
    Abstract: A glove includes: an inner glove knitted from a fiber yarn; an outer glove that covers an outer side of the inner glove; and a hot-melt adhesive interposed partially between the inner glove and the outer glove which are layered, the outer glove including: a base knitted from a fiber yarn; and a coating layer layered on an outer face of the base and composed of a rubber or resin as a principal component; and the inner glove and the outer glove are bonded together by first heating the hot-melt adhesive applied onto a bonding portion on the inner glove or the outer glove, and then cooling and pressurizing the bonding portion. The inner glove is preferably a knitted product. The inner glove is preferably seamless. The cooling temperature during the cooling and pressurizing is preferably no higher than a softening point of the hot-melt adhesive.
