  • Patent number: 11723427
    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.

  • Patent number: 11337472
    Abstract: A glove is provided that enables suppression of cracks in a coating layer containing nitrile butadiene rubber as a principal component. The glove comprises: a glove main body made of fibers for covering a wearer's hand; and a coating layer which comprises nitrile butadiene rubber as a principal component and coats at least a part of an outer face of a palm region of the glove main body, in which: the coating layer comprises zinc oxide and a cross-linked product of the nitrile butadiene rubber and polycarbodiimide; and a mass ratio of the polycarbodiimide to the nitrile butadiene rubber is no less than 0.002. The mass ratio of the polycarbodiimide to the nitrile butadiene rubber is preferably no greater than 0.09. The content of the zinc oxide with respect to 100 parts by mass of the nitrile butadiene rubber is preferably from 0.3 to 5 parts by mass.

  • 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: 10612168
    Abstract: Provided is a glove superior in breathability, sweat-absorbent and quick-drying properties, and wearing feel. The glove comprises a knitted fabric constituted from stitches arranged successively in a course direction and engaged with corresponding stitches in a wale direction. The knitted fabric comprises at least one irregular surface portion comprising tucked parts arranged in a scattered manner, and at least one rib portion in proximity to the irregular surface portion and provided along the course direction. The tucked parts are preferably arranged uniformly in both the course direction and the wale direction in the irregular surface portion. The rib portion comprises: a cylindrical rib main body part constituted from stitches arranged successively in the course direction and engaged with corresponding stitches arranged in the wale direction, with a region between base ends being contracted; and a filling part subsequent to the rib main body part in the course direction.
