  • Moisture retentive gloves and process for producing the same
    Patent number: 7891022
    Abstract: Moisture retentive gloves characterized by using fibers treated with a moisture retentive component as fibers of an internal surface of gloves fabricated of a rubber or a synthetic resin. In particular, moisture retentive gloves wherein the fibers of an internal surface of gloves are staple fibers bonded to the internal surface of glove base material fabricated of a rubber or a synthetic resin, some or all of the staple fibers treated with a moisture retentive component; and moisture retentive gloves wherein the fibers of an internal surface of gloves are fibers of gloves fabricated of a cloth as a raw material of the gloves, some or all of the fibers constituting the cloth gloves treated with a moisture retentive component. These moisture retentive gloves, even if used repeated times and used for a prolonged period of time, do not affect the normal bacteria on the skin by virtue of the action of the moisture retentive component retained on the fibers, so that hand skin chapping or the like can be prevented.
