Abstract: A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high S8 ring structure that is catalytically broken by a zinc dithiocarbamate. Surfactants present in the pre-vulcanization composition wets synthetic polyisoprene particles and permeates small sized sulfur and accelerator molecules into the interior of these particles thereby pre-vulcanizing the particles. The degree of pre-vulcanization is verified by isopropanol index test. The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle. The dipped synthetic polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds in TEM and zinc segregation at the boundaries or original particles by electron microprobe analysis. The films exhibit high tensile strength, tensile modulus, tear strength, burst pressure and burst volume.

Abstract: A latex glove article with a fibrous coating bonded to the skin-contacting surface. Long length soft moisture absorbing fibers are attached to latex layer of a glove with a thin layer of polymeric latex adhesive forming a fibrous lining. The long length fibers have a length ranging from 4 to 100 times the thickness of the polymeric latex adhesive layer and therefore extend or project from the polymeric latex adhesive coating. The fibers penetrate the polymeric latex adhesive layer at one end or both end of the fiber to a depth of about 60% to about 100% of the adhesive thickness, leaving a substantial portion of the fiber available for soft contact with skin and sweat absorption. Due to the substantial thickness of the fibrous lining, an air gap is created between skin and the impervious latex layer establishing continual evaporation of absorbed sweat and evaporative cooling.
Abstract translation: 具有粘合到皮肤接触表面的纤维涂层的乳胶手套制品。 长度柔软的吸湿纤维通过形成纤维衬里的聚合物胶乳粘合剂薄层附着在手套的胶乳层上。 长纤维的长度为聚合物胶乳粘合剂层的厚度的4至100倍，因此从聚合物胶乳粘合剂涂层延伸或突出。 纤维在纤维的一端或两端穿透聚合物胶乳粘合剂层至粘合剂厚度的约60％至约100％的深度，留下大部分纤维可用于与皮肤的软接触和吸汗。 由于纤维衬里的厚度很大，皮肤和不透水乳胶层之间产生气隙，从而建立吸收的汗水和蒸发冷却的连续蒸发。
