A mold for casting a micro-scale structure includes an upper surface including a first cavity having a first depth. A negative pattern for an array of micro-scale structures is defined in a surface of the first cavity. The mold includes at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures. The at least one second cavity defines a negative pattern for a standoff of the micro-scale structure. A fabric retaining frame is disposed in the first cavity.

A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

An elastomeric abrasion and cut resistant coating or coated glove, including a polymeric, elastomeric, or latex layer and, optionally, a fabric liner, is disclosed. Methods for manufacturing an elastomeric abrasion and cut resistant coating or coated glove substantially are also disclosed.

An embodiment is disclosed of a method of making gloves, more particularly polyvinyl chloride (PVC) coated gloves. The method comprises providing a liner, and coating at least a part of the liner with a PVC paste to form a coating having an outer layer, applying particles of a soluble solid to the outer layer of the coating and curing the outer layer. Preferably, the method further comprises gelling the outer layer after applying the particles and contacting the gelled outer layer with a solvent before curing. Preferably, the soluble solid comprises a solid acid.

Disclosed are a method of manufacturing sport protective equipment and sport protective equipment manufactured by the method. A thin casing is manufactured by a thin sheet material in a vacuum forming process; protrusions are formed apart from one another on a surface of the thin casing; a containing space is formed on an inner side of each protrusion for filling a filler; and a substrate is provided to seal the bottom of the thin casing, so that the filler in each of the containing spaces will not fall out, so as to improve the manufacturing efficiency and the product quality. The sport protective equipment manufactured by this method does not require any sewing manufacture or increase thickness, so that the flexibility of wearing and using is improved, and the thin casing and the filler are provided for absorbing shocks to improve the protective effect.

A chemical resistant composite glove that includes a first polymeric layer in the shape of a glove; and a second polymeric layer disposed on the first polymeric layer, and wherein the first polymeric layer is specified for one class of chemical resistance and the second polymeric layer is specified for a second class of chemical resistance, and optionally a third polymeric layer, which may be a thin coating, disposed on at least one of first polymeric layer or the second polymeric layer and is optionally specified for a third class of chemical resistance.

Gloves comprising a polymeric coating or layer, optionally including a fabric liner, and at least one reinforcement, disposed on a part(s) of the polymeric coating or layer and/or ac part(s) of the fabric liner, and methods of making the gloves are disclosed.

The present disclosure relates to a manufacturing method of a waterproof glove. In more detail, the manufacturing method of a waterproof glove includes: a membrane glove manufacturing step of manufacturing a glove using a polyurethane membrane sheet applied with a hot-melt adhesive; a lining glove inserting step of inserting a lining glove into the membrane glove manufactured to the membrane glove manufacturing step; a membrane glove inserting step of inserting the membrane glove with the lining glove inserted through the lining glove inserting step into an outshell glove; and a thermal bonding step of bonding the lining glove, the membrane glove, and the outshell glove by heating the outshell glove with the membrane glove inserted through the membrane glove inserting step.

In producing an elastic glove made of rubber or resin and having an interior surface flocked with piles through a step for depositing the piles on a film of a latex composition formed on a surface of a mold conformal to a three-dimensional shape of the elastic glove, a water repellent/hydrophilic pile mixture containing water repellent piles in a proportion of 10 to 80 mass % is used as the piles to uniformize a pile embedded state in a rubber or resin film defining the interior surface over the substantially entire surface of the elastic glove.
