20200352266 · 2020-11-12 ·

Systems and methods for creating a grip surface (104) of a protectant glove (100). The method may comprise dipping a glove mold into a coagulant material (206); dipping the glove mold into a nitrile coating formulation to form an outer surface of the glove (208), wherein a biodegradable material is distributed throughout the nitrile coating formulation; vulcanizing at least the outer surface of the glove to form a protectant outer surface (212); washing at least the outer surface of the glove with an enzyme solution; decomposing, by the enzyme solution, the biodegradable material that is distributed throughout the outer surface of the glove, thereby forming a grip surface of the glove comprising an open-cell structure within the outer surface (216); and drying the glove to form a final glove comprising the grip surface (218).

Polymer microwedges and methods of manufacturing same

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.

20200253306 · 2020-08-13 ·

A layered, laminated glove includes an outer layer, a membrane formed from a liquid-resistant, air permeable material positioned on an inner surface of the outer layer and a liner formed from a moisture absorbing material. The liner is positioned on an inner surface of the membrane. The outer layer, membrane and liner are laminated to form a single glove. The glove includes a plurality of fingertip portions in which the outer layer, membrane and liner are substantially fully laminated throughout. The glove may include a 3D pattern formed in one or more layers of the laminate. The glove may include an enlarged knuckle section. A hand mold and system for making the gloves and a method are also disclosed.

LAMINATE PRODUCTION METHOD

A method for producing a laminate including a substrate and a rubber layer, the rubber layer having a thickness of 200 m or more from the surface of the substrate, the method including contacting the substrate in a heated state with a polymer latex having a viscosity of 2,000 to 100,000 mPa.Math.s at 25 C. to thereby coagulate the polymer in contact therewith to form the rubber layer.

WATER-BASED HYDROGEL BLEND COATING AND METHOD OF APPLICATION TO ELASTOMERIC ARTICLES

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.
