Additional layers of material, including additional layers including filament and/or fabric elements, e.g., of the types described above, may be included in the upper.

Arc flash resistant multilayered material having low thickness

A multi-layered material with low thickness is provided, having properties of thermal and electric insulation, flame retardant capacity and high mechanical strength, useful for the manufacture of personal protective equipment and more in general of work items for the protection against arc flash effects. The material provides a high grade of protection against arc flash with good flexibility and comfort for the wearer, who is thus protected without being hindered in movements.

20230025328 · 2023-01-26 ·

A moisture-curable polyurethane hot melt adhesive composition having good oleic acid resistance, especially when exposed to 100% pure oleic acid under aging condition of 65° C. and 90% relative humidity, wherein the adhesive composition comprises, consists essentially of or consists of a moisture-curable polyurethane prepolymer, the prepolymer being a reaction product of at least one amorphous polyester polyol containing an aromatic group and at least one polyisocyanate, preferably at least one polyisocyanate containing an aromatic group, wherein the aromatic group is comprised in the polyurethane prepolymer in a content of no less than 23 wt. %, preferably no less than 25 wt. %, more preferably no less than 30 wt. %.

A NEW MULTI-LAYER INTERLINING AND THE PRODUCTION PROCESS THEREOF

Disclosed is a new multi-layer nonwoven interlining and the production process thereof. The process allows a multi-layer nonwoven interlining to be obtained simultaneously with a single process on a single production line. The process includes a fiber opening step, a fiber feeding step, a carding step, a levelling step of the additional layer by the thermal treatment, and a point bonding step of the carded web and additional layer. As a result of the process, a structure is obtained where the carded web is point-bonded onto the additional layer.

Method of making a multilayered elastomeric article

Elastomeric articles, such as gloves, made from more than one layer, are provided. The gloves can include a first (grip side) layer in which a first colorant is compounded or integrated and a second (donning side) layer in which a second colorant is compounded or integrated. Alternatively, the gloves can include a translucent first layer and a second layer in which a colorant is compounded or integrated. Either arrangement can enable a breach of the first layer to be more easily detected, either due to the high level of contrast between the first layer and the second when a first colorant and a second colorant are utilized, or due to the translucence of the first layer as compared to the donning side layer, where the intensity of the second layer is increased upon a breach of the translucent first layer.

Fluid-filled chamber for an article of footwear
11700914 · 2023-07-18 · ·

A fluid-filled chamber is provided and includes a first barrier layer, a second barrier layer, a foam structure, and a tensile member. The second barrier layer is secured to the first barrier layer to define an interior void between the first barrier layer and the second barrier layer. The interior void contains a predetermined volume of fluid. The foam structure and the tensile member are disposed within the interior void, whereby the tensile member includes a plurality of fibers extending in a first direction between the first barrier layer and the second barrier layer.

Footwear sole structure having a fluid-filled chamber including a tensile member

A footwear sole structure having a fluid-filled chamber including a tensile member is provided. The fluid-filled chamber includes a first barrier sheet, a second barrier sheet and the tensile member. The first barrier sheet is formed from a first thermoplastic material. The second barrier sheet is attached to the first barrier sheet and is formed from a second thermoplastic material. The first barrier sheet and the second barrier sheet cooperate to define an internal cavity. The tensile member is disposed within the internal cavity and is formed from a third thermoplastic material. A first weld attaches the first barrier sheet, the second barrier sheet, and the tensile member together by melding the first thermoplastic material of the first barrier sheet, the second thermoplastic material of second barrier sheet, and the third thermoplastic material of the tensile member.

Variable Emissivity Surfaces
20230017078 · 2023-01-19 ·

This invention relates to devices integrally comprising fibres that have emissivities, particularly of infrared radiation, that can be controllably varied. The active emissive surface comprises graphene layers with intercalated ions.

Method of forming an article of apparel

An article of apparel includes a composite material. The composite material includes a pliable first layer and a resilient second layer, where the first and second layers are secured to each other via a patterned strand network. In forming the composite material, the second layer is stretched and maintained under tension while the first layer is secured to the second layer via the patterned strand network. The tension on the second layer is then released, resulting in contraction of the second layer in relation to the first layer and an outward buckling or protrusion of the first layer in relation to the second layer to form protruding cells along the composite material that are bounded by portions of the patterned strand network. The patterned strand network can be formed using embroidery with one or more auxetic patterns in the stitching.

DOT BONDING SHOE INSOLE USING ADHESIVE RESIN MIXED WITH HYDROPHOBIC NANO- SILICA AND MANUFACTURING THEREOF
20230218041 · 2023-07-13 ·

A present invention related to a method for manufacturing a dot bonding shoe insole using an adhesive resin containing hydrophobic nano-silica, including: melting adhesive resin made of any one selected from thermoplastic polyurethane (TPU) or ethylene vinyl acetate (EVA) containing hydrophobic nano-silica in the range of 0.2 to 5 phr and applying to the surface of the transfer roller in which the intaglio dot pattern is formed in a mesh shape in the shape of the shoe insole;

removing the adhesive resin applied other area than the intaglio dot pattern of the surface of the transfer roller;
transferring the adhesive resin applied to the intaglio dot pattern of the surface of the transfer roller to either one of the foam or the fabric;
bonding the foam and the fabric by compressing; and
cutting a shoe insole shape in a package in which the foam and the fabric are bonded.
