DIMENSIONAL ENHANCEMENT OF ARTIFICIAL LEATHER POLYURETHANE COMPOSITE MATERIAL

A composite material formed by combining a polyurethane material with an unclickable foam layer and a scrim layer through roll and flat form technology. The composite material is embossed to form pillowlike chambers or cells delineated by a network of emboss pattern lines formed by the bonding between these layers.

FOAM NODES FOR CREATING STAND OFF ON APPAREL ITEMS
20170273377 · 2017-09-28 ·

Aspects herein relate to apparel items and apparel systems that utilize applied or printed foam nodes to provide, among other things, stand-off between an apparel item and a wearer's skin surface. One or more of the foam nodes, or areas of the textile surrounding the foam nodes, may be perforated to provide a fluid communication path between an inner-facing surface and an outer-facing surface of the apparel item. The communication path may be used to facilitate air exchange between the external environment and the wearer's body and/or to provide an exit path for moisture vapor generated by the wearer.

Low density attached polyurethane foams made using a combination of frothing and blowing methods
09765477 · 2017-09-19 · ·

Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.

AQUEOUS, POLYVINYL ALCOHOL STABILIZED VINYL ACETATE-ETHYLENE-COPOLYMER DISPERSION HAVING HIGH FILLER COMPATIBILITY FOR CARPET COATING COMPOSITIONS

The invention relates to an aqueous vinyl acetate-ethylene-copolymer dispersion for carpet coating compositions, which is obtained by means of radical-initiated emulsion polymerization, in an aqueous medium, of vinyl acetate and ethylene and optionally additional ethylenically unsaturated comonomers, characterized in that, for stabilization of the dispersion, 5 to 10 wt %, based on the total weight of the comonomers, of one or a plurality of partially saponified and low-molecular polyvinyl alcohols having a hydrolysis degree of 80 to 95 mol % and a Höppler viscosity, in 4% aqueous solution, of 1 to 5 mPas (method according to Höppler at 20° C., DIN 53015) are contained.

USE OF TWO-TAIL LONG-CHAIN ANIONIC SURFACTANTS IN AQUEOUS POLYURETHANE DISPERSIONS

METHOD FOR PREPARING WPU SYNTHETIC LEATHER FOAMING LAYERS BASED ON PICKERING FOAM TEMPLATE METHOD
20220185984 · 2022-06-16 ·

The disclosure provides a new method for preparing a WPU synthetic leather foaming layer based on a Pickering foam template method. The key of the method is to use the soft waterborne polyurethane as raw materials, add waterborne crosslinking agent and hydrophobic inorganic solid particles as Pickering waterborne foam stabilizers to obtain Pickering waterborne foam slurry of polyurethane latex particles through high-speed emulsification; and dry the slurry to obtain the waterborne polyurethane foam layer. The preparation process does not use any organic solvents, is clean and environmentally-friendly, and is simple to operate, making it easier to realize industrialized production. In addition, the Pickering foam has strong interface stability, which effectively solves the problem of difficult adjustment of the pore size caused by the accumulation and collapse of bubbles during the drying process of the mechanical foaming method, and the prepared synthetic leather foam layer has good hygienic properties.
