Abstract: A thermoplastic fabric for use as a support fabric in interfacing, underlining, and applique carries a persistent electrostatic charge that causes the fabrics in contact therewith to cling thereto in a nonslip relationship. This facilitates sewing of the layers together. The preferred support fabric is a nonwoven fabric such as meltblown and spunbonded fabrics.

The interface is provided as a cured sheet of a curable material formulated as a blend of a curable silicone binder, and a particulate alumina, i.e., aluminum oxide (Al.sub.2 O.sub.3), filler. The interface is observed to exhibit a thermal conductivity of at least about 0.8 W/m-K and a wet dielectric breakdown strength of at least about 475 Vac/mil.
Abstract: Abrasion resistant laminates which are aesthetically pleasing, water-resistant/water-repellant, and flexible are formed by laminating a wear-resistant durable multi-layer top assembly to a base layer formed from an inexpensive, water resistant, polymeric substrate. The durable multi-layer wear-resistant top layer assembly comprises a wear resistant upper layer, a decorative layer, and a core layer. The polymeric base layer comprises a water resistant substrate which is positioned beneath the top layer assembly and is laminated thereto with a water resistant adhesive. This abrasion resistant laminate could be applicable in a variety of situations wherever a decorative and/or abrasion resistant product could be used and would be particularly useful in the floor covering industry.

Abstract: Color images with high fixation comparable to that of silver salt photographic images are formed on printing papers, using aqueous ink compositions by ink jet recording. Color images thus formed have high saturation and high resolution. An intercalated compound capable of fixing water-soluble dyes to a printing paper due to the intercalation based on ion-exchanging between them is incorporated into the dye-receiving layer 2 of the paper, on which color images are formed by ink jet recording using an aqueous ink composition containing a water-soluble dye. The content of the intercalated compound in the layer 2 is from 10 to 90% by weight. As the intercalated compound, montmorillonoids are preferred when water-soluble cationic dyes are used while hydrotalcite-group minerals are preferred when water-soluble anionic dyes are used.
Abstract: A polymeric material in a grid configuration comprising an integral uniplanar or substantially uniplanar oriented grid formed from orientable thermoplastic polyester, polyamide or polyurethane elastomer.

Abstract: A composition for the promotion of adhesion between a rubber formulation and a textile substrate is provided. The inventive composition comprises either a mixture of specific amine functional silanes and organo-functional silanes having reactive groups or groups with an affinity for rubber. The inventive method entails the use of the inventive composition or a silane compound having both an amine moiety and a reactive group having an affinity for rubber formulations, particularly an unsaturated carbon-carbon bond. The composition may be utilized to adhere any standard reinforcement-type textile, such as polyester or polyamide, to a standard rubber composition, such as SBR, NBR, or EPDM. A method for adhering textiles to rubber formulations is also provided involving a pre-dip, -spray, -coat, and the like, of the inventive composition on a reinforcement-type textile surface followed by the contacting of the rubber formulation.
