A foamed, opacifying element is prepared to have a light-blocking value (LBV) of at least 4. A method is carried out in a specific order with a unique series of steps including: providing a unique foamable aqueous composition; aerating that foamable aqueous composition to a foam density of at least 0.1-0.5 g/cm.sup.3; disposing the foamed aqueous composition onto a surface of a porous substrate; drying the foamed aqueous composition without substantial curing of the binder material therein, to provide a dry foamed composition on the surface, without substantial curing; densifying the dry foamed composition to provide a dry opacifying layer in a foamed, opacifying element; and curing the dry opacifying layer in the foamed, opacifying element.

A seat molded article and a method of preparing a seat molded article are disclosed. The seat molded article includes: an upper pad formed of polyurethane foam having a thickness in a range of 25 to 50 mm; and an elastic fabric disposed under the upper pad, wherein, in the elastic fabric, a difference in tensile elongation between warp and weft directions is 5.0% or less, and a tensile elongation measured under a load of 20 kgf is in a range of 20 to 40% in the warp and weft directions.

A method is designed to prepare foamed, opacifying elements each having a target light blocking value (LBV.sub.T) of at least 3, using a textile fabric substrate with a light blocking value (LBV.sub.S). The LBV.sub.T-S difference is calculated; a foamable aqueous composition is chosen; a dry coating weight for the foamable aqueous composition (when foamed) is determined to form a single dry opacifying layer that is foamed, dried, and densified to provide a dry thickness at least 20% less than the original dry thickness. The single dry opacifying layer a has light blocking value that is equal to LBV.sub.T-S, 15%. The desired foamable aqueous composition can be chosen from a set of similar compositions to achieve the desired LBV.sub.T with the noted textile fabric substrate using suitable mathematical formula relating dry coating weight to light blocking value and a suitable data processor.

A process is disclosed for the preparation of multilayered composite materials comprising, as components: (A) a backing material, (B) optionally at least one tie layer and (C) a polymer layer,

A silicone/polyurethane synthetic leather topcoat composition is disclosed. The silicone/polyurethane synthetic leather topcoat composition is a hydrosilylation curable silicone elastomer composition which provides good adhesion to polyurethane and is used to provide a topcoat for a silicone/polyurethane composite synthetic leather material. The topcoat is the cured product of the composition. Also disclosed are methods of making the topcoat and the silicone/polyurethane composite synthetic leather material as well as uses of the silicone/polyurethane composite synthetic leather material.

A host of new silk material formats are disclosed, all prepared from an initial liquid composition including both silk fibroin and xanthan gum. In some cases, particularly preferred material properties are achieved by the addition of glycerol. These various formats include liquids, whipped silk creams, silk meringues, and compressed/heat-compressed meringues. Among the useful end-uses for these materials is a silk leather, which mimics the feel of conventional leather. Other uses include thermal insulation, absorption/gas sensing, biological scaffolding, and the like. A material that has material properties unexpectedly similar to mycelium is also disclosed.

The invention relates to flame-retardant foam coatings for textile sheet products, wherein the coatings include plate-like expandable graphite which has a reduced salt content and a particle distribution with a proportion of >80 percent by weight having a diameter of at least 0.2 mm, and/or a minimum proportion of 70% having a mesh size of >50 mesh (0.3 mm), at least one binder and at least one foam stabilizer, and also processes for the production thereof, the use thereof for producing textile sheet products and also textile sheet products having such flame-retardant foam coatings.

A foam printing method includes producing and programming a design being formed on a substrate using a computer program, forming the design on a plate, removing a part of a surface of the substrate along the design, combining the substrate and the plate to coincide a designed portion formed on the plate and a removed portion of the substrate, printing a foam constituting the design on the plate combined with the substrate, separating the plate from the substrate and drying the substrate, and applying a pressure to the foam passing the plate to be set on the substrate to be foamed. The foam passes the designed portion of the plate to be set on the removed portion of the substrate during the printing.
