Low density attached polyurethane foams made using a combination of frothing and blowing methods
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.
TEXTILE HEAT-, FIRE- AND/OR SMOKE-PROOF MATERIAL
A textile heat-, fire- and/or smoke-proof material, comprising a flat, textile substrate which is coated with a polymer composition. The polymer composition containing a cross-linked silicone resin and metal pigments. The invention also relates to a method for producing a textile heat-, fire- and/or smoke-proof material, and to the use of a textile structure as a heat protector in a vehicle(s) and as fire and heat protection in a building(s).
AQUEOUS COATING-FILM-FORMING COMPOSITION FOR FORMING LUBRICATING COATING FILM, AND AIR BAG USING SAID COMPOSITION
An aqueous coating film-forming composition is provided that can be coated uniformly on a silicone rubber surface without causing repelling or coating failure even when applied to the silicone rubber surface at a film thickness of 30 μm or less, and forms an antifriction dry coating film that reduces friction and/or blocking of the substrate surface on the surface. The composition comprises (A) a solid lubricant, (B) a thickener, and (C) a silicone binder in the form of an oil-in-water silicone emulsion comprising (c1) an ionic emulsifier and (c2) a polyoxyethylene-polyoxypropylene copolymerized nonionic emulsifier. Water content is removed from the composition to form an antifriction dry coating film comprising 40 to 80 mass % of component (A), 0.50 to 10 mass % of component (B), 0.60 to 5 mass % of component (c2), and 5 to 49.5 mass % of component (C) (solid fraction). Applications thereof are also provided, e.g. airbag coatings.
WATER-REPELLENT RESIN, WATER-REPELLENT FABRIC, AND FABRICATING METHOD THEREOF
A water-repellent fabric includes a base cloth and a water-repellent resin. The water-repellent resin is disposed on the base cloth, in which a method of fabricating the water-repellent resin includes the following steps. A first thermal process is performed to mix a polyol, a cross-linking agent, and a choline to form a first mixture, in which a reaction temperature of the first thermal process is between 90° C. and 120° C. A second thermal process is performed to mix the first mixture and a water repellent to form the water-repellent resin, in which the water repellent includes a hydroxyl group, an amino group, or combinations thereof, and a reaction temperature of the second thermal process is between 120° C. and 150° C.

Articles and Components with UV Radiation Curable Elastomeric Materials and Methods of Making the Same
A method of manufacturing an article that includes providing an element formed of an elastomeric material or composite; placing the surface of the element in contact with a substrate; and affixing the element to the substrate. The element includes an uncured, partially cured, or fully cured UV radiation curable elastomeric material and optionally one or more regions of an adhesive material. The element is affixed to the substrate while the surface of the element is in contact with a surface of the substrate by increasing a temperature of at least a portion of the element, applying pressure to at least a portion of the element, or exposing the uncured or partially cured UV radiation curable material to UV radiation in an amount and for a duration of time that is sufficient to partially cure the uncured material or to fully cure the partially cured material.
ARTIFICIAL LEATHER PRODUCT AND PROCESS FOR PRODUCING SAME
This invention relates to an artificial leather having a laminated structure and a process for producing such product. The artificial leather comprises a non-woven matt formed from bast fibres, more particularly fibres obtained from hemp plants. The fibres in the non-woven matt are impregnated with a polymer, such as a polyester or polyurethane. The artificial leather includes the non-woven matt as a discrete bottom layer in a laminated structure also comprising a discrete intermediate layer of a binder material and a discrete top layer of a polymer coating material.
COATED BARRIER FABRIC FOR A REUSABLE MEDICAL PRODUCT
A coated barrier fabric for use in a reusable medical product (e.g., surgical gown, surgical drape, etc.) is provided and has two woven or knitted plies. Each of the two plies are coated on one side with a non-fluorine containing polymer and retain similar comfort and feel of uncoated woven or knitted fabrics. The coated sides of the plies face each other (i.e., inwardly) in the interior of the barrier fabric. Because of the orientation of the plies, the coated sides of the plies can come into direct contact with and move freely against each other within the interior of the barrier fabric. The coating on each of the plies is protected from exterior and environmental factors, including repeated institutional laundering/autoclave cycles, that could abrade and degrade the coating. Thus, the useful life of the reusable medical product including the barrier fabric is extended.
