Method for making a coated fabric
A method for making a coated fabric includes the steps of: applying a coating solution of a resin in an organic solvent to a roller-conveyed non-stretchable and releasable substrate web to form a coating layer; laminating a roller-conveyed base fabric to the coating layer to form a laminate; guiding the laminate to pass through at least one tank containing water to immerse the laminate in water such that the coating layer is solidified and the organic solvent contained in the coating layer is replaced by water; and removing water from the coating layer by drying to leave micropores in the coating layer.
METHOD FOR PRODUCING FABRIC SUBSTRATE MOLDED PRODUCT COATED WITH SILICONE RUBBER, AND ARTIFICIAL LEATHER-LIKE SHEET MOLDED PRODUCT
Provided is a method for producing a fabric substrate molded product coated with silicone rubber, wherein the adherence of dust, flashes during molding, and foreign matter is prevented because the obtained cured coating film has surface lubricity, and breaking and cracking do not occur when the fabric substrate is deformed because the obtained cured coating film has elongation. This method for producing a fabric substrate molded product coated with silicone rubber, in which method the surface of the fabric substrate is coated with a first coating layer and a second coating layer by forming a first coating layer, which comprises a cured product of a liquid silicone rubber composition, on at least one surface of the fabric substrate, and then forming a second coating layer, which comprises a cured product of a silicone rubber composition, on the outer surface of the first coating layer, is characterized in that the first coating layer is a cured product of a liquid silicone rubber composition that contains an adhesiveness-conferring component, and the second coating layer is a cured product of a silicone rubber composition that contains a silicone resin.
Imitation leather and method for producing same
An imitation leather including a three-dimensional textile supporting material and a PVC-based covering that is applied to one side of the supporting material and includes three successively applied layers. The first layer of which is applied directly to the supporting material without an adhesion-promoting glue layer, the second layer of which is embodied as an intermediate layer and applied directly to the first layer and the third layer of which serves as a top layer and is applied directly to the second layer. This invention also discloses a method for producing such an imitation leather and an interior component of a motor vehicle having a visible surface that is composed of such an imitation leather.
Method for producing an artificial leather with improved flexing endurance properties
