Abstract: A resin-coated non-woven fabric is provide that may be welded through a high-frequency welder and may be remedied in hardness, and further may have a clear embossed pattern. A resin-coated non-woven fabric of the present invention comprises: a filament non-woven fabric that is of a thermocompression-bondable type, is made of a polyethylene terephthalate and has a weight of 50 to 150 g/m2; and a resin coat layer positioned over one surface of the filament non-woven fabric and having a coating amount of 40 to 150 g/m2 after dried; wherein the resin coat layer contains 10 to 45% by mass of a vinyl chloride unit and 30 to 55% by mass of a (meth)acrylic acid ester unit, and further a surface of the resin coat layer has an embossed pattern.

Abstract: A method for manufacturing polishing cloths of the class to be used with abrasive powders on a lapping machine is disclosed. The method comprises the steps of impregnating a nonwoven fabric sheet with a solution of polyurethane elastomer, wet-coagulating the impregnated sheet, and heating the resulting microporous composite sheet at a temperature higher than the softening point of the polyurethane elastomer under an essentially uncompressed condition.

Abstract: This invention relates to a method of producing a moisture-permeable artificial leather comprising transferring a water-soluble inorganic salt-containing polyurethane layer onto a base fabric and washing the polyurethane layer with water to extract out said water-soluble inorganic salt. A feature of the invention is that the inorganic salt used has a particle diameter range such that at least 90% thereof is not larger than 30 microns.

Abstract: A polyurethane top coating and a porous, polyurethane interposing layer are formed on a release carrier sheet. Split leather hide is bonded onto the porous layer with a compatible adhesive and the release carrier sheet is stripped from the top coat. The resultant laminate has the appearance and other properties of top-grain leather. The interposing porous layer functions as a cushion and prevents uneven deformation of top coat when the laminate is folded or stretched.

Abstract: Synthetic suede leather is produced by casting a mixture containing polyurethane elastomer and a solvent therefor between two sheets of a substrate fabric, immersing the resulting structure in a liquid which is a nonsolvent for polyurethane elastomer but miscible with said solvent, splitting said structure into two sheets at middle of the cast layer before it is fully gelled, and re-immersing the resultant sheets in said nonsolvent to allow complete gelation of said mixture.

Abstract: A lustrous top surface is imparted to artificial leather having a substrate, a flexible thermoplastic layer and a top coating essentially consisting of a thermoplastic resin by contacting the top coating with a mirror-like surface for a short period of time while applying heat to the intersurface therebetween at a temperature of at least about 10.degree. C. but not more than 40.degree. C. lower than the softening point of the resin in the top coating.

Abstract: Artificial leather is produced by applying a dope comprising urethane prepolymers containing terminal isocyanate groups, an amine catalyst and a foam stabilizer onto a releasing carrier sheet, exposing the resulting coating layer to a moisture-containing gas under controlled conditions, laminating the coating layer onto a backing material and stripping off the releasing carrier sheet. The resulting artificial leather has a cellular structure of polyurethane microfoam in adhesion with the backing material and an adhesion strength of 100 to 10,000 g/cm of width.

Abstract: A synthetic resin composition which comprises 20 to 50 parts by weight of olefinic resins, 10 to 40 parts by weight of vinyl chloride resins, and 70 to 10 parts by weight of alumina trihydrate having a gibbsite crystal structure whose average particle size is 30 microns at most.
