Abstract: A method of manufacturing a synthetic leather formed with a pattern includes a mixing step (A) in which at least a first material and a second material are properly mixed in proportion into a mixture; a first coating step (B) in which the mixture is coated on a substrate to form a blocking layer; a printing step (C) in which a determined pattern is printed on the surface of blocking layer to form a pattern layer; and a second coating step (D) in which at least the mixture is coated on the pattern layer to form a surface layer, thereby a product being finished. Thus, the pattern layer may be sandwiched between the blocking layer and the surface layer, which prevents the pattern layer contacting the substrate or outside from fading in color and shedding off and prevents the child from eating, by accident, the fall-off pattern layer.

Abstract: A method of manufacturing an adhesive material that can be printed and repeatedly stuck and torn including a first mixing step in which a first material of isocyanate polymer containing NCO is mixed with a second material of hydroxy compound containing OH into a first mixture; a first coating step in which the first mixture is coated on a substrate to form an adhesive layer; a second mixing step in which at least the first material, the second material, and a fiber material are mixed into a second mixture, and a second coating step in which the second mixture is coated on the adhesive layer to form a printing layer, a finished product being formed. A pattern or character can be printed on the printing layer, and the printing layer is pasted on a determined site for repeated paste and tear. The product is preferably resilient and not easily damaged.

Abstract: A method for forming patterns on face membrane by air-drawing force when vacuum. A foamed polyurethane (PU) is injected on the surface of substratum cloth to form a face membrane. The face membrane is heated at a preset temperature by a preheating box to be continuously maintained in a softened condition before it is not thoroughly hardened. An airproof release film is attached on one side of the substratum cloth opposite to the face membrane. A roller having functions of vacuum and cooling has its superficial patterns being pressed and printed on the heated face membrane by the air-drawing force when vacuum.

Abstract: A flexible keyboard includes a first layer combined with a second layer. The first layer has a first base cloth, a hot melt film spread on the first base cloth, and at least a first metallic sheet fixed on the hot melt film. The first metallic sheet is connected with a conducting line. The second layer has a second base cloth, a hot melt film spread on the second base cloth, and at least a second metallic sheet fixed on the hot melt film to correspond to the first metallic sheet. The second metallic sheet is connected with a conducting line. A foamed layer is sandwiched between the first layer and the second layer, with at least a gap formed for being pressed. So, if the invention is installed in clothes, a user can just press on the clothes corresponding to the gaps to operate an electronic appliance.

Abstract: A method for directly forming patterns on face membrane by vacuum absorption is to have foamed polyurethane (PU) injected on the surface of substratum cloth to form a face membrane. Then, the face membrane is heated at a preset temperature by a preheating box to be continuously kept in a softened condition before it is not thoroughly hardened. Subsequently, a roller having functions of vacuum absorption and cooling has its superficial patterns quickly pressed and absorbed on the heated face membrane by vacuum absorbing force, and simultaneously the patterns on the face membrane is quickly cooled off and fixed in shape by the roller, thus shortening a producing process, saving factory equipment, conforming to environmental conservation and economizing energy source.

Abstract: A manufacturing process for a three-dimensional patterned leather or textile is to employ a three-dimensional releasing paper transferred to a raw material mixing device to let its patterned surface filled with a PU resin with a certain thickness. Then, a flat releasing paper is attached on a surface of the PU resin opposite to the three-dimensional releasing paper, forming a semi-product that is further finished by a finishing device to become a three-dimensional patterned textile via combining with a base textile or a three-dimensional patterned leather by means of a finishing mold. No solvent is utilized through the whole process, achieving a purpose of environmental protection and public health.

Abstract: A method for manufacturing resin films includes steps of mixing PU resin and hydroxyl compound to become a first-kind first-phase mixture, and of mixing a pigment with a foaming agent to become a second-kind mixture, of injecting the first-kind mixture into a kneading device to get mixed and kneaded to become a first-kind second-phase mixture, of sending the first-kind second-phase mixture into a second kneading device to get a first-kind third-phase mixture, and the second-kind mixture and the first-kind third-phase mixture both sent into a conveyer to get a third-kind mixture, and the final step is to send the third-kind mixture into a coating device for coating the third-kind mixture on a substrate cloth to get a resin film of an original color and fresh brilliance.

Abstract: A polyurethane resin coating device includes a material mixing unit for mixing materials to have them reacted to form polyurethane resin liquid mixture. Subsequently, the polyurethane resin liquid mixture flows downward to a pressuring and sending unit to be mixed and reacted again by the helical rods rotating in the pressuring and sending unit and then pressured and conveyed to a gear pump. Afterward, the polyurethane resin liquid mixture is controlled by the rotating speed of the gears in the gear pump and steadily conveyed onto a coating wheel. A gap adjustable in size is formed between the wheel surface of the coating wheel and the outlet of the gear pump, able to carry out coating steadily and evenly.
