  • Publication number: 20050181190
    Abstract: A method for making a macromolecular laminate is disclosed. Firstly, polyurethane resin with solid content higher than 50% is mixed with additives in order to form polyurethane resin compound that is liquid at the normal temperature. Then, the polyurethane resin compound is coated on releasing paper and dried. Then, the releasing paper is removed in order to make a substrate. Then, the substrate is put in a physical vapor deposition system in which metal is used as a target. Finally, the metal is sputtered to the substrate in order to form a metallic film, thus making a macromolecular laminate.

  • Publication number: 20050100710
    Abstract: Flame-proof environmentally friendly artificial leather includes a substrate, an adhesive layer, an intermediate layer and a surface layer. The artificial leather is characterized in including the intermediate layer made of a high solid-content polyurethane resin compound added with a chlorine-free flame-proof agent. The high solid-content polyurethane resin compound is made through mixing the chlorine-free flame-proof agent, polyurethane resin with a solid-content higher than 50% and a curing agent. Moreover, a process is disclosed for making the flame-proof environmentally friendly artificial leather.

  • Publication number: 20040191412
    Abstract: A process is disclosed for making ultra micro fiber artificial leather. Firstly, a substrate is made from ultra micro fibers of sea-island type and a reinforcement layer via needle punch or water jet. The ultra micro fibers all include a sea component and island components. Then, the sea component of each of the ultra micro fibers is dissolved. Finally, the substrate is submerged in elastomeric resin.

  • Patent number: 6737004
    Abstract: A microfiber substrate of improved carding ability and its manufacturing method, and more particularly a micro-fiber spun by conjugated melting of crystallization difference of high crystallization polymer and low crystallization polyester, drawn to form an unsplit microfiber staple having a layer of thin film in its surrounding, the microfiber staple which is still kept in unsplitting state during opening, carding and lapping treatment, will be split just at the layer of thin layer of its surrounding of the microfiber staple by spunlace to completely split from the microfiber, knitted to form water-jet punch web, then subject to hot water to shrink to densification. The microfiber nonwoven web excellent in the wiping effect, cleaning effect and microfiber artificial leather excellent in the hand feeling and fluff compaction without environment pollution is enabled to offer the artificial leather more cheaply and easily finished.

  • Patent number: 6592700
    Abstract: The present invention relates to a method for preparing retro-reflective sheet with high abrasion resistance produced by initially coating the first coating layer one component type polyurethane (hereinafter refer to PU) resin mixed with reflective particles on the pattern releasing paper with embossed grain, and after drying, further coating the second layer two component type PU resin adhesive agent containing colorant, then drying; above this, coating a kind of paste; finally, adhering substrate; after pre-drying and curing, divesting releasing paper, using solvent to solve the part of PU resin leaving reflective particles exposed and hardened. The material produced characterized in high abrasion resistance and using soft material as substrate. Use of the retro-reflective material produced by the invention is valuable for commercial fields like coat, vest, shoes, cap, poster, and the like.
