  • Patent number: 8623252
    Abstract: A process of manufacturing a fibrous article includes submerging a fiber substrate in a bath of first thermoplastic resin to impregnate the fiber substrate with the first thermoplastic resin; heating the fiber substrate until the fiber substrate becomes a thick continuous fiber substrate; cutting the thick continuous fiber substrate into units; stacking the fiber substrate units; pressing and heating the stacked fibrous structure units until a stacked fibrous structure is formed; heating a mold; conveying the stacked fibrous structure to the mold to melt; cooling the mold to shape the molten fibrous structure into a half-finished article; removing the half-finished article out of the mold; eliminating burrs and sharp edges of the half-finished article; conveying the half-finished article to the mold; and uniformly applying a molten second thermoplastic resin on an inner surface of the half-finished article by injection molding to produce the finished fibrous article.

  • Patent number: 8303880
    Abstract: A process of manufacturing a plastic product includes selecting natural or synthetic fiber as a material; adhering a thermoplastic resin onto surfaces of the material to form a thin film thereon by soaking or heating; heating the thin film; forming two releasable films on upper and lower surfaces of the thin film respectively; cutting the thin film into thin film units; heating and pressing the thin film units to form cured thin film units; applying one of the cured thin film units onto an inner surface of a first mold; further heating and pressing the cured thin film unit to form a thin film structure; placing the thin film structure inside a second mold; and injecting a thermoplastic material into the second mold to adhere onto an outer surface of the thin film structure to produce the finished plastic product.

  • Publication number: 20110104971
    Abstract: A fibrous article having a fabric-like surface and process of manufacturing same are provided. The fibrous article includes an outer fabric substrate; an intermediate fiber substrate; and an inner thermoplastic resin layer. A first thermoplastic resin is formed between the fabric substrate and the fiber substrate. The first thermoplastic resin is further formed between the fiber substrate and the thermoplastic resin layer. The thermoplastic resin layer is formed by injection molding by causing a second thermoplastic resin to react with the first thermoplastic resin. A person may have the feeling of touching fabric when touches the fibrous article.

  • Publication number: 20110104497
    Abstract: A reinforced fiber blank and process of manufacturing same are provided. The process includes passing a continuous fiber sheet through a bath of thermoplastic resin so that the thermoplastic resin permeates the continuous fiber sheet to form a continuous fiber substrate permeated with the thermoplastic resin; stacking at least one fiber substrate and at least one thermoplastic resin layer to form a stack; and heating and pressing the stack at a temperature between about 60° C. and 150° C. to produce the finished reinforced fiber blank.

  • Publication number: 20070002514
    Abstract: A liquid crystal display (LCD) capable of negative ion generation is disclosed. The LCD utilizes existing power inverter to generate negative ions by means of corona discharge or silent discharge, which offers an extra function without altering the structural design of existing power inverter while saving the space required for generation of negative ions. In addition, the LCD excites negative ions with little power without affecting its normal operation. Using the LCD disclosed in this invention not only neutralizes the adverse effect of positive ions on human body, the negative ions produced by the display can help purify blood, activate cells, boost immunity, regulate autonomous nerves and remove harmful substances, suspended particles, and odors in air, and kill germs. It benefits the health of people who use computer constantly.
