Provided is a method for manufacturing a molded plastic products having copper-based compound particulates. The method includes the steps of: reacting copper sulfate with sulfuric salt, at a molar ratio of 1:1 in an aqueous solution at a temperature of 1080 C., thereby synthesizing copper sulfide particulates; forming a sheet comprising the copper sulfide particulates dispersed in a thermoplastic resin.

Provided is a foley catheter and a method of manufacturing the same, it is characterized in that the foley catheter comprises a catheter body made of a material which a carbon nanotube polymer (CNT Polymer) bonded a carbon nanotube and zinc oxide (ZnO) is combined with a silicon; and a foley for catheter that are made of a material which a carbon nanotube polymer (CNT Polymer) bonded a carbon nanotube and zinc oxide (ZnO) is combined with a silicon, and are bonded to the catheter body so as to be inflated by a fluid introduced from the outside; wherein the mixing ratio of the carbon nanotube polymer of the said foley for catheter is higher than that of the carbon nanotube polymer of the said catheter body.

A method for producing fibers with improved color and anti-microbial properties is described. One embodiment includes a method for generating a halogen stable antimicrobial synthetic fiber, the method comprising creating a mixture that includes a polymer, an anti-microbial agent, and a non-halogen pigment, and extruding the mixture to form an anti-microbial synthetic fiber.

A multilayered polymer composite film includes a water-soluble polymer matrix and a plurality of fibers embedded within the water soluble polymer matrix. The fibers include a water insoluble polymer material and at least one of a non-polymeric hydrophobic therapeutic agent or a non-polymeric hydrophobic cosmetic agent incorporated in the water insoluble polymer material. The fibers have a rectangular cross-section, and extend the entire length of the multilayered polymer composite film.

A method for manufacturing a synthetic resin scouring pad includes hot extruding a polymer by thermally melting a synthetic resin, along a T die having a straight extrusion port, to form a full width film sheet; cold-curing the film sheet by impregnating and quenching the extruded full width film sheet with cooling water of a cooling bath; forming flat film filaments by passing the full width film sheet lengthwise through a cutting part in which cutting blades are arranged at a predetermined width so as to dividingly-cut the full width film sheet into a predetermined width; passing the flat film filaments in the longitudinal direction through a coiling forming part to plastic-deform the flat film filaments into coil-shaped film filaments; and inputting the coil-shaped film filaments into an annular winding part so that the film filaments are wound in an annular shape to form a synthetic resin scouring pad.
