A composite filament includes a core particle comprising a styrene/acrylate polymer resin, and a shell comprising a styrene/acrylate ionomer resin, wherein the styrene/acrylate ionomer resin comprises a metal ion acrylate monomer, and methods of making thereof. Various articles can be manufactured from such composite filaments.

A water washing device for carbon fiber filament and a method of water washing using the same are provided. The water washing device divides a temperature controller and the carbon fiber filament by disposing a division plate in a water washing tank; thus a temperature of washing water can be accurately controlled. Further, spray nozzle(s) can be controlled to enhance washing effect of the carbon fiber filament.

A method for the production of a glassy metal polymer composite is disclosed. The method comprises adding a polymer and a metal to an extruder, wherein the extruder is heated to an extrusion temperature greater than the melting point of the polymer and the melting point of the metal; mixing the metal and the polymer in the extruder for a predefined residence time; and co-extruding the composite from the extruder.

An anti-counterfeiting yarn includes a uniformly distributed up-conversion fluorescent material and a polymer, wherein the up-conversion fluorescent material comprises a maximum weight percent of about 1.8%. A method of preparing an anti-counterfeiting yarn includes mixing functional polymer chips containing up-conversion fluorescent material with polymer chips not containing up-conversion fluorescent material in a ratio such that the fluorescent material is uniformly distributed in the mixture, melting the mixture, extruding the melt into filaments, and producing anti-counterfeiting yarn through spinning and drawing the filaments.

The present invention discloses a simple mechanical method of fabrication of sub-micron aligned free standing hydrophobic and oleophilic fibers of polystyrene waste using extracts obtained from the peel of any citrus fruit such as orange, lemon, sweet lime, kinnow etc. as solvent. Fibers are aligned and useful in making different geometries. Process of making film using this process is facile and fast and film obtained is free standing film. Process set-up have minimum requirement and is inexpensive. This method is simple and flexible with respect to set-up and process. This process has the potential of being industrialized. Therefore, this method can be beneficial in dealing with both the orange peel and polystyrene waste.
