Abstract: A method for coloring fibers or fibrous materials where the fibrous material is initially chemically pretreated in order to achieve natural/white color for the fibrous materials. Next the pretreated fibrous material, a polymer base, and the colorant concentrate(s) are combined under suitable conditions to form a biocomposite mixture. The chemical pretreatment of the fibrous material prevents damage from being done to the fibrous material, such that the fibrous material retains its strength enhancing properties when combined with the polymer to form the biocomposite mixture. Additionally, the chemical pretreatment enables the fibrous material to chemically and mechanically bond with the colorant when combined into the biocomposite mixture.

Abstract: A method for producing a rubber wet masterbatch includes a solidifying step of mixing a slurry solution containing a filler and a dispersing solvent with a rubber latex solution, and solidifying the resultant mixture to produce a filler-containing rubber solidified product, a dehydrating step of using a first uniaxial extruder to dehydrate the filler-containing rubber solidified product while the solidified product is heated into the range of 100 to 180° C., thereby producing a rubber wet masterbatch, and a drying plasticizing step of using a second uniaxial extruder to plasticize the rubber wet masterbatch while the masterbatch is heated into the range of 120 to 180 C, thereby producing the rubber wet masterbatch further decreased in water content by percentage. The method does not have cooling step between the dehydrating step and the drying plasticizing step.
