Latest Patents

Kobayashi holds a patent for a nonwoven fabric designed specifically for printing purposes. This fabric is composed of long-stock synthetic resin yarns, such as polyethylene and polypropylene. The fabric features an ink-setting layer that is formed by coating, drying, and curing a resin composition containing acrylic resins, synthetic rubbers, and polyester resins. This layer exhibits excellent transfer properties and fixing abilities for oil inks commonly used in offset printing. It also prevents swelling or transformation of the nonwoven fabric due to petroleum high-boiling-point solvents found in the inks. The incorporation of a low-temperature cross-linking agent allows for cross-linking at lower temperatures, minimizing heat shrinkage or damage to the fabric. Additionally, the inclusion of fillers such as non-calcined clay, titanium dioxide, and calcium carbonate enhances the absorbability, drying ability, and fixing ability of the ink-setting layer.
