  • Patent number: 6939583
    Abstract: It is an object of the present invention is to provide fabric for use in ink-jet printing that can prevent not only “ink bleeding”, but also “white exposure”, “nonuniform coloration” and “back staining”. A further object of the present invention is the provision of fabric for use in ink-jet printing, consisting of two textures—napped and ground, which can be evenly ink-jet printed with no variation in color between both, while preventing the occurrence of “white exposure”, “nonuniform coloration” and “back staining”.

  • Patent number: 6471896
    Abstract: To provide a method for processing a cloth to form a three-dimensional design pattern on the cloth not only by a conventional printing system, but also by an ink-jet system. A method for processing a cloth to form a three-dimensional design pattern on the cloth, which involves two processes—one in which it is treated with a Solution A containing a salt formed from a phenol derivative and a hydroxide of an alkali metal or alkali-earth metal and the other in which it is treated with Solution B containing a chemical capable of restoring the salt in solution A to its original phenol derivative. The present invention is advantageous in using highly safe water-soluble chemicals, allowing their uniform application to a cloth to form a three-dimensional design pattern on the cloth.

  • Patent number: 6300260
    Abstract: Provided is a polyester fabric for ink jet recording which is suitable for outdoor use. A treating solution comprising a water-swelling resin (A) comprising a reaction product of a polycarbonate polyol and a polyisocyanate compound and having a sulfite group at the side chain and a number average molecular weight of 20,000 to 100,000; a water-swelling resin (B) comprising a reaction product of a polycarbonate polyol and a polyisocyanate compound and having a sulfite group at the side chain and a number average molecular weight of 5,000 to 15,000, wherein a blocking agent is reacted with active isocyanate groups positioned at both terminals of the water-swelling resin to mask the terminal isocyanates; and water-retentive microparticles (C) is applied to a polyester fabric, followed by heat-treating to form the fabric for ink jet recording.
