    Abstract: PURPOSE:To improve wear resistance, yellowing and browing resistance, wrinkle resistance, etc., of silk yarn product, by dissolving an epoxy compound and a reaction catalyst in a mixed solution of a polar approtic solvent and water to give a composition, impregnating the composition into a silk yarn product and subjecting the yarn to wet heat treatment. CONSTITUTION:An epoxy compound such as a compound having two or more epoxy groups and =100 deg.C boiling point, such as dimethyl sulfoxide and water in the weight ratio of 95:5-51:49 to prepare a composition, which is impregnated into a silk yarn product, pressed and then the silk yarn product is subjected to wet heat treatment in high-temperature steam at >=100 deg.C to readily improve functions such as wear resistance, yellowing and browning resistance, wetting resistance, wrinkle resistance and washing resistance while maintaining characteristic properties of silk yarn.

    Abstract: PURPOSE:To draw a pattern with excellent sharpness, by forming the pattern on a surface containing high-temp. hydrophobic heatreversible polymer compound using a coloring material composite of which temp. is kept higher than phase transition temp. of the polyer compound. CONSTITUTION:A pattern is drawn on a surface of polymer composite containing high-temp. hydrophobic heat-reversible polymer compound by means of a coloring material composite of which temp. is kept higher than phase transition term. of the polyer compound. Alternately, the temp. of a polymer composite surface containing high-temp. hydrophobic heat-reversible polymer compound is kept higher than phase transition temp. of the heat-reversible polymer compound and a pattern is drawn by means of a coloring material composite. The high-temp. hydrophobic heat-reversible polymer compound is preferably one mainly containing polyvinyl methylether with more than 50 deg.C phase transition temp. and polyacrylamide derivative.

    Abstract: PURPOSE:To promote the reaction of a polymer and a compound using minimum amount of water necessary for the processing treatment by impregnating a fiber with a compound reactive with the fiber constituting polymer, laminating with a hydrated polymer gel sheet capable of reversibly sucking and releasing water by temperature change and heating the laminate at a temperature above the phase-transition temperature of said gel. CONSTITUTION:For example, in the thinning processing of a polyester fiber with sodium hydroxide or cotton fiber with cellulase, the fiber is impregnated with the compound reactive with the fiber constituting polymer and subjected e.g. to intermediate drying. The treated fiber is laminated with a hydrated polymer gel sheet capable of reversibly sucking and releasing water by temperature change (e.g. crosslinked gel of polyvinyl methyl ether) and the laminate is sealed, heated at a temperature above the phasetransition temperature of the polymer gel and maintained at the temperature. Water is released from the gel by this treatment to promote the reaction of the polymer and the compound in moistened state. The use of the gel is effective in preventing the waste of large amount of water in contrast to conventional process and enables the supply of necessary minimum amount of water in high efficiency to perform an energy-saving processing of the fiber.

    Abstract: PURPOSE: To enable clear white and colored discharge printing in exhibiting an excellent resist printing property without using a reducing agent by utilizing a viscous solution of a polyamide derivative having thermal reversibility as a resist agent. CONSTITUTION: A viscous aqueous solution of a polyacrylamide derivative having thermal reversibility phase transversal to hydrophilic property at a low temperature and hydrophobic property at a high temperature is prepared, the aqueous solution is printed to a natural or a synthetic fibers cloth according to a normal method and a discharge printing colored glue is overprinted (or dipped dyed) at a temperature higher than a phase transition point of the thermally reversible compound. By using the thermally reversible poste, an excellent resist printing effect is exhibited without using a reducing agent and clear white removing or colored discharge printing can be performed.

    Abstract: PURPOSE:To obtain an organic semiconductor stable in air and excellent in heat resistance, film smoothness, variety of developed colors, etc., by doping a specified polymer obtained by introducing a heterocyclic group other than a thiophene group into the molecular chain of a thiophene polymer with an anion. CONSTITUTION:The purpose organic semiconductor is prepared by doping a polymer consisting of repeating units of formula I (wherein R is formula II, III or IV) with an anion (e.g., tetrafluoroborate ion or perchlorate ion). Said polymer is produced by electrolytically polymerizing a compound of formula V, VI or VII. Although the polymer obtained by the electrolytic polymerization has been doped with the anion of the supporting electrolyte used, the dopant can be removed by reversing the polarity in the electrolytic polymerization to give a polymer in a neutral state. The obtained polymer can be suitably used as an electrode material, a solar battery material or the like.
