Abstract

PURPOSE: To enable to perform a spot hydrization without inducing lowering of strength or discoloring by previously applying an alkali and a humectant to a polyester fiber structural material comprising a modified polyester and a non-modified polyester heat-treating. CONSTITUTION: A practical discharge printing without inducing a lowering of a strength of a non-modified polyester is enabled by previously adhering an aqueous sizing agent in which a polyester fiber structural material comprising a modified polyester, e.g. polyethylene terephthalate is copolymerized with isophthalic acid and/or a metal salt-containing sulfonate group-containing dicarboxylic acid and a non-modified polyester, added with an alkali such as caustic soda and a humectant in a pattern-like, drying and heat-treating at 110-190 deg.C dry heat or a superheated steam. A colored spot-hydrized material without discoloring is obtained by using an alkali-resistant dispersing dye.

<Prior art> Conventionally, as a method for contacting polyester fiber structures, a technique disclosed in Japanese Patent Publication No. 37-7393, in which polyester fibers treated with amines, inorganic acids, and oxidizing agents are easily hydrolyzed by alkaline, was used for contacting modified polyesters. A method is known in which a polyester fiber structure made of unmodified polyester is contacted with only a modified polyester component. However, these have practical problems in that the strength of the unmodified polyester fiber portion that remains even after falling down is low, it is easily discolored, or the strength decreases over time.

It takes place for a minute. Furthermore, when an alkaline hydrolysis accelerator such as dimethyllauryl benzyl ammonium chloride is added, the caustic soda concentration can be lowered, the time can be shortened, and the temperature can be lowered. This alkali treatment removes the heat-treated modified polyester component to which the alkali and wetting agent have adhered in advance. For the purpose of improving the hand of the contact-processed product according to the method of the present invention, it is possible to further carry out conventional alkali weight reduction, or to carry out the alkali contact simultaneously.
