て水洗する必要があった。2. Description of the Prior Art In order to remove dyes hydrolyzed and unfixed dyes during dyeing of a cellulosic fiber with a reactive dye to improve wet fastness, the dyed cellulosic fiber material is washed with water and a detergent. It is necessary to wash with.
For this reason, conventionally, reactive dyeing products of cellulosic fiber materials are dyed with higher amine ethylene oxide adducts, higher fatty acid ethylene oxide adducts, and naphthalene sulfonate formaldehyde condensates (Dyeing Industry, 26 (19)
78) pp. 607-612), and polyacrylic acid salts (Japanese Patent Publication No. 59-29718). Although these detergents have good effects, in the case of dyeing with reactive dyes, the amount of dye used is so large that washing with a large amount of water is necessary to completely remove the dye remaining in the washing bath. was there.

At that time, the dyed product changed over time, and a clear product could not be obtained.

御することは非常に困難であった。[Means for Solving the Problems] As a result of various investigations on the method for cleaning a reactive dye-dyed product of a fiber material containing a cellulosic fiber material, the present inventors have found that peroxodisulfate is a cleaning agent for the reactive dye-dyed product. It was found that the dye in the washing bath is chemically decomposed to become colorless or decolorized, and the washing step after washing can be greatly shortened. However, this reaction is very sensitive to the pH of the treatment bath, and it is very difficult to obtain a stable cleaning effect. Further, peroxodisulfate produces sulfuric acid due to the decomposition reaction and it is very difficult to control the pH. It was difficult.

That is, in the present invention, the residual reactive dye is easily decomposed by dyeing the cellulosic fiber material with the reactive dye and then treating with a detergent mixed with peroxodisulfate and a pH buffer at 80 to 105 ° C. Moreover, it was found that the decomposition reaction was easily controlled, and the water washing following the decomposition was completed in an extremely short time to obtain a clear finish.

It is 00 parts by weight. The concentration of the detergent in the washing bath depends on the concentration of the dye to be washed, and the higher the concentration of the dye, the higher the concentration of the washing liquid is required, but it is usually 0.01 to 2 g / l as peroxodisulfate.

ス系繊維との反応基が切断される可能性がある。Degradation of the dye in the washing treatment bath with peroxodisulfate is greatly affected by the pH of the treatment bath. The stronger the acidity, the more easily the dye is decomposed, and the stronger the alkalinity, the more difficult it is to decompose. However, when the acidity becomes strong, the decomposition of the dye becomes too strong, and even the dye that has been reactively fixed on the fiber is decomposed. Therefore, it is necessary to avoid lowering the pH of the treatment bath to 5 or less. On the other hand, although the reactive group of the reactive dye and the OH group of the cellulosic fiber react, the pH stability varies depending on the reactive group of the dye, and the vinyl sulfone dye has a pH
Alkali of 9.5 or more may cleave the reactive group with the cellulosic fiber, and monochlorotriazine dye and dichloropyrimidine dye may cleave the reactive group with the cellulosic fiber at pH 5 or less.

As H, 5 to 10, preferably 6 to 9.5, and more preferably 7 to 9 is suitable. When peroxodisulfate is used alone, sulfuric acid is generated by the decomposition reaction, and it is very difficult to control the pH of the treatment bath. In order to control the pH, a pH buffer is used in the present invention. In dyeing a cellulosic fiber material with a reactive dye, an alkali such as sodium carbonate or trisodium phosphate is used at the time of dyeing, which is often brought into a washing bath, or as described above, peroxodisulfate. The decomposition of produces sulfuric acid. Depending on the amounts of these alkalis and acids, the bath solution may change from a strong acidity of about pH 2 to an alkalinity of about pH 11. For this reason, the above pH buffer must be a stable buffer system in which the pH range used does not fluctuate neither to the acidic side nor to the alkaline side. In the washing according to the present invention, the dye decomposition action of peroxodisulfate occurs at 80 ° C. or higher,
~ 105 ° C, preferably 90 ~ 105 ° C.

組成物として使用出来る。As a result of the washing treatment according to the present invention, the concentration of the dye coloring the washing bath is extremely lowered, so that even if the dyed product has a dark color, the number of times of rinsing after the washing treatment is about two. The detergent used in the cleaning method of the present invention can be used as an aqueous solution composition by combining the above-mentioned peroxodisulfate and a pH buffer component.

しい。However, peroxodisulfate is not completely stable when made into an aqueous solution, and decomposes with the passage of time to gradually decrease the effect as a detergent. Therefore, for long-term storage, it is desirable to use not an aqueous solution of peroxodisulfate and a pH buffer component, but a composition in which both are powder-mixed.

え、分解反応が充分に進行し洗浄効果が良い。1. When the cleaning agent of the present invention is used, compared with the commonly used cleaning agents such as sodium polyacrylate and fatty acid ethylene oxide adduct, rinsing is completed in a short time with water, and the dyed product is not discolored. 2. When peroxodisulfate is used alone, in the case of a reactive group that is weak against alkali such as vinyl sulfone dye, it is often neutralized before washing.
The decomposition reaction of the dye is so strong that the dyes fixed on the fibers are decomposed and discolored as in Comparative Examples A to B, but the cleaning method using the cleaning agent of the present invention does not cause such a pH decrease and discolors. Does not happen. 3. In the case of monochlorotriazine dye, it is not neutralized before washing, but in this case the alkali used at the time of dyeing was brought into the washing bath and used peroxodisulfate alone,
Since the pH of the cleaning treatment bath is too high, the decomposition reaction does not sufficiently occur and the cleaning effect becomes poor. In the cleaning method using the cleaning agent of the present invention, such a rise in pH due to the introduction of alkali is suppressed, and the decomposition reaction proceeds sufficiently to have a good cleaning effect.
