て２次的な染料の移行汚染が起こる。The disperse dyes used to dye synthetic fiber sheets have good compatibility with coating resins and solvents, so the disperse dyes may migrate into the coating film during heat treatment or heat setting during the coating process, or they may migrate into the coating film after the coating process. However, as time passes, the disperse dye gradually migrates into the coating film.If the disperse dye migrates into the coating film, for example, if the disperse dye migrates into the coating film, for example, if another coated synthetic fiber sheet is stacked and pressed for a long time. If left untreated, dye migration contamination known as color migration occurs. Alternatively, when a coated synthetic fiber sheet is wrapped in a packaging film, dye migration contamination occurs first on the film, and then the dye in the contaminated film migrates to other materials, resulting in secondary dye migration contamination. happens.

上の障害になる。In order to suppress this migration contamination of dyes, it has been proposed to use resins with poor compatibility with disperse dyes (for example, melamine resins) as coating resins (Japanese Patent Application Laid-Open No. 1983-1993).
-95583, JP-A-57-187385, and JP-A-62-28484), if these countermeasures were taken, the effect of transfer sublimation would not be sufficient and the texture would be hard. In addition, in the case of synthetic fiber sheets coated with resin, depending on the yarn used, the tension balance between the warp and weft directions may be affected. Curling tends to occur after cutting the sheet. The curling phenomenon becomes an obstacle in sewing.
この発明は、上記事情に鑑み、前述の染料の移行汚染が
起こり難いコーティング加工を合成繊維シートに施せ、
しかも、切断後のカール現象を抑えられる方法を提供す

。After the acid reduction treatment, the synthetic fiber sheet is further coated with a porous particle-containing resin coating. For example, using a resin solution in which a synthetic resin is dissolved in a polar organic solvent and porous particles are added, a coating process is performed using the same wet method as described in detail above: applying the resin solution, dipping in water, washing with hot water, and drying. It is to give. The same coating resin and polar organic solvent can be used as in the case of the resin coating described above. The coating film thickness is about 20 to 250p.

は、シワ取りなどの目的で行われるものである。After applying the porous particle-containing resin coating, finishing setting is performed at a temperature lower than the above dye heat treatment temperature. This is because if the finishing set temperature is higher than the dye heat treatment temperature, the dye will bleed out again. Heat treatment in the finishing set is usually performed at a temperature of 150° C. or lower. This finishing set is performed for the purpose of removing wrinkles and the like.

下させずに済むのである。In this invention, a porous particle-free resin coating is applied, a dye removal process is performed, and then a porous particle-containing resin coating is applied, because the dye molecules that are easily transferred are removed first in the dye removal process. Very few dye molecules are adsorbed to the porous particles in the subsequently formed coating film during the processing stage, and the original function of the porous particles, which is to adsorb dye molecules that migrate over time, is hardly degraded. That's all there is to it.

には出ない。[Function] In the synthetic fiber sheet subjected to the coating processing method of the present invention, dye migration staining is extremely unlikely to occur. This is because, after the coating process, the number of dye molecules that leave the coating film and migrate to other objects is smaller than in the past. Dye molecules that are easy to migrate have already been removed in the dye removal process, and the dye molecules that migrate over time are captured by the porous particles in the coating film and do not come out of the coating film.

ある。Since the porous particle-containing resin coating is applied after the dye removal step, the original function of the porous particles does not need to be degraded during the processing stage. This is because fewer dye molecules are adsorbed onto the porous particles during processing.
また、対染料熱処理および仕上げセントの際の２回の熱

象が起こり難い。In addition, since the synthetic fiber sheet has been subjected to two heat cycles during dye heat treatment and finishing centration, curling phenomenon after cutting the synthetic fiber sheet is less likely to occur.

であった。In addition, if we compare the results between Example 1 and Comparative Examples 1 to 3, it is found that the dye removal process and the presence of porous particles are each effective, but as in Example 1, it is only when both are present that the dye is removed. It is clear that migration contamination can be sufficiently suppressed. In addition, when cutting the processed jitodo for Example 1 and Comparative Example 3, it was found that the heat history of one time of finishing set was lower than that of the example which went through two heat histories of dye heat treatment and finishing cent. In the case of the comparative example, the curling phenomenon was noticeable.
