Abstract
The influences of drycleaning by various solvent on the characteristics of 33 dyed fabrics, on the market, for Japanese silk kimonos (Japanese traditional costumes) were investigated experimentally. First of all, the removal effect of sodium chloride as a model of water soluble stains on these fabrics was tested. Then, the change in shade by stain removal agents was also examined. Results obtained in this study were as follows:
1) Since there was no remarkable change in shrinkage and shade of fabrics, the influences of the drycleaning on the characteristics of these fabrics were very little.
2) However, in some fabrics the spotting by water or by water solution of neutral detergent might cause remarkable change in color migration and in shrinkage.
3) The removing efficiency of sodium chloride stains was very poor in the case of prespotting in drycleaning by brushing or ultrasonic spotter that was used as a standard drycleaning technique for kimonos. By contrast, the removing efficiency of sodium chloride stains by steam spotting was very remarkable, though this method causes slight change in color and shrinkage for some kimono fabrics.
