A Study on the Soil-Redeposition in Drycleaning Process

摘要: To investigate the soil-redeposition and color change on dry-cleaning, white and, dyed, fabrics of cotton, silk, polyester viscose rayon were put into ordinary commercial dry-cleaning machine with soiled cloths. The solvents used hydrocarben, perchloroethylene fluorocarbon. From result, we obtained following conclusions by examining soil-redeposition, difference tenacity cotton fabric. 1. In case fabrics, as a whole, shows lowest soil redeposition. When distillation process is adopted, rate redeposition lowered. hydrocarbon sdvent. order fibers are following; cotton> rayon> silk> polyester. 2. dyed between redeposited originals () similar in pattern, rayon, silk treated pure ( ) also validated little. It seems to be due bleeding dyestuffs from fabrics. 3. There little solvent. supposed that damage more influenced repetitive mechanical action during than acidity solvent having acid value 0,14.
