Low temperature dyeing of PLA fabric

Wei Zhang

Abstract

Low-temperature disperse dyeing of PLA fabric was carried out with carrier CWP-910.Influences of carrier dosage,dyeing time and pH value of dyeing bath on dyeing result were discussed.It was found that CWP-910could improve solubility of disperse dyes obviously,and thus realize low-temperature dyeing of PLA fabric with disperse dyes.The optimum low-tem-perature dyeing process was determined as follows: disperse dyes 4% (owf),CWP-910 3g/L,and dyeing at85℃ for 40 mi-nutes in neutral bath.The dyeings featured good color fastness to washing and sublimation.
