Abstract
Optimization of dyeing poly(lactic acid) fibers with vat dyes has been investigated. Conventional method for dyeing cellulose fibers with vat dyes was able to be applied for dyeing poly(lactic acid) fibers. It has become obvious that higher dyeing temperature and concentration of auxiliaries have negative effects on the dyeability of dyes on poly(lactic acid) fibers. Determination of optimal dyeing condition has also been investigated. We found that optimal concentrations of dyes and auxiliaries could be estimated through simple linear experimental equation.
