In this paper, newly developed blended knit was used. It was composed by Acrylate fiber and Dyeable polypropylene(DPP) fiber. As result of build-up dyeing test, acid dyes and disperse dyes respectively had good dyeabilities on 1% o.w.f. with Acrylate fiber and DPP fiber. Compatibility of trichromatic of disperse dyes was generally good for most dyes investigated and their critical absorption range were between 120℃ and 130℃. As depending on dyeing methods, there were many differences in dyeability. It was confirmed that 1-bath-1- step dyeing was most suitable when considering dye exhaustion yield and levelling property. Wash, rubbing and light fastness of knits were generally good in most dyes.
