    摘要： A composition for the elimination of cellulosic dye cross staining when dyeing cellulosic and synthetic blended fabrics in a dye bath. The composition includes a first component including polyvinylpyrrolidone polymer having a mwt. of between about 15,000 to 40,000 and the balance water. In the preferred embodiment, the composition includes a second component including dyestuff including dyes and polyvinylpyrrolidone polymer. Dyeing textile articles having at least two different types of fibers selected from the group consisting of cellulosic and synthetic fibers using the present invention produce a dyed article in which the cellulosic fibers are dyed and the synthetic fibers have a Class Value of greater than about 3 when measured according to the AATCC Gray Scale for Color Change.
