Dyeing Properties to Soybean/Flax Blended Yarn with Reactive Dyes
For producing more colorful soybean /flax blended yarns and fabrics and to evaluate the dye-ability of the blends yarn, two types of reactive dyes, containing mono- and bi-functional reactive groups, were studied. On basis of a number of experiments, influences of time and temperature, alkali dosage, addition of promoter are analyzed, the optimum conditions to soybean/flax fibers with Reactive Yellow K-R and Reactive Yellow B-4RFN are defined. Results of performance test indicate that both K-type reactive dyes and B-type reactive dyes have good colorfastness and levels, especially for light to moderate color, and B-types is better than K-types. The colorfastness of the dyed yarns can meet the general requirements.
