c2017 The Korean Fiber Society Abstract: The application of madder and indigo plant dyes with various concentrations on five different cellulose blend samples, hansanmoshi/cotton, tencel/cotton, cotton, deodorizing processed cotton yarn, bamboo yarn, resulted in various strengths of color, which is useful for versatile towel design. For madder and indigo dyes, 80 C and 40 C were respectively the optimum dyeing temperatures, and 20 min of dyeing time was sufficient to achieve reasonable color strength. Both hansanmoshi-blend towel and tencel-blend towel dyed with natural madder and indigo showed excellent fastness properties: the rated washing fastness, rub fastness, light fastness, and perspiration fastness were 3−4, 4−5, 4, and 4−5, respectively. Those towels exhibited excellent functionality such as 99.8% deodorization effect and 94% antimicrobial activity with no detectable formaldehyde in an assay.
