The dyeing characteristics of fibers form three Acala cotton varieties, i.e., Maxxa, SJ-2, and SJC-9, are investigated using direct and reactive dyestuffs along with the Goldthwait cotton maturity test. Dyed and less-dyed fibers are detached from the dyed seed fibers, separated, and characterized by seed fiber weight, single fiber strength, and color measurement. With Direct Blue 1, SJC-9 fibers are dyed to the darkest shade across all seed fiber weights, whereas the Maxxa fibers have the lightest shade. The SJC-9 seed fibers have the least amounts (～5/100) of less-dyed fibers and the proportions of such fibers are independent of seed fiber weights.
