Abstract: Comparing with conventional pretreatment, one bath low temperature processes for loose cotton were carried out with 4 types of auxiliaries by means of whiteness, strength and elongation properties, degree of fixation, K/S value and ΔE value. The results showed that main performances except levelness of one bath

dyeing enzyme 517(ODE517) were relatively superior to other auxiliaries.
