Abstract
Different dyeing auxiliaries were applied to make dyeing temperature decreased from conventional 98 ℃ (boiling coloration) to 75~80 ℃, for conventional boiling coloration of wool fiber always cause certain damage. Dyeing time was reduced for 20%~30%, low temperature auxiliary was chosen, and dyeing process with low temperature auxiliary was investigated by comparing dye-uptake, color fastness, auxiliary dosage, dyeing time and dyeing temperature etc. The results showed that, under 80~85 ℃, low temperature auxiliary can make wool knitting achieve conventional dyeing apparent depth, color fastness and dye permeability reached the same level as conventional dyeing process. The breaking strength and breaking elongation of wool fibers after dyeing improved definitely than conventional dyeing process. The low temperature dyeing process can reduce the damage for wool fiber that brought by dyeing temperature, fiber strength enhanced for 10%~15% comparing with conventional dyeing, and fiber spinnability improved significantly, while dye fastness was essentially unchanged from conventional dyeing.关键词
