Study on the one-bath dyeing of wool/PTT blends (Part Ⅱ)
This paper is the second part of a series on the dyeing of blends of polytrimethylene terephthalate (PTT) staple and wool. The compatibility between Terasil disperse dyes and Lanasol reactive dyes in the same dye bath, the effects of processing parameters such as pH, temperature and the rate of temperature increase on union dyeing of PTT and wool were also examined. The degree of damage to wool fibres at different dyeing temperatures (with and without dyes) was measured using an Australian standard testing method for alkali solubility. The results have shown that most Terasil disperse dyes achieved the highest dye-uptake on PTT staple at 110℃; Terasil dyes and Lanasol dyes showed good compatibility in one-bath dyeing under weak acid conditions at temperatures lower than 120℃. An optimised dyeing technique was developed which minimized the staining problem of Terasil disperse dyes on wool and gave stable union-dyed wool/PTT blended products with higher colour fastness, and lower damage to wool than encountered with normal wool/PET blend dyeing processes.
