One-bath Dyeing of Polyester/Wool Blend with Disperse Dyes

The role of auxiliary LAB as vehicle in dyeing polyester/ wool blends with disperse dyes is described. Dye exhaustion and bonding on polyester/wool samples are studied under different experimental conditions - the LAB amount, the temperature and pH value - to achieve optimum conditions. The results are compared with those obtained with and without conventional dyeing auxiliary products. Although dye exhaustion is higher in the presence of commercial carriers, the dye bonded increases markedly in the presence of auxiliary LAB in both fibers. The role played by auxiliary LAB in polyester/wool blend dyeing can provide a new method for this process.

Determining Compatibilities of Reactive Dyes in Pad Dyeing

Compatibilities of reactive dyes were conventionally shown by exhausting curves. But the change of proportion of dyes in padding dyebath was difficult for pad dyeing to be described by these curves. In this paper, a kind of simulation of pad dyeing process was used to determine dyestuff compatibility in pad dyeing for ramie and linen fabrics. Seven reactive dyes were divided into three groups and tested. The group with Cibacron Yellow C - 2R, Red C - R, and Blue C - R showed very good compatibility both for ramie and linen, and the other two groups of dyes gave out correspondingly low compatibilities in the pad dyeing tests. The results of the method for determining the compatibility of dyes displayed good consistency with the actul pad dyeing process.

Study on Dyeing of a Novel,Pro-environment Polylactic Acid （PLA） Fiber Yarn

Seventeen disperse dyes including anthraquinone, azo, methine, nitro, and quinoline dyes were applied to dye the Polylactic Acid （PLA） yarns at different conditions, and the dyebath exhaustion was determined. The result shows that C.I. disperse red 167, C.I. disperse orange 30, and C.I. disperse blue 284 have dye-uptakes greater than 80%. Therefore, they can be used as the three principal dyes for PLA yams. The experiment discovered that the dyes, because of their Monoazo and ester group contents, have a higher dye-uptake for the PLA fiber. The research on the optimization of dyeing techniques suggests that PLA yarn can obtain a high level of dyeing effectiveness at the following conditions： pH 4- 5, dyeing temperture 110℃ for 30- 40 min. Color fastness to perspiration, and waterwashing fastness increased 1 - 1.5 by the addition of the abstergent FB during the reduction clearing.
