The effect of carriers on the dyeing of Courtelle S

Abstract

The extent to which the uptake of CI Basic Blue 3 on Courtelle S tow was enhanced by three derivatives of benzyl alcohol was found to be proportional to the amount of each carrier adsorbed by the fibre, with maximum dye uptake coinciding with maximum uptake of carrier by the fibre. Although the maximum extent of uptake of each carrier corresponded approximately to the aqueous solubility of the carrier at the dyeing temperature (80°C) used, results from a previous study on the carrier action of benzyl alcohol on Courtelle S were employed to demonstrate that maximum uptake of all four carriers was not simply related to aqueous solubilty. The solubility parameter concept was used to demonstrate that the maximum extent of carrier uptake was related to the Sa value of the carrier. The linear relationship obtained between the maximum extent of uptake of each carrier and the 6 , value of the carriers was considered to demonstrate that polar forces primarily contribute to carrier-acrylic fibre interaction.

Preparation and properties of deep dye fibers from poly(ethylene terephthalate)/SiO2 nanocomposites by in situ polymerization

“…), which are rapidly absorbed, have been used to accelerate the dyeing rate. But many effective carriers are also suspected environmental hazards 7–11. Thakore et al reported a dyeing process using ultrasonic to form and break small bubbles, making the dyeing better at low temperatures achieving levels comparable with dyeing at boiling using carriers 12–16.…”

New disperse dyeing method of poly(p-phenylene benzobisoxazole) fiber pretreated with polyphosphoric acid

“…As a result, the glass transition temperature (T g ) and dyeing transition temperature (T d ) of the fiber may be expected to be decreased during the carrier dyeing process, and the diffusion rate of dyes and the dye exhaustion to be increased [18,19]. Therefore, carriers could be used in the coloration of synthetic fiber, for example, for acrylic, PVC and polyphenylene sulfide fibers with cationic dyes [19][20][21][22][23], and for polyester and triacetate fibers with disperse dyes [24][25][26].…”
