Physical and chemical properties of wool surface significantly affect the absorbency, rate of dye bath exhaustion and fixation of the industrial dyes. Hence, surface modification is a necessary operation prior to coloration process in wool wet processing industries. Plasma treatment is an effective alternative for physiochemical modification of wool surface. However, optimum processing parameters to get the expected modification are still under investigation, hence this technology is still under development in the wool wet processing industries. Therefore, in this paper, treatment parameters with the help of simple dielectric barrier discharge plasma reactor and air as a plasma gas, which could be a promising combination for treatment of wool substrate at industrial scale were schematically studied, and their influence on the water absorbency, mechanical, and dyeing properties of twill woven wool fabric samples are reported. It is expected that the results will assist to the wool coloration industries to improve the dyeing processes.

Colloidal suspensions prepared with nonaqueous liquids are important in ceramic processing operations such as tape casting, slip casting, etc. [1,2]. However, investigations of the properties of such suspensions are limited. In the present work, the suspension behavior of Al2O3 and silicate glass powders was studied using two nonaqueous liquids – methanol (MEOH) and methyl isobutyl ketone (MIBK). Rheological, sedimentation, and electrokinetic properties were determined for various mixed liquid ratios. The effect of polyvinyl butyral resin, a polymeric binder, on silicate glass suspension properties was also investigated.
