Textile-reactive particles

Eor particle fixation, the textile material is exposed to a solution, dispersion, or emulsion of the textile-reactive particles by conventional methods such as soaking, dipping, spraying, fluid flow, or padding, in which a catalyst may be present in the medium. The actual fixation takes place in the curing stage, which can proceed while the textile is still in contact with the particle solution, or preferably after the drying... 

Wool and other animal fibers contain hydroxyl, amine, carboxylate, and thiol groups that can easily react with nanoparticles. Synthetic fibers usually have a limited number of reactive groups, while ceUulosic fibers have hydroxyl groups as the only reactives. To increase the possible particle-textile combinations, a bifunctional molecule can be used to link an amine-reactive particle with cellulose in order to attach reactive amine groups on the cellulose fibers. 

The efficacy of diamond and metal-alloy electrodes for the degradation of the textile dyes Basic yellow 28 and Reactive black 5 was also followed by RP-HPLC. The chemical structures of the textile dyes under investigation are shown in Fig. 3.56. An ODS column (150 X 4.6 mm i.d. particle size 5 jttm) was employed for the RP-HPLC determination of... 

ABSTRACT UV light induced degradation of textile dye, reactive red MSB has been carried out on Ti02 and ZnO semiconductor particles. Spectrophotometer and COD techniques have been used to elucidate the details of dye decolourisation and degradation. The experiments have been carried out with different amount of catalyst, various concentration of dye solution, different irradiation time and in the presence of air. The reactive red MSB has been degraded to colourless end products. The results suggest that the photocatalytic degradation of textile dye may be a viable method for the safe disposal of wastewater.

Figure 2.4 shows a schematic diagram of a plasma device and different reactive species (Yousefi et a/., 2003). Plasma conversion of the feed gas produces chemically active particles that are able to modify the textile surface through chemical reactions at the surface. Various surface modifications can be obtained depending on process parameters such as ...
