Compared to conventional peroxide bleaching, using a bleach activator in a peroxide bleaching bath is an effective and kinetically more potent oxidation generating highly reactive peracid in situ, providing low-temperature bleaching with shorter dwelling time. In the presence of an activator, bleaching can be achieved at lower temperatures and reduced time relative to the conventional peroxide bleaching,...
Cationization of cotton brings advantages in the reactive dyeing process, such as eliminating the use of electrolytes and increasing color yield. However, high dye strike rates caused by the electronic attractions between anionic dyes and cationized cotton may result in poor levelness of dyeing, especially for light shades. For some monochloritriazine–monochloritriazine homobifunctional reactive dyes,...
Chemical cationization of cotton has been a subject of increased interest due to the ability of cationized cotton to attract negatively charged dyes, thus eliminating the use of electrolytes during dyeing and increasing color yield. However, electrostatic attractions between cationized cotton and anionic dyes also result in significantly increased dye strike rates, which may cause levelness problems,...
Layer-by-layer self-assembly deposition of polyelectrolytes on textile materials might provide a new approach to endue different functions to textiles. Two simple characterization methods for electrostatic self-assembly deposition of two typical polyelectrolytes, poly(sodium 4-styrenesulfonate) (PSS) and poly(diallyldimethylammonium chloride) (PDDA) on cotton fabrics were investigated in this paper...
