Cotton cationization with low molecular weight or polymeric cationic modifiers allows the effective dyeing of cotton substrates reactive dyes under salt-free and more environmentally friendly conditions. The current work focuses on spectroscopic study intermolecular interactions, which dictate physicochemical process associated fabric dyeing. Water-soluble copolymers vinyl benzyl chloride (VBC)...

We describe the fastest dyeing of TiO2 photo-electrodes for dye-sensitized solar cells reported to date (<2 min) at room temperature giving η = 7.5% for an N719-SQ1-CDCA mixture which is significantly higher than devices dyed for >12 h using the same dye mixture (η = 5.5%). Time-lapse photography has been used to monitor the ultra-fast co-sensitization. The data show significantly different dye...

With the development of dyeing wastewater treatment biotechnology, the advantages of bioaugmentation bacteria gradually catch people’s eyes. Therefore, its construction and application research has also attracted the attention of the majority of scholars. This article summaries the construction and application of bioaugmentation engineered bacteria used to treat dyeing wastewater in recent year...

The polyester (100%), cotton (100%) and Polyester / Cotton blend fabrics (65 / 35; 50 / 50 & 35 / 65) were treated with sodium hydroxide followed by hydrophilic finishing and dyeing to impart hygroscopic and dyeing characteristics. Then the finished fabric was tested for k/s value, fastness properties, wetting behaviour, water retention, wicking behaviour and static charge respectively. The sod...
