Biosafety evaluation and quantitative determination of poly (hexamethylene biguanide) (PHMB) coated on cellulosic fabrics by Kubelka–Munk equation
It is difficult to directly determine the quantity of cationic finishing agents on the surface of cellulosic fabrics. Herein, we report a direct and feasible method by Kubelka–Munk equation to quantify the cationic poly (hexamethylene biguanide) hydrochloride (PHMB) adsorbed onto cotton fabrics based on the principle of formation of a stable blue dye between PHMB…

A salt-free, zero-discharge and dyebath-recyclable circular coloration technology based on cationic polyelectrolyte complex for cotton fabric dyeing
Textile industry is one of the most polluting industries due to the large quantities of dyeing wastewater it generates and discharges. Herein, we report an eco-friendly and sustainable circular coloration technology based on cationic polyelectrolyte complex to realise salt-free, zero-effluent-discharge circular dyeing for cotton fabrics with a recyclable dyebath by using a typical cationic polyelectrolyte…
