Abstract :Waterborne-polyurethane dispersions, consisting of polyol and polyisocyanates building blocks are conventional finish materials for various applications in textile industry, particularly in denim industry. This study aims to prepare a multifunctional polyol block, which is compatible with commercially available polyisocyanates, for polyurethane formation. Therefore, well-defined polymers having both hydroxyl and tertiary amine functions prepared via controlled radical polymerization technique namely atom transfer radical polymerization insert ignore into journalissuearticles values(ATRP);. Hydroxyl functions are considered as cross-linking domains with polyisocyanate to form polyurethane and tertiary amine moieties are considered as quaternarization domains with different length of alkyl-bromides. 1 H-NMR and Dynamic light scattering insert ignore into journalissuearticles values(DLS); techniques are used for structural characterization and thermal stability evaluation of synthesized polymers respectively. Those synthesized materials are primarily used for surface modification of cellulosic fabrics to achieve wash-fast antimicrobial coatings. Dyeing studies with indigo dyestuff is conducted with both polymer treated and non-treated fabrics. Dyeing studies showed dye-uptake capabilities of polymer coated samples are found to be higher than non-treated fabrics. Datacolor spectrophotometer SF 600 Plus is used to evaluate color measurements.
