Abstract
Polyurethane acrylate (PUA) copolymers were synthesized following three step synthesis using toluene-2,4-diisocyanate, poly (2-methyl-1,3-propylene glutarate) diol terminated, 2-hydroxyethylacrylate (HEA) and butyl acrylate (BuA) via emulsion polymerization technique. The conventional spectroscopic characterization of the samples with FT-IR was in accordance with proposed PUA copolymer structure. The synthesized PUA copolymer samples were applied using dip-padding techniques on mill desized, scoured, bleached, printed, 100% cotton combed satin, striped weave fabrics. The emulsion stability evaluation and pilling rating showed reciprocal dependence on the percentage of butyl acrylate (BuA) and dual dependence on the concentration of vinyl terminated polyurethane prepolymer. The results revealed that by decreasing the mole ratio of polyol the emulsion stability and pilling rating drastically increased.
