  Abstract

This work aimed to evaluate the paste stability and desizability of new starch grafted copolymer [poly(sodium allyl sulfonate)-g-starch-g-poly(ethyl acrylate)] (PSAS-g-starch-g-PEA) for providing an important supporting role in sizing application. The PSAS-g-starch-g-PEA samples were prepared by grafting reaction of acid-thinned starch (AHS) with SAS and subsequent with EA in water phase. The PSAS-g-starch-g-PEA granules were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. Also, paste stability was assessed and desizability was investigated in terms of desizing efficiency, swelling ability of the film and time interval for the break of starch film in water. Compared with control AHS, the PSAS-g-starch-g-PEA had higher paste stability, desizing efficiency and swelling ability, and lower time interval required, concluding that the PSAS and PEA branches could promote the paste stability and desizability of starch. Increasing the number of both branches facilitated the paste stability and desizability. PSAS-g-starch-g-PEA displayed potential value in textile sizing field.
