The objective of this research was to verify the feasibility use newly synthesized biopolymer materials for sizing cotton yarns based on basic principles chemical modification. Research included acid hydrolysis potato starch up controlled molar masses together with graft-polymerization and methacrylic onto hydrolyzed improve hydrophilicity solubility, increase capability film forming, adhesive potential avoid retrogradation phenomena. objectives were primarily focused finding an appropriate, environmentally-friendly productive agent via analysis systematization a large number synthesis methods in conjunction characterization properties graft-copolymers. results showed that potassium persulfate initiator most efficient grafting starch, while azobisisobutyronitrile (AIBIN) acrylic (AC). FTIR confirmed new products from synthetized obtained. rheological copolymers shows higher viscosity grafted indicating good stability starches. Ecological improvements have been established through high desizing degree as well physical-mechanical yarn, abrasion resistance decrease yarn surface hairiness noticed. derivatives especially (MAA), (KPS) initiator, confirmed. Anova statistical determined influence entire process individual parameters.
