The performance of amphoteric starch containing quaternary ammonium and carboxylic groups was investigated based on film behavior, adhesion to fibers, and anti-flocculation to anionic substances for warp sizing, The effect of chemical modification on the performance was explored by use of film casting, roving sizing, and light transmittance. The introduction of cationic and anionic groups simultaneously onto starch eliminated the problems caused by cationic starch flocculation with anionic ingredients if the mole ratio of cationic groups to the anionic ones was less than or equal to 4:1, The film elongation-at-break and flexibility increased with the increased degree of substitution, while the film strength decreased. The adhesion to fibers increased as the ratio of DSc to DSa increased.
