Starches, especially high amylose starches containing nonionic, basic (cationic) and acidic (anionic) groups, preferably hydroxyalkylether (non-ionic), tertiary amino, cyanamide or quaternary amino (cationic) and sulfonic acid or sulfonate groups or carboxylic or carboxylate, or phosphate or phosphonate (anionic), in the starch molecule, are prepared which are especially useful for sizing threads or yarns of mixed fibers such as, for example, cotton fibers and polyester fibers, viz., polyethylene terephthalate fibers, and hydrophobic fibers that are difficult to size.
