Abstract. This paper has discoursed about the probability of polymers used to some finishing process of textile. Those polymers have been untoxic and water-soluble macromolecules with characteristic groups. The role of polymer at finishing textile, for example the sizing process or the bleaching process, is warp yarn impregnating to giving an enough strength or reduce a speed peroxide decompose and decrease the risk of damage the cotton fibers. After sizing process, to went the desizing process comprising only water treatment (600C, 15 min) and a drying. The results of investigation the sizing and bleaching process have shown good effects, particularly mechanical parameters, and whiteness grades. Scanning electron microscopy has utilized to the structural and morphological changes understanding of the cotton fibre in sizing regime.
Key words:  polymers, sizing, desizing, bleaching, cotton, whiteness degrees, mechanical characteristics, scanning electron microscopy

PRIMENA NETOKSIČNIH POLIMERA
U PROCESIMA SKROBLJENJA I BELJENJA TEKSTILA
Rad govori o upotrebi nekih polimera u nekim procesima dorade tekstila. To su netoksični, vodorastvorljivi polimeri čije makromolekule imaju karakteristične funkcionlane grupe. Uloga polimera u doradi tekstila npr. u procesu skrobljenja ili u procesu beljenja je u impregniranju osnovine pređe i davanju dovoljne jačine ili u redukovanju brzine razlaganja peroksida i smanjenju rizika od oštećenja pamučnih vlakana. Posle procesa skrobljenja ide odskrobljavanje koje obuhvata samo obradu vodom (600C, 15 min) i sušenje. Rezultati istraživanja procesa skrobljenja i beljenja pokazuju dobar efekat, posebno mehanički parametri i stepen beline. Skaning elektronska mikroskopija je iskorišćena za razumevanje morfologije pamučnih vlakana u režimu skrobljenja.
