    Non-cellulosic contaminants of raw cotton, either natural by-products of plant development and cultivation or man-induced residues from processing, must be removed prior to successful dyeing and finishing. The natural components of cotton cuticle include lipophilic extractives, like waxes, hydrocarbons, sterols and polyterpenes, protein, ash and hemicelluloses, which mainly consists of pectic substances. Traditionally most of the impurities are removed in scouring by hot alkaline boiling and in successive oxidative bleaching. In this work advanced analytical methods, ESCA, TOF-SIMS and AFM, were used to study the surface chemistry of cotton fabrics along processing, i.e. from raw cotton through scouring to a bleached fabric. Information of atomic composition (ESCA) is combined with those of molecular composition and distribution (TOF-SIMS) on fibre surfaces in order to understand the chemical shifts during different process stages. AFM is used for examination of microstructural changes occured to cotton cell wall during processing. Based on the analytical and structural information generated, possible strategies for new biotechnical methods of cotton pretreatment will be discussed.
