Abstract. In recent years, the issue of replacing formaldehyde-containing preparations used in the final finishing of cotton fabrics with compounds without formaldehyde or with a low content of it has become particularly relevant. The paper is devoted to the study of the possibility of using various textile auxiliaries for low-crease finishing of cotton fabric. The possibility of using acetone-formaldehyde resin as a low-formaldehyde binder instead of traditionally used preparations has been shown. The fabric finished according to the recommended technology with the use of ACF-resin, in comparison with the traditional one, has a lower weight gain and wash ability of the dressing, a higher crease resistance and tensile strength. The effectiveness of the use of phosphorus-containing alkaline earth metals as catalysts for the crosslinking of cellulose macromolecules in the compositions of the sizing agent, both with polycarboxylic acids and with a low formaldehyde-containing ACF-resin preparation, has been established. An increase of total wrinkle recovery angle (WRA) of cotton fabric has been achieved more than 200 degrees at a concentration of crosslinking catalysts equal to 4%. The use of polycarboxylic acids, in particular 1,2,3,4-butanetetracarboxylic and maleic acids, together with phosphorus-containing alkaline earth metal catalysts, leads to the formation of additional strong covalent bonds between cellulose fiber macromolecules, which further contributes to the stabilization of the system by increasing the proportion of elastic elastic deformation.
Key words. cotton fabric, crease-resistant finish, catalyst, cross-linking, total wrinkle recovery angle, breaking load.
