The possibility of regulating the properties of cotton fibre from an early stage of its processing, that is, at the stage of separating the fibre from cotton, is always of great interest, but unfortunately, it is not carried out in the conditions of cotton ginning plants. The most important thing is to bring the moisture content to optimal values after drying it before ginning, that is, before separating the fibre from the seed. At the initial stage of research, a composition consisting only of surfactants was proposed to increase the moisture content of the fibre before boiling it. Initially, it was widespread to treat cotton fibre with various aqueous and non-aqueous compositions, both at the spinning stage and in the weaving or spinning stages. The purpose of this study was not only to increase the moisture content of the fibre, but also to improve its other characteristics by treating it with compositions consisting of a water-soluble polymer, polyhydric alcohol, and a surfactant dissolved in water.
