Development of technology for textile materials with special properties

Due to the increasing amount of oily wastewater accompanying the development of industry and society, as well as frequent accidental oil spills, there is a growing need for functional materials that absorb oil and separate oil and water. Various approaches have been used to manufacture such functional materials. The creation of new oil-absorbing materials with high selectivity towards water and oil by increasing hydrophobicity and oleophilicity is promising. In this paper, the issue of obtaining a composition for making textile materials hydrophobic and oleophilic is considered. The purpose of this work is to develop innovative textile materials designed to purify water resources from oil pollution and evaluate the effectiveness and safety of materials. The practical significance of the work lies in the need to develop a textile material that will surpass other materials in the efficiency of cleaning oil pollution, environmental friendliness and cost. Sodium oleate, liquid glass and citric acid were used for this purpose. The materials were treated with a ready-made solution, then dried for 10 minutes at 120 ° C and processed in a thermal press at 150 ° C for thermal fixation. 100% cotton fabric article 1030 and synthetic fabric 81421 premier Standard 250 (65% PE, 35% cotton) were used as the object of the study. New materials have been developed to ensure effective separation of oil from water, the physico-chemical foundations of the new method have been improved in order to give textile materials hydrophobic and at the same time oleophilic properties for effective purification of water resources from oil pollution. It has been established that new materials can be effectively used for high-quality water purification from oil pollution.
