Resistance of textile materials treated with flame retardants based on electroerosive Aluminum hydroxide powder to physical and chemical influences

The purpose of this work was to study the stability of products made from various textile materials, including cotton and viscose, exposed to friction and washing in various aggressive environments.Methods. The resistance of cotton and viscose fabrics treated with flame retardants based on electroerosive Aluminum hydroxide powder to washing was studied on a mechanical device, which includes a water bath with a rotating shaft. To test the resistance of fabrics to friction, 18x8 cm samples were prepared. Before testing the tissue samples, they were impregnated with a new flame retardant based on electroerosive Aluminum hydroxide powder and compared with a new dry tissue sample. The tissue samples were subjected to several washing cycles. An increase in the number of washing cycles led to the loss of part of the flame-retardant impregnation and a decrease in the burning time of the treated fabric.Results. According to the results of the conducted studies, it was found that the resistance of fabrics with flame-retardant impregnation to physico-chemical influences depends on the concentration of powder and the composition of the textile material. At the same time, a flame-retardant impregnation based on electroerosive Aluminum hydroxide (EEGA) is obtained from Aluminum metal waste by an environmentally friendly and low-energy-intensive method of electroerosive dispersion. The protective functions of the new flame retardant are manifested as follows: under the influence of high temperatures, the EEG releases crystallizing moisture (steam) and thereby lowers the temperature below the ignition point. In addition, the resulting water vapor prevents oxygen from entering the combustion zone. Gorenje.
