ABSTRACT
This article presents method and results of study on technology of flame retardant and wafer repellent for cotton fabric used for civil and special purposes In this work we of chemical substances for the treatment, and the suitable ones for cotton fabnc treatment are chosen We study influence (^
some main parameters, a heating temperature, a time of heating and concentration of eros-linldiig substance on the fabric properties, such as its flame time, water repellent and tensile strenght afterthe treatment and after 5 washing cycles. In this work, the Box-Wilson method and the Design Expert 6.0 software are used to design the experiment and to treat the expenmental data. The expenment regression functions between three parameters and the flame time, water repellent and fens/te strength of the fabirc after treatment and after 5 washing cycles were established From that, the optimal technological parameters were determined, which ensure that the treated fabnc has good flame retardant. water repellent and mechanical properties.
