ПРИМЕНЕНИЕ НАТУРАЛЬНЫХ КРАСИТЕЛЕЙ В ЗОЛЬ-ГЕЛЬ СПОСОБЕ КРАШЕНИЯ ЦЕЛЛЮЛОЗНЫХ ТЕКСТИЛЬНЫХ МАТЕРИАЛОВ
Abstract
In this paper, the modified continuous sol-gel dyeing technology of textile materials with applica-tion of natural vegetable origin dyes and sodium silicate is explained. The method of dyeing, basedon sol-gel process, with optimal value of regimes is proposed, the influence of the regimes on the mechanical properties of cotton fabricsare researched. The colour fastness for wet/dry friction and light stability against artificial weathering were investigated too. Optimal acid concentrations (20 g/l) were established in the second bath and liquid glass (100g/l) in the first bath, as well as the temperature regime of heat treatment. The proposed continuous sol-gel method increases dyeing speed, comparing with periodic dyeing process with natural dyes. Application of this method allows to exceptusing ofenvironmentally harmful components.
