| Popis: | Currently, synthetic dyes are used for dyeing textile materials. These dyes are characterized by a wide range of colors and low production cost. However, they pose environmental risks, since they are not biodegradable, cause pollution of surface water sources, and also create disposal problems. A viable solution to these issues is the use of natural dyes. A technology has been proposed for dyeing textile materials made from natural fibers (cotton, linen, wool) using the underground part of the Potentilla Erecta plant. It is known that the color intensity of textile material during the dyeing process depends on the concentration of the dye in the working bath. This concentration can be increased by augmenting the mass of plant materials in the dyeing bath, but this will lead to a greater material intensity of the process. The purpose of the work is to select rational parameters for the preparation of lignified plant raw materials (cinquefoil roots) for extraction, ensuring maximum output of the dye into the working bath with minimal consumption of raw materials. Research has been carried out to select the optimal particle size of raw materials and rational parameters for cavitation treatment of plant roots, ensuring the best extraction of the dye into the working solution. It has been determined that during ultrasonic treatment, in order to minimize the reflection coefficient of sound energy, enhance the process of dissolution and leaching of the dye from destroyed cells, the particle size of the raw material should be no more than 1 mm, the generator power shall not exceed 70 W, and the treatment shall last 50 minutes. The research results can be recommended for the preparation of woody parts of plants of other species used in the technology of dyeing textile materials. |
