Technology for obtaining dyes from Rhamnus L.

Natural dye plants of Azerbaijan occupy a vast territory, from plains to subalpine and alpine meadows. Although there are many natural dyes, not all of them are used in dyeing. Depending on the geographical zones, dye plants are used in each zone. In Karabakh, which is engaged in gardening, fruit trees occupy the main place in this area. Residents of carpet districts located in the forest zone used leaves and firewood of trees growing in the forest, such as oak, elm, prickly plum, birch, alder, buckthorn, dogwood, hawthorn, currant, etc. Taking into account the influence of the time of collecting dye plants on the quality of the dye, each dye plant was collected at a certain time. It is recommended to collect leaves and young shoots of Rhamnus L. in late summer, and stems - in autumn. The work presents the main method of dyeing wool with Rhamnus L. extract.
