This article presents a study regarding the use of natural dyes in the dyeing of silk. Furthermore, the study explores the possibilities of extracting dyes from different parts of plats and to optimize various dyeing variables of dyes for dyeing silk. Dyes can be extracted from Jatropha integerrima, Lantana camara, Hamelia patens, Euphorbia pulcherrima, Berberis vulgaris, and Juglans regia. The process of obtaining dyes from natural sources is discussed in the article. Furthermore, there are several colors obtained on silk with different mordants and mordanting methods. Finally, a standard recipe was optimized for dyeing silk with each dye source.

The article focuses on a study which examined the color fastness properties of Semul dyed silk fabrics by using metallic mordants. A description of the semul tree is provided. White mulberry silk was used in the study. Two Bureau of Indian Standards were used to test the color fastness of dyed samples, namely, color fastness to washing test and color fastness to sunlight test. The role of alum in adding brilliance to the color on silk and wool without damaging the fiber is revealed.

The article focuses on a study that attempted to dye silk samples with a Poinsettia leaf dye and examined the colorfastness of the dyed material. The silk samples were degummed prior to dyeing to make them free from sericin. The processing of the Poinsettia dye involved no toxic chemicals. The dyed silk samples were tested for colorfastness against light, washing, crocking and perspiration.

This article describes the use of Lantana flowers in the dyeing of silk. Acidic, alkaline and aqueous medium were used for extraction of dye. Acidic medium was selected as it gave good shades on silk. The absorption of silk increased with the increase in concentration of dye. After that, the absorption decreases with the increase in the concentration of dye. The maximum absorption was obtained on the silk sample when Lantana dye solution was extracted for 90 minutes followed by 120, 150, 60 and 30 minutes respectively. The absorption of silk increased with the increase in the dyeing time from 30-75 minutes. Maximum absorption was found when dyeing was continued for 75 minutes. After, it decreases with the increase in the dyeing time to 90 minutes. In order to select the best method of mordanting, silk samples were mordanted by three methods. The method of mordanting was selected for different mordants on the basis of visual evaluation. It is evident that post mordanting method showed highest marks for all the natural and metallic mordants thus selected as best for dyeing of silk with Lantana flowers dye. Lantana flowers produced colours that are gentle, soft, and subtle. Since the processing involve no toxic chemicals, it will give good opportunity to use this dye in the industry.
