Abstract

Natural dyes have better bio degradability and generally have higher compatibility with the environment. They are non toxic, non-allergic to skin, non-carcinogenic, easily available and renewable. Color fastness is the resistance of a material to change any of its color characteristics or extent of transfer of its colorants to adjacent white materials in touch. Generally light fastness, wash fastness and rub fastness are considered for textile fibers. The outer skin of onion contains different phytochemicals which are responsible for giving colour, antimicrobial and antioxidant properties to the fabric. In this study, natural colourants were extracted using different solvents. The dye potential of the colourants obtained from the onion skin dye was evaluated by colouring cotton fabric. Bio mordanting of cotton fabric was done by using biopolymer before dyeing to improve the dyeabilty of cotton fabric with natural dye. L*, a*, b*, C*and H* values and k/s value was studied. Study about the different fastness tests were undertaken by using standard test methods. The chitosan treated cotton fabric showed higher k/s value. Good light fastness, wash fastness, rubbing fastness and perspiration fastness. From an ecological point of view, dyeing of cotton fabric with natural dye with bio mordanting may better alternative to conventional mordanting with chemicals.

Abstract

Textile finishing is a diversified sector due to the processed raw materials, manufacturing technique and finalized products. Natural finishes comprises of those substances that are obtained trom plants and animals. Natural finishes have many advantages such as non toxic, non irritant, biodegradable, cost etfective, easy availability, etc. now days consumers are more aware and conscious about health, hygiene and environment so they are looking for natural product having potential like synthetic products to impart antimicrobial, aroma finish to textile products. So there is need to screen the present of phytochemicals in the plant extract because it plays an important role in imparting antibacterial, antifungal and antioxidant property to textile material and also helps in dyeing and printing of textile material. In the present study phytochemical analysis of peepal leaves was done to know the presence of different phytochemical. It was found that it showed the presence of alkaloids, anthraquinone, phenol, saponins, steroids and tannins was observed in both mediums of extraction.
