Abstract - The sole sources of fabric dyes in prehistoric times were natural colours made from roots, stems, flowers, leaves, bark, minerals, and vegetables. Throughout history, man has coloured his fabrics using various locally accessible materials. Natural dyeing is a process that employs colourants originating from plants, invertebrates, or minerals. India's skill in vegetable dyes extends back to the Vedic era. Due to the widespread availability and low price of synthetic dyes, the majority of textile dyers and manufacturers have shifted to employing synthetic colourants. These synthetic colourants are created using hazardous chemical processes that put the environment at risk from petrochemical sources. They occasionally explode and are frequently highly carcinogenic and deadly. The aquatic life is harmed by the very poisonous dye effluents that are released into rivers.
Plasma treatment of textiles is a growing function of plasma technology. Using Thierry’s low-pressure systems, plasma treatment of textiles is used to pre-treat fibers to increase wettability which allows for solvent free dyes to absorb and bond very strongly. Also, plasma treatment of textiles is used to coat fabric with a specialized layer with varying characteristics. These surface coatings can have properties such as the ability to repel water or other liquids. This is known as a hydrophobic surface. They can also apply protective coatings to make textiles more durable. This paper presents some relevant scientific overview on dyeing of polyester textile with natural dyes and related issues.
