A substantial contribution to environmental contamination are the different procedures employed in the textile sector, so there are several initiatives to decrease pollution via using natural dyes or other natural auxiliaries in the textile wetting processes such as:-Discharge printing of polyester fabric using Thiourea Dioxide, Discharge printing of cotton and Silk fabrics dyed by turmeric natural dye, Discharge Printing of Denim Using Potassium Permanganate as Oxidative Agent, Application of Resist Printing using Flour of Wild Taro as a natural resist printing agent for Printing of Silk Fabric and resist printing of cotton fabrics using chitosan as a resist agent.
Textile printing is the process of applying ink to textile surfaces using specialized printing processes and machines. The most direct printing techniques used are discussed. Block printing is one of the ancient art forms in India that has been passed down through generations. Flat and rotary screen printing which are capable of extremely high rates of production due to their adaptability. Burn out printing which gives us distinguished designs and Digital printing which is one of the most exciting advances in the manufacturing and textile sectors. Indirect printing such as resist printing and discharge printing which attracts attention as its pattern appear with diverse colours on a dark background. The variety of designs that can be created using the discharge printing technique polluted the environment due to the toxic reducing and oxidizing agent used so they have been substituted with eco-friendly enzymes.
T HE use of natural colors creates no problems for waste disposal and can provide naturally dyed fabrics. Dyes may be derived from natural resources since old times. And The revival of sustainable plant-based dyes now a day is becoming the demand for the global community in all fields.so in this review, we discuss the application of natural plant extracts such as peanutpod which usedin the dyeing of cotton fabric and using olive tree leaves and its extraction to dye cotton fabric and dyeing wool using henna extraction with the use of chitosan pretreatment instead of mordanting and also extract new natural mordant from oak and uses it In the dyeing of wool fabric.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
