Non-food applications of natural dyes extracted from agro-food residues: A critical review

Chitosan grafting via one-enzyme double catalysis: An effective approach for improving performance of wool

The objective of this research is to optimize the dyeing parameters for cotton fabric with natural dyestuff extracted from Dactylopius coccus. In order to obtain purple hue, the influence of dyeing process conditions i.e. dye bath pH, concentration of dyestuff, and the addition of electrolyte has been studied. Additionally, potassium aluminium sulfate dodecahydrate and iron (II) sulfate heptahydrate were used as mordants on cotton fabrics in order to obtain coloration of specific purple hue. Colorimetric data and fastness properties of the dyed samples have been analyzed. Results indicate that the dyeing parameters as well as pre-treatment has a significant influence on the obtained purple shades and fastness properties.

Optimization of Dyeing Process of Cotton Fabric with Cochineal Dye

Chitosan is a biopolymer obtained from deacetylation of the abundant natural chitin polymer. It has found its use in many applications due to its unique solubility as well as chemical and biological properties. In addition to its biodegradability and biocompatibility, it has many reactive amino side groups that offer the possibilities of chemical modification and formation of a large variety of beneficial derivatives. Numerous researchers have published works outlining the physical and chemical properties of chitosan, as well as its use in several industries, such as medical, environmental and food. Due to its excellent absorption and biological properties, chitosan present a myriad of opportunities in eco-friendly textile processes. Chitosan is able to confer antimicrobial, antiviral, anti-odor and other biological activities to textile fibers and fabrics. In this review, the first part is dedicated to developing the physio-chemical and biological characteristics of chitosan. Then, we present chitosan applications in the textile industry over the past decade. Literature works on chitosan usage along with different textile production steps (fiber formation, functional treatments, dyeing and effluent treatment) are extensively discussed.
