“…Such variability in CS physicochemical properties could lead to inconsistent and conflicting reports regarding their biological performance. 181 Chitosan as an auxiliary agent in dyeing and printing processes CS has been widely used as a bio-agent in dyeing processes of textiles with synthetic 182 and natural 183 dyes. Its use offers certain advantages in salt-free dyeing over conventional dyeing techniques: the elimination of toxic and harmful salts, maximum fixation and minimum hydrolysis of dyes and a low volume of water required during the wash off process, that is, significant savings in process costs.…”

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.

“…In the end, the chitosan/cotton fabric composite was prepared by washing and drying. Chitosan improved the dyeability of the cotton reactive dyeing and increased the shade depth of the treated samples . Chitosan powder and acetic acid were added into a cellulose nanocrystalline suspension under heating, and the functional finishing liquid can be obtained by stirring.…”

In recent years, the textile industry has been seeking to develop innovative products. It is a good choice to organically combine materials with superior functional characteristics and commercial textiles to form products with excellent performance. In particular, textiles made of biological functional materials are often beneficial to human health, which is an interesting research direction. As a biopolymer material, chitosan has the advantages of strong availability, low cost, excellent safety, outstanding performance, etc., particularly the antibacterial property, and has broad application prospects in the textile field. This review provides an overview of the latest literature and summarizes recent innovations and state-of-the-art technologies that can add value to textiles. To this end, preparation of chitosan fiber, synthesis of chitosan nanofiber, antibacterial activity of chitosan fiber, antibacterial activity of chitosan nanofiber, etc., will be discussed. Furthermore, the challenges and prospects of chitosan-based materials used in textiles are evaluated. Importantly, this review can not only help researchers understand the development status of antibacterial textiles, but also help researchers discover and solve problems in this field through comparative reading.

“…Recently, ovalbumin was employed to modify the cotton surface to achieve better colorfastness and shade depth with a cochineal natural dye (Giacomini et al, 2020). In another study, chitosan was used to enhance the dyeability of cotton fibers before the application of reactive dyes (Rehman et al, 2020). In a recent study, chitosan was used for surface functionalization of cotton and wool that improved fastness properties and dyeability for reactive, acid and walnut dyes (Haji, 2020).…”

This study is a novel approach toward the development of a chemical-free and sustainable textile dyeing process with minimum environmental risks. Cotton fabrics were cationized with (3-chloro-2-hydroxypropyl) trimethylammonium chloride in four concentrations and subsequently dyed with the black tea extract. Eco-friendly colorant extraction from raw black tea leaves was carried out in aqueous media avoiding the use of hazardous organic solvents. The major coloring components in the black tea extract are polyphenols like theaflavins and thearubigin. Cationized cotton fabrics were dyed in four different shade depths without employing auxiliary chemicals in the dyeing process. For comparison, un-cationized cotton was dyed with the same extract in the same shades. It was observed that un-cationized cotton samples exhibited very low color strength (K/S) values and excellent colorfastness rating. However, the cationized samples showed remarkable enhancement in their color strength with an increase in the concentration of the cationizing agent. Furthermore, colorfastness to washing, rubbing, and perspiration was excellent, but lightfastness was poor. Deep shades (K/S = 8.996) were obtained for cotton sample cationized (20 g/l) and dyed (6%) shades. Thus, the extraction of natural colorants without toxic solvents, economically viable surface modification of cotton, and chemical-free dyeing render the dyeing process cleaner, sustainable, and practicable at an industrial scale. The textile units could easily adopt this approach to regulate a pollution-free dyeing process without modifying their existing infrastructure.
