“…In exhaust dyeing technique, the dyes are transfered from dyebath into the fibre polymer by adsorption and absorption and finally get fixed into polymer network. On the other hand, padding (mostly pad-dry-cure in natural dyeing) has some distinct advantages over exhaust method (Maulik et al, 2011;Syamili et al, 2012).…”

“…The mordant applications enhanced the lightfastness and wash fastness properties, providing deeper shades with less dulling and darkening than the control (Deo and Desai, 1999). Syamili et al (2012)used tea extracts to develop complexes with copper for application as antibacterial finishes on cotton. This was an attempt to develop an eco-friendly textile finish using natural polyphenols; however, the involvement of heavy metals rendered the process unsustainable.…”

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.

“…Furthermore, results showed that, even if some reductions in antibacterial activity occurred after laundering, capsaicin remained in the structure of the fibers [ 157 ]. Green Tea [ Camellia sinensis (L.) Kuntze] extract, together with citric acid as a cross-linker, was used to confer antibacterial features to cotton fabrics using a pad–dry–cure method with good antimicrobial properties of treated items [ 158 ]. Moreover, wool textiles were dyed with green tea extract with the help of aluminum sulfate, and AATCC 100-1993 method was used to test the antibacterial activity of treated fabrics.…”

Bacterial colonization of surfaces is the leading cause of deterioration and contaminations. Fouling and bacterial settlement led to damaged coatings, allowing microorganisms to fracture and reach the inner section. Therefore, effective treatment of surface damaged material is helpful to detach bio-settlement from the surface and prevent deterioration. Moreover, surface coatings can withdraw biofouling and bacterial colonization due to inherent biomaterial characteristics, such as superhydrophobicity, avoiding bacterial resistance. Fouling was a past problem, yet its untargeted toxicity led to critical environmental concerns, and its use became forbidden. As a response, research shifted focus approaching a biocompatible alternative such as exciting developments in antifouling and antibacterial solutions and assessing their antifouling and antibacterial performance and practical feasibility. This review introduces state-of-the-art antifouling and antibacterial materials and solutions for several applications. In particular, this paper focuses on antibacterial and antifouling agents for concrete and cultural heritage conservation, antifouling sol–gel-based coatings for filtration membrane technology, and marine protection and textile materials for biomedicine. In addition, this review discusses the innovative synthesis technologies of antibacterial and antifouling solutions and the consequent socio-economic implications. The synthesis and the related physico-chemical characteristics of each solution are discussed. In addition, several characterization techniques and different parameters that influence the surface finishing coatings deposition were also described.
