“…This is because the new bands were more intense after mordanting with tannic acid, as shown in Figure 3. Tannin is very soluble in water, and the hydrolyzable tannins break down via hydrolysis to give gallic acid, a type of phenolic compound [15,16,17]. Therefore, a significant amount of phenolic compounds was chemically attached to the wool fibers through the mordanting process as well.…”

Spent coffee grounds are the byproduct of coffee brewing and are generally discarded as waste. However, spent coffee has high levels of organic compounds that have multiple biological effects, including antibacterial and antioxidant activities. In this light, spent coffee grounds were tested for fabric dyeing to both functionalize as well as color the fabrics. The dyeing solution was prepared by extracting spent coffee grounds collected from a local coffee house by using a manual espresso machine. The spent coffee extract was applied to wool fabrics using a laboratory infrared dyeing machine. After the dyeing process was completed, the fabrics were mordanted with a tannic acid aqueous solution. To optimize the dyeing conditions, the times and temperatures during the process were varied, and the functionalities and other properties including color and strength of the wool fabrics dyed with the spent coffee extract were investigated. The wool fabrics dyed with the spent coffee extract were significantly colored, and the color withstands the effect of washing and light exposure. Moreover, the dyeing process with the spent coffee extract and the mordanting process with tannic acid gave the wool fabrics antibacterial and antioxidant properties.

“…Like in the case of quaternary ammonium compounds, functional antimicrobial property of mixture of chitosan and silver nanoparticles has been reported by researchers to be better than that of individual agent. Therefore, coating textile fibers with mixture of chitosan and silver nanoparticles imparts very good antimicrobial property onto them [4]. Chitosan or chitosan/Ag + coated textile materials are very good as surgical garments, gloves and face masks.…”

“…Bhuiyan et al [3] reported Lawsonia inermis L dyed jute fabric to have a good microbial inhibition and when surface modified with chitosan the percentage inhibition greatly improved. Hong [4] observed that tannin mordanted spent coffee grounds dyed wool fabric inhibited above 95% of microbial growth. Jabar et al [1] reported that 1, 3-bis[(furan-2-l) methylene]thiourea functional dyed wool and cotton fabrics have excellent fungi inhibition.…”

Textiles for Functional Applications

Most textile materials are potential substrates for microbial growth. In order to make textile materials suitable as functional materials, the microbial growth must be reduced to the barest minimum or quenched due to their undesirable effects; such as offensive odor, discoloration, degradation, mechanical strength reduction etc. Chemical finishing of textile materials (such as application of silver nanoparticles, quaternary ammonium compounds, chitosan, some synthetic and natural dyes to mention a few) is capable of imparting this functional property among others to the textiles. Although, mechanism of antimicrobial activities of treated textiles is yet to be clearly defined, but in most cases, antimicrobial action of treated textiles usually occurs through interaction of cation in antimicrobial agents with anionic charged microbial cell wall. Antimicrobial treated textiles are usually less prone to offensive odor, discoloration, deteriorating mechanical properties and make the consumers free of skin problems. In fact, they can be used as cheap materials for production of hospital gowns, hand gloves and face masks for containing microorganism borne diseases, such as the current Covid-19 pandemic.

“…Tannins are generally divided into two groups (Figures 8 and 9): Functional Properties of Natural Dyed Textiles DOI: http://dx.doi.org /10.5772/intechopen.88933 Tannin is considered as a protective agent against microbes and UV rays. Antimicrobial and antioxidant properties of dyed wool fabric were observed to have improved after application of tannin [90].…”

Recently, due to harmful effect of climate change and other environmental concerns, the interest towards natural dyes has gained momentum. Presently in this high technological era, only aesthetic appeal of natural dyes could not get full attention of consumers. A consumer is attracted towards a type of product which is not only aesthetic but also have some functional properties. Hence considering this functional aspect, various researches are being carried out to find out the new dimensions of natural dyes. Colours and other functional properties can be achieved by various synthetic agents, but the exploration of new functional properties of natural dyes would be beneficial and relevant for the present as well as for the future. This chapter compiles all functional aspects of natural dyes which are related to adding functional properties such as antimicrobial, UV protection, insect repellent, etc. to textiles which can protect the human being from various kinds of harmful effects of surroundings such as UV radiation, microbes, bacteria and other harmful insects. This chapter will not only deal with available methods for analysis of these functional properties of natural dyes but also explore the reason for functional properties of natural dyes.
