The role of natural dyes in the UV protection of fabrics made of vegetable fibres

Ecological dyeing of Woolen yarn with Adhatoda vasica natural dye in the presence of biomordants as an alternative copartner to metal mordants

“…Recently discovered properties of natural dyes such as insect repellent [1], deodorizing [2], flame retardant [3], UV protection [4], fluorescence [5,6], and antimicrobial activity [7][8][9], besides being biocompatible, biodegradable, renewable, and nontoxic have revolutionized all industrial sectors especially textile industry for producing more appealing and highly functional value-added textiles [10,11]. This is a result of ecological concerns related with the use of 118 of the azo and benzidine synthetic dyes with 24 carcinogenic aromatic amines as their primary photolytic degradation products, which have motivated researchers all over the globe to explore new eco-friendly substitutes for minimizing their negative environmental impacts [12].…”

Effect of Mordant on UV Protection and Antimicrobial Activity of Cotton, Wool, Silk and Nylon Fabrics Dyed with Some Natural Dyes

“…The washing fastness of the non-mordanted fabrics (control) and the dyed mordanted fabrics has no significant change and they have shown good to excellent results, except dyed nylon fabric with pomegranate extract (control) [6]. The light fastness data of dyed mordanted fabrics with pomegranate extract give very good results which is better than the dyed fabrics with pomegranate only (control).…”

“…UV-A causes little noticeable reaction on the skin but it reduces the immunological response of skin cells. UV-B is the most responsible for the growth of skin cancers [6][7][8][9][10][11][12][13]. In addition to the importance of avoiding exposure of human-skin to solar UV radiation, the dyed clothes are more UV protected than undyed ones [14][15][16][17].…”

Making of Natural Dyeing Scarves by Tie-Dyeing Technique

“…Natural dyes have also been used for printing and dye-sensititized solar cells [4]. It is reported that some natural dyes not only dye with unique and elegant colors, but also provide antibacterial, deodorizing and UV protective functions to fabrics [5]. With the level of interest rising about accessory today, scarf get out of ancilary role of clothes and its proportion is gradually expending to a leading position where it leads the overall atmosphere of fashion.…”
