“…Cotton garments, which are often used in summer, cannot provide sufficient protection against solar radiation. Thus the treatment with synthesized UV absorbers containing reactive groups must be carried out [38,39]. Some reports have demonstrated that natural dyes can also impart UV protection effects to cotton textiles [40,41].…”

Cotton has the shortcomings of having no antibacterial, antioxidant and ultraviolet (UV) protection properties, which are of great importance for health protection purposes. In the present study, grape seed extract (GSE) mainly composed of proanthocyanins (tannins) was employed to simultaneously import pale colors and the three aforementioned functions to cotton fabric. The tests on the application conditions of GSE showed that pH and GSE concentration had great impact on the color depth of cotton fabric, and the color hue of dyed fabric could be controlled in the absence of pH regulators due to the weakly acidic nature of GSE solution. The fabric dyed with 10%owf (on the weight of fabric) GSE exhibited an excellent inhibition effect towards Escherichia coli, whereas the one dyed with 20%owf GSE had high antioxidant activity of 97%. The fabric dyed with 5%owf GSE offered excellent UV protection. This study reveals that GSE can be used as a functional finishing agent for health protection in cotton textiles in addition to coloration capability.

“…It is indicated in the literature that dark coloured fabrics with high K/S values transmit less UV radiation than lighter shaded fabrics with lower K/S values [36][37][38][39] e reason why one or the other natural dye gives higher or lower UPF values to the cotton samples is most likely connected to the chemical structure of dye and its ability to absorb light near UV region than to its dyeing properties. is conclusion is supported by the fact that textiles nished with organic UV absorbers that are colourless compounds that absorb in wavelength from 280 to 400 nm have excellent UV protective properties [40,41]. Although dyeing cotton samples with pomegranate peel extract gave remarkable UPF results, the e ect is not stable to washing (Figures 9 and 10).…”

Dyeing with natural dyes extracted from curcuma, green tea, avocado seed, pomegranate peel and horse chestnut bark was studied to evaluate the dyeability and ultraviolet (UV) blocking properties of raw and bleached/mercerised cotton fabrics. 20 g/l of powdered plant material was extracted in distilled water and used as a dyeing bath. No mordants were used to obtain ecologically friendly fi nishing. The colour of samples was measured on a refl ectance spectrophotometer, while UV-blocking properties were analysed with UV-Vis spectrophotometer. The results showed that dyeing increased UV protection factor (UPF) to all samples, however much higher UPF values were measured for the dyed raw cotton samples. The highest UPF values were obtained on both cotton fabrics dyed with pomegranate peel and green tea extracts, giving them excellent protective properties (UPF 50+). The lowest UPF values were obtained by dyeing cotton with avocado seed extract and curcumin. Dyeing with selected dyes is not stable to washing, so the UV-blocking properties worsen after repetitive washing. However, raw cotton samples retain their very good UVblocking properties, while bleached/mercerised cotton fabrics do not provide even satisfactory UV-blocking properties. No correlation between CIE L*a*b*, K/S and UPF values were found. Keywords: UV protection, dyeing, natural dyes, cotton Izvleček

People are paying increasing attention to environmental protection and prefer products to be manufactured and consumed in an environmentally friendly way. These are the main trends likely to persist in the near future. In the past two decades, academic research on environmentally friendly coloration has proliferated significantly. In this study, the current status of environmentally friendly coloration research and the future research trends are reviewed systematically, covering the literature from 1995 to 2014. The environmentally friendly coloration literature is classified by objectives into four categories: ingredient preparation; coloration process; wash‐off process; reuse. After reviewing the accumulated knowledge of coloration, future directions of ecological coloration development are discussed.
