VARIOUS wet processing operations of textiles from the initial preparatory process to final finished clothes are now focused for green technology. Several conventional non-ecofriendly chemicals are being replaced by natural based products that are safe to the environment and health during manufacturing and usage. Natural dyes were used instead of synthetic dyes due to environmental conditions. Natural dyes are very important for textiles as well as to replace synthetic dyes, because of non-polluting, non-carcinogenic and eco-friendly. Silk is the lightest, thinnest and softest natural fiber and has many applications in the textile field. In the present work the silk fabric pretreated with PEG then dyed with two different natural dyes, the fabric then compared with those dyed with natural dyes only and with those with dyes and mordents. protective properties such as UV- blocking give a remarkable improvement in UPF values. the antibacterial reduction percentage was also enhanced. significant enhancement in dyeability values K//S values are demonstrated. Also, the mixture with PEG showed good tensile strength, wettability Enhancement and also crease recovery angles.
