Upscaling Millettia laurentii carpentry sawdust into natural dyes: imparting antimicrobial, antioxidant, and UV-protective finish to wool yarns through an ecological and sustainable natural dyeing process

Antimicrobial Activities of Some Natural Dyes and Dyed Wool Yarn

Natural dyes gained increasing attention due to environmental considerations. Many of the dye plants have also medicinal values. This study aimed to evaluate the effect of 25 plants as dyes and their dyed wool yarns against microorganisms. Prokaryotes were found to be more sensitive to dye extracts than eukaryotic microorganisms and dyestuff from Punica granatum, Berberis vulgaris, Agrimoni...

Investigation into the Dyeing of Soybean Fibres with Natural Dyes and their antimicrobial properties

The dyeing behaviour of annually renewable soybean protein fibres with Madder, Weld and Walnut seed husk, natural dyes, were investigated and their possible antimicrobial effects were evaluated. The results obtained from the dyeing of the Madder on the soybean fabric were compared with those on a wool fabric. It was shown that the amount of the amino acid content of the fibre has a great effect...

Dyeing Properties Using Natural Dyes from Rhubarb:

In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...

Dyeing of Textiles with Natural Dyes

Dyeing of Indian wool with reactive dyes

Wool fibres have been chemically modified by reduction I chlorination under acidic pH Ipre-swelling in conc. formic acid prior to their dyeing with indigenous reactive dyes of different molecular configurations to enhance the reactive dye uptake on wool fibre substrate. The pretreatment processes are inexpensive, less harmful and less time consuming as against the use of imported special wool r...
