The Natural Dyes as Applied to Wool

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...

Dyeing Wool with Metal-free Dyes – The Use of Sodium Borohydride for the Application of Vat Dyes to Wool

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...

Exploring and exploiting plants extracts as the natural dyes/antimicrobials in textiles processing

The large number of publications in the field of extraction, purification, modification, and process optimization of natural dyes and their application on textiles demonstrates the revival of natural dyes on textile coloration. The use of natural dyes is growing in popularity because of the quality of the natural dyestuff obtained, the environmental compatibility of the dyes and the substantial...

Natural Wool Fabrics in Physiotherapy

Prevention of heat loss, thermal insulation and heat treatment play an important role in physiotherapy. For example, peripheral vascular disease associated with metabolic diseases (e.g., diabetes, arteriosclerosis), arthritis, paresis and paralysis of peripheral nerves all require interventions involving heat therapy. Wool products such as garment linings, shoulder-straps, knee pads and lumber ...
