Dyeability of Acid Dyes on Wool Fabrics Treated with Pulse Corona Discharge and an Enzyme

Effect of Plasma on Dyeability of Fabrics

The unique physical and chemical characteristics of the plasma environment make it attractive for textile processing. Plasma is an ionized gas, i.e. it contains electrons, ions and neutral atoms and/or molecules. However, not all of the ionized gases used in textile processing will exhibit the properties associated with plasmas, mainly because of their low charge state densities compared to the...

Thermal Properties of Wool Fabrics Treated in Atmospheric Pressure Post-Discharge Plasma Equipment

A plain-weave wool fabric has been treated in a rollto-roll atmospheric pressure, post-discharge plasma equipment at three fabric speeds. The thermal properties of the treated fabric have been investigated by means of an Alambeta instrument. The thermal resistance and thermal diffusivity increased after the plasma treatment while the thermal absorptivity and volumetric heat capacity decreased. ...

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...

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 ...
