Studies on effect of washing cycles over Natural Chrome and Lustre of Muga, Tasar and Nistari silk fabrics

摘要

The study of the natural pigmentation and its wash fastness properties of natural coloured silk involves through investigation and quantification of fading property of Tasar, Muga & Nistari silk fabrics. The natural colouring matter of silk can therefore be roughly divided into yellow, green and brown pigments. An effort is made to find the fading phenomena of natural colourant of Tasar, Muga & Nistari fabrics during washing is undertaken through experimentations. The wash fastness of Muga and Tasar has been found to be good until 50 washes where as the fastness of Nistari silk is good till 10 washes.
