Our increasing awareness of environmental protection has been driving us to ecological considerations. In the textile industry sparkling "green" concepts in the textile market fall into the mainstream efforts following the 'ecology' trend, which can thus merchandise the opportunity to tie in with Ecology. Campaigns and movements emphasising that the textile has been produced from environmentally friendly materials/means become a selling point in terms of marketing strategy. In fact, "green" concept can further be developed with the help of "natural dyes". To yield an environmental production by minimising the production and accumulation of waste products and pollutants, traditional production methods such as the use of commonly accepted chemical substances in preparation, dyeing, printing and finishing of fabrics and yarns must be changed. By integrating "natural dyes", the production of which is based on vegetable dyes and mostly natural auxiliaries for preparation and finishing, the anout of harmful by-=products can be lessened to a minimum. In the present study, the optimisation of using simulated waste Chinese Tea such as waste Lung Ching tea in dyeing wool fabrics was investigated. A multivariate approach was used for the experimental design that allows for a simultaneous variation of all the intervening variables. The central composition design of multivariate Response Surface Method was the techniques used for study the optimisation parameters. The data was collected to formulate a mathematical model to predict the dyeing uptake in using natural Lung Ching tea dye on wool fabric.
