Comparison between naturally colored cotton fabric and white cotton fabric in manner of processes in the dyehouse

Naturally colored cotton gained its popularity again when textile industry focused on ecology and sustainability concerns. one of the most important properties of naturally colored cotton is the avoiding of dyeing process and skipping some pretreatment steps in the dyehouse. so limited chemical treatments will result less usage of water,less waste water,less consumption of chemicals,shorter treatment times,less usage of energy and will add great to the protection of environment besides cost advantageous. in this study a comparison of a natural brown colored cotton knitted fabric with a white one was made in manner of process steps and cost by the data and methods of a dyehouse. calculations were made by taking the treatment steps of the fabrics in the production into account. naturally colored cotton was evaluated by washing and softening steps. the white cotton fabric dyed with the same color of naturally colored cotton in the laboratory and was evaluated by bleaching,dyeing,washing and softening steps. calculations and comparisons were made by taking energy,water,labor,electricity,chemical,auxiliary agent and dyestuff costs into account. as the result all the flowcharts in the dyehouse were evaluated. it was found that treating the naturally colored cotton fabric is 2,9 times less expensive than treating white cotton fabric in the dyehouse.
