Level and Magnitudes of Shade Deviation and Subsequent Environmental Challenges of Turquoise Colorants

Abstract

 Reactive dyes for turquoise hue have definite properties of larger structure results shade deviation between batches in knit fabric dyeing. Dyeing technique of turquoise color as well as comprehensive analysis on deviations on shade and physico-chemical properties concerning batches of dyed knitted fabric with respective utility consumption has been investigated in this research. To obtain the level and magnitudes of deviation, three batches of cotton knitted fabric dyed with turquoise color having same recipe as well as same condition were examined. Ailment of shade on different stage of knit dyeing with turquoise color also reported. Process chemicals, parameters, process flow and visual analysis on light box as well as spectrophotometer analysis of all three samples was supplemented. In addition, physical and chemical test of sample dyed fabric such as color fastness to wash, color fastness to rubbing was tested under the ISO 3, ISO 105 E04, and ISO- 105-AO3 method respectively. Besides color strength as well as utility and time consumption of each batch have an inclusive investigation. After widespread analysis of the samples a considerable shade deviation has been testified which lead to reprocessing. As a result, production rate becomes lower, fabrics damage, production cost, chemicals and water consumption become higher, which upshots ruthless impact on environment through higher pollutants generation
