In this study, the dyeing procedure of wool fibers withPrangos ferulaceawas evaluated and optimized by response surface methodology (RSM). Using this method, the quantitive relationship between dye concentration ofPrangos ferulacea, mordant concentration, dyeing temperature, and dyeing time on the dyeing procedure was investigated. The effect of these variables as well as plasma pretreatment was examined on the color strength of dyed samples. Finally, the fastness characteristic of dye sampled at proposed optimized condition was reported. The obtained results indicate that the presence of mordant improved the fastness properties and dyes uptake of wool fibers.

In printing and resin finishing of cotton fabrics, the curing step is involved twice, firstly for fixation of reactive dye and secondly for the fixation of resin for proper cross-linking. In developing country like Pakistan, where cotton is a major portion of textile exports, the elimination of one fixation stage is economical and advantageous. This study dealt with the simultaneous fixation of wrinkle-free finish (resin) and reactive dye printing for cost effectiveness. The processed route of treatment imparted a maximum dry crease recovery angle of 230° and color strength up to 89.89%. The produced fabrics were characterized using crocking fastness (dry and wet), color strength sum %, color fastness to laundry, crease recovery angle, and wrinkle recovery by appearance method. Response surface optimizer gave good composite desirability value (0.08300) with color strength % of up to 73.73 and dry crease recovery angle up to 218°.

Wool Dyeing

In this study, wool fibers were dyed using the Juglansregiabark as a new source of natural dye. Alum was used as mordant. Response surface methodology and D-optimal design were employed to study and optimize the dyeing procedure with the aim of obtaining the maximum color value after dyeing with aqueous extract of Juglansregiabark. The results showed that the color value of the dyed fibers was increased by increasing the dyeing time and temperature and decreased by increasing the dyebath pH value. There was an optimum value of around 6 % owf for mordant concentration. The optimal condition for obtaining the highest color value was as follows: dyebath pH: 6, alum concentration: 6.24 % owf, dyeing temperature: 90 ºC, and dyeing time: 90 min.
