Preparation of cotton fabric for dyeing.
In order to prepare the fabric, a washing bath was prepared consisting of 550.0 cm3 of deionized water, 1.1 g of Pretepon G, and 9.3 cm3 of aqueous ammonia hydroxide at a concentration of 25%. The washing process was carried out at room temperature for 10 min. Washed and dried fabrics were cut into 5.0 × 5.0 cm sheets for use in the dying process and as reference material. The prepared cotton fabric was analyzed with scanning electron microscopy (SEM) to determine its texture. SEM analysis were performed using 1430 VP microscope by LEO Electron Microscopy Ltd.
