DEVELOPMENT OF PERMANGANAT ALTERNATIVE EFFECT WASHING CHEMICALS IN DENIM WASHING PROCESSES

Enzyme washing of indigo and sulphur dyed denim

Introduction Denim as a fabric, has received the widest acceptance among all textile products. It has had an incredible influence on consumers both socially and culturally (Paul 2015). This twill cotton fabric usually has warp threads indigo dyed while weft remains plain white. The warp faced fabric therefore looks blue on one side and white on reverse. The warp being ring dyed, creates denim’s...

Effect of Various Washing Process on Properties of Four Way Stretch Denim Fabric

Effect of various washing process on the properties of indigo dyed four-way stretch denim fabric was studied in this research. The different washing techniques (Dark washenzymatic treatment, Medium washenzymatic treatment with pumice stone, Bleach washenzymatic treatment with bleaching powder and pumice stone, Acid Wash-Enzymatic treatment with potassium permanganate and pumice stone) were appl...

Effect of Processing Time and Concentration of Potassium Permanganate on Physico-Mechanical Properties of Denim Jeans During Stone Washing

Three 100% cotton denim jeans were treated with stone acid wash with the variation of processing time (1.5, 2 & 2.5 minutes) and concentration (1.5, 2 & 2.5g/l) of potassium permanganate after typical enzyme bleach wash. Various physical and mechanical properties (Hand feel, Weight, EPI, and PPI, Tensile strength, Shrinkage, Seam strength, Count & stiffness) were investigated before and after e...

Washing effect on superparamagnetic iron oxide nanoparticles.

Much recent research on nanoparticles has occurred in the biomedical area, particularly in the area of superparamagnetic iron oxide nanoparticles (SPIONs); one such area of research is in their use as magnetically directed prodrugs. It has been reported that nanoscale materials exhibit properties different from those of materials in bulk or on a macro scale [1]. Further, an understanding of the...
