Abstract
The study concentrates on the comparative nature of the denim cloth manufactured using 100% cotton as well as hemp cotton blends concerning the dimensional stability, washing performance and mechanical properties. It is a fiber, which is found naturally and hence it has been used widely since it is potent and it softens on the skin. Hemp fibers are tree-like in length. This means, as a result, they possess many eco-friendly features, including reduced water requirements, omitting pesticides as a result of improved soil health. The hemp fibers are also mixed with cotton so as to provide strength in the fabric as well as environmental friendliness. The studies take into consideration the density characteristics of each kind of cloth (i.e. what they are made of, what and how they are woven and what chemicals are used to make them and what is its impact on dimensional stability). The mechanical strength of the fabric after a variety of different denim washing procedures are tested and evaluated to give an idea of how these processes interfere with shrinkage, tensile strength, flexibility, weight and the appearance. Though the studies exist on properties of denims, not much research work has been conducted in relation to physical qualities in general with regard to cotton and hemp/cotton blend denim materials. The gap is bridged by a well-assigned implementation of the present study itself and, consequently, it adds to the broader scope of the field of textile science. The findings would offer some information that would assist the manufacturers of fabric, garment and accessories and designers to improve on the use of hemp-cotton mixes in manufacturing of sustainable denim products of better quality. This research would offer information on dimensional stability of denim with different blend ratios and their mechanical properties. The results indicate how much further research is required to determine most appropriate ways of balancing between environmental consequences and technical performance, to enable adaptation in an evolving textiles environment and market.
