Abstract
The present research was conducted during the year 2014-16 with the objectives to explore the spinning possibilities by blending University of Agricultural Sciences (UAS) sheep breed wool with man-made fibre and natural fibre, to find out the physical properties of blended yarns, to develop plain woven blended fabrics, to assess the mechanical, functional properties and to enumerate the cost of production of blended fabrics. To enhance the optimum utilization of UAS sheep breed fleece, the scoured wool fibres were blended with acrylic, r-PET and jute in varied blend proportions i.e., 70/30, 60/40 and 50/50 respectively through sandwich technique. Pure and blended yarns were spun on hand charaka and friction spinning machine and subjected to physical properties viz., yarn count, yarn twist, single yarn strength, elongation and yarn evenness. It was revealed that the friction-spun blended yarns exhibited improved fineness, greater twist, elongation and evenness than the hand-spun yarns. However, higher strength was seen in the hand-spun yarns compared to friction-spun yarns. Based on the strength and total yarn imperfections, blended yarns of hand-spun wool/ r-PET (70/30) and friction-spun wool/ jute (60/40) and pure wool yarn from each spinning system were selected for production of twill woven union fabrics. Four types of union fabrics were woven on handloom using 2/20s cotton as warp and blended yarns as weft and subjected to mechanical and functional properties. The hand-spun union fabrics exhibited heavier, thicker, greater cloth crease recovery, higher abrasion resistance and thermal insulation. The friction-spun union fabrics possessed higher tensile strength, elongation, drapability, air permeability and resistance to pilling. The production cost of hand-spun union fabrics (control sample - Rs. 346.78/ meter and cotton x wool/ r-PET (70/30) Rs. 332.56/ meter) were found to be more compared to friction-spun union fabrics (control sample - Rs. 272.78/ meter and cotton x wool/ jute (60/40) - Rs. 278.94 / meter).
