| description | An attempt was made to compare the combined desirability value for a treated and untreated handloom fabric using machine-spun and hand-spun blended yarns as weft. The experimental plan included the preparation of both hand-spun and machine-spun yarns at different blend compositions according to a mixture design prepared on Design-Expert software, followed by the preparation of fabric on a handloom. The dissolution of one component using a suitable chemical treatment was then performed on both fabrics made from handspun and machine-spun yarn by taking into account an expected significant change in the arrangement of constituent fibres that ultimately enhance performance in terms of the thermo-physiological behaviour of fabrics. All properties viz air permeability, compressibility, thermal resistance, water vapour permeability, bending rigidity and drying capacity showed significant differences for both type of fabrics. Fabrics with hand-spun yarn as a weft demonstrated higher values of thermal resistance, compressibility, water vapour permeability and drying capacity due to the voluminous and soft structure of hand-spun yarn compared to fabric with machine-spun yarn as a weft. In general, after the dissolution of the polyvinyl alcohol component, both types of fabrics exhibited higher values of thermal resistance, compressibility, drying capacity and water vapour permeability, while values for air permeability and bending rigidity were lower for untreated fabrics. The results of the optimisation of treated fabrics with machine-spun yarn as weft demonstrated the highest desirability value (0.73), as well as a lower percentage of wool fibres (55%), followed by treated fabrics with hand-spun yarn as weft, which demonstrated a desirability value of 0.66 and a percentage of wool fibres of 60% in the blend composition. Untreated fabrics (both machine-spun and hand-spun) exhibited a similar desirability value and at same blend composition (20% polyester, 70% wool and 10% polyvinyl alcohol). |
