| dc.description.abstract | The present study was planned to see the possibility of blending of oak tasar silk waste and acrylic blended fibres to prepare yarns and woven fabrics. Blending and spinning of fibres were done on cotton spinning system. Five blend ratios (100:0, 60:40, 50:50, 40:60 and 0:100 Oak tasar waste: Acrylic) were prepared at NITRA, Ghaziabad on ring spinning. Their physical properties and imperfection were evaluated. Ten fabric samples were woven from developed yarns on handloom out of which four were blended fabrics with plain weave and four with twill weave. Two were union fabrics each with plain and twill weave in which 100 % acrylic yarn was used as warp and 100 % oak tasar silk yarn was used as weft. The physical (cover factor, cloth cover, fabric weight, fabric thickness, crease recovery angle, bending length, flexural rigidity, drape coefficient, abrasion resistance, pilling, tensile strength, elongation at break and dimension change) and comfort (thermal insulation value, clo, Q-max, air permeability, water vapour transport rate, water absorption, vertical wicking and horizontal wicking) properties were assessed and statistically analyzed using post hoc tukey test and paired t- test. The tenacity values of oak tasar silk and acrylic fibre were comparable. Acrylic fibres were finer as compared to oak tasar fibres. Elongation percent of acrylic fibre was higher as compared to oak tasar fibre. Yarn count of the developed yarns was ranged from medium to fine i.e. 22 Ne to 28 Ne. The physical properties, unevenness and imperfection of blended yarn were improved with the addition of acrylic fibres with oak tasar silk in the blend. Light weight plain weave and twill weave fabrics of oak tasar silk and acrylic blended yarns were developed among them the twill weave fabrics had higher cloth cover, fabric weight and thickness as compared to plain weave fabrics. Most of the physical properties of fabrics were improved with the addition of acrylic fibre in the blend for both plain and twill weaves. Comfort properties like Q-max, air permeability, water vapour permeability, thermal insulation and clo value were found to be increased with increasing acrylic content in the fabric. Most of the comfort properties of different blended and union fabrics were more or less close to each other for both plain and twill weaves. These fabrics may be used for light winter wear clothing and apparels as they were light in weight with clo value comparable to sweater. | en_US |
