Analysis on the Yarn and Fabric Characteristics of Chiengora Fibers from Hairs of Lhasa Apso Breed and Its Blends in Comparison with Wool and Its Blends. Part II – Fabric Characteristics

Abstract

ABSTRACT The chiengora yarns and woolen yarns along with polyester and acrylic are knitted into fabrics with 2 × 2 rib structures in 16 blend proportions. The properties of the chiengora fabrics and its blends are ascertained and compared with the properties of developed knitted wool fabrics and its blends. It is observed that the bursting strength of fabrics decreases with increase in chiengora content similar to woolen fabrics. The air permeability, wickability, and water vapor permeability are found to be lesser for 100% chiengora fabrics similar to the woolen fabrics. The chiengora fabrics possess better thermal insulation property. The 100% lhasa apso fabric has a thermal insulation value (TIV) of 0.606 clo, which is 38% more than the 100% wool fabric, which has 0.373 clo, thereby confirming that these fabrics can be used for thermal wears like sweaters. The presence of scales and thermal properties indicates better thermal insulation properties for these chiengora fiber fabrics. The 75/25 lhasa apso polyester fabrics can be considered as the better blend proportion than other produced fabrics due to their better yarn properties, comfort properties, and higher TIV than wool. The end use for all the produced chiengora blended fabrics is given based on the TIV.
