Determining the Permeability and Handle Properties of Wool, Yak and Cashmere Hand-knitted Fabrics
(Taylor & Francis Inc, 2023) Unal, Pelin Gurkan; Atav, Riza; Ergunay, Ugur
Luxury fibers are used for their tactile properties, comfortable feeling for the users, and sometimes for status in society. These fibers are all protein-based and have always been compared to the properties of wool. Cashmere is known for its incredibly soft and warm yet lightweight and breathable qualities, making it a must-have fabric for any fall and winter closet. Besides labored and time-wasting cashmere production makes the fiber very expensive. Yak fiber is an alternative to expensive cashmere with similar properties, which costs only a quarter of cashmere. In this study, air and water vapor permeability properties, which are important for consumer comfort were investigated in addition to handle properties of the fabrics compared with the properties of the fabrics made of wool fibers. It was found that yarns made of wool fibers were easy to spin in fine yarn counts whereas yarns made of yak fibers were the coarsest. Hand-knitted fabrics made of cashmere fibers had the softest feeling even if the fabrics were produced with similar technical specifications. The permeability results of the fabrics were different, especially the porosity of the fabrics had a higher impact on the permeability of the fabrics.
