Evaluating the Physical and Fabric Hand Characteristics of Lyocell Fabrics Made with Different Wood Pulps

Abstract

Four different kinds of wood pulp are used to make lyocell fabric and its intermediate products, and each is evaluated in terms of its physical characteristics and fabric hand values measured with the Kawabata Evaluation System for Fabrics. The rank orders of fiber, yarn, and fabric characteristics as a whole suggest that H4 pulp is ranked highest for its physical characteristics, thus producing textile intermediates with higher strength and dimensional stability than the other pulp types. Comparing such physical results with the KES-FB rank orders, it appears that high strength and stability along with high elongation and crimp factors are less significant for characterizing fabrics with higher hand values. For lyocell fabrics made from yarns with higher CV%, the results are more favorable for increasing the hand values of numeri, fukurami, sofutosa, and shari characteristics, and such fabric hand as a total is an important requirement for women’s suit fabrics.
