The Effect of Wool Fiber Variables on Tactile Characteristics of Homogeneous Woven Fabrics

Abstract

This work examined the extent to which wool fiber variables (fiber diameter, length and bulk) influence the tactile characteristics of otherwise homogeneous fabrics, i.e., fabrics constructed from standardized fiber content, yarn structure, dye, and finishing treatment. Subjects were 24 female students enrolled in advanced Clothing and Textiles courses at the University of Otago and 20 male Textile Scientists. Results showed that structurally homogeneous fabrics (but with differing wool fiber variables) could be distinguished as having different tactile characteristics. Significant differences in the ranking of roughness (F (5,42) = 11.29, p < .001) and prickliness (F (5,42) = 12.84, p < .001) occurred among these fabrics. Smooth and less prickly perceptions were associated with fiber diameter of less than 23 microns and fiber bulk greater than 31 cm³/g; rougher and more prickly perceptions occurred when fiber diameter was greater than 34 microns and fiber bulk less than 21 cm³/g. No significant difference was found among fabrics on the basis of warmth to the touch (F (5,35) = 1.52, ns).
