Determining the Effect of Pigmentation on Some Physical and Mechanical Properties of Yak and Cashmere Down Fibers

Abstract

In this study, it was aimed to investigate the effect of pigmentation on the physical and mechanical properties of white and brown colored cashmere and yak down fibers in comparison with wool. According to experimental results, it was found that the pigmented fibers have higher diameter and length compared to their white equivalents. However, tenacity and elongation values were lower in pigmented fibers. On the other hand, it can be said that brown fibers had lower felting tendency compared to white fibers.
