Abstract
A low temperature dyeing process of cashmere has the advantages of saving energy and causing less damage to fibers. In this paper, the tensile properties of dyed cashmere by low-temperature dyeing and conventional dyeing were tested using a single fiber tensile tester. The surface morphologies of raw cashmere and dyed cashmere were observed by scanning electron microscopy (SEM). The SEM pictures show that the damage of the surface scale of cashmere by low the temperature dyeing process was much less than by the conventional dyeing process, and the tensile strength of deyed cashmere fiber by low-temperature dyeing was found to be high. Light-color and medium-color cashmere fibers dyed with Pula dye by low-temperature dyeing have good color fastness.
