Study on Curly Elastic Properties of Variational Cashmere about Different Breeds

Due to improved seed selection, changes in the natural environment and rearing methods and changes in the subjective and objective factors. Recent years, the curly elastic properties of cashmere fibers also occurs a certain degree of variation. Curly elastic properties affect the spinnability of the spinning, yarn pilling performance and fabric pilling performance, therefore the curly elastic properties of the variational cashmere fiber is very important to study. The curly elastic properties of the sheep species variational cashmere fiber, non-variant cashmere fiber, Australian superfine wool fibers were tested in this article. By the analysis of the data, the article obtained the variation of four variational cashmere fiber (coarse fiber, the dimorphic fiber, two fine fiber, cashmere fiber). The tests showed, for ewes, the coarse fiber’s curl, crimp recovery rate is creased significantly, the number of dimorphic fiber curl significantly lower. For rams, the two fine fiber curl, crimp modulus of elasticity and curl the response rate has significantly improved. With rams, ewes, the dimorphic fiber curl were significantly higher than non-variant cashmere.
