Abstract: In this study,111 Jinzhong sheep fiber samples were tested to evaluate the quality and utility value in aspects of average fiber diameter,length,strength,color,lightness,percent yield of clean wool,grease and fiber types. The results showed that the net gross rate of Jinzhong sheep wool average about 80.30%.The fiber type test results found the fiber of Jinzhong sheep contained down hair,down hair was 46.91%. The average fiber diameter of down hair from shoulder from 19.01 to 23.00 μm,about 18.02% fiber under 19.00 μm,it showed the fineness quality of Jinzhong sheep down hair and the fiber length of down hair scattered from 20 to 60 mm,the numbers occupied 80.19% of the total samples,and the length distribution was more spread out,it showed high individual difference. This test found that Jinzhong sheep could produce down hair,the textile value of some down fiber was remarkably superior to fine wool and cashmere.
