摘要：
[Objective]Aimed to study the nature,characteristics and ultrastructure of fibers of Ovis aries and several kinds of special animals.[Method]Wool,cashmere,alpaca,Bactrian camel hairs,rabbit hair,mohair and yak hair were used as the experimental materials,and scanning electron microscopy was used to observe their scale structure.[Result]The rake angle of wool was large with an average of 33.2°,the scale density was 16.2-34.9 scales/mm,the average height of scale was 12.95 μm,and the average thickness was 0.63 μm;the rake angle of cashmere was smaller than wool with an average of 20.6°,the scale density was of 10.3-15.6 scales/mm,the scale distance was large,the average height of scale was 16.09 μm,and the average thickness was 0.46 μm;the average rake angle of alpaca was 34.6°,with the average scale height of 5.85 μm,and average thickness of 0.33 μm;the average rake angle of camel hair was 33.5°,with the average scale height of 11.30 μm and average thickness of 0.37 μm;the average rake angle of rabbit hair was 31.2°,with average scale height of 7.03 μm and average thickness of 0.36 μm;the rake angle value of mohair was between wool and cashmere,and the average of which was 23.7°,the scale density value was also between the wool and cashmere,with the average scale height of 15.82 μm and average thickness of 0.61 μm;the average rake angle yak hair was 33.2°,with the average height of 9.08 μm and average thickness of 0.46 μm.[Conclusion]The results of this study could provide a basis for the identification of different fiber types.
