Impact of shearing season on quality characteristics of camel hair fibers
To investigate the influence of seasonal factors on the quality traits of camel hair fibers,experiments were conducted at two significant stages:the spring shearing period and the autumn regrowth period.Two sampling events were carried out on 204 camels,all from the same ranch and consisting of brown female camels of the same age,under identical feeding conditions,resulted in a total of 408 bags of camel hair samples collected in spring and autumn.The fiber length,diameter,and tensile properties were tested,and the frequency distribution,surface microscopic morphology,and quality traits of camel hair samples in spring and autumn were analyzed and compared.The results reveal that the average fiber length of camel hair in spring was significantly higher than that in autumn(P<0.001).Similarly,the average fiber diameter in spring was significantly higher than that in autumn(P<0.001).The diameter variation coefficient in spring was significantly higher than that in autumn(P<0.05).Regarding tensile properties,the breaking strength in spring was significantly lower than that in autumn(P<0.001),and the breaking force in spring was also significantly lower than that in autumn(P<0.001).Moreover,the breaking elongation in spring was significantly higher than that in autumn(P<0.001),and the breaking elongation rate in spring was significantly higher than that in autumn(P<0.001).Additionally,the initial modulus in spring was significantly lower than that in autumn(P<0.001).
