取绒方式对山羊绒纤维品质的影响

Influence of cashmere collecting methods on fiber quality

针对不同年龄的山羊绒纤维特点及采绒方式对羊绒纤维品质的影响,分析了不同采绒方式(抓绒和剪绒)对山羊绒纤维平均长度和平均细度的影响。试验结果表明:随着生长旺盛期绒山羊年龄的增加,3年内山羊绒纤维平均长度增加了2.43~3.52 mm,平均细度增加了1.50~1.53μm。瓜子绒比套子绒平均长度偏长2.77 mm,平均细度偏细0.27μm。通过光学显微镜和扫描电子显微镜分析皮退绒和自然脱落山羊绒纤维根部状态,可鉴别出二者的区别,对鉴别自然脱落的山羊绒和皮退绒具有参考价值。

In view of the characteristics of cashmere fibers of different ages and the influence of cashmere picking methods on cashmere fiber quality,the influence of different cashmere collecting methods(combing and shearing)on the average length and fineness of cashmere fibers was analyzed in this paper.The results show that the average length of cashmere fiber increased by 2.43-3.52 mm and the average fineness increased by 1.50-1.53μm with the increase of cashmere goat′s age in the vigorous growth period.The average fiber length of combed cashmere is 2.77 mm longer than that of sheared cashmere and the combed cashmere is 0.27μm thinner than sheared cashmere.The fiber root state of normal cashmere and skin cashmere is analyzed by optical microscope and scanning electron microscope,which has high reference value for identifying normal cashmere and skin cashmere.
