新疆阿克苏地区羊驼毛品质分析

试验旨在研究阿克苏地区引进羊驼的毛绒品质现状。采用相关方法标准对新疆阿克苏地区塔格拉克牧场引进的158只羊驼进行平均纤维直径、毛丛自然长度、净毛率、单纤维强力、原毛油脂含量及卷曲指标的测定，统计分析性别、年龄、被毛颜色对测定指标的影响。结果表明，阿克苏地区引进羊驼毛平均纤维直径23.36 μm，毛丛自然长度106.14 mm，净毛率80.90%，断裂强力8.04 cN，断裂伸长百分比40.11%，原毛油脂含量2.08%，卷曲6.70个/2.5 cm。不同性别的羊驼毛丛自然长度、净毛率、原毛油脂含量差异显著（P<0.05）；不同年龄的羊驼纤维直径、毛丛自然长度、断裂强力及原毛油脂含量差异显著（P<0.05）；不同被毛颜色的羊驼毛丛自然长度、纤维直径、原毛油脂含量及卷曲差异显著（P<0.05）。综上可知，阿克苏地区引进的羊驼在纤维直径、毛丛自然长度方面较优良，且性别、年龄、被毛颜色对羊驼毛纤维遗传性状存在显著影响。

Analysis of Alpaca Wool Quality in Akesu Area of Xinjiang

The aim of this study was to know the current quality situation of wool from introduced alpaca in Aksu area of Xinjiang.158 introduced alpaca were selected from Tagelake farm in Aksu area,and fiber samples were collected for the measurement of fiber diameter,fiber length,net wool rate,single fiber strength,raw wool grease and fiber crimpy,and the influences of gender,age and coat color on these fiber indexes were analyzed.The results indicated that the average fiber diameter was 23.36 μm,fiber length 106.14 mm,net wool rate 80.90%,breaking strength 8.04 cN,breaking elongation 40.11%,raw wool grease 2.08% and fiber crimpy 6.70 number/2.5 cm.There were significant differences in fiber length,net wool rate and raw wool grease between genders (P<0.05),significant differences in fiber diameter,length,breaking strength and raw wool grease among different ages (P<0.05),significant differences in fiber diameter,fiber length,fiber crimpy and raw wool grease among different coat colors (P<0.05).In conclusion,the mean fiber diameter and length of alpaca wool in Aksu area were excellent,and gender,age and coat color of alpaca had significant influence on the genetic characteristics of wool fiber.
