摘要 本试验采用相关国家方法标准对321只羊驼毛绒样品开展了纤维细度及单纤维强力参数的检测,旨在分析羊驼毛纤维细度、单纤维强力及二者之间的相关性。结果表明,羊驼侧部毛纤维平均细度为24.30μm,细度主体范围为18.01~27.00μm,占样本总量的72%;平均纤维强力为8.31 c N,主体范围为5.01~11.00 c N,占样本总量的88%,说明羊驼毛整体细度较细,强力可满足纺织加工要求。羊驼毛细度和单纤维强力相关性分析发现,不同性别、年龄的羊驼颈部、肩部、股部、腹部、侧部、背部6个不同部位细度、单纤维强力都反映为背部最细,单纤维强力最小,腹部细度最粗,单纤维强力最大;另外,从羊驼毛不同细度区间对应单纤维强力分布也可看出,羊驼毛的单纤维强力值越大其细度值越大,反之越小;除此之外,不同性别、年龄的羊驼毛细度对应单纤维强力也呈正相关,成年羊驼毛细度粗于周岁羊驼,公羊驼毛细度粗于母羊驼,成年羊驼单纤维强力大于周岁羊驼,公羊驼单纤维强力大于母羊驼。综合以上结果,说明羊驼毛细度与单纤维强力呈正相关。 In this study,321 samples were tested to evaluate the correlation between fineness and single fiber strength of alpaca fiber. The results showed that fineness average of lateral part was 24.30 μm,subject range was from 18.01 to 27.00 μm,accounted for 72% of the total samples; The strength average was8.31 c N,subject range was from 5.01 to 11.00 c N,accounted for 88% of the total samples,it showed that the overall fineness of alpaca wool fiber was fine,the strength could satisfy the textile technology. The correlation results showed that the fineness of different parts( neck,shoulder,thigh,abdomen,lateral and back) in different groups( sex,age) all reflected that the wool fiber of the back was the finest,the strength was the minimal; And that of abdomen was the thickest,the strength was the maximum. On the other hand,we knew the greater the strength,the fineness was thicker; The smaller the strength,the fineness was finer from the distribution of different fineness range corresponded to the strength. In addition,there was also a positive correlation between them in differernt groups( sex,age),the fineness of adult alpaca was thicker than yearling alpaca,the male alpaca was thicker than female alpaca; The strength of adult alpaca was stronger than yearling alpaca,the male alpaca was stronger than female alpaca. The above results showed that the fineness of alpaca wool fiber was positively correlated with the single fiber strength.
