Subjective and objective/machine evaluation of wool luster in Magra sheep vis-a-vis wool grading and animal selection

ABSTRACT

Wool of Magra sheep in India is well-known for its fiber quality and luster. In the present study, subjective and objective luster grading wool clips and its association with fiber diameter was done. It was found that for higher luster grades, their fiber attributes are closer to lower limits of ideal carpet wool, viz. fiber diameter and proportion of medullated fibers to 30 µm with medullation 30%. Canary colored wool’s whiteness index (L*) may be considered as one of the physical properties for identification of wool luster. Subjective grades indicated that visual grading of wool samples was very close to the quality appraisal of attributes.

摘要

印度马格拉羊毛是纤维品质和光泽众所周知。本研究采用主观和客观的光泽分级羊毛夹及其与纤维直径的关系。结果发现，对于高光泽等级，其纤维属性接近理想地毯羊毛的下限。纤维直径和有髓纤维30µM 30%的比例形成作用。白羊毛白度指数（L*）可作为羊毛光泽鉴别的物理指标之一。主观评分表明，羊毛样品的视觉分级与品质评价非常接近。
