山羊绒手排长度测定结果不确定度评估

Uncertainty evaluation of the results of determination of cashmere hand row length

在山羊绒产业链里面,分梳其长度是很重要的一部分。山羊绒的长度是否达标,直接决定它的成品或者半成品的品质,最后的品质标准就是其长度的精准度。GB18267—2013是分梳山羊绒长度的标准。常规山羊绒采用手排长度的方法,这种方法也是测量其标准度的一种方便直接的方式,就是把分梳的山羊绒在绒板上列出标准的规则后,通过科学的计算和测量,算出最后的长度。在这个过程中,责任人员的熟练程度就决定了山羊绒纤维手排的长度,由于没有准确的器械帮助实验人员,可能会影响最后的标准度。

In the entire goat production chain, the length of the combing is an important part. Whether the length of cashmere is up to standard directly affects the quality of its finished or semi-finished products, so the final quality standard is the accuracy of its length. Up to now, GB 18267-2013 is the standard quality method for the length of carded cashmere. The method of the length of the hand in the “Cotton” standard is now the most convenient and straightforward way to measure its standard. The way to do this is to put the combed cashmere on the board with the standard rules and calculate the final length by scientific calculations and measurements. In this process, the proficiency of the responsible person determines the length of the cashmere fiber hand row, and there is no accurate instrument to help the tester, so it will affect its final standard.
