Abstract:

To enhance the repeatability and reproducibility of the method for testing the hair-loss quantity according to the standard Raised Silk Scarf and Shawl (FZ/T 44007-2019), and to avoid test failure, the method was studied. The sample area was measured using several different methods. A suction filtration experiment was performed using sand core funnels with four different pore diameters. A hair-loss experiment was then performed using sand core funnels with different pore diameters by different measurement means. The research results showed that different measurement locations and measurement methods may lead to great differences in the sample area results. The adoption of sand core funnels with different pore diameters had different suction filtration efficiency, and also affected the experiment results. Finally, recommendations for test method improvement were proposed. By specifying the effective area measurement method of the sample and the pore diameter of the sand core funnel, it is hoped to improve the repeatability and reproducibility of the experiment.

Key words: raised silk scarf and shawl, hair-loss quantity, effective area, sand core funnel

摘要：

为了提高标准FZ/T 44007—2019《蚕丝拉绒围巾、披肩》中脱绒量试验方法的重复性和重现性,防止出现试验失败,对该方法进行了研究。采用几种不同方法测量试样面积,并用4种不同孔径规格的砂芯漏斗进行抽滤实验,以及综合采用不同测量方法和不同孔径规格的砂芯漏斗进行脱绒量实验。研究显示不同的测量部位和测量方法易使试样面积结果产生较大差异,不同孔径规格的砂芯漏斗抽滤效率不同,并且对实验结果也有影响。提出了完善该试验方法的建议,通过对试样有效面积测量方法和砂芯漏斗孔径规格作出细化规定,提升实验的重复性和重现性。
