中文摘要：针对机织物接缝强力在测量过程中影响因素较多,易产生较大不确定度的问题,分析了按照GB/T 13772.1—2008《纺织品机织物接缝处纱线抗滑移的测定第1部分:定滑移量法》测定织物接缝强力的不确定度产生因素,并对产生不确定度的分量进行评定与合成,得出合成不确定度与扩展不确定度。结果表明:织物取样要从中间批次选择幅宽、均匀度、密度一致的试样;裁样前先沿经纬向纱线各拆下1根标记纱线,利用标记纱线量取试样;根据不同的纤维成分,测试之前织物应充分调湿;织物测试前都应首先利用一块空白试样调节针距,保证测试样的针距为(50±2)针/100 mm;采用250 N感应器,拉力机速度为(50±5)mm/min,力值误差不应大于±1%,距离误差不应大于±1 mm。所测试样的扩展不确定度为4 N。

外文摘要：Greater uncertainty may be produced in the measurement process of seam strength because of lots of affected factors. The main sources of uncertainty in GB/T 13772.1-2008 “determination of the slippage resistance of yarns at a seam in woven fabrics, part 1： fixed seam opening method” was discussed. And each component of uncertainty was estimated and composed. The combined and expended uncertainties were given. Analysis showed that fabric samples should be selected from the middle of each batch and the width, uniformity and density should be the same. A yarn along longitude or latitude should be marked before preparing samples, which is used to cut samples. Fabric should be conditioned completely according to different of fiber components. The stitches should be （50 ± 2）/100 mm, which is guaranteed by a blank sample. The machine electrical sensor is 250 N, rate of extension is （50 ±5） mm/min, the error of strength should not exceed ± 1% , the error of distance shall not exceed ± 1 mm. The expanded uncertainty of this sample is 4 N.
