摘　　要：使用不同比例单色棉纤维和本色棉纤维经混纺、织造后得到色纺针织面料样品,用测色软件对样品上选定的区域进行成像,然后微分成大量单元进行测色。经分析发现,色纺针织物的色彩均匀度,可以用各测色单元相对于标准色色差ΔEi的CV值来表征,该CV值和人工目测得到的色彩均匀度等级存在高度的相关性。当CV值大于2.0%时,样品的色彩均匀度较差,存在显著的色彩分布不均匀;当CV值小于1.0%时,样品的色彩均匀度较好,外观上仅有轻微差异或无法觉察。In this paper,of single-colour cotton fibre with different ratio is blended with grey cotton fibre,then spun and knitted to gain fibre-dyed knitted fabric samples.The colour testing software was used to image the chosen zone on the sample.Then,the zone is differentiated into a large number of units for colour testing.The analysis shows that the colour uniformity of these fabrics can be characterized by CVvalue of colour differenceΔEiof each colour testing unit relative to standard colour.The CVvalue is highly related to colour uniformity grade gained by manual visual inspection.Furthermore,when CVvalue is higher than 2.0%,colour uniformity of samples is bad,and significant colour distribution unevenness exists.When CVvalue is less than 1.0%,colour uniformity of samples is good,and there is only slight difference or invisible difference on the appearance.
