摘　　要：棉织物在氧漂工序中容易出现破洞现象,为了查清破洞产生的原因,本文将不同破洞的棉织物放入20 mL硫代硫酸银络合物测试溶液中煮沸2 min,用去离子水冲洗后观察破洞周围的颜色变化。结果表明,由机械等外力造成的破洞,破洞口与布面颜色一致;因局部过度氧化引起的破洞,破洞口颜色比布面颜色深。通过X射线衍射仪、扫描电镜和X射线光电子能谱仪对其进行表征,得出棉织物经测试溶液检测后,表面有银析出,颜色深的洞口含银量比其他部位多,表明这类棉织物破洞是因为局部过度氧化造成的。In recent years,cotton fabrics,especially summer clothing,have been increasingly favored by young people in domestic market for their mercerization,moisture absorption,breathability and soft touch,and the market potential demanding for cotton cloth has been huge.Under the requirement of energy saving and emission reduction for high energy-consumption printing and dyeing enterprises by the Chinese government,most dyeing plants have adopted the more efficient short process of one-bath one-step cold pad-batch for cotton cloth bleaching.The hydrogen peroxide added in this process is over three times more than that of the traditional process.After oxygen bleaching mercerization of the cotton cloth,local excessive oxidation occurs and oxygen bleaching holes are more likely to occur.In the production process of cotton cloth,the selection process of different cotton cloth specifications is different,resulting in complex reasons for holes.Therefore,it is necessary to find out the causes of holes in the production process and formulate corresponding preventive measures and technological processes.In this experiment,aldehyde cellulose produced by bleaching cotton cloth with hydrogen peroxide was oxidized by a self-made weak oxidation reagent,so that metal silver atoms could be directly precipitated on the cloth surface.According to the number of silver atoms precipitated from the cloth surface and the hole opening,the color depth was formed,the intensity of hydrogen peroxide decomposition was judged,and whether the hole on cotton cloth was caused by excessive oxidation was proved from the side.Then,1 mL of 8%silver nitrate solution,and 2 mL of mixed solution of 20%sodium bicarbonate and 20%caustic soda were added into 17 mL of deionized water.Then,the mixed solution was shaken up quickly.Subsequently,5g of cloth with holes was boiled in the solution for 2 min under 100℃,and then it was washed with deionized water.The color difference around the hole of that fabric was observed.The cotton cloth with holes were characterize
