摘　　要：目的调查医用织物洗涤后着色的原因,寻找避免织物着色的方法。方法接触氯己定后再与含氯消毒剂接触的医用织物为试验组,接触乙醇、洗衣粉再接触含氯消毒剂为对照组;通过不同的接触与洗涤方法,观察各组着色及褪色情况。结果试验组接触250～500mg/L次氯酸钠后1min即出现着色,洗涤后不能褪色;改进洗涤方法后与对照组均无着色现象。结论氯己定与次氯酸钠接触可发生化学反应,生成对氯苯胺沉淀,使医用织物着色。OBJECTIVE To survey the coloration effect of medical fabrics after washing,to put forward the way to avoid coloration. METHODS Medical fabrics which soaked chlorhexidine and contacted chloro-disinfectants were set as experimental groups,which soaked alcohol and washing powder and then contacted chloro-disinfectants were set as control groups.Then the coloration and situation of color fading after different contacted and washing ways were observed. RESULTS Experimental groups which contacted the solution comprised of 250-500 mg/L chloro-disinfectants were colorated after 1 minute and cannot fading after washing.The coloration did not occur after improved washing ways,same as the control groups. CONCLUSION Chemical reaction will occur between chlorhexidine and sodium hypochlorite and produces p-chloroaniline which can colorate medical fabrics.
