摘　　要：迭代涤纶(ITER-C)/腈纶一浴染色容易出现色差。测定单组分纤维上染曲线,讨论两种纤维同浴染色的可行性。测试染色温度、pH对两种纤维一浴染色性能的影响。测定两种纤维一浴染色的上染曲线和提升力曲线,进一步探讨了阳离子染料对两种纤维一浴染色的染色效果。结果表明:ITER-C在50℃、腈纶在70℃时,上染率快速上升,100℃后逐渐稳定;ITER-C/腈纶一浴染色时,优化染色温度为105℃、优化染色pH为4.5,阳离子染料在ITER-C上的上染率高于腈纶,染料用量低于4%(omf)时,染料用量越高,纤维同色性越好。One-bath dyeing iterative polyester ITER-C/acrylic is prone to color difference.The feasibility of one-bath dyeing of two types of fibers is discussed by measuring the dyeing curve of both single-component fibers.The effects of dyeing temperature and pH on the one-bath dyeing property of two types of fibers are tested.By measuring the dyeing curve and build-up curve of the two types of fibers in one-bath dyeing,the dyeing effect of cationic dyes on the two types of fibers in one-bath dyeing is further explored.The results show that the dye uptake increases rapidly at 50℃for ITER-C and 70℃for acrylic fiber and stabilizes gradually after 100℃.When dyeing ITER-C/acrylic fibers in one bath,the op-timal dyeing temperature is 105℃and the optimum dyeing pH is 4.5.The dye uptake of cationic dyes on ITER-C is high-er than that of acrylic fibers.When the dye dosage is below 4%(omf),the higher the dye dosage,the better the fiber union dyeing property.
