摘　　要：为了改善酸性染料对锦氨织物同浴染色时氨纶得色较浅且牢度较差的问题,采用加入氨纶上色剂的方式以提高锦氨同色性及色牢度。探究了不同氨纶上色剂对提高氨纶K/S值的差异及其最佳用量,并考察了氨纶上色剂应用于不同染料染色时对锦氨同色性及其色牢度的影响。结果表明:氨纶上色剂对氨纶K/S值有良好的提升效果,且适用于多种单色和拼混染料,对不同的染料提升效果不一。在上色剂质量分数为1%~2%时,其可有效改善锦氨织物染色同色性,且耐皂洗色牢度也有明显的提升。本研究结果可为锦氨织物的实际生产提供数据参考。In order to improve the light color and poor color fastness of polyamide/spandex fabric in one bath dyeing with acid dyes, the method of adding spandex colorant in dyeing was adopted to improve the homochromaticity and color fastness of polyamide/spandex fabric. The effects of different spandex colorants on improving the K/S value of spandex and their optimum dosage were explored. The effects of spandex colorant applied to different dyes on the homochromaticity and colour fastness of polyamide/spandex fabric were also investigated. The results show that spandex colorant has a good effect on improving the K/S value of spandex, and it is suitable for a variety of monocolour and blended dyes. It has different effects on different dyes. When the dosage is between 1% and 2%, it can effectively improve the homochromaticity of polyamide/spandex fabric. Meanwhile, the colour fastness to soap washing is also significantly improved. This study can provide data reference for the actual production of polyamide/spandex fabric.
