【摘要】 活性染料固定率测定一般采用分光洗涤法,为了简化其测定操作,文中以活性染料染色的理论为基础,应用现代计算机测色配色技术,探讨了K/S值涂布法测定活性染料固色率的可行性。测定了不同染料涂布时,染料浓度与织物K/S值的关系曲线;测试并比较了K/S值涂布法固色率与分光洗涤法固色率。结果表明,涂布法制备染样的K/S值随着染料浓度的提高而增加,涂布法可以获得固色率100%试样的K/S值;K/S值涂布法测定活性染料固色率具有一定的可行性,且操作简便。更多还原

【Abstract】 In order to simplify the operation of testing fixation rate of reactive dyes by spectrometry washing method, feasibility of coating method in testing fixation rate of reactive dyes by K/S value was discussed,which was based on dyeing theory of reactive dyes and applied the modern computer color-measuring and color-matching technology. The relation curve of dyes concentration and K/S value of fabric was tested when using coating method by different dyes. The fixation rates of coating method with K/S value and spectrometry washing method were tested and compared. The results show that K/S value increases with the improving of dyes concentration, and K/S value when fixation rate is 100% can be obtained by coating method; coating method has certain feasibility in testing fixation rate of reactive dyes by K/S value, and the operation is simple.更多还原
