一种快速测定分散染料染色强度的方法

A Rapid Method for Determination of Disperse Dyes Dyeing Strength

摘要: 针对贸易类企业、第三方检测机构等在多厂家、未知强度分散染料样品染色强度检测中遇到的需多次复染的问题，开发了一种快速检测分散染料染色强度的方法——透射检测法与染色检测法相结合的方法。本文通过对大量分散染料样本透射检测法的分光强度和染色检测法的染色强度结果对比，发现对于大多数的分散染料，分光强度与染料的染色强度十分接近，同时可结合染色检测法，可一次性得到准确的染色强度数值和色光。大大减少了检测时间，降低了布样、染色机器及化学试剂等的消耗，提高了检测效率，降低了检测成本。

Abstract: Aiming at the repeated dyeing demand encountered in the trade oriented enterprises and third party testing organizations, and problems existing in many manufacturers during the unknown strength detection process of various disperse dyes, a rapid method for strength determination of disperse dyes is developed—the combination of transmission detection method and dyeing detection method. The spectro strength of the dye by the transmission detection method was contrasted with its dyeing strength by dyeing detection method. After a large numbers of detailed comparisons of disperse dyes samples, the results showed that most of them are very close. So we can combine the two methods to get accurate dyeing strength and shade, with the advantages of short time, less consumption of cloth and dyeing machines and other chemical reagents, low cost, and greatly improved detection efficiency.
