A method of digitized analysis of compatibility of a dye composition by adoption of a spectrometer

Abstract

A method of digitized analysis of compatibility of a dye composition by adoption of a spectrometer is disclosed. The method includes: subjecting cloth samples in different heating stages of the dye composition to color measuring and matching by a datacolor spectrometer, acquiring different formula concentrations of the dye composition by color measuring and matching, sorting out corresponding dye uptakes in different dyeing heating stages of each dye in the dye composition, and showing all the dye uptakes of each dye in one chart, then the compatibility of the dye composition can be clearly determined. At present, manners of evaluating dye uptakes and compatibility by spectral analysis of dye solutions do not consider influence factors of dye hydrolysis in dyeing processes, while the method provided by the invention relates to evaluation of the dye uptakes and the compatibility for the actual colors of fabrics after dyeing, so that results of the method are more reasonable and impersonal, the method can show actual dyeing performance of fabrics at present dyeing conditions well, and the method facilitates optimization of dyeing processes and improvement of formulas.

Description

technical field [0001] The invention relates to the field of textile dye analysis methods, in particular to a method for digitally analyzing the compatibility of dye combinations by using a spectrometer. Background technique [0002] The traditional way to evaluate the compatibility of dye combinations is to use a laboratory proofer to take samples step by step, and to visually evaluate the color change of the fabric after step-by-step sampling. It is impossible to digitally evaluate the dyeing synchronization and determine the dyeing heating process. This method of visual evaluation can only be judged qualitatively, and the judgment is easy to vary from person to person, resulting in large errors. However, the currently widely used method of evaluating the dyeing uptake rate and compatibility through spectral analysis of the dyeing solution does not consider the factors affecting the hydrolysis of the dye during the dyeing process.

Problems solved by technology

[0002] The traditional way to evaluate the compatibility of dye combinations is to use a laboratory proofing machine to take samples step by step, and to evaluate the color change of the fabric after step-by-step sampling with the naked eye. It is impossible to digitally evaluate the dyeing synchronization and determine the dyeing heating process.

This method of visual evaluation can only be judged qualitatively, and the judgment is easy to vary from person to person, resulting in large errors

However, the currently widely used method of evaluating the dyeing uptake rate and compatibility through spectral analysis of the dyeing solution does not consider the factors affecting the hydrolysis of the dye during the dyeing process.

The other kind of spectroscopic instrument is used to test the dye uptake rate or dye strength, which only calculates the dye uptake performance of the color based on the K / S value formula. It can only analyze the dye uptake performance of the overall dye combination, and cannot use the K / S value. The formula calculates the specific dye uptake rate or dye strength of each dye in the dye combination, and the compatibility of the dye combination cannot be digitally analyzed
