Dye liquor concentration in-situ on-line monitoring method

Abstract

The invention provides a dye liquor concentration in-situ on-line monitoring method. The dye liquor concentration in-situ on-line monitoring method comprises the following steps that 1, an optical fiber sensing probe is put into dye liquor needing to be monitored; 2, light beams emitted by a light source are transmitted and are partly adsorbed by the dye liquor; the penetrable light beams reach a reflection mirror and are reflected into the dye liquor by the reflection mirror; the reflected light beams are adsorbed by the dye liquor again; and the penetrable light beams return to an emission mirror, 3, the light beams returning to the emission mirror are transmitted to an optical fiber spectrometer by optical fibers and through the optical fiber spectrometer, an absorbance value and a transmittance value at a specific wavelength are obtained; and 4, an analysis result obtained by the optical fiber spectrometer is transmitted to an analysis processing device; and the analysis result obtained by the optical fiber spectrometer is processed by the analysis processing device so that dye liquor concentration variation with time is known. The dye liquor concentration in-situ on-line monitoring method solves the problem that the existing dye liquor concentration on-line monitoring method has hysteresis quality and can produce a large error. The dye liquor concentration in-situ on-line monitoring method provided by the invention can realize real-time dynamic in-situ on-line monitoring of a dye liquor concentration.

Description

technical field [0001] The invention relates to the field of liquid concentration measurement, in particular to a method for online measurement of dye liquor concentration. Background technique [0002] Textile products can be seen everywhere in our lives. The colors and patterns of these textiles are generally processed by printing and dyeing. In the textile printing and dyeing process, the concentration of dyes in the dyeing liquor changes at any time. In order to ensure that the product color of the textile during the dyeing process is consistent with the standard sample, it is necessary to monitor the composition and concentration of the dye in the dye solution, the dyeing temperature, and the dyeing rate at any time. The dyeing methods of textiles can be divided into dip dyeing and pad dyeing. For a long time, in the printing and dyeing process, the dyeing technicians mainly rely on their long-term accumulated experience to adjust the dye components and concentrations...
