System for inspecting and controlling dyeing liquid component of dyeing machine on-line

Abstract

A detection and control system of dyeing liquid composition used on dyeing machine comprises addition unit of dyeing liquid composition, on - line detection unit of reducing agent and pH value for dyeing liquid, sampling pump and computer. It is featured as using potentiometric titration to detect reducing agent concentration in dyeing liquid and pH value of dyeing liquid on - line with set time, comparing obtained value with set value and controlling addition unit to add dyeing liquid according to compared result to keep dyeing liquid composition to be the same as set value for ensuring quality of dyeing.

Description

technical field

[0001] The invention relates to a system for detecting and controlling the dye liquor components of a dyeing machine in textile printing and dyeing, and belongs to the field of dyeing textiles with vat dyes. Background technique

[0002] The detection and control of traditional vat dyes in textile printing and dyeing basically adopt manual detection and manual control. In this control method, due to the long time interval of manual detection, the addition of dyes and auxiliaries varies from person to person, and the responsibility of the dyeing control personnel is different, human factors have a greater impact on the dyeing quality, and it is easy to cause The instability of various components of the dye solution in the dyeing tank, especially the color difference before and after dyeing. Therefore, ensuring the stability of various elements related to dyeing and reducing the influence of human factors has become the key to controlling color difference in d...
