Automatic pH Controlling System of Dyeing Machine

Abstract

AbstractDyeing is the most important and prime section of the textile manufacturing process. During dyeing, different types of faults occur which may cause huge loss of production cost, energy, and time. Batch-to-Batch shade variation, Patchy dyeing effect, Dye spots, Uneven dyeing, and Lighter shades are the most common dyeing fault in our textile dyeing manufacturing process. From a thorough investigation and a significant number of research works, we identified some common causes of those dyeing faults. Among them, improper chemical mixing in the mixing tank is one of them which changes the pH condition of the Dye-Bath and causes huge dyeing faults. In most cases, chemicals or dyes are applied to the dyeing machine manually and create these problems. During every production after a while pH of the Dye-Bath is checked manually. To avoid this manual pH checking system we propose a device that detects pH, monitor, and control it automatically. The device is designed with an Analog pH meter as pH sensor and 5v DC micro submersible motor pump, with an Arduino UNO R3 connected with a 4-channel Relay module, HC-05 Bluetooth module, and other parts. The sensor senses the pH of the Dye-Bath and the pumps will help to maintain the required pH in the vessel by pumping the proper amount of chemicals or dyes in the dye bath. Dyeing faults can be reduced significantly by controlling the pH of Dye bath and our developed system offers to do it automatically.KeywordsDye-BathDyeing faultpH monitoringpH controllingIoT-based automatic controlling system
