A whole-area temperature monitoring device for dyeing vats

Abstract

The invention provides a dye vat all-region temperature monitoring device which comprises a dye vat body. Temperature sensing constructional elements which are made of heat conduction metal are uniformly distributed on the dye vat body, a film cavity layer is arranged in the temperature sensing constructional elements, and liquid crystal printing ink is filled in a film cavity. Temperature measuring holes located in the same straight line are formed in two sides of the film cavity, optical fibers connected with the temperature sensing constructional elements in series are arranged in the temperature measuring holes and are respectively connected with a luminous source and a light sensing component which senses color mapping, and the light sensing component is connected with a conversion module which converts colors into temperatures. Through the liquid crystal printing ink arranged in the film cavity of the temperature sensing constructional elements, a color method is adopted in the temperature sensing constructional elements to transmit temperature information through the optical fibers, and the colors are converted into the temperatures in real time through the fact that the light sensing component arranged at one end of the optical fibers is matched with the conversion module.

Description

technical field [0001] The invention relates to the field of dyeing equipment, in particular to a monitoring device for monitoring the temperature of each area of ​​a dye vat. Background technique [0002] Textile materials are treated with a dye bath to chemically or physically combine dyes with fibers, or to generate insoluble colored substances on fibers. The dyestuff should have a certain resistance to washing, drying, rubbing and other properties on the fiber, which is called color fastness. Immerse the fiber in the dye aqueous solution at a certain temperature, and the dye will move from the water phase to the fiber. At this time, the amount of dye in the water will gradually decrease, and after a period of time, it will reach an equilibrium state. The dye that is reduced in the water is the dye that moves onto the fiber. When the fiber is taken out at any time, even if it is twisted, the dye remains in the fiber, and the dye cannot be completely separated from the f...

AI Technical Summary

Problems solved by technology

[0003] To dye clothes, you first need to place the fabric in the dyeing vat to make the fabric fully contact with the dye. At the same time, you need to heat the dyeing vat to a certain temperature to keep the molecular movement active. Dyeing has high requirements for temperature and temperature uniformity. Because the dyes in the dyeing vat tend to be concentrated on the upper part of the dyeing vat due to the heat, the dyeing effect of the clothes in the same dyeing vat is different, resulting in a low dyeing yield. Therefore, detecting the temperature of different positions in the dyeing vat becomes a corresponding Important Basis for Measures
