Textile fabric PH value detection device

Abstract

The invention relates to the technical field of textile, and discloses a textile fabric PH value detection device, which comprises a rotating shaft and a movable groove. A sealing box is fixedly mounted in the movable groove, the sealing box is filled with magnetorheological fluid, a limiting rod is inserted in the sealing box, the outer side of the limiting rod is movably connected with a connecting spring, the outer side of the connecting spring is movably connected with an extrusion rod, and the outer side of the extrusion rod is movably connected with a movable block. According to the textile fabric PH value detection device, during detection, a rotating shaft rotates, a movable block is extruded to move towards the inner side, and an extrusion rod moves towards the inner side, so that a dielectric plate moves towards the inner side of the rotating shaft, a piezoresistor is in a closed circuit, an electromagnet is electrified, the electromagnet and a magnetic block repel each other, and a sealing block shrinks; the phenolphthalein reagent in the loading box is in contact with the cloth, the acid-base property of the cloth is detected, the operation is simple, time and labor are saved, and the detection result is obvious.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a detection device for the pH value of textile fabrics. Background technique [0002] The original meaning of textile is taken from the general term of spinning and weaving, but with the continuous development and improvement of the textile knowledge system and subject system, especially after the emergence of non-woven textile materials and three-dimensional composite weaving technologies, it is not only the traditional hand spinning And weaving, including non-woven technology, many personal clothing in our lives are made of textile fabrics, the pH value of textiles refers to the residual acid and alkali content in the fabric, which is a harmful substance that affects human safety and health One of the limited indicators. [0003] The skin of the human body is generally weakly acidic. If the PH value of textiles exceeds the standard, it will destroy the weakly acidic environme...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a detection device for the pH value of textile fabrics, which is simple to operate, improves the safety of the fabric, saves time and effort, and is easy to observe the detection results. It is simple to operate and improves the safety of the fabric. It saves time and effort, and the test results are easy to observe. It solves the problem that the pH value of textiles exceeds the standard, which will destroy the weak acidic environment on the surface of the human skin, cause itching, and make the skin vulnerable to other germs, and even cause dermatitis and other symptoms.
