Fabric resistance sensor and preparation method thereof

Abstract

The invention provides a fabric resistance sensor which is divided into three layers from the top to the bottom, including a first layer of fabrics, a second layer of fabrics and a third layer of fabrics respectively. The yarn used by the second layer of fabrics is a polyaniline composite conductive yarn and a spandex monofilament. The invention also provides a preparation method of the fabric resistance sensor. The yarn preprocessed by atmospheric pressure plasma is adopted to act as base material, and aniline monomers, oxidizing agent and the doped acid are oxidized and polymerized on the surface of the yarn to form polyaniline and thus a polyaniline composite conductive yarn is formed, and the polyaniline composite conductive yarn and the spandex monofilament are braided together to act as the second layer of fabrics. Fabric layers prepared by common yarns are respectively braided above and below the second layer of fabrics. The fabrics are enabled to possess advantages of soft hand feeling and great comfort performance by the fabric sensor with the three-layer sandwich structure. Besides, multiple shapes of fabric sensors can be manufactured so that the fabric resistance sensor has the advantage of flexible and variable modeling.

Description

technical field [0001] The invention relates to the technical field of application of new textile materials, in particular to a fabric resistance sensor and a preparation method thereof. Background technique [0002] A sensor is a widely used detection device that can transform the sensed measured information (including physical information, chemical information, biological information, etc.) or other required forms of information) output to meet the requirements of information transmission, processing, storage, display, recording and control. In recent decades, the rapid development of modern measurement, control and automation technology has made people more and more aware of the importance of sensor technology. Especially in recent years, due to the needs of economic development, scientific and technological progress, and ecological environment protection, the important role of sensors in various fields has become increasingly prominent. At present, sensor technology is...
