Water drop sensor fabric and production method thereof

Abstract

The invention provides a water drop sensor fabric which can achieve water drop detection on large-area irregular-shaped occasions. The water drop sensor fabric comprises warp yarns and weft yarns, wherein the warp yarns are made of non-conductive chemical fiber multi-filaments and conductive fibers, the conductive fibers are arranged on the fabric edge positions of the left side and the right side, and the non-conductive chemical fiber multi-filaments are arranged on a fabric body. The weft yarns are made of non-conductive chemical fiber multi-filaments and conductive multi-filaments, the non-conductive chemical fiber multi-filaments serve as main yarns to be interwoven with the two types of warp yarns to form a main fabric body, and the conductive multi-filaments serve as functional yarns, are arranged in the warp yarn direction at intervals of certain distances and alternatively break at the fabric edge positions close to the left side and the right side fro a certain distance. The invention further provides a production method of the water drop sensor fabric. The production method mainly comprises the four steps of laid-in yarn adding, drafting and denting, weaving and yarn shearing, is matched with a drafting, denting and weaving method after the laid-in yarn adding to enable the yarn shearing to be executed along laid-in yarns, is quick and efficient and can achieve large-scale production.

Description

technical field [0001] The invention relates to a fabric and a production method thereof, in particular to a water drop sensor fabric and a production method thereof, belonging to the field of textile technology and sensor technology. Background technique [0002] At present, there are some small water drop sensors on the market, which can be applied to smart curtains, car wipers, and other occasions that need to detect the presence or absence of water droplets. This type of water drop sensor is generally formed by plating two grid-shaped electrodes on a tiny circuit board. It uses the conductivity of water to work, and its performance is stable, which can meet the requirements of general occasions. However, the disadvantages of this type of water drop sensor are also obvious: it can only realize the detection of small area and fixed position, which is not suitable for some important occasions. For example, a modern computer room is equipped with many important information ...

AI Technical Summary

Problems solved by technology

This kind of water drop sensor fabric adopts a knitted structure, which is suitable for underwear. Due to the poor shape retention and firmness of the knitted fabric, it is not suitable for industrial occasions.
