Conductive yarn and production method thereof

Abstract

The invention relates to a conductive yarn, made by wrapping a yarn with a metal nano-wire and carbon nanomaterial, and a production method thereof. The method includes: soaking a yarn in metal nano-wire solution and evaporating and drying, or repeating the step, to obtain the metal nano-wire wrapped conductive yarn; or soaking the metal nano-wire wrapped yarn in carbon nanomaterial solution and evaporating and drying, or repeating the step several times, to obtain the conductive yarn wrapped with the metal nano-wire and the carbon nanomaterial material; or soaking a yarn in metal nano-wire and carbon nanomaterial mixed solution and evaporating and drying, or repeating the step several times, to obtain the conductive yarn wrapped with the carbon nanomaterial and the metal nano-wire. The production method is very simple, easy for industrialized production and applicable to production of textile electronic devise, and has very promising application prospect.

Description

technical field [0001] The invention relates to a conductive yarn wrapped with metal nanowires and carbon nanomaterials on the yarn and a preparation method thereof. Background technique [0002] With the development of science and technology, future electronic products will be flexible, portable and wearable through printable methods, which puts forward intelligent requirements for textiles, that is, smart textiles. Smart textiles will be a landing point for the future electronic information industry, as well as the future development direction and important economic growth point of the textile and garment industry. Among them, conductive yarn is the basic raw material of smart textiles and interactive fabrics, which can be used for sensor connection lines, power electrodes and connection lines, radio frequency circuits, electromagnetic shielding, etc., and has important uses in industrial, civil and military fields. Excellent conductive yarns need to have good conductivit...

Problems solved by technology

For example: In 2007, Baoding Yimian Group Co., Ltd. prepared conductive fibers with conductive, anti-wrinkle, and bactericidal effects by mixing polyester, ramie, bamboo fiber, and carbon fiber (public number: CN101182662); in 2009, the school legal person Ritsumeikan; Our company winds the core yarn made of elastic yarn by winding the winding yarn with conductive function, and the clothes made of this yarn can be used to measure biological information (public number: CN101728005A); 2013 Zhejiang Chunjiang Textile Group Co., Ltd. has prepared highly conductive yarns by twisting stainless steel fibers and cotton fibers together. This yarn is widely used in antistatic clothing (public number: CN203096285U); these yarns Although the problem that the stainless steel metal fiber "joint" is easy to puncture the skin has been technically overcome, the metal fiber is still relatively rigid compared to soft yarns such as cotton and polyester. In addition, the clothes will inevitably be damaged during the long-term folding process. Leading to the breakage of metal wires, thus causing unnecessary harm to the human body, if these yarns are used as wires, there are also problems in contact
