Preparation method of flexible conductive yarn

Abstract

The invention relates to a preparation method of a flexible conductive yarn and belongs to the technical field of intelligent fabrics. According to the preparation method of the flexible conductive yarn, natural silk is carbonized to serve as the matrix of the flexible conductive yarn, and carbonized silk fiber has the advantages of a honeycomb structure, a large specific surface area, high content of nitrogen, high degree of graphitization and the like; a prepared silver nanowire is compounded with the carbonized silk, so that the prepared f flexible conductive yarn can achieve high electricconductivity; the silk has the advantages of high comfort level, high flexibility and the like, the silver nanowire is excellent in toughness, and the preparation method of the flexible conductive yarn is low in cost and simple in operation process; the prepared flexible conductive yarn is packaged with butadiene rubber, which has the best elasticity among existing rubbers and is good in medium and low-temperature performance, low in hysteresis loss and excellent in warping strength; by means of an electrostatic spinning method, polymer solution or melt can form a jet flow under the action ofan electrostatic field and accordingly can be stretched and cured in the electrostatic field into a fiber in a micro-nano structure for preparing the flexible and stretchable conductive yarn.

Description

technical field [0001] The invention relates to a preparation method of flexible conductive yarn, which belongs to the technical field of intelligent fabrics. Background technique [0002] With the development of the times and the advancement of science and technology, the textile industry has also undergone transformation and evolution again and again, and the functions of yarns have also been slowly developed, and are no longer solely used for clothing decoration. For example, in recent years, with the birth and popularization of high-end electronic products such as ipad and other capacitive touch products, as well as the shortcomings of the bulky batteries of the old version, experts in the textile industry have focused on researching how to integrate them into clothing as a capacitor or a sensing device to replace bulky capacitors. The device may have conductive yarns that accumulate energy, eliminate static electricity, antibacterial, deodorant, and intelligent heating....

AI Technical Summary

Problems solved by technology

Compared with soft yarns such as cotton thread and polyester, metal fiber is still relatively rigid. In addition, the long-term folding process of clothes will inevitably lead to the breakage of the metal wire, which will cause unnecessary damage to the human body. If these yarns are used There are also contact problems in making wires, and the application is limited. The flexibility, washability and durability of conductive yarns in the structural form need to be further improved.
