A kind of preparation method of flexible conductive yarn

Abstract

The invention relates to a preparation method of flexible conductive yarn, which belongs to the technical field of intelligent fabrics. In the present invention, natural silk is carbonized as the base of the conductive yarn. The carbonized silk fiber has a honeycomb structure, a large specific surface area, a high nitrogen content and a high graphitization process. The conductive yarn prepared has good conductivity, silk has the advantages of high comfort and flexibility, silver nanowire has excellent flexibility, low preparation cost, simple operation process, and is packaged with butadiene rubber, which is the current rubber The medium elasticity is the best, the medium and low temperature performance is better, the hysteresis loss is small, and the flex resistance is excellent; the electrospinning method is used to use the polymer solution or solution to form a jet under the action of an electrostatic field, so that it is subject to draft changes in the electric field After curing, the micro-nanostructured fibers are formed to prepare flexible and stretchable conductive yarns.

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.
