Abstract

The invention discloses a preparation method of continuous electric thermochromic fiber based on polyester filament yarn. The method comprises the following steps of S1, winding the polyester filament yarn in a ring shape, and removing grease and impurities on the surface of the polyester filament yarn; S2, depositing a metal copper plating layer on the surface of the polyester filament yarn through an electroless deposition process; S3, carrying out annealing treatment on the polyester filament yarn to obtain polyester conductive filament yarn; and S4, enabling the polyester conductive filament yarn to pass through a groove filled with thermochromic ink, drying the polyester conductive filament yarn through a heating device, and winding the polyester conductive filament yarn on a rolling shaft to obtain the continuous electric thermochromic fiber, wherein in the step S2, a compound stabilizer is added into a copper plating solution of electroless deposition, the compound stabilizer is composed of potassium ferrocyanide and 2,2'-dipyridyl, the concentration of the potassium ferrocyanide is 5-10 mg/L, and the concentration of the 2,2'-dipyridyl is 5-10 mg/L. The preparation method provided by the invention can realize continuous production of the electric thermochromic fiber, the production cost is low, the fiber diameter is controllable, and the obtained fiber has high conductivity.

Description

technical field [0001] The invention relates to the technical field of electrochromic fibers, in particular to an electrothermochromic fiber based on polyester filament and a preparation method thereof. Background technique [0002] With the increasing application of smart textiles, color-changing fiber technology has also developed rapidly. However, color-changing fibers are not wearable, costly, and cannot be mass-produced, so they are not complete in practical applications. , which greatly limits the industrial development of color-changing fibers. Therefore, it is of great scientific research value to produce continuous intelligent color-changing fibers with excellent properties through a low-cost process. [0003] Electrothermochromic fibers refer to fibers that can reversibly change color under the condition of applying a certain voltage, presenting an adjustable visual change. Its structure and process are relatively simple, and the preparation process of microcapsu...

Problems solved by technology

But the shortcomings are also obvious. They developed electrothermochromic fabrics, which have certain limitations in application and are difficult to produce in large-scale continuous production, and because the conductive material is graphene, the cost is high and it is difficult to achieve continuous production.
