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.

Embodiment 1

[0045] The present embodiment provides a preparation method of a continuous electrothermochromic fiber based on polyester filament, including the following steps:

[0046] 1. Preparation of polyester conductive filament by electroless deposition

[0047] 1) Wind the polyester filament on a reel with a diameter of 5cm for 20 minutes, then remove it from the reel. The fiber can maintain a ring shape. Treat the polyester filament with a standard solution of NaOH for 60 minutes to remove grease and impurities on the surface.

[0048] 2) Treat the surface of the polyester filament with a plasma cleaner for 5 minutes to improve its hydrophilic properties; then place it in an ethanol solution with a concentration of 2% (v / v) of vinyltrimethoxysilane (VTMS) for 15 minutes to make it Silane reacts with hydroxyl groups on the fiber surface.

[0049] 3) Using potassium persulfate as an initiator, put the VTMS-modified fibers into an aqueous solution of methacryloyloxyethyltrimethylammon...

Abstract

The invention discloses a preparation method of a continuous electrothermochromic fiber based on polyester filament, comprising: S1. winding the polyester filament into a ring shape, and removing grease and impurities on the surface; S2. using an electroless deposition process Deposit a metal copper coating on the surface of the polyester filament; S3. anneal the polyester filament to obtain a polyester conductive filament; S4. pass the polyester conductive filament through a tank equipped with temperature-sensitive color-changing ink, and then dry it through a heat device , wound on a roller to obtain a continuous electrothermochromic fiber; wherein, in step S2, a composite stabilizer is added to the electroless deposited copper plating solution, and the composite stabilizer is composed of potassium ferrocyanide and 2, 2'-bipyridine, the concentration of potassium ferrocyanide is 5-10mg / L, and the concentration of 2,2'-bipyridine is 5-10mg / L. The preparation method of the invention can realize the continuous production of electrothermally induced discoloration fibers, has low production cost, controllable fiber diameter, and high electrical conductivity of the obtained fibers.

Description

technical field [0001] The invention relates to the technical field of electrochromic fibers, in particular to an electrothermochromic fiber based on polyester filaments 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 have low wearability, huge cost, and cannot be mass-produced, so their practical application is not complete. , which greatly limits the industrial development of color-changing fibers. Therefore, it is of great scientific value to produce continuous smart color-changing fibers with excellent properties through low-cost processes. [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 microcapsules as ther...
