Embodiment 1

[0040] (1) The polyacrylonitrile yarn grafted with fluorosilane and the conductive yarn are plied and twisted to obtain a primary spiral yarn of 800 twists / m, and then two primary spiral yarns are plied and twisted to obtain a 600 twist / m multi-stage spiral yarn, the directions of the two twists are opposite.

[0041] (2) Insert the conductive yarn into the rubber tube, stretch the rubber tube, use the friction between the rubber tube and the conductive yarn and the compression force at both ends of the rubber tube to make the conductive yarn present a serpentine structure in the rubber tube, and then Two-component epoxy glue was used to seal both ends of the rubber tube to obtain triboelectric yarns.

[0042] (3) Using the multi-stage helical yarn in step (1) as the warp yarn and the triboelectric yarn in step (2) as the weft yarn, plain weave is performed using a knitting machine. First, adjust the position of the heald frame, and set the parameters on the writing board sc...

Embodiment 2

[0050]In embodiment 1 step (1), "obtain the primary spiral yarn of 800 twist / m" to "obtain the primary spiral yarn of 600 twist / m", change "obtain the multistage spiral yarn of 600 twist / m" In order to "obtain a multi-stage spiral yarn of 450 twist / m", change the "working air pressure to 0.6MPa, and the picking amount per minute to 70 times" in step (2) to "the working air pressure is set to 0.5MPa, every The amount of picking per minute is set to 60 times", and the rest are the same as in Example 1 to obtain energy harvesting textiles.

[0051] Figure 10 It shows that the twist of the multi-stage helical yarn is reduced, and the output performance of the energy harvesting textile is reduced.

Embodiment 3

[0053] In embodiment 1 step (1), "obtain the primary helical yarn of 800 twist / m" to "obtain the primary helical yarn of 400 twist / m", "obtain the multistage helical yarn of 600 twist / m" into "Obtain a multi-stage spiral yarn with 300 twist / m", change the "working air pressure is set to 0.6MPa, and the picking amount per minute is set to 70 times" in step (2) to "the working air pressure is set to 0.4MPa, every minute The amount of picking was set to 50 times, and the rest were the same as in Example 1 to obtain energy-harvesting textiles.

[0054] Figure 11 It is shown that as the twist of the multi-stage helical yarn decreases, the yarn bonding becomes loose and the output performance of the energy harvesting textile decreases.

Abstract

The invention relates to a multifunctional biomechanical energy collection textile, a preparation method and application thereof. The method includes: preparing multi-stage spiral yarns by plying and twisting, inserting conductive yarns into rubber tubes, stretching the rubber tubes to prepare triboelectric yarns, using multi-stage spiral yarns as warp yarns, and triboelectric yarns as weft yarns , Fabrication of Energy Harvesting Textiles by Plain Weaving. The energy-harvesting textile has good stretchability and hydrophobicity, which can be used to power electronic devices, and can also be used as an energy source and sensor for a self-powered wireless monitoring system.

Description

technical field [0001] The invention belongs to the field of wearable energy and its preparation and application, in particular to a multifunctional biomechanical energy collection textile and its preparation method and application. Background technique [0002] The rapid development of wearable electronic products is causing changes in human social life, and people's demand for wearable energy is increasing. However, conventional rechargeable batteries are difficult to meet the requirements of light weight, flexibility, and integration of wearable electronic devices due to their limited capacity, poor flexibility, poor stretchability, and poor biocompatibility. Therefore, the development of sustainable and self-powered systems is of great importance for wearable electronics. Biomechanical energy is one of the most common and abundant mechanical energy that humans can generate every day, and harvesting wasted biomechanical energy from human motion can help address the energ...
