Preparation method of velvet-shaped night indication woven belt capable of generating power

Abstract

The preparation method comprises the following steps: by taking chinlon multifilament as ground warp and piezoelectric monofilament as wool warp, weaving warp yarns, chinlon weft yarns and conductive weft yarns into the woven belt with looped piles according to towel tissues, cutting the piezoelectric monofilament into piezoelectric short fibers, and performing indentation treatment to enable the piezoelectric short fibers to protrude out of the surface of the woven belt, thereby obtaining the power-generating velvet woven belt for night indication. Connecting the conductive weft yarns with the LED lamp beads to obtain a woven belt; the piezoelectric monofilament is rectangular on the whole and comprises an elastic wrapping layer II, a piezoelectric film II and a conductive yarn II; the piezoelectric film II is fixed in the elastic wrapping layer II, and the section of the piezoelectric film II is wave-shaped; the central axis of the conductive yarn II is parallel to the length direction of the piezoelectric monofilament, is in contact with the trough area of the piezoelectric film II and is partially exposed out of the elastic covering layer II, and the conductive yarn II is spread all over the upper and lower surfaces of the piezoelectric film II; the areas, exposed out of the conductive yarns II, of the piezoelectric monofilaments are in contact with the conductive wefts; the method disclosed by the invention is simple, and the prepared product can generate voltage through the deformation of the piezoelectric short fibers.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a preparation method of a velvet night-indicating woven belt capable of generating electricity. Background technique [0002] The use of natural energy sources, such as solar energy, thermal energy, mechanical energy, wind energy and tidal energy, to obtain electrical energy has become an important research direction in the energy field. The application of smart materials to the wearable field is also attracting the attention of more and more researchers. In the field of smart wearables, how to obtain electricity without using a power source has become an indispensable content. The device allows users to not compromise the use experience due to power consumption, especially in military, field use and many occasions where power cannot be used. As a material that can convert mechanical energy into electrical energy, piezoelectric materials are undoubtedly an indispensable part of t...

Problems solved by technology

During the day, due to sufficient light, various ribbon fabrics are easily perceived by the human eye and can play a very good prompting effect, but at night, the functional webbing that enables people to obtain information through luminous means cannot play its role well. In order to make the webbing glow, it is usually necessary to add a light-emitting element to it, and also need to be equipped with a power supply device. A webbing without a power supply cannot provide energy to the light-emitting element at night

For some occasions with external light sources, reflective forms can be used to make the naked eye aware, but areas with insufficient light often cannot provide clear enough information to allow people to make correct and effective judgments

Adding a power supply to this type of ribbon fabric will not only increase the cost, but also greatly weaken its flexibility and portability.
