Aerogel-doped high-temperature-resistant power generation spinning yarn as well as preparation method and application thereof

Abstract

The invention discloses aerogel-doped high-temperature-resistant power generation spinning yarn and a preparation method and application thereof.The power generation spinning yarn comprises a nanofiber shell and a yarn core, the nanofiber shell is provided with an axial cavity, the yarn core is located in the axial cavity, and the length of the nanofiber shell is smaller than or equal to that of the yarn core; the nanofiber shell is made of a first dielectric material doped with aerogel nanopowder, and the yarn core comprises a first yarn core wire made of a second dielectric material and a second yarn core wire made of conductive fibers; and the second dielectric material and the conductive fiber are respectively contacted with the inner wall of the axial cavity. According to the preparation method, an electrostatic spinning technology is adopted for preparation, and the fabric is used for manufacturing braided fabrics. The problems that an existing high-temperature protective garment is too heavy and poor in breathability can be solved; meanwhile, the high-temperature-resistant power generation spinning can convert kinetic energy into electric energy and can be used for manufacturing intelligent high-temperature protective clothing.

Description

technical field [0001] The invention relates to the technical field of power spinning. Specifically, it relates to an airgel-doped high-temperature-resistant electric spinning and its preparation method and application. Background technique [0002] Human activities and industrial development have played an unparalleled role in pursuing the needs of modernization and progress of civilization. Industrialization and human activities, under the expectation of perfecting the existing human resources, will inevitably lead to accidents in laboratories, chemical plants or other high-risk areas, such as steel plant accidents and special workshop accidents, the most common accidents in these events It is thermal burns, flame spread and sparks flying that can cause severe burns and even casualties to personnel. The increase in casualties of such accidents is due to improper safety measures and prevention. According to incomplete statistics, about 33% of the seriously injured people...
