Abstract

The invention discloses a method for manufacturing medical nanometer fiber protective clothing fabric based on the electrospinning technology. According to the method, spunbond, or traditional fabricor other textile fiber materials is used as base fabric, by utilizing the electrospinning technology, in combination with a doping and modifying technology and a long-acting electret technology, nanometer fiber membranes with different functionality are sprayed to the surface of the base fabric, and then the medical nanometer fiber protective clothing fabric integrating a protective function, a comfort function, an anti-microbial function, an anti-static function, a heat conducting function and the like and combining thermal-wet comfort and protective safety is manufactured and obtained. The method mainly solves the problem that an existing protective clothing fabric is large in filtration resistance, and poor in air permeability and comfort, and the method has the technological features that the manufacturing technology is simple, cost is low, and functional finishing combination is easy. Compared with a traditional process of manufacturing the protective clothing fabric, such as a compact fabric technology, a coating technology and a composite microporous membrane technology, the method omits the procedures of spinning, machine weaving, coating and the like, greatly simplifies the technological process of forming the protective clothing fabric, and enables industrialized production to be easily achieved.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to a method for preparing nanofiber medical protective clothing fabric based on electrospinning technology. Background technique [0002] With the outbreak of the new coronavirus epidemic, people have paid great attention to medical protective textile materials. Among all kinds of protective fabrics, disposable medical protective clothing occupies a major market share due to its advantages of disposable and avoidance of cross-infection. Disposable medical protective clothing can effectively prevent the passage of aerosols, bacteria, viruses, etc., and realize the barrier effect on liquids, microorganisms and particles, which is an important guarantee for the safety of medical personnel. Many institutions and scholars at home and abroad are committed to improving the protective performance of fabrics, while ignoring the wearing comfort of protective clothing. The nanofiber medical prote...
