Problems solved by technology

However, the equipment and accessories required by the meltblown method are expensive and consume a lot of energy.
You can also use the manual pressure spraying method, which can form filaments without beading, but the thickness of the filaments is uneven, which has a great impact on wind resistance

Abstract

The invention discloses a composite polymer functional fiber, a preparation method thereof and pressure spraying equipment for preparing the composite polymer functional fiber. The composite polymer functional fiber comprises a protective layer, a spinning layer and a supporting layer which are arranged in sequence; the spinning layer comprises a composite polymer fiber, and the composite polymer fiber comprises a polymer and a nano material doped in the polymer; the protective layer is selected from shaping yarns and / or patterned plain cloth; and the supporting layer is selected from fibers with a net structure. The fiber has a support layer-spinning-protective layer sandwich structure, is stable in structure, uniform in fiber and controllable in size, and can be used for a filter screen or a sewage filter membrane of atmospheric haze particulate matters and the like.

Description

technical field [0001] The invention belongs to the field of fiber materials, and in particular relates to a composite polymer functionalized fiber, a preparation method thereof and pressure spraying equipment used for the preparation thereof. Background technique [0002] Electrospinning technology has become one of the main ways to effectively prepare nanofiber materials due to its simple manufacturing equipment, low spinning cost, various types of spinnable materials, and controllable process. Fiber membranes with different structures and sizes can be obtained by adjusting the nozzle structure of the spinning equipment and controlling the experimental conditions. At present, electrospinning technology can be used to prepare a wide variety of functional fibers with controllable size, including organic, organic / inorganic composites and inorganic nanofibers. However, there are still some limitations in the preparation of functionalized fibers by electrospinning technology. ...
