Abstract

The embodiment of the invention relates to a head unit, an electrospinning head and an electrospinning apparatus, and provides a head unit, an electrospinning head and an electrospinning apparatus which are capable of inhibiting a structure, controlling the complexity of the control system, the increasing of the manufacturing cost and reducing the production rate and properly forming the film of afiber with a large size in the width direction. According to the embodiment, the electrospinning head comprises a plurality of head units and a coupling structure, and the plurality of head units arecoupled to one another through the coupling structure. Each head unit includes a unit main body and a nozzle. Inside the unit main body, a hollow storing a raw material liquid is formed along a longitudinal axis. The nozzle is formed of a conductive material and provided on an outer circumferential surface of the unit main body. The nozzle ejects the raw material liquid supplied through the hollow of the unit main body. The coupling structure connects the plurality of head units in a state where the hollows of the unit main bodies communicate with one another.

Description

Technical field [0001] The embodiment of the present invention relates to a nozzle unit, an electrospinning nozzle, and an electrospinning device. Background technique [0002] There is an electrospinning device in which fine fibers are deposited on the surface of a collector or a substrate by an electrospinning method (sometimes called an electrospinning method or a charge induction spinning method) to form a fiber membrane. The electrospinning device is provided with an electrospinning nozzle having a nozzle body and nozzles. In the electrospinning nozzle, a cavity (head flow path) for accommodating the raw material liquid is provided inside the nozzle body, and nozzles are provided on the outer peripheral surface of the nozzle body. Furthermore, by applying a voltage between the electrospinning nozzle and the collector or the substrate, the raw material liquid is ejected from the nozzle outlet toward the surface of the collector or the substrate, and the fibers are deposited ...
