Description

Technical Field

[0001] The utility model relates to an electrostatic spinning quality inspection device, in particular to a quality inspection device for electrostatic spinning nanofiber film formation, belonging to the technical field of electrostatic spinning. Background Art

[0002] Electrospinning is a highly efficient spinning technology that transforms polymer solutions into nanofibers by applying a high-voltage electric field. The polymer droplets split and sputter, creating nanofibers that overlap and bond on a collecting substrate, forming a randomly arranged nanofiber membrane. Nanofiber membranes not only offer advantages such as high porosity and small fiber diameter, but also allow functional particles to be directly added to the polymer solution, creating nanofiber functionalities with widespread applications in various fields.

[0003] Chinese patent application publication number CN114941189A discloses an electrospinning nanofiber membrane continuous twisting yarn device and its application. This invention produces nanofiber yarns with high orientation, uniformity, and stability, controllable fineness and twist, and no hairiness, yet excellent strength. These yarns meet yarn processing requirements and are suitable for continuous production. Functional nanofiber yarns can be produced by adding functional particles or using functional polymer materials to the electrospinning solution.

[0004] Although the nanofiber yarn in the above-mentioned patent has a high degree of orientation and is suitable for continuous production, the electrospinning nanofiber membrane device in the above-mentioned patent is not convenient for detecting the completed electrospinning. The electrospinning is directly collected after the production is completed, resulting in inconsistent electrospinning production quality. Therefore, a quality inspection device for electrospinning nanofiber membrane is proposed herein. Utility Model Content
