Abstract

The invention relates to a centrifugal spraying device for bidirectional sheath-core fibers. The centrifugal spraying device comprises a core rotating container, two core spraying tubes, a sheath rotating container and two sheath spraying tubes; a sheath material cavity is formed in the sheath rotating container, the core rotating container is located in the sheath material cavity, the bottom of the core rotating container is connected with one face of the bottom of the sheath rotating container, and the other face of the bottom of the sheath rotating container is perpendicularly connected with the top of a rotating rod; each core spraying tube comprises a core inlet, a core tube cavity and a core outlet; each sheath spraying tube comprises a sheath inlet, a sheath tube cavity and a sheathoutlet; each core outlet extends to the outside of the sheath rotating container through the sheath material cavity, the side circumference of the sheath rotating container and the corresponding sheath spraying tube. According to the design, not only can the spinning fibers of sheath-core structures be generated, but also online material supplement can be realized, and the stability and the product quality are high.

Description

technical field [0001] The invention relates to a centrifugal spinning device, which belongs to the technical field of textiles, in particular to a centrifugal spraying device for bidirectional skin-core fibers, and is particularly suitable for spinning fibers capable of producing skin-core structures. Background technique [0002] Nanofibers refer to ultrafine fibers with a diameter of tens to hundreds of nanometers, which are widely used in textile materials, tissue engineering scaffolds, drug delivery, filter media, artificial blood vessels, biochips, nanosensors, optics, composite materials and other fields. Methods for preparing nanofibers include stretching, microphase separation, template synthesis, self-assembly, electrospinning, centrifugal spinning, etc., wherein centrifugal spinning refers to the process of polymer melt or solution produced by a high-speed rotating device. Centrifugal force and shear force are thrown out of the pores to form fibers. [0003] The ...
