Abstract

A sheath core fiber centrifugal spinning system comprises a ventilation ring disk, a bottom recessed disk, a core rotating container, a core injection pipe, a sheath rotating container, a sheath injection pipe and a collecting rod. The core rotating container is positioned in the sheath rotating container, the sheath rotating container and the bottom recessed disk are positioned on the upper portion and the lower portion of an inner disk cavity in the ventilation ring disk, the core injection pipe and the sheath injection pipe are connected with the core rotating container and the sheath rotating container, the sheath injection pipe externally sleeves the core injection pipe, and the bottom end of the rotating rod connected at the bottom of the sheath rotating container sequentially penetrates the inner disk cavity and the bottom recessed disk and extends to the lower portion of the bottom recessed disk. According to the design, a spinning fiber with a sheath core structure can be generated, materials can be supplied on line, product quality is high, guidance and adjustability are high, and collecting effects are good.

Description

technical field [0001] The invention relates to a centrifugal spinning technology, which belongs to the field of textile technology, and in particular to a centrifugal spinning system for sheath-core fibers, which is particularly suitable for obtaining and collecting spun fibers with a sheath-core structure by means of centrifugal spinning . 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...
