Abstract

The invention discloses a nested spinning body. The spinning body comprises a plurality of liquid storage chamber sets, a plurality of first discharge holes, a plurality of second discharge holes and a plurality of injection pipe sets, wherein the plurality of liquid storage chamber sets are composed of first liquid storage chambers and second liquid storage chambers; the plurality of the first discharge holes are formed in the side walls of the first liquid storage chambers, and plurality of the second discharge holes are formed in the side walls of the second liquid storage chambers; one ends of the plurality of injection pipe sets are communicated with the first discharge holes and / or the second discharge holes, and the other ends of the injection pipe sets are placed in the side walls of the second liquid storage chambers or the outer parts of the side walls, therefore, a spinning solution A is injected by the first discharge holes and the injection pipe sets, and / or a spinning solution B is injected by the second discharge holes and the injection pipe sets and are collected by thread gathering equipment, and can be twisted and coiled to be yarns. The nested spinning body provided by the invention is applied to centrifugal and static-centrifugal spinning systems, so as to meet the demands of producing the mixture single-component nanofiber, bi-component or multi-component composite nanomicron fibers at high speed, low cost and large scale.

Description

technical field [0001] The invention belongs to the technical field of spinning, in particular to a nested spinning body. It is used in centrifugal and centrifugal-electrostatic nano and micro fiber spinning systems. Background technique [0002] Nanofibers are fibrous materials with diameters below a few hundred nanometers. Nanofibers have extremely high specific surface area and aspect ratio. Nanofibers can be divided into single-component, bi-component and multi-component nanofibers according to the cross-sectional structure. Monocomponent nanofibers are fibers composed of one material or a homogeneous mixture of several materials. Two-component nanofibers and multi-component nanofibers refer to composite nanofibers that each fiber is composed of two or more component materials in a certain special domain structure on its cross-section, in which two or more components can be Have different physical properties and or different chemical properties. Recently, a large nu...
