Abstract

The invention relates to an onlinemicro-nano fiber multistage core-spun composite spinning device and method. Cross-scale online composite yarn formation of sub-micro fibers and micro-fibers is realized by an electrostatic spinning system arranged on a spinning machine, the sub-micro fibers are firstly subjected to oriented deposition and twisting on the surfaces of chemical fiber filaments, oriented sub-micro fiber / filament core-spun yarn with stable structure is formed and then is applied to a yarn core layer by micro short fibers through covering, and sub-micro fiber / filament / short fiber multistage core-spun composite yarn is formed finally. Fine and stable regulation and control of the yarn structure are realized, and besides, the filaments with better mechanical properties are taken as aframework, so that end breakage rate of a sub-micro fiber layer in a yarn forming process is substantially reduced and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to an on-line micro-nano fiber multi-stage core-spun composite spinning device and method. Background technique [0002] Electrospinning is currently the only general-purpose method capable of spinning continuous submicron fibers in batches, with simple operation and strong practicability. The diameter of submicron fibers prepared by electrospinning is usually 100-1000nm, the fiber scale is small, the specific surface area is high, and the fiber morphology and composition can be adjusted by the flexible selection of spinning process parameters and polymers, making electrospinning submicron fibers Micron fibers have become a research hotspot in the field of fiber science and engineering, and are widely used in filtration, energy, biomedicine, catalysis, waterproof and moisture permeability, oil-water separation and other fields. However, due to the small diameter and low ...
