Abstract
The present invention involves an online micro -nano -fiber multi -stage composite spinning device and method. By setting up a static spinning system on the fine gauze machine, a cross -scale online composite gauze of sub -micron fibers and micrive fibers is achieved.The surface orientation of the chemical fiber fiber long silk is twisted and twisted to form a stable orientation of the sub -micron fiber / long silk core gauze, and then covered with the micrometer short fiber to the gauze core layer, and finally forms a sub -micrive fiber / long fiber / short fiber multi -levelThe core composite yarn realizes the fine and stable regulation of the yarn structure, and the long wire with good mechanical properties as the skeleton has significantly reduced the break rate of the sub -micron fiber layer in the process of forming and improved processing efficiency.
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 method capable of batch spinning continuous submicron fibers, with simple operation and strong practicability. The diameter of the submicron fibers prepared by electrospinning is usually 100-1000 nm, the fiber size is small, the specific surface area is high, and the fiber morphology and composition can be regulated by the spinning process parameters and flexible selection of 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 crystal...
