Embodiment 1

[0022] Put a certain concentration of spinning solution in the liquid storage tank of the air bubble electrospinning equipment 2, apply a suitable voltage through the high-voltage power supply 1, adjust the distance between the receiving plate, use nylon fiber filament as the core material, and use 2 output devices to output Then compound, passing between the liquid storage tank and the receiving plate, the spinning solution is stretched under the action of the electric field to form nanofibers, which are deposited on the nylon fiber filaments drawn forward at a speed of 0.1m / min, and the surface The core material deposited with nanofibers is coagulated through a coagulation bath, and then output after being processed by five pressing rollers to obtain composite nylon long yarns coated with nanofibers on the surface.

[0023] Nylon fiber has high strength, strong elongation, excellent elasticity, and good wear resistance, but it is easy to absorb water, and has poor heat resist...

Embodiment 2

[0025] Put a certain concentration of spinning solution in the liquid storage tank of the air bubble electrospinning equipment 2, apply a suitable voltage through the high-voltage power supply 1, adjust the distance between the receiving plate, use silk and polyurethane fiber filament as the core material, and use 8 output Device compounding, 4 of which are used for silk output, and the other 4 are used for polyurethane fiber filament output, passing between the bubble reservoir and the receiving plate, the spinning solution is stretched under the action of the electric field to form nanofibers, Deposited on silk fibers pulled forward at a speed of 2m / min, the core material with nanofibers deposited on the surface was solidified through a coagulation bath, and then output after being processed by 15 pressing rollers to obtain a composite long yarn coated with nanofibers on the surface.

[0026] Silk fiber has good hygroscopicity, strength and elongation are relatively good amon...

Abstract

The invention discloses a method and device for preparing nano-composite yarns. The method for preparing the nano-composite yarns includes the following steps that core materials for preparing the composite yarns are pulled forwards at the speed ranging from 0.01m / min to 10m / min; nano-fibers are stretched through a bubble spinning device and deposited on the surfaces of the core materials; the core materials of which the surfaces are deposited with the nano-fibers are coagulated through coagulating bath, processed through a compression roller and then output. Compared with the prior art, the nano-fibers are deposited on the surfaces of the core materials through the bubble spinning device to form the nano-composite yarns, macromolecule nano-fibers are transferred outwards, the fibers good in strong stretching capacity, poor in contact comfort and low in cost are coated inside, and then real performance complementation and advantage enhancement are achieved. The nano-fibers generated in the bubble electrostatic spinning process are effectively deposited on the yarns passing through the middle portion when the nano-fibers are transferred to a receiving plate with opposite charges, operation is simple, cohesion performance of the yarns of which the surfaces are deposited with the nano-fibers through the coagulating bath is improved, the nanometer effect is well exerted, and therefore performance is improved.

Description

technical field [0001] The invention relates to a preparation method and device of a nanocomposite yarn, belonging to the technical field of special fiber preparation. Background technique [0002] At present, nanofibers have been widely used in biomedicine, textile industry, composite materials, etc. due to their high specific surface area, high surface activity, excellent electrical conductivity, and mechanical properties. Bubble electrospinning technology combined with mechanical principles and mathematical methods research Various phenomena in the spinning process are a revolution in spinning technology and a breakthrough in nanotechnology, which can continuously prepare nanofibers with high quality and high efficiency. Today, Siro spinning uses parallel feeding or parallel splitting to twist and combine fibers to spin yarn. The typical double-sided structure has significant economic benefits, good yarn quality, simple and convenient process modification, and a wide rang...
