Embodiment 1

[0036] Embodiment 1 of the present invention is a kind of preparation method of nanofiber yarn, please refer to figure 1 , is a schematic diagram of the preparation of nanofiber yarns, which includes filament unwinding, electrospinning and nanofiber twisting. The preparation method of this nanofiber yarn comprises the following steps:

[0037] (1) Filament group unwinding

[0038] The bobbin 4 with vinylon thin filament 5 is placed on the creel 3, the linear density of the filament 5 is 1.5dtex, the number of bobbins 4 on the creel 3 is 30, and the front of the bobbin 4 is arranged in sequence from near to far. Guide wire hole 1, upper and lower rollers 6 and the second guide wire hole 2, the free end of the filament 5 on the bobbin 4 passes through the first guide wire hole 1, upper and lower rollers 6 and the second guide wire hole 2 successively, and the filament 5 Traction and unwinding by the top and bottom rollers 6 into the electrospinning equipment 7;

Embodiment 2

[0051] A kind of preparation method of nanofiber yarn, this preparation method has used the electrospinning equipment used in the embodiment 1 equally, and this preparation method comprises the following steps:

[0052] (1) Filament group unwinding

[0053] The bobbin 4 with vinylon fine filaments is placed on the creel 3, the linear density of the filament 5 is 1.5dtex, the number of bobbins 4 is 100, the filaments are drawn out through the first guide hole 1, and the array of the first guide holes 1 is parallel Arranged on the rollers, the length of the rollers is 40cm, the width of the first guide hole 1 array 2 is 70cm, 5 groups of filaments pass through the upper and lower rollers 6, and the rotation of the upper and lower rollers 6 drives the filament groups to unwind, and the filament unwinding speed is 20m / min.

[0054] (2) Electrospinning and spinning

[0055] The receiving plate of the electrospinning equipment is grounded, and the filament group is naturally suspen...

Abstract

The invention discloses nanometer fiber yarn and a preparation method thereof. The method includes the following steps that multiple filament rolls are arranged on a plurality of reels on a creel and dragged and backed off by an upper roller and a lower roller to enter a static spinning device; control parameters of the static spinning device are set; static spinning liquid is prepared; filament jetting is conducted, wherein a nozzle of the static spinning device is controlled to outwards push the spinning liquid so that fiber filaments can be adsorbed to surfaces of filaments; the filaments where fiber filaments are adsorbed are soaked in solvent to be dissolved; fiber filaments obtained after dissolution are twisted by a twisting barrel; twisted yarn is wound around the reels after passing through a groove drum. According to the preparation method, the nanometer fiber yarn is prepared through the static spinning technology, and the preparation method has the advantages of being easy to operate, strong in yarn plasticity, low in cost and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a nanofiber yarn and a preparation method thereof. Background technique [0002] The strength of single-fiber nano-filaments prepared by electrospinning is very poor, so it is impossible to directly apply traditional textile technology for knitting, weaving and braiding to single-fiber nano-filaments to prepare knitted fabrics, woven fabrics and braids. Most of the single-fiber nanofilaments are used in the production of non-woven membranes. In addition to being used in traditional textile processing technologies, nanofiber yarns can also be used in composite materials, filter media, gas separation, sensors, and tissue engineering. Therefore, the textile industry is paying more and more attention to the development of nanofiber yarns. The existing methods for preparing nanofiber yarns are based on the principle that nanofibers are bundled and twisted, and the methods include met...
