Description

Technical Field

[0001] This invention relates to the field of spinning technology, specifically to a process for preparing copper ion nano-spinning. Background Technology

[0002] Spinning is a process that uses mechanical force to twist fibers (or yarns) into fine, soft yarns with certain strength and elasticity, used for weaving, rope making, belt making, and thread spinning. Nano copper ion antibacterial yarn is a new type of spinning product manufactured using nanotechnology. Copper ions have a significant ability to inhibit bacterial growth, and this antibacterial property can last for a long time, effectively avoiding the loss of antibacterial effect of traditional antibacterial yarn over time. The production process of nano copper ion antibacterial yarn mainly involves two aspects: the selection of fiber materials and the spinning of yarn.

[0003] In practical applications, the spinning solution needs to be extruded through a spinning machine, and the mixed solution is sprayed into copper ion nanofibers. Therefore, a spinning machine is required. The spinning machine needs to spray the spun fibers through a spinneret. The spun fibers are solidified by a hot airflow. The hot airflow contains water vapor, which forms tiny pores inside the fiber and changes the fiber structure. This leads to changes in the fiber's mechanical properties, thermal stability, and corrosion resistance. At the same time, the presence of water vapor can clog the spinneret orifices. To address this, we propose a copper ion nanofiber spinning process. Summary of the Invention

The present invention addresses the technical problems mentioned in the background section by making corresponding improvements, including the following steps:

[0038] A. Mix copper ion solution with nanocellulose suspension to obtain a conductive nanospinning precursor. During this process, it is important to ensure that copper ions and nanocellulose are fully dispersed to avoid fiber agglomeration.

[0039] B. Using a wet spinning machine, the pretreated yarn is immersed in the spinning solution, and the spinning solution is extruded through the spinning machine. The mixed solution is sprayed into copper ion nanofibers.

[0047] Please see Figure 1 , 2 9, 10 and 11, the present invention provides a technical solution: a copper ion nano-spinning preparation process. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The separation and removal mechanism 2 also includes a separation unit 22, which is located between the removal unit 21 and the spinneret 11 and is used to separate water vapor.

[0048] As a further definition of the separation and suction mechanism 2 of the present invention, the separation unit 22 includes an air guide pipe 2201.

The gas guide pipe 2201, the separation pipe 2203 and the transmission pipe 2207 form a cross-branching arrangement. With the use of polysulfonamide membranes 2208, water vapor can be selectively separated, while other gases have good barrier performance. At the same time, the upper connecting pipe 2202 and the lower connecting pipe 2206 can guide the separated water vapor.

Under the polysulfonamide membrane 2208 set between the transmission pipe 2207 and the lower connecting pipe 2206, the water vapor will be separated again, and the hot air will enter the interior of the side pipe 2205. Then, the water vapor will be separated three times under the polysulfonamide membrane 2208 set at one end of the separation pipe 2203, so that the water vapor enters the interior of the water collection tank 31 through the separation pipe 2203 and the lower connecting pipe 2206. Then, the water vapor will be condensed into water droplets by the operation of the condenser 34, and finally discharged to the outside through the water outlet pipe 32.
