Embodiment Construction
[0006] The preparation technology of the described PA6 nanofiber membrane has four basic processes: 1. Mix formic acid and glacial acetic acid, add PA6 slices, the mass percentage of PA6 is 11%, stir with an electromagnetic stirrer to obtain a uniform and transparent spinning solution ; 2. Use PP non-woven non-woven fabric with a width of 30cm as the receiving substrate, and the receiver speed is 2m / min; 3. Send the prepared spinning solution to a roller-type electrospinning machine for spinning, and the rotor speed is 20rpm. The generator distance is 180mm, and the voltage is 75KV; 4. Through continuous spinning, rolls of PA6 electrospun nanofiber membranes are obtained. The PA6 electrospinning nanofiber preparation technology will make this new material widely used in the filtration industry, with remarkable economic and social benefits.

The technology for preparing the PA6 nanofiber membrane is characterized in that PA6 slices serve as raw materials, PP nonwoven cloth serves as base materials, the PA6 slices are dissolved in spinning solution made of formic acid and acetic acid mixed solvents, and the PA6 nanofiber membrane is prepared through continuous spinning by using a roller type electrostatic spinning machine. By the adoption of the arrangement, the production efficiency of the nanofiber membrane is high, and the nanofiber membrane has high adsorptive property, good filtration performance and barrier property. The technology for preparing the PA6 nanofiber membrane is mainly applied to filter materials, membrane materials and the like.
Description
technical field [0001] The invention relates to the field of new chemical materials, in particular to a preparation technology of PA6 nanofiber membrane. Background technique [0002] The surface effects of electrospun nanofibrous materials, such as high surface activity, high surface energy, and high specific surface area, have shown great potential in the preparation of high-performance filter materials. The nano-scale fiber non-woven film is obtained by electrospinning, the film is soft, and the thickness can be adjusted according to needs. However, the nanofiber felt has low strength and poor mechanical properties, and needs to increase the substrate to improve the strength; at the same time, there are many other problems to be solved, such as electrospinning equipment, which has some deficiencies more or less, and has not realized industrialization and scale . [0003] Nylon 6 fiber is one of the main varieties of synthetic fibers. It has good mechanical properties, a...
