[0032]Example 1:
[0033]A) Polypropylene (PP) fibers as a micron fiber raw material are sequentially released from the opening machine, combing and laying the machine (i.e., the net) (i.e., web curtain or delivery) The microfiber layer as an intermediate layer is obtained by the aforementioned raw material.
[0034]B) First dissolve the polymethyl methacrylate as a solvent in N, N-dimethylformamide, and heated at a water bath temperature of 80 ° C for 10 h, resulting in a mass percent concentration of methyl methacrylate to 20%. Polymethyl methacrylate spinning fluid;
[0035]C) Using a pin-free nozzle as an electrospinning nozzle, the polymethyl methacrylate spunbium obtained by step b is supplied to the electrospinning nozzle by the supply liquid, such as a peristaltic pump, and controls a single (also The velocity of each) electrospinning head is 0.1 mL / h;
[0036]D) The receiving reticle is provided under the receiving reticle as described in step a), such as providing a ground metal pla...
