Problems solved by technology

[0002] The flash evaporation method, also known as the instant solvent volatilization method, does not use melt spinning, but adopts dry spinning technology, that is, the high polymer is dissolved in a certain solvent to make a spinning solution, and then the spinneret hole Spraying, the high polymer is re-solidified into fibers due to the rapid volatilization of the solvent. At the same time, the dry spinning technology used in the flash method is different from the ordinary dry spinning technology, mainly reflected in the lower cost of the flash method. The viscosity of the spinning solution is high, and it is sprayed from the spinneret hole at a very high pressure and speed. Due to the low viscosity and good fluidity of the solution, the liquid filaments solidify during high-speed motion to form extremely fine fiber filaments, which are finally drawn Adsorbed on the web curtain to form a fiber web directly. With the development of flash spinning technology, the research on the solvent system and spinning process parameters of flash spinning has been in-depth. The performance of the product itself, especially the mechanical properties, can greatly meet people's needs, but its functionalization degree is relatively low. At present, the functionalization of flash nonwovens has not been widely studied.

preparation example Construction

[0025] The preparation method of the present invention is to remove a part of the personal protective clothing, cut it into long strips with the same specifications, polish it with a fine steel brush and stick it on the receiving plate for receiving nano-micron porous luminescent fibers, and then electrospin The parameters of the device are fully adjusted, and the external conditions are adjusted to meet the conditions for obtaining nano-micron porous fibers. As the electrospinning proceeds, the surface of the flash nonwoven fabric is continuously adhered to the nano-micron porous luminescent fiber. When the nano-micron porous luminescent fiber is punched to a certain thickness, the flash nonwoven fabric can be removed to obtain the obtained product of the present invention. product of. It can be applied directly after gluing or roller pressing.

Embodiment example 1

[0027] Implementation case 1: figure 1 In order to receive the flash non-woven fabric sample strip of electrospun nano-micro porous luminescent fiber, the specific method is to cut the flash non-woven fabric into a certain width and length of the spline, and then fix it on the receiving screen , for accepting electrospun fibers. As the electrospinning proceeds, a layer of nano-microporous luminescent fibers can be received on the flash nonwoven fabric.

Embodiment example 2

[0028] Implementation case 2: figure 2 For the nano-micro porous luminous fiber prepared by electrospinning, the specific method is to paste a layer of tin foil paper on the receiving screen, and the electrospun nano-micro porous luminescent fiber will adhere to the surface of the tin foil paper after solidification. The silver-white one in the figure is Tin foil paper, the white one is a film made of nano-micron porous luminescent fibers.
