And (3) performance testing: we took 100cm before modification2Several nonwoven fabric patterns were measured, each mass was M1, and the modified 100cm2Several nonwoven fabric patterns were tested, each having a mass M2.
Setting the mass ratio C as follows: M2-M1/M1. And performing comparison test on the performance index and the appearance before and after the test.
1. Measurement of Water contact Angle:
the method for measuring the water contact angle is one of effective methods for representing the surface hydrophilic performance, when water is in contact with the outermost layer of the surface, the hydrophobic surface free energy is small, the measured contact angle is large, the hydrophilic surface is large in self-free energy, water drops are easy to spread, the measured contact angle is small, the surface water contact angle is reduced from 88 +/-2 degrees before modification to 38 +/-2 degrees after modification, and the hydrophilic performance of the surface of the non-woven fabric is obviously improved.
2. Comparing the microscopic appearances of the non-woven fabrics before and after modification:
the surface of the modified non-woven fabric is compounded with a compact PVA film, and PVA gel is filled among fibers in the non-woven fabric. This is advantageous for enhancing the mechanical properties of the nonwoven fabric.
3. Tensile strength and tear strength testing of the nonwoven:
as shown in fig. 3, the tensile strength gradually increases as the mass ratio C increases. As shown in fig. 4, the tear strength gradually increases as the mass ratio C increases. The tensile strength and the tearing strength of the modified non-woven fabric are respectively improved by 28 percent and 32 percent compared with the conventional non-woven fabric.
4. And (3) antibacterial property: the product fragments are immersed in the bacterial liquid, the surface of the detector is polluted, and the experimental result is as follows:
Figure DEST_PATH_IMAGE001
5. bacteriostasis: the European standards Committee (CEN) EN 1149-5 (2008 edition) specifies that the surface resistance of the product measured by the test method is only 1.2 x 109Ω/cm。
