Test example 1
The nonwoven fabrics obtained in examples 1 to 3 of the present invention and comparative examples 1 to 8 were subjected to performance tests, and the results are shown in Table 1.
Water absorption performance: the nonwoven fabrics obtained in the examples and comparative examples were subjected to a water absorption test with reference to GB/T24218, cut into circles having a diameter of 100mm, and soaked in water at room temperature for 48 hours, and then water absorption was measured.
Antibacterial property: the inhibition rate of the nonwoven fabric obtained in each example and the comparative example on Escherichia coli under the same conditions was measured. At a concentration of 5X 10 6 The method comprises the following steps of uniformly smearing cfu/mL escherichia coli in a plurality of groups of culture dishes with diameters of 100mm and containing nutrient agar, cutting sample pieces with the radius of 3cm from each group of non-woven fabrics, respectively paving the sample pieces in the centers of the culture dishes, placing each group of culture dishes in a constant temperature box with the temperature of 35 ℃ for culturing for 72 hours, and measuring the number of bacterial colonies on each non-woven fabric sample piece. And replacing the non-woven fabric with sterilized water as a control experiment, and measuring the number of colonies in a control group. The bacteriostatic ratio (%) (1-number of colonies in sample group/number of colonies in sample group) x 100%.
TABLE 1
As can be seen from the data in table 1, the nonwoven fabric prepared in this example has good water absorption performance and antibacterial effect.
Comparative example 1 is different from example 1 only in that the raw material consists of polypropylene and super absorbent antibacterial microspheres. Because the polypropylene is not treated by plasma, the compatibility between the polypropylene and the high-water-absorptivity antibacterial microspheres is poor, the microspheres are seriously agglomerated, the surface area in contact with water is greatly reduced, and the water absorption rate is reduced. The quaternary ammonium salt ions do not sufficiently contact with escherichia coli, and the antibacterial effect is also deteriorated.
The difference between the comparative example 2 and the example 1 is that in the preparation route of the antibacterial microsphere with high water absorbability, the treatment without adding the trimethylamine aqueous solution causes that quaternary ammonium salt ions do not exist in the system and the antibacterial effect is poor.
In comparative examples 3 and 4, the most used emulsifier proportion is not selected, so that the obtained water-in-oil emulsion is not stable enough, the prepared microsphere has an incomplete structure, part of quaternary ammonium salt ions enter the shell, and the antibacterial effect is poor.
In comparative examples 5 and 6, there is no synergistic effect of water absorption of polyacrylic acid and polyethylene glycol, so the water absorption rate is low compared to example 1. .
The comparative example 7 is different from the example 1 only in that the mass of the cross-linking agent of the ethylene glycol dimethacrylate is changed to 4g in the preparation route of the antibacterial microsphere with high water absorbability, and water absorption rate is reduced because water cannot enter the inner cavity due to too high degree of cross-linking of the shell layer.
The comparative example 8 is different from the example 1 only in that in the preparation route of the antibacterial microsphere with high water absorbability, the cross-linking agent of the ethylene glycol dimethacrylate is not added, the shell layer of the prepared antibacterial microsphere is damaged, and the quaternary ammonium salt ions are covered and cannot fully exert the antibacterial effect.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
