Performance detection
Considering that the antibacterial agent has better antibacterial effect on common bacteria such as escherichia coli and staphylococcus aureus, according to the application, firstly, the antibacterial performance of candida albicans is measured on curtain fabrics prepared in the embodiment and the comparative example according to GB/T20944.3-2008 (evaluation of antibacterial performance of textiles, section 3: vibration method), in addition, the antibacterial test is carried out after the curtain fabrics prepared in the embodiment and the comparative example are washed for 20 times, the reduction rate of the antibacterial rate before and after washing is counted, and the detection result is shown in the following table 1.
Referring to the test results in table 1 above, it can be seen that the curtain cloth prepared in the present application has excellent antibacterial performance and antibacterial durability, and when the nano silver is loaded on titanium dioxide, and when the water-insoluble tetramethyl ammonium bistrifluoro methanesulfonimide ionic liquid is further added in examples 4 to 5, the antibacterial performance and antibacterial durability are improved, and when the water-insoluble quaternary ammonium bistrifluoro methanesulfonimide ionic liquid is further added in example 6, the water-insoluble ionic liquid is added in example 5, compared with the water-soluble quaternary ammonium salt ionic liquid in example 6, the antibacterial performance and antibacterial durability are better, and probably because the water-insoluble quaternary ammonium salt spicy chicken liquid is more easily adsorbed and embedded into the porous dipeptide, the antibacterial synergistic effect of the antibacterial peptide is exerted. And in combination with the detection result of the embodiment 7, when nano silver is loaded on the titanium dioxide, and glutathione is not added, the antibacterial rate and antibacterial durability are also obviously reduced, and the addition of glutathione is beneficial to the uniform loading of nano silver on the porous titanium dioxide, so that the antibacterial property and antibacterial durability of the nano silver are improved.
In combination with the detection results of examples 1 and 8-10, when the porous titanium dioxide doped with zinc oxide is selected as the titanium dioxide in the application, the antibacterial durability is further obviously improved, and referring to the result of example 11, when the porous titanium dioxide is not doped with zinc chloride but PEO is added, the antibacterial durability is improved compared with that of example 1 but weaker than that of example 8, and when the porous titanium dioxide is not added with PEO in example 12, the antibacterial durability is improved compared with that of example 1 but weaker than that of example 8, so that the doping of zinc chloride is helpful to improve the antibacterial performance, and the addition of PEO is helpful to the construction of the pore structure. And by combining the detection results of examples 13-15, when the antibacterial agent is used for treating the base material in two modes of dipping and smearing, the antibacterial durability of the base material is obviously improved.
In combination with the detection results of example 1 and comparative example 1, it can be seen that the antibacterial effect is significantly reduced when only nano-silver composite modified titanium dioxide particles are selected, the antibacterial durability is also reduced, in combination with the detection results of comparative example 2, the antibacterial durability of titanium dioxide in comparative example 2 is significantly reduced when only nano-silver is supported and the titanium dioxide is not modified by polyethyleneimine and a silane coupling agent, and the antibacterial durability of titanium dioxide in comparative example 3 is improved but still reduced when only modified by a silane coupling agent.
In addition, the antibacterial properties of escherichia coli and staphylococcus aureus and the reduction rate of the antibacterial rate after 20 times of washing were measured according to the methods described above for the curtain fabrics of examples 1, 4, 8 and 13 and comparative examples 1 to 3 of the present application, the measurement results are shown in the following table 2, and the air permeability measurement was performed with reference to GB/T5453-1997 "measurement of air permeability of textile fabrics", and the measurement results are shown in the following table 2.
