TABLE 1 measurement results of moisture permeability and moisture regain of the bamboo-like fiber fabrics prepared in examples 5 to 12 before and after washing the fabrics 50 times
As can be seen from table 1, the moisture permeability and moisture regain of the bamboo-like fiber fabrics prepared in examples 5 to 12 after being washed 50 times do not change much, and thus it can be seen that the bamboo-like fiber fabrics have high washing fastness, and at the same time, the fabric prepared in example 5 has high moisture permeability and moisture regain, because a network cross-linked structure is formed between tetramethyldivinyldisiloxane and olefin groups in the antibacterial moisture-absorbing monomer, as shown in fig. 1, and a network skeleton is formed by connecting silicon-oxygen bonds and alkyl groups, and has high hydrophobic property, and branched chains of the antibacterial moisture-absorbing monomer connected to the network structure contain a large number of water-absorbing groups, and because the branched chains are connected through amino groups, the amino groups are in a triangular pyramid structure, wherein the three groups connected are dispersed in three different directions in space, and further, the branched chains of the antibacterial moisture-absorbing monomer and the network structure are not on a uniform plane, the water absorption branched chains extend out of the surface of the net structure, so that the prepared polymer forms a hydrophobic net structure framework, a large number of water absorption groups are uniformly distributed on the surface of the hydrophobic net structure framework, the prepared fabric realizes the effect of quick water absorption and sweat absorption of the branched chains, and the absorbed water can not be completely soaked due to the hydrophobic effect when reaching the net structure framework after being soaked inwards, so that the fabric can be quickly dried, and further the effect of quick sweat absorption and quick drying is realized; the fiber prepared in example 6 does not contain a pore structure on the surface, so that the moisture absorption and moisture removal performance is reduced, meanwhile, only one quaternary phosphonium salt is contained in example 7, only one quaternary ammonium salt is contained in example 8, compared with the case that two quaternary phosphonium salts are contained in example 5, the moisture absorption and moisture removal performance of the fabric is reduced due to the fact that the content of the water absorption group grafted on the surface of the fabric is reduced, the moisture absorption performance of the fabric is slightly reduced due to the fact that no isothiazolinone group is introduced in example 9, the moisture absorption performance of the fabric is greatly reduced due to the fact that salt salts and hydroxyl groups are not contained in example 10, and meanwhile, the moisture removal performance inside the framework is reduced due to the fact that no siloxane bond is introduced into the main chain net-shaped framework in example 11.
According to GB/T5453-1997, the air permeability of the fabrics prepared in examples 5 and 6 is measured by using a fabric air permeability meter, wherein the air permeability of the fabric prepared in example 5 is 2015mm/s, and the air permeability of the fabric prepared in example 6 is 1897mm/s, and the air permeability of the fabric is further improved because the fabric prepared in example 5 contains a large number of pore structures.
The method comprises the steps of measuring fabric which is dried before and after cleaning and bacterial liquid of escherichia coli and staphylococcus aureus by adopting a vibration bottle method according to GB/T20944.3, adding the fabric and the bacterial liquid of the escherichia coli and the staphylococcus aureus into a test flask containing buffer solution, adding only the bacterial liquid of the escherichia coli and the staphylococcus aureus into a control flask without adding the fabric, vibrating the test flask and the control flask at 25 ℃ for 1 hour, 8 hours and 24 hours, measuring the antibacterial rate P of the fabric when vibrating for different time, and specifically measuring the results shown in Table 2; wherein, P is (W-Q)/W is multiplied by 100 percent, and W is the viable bacteria concentration (CFU/mL) in the test flask after shaking for a certain time; q is the viable bacteria concentration (CFU/mL) in the control flask after shaking for a certain time;

As can be seen from table 2, the fabrics prepared in examples 5 and 11 have high antibacterial performance and high antibacterial efficiency, and can achieve high antibacterial effect after shaking for 1 hour, because the antibacterial moisture-absorbing monomers used in the preparation process of the bamboo-like fiber contain two quaternary phosphonium salt groups and one isothiazolinone group, the quaternary phosphonium salt can adsorb negatively charged microorganisms due to positive charge, and the antibacterial effect is achieved, because the radius of phosphorus atoms in the quaternary phosphonium salt is larger than that of nitrogen atoms in the quaternary ammonium salt, and the polarization effect is stronger, the quaternary phosphonium salt is easier to adsorb microorganisms than the quaternary ammonium salt, because the prepared monomers contain two quaternary phosphonium salt groups, the adsorption on microorganisms is further improved, the adsorption with cell membranes of the microorganisms can be better, the contact death caused by the respiratory function of the microorganisms is inhibited, and simultaneously because the content of the quaternary phosphonium salt groups is increased, the quantity of positive charges is improved, after bacteria are adsorbed, the surface charge quantity of the bacteria is changed to a large extent to generate bacterial dissolution, high-efficiency sterilization performance is realized, meanwhile, after quaternary phosphonium salt adsorbs microbial cell membranes, isothiazolinone groups directly destroy DNA molecules in bacterial cells to make the bacteria lose activity, the quaternary phosphonium salt is used for bacterial adsorption and destroys external cell walls of the bacteria while adsorbing, the isothiazolinone groups simultaneously destroy the adsorbed DNA molecules in the bacteria, and high-efficiency and quick sterilization effects are realized through the cooperation of the quaternary phosphonium salt and the isothiazolinone groups; in example 6, the content of the antibacterial contact sites of the fiber is reduced due to the fact that the fiber does not contain a pore structure, so that the antibacterial efficiency is reduced, in example 7, the adsorption effect of the fiber on bacteria is reduced due to the reduction of the content of phosphine chloride, in addition, the change of the environment on the surface of the bacteria is reduced, so that the antibacterial efficiency is reduced, in addition, the adsorption effect of the quaternary ammonium salt used in example 8 on the bacteria is lower than that of quaternary phosphonium salt, so the antibacterial performance of example 8 is lower than that of example 7, in addition, no isothiazolinone group is introduced in example 9, so that the antibacterial effect is only the adsorption damage on cell membranes, and the effect on the inside of bacterial cells is not caused, so the antibacterial effect is reduced, in addition, in example 10, only the isothiazolinone group is contained, and the positive ion is not contained, so that the adsorption performance on the bacteria is reduced, and the direct contact with the bacteria is, the efficient sterilization effect on the interior of bacteria can not be realized under the condition of no contact, so the sterilization efficiency is low, and meanwhile, in example 12, due to the fact that the quaternary phosphonium salt is directly added, the content of the quaternary phosphonium salt on the surface of the fabric is uneven, and the antibacterial performance of the fabric is reduced.
After the fabrics prepared in example 5 and example 12 were respectively washed 50 times, the antibacterial performance of the fabrics in example 5 and example 12 at 1h and 24h was measured according to the above method, wherein the fabric prepared in example 5 had an antibacterial rate of 95.2% against escherichia coli at 1h, an antibacterial rate of 98.3% against staphylococcus aureus at 24h, an antibacterial rate of 99.8% against escherichia coli at 24h, and an antibacterial rate of 99.9% against staphylococcus aureus, and thus it was found that the antibacterial performance of the fabric prepared in example 5 did not change much after repeated washing, whereas the fabric prepared in example 12 had an antibacterial rate of 76.3% against escherichia coli at 1h, an antibacterial rate of 79.2% against staphylococcus aureus at 24h, an antibacterial rate of 95.9% against escherichia coli at 24h, and an antibacterial rate of 97.8% against staphylococcus aureus after washing, the antibacterial efficiency of the fabric prepared in example 12 is reduced after the fabric is washed for a plurality of times, and since the quaternary phosphonium salt is directly loaded on the fabric through the dipping action, the content of the quaternary phosphonium salt on the fabric is reduced after the fabric is washed for a plurality of times, so that the antibacterial performance of the fabric is reduced.
