The acrylic acid layer 4 and a sulfuric acid and hydrogen peroxide having a volume ratio of 1: 9 are subjected to a peroxy acidification process at 0 ° C for 1 reaction. 0.5 ~ 6 hours' formation-peroxyacid layer 5 and after the reaction, the surface of the remaining peroxyacid layer 5 is washed with ice methanol Sulfuric acid and nitrogen peroxide. Isopropylpropanamine (0_1M acetic acid as a solvent) and the peroxyacid layer 5 were irradiated with 10 ~ 50 minutes first to obtain an isopropylpropionamine Thin layer 6. Polychitinase with 10.1M acetic acid as the solvent and a solution concentration of 5wt%, and added with 1mMwt% pentosan solution, cooled at _196t; 24 hours in the east, and then dried 2 times Process 'The polychitosan is grafted and fixed on the isopropyl propylene amine layer 6 to form a polychitosan layer 3. A month, see Tables 1 to 3', this is a polychitin containing this creation Test table for water absorption time and temperature sensitivity of sugar materials, bactericidal test result table for the poly 12 M274953 alpha / Λ sugar-containing dressing of this creation, and water vapor transmission test table for the poly-chitinase-containing dressing of this creation . As shown in Table 1, it can be seen that as the content of acrylic acid decreases, the content of isopropylacrylamide increases and its relative water absorption time increases, and the polyacrylase is grafted onto acrylic acid and isopropylacrylamide layer 2 After that, its water absorption time was relatively reduced, showing its increased hydrophilicity. According to the table, AN11 'Non-woven fabric was grafted with isopropyl propylene, and the hydrophilicity was lower at 41 and 53 ° C. It can be seen that the non-woven fabric was fixed and grafted. After having temperature sensitivity. In addition, as shown in Table 2, it can be seen that the non-woven fabric containing acrylic acid, isopropylpropylamine, and polychitinase has better reeling after being treated with light, and shot. As shown in the value of Table 2, the non-woven fabric It will not kill g, but will promote the growth of fine g. * When the non-woven fabric contains acrylic, it has a "killing effect" after isopropylacrylamide, which can reduce the number of bacteria! ... After the acrylic acid and isopropyl propylamine amines were found on the cloth, the number of bacteria was further reduced by a large amount, showing that the bactericidal effect was increased. As shown in Table 3, it can be seen that as the content of acrylic acid decreases, the The increase in the content of propyl propylamine, its water vapor transmission rate, permeability, and air permeability all show a downward trend. This is because acrylic acid is more water absorbing than isopropyl propylamine. When the amount is reduced, it also reduces its hydrophilicity and water vapor permeability. After the chitosan is grafted and fixed on the acrylic and isopropylacrylamide layer 2, its structure is tighter due to its thicker film and larger cross, which hinders it. Water vapor transmission 'so water vapor transmission rate, permeability' The air permeability shows a downward trend. Please refer to [Tables 4 to 7], which are the relative water absorption schedules of the chitosan-containing dressing M274953 and the temperature-sensitive properties of the polygadolin-containing dressing. Table K, another-the sterilization test result of the dressing containing polycarp shell crepe, the water vapor transmission test table of the dressing with polycarp shell sugar, ^ This table shows that 7F ' After propylacrylamide is grafted and solidified, its water absorption time is reduced, showing an increase in its hydrophilicity. In the case of polychitin vinegar, its water absorption time is significantly reduced, indicating that its hydrophilicity has been further increased-due to the polychitinase It is very hydrophilic and can absorb a large number of waterjets quickly, so the hydrophilic properties of nonwovens can be greatly increased after the combination of chitosan. In addition, the comparison of non-woven fabrics containing chitosan made by different temperatures; , Poly-F㈣-containing dressings made at -196Ϊ, have a higher water absorption time. As shown in Figures 4A to 5B, we can see that poly-chitosan-containing dressings made in the _19th generation Its structure is denser, its dense knot It will make water harder to get into the dressing containing polyenzyme. As shown in Table 5, it can be seen that at 15, MCN · Isopropylacrylamide layer 6 has a water absorption time ratio of 38, C .. It is shown that its hydrophilicity is better at 15, 25 C, and its poor hydrophilicity at 38 and 53 c also shows that the isopropyl propylamine layer 6 is temperature sensitive and reaches the utilization temperature The purpose of changing its hydrophilicity is shown in Figure 2. As shown in II.6, it can be seen that the non-woven fabric itself has no bactericidal effect, but it will promote the growth of bacteria. After containing the isopropylpropylamine layer 6, its bactericidal effect is slightly Increased. After the chitosan is grafted and fixed, the chitosan itself has a bactericidal effect to further increase the bactericidal effect. As shown in Table 7, it can be seen that the isopropylacrylamide layer 6 Later, its water vapor transmission rate, permeability, and air permeability all showed a downward trend, which was caused by the isopropylpropylamine layer 6 forming a uniform dense layer that prevented water vapor transmission. Connected via polychitosan 14 M274953 = solid, because chitosan has greater hydrophilicity, its water vapor transmission rate, tooth permeability, and air permeability are all increasing. On the other hand, a dressing made of chitosan containing polycaproxene can be found in the chitosan-containing dressing made at ⑽c,… 8 ”where = 12 = the fine barrier properties of non-woven non-woven fabrics test. As shown in the table, the dressings of crustacean are fixed and grafted, and the amines are made: The non-woven fabric of diisopropylpropylamine layer 6 is made of bacteria = after the propyl group, no bacteria pass through the non-woven fabric containing isopropyl For the details of the trapping, please refer to the figure shown in "Figure 7"-it means that the mouth of the dressing containing poly-shell is not as good as liquid, such as the solubility of 3 metal ions on Aq, Δ, π Έ. As shown in the figure, taking AN3 = Natural Shade Drying, as an example to increase the dressing of the antibacterial polymethan ~ Mqian A9NO3 solution, for example, there is a blank, white-free around the dressing containing :: jiezhi dressing. Antibacterial effect. From the secret of X-NTJ containing silver ions, it can be seen that the non-woven fabric has the best sterilization effect. However, the above is only used by the original to limit the creation of this example.
