[0089] The composite fabrics obtained by weaving in Examples 1-5 and Comparative Examples 1-2 are subjected to corresponding tests, and the test results are shown as follows:

[0090] (1) antibacterial performance test: the composite fabrics in Examples 1-5 and Comparative Examples 1-2 are subjected to antibacterial performance tests according to the test standard GB / T20944.3-2008 Evaluation of antibacterial properties of textiles Part 3: shaking method, and the test results are shown in Table 1:

[0091] Table 1

[0092]

[0093] As shown in Table 1, the composite fabrics in Examples 1-5 exhibit excellent antibacterial effects against Escherichia coli and Staphylococcus aureus. The small size of the graphene oxide added to the composite fabric allows it to cleave bacterial cell membranes, effectively killing bacteria and demonstrating excellent antibacterial properties. Modification of the graphene oxide by introducing long alkyl chains and quaternary ammonium salts on its surface effectively prevents graphene oxide aggregation, allowing for better dispersion within the cotton fiber matrix and improving dispersibility. The cations on the introduced quaternary ammonium salts can adsorb onto the negatively charged bacterial cell membrane surface, thereby altering the permeability of the bacterial cell wall, causing a charge imbalance in the cell membrane, and effectively killing bacteria. The long alkyl chains on the quaternary ammonium salts... Alkane can also interact hydrophobically with the lipid layer on bacterial cells, causing protein denaturation and enzyme inactivation. It has a good inhibitory effect on the growth of Staphylococcus aureus and Escherichia coli, thus achieving an antibacterial effect. In Example 5, the composite fabric can achieve an inhibition rate of 99.0% against Escherichia coli and 99.1% against Staphylococcus aureus. In Comparative Example 1, pyridine-modified graphene was used instead of quaternary ammonium salt-modified graphene, resulting in a significant reduction in antibacterial performance. In Comparative Example 2, graphene oxide was used instead of quaternary ammonium salt-modified graphene. Not only was no quaternary ammonium salt added, but the graphene oxide was also not modified, resulting in poor dispersion and easy aggregation, which greatly reduced the antibacterial performance.

[0094] (2) Wrinkle resistance test: The wrinkle resistance of the composite fabrics in Examples 1-5 and Comparative Examples 1-2 was tested according to the test standard GB / T3819-1997 "Textiles - Determination of Crease Recovery - Recovery Angle Method". The test results are shown in Table 2.

[0095] Table 2

[0096]

[0097] According to the test results in Table 2, it can be seen that the corresponding composite fabric in Examples 1-5 has excellent wrinkle resistance. The treated cotton fibers are immersed in the modified slurry, realizing the bonding of quaternary ammonium salt modified graphene and cotton fibers. The imine groups on the quaternary ammonium salt modified graphene and the hydroxyl groups on the cotton fibers can be effectively combined, realizing the modification of the cotton fibers. The superfine denier polyester fibers are not easy to damage, and have high elasticity characteristics, good wrinkle resistance, and are not easy to deform. The cotton fibers have excellent elasticity. The hydroxyl groups on the superfine denier polyester fibers and the amino groups on the modified cotton fibers can form hydrogen bonds, and the interaction between them is stronger. After weaving, the wrinkle resistance and comfort are improved. The folding recovery angle of the composite fabric in Example 5 can reach 300°. In Comparative Example 2, the graphene oxide is not modified, and the dispersion effect is poor, which is easy to agglomerate, and has a great influence on the performance of the composite fabric, and the wrinkle resistance is greatly reduced, and the folding recovery angle is 273°.

[0098] (3) Air permeability test: The composite fabrics in Examples 1-5 and Comparative Examples 1-2 were tested for air permeability according to test standard GB5453-85, and the test results are shown in Table 3:

[0099] Table 3

[0100]

[0101] According to the test results in Table 3, it can be seen that the corresponding composite fabric in Examples 1-5 has excellent air permeability. Cotton fibers and protein fibers have good skin friendliness, air permeability, and moisture conducting function. The air permeability of the obtained composite fabric. In Examples 1-5 and Comparative Example 1, the graphene oxide is modified, which largely avoids the agglomeration of graphene oxide and uniformly disperses in the cotton fibers. The air permeability of the modified cotton fibers obtained is significantly higher than that of the modified cotton fibers added with unmodified graphene oxide.
