[0053] To investigate the effect of the component ratio of finishing agents on antibacterial and UV-resistant polyester fiber fabrics, an experiment was designed according to Table 1:

[0054] Table 1. Finishing Agent Component Design Table

[0055]

[0056] The finishing agent AF provided in Table 1 was applied sequentially to the preparation process of antibacterial and UV-resistant polyester fiber fabric to obtain fabric AF. The fabric obtained without finishing agent treatment was used as a control group. The antibacterial and UV-resistant polyester fiber fabrics prepared according to the preparation methods provided in Examples 1-3 above were subjected to antibacterial and UV-resistant tests.

[0057] The antibacterial test method was based on GB / T 20944.2-2007 "Evaluation of Antibacterial Properties of Textiles" Part 2: Absorption Method. The test strains were Staphylococcus aureus ATCC No. 6538 (Gram-positive bacteria), Escherichia coli 8099 (Gram-negative bacteria), and Candida albicans ATCC No. 10231 (Candida spp.). According to the standard, fabric AF and the fabrics provided in Examples 1-3 and the control group were cut into 20mm×20mm pieces. After 50 washes, the antibacterial test was conducted. The results are shown in Table 2.

[0058] The UV resistance test was conducted according to GB / T17032-1997, which determines the UV transmittance of textile fabrics. According to the standard, fabric AF and the fabrics provided in Examples 1-3 and the control group were cut into 20mm×20mm sizes to ensure that the sample fabrics were dry and not twisted. The test wavelength interval was 5nm, and the UVR wavelength range was 280-315nm. Each sample was tested 5 times, and the average UV shielding rate was calculated. The results are shown in Table 2.

[0059] Table 2 Statistical Table of Results

[0060]

[0061] As shown in Table 2, the fabric treated with finishing agents has stronger antibacterial and UV resistance than the fabric without finishing agents. When finishing agent C is used, the resulting fabric C has an advantage in antibacterial effect against Staphylococcus aureus, Escherichia coli, and Candida albicans, and has better antibacterial properties. In addition, the UV shielding rate of fabric C is also higher than that of other groups.

[0062] Subsequently, for fabric AF, the fabric obtained without finishing agent treatment was used as a control group, and the antibacterial and UV-resistant polyester fiber fabric prepared according to the preparation methods provided in Examples 1-3 above was subjected to performance tests for smoothness, anti-pilling, and anti-bubbling.

[0063] The results showed that the fabric treated with finishing agents had better smoothness and a smoother hand feel than the fabric without finishing agents. In addition, the fabric was better than the control group in the tests of anti-pilling and anti-fuzzing. There were also differences between the fabrics using different ratios of finishing agents. Fabric C had better anti-pilling and anti-fuzzing effects. After 50 washes, its surface still had good smoothness, and its surface pilling and fuzzing were less than other groups.
