The formulations of the filaments used in examples 1 to 5 and comparative example 1 were as follows, the components being in weight percent:
| antibacterial agent (%) | PP(％) | PE(％) | EVA(％) | |
| Example 1 | 5 | 80 | 5 | 10 |
| Example 2 | 5 | 80 | 8 | 7 |
| Example 3 | 5 | 80 | 10 | 5 |
| Example 4 | 5 | 50 | 20 | 25 |
