Assessment conditions of the antimicrobial and antifungal effect in the agar diffusion test
| Mean value of inhibition zone (mm) | Growth |
Description | Assessment |
|---|---|---|---|
| > 1 |
None |
Inhibition zone exceeding 1 mm, no growth b) |
Good effect |
| 0 | Slight | No inhibition zone, only some restricted colonies, growth nearly totally suppressed d) | Limit of efficacy |
| 0 |
Moderate |
No inhibition zone, compared to the control growth reduced to half e) |
Insufficient effect |
Evaluation of the electrostatic action of the unwashed and washed textile fabric prepared
| Samples | Resistance | Remarks | Recommendation |
|---|---|---|---|
| Without antimicrobial treatment | 1.75×1012 Ω | Higher than minimum compliance value according to the standard | Not applicable for protective textiles |
| Antimicrobial treated and unwashed | 1.17×109 Ω | Good enough for this application as it is twice lower than the minimum compliance value | Could be used for non-washable systems only |
| Antimicrobial treated and after 1st washing cycle | 2.38×109 Ω | On the limits of error with minimum possible | Cannot be used for protective textiles. |
| Antimicrobial treated and after 2nd washing cycle | --- | Much higher than is required | Cannot be used for protective textiles. |
