What was checked
Fabric contact safety, tested against bacteria and fungi.
The report evaluates antimicrobial performance using quantitative textile test methods. In user terms, the test asks a simple question: when microbes are placed on the towel fabric, how much microbial activity remains after the contact period?
Bacteria method
AATCC 100, used for measuring antibacterial activity on textile materials.
Fungi method
ISO 13629-2, used for determining antifungal activity of textile products.
Test organisms
Four organisms were used to stress-test the fabric.
SITRA tested against two bacteria and two fungi, then compared recovered microbial counts from immediate contact time against the required contact time.
Staphylococcus aureusATCC 6538
Enterococcus faecalisMTCC 439
Aspergillus nigerATCC 6275
Candida albicansMTCC 227
Lab conditions
The setup was controlled and measurement-based.
Samples were sterilized, inoculated, neutralized, diluted, plated, incubated, and counted. This matters because the report is based on recovered colony counts, not a visual opinion.
| Test detail | Report value |
|---|---|
| Sample size | 1 g swatches of 4.8 cm diameter for AATCC 100; 0.4 g swatches of 3.8 cm diameter for ISO 13629-2. |
| Sterilization | Autoclave at 121 degrees Celsius for 15 minutes. |
| Media used | Nutrient agar and nutrient broth for bacteria; Sabouraud dextrose with chloramphenicol agar and Sabouraud dextrose broth for fungi. |
| Neutralizer | Dey Engley Neutralizing Broth for bacteria; SCDLP for fungi. |
| Dilution medium | Sterile distilled water. |
| Plating method | Spread plate method. |
| Incubation | Bacteria at 37 degrees Celsius for 24 hours; fungi at 25 degrees Celsius for 5 to 7 days. |
Interpretation
The result is calculated from recovered microbes.
The report defines reduction by comparing microbes recovered immediately after inoculation with microbes recovered after the required contact period.
Bacterial reduction
R = 100 [(C - A) / C]R is percent reduction. C is the bacteria recovered at 0 contact time. A is the bacteria recovered after the desired contact period.
Antifungal value
A = F - GF is the growth value on control fabric. G is the growth value on antifungal-treated samples.
Referenced standards
The report names the protocols used.
- CM QC P55_AATCC-100 test protocol to study antimicrobial property of textile.
- AATCC 100, assessment of antimicrobial activity on textile finishes.
- ISO 13629-2, determination of antifungal activity of textile products.
- CFU means Colony Forming Units, the counted colonies recovered from the sample.
Plate documentation
The report includes plate images before and after contact time.
