AATCC30 is to calculate the antifungal and rot-resistant properties of textile material.
The properties of the textile material against fungal and decay resistance were determined to evaluate the effectiveness of the fungicide on the textile materials’ antibacterial property. It divided into soil buried method, agar plate method and humidity bottle method etc.
Soil burial test refers to bury the sample (with a certain size) in the mud for a certain time, determined the sample breaking strength. This method is to use the losing tensile strength of buried sample to characterize its anti-mildew ability.
Agar plate method is used to evaluate the fabric ability of resistance to these bacteria. This method is to evenly drop on a certain amount of aqueous dispersion with aspergillus fumigatus spores on agar plate containing amino acids, then put the non-ionic wetting agent processing wafer sample on it, and drop a certain amount of the aqueous solution on it, placed it in a certain temperature for a period of time, then observe the mold growth information on the sample. It is to use the mold area on the sample for characterization.
Humidity bottle method is to hang the after pretreatment sample on a wild-mouth bottle, which is ventilated, with a certain bacterial spores in the aqueous solution, placed in a certain temperature for a period of time. This method is also to use the mold area on the sample for characterization.
