Ultra-Fresh treated disposable curtains will contain the antibacterial treatment until the end of their useful life and until recycled. The active antibacterial additive will be present at low concentrations at the point of recycling. If, for example, the disposable curtains fabric is re-melted and mixed with other post consumer waste of a similar type, the active antibacterial will be diluted but still remain in the resultant blend. The antibacterial efficacy will diminish as the additive is diluted during the recycling process.
