Antibacterial Finish Frequently Asked Questions
Short answers to the questions buyers ask most often about Antibacterial Finish.
What does it mean?
chemistry reducing bacterial growth. Working figures for Antibacterial Finish normally sit around 99% reduction target in mainstream production. Note ISO 20743 or AATCC 100 on the tech pack so nobody tests against an older revision.
What value should be specified?
Start from 99% reduction target and adjust for the end use of the garment. Record elastane content alongside Antibacterial Finish, because blends shift the measured value. A result outside 99% reduction target usually points to process drift rather than to the fibre itself.
How is it tested?
ISO 20743 or AATCC 100. Keeping reference values for Antibacterial Finish lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 20743 or AATCC 100, since both affect the reading.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. Working figures for Antibacterial Finish normally sit around 99% reduction target in mainstream production. Note ISO 20743 or AATCC 100 on the tech pack so nobody tests against an older revision.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. Record elastane content alongside Antibacterial Finish, because blends shift the measured value. A result outside 99% reduction target usually points to process drift rather than to the fibre itself.
