Antibacterial Finish Setting It Correctly on a Tech Pack
Antibacterial Finish should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
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.
Target value
Open the specification at 99% reduction target, adjusted to the end use. 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.
Method line
Always pair the target with ISO 20743 or AATCC 100 so the mill and the laboratory test the same way. 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.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. 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.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. 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.
