Odour Retention Solutions for Running Shorts: Sample to Bulk Timeline
A realistic plan for developing running shorts with odour retention solved, from first sample to repeat bulk.
Stage one: definition
Fix reduction of 99% against Staphylococcus aureus after 10 washes and the construction route. This is where most delays originate, because unclear targets cause repeat sampling. Because high cadence movement plus perspiration at the waistband, target checks are made on a worn sample rather than flat fabric alone.
Stage two: laboratory sample
Request lab dips and a first fabric sample. Confirm against ISO 20743 and AATCC 100 before cutting, then cut 3-5 pieces for fit. Keep ISO 20743 and AATCC 100 named in the tech pack so every lot is measured the same way.
Stage three: wear trial
persistent smell after repeated wear even when the garment is clean appears during use. Run a two-week trial with road, trail and track training participants before approving bulk. Where running shorts is worn for road, trail and track training, set tolerances around that range of movement.
Stage four: pre-production
Produce 30-50 pieces from bulk materials. This exposes process variation that a hand-made sample hides. Any change to lightweight woven or knit body with a knit liner requires re-testing against reduction of 99% against Staphylococcus aureus after 10 washes before bulk is released.
Stage five: repeat orders
Once approved, keep the recipe and report set together so the next order can be released without redevelopment. Past reports from ISO 20743 and AATCC 100 help the mill reproduce the same recipe on the next order.
