Capillary Wicking Structure for Running Tees: Development Timeline

From first enquiry to repeat bulk, this is the typical path for short sleeve running tees built with Capillary Wicking Structure. The steps matter more than the calendar, because skipping one is how odour claims fail later.

Week one: brief and fabric choice

We agree the sweat zone, the use case of road, trail and treadmill running and the target of moisture management class above 4 with one-way transport index above 300. Fabric is proposed at lightweight single jersey and 110-150 GSM with Capillary Wicking Structure as the odour-control route. The sweat zone for short sleeve running tees is the underarm and the lower back panel, which is where the treatment has to sit.

Week two to three: laboratory validation

Laboratory knits are produced and tested to AATCC 195 moisture management. If the result is short, add-on level or yarn type is adjusted before any garment is cut. Every lot is measured against AATCC 195 moisture management before the fabric is released for cutting.

Week four to five: wear trial

Samples are worn for road, trail and treadmill running and assessed at the underarm and the lower back panel by a small panel. Laboratory data predicts performance, but wear trials find the problems customers would report. Cost impact is a small yarn and knitting premium, usually under five cents, which is usually recovered through fewer returns across a season.

Week six to seven: pre-production

The recipe is fixed, wash durability is confirmed at permanent, because it is construction rather than chemistry, and care wording is written as avoid fabric softener, which blocks the capillaries. Colour and hand are approved against the same standard as the untreated base fabric. Wear trials were run under road, trail and treadmill running rather than in the laboratory alone.

Bulk and repeats

Bulk ships with a test report per lot. Because the recipe is documented, the second order behaves like the first, which is the part most odour-control programmes get wrong. The care label states avoid fabric softener, which blocks the capillaries, and that wording is the condition behind permanent, because it is construction rather than chemistry.
