Squat-Proof Coverage Solutions for Yoga Sets: Common Failure Causes and Fixes
Below are the failure patterns most often seen when squat-proof coverage affects coordinated yoga sets, with the correction for each.
Failure: hidden until worn
knitted fabric loses opacity when it stretches over the body usually appears after several sessions. Because it develops slowly, it reaches the customer instead of the inspection table. Because long holds put sustained rather than shock load on the fabric, target checks are made on a worn sample rather than flat fabric alone.
Cause one
low course density so the interstices open under tension. Keep AATCC 183 transmission with photography under 60% extension named in the tech pack so every lot is measured the same way.
Cause two
fine filament yarn with poor covering power. Where coordinated yoga sets is worn for studio practice and everyday wear, set tolerances around that range of movement.
Cause three
light shades that transmit light more than dark ones. Any change to soft brushed jersey with 4-way stretch requires re-testing against opacity above 96% at 30% extension before bulk is released.
Correction and prevention
Apply raise course density to 34-40 courses/cm first, then verify against opacity above 96% at 30% extension using AATCC 183 transmission with photography under 60% extension. Lock the corrected settings into the bulk recipe so repeat orders behave identically. Past reports from AATCC 183 transmission with photography under 60% extension help the mill reproduce the same recipe on the next order.
