Compression Decay Solutions for Yoga Sets: Sourcing Checklist for Buyers
Questions to put to any mill supplying coordinated yoga sets with compression decay specified.
Capability questions
Ask for the test equipment list and the standards used. The relevant method here is ISO 13934-1 tensile with cyclic extension, and the mill should be able to show recent reports. 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.
Documentation
Request the technical data sheet, composition certificate and previous results for above 90% elastic recovery after 20000 cycles. Consistent paperwork usually reflects consistent process control. Keep ISO 13934-1 tensile with cyclic extension named in the tech pack so every lot is measured the same way.
Mill visit checks
Look at finishing conditions and testing frequency. Problems such as the garment loses its support value over the wearing life often come from process drift rather than design. Where coordinated yoga sets is worn for studio practice and everyday wear, set tolerances around that range of movement.
Commercial terms
Confirm minimum quantity, lead time and the cost impact noted as higher specification elastane adds 10-15 cents per garment before development work starts. Any change to soft brushed jersey with 4-way stretch requires re-testing against above 90% elastic recovery after 20000 cycles before bulk is released.
Warning signs
Be careful where samples perform differently from bulk, or where reports are only issued on request. Past reports from ISO 13934-1 tensile with cyclic extension help the mill reproduce the same recipe on the next order.
