Fabric & Materials for Apparel Development

AQL in garment inspection is the defect rate accepted in a random sample. Learn how sampling works, defect levels, and when 100% final inspection is used.

Compare proto and pre-production samples: what each verifies, how fabric, trims and workmanship differ, and where fit and size-set samples fit in.

Follow the development steps: set support level, choose fabric, define cups and padding, then sample, wear-test and grade sizes before bulk production.

Low, medium and high impact sports bras compared by activity, compression vs encapsulation, straps, underband and fit, plus how brands plan each level.

How recycled polyester compares with virgin polyester for activewear on performance, cost and sustainability — and what to verify before ordering.

The best fabric for sports bras depends on impact: nylon-spandex or polyester-spandex for support and recovery, cotton blends for low-impact comfort.

Most leggings fall in the 200–260 GSM range: yoga around 240–280, gym 220–280, compression 260–300. Test opacity on stretched fabric, not the roll.

Nylon vs polyester for activewear: nylon-spandex is softer with better stretch recovery; polyester-spandex manages moisture and holds prints. Compare both.

Raglan sleeve vs set-in sleeve: where each seam runs, and how they compare on fit, movement, shoulder look and decoration in tees and hoodies.
