The decorator’s fabric decision: how 100% cotton, CVC and tri-blend each behave under screen printing and DTG, the vintage-soft-print effect tri-blends give, durability and cost trade-offs, and which base to choose per job.
What a final inspection actually checks before your garments ship: quantity and assortment, AQL workmanship sampling, measurements, labels and compliance, packing, the complete checklist, who should inspect, and what to do when a lot fails.
How garment sizing really works between brand and factory: the base-size spec, grade rules, points of measure and tolerances, what to send, what happens if you send nothing, and the sizing traps (unisex, UK vs US, kids’ heights) that cause returns.
The three fabric families uniform buyers choose between, cotton-rich CVC, poly-rich TC, and full polyester, compared on comfort, industrial washing, embroidery, colour life and cost, with plain guidance by role and industry.
Why cotton knits shrink (spinning and knitting tension, not magic), how much shrinkage is normal, what compacting does at the mill, the tolerance to put in your tech pack, and how to wash-test a sample before approving bulk.
The three knit constructions behind almost every tee and polo: how each is made, what it does to weight, stretch, print quality and cost, the curling-and-twisting quirks factories manage, and which construction fits which product.
Combing is the fibre-preparation step that separates premium tees from budget ones: what it removes, why combed cotton prints sharper and pills less, how it pairs with ring spinning, and when carded cotton is honestly good enough.
The single yarn choice behind why two “100% cotton” t-shirts feel completely different: how ring-spun and open-end cotton are made, what each does to softness, printing, pilling and price, and which to specify for your programme.
What hoodie GSM actually means, the weight bands (250–300 everyday, 300–350 standard, 350–450 heavyweight, 450+ ultra), how much hoodies weigh in grams, brushed vs loopback at each weight, and which GSM to order for your market.
Terry and fleece start life on the same knitting machine — the difference is what happens at finishing, and it changes warmth, breathability, print behaviour, and durability. Constructions (why 3-thread fleece is the premium marker), GSM bands, blends, dye methods, and what decorators should spec.
Everyone thinks they know polos — which is exactly why they get under-specified. The fabric choice is really a decoration choice, the collar is where quality is judged in one second, and the failures (curl, twist, fade) are all preventable at spec stage. A buyer’s guide for uniform and promo programmes.
Bulk production copies your sample — including its mistakes. Why buyers approve samples too fast (excitement, deadlines, sunk cost), and the disciplined checklist that catches problems while they still cost nothing: measure against spec, wash before approving, check the inside, archive the standard.
How garment quality control and AQL inspection actually work — defect classes, inspection stages, a copy-and-use QC checklist, and how to inspect an order before it ships.
