Quality assurance

Quality managed at every stage.

A process-driven quality framework for knitwear — from specification review to shipment release. Inspection scope, test program and acceptance levels are agreed with each buyer.

Quality standards reference

The 41 tests and checks behind every order.

The standards commonly applied to knitted garments, grouped by what they protect. Your quality plan selects the methods, editions and limits for each style and destination market.

Fabric & yarn

The base fabric is right before a single panel is cut.

Methods, editions and pass limits are agreed in the buyer-approved quality plan for each style and market. Testing is carried out at accredited third-party laboratories as required by the buyer; inspections are performed or coordinated by GARWEVIA.

Quality

Each checkpoint is performed or coordinated according to the quality plan agreed with you, and reported with measurements, photos and corrective actions.

Final inspection & AQL

Final random inspection, to your plan.

GARWEVIA can perform or coordinate final random inspections according to agreed buyer specifications. Sampling follows recognised frameworks such as ISO 2859-1 and ANSI / ASQ Z1.4.

Acceptance levels are defined by the buyer or the agreed quality plan. No single AQL applies to every buyer.
Lot size
The number of units in the order or shipment being inspected.
Sample size
How many units are drawn, determined by lot size and inspection level.
Inspection level
The sampling level (for example General II) set in the quality plan.
AQL
Acceptance quality limit — the defect level accepted for each class.
Example acceptance levels
Defect classAcceptance level
Critical defects0 — none accepted
Major defectsAQL 2.5
Minor defectsAQL 4.0

Illustrative example only — buyer specifications prevail.

Critical

  • Broken needle or sharp object
  • Safety hazard
  • Hazardous trim
  • Serious regulatory non-compliance

Major

  • Hole
  • Open seam
  • Wrong garment measurement
  • Wrong colour or serious shade variation
  • Missing component
  • Major print defect
  • Incorrect labelling

Minor

  • Loose thread
  • Minor stitch irregularity
  • Minor appearance issue
  • Small cosmetic defect

Fabric inspection

The 4-point fabric inspection system.

Partner factories may use the 4-point system to assess bulk fabric: each defect is scored by length, and points are totalled per 100 square yards to judge each roll.

Typical defects recorded

  • Knitting defect
  • Hole
  • Contamination
  • Dye streak
  • Barre
  • Oil mark
  • Needle line
  • Shade variation
  • Bowing
  • Skew

Pass / fail point thresholds are set by the buyer or the factory standard for each program — there is no single universal limit.

Packaging quality

Packed exactly as specified.

Packing materials

  • Polybag
  • Recycled polybag, where specified
  • Suffocation warning
  • Size sticker
  • Barcode
  • RFID, where required
  • Hangtag
  • Price ticket

Packing method

  • Assortment
  • Ratio packing
  • Solid packing
  • Carton quantity

Carton & shipping

  • Carton marking
  • Net weight
  • Gross weight
  • Carton dimensions
