Knitwear & Sweater Inspection from 1688 for Fall/Winter Importers | $169

Why Knitwear QC Is Different From Woven Garment QC

Knitwear stretches, pills, shrinks, and loses shape differently than woven fabric. A sweater that looks perfect on a hanger can stretch out at the neckline after two wears, pill under the arms after a week, or shrink a full size after the first cold wash. For US and EU importers sourcing from 1688, these defects cause 20-35% return rates in the ecommerce knitwear category. Pre-shipment inspection prevents this.

What Are the Critical Knitwear QC Checks?

1. Yarn Quality & Composition Verification

Inspector pulls yarn samples and verifies fiber content against the 1688 supplier's spec sheet. Burn test for cotton vs acrylic vs wool blends. GSM measurement on a 10cm x 10cm cut sample. Common 1688 issue: "wool blend" sweaters that contain <20% actual wool.

2. Gauge & Stitch Density Consistency

Stitch count per 10cm measured across the front panel, back panel, and both sleeves. Acceptable tolerance: ±3 stitches per 10cm. Inconsistent gauge causes visible patchiness after the first wash — a top return reason on Amazon and Zalando.

3. Pilling Resistance (Martindale Test)

Fabric samples undergo 2,000 cycles on the Martindale abrasion tester (ISO 12945-2). Pilling grade < 3 means the sweater will fuzz visibly within weeks. Most 1688 knitwear tested at grade 2-3 — acceptable for fast fashion but borderline for premium brands.

4. Shape Retention & Dimensional Stability

Mark 50cm x 50cm on the fabric, run through 3 wash cycles at 30°C, air dry flat. Measure again. Shrinkage (warp + weft) must stay within 5%. Neckline and ribbed cuffs must not stretch out more than 8% after wear simulation.

5. Loose Thread & Fly Yarn Control

Each sweater inspected inside-out for loose threads longer than 2cm, untucked floats, and laddering at armhole and side seams. Acceptable threshold: maximum 3 loose threads per garment, none visible on the outside.

Step 1: Match Yarn Samples to Production Fabric

When your 1688 supplier ships a sweater sample, CloudSpects can hold the swatch for comparison against bulk production. Inspectors verify hand feel, thickness, and composition before any AQL check begins.

Step 2: AQL Sampling at the 1688 Factory

For knitwear, use AQL 1.0 (strict) for major defects like holes, dropped stitches, and incorrect sizing. AQL 2.5 (normal) for minor defects like loose threads and slightly uneven stitching. Sample size per ISO 2859-1.

Step 3: Pre-Shipment Inspection & Container Loading

After pilling, shrinkage, and gauge checks pass, your approved sweaters are sealed into poly bags, packed into cartons, and container loaded with CloudSpects supervision. Carton drop weight verified per packing list.

Frequently Asked Questions

Can you test knitwear for EU flammability standards?

Yes — if your sweaters are classified as children's sleepwear or high-risk garments, we coordinate EN 14878 flammability testing at our lab partner. Standard inspection begins at $169/man-day.

How do I avoid pilling on 1688 sweaters?

Ask your 1688 supplier for yarn twist count (higher twist = less pilling) and fiber length (longer staple fibers pill less). CloudSpects includes yarn twist verification in the standard knitwear inspection checklist.

Do you check sweater sizing against size charts?

Yes — each sampled sweater is laid flat and measured across chest, length, sleeve length, and shoulder width. Compared against the 1688 supplier's size chart. Tolerance: ±1cm for chest, ±0.5cm for length.
