6-Stage Quality Control: How We Ensure Every Pair Meets International Standards

Before a single sock is knitted, we inspect all incoming yarn for count, twist, strength, color fastness, and composition. We test cotton content, verify OEKO-TEX compliance, and reject any batch that doesn't meet our specifications. This single step prevents 60% of potential quality issues downstream.

QC inspectors patrol the knitting floor every 2 hours, checking needle breaks, pattern accuracy, size consistency, and fabric weight. Each machine operator also performs self-checks every 30 minutes. Any defective sock is removed immediately—the machine is adjusted before continuing production.

The linking (toe-closing) stage is where many defects appear—seam thickness, skipped stitches, or misaligned seams. We inspect every sock at this point, rejecting any with visible seam issues. For premium brands, we also perform a "wear test" on random samples to ensure seam comfort.

After boarding (heat-setting on metal forms), we check each sock for correct size, shape, and surface finish. Socks that are stretched, wrinkled, or don't match the foot form are pulled. This is also where we verify color consistency across the production batch.

We perform AQL 2.5 random sampling on finished goods, checking dimensions, weight, color, labeling, and packaging. This statistical method ensures that with 95% confidence, the entire batch meets quality standards. Any batch that fails is 100% inspected.

Before goods leave the factory, we perform a final check: correct quantities, proper packaging, carton markings, and shipping documentation. We also take photos of the container loading process and share them with the client as proof of shipment condition.
