Quality Control for Custom Textiles — 4-Step Inspection, 98.5% Yield Rate
Galink runs a documented 4-step inspection from incoming materials to AQL pre-shipment checks across towels, blankets, and bags. Each batch leaves the line only after colorfastness, shrinkage, and stitch-strength tests are logged; the 98.5% yield rate covers every order category on a 12-month rolling basis.
What is your quality control process for custom towels and bags?
Galink's textile quality control process is a 4-step inspection — incoming materials, in-line checks, AQL pre-final sampling, and pre-shipment final inspection — applied to every towel, blanket, and bag order at our 5,000 ㎡ Suzhou factory under AQL 2.5 default. Inspections follow AQL 2.5 (general inspection, default; can adjust per buyer contract to AQL 1.0 or 4.0). The 98.5% yield rate (defect-free) we publish is measured against this 4-step gate, not against a single end-of-line check.
- Step 1 — Incoming material inspection: Every fabric roll, yarn lot, and accessory batch is checked against the buyer's spec sheet before cutting.
- Step 2 — In-line inspection: Floor inspectors walk the line at fixed intervals to catch print defects, stitch skips, and color drift mid-run.
- Step 3 — AQL pre-final inspection: Statistical sampling based on lot size; defects classified critical / major / minor.
- Step 4 — Pre-shipment final inspection: Random carton opening, weight check, and packaging review before container loading.
Why buyers trust it: every step is logged, every batch carries a QC reference code, and lab test reports (colorfastness, shrinkage, GSM) are issued on request — see certifications & ESG for the audit chain behind the numbers.
What is your defect rate and how do you measure it?
Galink publishes a 98.5% yield rate (defect-free), measured as the share of finished units passing all 4-step inspection without any critical or major defect, on a 12-month rolling basis across all towel, blanket, and bag orders shipped from the Galink factory floor. The complement — 1.5% defect rate — captures units flagged at any of the four gates (incoming, in-line, AQL, pre-shipment) and excluded from shipment.
| Metric | Value | Measurement window |
|---|---|---|
| Yield rate (defect-free) | 98.5% | 12-month rolling, all towel / blanket / bag orders |
| Defect rate | 1.5% | Same window; critical + major defects, all gates |
| Re-inspection rate after rework | < 0.5% | Of reworked lots that re-enter the gate |
How it's calculated:
- Numerator — units that pass AQL pre-final inspection with zero critical / major findings.
- Denominator — total finished units across all shipped orders in the rolling window.
- Audit trail — every batch has a QC code; buyers can request the per-batch yield sheet.
Why this matters for buyers: the 98.5% yield rate is published, not just claimed, because lot-level data is auditable — see factory capacity & on-time delivery for how yield links to our 96% on-time rate.
How do you inspect incoming materials before production?
Before any cut, fabric rolls are inspected at the incoming gate against the buyer's spec sheet — covering weight (GSM), width, hand feel, color shade versus lab-dip, and visible flaws — to catch defects before they enter production and inflate downstream rework cost and lead time. Materials that fail are segregated; the supplier is informed within 24 hours.
| Incoming check | Method | Pass criterion |
|---|---|---|
| Fabric weight (GSM) | Cut-and-weigh sample, 3 points per roll | Within ±5% of spec |
| Width | Steel tape, 3 points per roll | Within ±1 cm of spec |
| Color shade | Visual + spectrophotometer vs lab-dip | ΔE ≤ 1.5 against approved lab-dip |
| Hand feel | Buyer-approved reference swatch | Match reference on file |
| Visible flaws | Full roll spread on inspection table | No holes, stains, slubs, misweave beyond AQL |
What we reject: any roll that fails GSM, width, or color shade is quarantined and not released to cutting; replacement rolls are re-inspected on arrival.
What happens during in-line and pre-final inspection?
During production, floor inspectors walk the line at fixed intervals to catch defects; at end-of-run, an AQL pre-final inspection statistically samples the lot to classify defects as critical, major, or minor before the batch moves to packing, sealing, and shipping from the factory. In-line catches process drift early; AQL is the formal release gate before final packing.
In-line cadence (per shift)
| Trigger | Action |
|---|---|
| Start of shift | First 5 units pulled and checked |
| Every 30 minutes | Sample 3–5 units per line |
| After every color / style change | Full re-check first 10 units |
AQL pre-final inspection levels (default AQL 2.5; adjustable per contract)
| Defect class | AQL (default) | Examples |
|---|---|---|
| Critical | 0 | Hole, foreign contamination, broken needle left in product |
| Major | 2.5 | Print misregistration > 3 mm, stitch skip > 5 cm, color off-shade |
| Minor | 4.0 | Slight weave unevenness, loose thread, packaging scuff |
What final inspection checks happen before shipment?
Before any container is sealed, Galink runs a pre-shipment final inspection — random carton opening, packed-unit weight check, label and poly-bag review, and a final visual scan against the buyer's approved golden sample — on every shipment leaving the factory floor. This is the last gate before the goods leave the factory.
Pre-shipment checklist
- Random cartons opened and re-counted vs packing list
- Packed-unit weight checked against target (within tolerance)
- Inner poly-bag and outer carton labels verified (style, size, color, quantity)
- Barcode / carton number scan logged against QC code
- Sample stack held against approved golden sample for color and hand-feel
- FOB / CIF / DDP shipping marks applied per buyer instruction
Outcome: a signed pre-shipment inspection report accompanies every order; buyers receive the digital copy with shipment documents.
Which fabric testing standards do you follow?
Galink tests against publicly named industry methods — colorfastness to washing (ISO 105 C06), to light (ISO 105 B02), to rubbing (ISO 105 X12), dimensional change (AATCC 135 / ISO 5077), and GSM by cut-and-weigh — issuing reports per batch. Reports are issued per batch on request.
| Test | Standard | What it measures |
|---|---|---|
| Colorfastness to washing | ISO 105 C06 | Shade change after repeated wash cycles |
| Colorfastness to light | ISO 105 B02 | Fade resistance under artificial light |
| Colorfastness to rubbing (crocking) | ISO 105 X12 | Dye transfer to dry / wet cloth |
| Dimensional change (shrinkage) | AATCC 135 / ISO 5077 | Length / width change after wash |
| Fabric weight (GSM) | Internal cut-and-weigh | Mass per square meter |
| Stitch strength | Internal pull-test | Seam tensile, ≥ buyer-specified value |
Note: these are public industry test methods applied to each batch — distinct from any factory-level management certification. Buyers can request the latest lab report per batch via contact us.
How can buyers request QC reports and lab test data?
Every Galink order ships with a pre-shipment inspection report; lab test reports (colorfastness, shrinkage, GSM, stitch-strength) for the specific batch are issued on written request within 3 working days, free of charge to all buyers, regardless of order size or destination. This is how buyers verify the 98.5% yield rate behind the marketing line.
