Upon the client's arrival, the design department and pattern-making team guide them through the technical preparation phase. Our senior pattern maker demonstrates the comparison between the "design sketch" and the "precision paper pattern" converted by the factory. The paper patterns are made of thick kraft paper, with laser-cut edges to ensure zero deviation, and marked with notches, alignment points, and seam allowance parameters at key areas. The pattern maker uses a caliper to measure seam tolerances and provides detailed explanations, while the client randomly verifies three sets of pattern data using an electronic distance measuring device, confirming that the deviation is controlled within ±0.05 cm.
*Cutting Process and Material Control
Before entering the cutting workshop, the client reviews the fabric inspection report to verify that the fabric's weight, color fastness, shrinkage rate, and other indicators meet the contract requirements. In the workshop, senior cutting technicians operate automated cutting machines, using laser alignment technology to ensure neat stacking of the fabric. The blade temperature is maintained at a constant 85°C to ensure clean and precise cutting, avoiding scorching. The client randomly inspects the cut fabric pieces using a magnifying glass to confirm that there are no frayed edges or delamination. The technician adds: "Each batch of fabric undergoes backlighting inspection to eliminate weaving defects. If yarn knots or color differences are found, the entire roll of fabric will be isolated and returned."
*Sewing Process and Craftsmanship Standards
The sewing workshop is divided into process areas. The client focuses on high-precision operations:
1. **Neckline and Armhole Sewing Station**: Skilled operators use computer-controlled flat sewing machines to ensure uniform stitching and consistent tension. After sewing, quality inspectors use a metal probe to test the seam strength, requiring a tensile strength of ≥25N.
2. **Buttonhole Processing**: The CNC buttonhole machine has seven preset sewing modes. Workers fix the garment on a mold positioning plate to maintain a buttonhole spacing tolerance of ≤0.3 mm. The client randomly inspects 10 garments to confirm that the buttonholes are smoothly cut, without frayed edges or missed stitches. The workshop supervisor emphasized: “All sewing machines are calibrated twice daily, and needles are replaced every four hours to prevent fabric damage caused by needle wear.”
*Batch Inspection and Traceability
The final inspection area is equipped with LED shadowless lamps and fabric inspection machines. The quality team conducts 100% comprehensive inspection in four stages:
1. Preliminary Inspection: Collars and cuffs are folded to their extreme angles to test lining adhesion and seam strength.
2. Size Measurement: An electronic ruler scans 32 key points on the garment and compares them to the tolerance table provided by the customer (e.g., length tolerance of ±0.5 cm).
3. Detail Inspection: A magnifying glass is used to check for hidden threads on buttons and skipped stitches in inner seams.
4. Functional Testing: 3% of the products are sampled and subjected to three washing cycles to verify dimensional stability and colorfastness.
Non-conforming garments are tagged with a red label, triggering an automated traceability system linked to the batch, workstation, and operator ID.
*Packaging and Logistics Protection
The packaging workshop implements a layered protection scheme:
1. Pre-treatment: Garments are steam ironed and hung for 20 minutes to remove moisture.
2. Inner Packaging: Custom-made PE dustproof bags with corrugated cardboard shoulder supports maintain the garment's shape and are separated by moisture-proof paper.
3. External Reinforcement: Double-layered corrugated cardboard boxes are lined with bubble wrap and include a humidity/temperature recording card. Boxes are labeled with "This Side Up" and center of gravity warnings, and sealing tape has an adhesive strength of ≥40N/cm².
This end-to-end workflow—standardized operations, data-driven monitoring, and expert judgment—ensures quality control at every stage from design to delivery, reflecting our factory's strict commitment to excellence.
