In the garment manufacturing, maintaining high-quality standards is crucial for meeting buyer expectations and reducing defects. Sewing quality control plays a vital role in ensuring that every piece produced aligns with industry standards. A well-defined Standard Operating Procedure (SOP) helps streamline inspection processes, minimize errors, and improve overall efficiency on the production floor.
Now we will outline a step-by-step SOP for sewing quality control, covering key areas such as defect prevention, measurement accuracy, bundle management, and compliance with buyer requirements. Whether you're a quality inspector, production manager, or factory owner, this guide will help you enhance your quality control processes for better productivity and customer satisfaction.
Initial Quality Inspection
ü Inspectors must review the sample and trim card at the start of each new style.
ü Special attention should be given to SPI (stitches per inch), thread, labels, and the first bundle.
ü The Quality Inspector (QI) must take over the inspection process from the Quality Controller when a new style begins.
Measurement and Checkpoints
ü Inspectors must be familiar with all measurement checkpoints and be able to explain them clearly when asked.
ü No defective garments should pass through the QI checkpoint. If a defect is found, it should be limited to a single bundle per process.
Bundle Management
ü Bundles must be maintained as per the cutting report.
ü Short or incorrect bundles should not be allowed to pass through the QC checkpoint.
Inspection Standards
ü Each QI must have a measuring tape readily available at all times.
ü In-process reports must be updated hourly and signed by both the QC and line supervisor.
ü Any process or size-related errors must be corrected before proceeding further in production.
Line Display and Organization
ü The sample and trim card for each running style must be displayed clearly on the production line.
ü Inspectors should ensure that machines are cleaned before the end of each shift.
ü Every machine must have an oil card to track lubrication.
Washed Garments Handling
ü Washed garments should not be kept in the sewing line.
ü If any washed garments are found in the sewing section, the Output QI and Line QC must ensure they are handed over to the finishing department.
Buyer Compliance Responsibility
ü Each Line QC is responsible for ensuring that all buyer requirements are met within their respective lines.
By following these SOPs, the sewing quality control process can be maintained effectively, ensuring high standards and reducing defects.
