B – During Production Inspection
During Production inspection (DUPRO) involves continuous monitoring of textile products during various stages of manufacturing. This type of inspection is crucial for detecting defects early and preventing them from escalating into more significant problems. Key checkpoints in in-process inspection include weaving, dyeing, printing, and finishing.
Techniques used in DUPRO range from visual checks by trained personnel to advanced automated systems. For instance, during weaving, inspectors may look for issues like broken threads or incorrect patterns. In dyeing and printing, color consistency and pattern alignment are critical factors that inspectors monitor. Automated inspection systems, equipped with cameras and sensors, can quickly identify defects and alert operators, ensuring timely corrections.
C – Pre-Shipment Inspection
Pre-shipment inspection (PSI) is the last step before textile products are packaged and shipped to customers. This comprehensive inspection ensures that finished goods meet all specified quality criteria, such as size, color, construction, and overall appearance.
There are two main methods used in PSI inspection: Acceptable Quality Level (AQL) sampling and 100% inspection. AQL sampling involves inspecting a random sample of the finished products based on predetermined standards. If the sample passes the inspection, the entire batch is accepted. Conversely, 100% inspection means examining each item in the batch to ensure it meets quality standards. While more time-consuming, 100% inspection is often used for high-value or critical products where defects are unacceptable.
Textile Product Inspection Techniques and Tools
