Next, long-term wearing stability depends entirely on standardized sewing and shaping craftsmanship. Collar and front placket are the core details that judge denim shirt quality. Many low-grade denim shirts suffer from collapsed collars and deformed plackets after repeated washing. Our factory adopts exclusive double-layer interlining bonding technology to solve this problem. We use professional constant temperature and pressure equipment for lamination treatment. This process ensures the collar stays crisp, straight and non-deformable after long-term wearing and repeated cleaning.
In terms of internal sewing details, all side seams and armhole positions adopt precise flat-felled stitching craft. The internal stitching is flat and burr-free to improve overall wearing comfort. We unify the whole-garment seam allowance to a standard 0.6cm to ensure consistent stitching density for every piece. Our sewing team has an average working experience of more than 5 years, which guarantees stable and precise manual operation. After production, every batch will complete professional shrinkage pre-test. Our strict control standard keeps garment length shrinkage below 2%. For high-standard European and American brands, we can use pre-compacted denim materials and optimize cutting layouts to further stabilize sizes. Before shipment, ASAHI·LINK conducts independent shrinkage detection and stitching strength inspection to issue official qualified reports. Our factory supports full-process shaping craft customization and third-party quality certification for global unisex denim shirt suppliers.
