How to implement a rigorous quality control system from yarn to garment?

At the start, let’s inspect the quality of the Garment Yarn.

First step to adopting a quality system should still be with yarn, the basic building block of garments, Before yarn reaches the production line, it’s crucial to evaluate a few quality indicators such as fiber composition, strength, and evenness of the yarn. This includes proper assessment of yarn composition to avoid issues such as an inconsistent fabric feel as well as mitigating issues related to yarn breakage during weaving and, consequently, defects in the final garment. Only yarn that passes the specified quality test should be allowed to proceed to the next production step; this initial check eliminates quality risks from the very source.

Quality Control During Weaving and Knitting Processes

Once qualified yarn has been chosen, the weaving or knitting quality control processes become crucial. During these, quality control requires real-time supervision. In the case of weaving, control should be on fabric density and alignment with the warp and weft. If the density is uneven, the garment will look unbalanced and will not fit properly. In the case of knitting, control should be on stitch consistency. After washing, loose or tight stitches will cause the fabric to distort. Control should be pictorial and taken at regular intervals. Any fabric with defects should be marked and handled immediately to ensure it does not pass on, allowing the semi-finished fabric to meet quality standards.

Final Fabric Cuts Quality Check: Ensuring Accuracy of Pattern Shapes and Fit

The first step in making a garment is cutting fabric into garment pieces, and accuracy in this step directly impacts how a garment will fit in the end. Prior to cutting, confirm that the pattern size corresponds with the design specification – even a tiny discrepancy can result in a poorly fitting garment. When cutting, confirm the alignment of the fabric's grain lines. Cutting against the grain can result in the garment stretching and/or shrinking unevenly. In addition, check the cut piece edges to ensure that loose threads are not present. Frayed edges will not only make sewing the garment pieces together more difficult, but will also considerably wear the garment out. Ensuring these will allow each cut piece to maintain consistency which will ease the sewing process.

Ensuring Quality in the Sewing Process  

As the sewing stage progresses, the pieces that comprise the garment get assembled. At this stage, the garment should undergo quality inspection as it should meet the requirements in the structure and appearance. Start by inspecting the sewing thread. The thread should be compatible with the fabric in material and strength, otherwise it will break or damage the fabric. Next, examine the density of the stitches and the seams. Insufficient stitch density can lead to the seam splitting and uneven seams will cause the garment to look unappealing. The important parts also need to be checked. The cuffs, collars and hems get misaligned and stitched loosely more often than other parts and this will affect garment usability the most. Defective sewn semi-finished products should be repaired or reworked. This will prevent quality issues from accumulating in the sewing stage.

Final Garment Inspection: Ensure Compliance With Delivery Standards

The final inspection is the last barrier to ensuring quality before delivery. This spans multiple steps: first, the overall appearance for defects such as stains, loose threads, or uneven coloring needs to be examined. Next, the garment size and fit need to be checked by dressing the garment on a standard mannequin to see if it aligns with the size chart. After that, washing and ironing tests need to be conducted to observe shrinkage, color fading, or deformation of the fabric. These tests are meant to simulate everyday use to see if the garment will hold up to quality after being washed. Only the garments that pass all of these final checks will be deemed qualified for delivery, ensuring customers are receiving high quality standard products.
