The strength of the overlocking thread is not required to be high, which can be made from sewing threads or polyester filaments without twisting.
An overlock stitch is used for edging, hemming, and seaming fabric. Understanding how seams and threads interact is essential for clothing fabrication. In clothing production, there are approximately 30 stitch types and 300 seam variants. Consequently, there are numerous stitch and seam combinations for garment construction.
The T-shirt construction is a notable example. T-shirt bodies, sleeves, and trim pieces are bundled and labeled before being delivered to the sewing room. This ensures correct matching during assembly. The main assembly stages include bottom hemming, shoulder closure, neck trim insertion, off-line sleeve assembly, sleeve insertion, and shoulder taping.
Compared to T-shirts, the production process for jeans requires a higher number of components and assembly stages. Denim, an open-width woven fabric, differs from tubular knit fabrics and requires stretching and cutting in a specific direction. Furthermore, the cut parts must be labeled accurately and matched for shading. Numerous off-line stages are required before combining components to construct a pair of jeans.
Dress shirts are complex garments that utilize interlining and buttons, in addition to the primary fabric, for construction. The manufacturing process is largely automated, resulting in a high-quality product with minimal variability.
