Pay attention to those matters when sewing Dongguan work clothes:
When the sewing direction is parallel to the warp direction of these professional wear fabrics, the embedded stitches will force the warp yarns out of place, because each stitch will push the warp yarns away, and the deviation caused by the accumulation of multiple stitches will follow The body of the seam shrinks and causes wrinkling in the car. When the direction of sewing is parallel to the weft direction of these professional dress fabrics, it is usually less wrinkled. According to experience, the diagonal seams in the diagonal will not wrinkle. Most professional wear fabrics are sufficient to avoid wrinkles as long as the seam is at a 15-degree angle of longitude or latitude. Therefore, you can consider using diagonal cutting. If necessary, apply a smoothing agent to the business attire. Also, use fine needles as much as possible.
Because the fine needle can obviously reduce the resistance generated when passing through the professional wear fabric, it has the effect of preventing the shrinkage and wrinkle. At the same time, pay attention to changing the new needle frequently.
When using synthetic sewing thread, care must be taken to determine the tension of the thread, and the tension should be adjusted to the minimum. The lower thread tension must be adjusted: when the freely moving end of the suture is pulled up, the lower thread bobbin and jacket slowly slide down, and the tension between the upper thread and the lower thread must be consistent, so that they are exactly between the two layers of professional wear fabric Intertwined. Synthetic sewing thread is too tight to be sewn into the business dress fabric, and will automatically shrink to relieve this tension. This phenomenon will shrink the cloth body along the seam, and then the seam will wrinkle.
