Whether the fabric is good or bad has a huge impact on the condition of the seam. For example, some well-organized fabrics, finished fabrics, and thinner, non-stretch fabrics. When clothing sewing school's sewing direction is parallel to the warp direction of these fabrics, the embedded stitch will force the warp yarns away from the original position, because each stitch will push the warp yarn away, and the deviation generated by multi-needle accumulation will be along the The seams of the seams shrink and cause the seams to wrinkle. When the sewing direction is parallel to the weft direction of these fabrics, they are usually less wrinkled. Experience has shown that diagonal seams in the diagonal corners do not wrinkle. Most fabrics, provided that the seams are at a 15 degree angle of latitude or longitude, are sufficient to avoid wrinkling. Therefore, you can consider using oblique cutting mode. If necessary, apply a smoothing agent to the fabric.
In addition, fine needles should be used as much as possible. Since the fine needle can significantly reduce the resistance generated when passing through the fabric, there is an effect of preventing the crease from wrinkling, and it is necessary to pay attention to changing the new needle frequently.
When using a synthetic sewing thread, the tension of the thread must be carefully determined and the tension should be adjusted to a minimum. The tension of the bobbin thread must be adjusted so that when the free end of the thread is pulled up, the bobbin of the bobbin thread and the outer sleeve slowly slide downwards. The tension between the upper thread and the lower thread must be the same so that they interweave between the two layers of fabric. If the synthetic sewing thread is sewn into the fabric with too much tension, it will automatically shrink to relieve this tension. This phenomenon will shrink the seam along the seam and cause the seam to wrinkle.
Also note that the friction between the upper fabric and the presser foot forces the lower fabric on the feed dog to move more quickly and cause the seams to wrinkle. Garment label, clothing label, woven label, metal label supplier. The garment making school can eliminate the wrinkles caused by feeding as long as the pressure of the presser foot is reduced as much as possible, and the feeding teeth (conveyor) with fine teeth are used at the same time to reduce the speed of the sewing machine, and the fundamental method to completely solve this problem is solved. A sewing machine with a differential feed or needle feed mechanism is used.
