Bending edge machine manufacturers for you to introduce the sewing process common defects have? Some of the major problems we have with sewing machine equipment:
(1) The defects caused by the needle, such as broken holes, broken yarn(knitted fabrics), drawn yarn(woven fabrics), etc., are mostly improper in the selection of the needle, and the needle surface is flawed, not smooth, and the needle tip is bent. The needle temperature is too high. Synthetic fibers are also prone to needle holes.
(2) defects caused by needle plates, delivery teeth and pins, and defects on the surface of needle plates or pins, causing the seams to be drawn or hooked; The pressure of the foot is too large to cause tooth marks; The newly replaced cloth teeth cause tooth marks, and the unpolished cloth teeth also cause yarn or hair.
(3) Jumping needles, due to improper selection of sewing machine needles, improper adjustment of sewing mechanisms, too much sewing thread twist or undesired, artificial action mistakes, etc. are easy to cause needles.
(4) Broken wires, incorrect adjustment of sewing machines, improper selection of needle, operator movement mistakes, and high temperature of needle can all cause fracture of stitches.
(5) Uneven needle distance, damaged or improper device of the conveyor, incorrect movement of the operator, sewing machine and fabrics are not adapted, will cause uneven needle distance.
(6) The thread is too loose or too tight. Due to the fact that the bottom and surface lines are too small or too large, the operator pulls the fabric unequally or improperly, causing the thread to be too loose or too tight.
(7) The thread trace structure is improper. Different seams, seams, and different positions should be selected. For example, the edge of the envelope should be selected for the thin material, while the thick material should be selected for the 505 thread trace. The result is very different.
(8) White spots at the needle's eye. For the pigment-colored fabric, due to the limited penetration capacity of the dye, the surface reaches saturation and the interior has not been dyed. When the needle is punctured, the internal unstained fibers are pulled out together, resulting in white spots at the needle's eye.
(9) The color of the fabric is inconsistent with the color of the suture. Usually the color of the suture is consistent with the fabric. The deep color of the suture is also a common rule, but the color of the suture is too light. The effect is not good unless the customer has a specific request.
(10) Oil stains or stains, which are easily caused by oil leakage or unclean work sites due to the lax sealing of the oil routes of sewing machines.
(11) Blasting edges, due to the small size of the seams, loose tissue structure of the seams, and excessive trace density, the force on the seams causes the seams to burst edge, also known as seams, seams, etc..
(12) The seams are biased. Because the operator's sense of responsibility is not strong, mistakes are made during the feed. The seams are out of the seams and cause slits(also known as the next gongs). When the seams are continued, they may cause seams(also known as gongs).
(13) Poor paper clips, insufficient amount of paper clips when starting and stopping needles, prone to the phenomenon of thread dislocation, paper clips deviate from the original line trace position and cause uneven seams.
(14) The position of the seams is uneven. Due to poor grasp of the eating potential, improper tension of the stitches, and mistakes in the operation, the seams are uneven, distorted, and wrinkled.
(15) The folding edge is distorted, and the initial positioning of the folding edge is not accurate. When the suture is done, the surface and the bottom food force are not uniform, resulting in distortion at the folding edge.
(16) Incorrect bars or patterns, careless sewing, improper skills, causing dislocation when sewing seams with bars or patterns.
(17) Asymmetric seams, asymmetrical armbands or cross seams, mostly due to insufficient skills of the operator or improper cutting design.
(18) Sew residual cloth, poor grasp of eating potential, resulting in seams residual cloth.
(19) The front and back of the garment are reversed. Due to a smooth phenomenon caused by the dressing, there are positive and negative errors in sewing.
(20) The lines are not straight. Due to insufficient skills or sense of responsibility, the seams are not uniform and there is a bending phenomenon. When the two lines are sewn, the lines are not parallel and they are not straight.
(21) After the stitch is washed, the fabric is wrinkled or colored. After the wash, the difference between the fabric and the stitch shrinkage is too large, resulting in the phenomenon of stitch shrinkage(larger stitch shrinkage) or loose(smaller stitch shrinkage). Insufficient color fastness can easily cause the phenomenon of matching.
