Line is one of the necessary materials in production. When preparing for production, we must first adjust the needle spacing and stitches. The general requirements are: clear stitches, straight stitches, moderate tightness, no thread throwing and needle jumping. Wiring is not allowed on the surface of the bag body, especially the boutique bag. Dark wire is allowed to have wiring, but it must be heavy wire 7 ~ 10 needles, and it's good to return the needle. According to the requirements of different luggage products to choose the line, do not arbitrarily use different colors, specifications of the line. The following is the specific operation process: first, positioning. That is, two or more layers of materials are fixed together, and the front and back sides of the materials and the direction of the pattern must be clearly recognized before positioning. Generally, the positioning stop is required to be 2 ~ 5mm, not too wide, the surface fabric should be flat, not wrinkled, not twisted. There should be no wired head, sundries, dirty spots, etc. in the interlayer, especially those with light colors. Second, pour the needle. The reverse needle is to increase the firmness. In addition to the need to reverse the back and forth needle for the joint, the place that needs to be loaded is also required to return the needle, such as the two ends of the zipper, the belt, and the pendant. The back and forth needle must fall on the same straight line. Third, the trademark. The trademark is the logo of the product. It is not allowed to be sloppy. Before the car, it is necessary to check whether the graphic of the trademark is clear and whether it is skewed (Including printing labels, weaving labels, leather labels, washing labels) Under normal circumstances, the needle is raised and closed at the bottom of the trademark ~ 4 needle and thread, and must focus on a straight line. Strictly follow the positioning seam, the material has a positioning hole or a positioning point, and the trademark must cover the point. Printing and weaving labels cannot be exposed or skewed when sewing. Fourth, joint. Seaming is to put two layers of fabric together, which is the main process on the bag. It is required to stop the mouth straight, the width is consistent, and the needle should be poured back and forth, 2 ~ 3 Needles. Five, zipper. The zipper is the most important of all the parts on the bag. Its quality must be perfect. The zipper and zipper head are not allowed to have quality defects. When the chain is zipped, the direction of the zipper head cannot be reversed, the distance between the zipper teeth and the material edge is 3mm, and the mouth should be uniform and straight. If you need a double line, the double line should be uniform and straight, and the side material and zipper should be flat, and there should be no waves. Six, surrounded. The appearance of the whole package is inseparable from the surrounding. The attachment should be aligned with the positioning gap, the zipper tail cannot be spread out, and the double line needs to be even and straight. If the attachment is too long or too short, the closed bag will be skewed or wrinkled, in principle, the package must be tried before it is surrounded, and it can be produced only when it is suitable. Seven, embedded line. The inlay is the skeleton of the bag. According to the requirements of different styles of bags, the inlay of different materials should be selected. The inlay should be tightly wrapped and the upper and lower stops should be uniform. The inlay generally requires the inlay feet to be aligned with the fabric margins, the edge of the inlay should be straight, the corner should be smooth, the rounded corners should be round, the four corners should be uniform, and the patch with the patch should be centered and tightly attached. Eight, the package. Packing is the main process of bag forming. For bags with embedded lines, packing requires full packing and cannot eat embedded lines. The size of the surrounding and the body piece should be appropriate. When the surrounding is too large, the surrounding will wrinkle. When the surrounding is too small, the bag will be easily deformed, and the bag will appear. It should be noted that the direction of the zipper head cannot be reversed (Refers to a single zipper head). To distinguish the front and back, the package is mainly to pay attention to the symmetrical effect, including the front and back, left and right, up and down. Nine, Hemming. The Hemming is divided into outer Hemming and inner Hemming, especially the outer Hemming requires uniform and straight width, uniform width, smooth corner and round corner. The Hemming belt must cover the joint wrapping line, and the fabric at the edge of the Hemming belt cannot wrinkle, there should be no slip bag or missing bag. For bags with embedded lines, be careful not to eat embedded lines when wrapping inside (Refers to the car to the embedded line). The weaving head should be folded or scalded according to the requirements, and the straight receiving head needs to be poured back and forth, and must be poured on the same straight line. Ten, copy the edge. The edge of the seam should be uniform and straight, the width is uniform, and the corner is smooth. The edge of the seam should be copied on the outside of the suture, and the seam edge cannot be removed. More information is available at Pesin Outdoor Products Company!
