Second: Fill in Melody. Made of 100% pure cotton, it must be neat and clean, with no less than 25 layers, and no folds between layers. The bottom trimming must have a margin of 1.5cm, and it must be smooth and not deformed.
Thirdly, the sole is also one of the most important links in production. Keep the soles clean when laying. When laying lines and edges in a cross way, do not deform. The stitches should be arranged neatly, and there should be no distortion. When laying the sole evenly, the force should be appropriate, and the surface of the sole should not be uneven, otherwise it will be regarded as unqualified.
Fourth: cut the bottom edge. First, the accepted soles should be leveled with a hammer to make the soles soft and more comfortable to wear after becoming shoes. The second is trimming, that is, taking the remaining edge of the finished sole and cutting it off with a special tool. It needs to be smooth when cutting, and no obvious knife marks can be left. The third is to use high-quality cotton and spread it on the soles. The fourth is sewing interlining.
Fifth: cut the vamp. Adopt high-quality upper lining as lining material. The fabrics are all cotton, satin, silk and embroidery. First, cut the lining into samples, then smooth the fabric and lining with a slurry lake, and then bond the reverse side with a special interlining. After air drying, you can proceed to the next step.
Sixth: Sewing uppers. After air drying, cut off the excess parts of the sample, and then sew it first. Sewing is very important, the needle distance should meet international standards, and the needle should be straight when walking straight. When turning a corner, you should bend the needle, not twist it. The roll cloth and the edge strip must be tightly pressed, and there should be no looseness or wrinkle when sewing the edge. At the same time, keep the rubber strip clean.
Seventh: shoes. Traditional hand sewing is adopted. When upping, we should grasp the matching scale of the vamp and sole, the stitch distance should not be too large, the stitches should not be skewed, and the left and right sides of the vamp should be aligned and should not exceed the edge of the shoe.
Eighth: last. A good pair of shoes must be shaped by a shoe last. The specifications of the shoe last must be consistent with the size of the shoes, so that the shoe last will be beautiful and fit.
Ninth: dressing and dressing. Dressing is to cut off the redundant thread, remove the foreign matter on the upper, and then smooth the raw edge of the sole with special materials, dry it and then test it.
