[Leather Process] The main production process of leather goods, leather crafts refers to the various processes, production methods and production techniques in the production of leather goods, which is an important part of reflecting the quality and grade of a product. The following is a brief introduction to the main production process of leather goods such as binding, inner seam, open seam, inner seam of bale, covered seam, oil edge, hemming edge and semi-clear seam.
Flat seam - refers to a process of joining single or multi-layer overlapping parts by means of a sewing machine (ie flat car), which is the most used one in leather sewing, and is suitable for the components in the opposite plane of leather products. Processes such as joining or sewing decorative lines.
The inner seam, also known as the dark seam or the buried pocket, is a traditional process in which the edges of the two parts are sewed face to face and then turned over, so that the joints of the parts are not visible but the stitches are not visible. There are a variety of methods for sewing the sewing machine or the high-end sewing machine after the initial hand sewing and industrialization, which is suitable for the connection of the internal and external parts and the manufacture of the soft handbag.
The bright seam, also called the outer seam, refers to a traditional process in which the inner layers of the two joined components are relatively fitted and sewn, and the upper and lower threads can be seen. There are also methods of hand-stitching and high-end sewing, which are suitable for the final sewing process of the bag mouth and the cross-head three-dimensional structure of the soft body and the shaped handbag.
Bundle inner seam - is a decorative traditional process of sewing the edge of one of the parts to the edge of the bone and then sticking it together with the edge of another related part to make the inner joint. It is suitable for the design of the lattice structure of the soft handbag or the shaped handbag. Production.
Bundled seams - a decorative edge made of a decorative edge between the edges of the two parts of the oil or the hem, suitable for the design of various package products.
Edging and quilting - is a decorative traditional process of sewing a strip of a certain width (or artificial leather strips, cloth strips, etc.) to the edge of a flat part or a three-dimensional structure, with a hem, The edging of the one-sided hem, the hem of the double-sided hem, and a variety of reverse edging and nylon webbing. The edging of the flat parts is sewn with a flat sewing machine, and the edging of the three-dimensional structure is sewn with a high-end car, which is suitable for the design of all leather products.
The oil edge - also called the slick oil edge, polishes the edge of the leather goods parts or the three-dimensional contour of the fit, and then rolls a layer of leather edge oil to decorate the traditional craft. The method of oil edge can be divided into two different processing techniques, thick oil method with different processing techniques and thin oil method with only edge color improvement. The thick oil method is suitable for the processing of relatively high-grade leather products, requiring smooth and full edges; the thin oil method is common to both soft and hard leathers, but its edges can be seen with rough fibers and conforming gaps, which are mostly used for the processing of casual handbags.
Folding - shovel the edge of the product part or apply glue directly on the edge of the lining or man-made material (or paste double-sided adhesive tape), then fold the inside layer 2 or 2 minutes (English length unit 1 A conventional process of 1 / 8 inch), suitable for the processing of various artificial leather packaging materials and leather products.
Semi-clear seams - a fashion process in which different parts of the various layers are combined into a three-dimensional structure and then sewn with a special column car or a moving head car. This kind of process is suitable for sewing the bottom of the bag and the three-dimensional type of skin which can not be turned over, and has the three-dimensional process effect of seeing only the upper line and not the bottom line. In addition, the flat sewing machine sews the same layer of parts, and only sees the upper thread after the assembly without the bottom line. The difference is that the flat sewing machine is suitable for plane sewing, and the column car and the moving head car are suitable for three-dimensional sewing.
The above is an important process for the design and manufacture of leather goods. In addition, there are many other processes in the production assembly process that are also necessary for manual workers in various process flows. For designers, it is only required to have a certain degree of understanding of various processes in actual work, and can be used as a reference factor for product design. When designers want to make changes to some key processes, they should use illustrations or words to supplement explanations and oral explanations, emphasizing the special effects and changes after the process changes.
