The luggage master will share with you the manufacturing process of leather goods and luggage products!

Trolley cases are unavoidable when you travel and travel on business trips. Trolley cases have become daily necessities in people's lives. People not only pursue the volume and capacity of trolley cases, but also have more and more different views in terms of appearance.

The details of the production process of leather goods and leather products are as follows:

Bundled edges-used to form a variety of side bones to set off or enhance the shape of the handbag. The side bones have coreless skin bones, leather cores with rubber cores, cotton cores, springs or steel wire cores, artificial material side bones and rubber bones without cladding.

Flat seam-refers to the use of a flat seam machine (ie flat car) to connect a single layer or multiple layers of overlapping parts. It is the most common process used in leather sewing. It is suitable for all parts in the relative plane of leather products The process of connecting or sewing decorative thread.

Inner seam-also called concealed seam or buried bag, is a traditional process where the edges of two parts are stuck together face to face after sewing and turned over, so that people can see the seams of the parts but not the stitches. There are early sewing and sewing machine after industrialization or high

Various methods of sewing the head car are suitable for the connection of internal and external parts and the production of soft handbags.

Open seam, also known as outer seam, refers to a traditional process of sewing the inner layers of two connected parts relatively to each other so that the upper thread and the lower thread can be seen. There are also hand-sewing and high-end sewing methods, which are suitable for the * sewing process of the mouth of the soft and stereotyped handbags and the three-dimensional structure of the horizontal head.

Bundled inner seam-is a decorative traditional process in which the edge of one part is sewn to the side bone and then attached to the edge of another related part for inner seam. Make.

Open-seam of bundle edge-It is a decorative process made by inserting a decorative rib between the edges of two parts of oil edge or folding edge, which is suitable for the design and manufacture of various bag products.

Overlock seam-a decorative traditional process of wrapping a certain width of leather strips (or artificial leather strips, cloth strips, etc.) on the edge of a flat part or the contour of a three-dimensional structure. Single-sided hemmed hemming, double-sided hemmed hemming, and a variety of reverse hemming and nylon webbing inner hemming. The hemming of flat parts is sewn with a flat sewing machine, and the hemming of a three-dimensional structure is sewn with a high-end sewing machine, which is suitable for the design and production of all leather products.

Oil edge-also known as loose mouth oil edge, after polishing the edge of leather product parts or the three-dimensional contour of the fit, roll on a decorative traditional process of a layer of leather edge oil. The method of oil edge can be divided into two kinds of thick oil method with different processing technology and different processing technology and thin oil method with edge color improvement only. The thick oil method is suitable for the processing of relatively high-end leather products, requiring smooth and full edges; the thin oil method is common to soft and hard leathers, but its edges can see rough fibers and fitting gaps, which are mostly used in the processing of casual handbags.

Folding-shovel the edges of the product parts thinly or apply glue (or paste double-sided adhesive tape) to the edges of the lining and man-made materials, and then fold the person into the inner layer for 2 minutes or 2.5 minutes (inch length unit 1) Minutes = 1/8 inch) is a traditional process, suitable for various artificial leather bag materials and genuine leather parts processing.

Semi-open seam——It is a fashionable process to sew the parts of different layers into a three-dimensional structure and then sew them with special column cars or shaking cars. This process is suitable for sewing the bottom of the bag and the three-dimensional surrounding skin, which can not be turned over, and has the three-dimensional process effect of only seeing the surface line without seeing the bottom line in appearance. In addition, the sewing machine sews the parts on the same layer. After assembly, it can only see the upper thread and not the lower thread. The difference between them is that the sewing machine is suitable for plane sewing, and the column sewing machine and the shaking machine 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 and assembly process, which are also techniques that manual workers must master in various process flows. For designers, it only requires a certain degree of understanding of various processes in actual work, and can be used as a reference factor for product design. When the designer wants to make changes to some key processes, it is necessary to supplement the explanation and oral explanation with icons or words, emphasizing the special effects and changes after the process changes.
