Detailed Explanation of Core Crafts in Luggage and Bag Making
I. Cutting Craft Techniques
Cutting is the primary preparation work in the luggage and bag making process. Compared with mechanical cutting, manual cutting is more flexible, especially suitable for leather materials. During operation, leather parts can be freely selected according to needs, which can not only effectively avoid defects but also maximize the use of leather.
II. Skiving Craft Techniques
When using leather materials, especially thick ones, skiving (thinning) is required. This process lays the foundation for subsequent steps such as gluing, folding, and binding, and also significantly improves the overall softness of the finished bag. It can be said that the skiving craft determines whether the hand feel of the finished bag can meet the original factory (ZP) quality standards.
III. Tabletop Craft (Adhesive Selection)
In high-end luggage and bag making, the selection of adhesives is crucial and needs to be made according to the area of the bonding position and the characteristics of the materials:
• Large-area bonding: Italian intercom spray adhesive is suitable, which needs to be used with an air pump. This adhesive is white water-based with strong fluidity, applicable to leather, microfiber, leather bran paper, etc. It has the advantages of low odor and meeting European environmental standards, so it is often used in luxury goods production. The price is about 700 - 800 yuan per bag, and it will not make the material hard after large-area bonding.
• Local high-strength bonding: For local parts that require high-strength bonding or no subsequent stitching, yellow glue is a better choice. Yellow glue has strong compatibility and firm bonding, which can meet the bonding needs between various materials.
IV. Folding and Binding Crafts
Folding and binding not only play a decorative role but also reflect the quality:
• Binding craft: Such as the binding craft often used in traditional handmade bags, although it takes a long time and has extremely high requirements for the calculation of the early version and the control of the edge thinning thickness, compared with edge oil treatment, binding has a longer service life and the finished product effect is more exquisite and beautiful.
V. Edge Painting/Grinding Craft
Edge painting is one of the core difficulties in the production of luxury bags, which completely relies on manual operation and requires multiple grinding processes. This process has strict requirements on the craftsmanship, leather quality, and the selection of edge paint materials, and its technical level has also become an important standard to judge the quality of luggage and bags.
VI. Hardware Installation Craft
There are various types of luggage hardware, and the installation methods are different:
• Ring buckle hardware: Such as ears, handles, etc., are usually clamped at the folded part of the material and fixed by machine sewing.
• Decorative/functional hardware: Including eyelets, rivets, leather foot nails, magnetic buttons, hardware labels, etc., which need to be installed with a nailing machine or by hand.
VII. Machine Sewing Craft
The use of German imported Durkopp sewing machines is the guarantee of high-quality machine sewing. As a top brand in the field of leather sewing machines, Durkopp sewing machines can provide dense and full stitches, ensuring a stable and smooth sewing process. At the same time, they are flexible and convenient to operate, and can accurately and neatly complete various decorative stitches and拼接 stitches, whether it is single-needle/double-needle open sewing, inlaid line sewing or splicing sewing.
