It is a well-regulated and practical gift customization. In backpack customization, the fabric and accessories are the first image performance, and the second is the craftsmanship details, especially the sewing thread. The quality gap can be seen quickly.

The sewing thread of custom-made backpacks has functional and decorative functions, and the sewing technology directly affects the sewing efficiency, sewing quality and appearance. There are many kinds of sewing threads, and there are two kinds of sewing threads customized for backpacks.

1. Natural sewing thread

Natural fiber sewing thread includes cotton thread and silk thread. These two threads have good dimensional stability and excellent heat resistance, but their strength is relatively poor. Currently, they are mainly used for hand-sewing and fixing. Pure handmade products often use natural sewing threads, which have a natural and original handmade feel.

2. Synthetic fiber sewing thread

The main characteristics of synthetic sewing thread are high tensile strength, small washing shrinkage, good wear resistance, moisture resistance and not easy to be corroded by bacteria. Moreover, its raw materials are sufficient, low price, and good seamability. It is currently the most widely used, the variety with the best practical performance.

Classification of sewing thread for backpack customization

Among synthetic sewing threads, polyester threads and nylon threads are the most widely used. Among polyester threads, there are three commonly used polyester threads, polyester filament threads, and polyester filament elastic threads. Among them, ordinary polyester thread occupies a dominant position due to its low price, high strength, wear resistance and good chemical resistance. Polyester filament thread has high oil content, fewer joints and higher strength, so it is mostly used for sewing military products. The polyester filament elastic sewing thread is mainly used for sewing elastic fabrics.

In the sewing of luggage products, polyester thread is mainly used for sewing lining or auxiliary materials, and sometimes for surface sewing of thin fabrics or textile fabrics. Nylon thread has three types: long filament thread, short fiber thread and elastic deformation thread. At present, the main variety is nylon filament sewing thread. Compared with polyester thread, it has stronger strength, better elasticity, light weight and good gloss, so, in the sewing of luggage products, nylon thread is mainly used for sewing fabrics.
