With its excellent physical properties and process adaptability, high-strength nylon wire is better than inferior wire rod in terms of durability, wear resistance, color fastness and detail treatment, which is one of the core criteria to measure the quality of bags.

1. Durability and tensile resistance: Eliminate the risk of breakage at the root

The high-strength nylon thread is woven from polymer polyamide fibers, with a compact molecular structure and 3-5 times the tensile strength of ordinary cotton thread. Keep stitches intact even when subjected to heavy objects (e.g., the contents of a commuter bag) or open and close frequently (e.g., zippers) over long periods of time. On the other hand, inferior threads (such as low-count polyester or recycled cotton threads) are loose and easy to break, and they are prone to burrs or even broken threads under the friction of hard objects such as keys and mobile phones, resulting in deformation of the package body or falling off of the items.

2. Anti-wear and corrosion resistance: adapt to multiple use scenarios

Nylon threads have a smooth surface and a low coefficient of friction, making them excellent in high-wear areas such as bag edges, shoulder strap seams, etc. Its chemical resistance makes it able to cope with complex environments such as sweat, rain and even cosmetics spills, and it is not easy to age and become brittle after long-term use. Inferior threads are more likely to lose their load-bearing capacity due to mildew due to mildew due to rough material due to rough material and easy to swell and deform when exposed to water.

3. Color fastness and aesthetics: details determine texture

The high-quality nylon thread is dyed at high temperature with environmentally friendly dyes, and the color fastness can reach more than 4 (the highest grade 5 in the national standard), and the color is still bright even if it is exposed to direct sunlight for a long time or rubbed against dark clothes. In order to reduce the cost of inferior threads, industrial dyes are used, and the color fastness is often less than grade 2, and the slight scratch will be white and faded, resulting in "alopecia areata" color difference on the edge of the bag, which seriously affects the appearance.

4. Process adaptability: support precision sewing standards

The high-strength nylon thread has good ductility and resilience, so that it can perfectly adapt to the precise stitch length requirements of "3-4 stitches per centimeter". This standard of craftsmanship is particularly crucial in bags from luxury brands such as Valentino, where it ensures the structure of the silhouette. Due to the lack of elasticity of inferior threads, forced high-density sewing will cause the stitches to twist and the seams to wrinkle, which will lay a hidden danger for the thread to fall off.

Suture material - the invisible watershed of quality

The gap between high-strength nylon thread and low-quality thread is essentially a game of industrial standards and cost compromise. The former provides the underlying guarantee of "anti-aging" for bags through material technology and process precision; The latter has a short-term cost advantage at the expense of the product's service life and user experience. For consumers, observing whether the color of the stitches is in harmony with the leather, whether the stitch distance is even, and whether the seam is flat are practical tips to quickly identify the quality of a bag – true luxury is often hidden in invisible details.
