Strong, durable threads designed for stitching leather goods with a sewing machine are essential for creating robust and lasting seams. These specialized threads are typically made from materials like bonded nylon, polyester, or linen, often coated or waxed for added strength, smooth passage through heavy materials, and resistance to abrasion. An example would be a heavy-gauge bonded nylon thread used to construct a leather bag.
The use of appropriate stitching materials significantly impacts the final product’s quality and longevity. Robust threads ensure the seams withstand stress, preventing unraveling and maintaining the item’s structural integrity over time. Historically, linen and waxed threads were primarily used; however, advancements in material science have led to the development of synthetic options with superior strength and durability. This progress enables the creation of high-quality leather goods capable of withstanding significant wear and tear.
