nylonwound

nylonwound is a descriptive term used to denote constructions in which nylon is used as a winding, coating, or sheath around a core or substrate. It is encountered in several industries, most notably in musical instrument strings and in certain forms of wire insulation and technical yarns.

In wire and cable applications, nylon winding provides abrasion resistance, low friction, and environmental protection. A nylon layer is wound around a metal or polymer core to improve flexibility and durability in moving or exposed environments. However, nylon absorbs moisture from the air, which can alter dimensions and strength, so products are designed with that factor in mind and may include moisture barriers or sealing.

In classical guitar strings, nylon-wound strings have a nylon core with a metal winding—typically copper or silver-plated copper—around the lower strings. The winding adds mass and changes the tonal character, producing brighter timbre and increased durability at the expense of some tension, compared with plain nylon strings. Proper setup, humidity control, and compatible fittings on the guitar are important for optimal intonation and longevity.

In textile and fiber technology, nylon may be wound around a filament or core to form filament yarns, cords, or rovings. Wound nylon constructions can tailor stiffness, strength, and handling properties for technical fabrics, ropes, or cordage. Manufacturing controls winding tension, adhesion between layers, and moisture content to ensure consistent performance.
