Touw

Touw is the Dutch word for rope. In general use, a rope is a thick, flexible line made by twisting or braiding fibers to form a continuous length that can bind, lift, pull, or secure objects. Rope has longstanding practical value in maritime, forestry, construction, and climbing.

Ropes can be made from natural fibers such as hemp, sisal, manila, or cotton, or from synthetic fibers such as nylon, polyester, and polypropylene. They are constructed as laid (three or more strands twisted together) or braided, and some types use a core-and-sheath design (kernmantle) in which a central core carries most load and an outer sheath protects it. Natural fibers tend to rot in moisture; synthetics offer higher strength and durability but may degrade under UV exposure or chemicals.

Common forms include plain laid rope, braided rope, and specialized types such as kernmantle climbing ropes and marine mooring lines. Ropes are rated for breaking strength and working loads, and selection depends on the task and safety factors. Regular inspection is required to check for fraying, cuts, glazing, stiffness, or heat damage, and damaged rope should be retired.

Rope-making has ancient roots and evolved with industrialization and the adoption of synthetic fibers, expanding performance and application ranges.
