![]() As the surface is very smooth, knots slip easily.ĭyneema® is used in stitched slings and accessory cords. It is extremely strong with a tensile strength of 3,400 N/mm2 but has a very low elongation at break of 3.8%. It is slightly more abrasion resistant and primarily used in sewn and non-sewn formats in webbing constructions.ĭyneema® is the brand name for ultra-high-molecular-weight polyethylene (UHMWPE). Polyester has the same breaking strength as polyamide and a lower elongation at break (10–20%). It is both intertwined into ropes and accessory cords with a kernmantle construction and interwoven into webbing constructions. This is why-compared to high-strength materials such as Dyneema® (UHMWPE) or aramid-more material has to be incorporated into products made from polyamide to achieve the same strength. At 15–30%, it has the highest elongation at break of the four materials but only a medium tensile strength of 800 N/mm2. Polyamide (PA) is the most widely used material. A highly stretchy material can compensate for these tension peaks more so than a static material as the fibers subject to the most tension stretch, placing the load on additional fibers.įour materials are used for the textile fibers in ropes, slings, and accessory cords: The cross-section shape (round, rectangular) and dimensions together with the material's elongation at break affect the impact of the uneven load distribution due to the knot. Tension peaks occur in the material, which can break at these points when subjected to a certain load. The fibers in bent material are compressed, meaning that some are subject to less tension than others (see Figure 1). The knot's bend radius is a key factor and is influenced by both the knot type and the direction of the load on the knot. All gear should naturally hold, but how much safety reserve remains? Which textile with which knot is particularly ideal for which purpose? To answer these questions, we have tested the most important combinations.Įssentially, a knot reduces the strength of textile materials due to the imbalanced distribution of the load on the fibers. The material and construction, as well as the knot type and load direction on the knot affect the extent to which the strength of the starter material is reduced by the knot. And the knot to help it stay there.Textile ropes, slings, webbing, and accessory cords are standard pieces of climbing equipment and almost always knotted when used. With a wide variety to choose from, we’ve got the tie your neck has been missing.

Wearing your necktie too tightly can greatly decrease blood flow to the brain.That’s a lot of time spent in front of the mirror. It’s reported that there are over 100,000 different ways to tie a men’s tie.The first ties were worn by Croatian soldiers.One quality silk tie requires over 120 silkworm cocoons and about 54,864-99,060 meters (180,000-325,000 feet) of silk thread!.The British stripes were designed to run from a person’s heart to their sword. Stripes on classic American ties go from the top right to bottom left in order to distinguish them from British Regimental Stripes that run from the top left to the bottom right.If you know Irene, ask her to check out our selection to help her keep her Guinness World Record.
