What is tenacity?
In textiles, tenacity is a measure of a fiber’s strength and durability. Specifically, it refers to the amount of force required to break a fiber under tension. Tenacity is an important property to consider when selecting fibers for use in textiles, as it affects the performance and lifespan of the finished product.
Tenacity is typically measured in grams per denier (g/d), which is the weight in grams of a 9,000-meter length of fiber. For example, a fiber with a tenacity of 3 g/d means that it would require 3 grams of force to break a 9,000-meter length of that fiber.
Fibers with high tenacity are typically stronger and more durable, making them suitable for use in products that need to withstand heavy use or stress, such as ropes, seat belts, and industrial fabrics. Examples of high-tenacity fibers include nylon, polyester, and aramid fibers like Kevlar.
