Question

Tenacity is the term used for the strength of

• A. Fiber
• B. Yarn
• C. Fabric
• D. Cotton

Hint:

• Tenacity A measure of strength per unit linear density (e.g., grams/denier, cN/tex).
• It is most fundamentally used to characterize the intrinsic strength of fibers}.
• It can also be applied to yarns, but yarn strength is also influenced by factors like twist and fiber arrangement, not just fiber material strength.
• Fabric strength is measured by other parameters like tensile strength (force/width), tearing strength, bursting strength.

Answer 1

The Correct Option is A

Tenacity is a term used to describe the strength of a fiber. It refers to the ability of the fiber to withstand stress or force without breaking. In textile terms, tenacity measures the tensile strength of the fiber, which is the amount of force required to break it. It is an important property that determines the durability of fibers in fabrics.

Why Not the Others?

Yarn: While yarn strength is influenced by the tenacity of the individual fibers it is made from, tenacity itself specifically refers to the strength of the fiber, not the yarn.

Fabric: Fabric strength is affected by both the tenacity of the fibers and the way they are woven or knitted together, but tenacity refers to the fiber’s strength, not the entire fabric.

Cotton: Cotton is a type of fiber, so it does not represent the term "tenacity," which refers to strength as a property of fibers in general.

Summary:

Tenacity measures the strength of fiber, specifically how much force the fiber can withstand before breaking, which directly influences the overall strength and durability of textiles made from it.
