The greatest longitudinal stress a substance can bear without tearing asunder, -- usually expressed with reference to a unit area of the cross section of the substance, as the number of pounds per square inch, or kilograms per square centimeter, necessary to produce rupture.
The relative strength of a thread, calculated by dividing the tensile strength by the thickness of the thread.
A term relating to the strength per size of a thread and is generally measured in grams per denier. The following fibers are ranked according to their tenacity from strongest to weakest: Kevlar® Nylon, Polyester, Nomex®, Lyocell®, Rayon, CS Cotton, CP Cotton. Threads made from continuous filament fibers are stronger and have a higher tenacity than threads made from staple fibers.
The reaction of a mineral to certain stress.
patience, grit, toughness, strength, nerve.
The breaking strength of a yarn or fabric stated in force per unit of the cross-sectional area.
The term generally used in yarn manufacture and textile engineering to denote the strength of a yarn or of a filament of a given size. Numerically it is the grams of breaking force per denier unit of yarn or filament size; grams per denier, gpd. The yarn is usually pulled at the rate of 12 inches per minute. Tenacity equals breaking strength (grams) divided by denier.
A unit used to measure the strength of a fibre or yarn, usually calculated by dividing the breaking force by the linear density.
The tensile stress at rupture of a fiber expressed in grams of force per denier. Tenacity relates to the breaking strength of fibers and should not be confused with modulus, which relates more directly with a fiber's ability to resist stretch.
