Have you ever seen the label denier (D) when purchasing clothes or stockings?
One of the most important points that many buyers consider before purchasing fabric is denier.
What is Deneier?
Denier is a unit that represents the thickness of fiber or thread.
When ‘a fiber 9,000 meters long weighs 1 gram’, it is written as ‘1 denier’.
10D = Thickness of thread when 9,000m of thread weighs 10g
The larger the denier value, the thicker the fiber, and the smaller the value, the thinner the fiber.
Then why?
why vaguely set the standard at 9,000m rather than 10,000m?
Before we know that, let’s first learn about the etymology of denier.
The etymology of 'denier'
Denier was originally a unit of currency.
The French "denier" comes from the Latin "denarius";
This Latin word comes from "ten" (10) and originally meant "ten" small coins.
Then, as the textile industry developed in Europe in the late 19th and early 20th centuries, denier began to be used as a fiber unit in France.
As the industry developed, they need for more precise measurement of thread thickness arose, and the unit called "denier" began to be used to express the thickness of the fiber.
In other words, denier was originally a unit that meant small and low value.
Over time, it was used as a unit to indicate the thickness of the fiber.
It came to be used to mean a relatively light thread.
Why 9,000m?
The exact historical background as to why 1 denier was defined as 9,000 meters is not clear, but it appears to have originated from the technological needs of the time.
It is also related to the kilometer (km) as a unit of length and may have been a relatively simple and intuitive measure of fabric or thread at the time.
Denier notation on 'fiber'
denier notation is used not only for ‘clothing’ and ‘fabric’ but also for things such as ‘chemical cotton’.
Monofilament is a fiber made up of only one thread, unlike fabric made by twisting several strands of thread. These short fibers are thin and strong and are used in a variety of industries.
Now do you know the definition and origin of 'denier'?
Don't forget that denier is used to express the thickness of fiber!
