What is denier, How to measure a Yarn?

The Denier count is important for manufacturers to make sure their materials are durable enough for the product they are producing.

Many of the textiles are measured using Denier (notated as “##D”, ## being the calculated Denier)

Denier is a unit of measurement that is used to determine the fiber thickness of individual threads or filaments used in the creation of textiles and fabrics. Fabrics with a high denier count tend to be thick, sturdy, and durable. Fabrics with a low denier count tend to be sheer, soft, and silky.

In terms of fills, in order to be considered a “microfiber” the fiber must be less than 1 denier, which is extremely fine. This gives the fill its airy weight, downy feel, and soft, silky texture. In comparison, a human hair is 20 denier, whereas Standard Fiber’s microfibers are typically 0.9 denier or less.

In simpler terms, Denier defines fiber thickness and weight (in grams). While the calculation for denier, 1D=1g/9000m, was originally designed to measure natural fibers such as silk and cotton (hence the silk being the basis of the measurement), it’s most often now attributed to synthetic woven fabrics to boast durability, such as nylon and polyester. The higher the Denier, the more durable your textile will be.
