Carpet Density Formula

Pile density is the key to having a carpet retain its like new appearance longer.

Carpet density formula.

Equals density measured in ounces per cubic yard fiber height is the length of each carpet fiber from the backing to the tip of the strand itself. Despite a common misconception carpet density and carpet face weight are not interchangeable terms that mean the same thing although face weight is one factor used to calculate density. Carpet rule 3. Here is the formula.

36 density x face weight pile height e g 36 2160 x 30 0 499998 0 5 in this example what we know is that the pile density is 2160 and the face weight is 30 ounces. Divide by carpet pile height 3. We can now use rule 3 to determine the pile height in decimals which can quickly be converted into a fraction of an inch using the chart. Today we re going to talk about one of those.

Face weight and density are two entirely different components when it comes to evaluating the. In the formula above we represent the pile height as a fraction of. The equation isn t important but breaking it down reveals a couple important takeaways about density rating. To measure carpet density the following formula is used.

The longer higher pile the carpet the lower the density rating. Average pilem density factors for commercial carpets range from 4200 to 8000. It is expressed in ounces per cubic yard in the formula. The weight of pile yarn in a unit volume of carpet.

Carpet doesn t have to be dense to be durable as long as it has a high twist level and vice versa. Density pile yarn weight in ounces per square yard times 36 divided by pile thickness or pile height in inches. A high density carpet provides certain advantages compared to a low density carpet. Fiber face weight x 36 divided by pile height in decimal form pile density.

The most important takeaway is density rating eliminates the flaw of face weight. The density of a carpet is one of many factors that determine a carpet s quality and overall performance. In other words if you measure the carpet face weight which is given in ounces multiply it by 36 and divide it by the pile height the height of the carpet fiber measured in fractions of an inch you ll get the density which is given in oz cubic yard. Carpet face weight and durability.

A carpet s density although many people use density and a related but. To calculate carpet density use the formula of face weight x 36 pile height. Carpet face weight multiplied by 36 2. Don t confuse density and twist with face weight which is the amount of fiber measured in ounces per square yard as opposed to total weight which includes the weight of the carpet backing.

We explain what those are and why they matter. The best level weighs in at. The last consideration is face weight weight of the carpet pile per square yard.
