Carpet Density Formula

A carpet s density although many people use density and a related but.

Carpet density formula.

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 face weight and durability. It is expressed in ounces per cubic yard in the formula. Face weight and density are two entirely different components when it comes to evaluating the.

Carpet rule 3. Today we re going to talk about one of those. A high density carpet provides certain advantages compared to a low density carpet. 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.

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. We explain what those are and why they matter. Pile density ratings range from 1000 to 6000 and is determined using a mathematical formula based on the pile height and the fiber face weight. Average pilem density factors for commercial carpets range from 4200 to 8000.

Carpet face weight multiplied by 36 2. To measure carpet density the following formula is used. Pile density is the key to having a carpet retain its like new appearance longer. The longer higher pile the carpet the lower the density rating.

Fiber face weight x 36 divided by pile height in decimal form pile density. The equation isn t important but breaking it down reveals a couple important takeaways about density rating. A higher face weight means more yarn says grable and more yarn makes for a longer lasting product as an example within one product line the good level carpet has a face weight of 40 oz. Here is the formula.

The most important takeaway is density rating eliminates the flaw of face weight. 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. The weight of pile yarn in a unit volume of carpet. Density pile yarn weight in ounces per square yard times 36 divided by pile thickness or pile height in inches.

The best level weighs in at. Divide by carpet pile height 3. To calculate carpet density use the formula of face weight x 36 pile height. The density of a carpet is one of many factors that determine a carpet s quality and overall performance.

In the formula above we represent the pile height as a fraction of. 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. 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.
