What does carpet density tell you about carpet quality.
Carpet density in pounds or ounces.
Carpet doesn t have to be dense to be durable as long as it has a high twist level and vice versa.
To measure carpet density the following formula is used.
We can now use rule 1 to determine the pile density rating.
The term refers to the weight of the carpet s fibers only not the backing material.
In this example what we know is that the face weight is 30 ounces and the pile height is 0 5 one half inch.
You want at least a 35 ounce face weight carpet for maximum durability.
Density x pile height 36 face weight e g 2160 x 0 50 36 30.
Divide by carpet pile height 3.
Judging carpet quality don t use one factor alone as an indicator of a carpet s overall quality.
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.
For example a carpet with a 50 ounce face weight and a pile height of 1 2 an inch would have a density of 3 600 ounces per cubic yard 50 x 36 0 5 3 600.
Factors that may affect the minimum face weight needed are how often the room is used the carpet s twist level and the carpet s density.
As an example if you take carpet with a 60 oz face weight and a 75 inch pile height it s density will be 2 880 ounces per cubic yard 60 x 36 75 2880.
When buying a carpet to use in typical home environments you ll want to see a density value of at least 3 600.
Carpet face weight and durability.
Guidelines for face weight.
The best level weighs in at.
Let s try an example.
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.
Carpet face weight multiplied by 36 2.
What is a minimum carpet density value to look for when buying a carpet.
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.
Depending on other features of your carpet a lower or higher face weight may be required.
Carpet face weight is defined as the weight of the carpet pile per square yard of carpet measured in ounces.
Carpet rule 2.
In the formula above we represent the pile height as a fraction of.
