Let s try an example.
Carpet density in pounds or ounces.
What does carpet density tell you about carpet quality.
We can now use rule 1 to determine the pile density rating.
Judging carpet quality don t use one factor alone as an indicator of a carpet s overall quality.
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.
To measure carpet density the following formula is used.
Carpet doesn t have to be dense to be durable as long as it has a high twist level and vice versa.
The term refers to the weight of the carpet s fibers only not the backing material.
If you buy a carpet with a face weight of 60 ounces and a 1 2 inch pile height you ll multiply 60 x 36 to obtain 2160 and then multiply that by 1 2 or 5 to obtain a carpet density of 1080 ounces in each cubic yard.
In this example what we know is that the face weight is 30 ounces and the pile height is 0 5 one half inch.
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.
In the formula above we represent the pile height as a fraction of.
Carpet face weight is defined as the weight of the carpet pile per square yard of carpet measured in ounces.
Depending on other features of your carpet a lower or higher face weight may be required.
The last consideration is face weight weight of the carpet pile per square yard.
Carpet face weight multiplied by 36 2.
Carpet rule 2.
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.
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.
You want at least a 35 ounce face weight carpet for maximum durability.
Guidelines for face weight.
Density x pile height 36 face weight e g 2160 x 0 50 36 30.
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.
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.
Carpet face weight and durability.
It should not be confused with the carpet s total weight which is the combined weight of the pile plus the backing.
When buying a carpet to use in typical home environments you ll want to see a density value of at least 3 600.
