## How do you calculate yarn percentage?

Fabric Production Calculation

1. Loom Speed = Motor RPM * (Motor Pully Diametre)/(Loom Pully Diametre)
2. Loom Effeciency Percentage = (Actual Production/Calculated Production )* 100.
3. Moisture Regain Percentage = {(Yarn Weight – Dried Yarn Weight)/Dried Yarn weight} * 100.

## What is yarn consumption?

To produce a particular woven fabric of particular fabric specification, yarn consumption can be theoretically calculated. The process of yarn consumption calculation of a particular woven fabric is explained with the help of an example.

## How do you calculate yarn denier?

You can, however, calculate the deniers of a sample from its standard density, measured in grams per cubic centimeter. Divide the result by 4 x 10^-6, a constant conversion factor: 0.004972 / (4 x 10^-6) = 1,243. This is the yarn’s density in deniers.

## How do you calculate fabric usage?

Figure out how much fabric you need with this formula:

1. Width of fabric divided by width of one piece equals the number of pieces that fit into width (rounded down to the whole number).
2. Total number of pieces divided by number of pieces that fit into width equals number of rows you need.

## How is GSM calculated?

Convert fabric weight into grams per square meter. To calculate it multiply above weight by 100. This will be GSM of the fabric. For accuracy test with multiple (e.g. 5 samples) samples and calculate average GSM.
