how to calculate gsm of non woven fabric？
To calculate the GSM (grams per square meter) of a non-woven fabric, you will need a scale and a sample of the fabric. Here’s a step-by-step guide:
1.Cut a representative sample of the non-woven fabric. The sample should be a square or rectangular shape with a known area, such as 10 cm x 10 cm or 20 cm x 20 cm.
2.Weigh the sample using a scale that can measure in grams. Make sure the scale is properly calibrated for accurate measurements.
3.Record the weight of the sample in grams (e.g., 15 grams).
4.Calculate the area of the sample in square meters. If the sample is 10 cm x 10 cm, the area would be 0.1 m x 0.1 m = 0.01 square meters. If the sample is 20 cm x 20 cm, the area would be 0.2 m x 0.2 m = 0.04 square meters.
5.Divide the weight of the sample (in grams) by the area of the sample (in square meters). For example, if the weight is 15 grams and the area is 0.01 square meters, the calculation would be: 15 grams / 0.01 square meters = 1500 GSM.
6.The result of the calculation will give you the GSM value of the non-woven fabric.
It’s important to note that this method provides an approximate GSM value and may not account for variations in thickness or density within the fabric. For more accurate results, it’s recommended to take multiple samples from different areas of the fabric and calculate the average GSM.
