How To Calculate Gsm Of Non Woven Fabric
Jul 08, 2024
Calculating the GSM (grams per square meter) of non-woven fabric involves a straightforward process. Here's how you can do it:
Materials Needed:
A sample of the non-woven fabric
A weighing scale (preferably digital for accuracy)
A ruler or measuring tape
Scissors (if you need to cut the fabric sample)
Steps:
Cut a Sample:
Cut a rectangular or square piece of the non-woven fabric. The sample size can be any convenient size, but common dimensions are 10 cm x 10 cm or 20 cm x 20 cm. Let's assume you cut a 10 cm x 10 cm sample.
Measure the Sample Area:
Calculate the area of your fabric sample. For a 10 cm x 10 cm sample, the area is: Area=10 cm×10 cm=100 cm2\text{Area} = 10 \text{ cm} \times 10 \text{ cm} = 100 \text{ cm}^2Area=10 cm×10 cm=100 cm2
Weigh the Sample:
Use the digital weighing scale to measure the weight of the fabric sample. Make sure the scale is calibrated and the sample is clean and dry. Let's say the weight of the sample is 1.5 grams.
Convert the Area to Square Meters:
Convert the area from square centimeters to square meters: 100 cm2=0.01 m2100 \text{ cm}^2 = 0.01 \text{ m}^2100 cm2=0.01 m2 (since 1 m² = 10,000 cm²)
Calculate the GSM:
Use the weight and the area to calculate the GSM: GSM=Weight of the sample (grams)Area of the sample (square meters)\text{GSM} = \frac{\text{Weight of the sample (grams)}}{\text{Area of the sample (square meters)}}GSM=Area of the sample (square meters)Weight of the sample (grams) For our example: GSM=1.5 grams0.01 m2=150 grams/m2\text{GSM} = \frac{1.5 \text{ grams}}{0.01 \text{ m}^2} = 150 \text{ grams/m}^2GSM=0.01 m21.5 grams=150 grams/m2
Example:
If you cut a 10 cm x 10 cm sample and it weighs 1.5 grams:
The area of the sample is 0.01 m².
The weight of the sample is 1.5 grams.
Therefore, the GSM is: GSM=1.5 grams0.01 m2=150 grams/m2\text{GSM} = \frac{1.5 \text{ grams}}{0.01 \text{ m}^2} = 150 \text{ grams/m}^2GSM=0.01 m21.5 grams=150 grams/m2
This method can be used for any sample size as long as you measure the area and weight accurately and convert the area to square meters correctly.
