How to calculate the thickness and weight of non-woven fabric?

Any object has a weight, as we said today, there is also non-woven cloth, so how to calculate the weight of non-woven cloth?

4 units are commonly used in gram weight and weight calculation of non-woven fabric.

The second is meter, which is short for m. The third is gram, which is short for gram. The fourth is millimeter, which is short for mm.

The length, The code on norms and meter are computational length, but there is one exquisite here, this concept also is used commonly to distinguish expert and blame the home, because nonwoven cloth is a roll a roll, the height of the roll calls breadth, express with the unit meter, commonly used norms is commonly 2.40 meters,1.60 meters,3.2 meters.

Weight and thickness in grams

Is there a unit of thickness since it has a length and a width?

Yes, yes, grams is used to calculate the thickness of the, g, is refers to the square gram, why didn't the g/m ^ 2 mm?

In fact also useful mm, just use less, this is an industry rules, in fact, square gram weight can be equal to the thickness of mm, because of non-woven fabric grams on 10 g/g / ㎡ to 320 ㎡.

Hardness (feel)/ gloss

At present, the market is rarely about the hardness of non-woven fabric equipment testing, generally by hand feeling/gloss to test.

Tension parameters of nonwoven fabric.

Nonwoven fabric has tension parameters in the longitudinal and transverse direction, if it is formed by irregular drawing, pressing, melting and spraying, the tension in the longitudinal and transverse direction is not different.

Under the gravitational pull of the earth, weight and mass are equivalent, but the units of measurement are different.

A mass of 1 kg is called 1 kg when it is subjected to an external force of 9.8 newtons.

The unit of mass is usually used in place of weight, implicitly multiplied by the acceleration of gravity.

In the old days in China, jin and liang were used as units of weight.

Pounds, ounces, carats, etc are also used as units of weight.

Common units of mass are: microgram (ug), mg (mg), gram (g), kilogram (kg), ton (t), etc.
