How does the weight of non-woven fabrics calculate?
Apr 12, 2017

In the weight of non-woven fabrics and weights calculation, commonly used to 4 units, one is the code, English yard, abbreviation y; two is meters, English meter, abbreviation m, three is grams, English gram, abbreviation gram, four is mm, abbreviation mm.

1. Length

The size of the code and the meter are calculated lengths, but here is a fastidious, this concept is also commonly used to distinguish between experts and non-experts, because non-woven fabrics are a volume of a volume, the height of the volume is called width, in unit meters, commonly used specifications are 2.40 meters, 1.60 meters, 3.2 meters.

II. Weight and thickness

Since there is a long width, does that have a thickness unit? Yes, some, grams is used to calculate the thickness, gram, is the square gram weight, that is, why not g/m^2 mm? In fact, it is also useful to mm, but less, this is an industry rule, in fact, the square weight can be equated with the thickness of millimeters, because the non-woven weight of grams in 10g/㎡ ~320g/㎡.

3, hardness (feel)/gloss

At present, the market is very little about non-woven hardness tester equipment testing, generally feel/gloss to the pro-test.

Fourth, non-woven tensile parameters.

Non-woven fabrics have vertical and horizontal tensile parameters, if the irregular drawing pressure melting into, then the vertical and lateral tensile difference is not small.

In the gravitational force of the Earth, weight and quality are equivalent, but the units of measurement are different. The mass of 1 kilograms substances is called 1 kilograms weight by 9.8 Newton. Commonly used mass units to replace weight, implied by the acceleration of gravity. In the Chinese old use Jin, two as the weight unit. Pounds, ounces, carat, etc. are also as weight units.
