What is the thickness and weight of the non-woven fabric?
Release date:2019-03-19
Any object is weighty. Just like the non-woven fabric we have today, how is the weight of the non-woven fabric calculated?
In the weight and weight calculation of non-woven fabrics, 4 units are commonly used, one is the code, the English yard, referred to as Y; the second is the meter, the English meter, referred to as m, the third is the gram, the English gram, referred to as the gram, the fourth is Mm, referred to as mm.
Non-woven fabric
First, the length
In the standard, the code and the meter are both accounting lengths, but there is a particularity here. This concept is also used to distinguish between experts and non-experts, because the non-woven fabrics are all one roll, the height of the roll is called width, and the meter is used. It shows that the commonly used standard is generally 2.40 meters, 1.60 meters, 3.2 meters.
2. Weight and thickness
There are already length and width, is there a thickness unit? Yes, some, the gram is used to calculate the thickness, gram, refers to the square gram weight, that is, why does g/m^2 not use millimeters? In fact, there are In millimeters, it is only used less. This is an industry rule. In fact, the square gram weight can be equal to the millimeter in thickness because the gram weight of the nonwoven fabric is between 10g/m2 and 320g/m2.
Third, hardness (feel) / gloss
At present, there are very few tests on non-woven hardness equipment in the market, which are generally measured by hand/gloss.
Fourth, the tensile parameters of the non-woven fabric.
The non-woven fabric has longitudinal and transverse tensile parameters. If it is irregularly drawn and melt-blown, the longitudinal and transverse tensile forces are not much different.
Under the gravity of the Earth, the components and mass are equivalent, but the units of measurement are different. A mass of 1 kg of material is subjected to an external force of 9.8 cattle and is called a kilogram weight. The mass unit is usually used instead of the component, which is implicitly multiplied by the acceleration of gravity. In the old days of China, Jin and two were used as weight units. Pounds, ounces, carats, etc. are also used as component units.
Commonly used quality units are: micrograms (ug), milligrams (mg), grams (g), kilograms (kg), tons (t), and the like.
