How to calculate the weight of non woven fabric?

Weight is a basic property of an object. Any object has weight. non woven fabric also has its weight. But many people will wonder how the weight of the non woven fabric is calculated. As Synwin non woven fabric supplier takes a look at the way to calculate the weight of non woven fabric.


Calculation of weight of non woven fabric


In the calculation of gram weight and weight of non-woven cloth, four units are commonly used. Meter (m), gram (g), gram (g), and mm (mm).


The length of the 1.


In the specification of yards and meters are calculated length, but there is a particular, the concept is often used to distinguish between experts and non-bankers, because the non-woven cloth is a roll of a roll, the height of the roll is called width, expressed in units of meters, commonly used specifications are generally 2.40 meters,1.60 meters,3.2 meters.


2. Gram weight and thickness


Since there is a length and a width, is there a thickness unit? Yes, there is, the grams are used to calculate the thickness, grams, which means the square gram weight, which is g/m^2, why not millimeters? In fact, it is also useful to use mm, but less, which is an industry rule, in fact, the square gram weight can be equal to the thickness of mm, due to the non-woven cloth in the gram weight of 10g/ m2 ~320g/ m2.


3. Hardness (feel)/ luster


At present, there are few non-woven cloth hardness instruments and equipment testing in the market.


4. Tension parameters of non woven fabrics.


non woven fabric has vertical and horizontal tension parameters, if it is irregular wire drawing pressure fusion spray, the vertical and horizontal tension difference is not big.


Under gravity, weight and mass are equal, but the units of measurement are different. The weight of a material with a mass of 1 kg when subjected to an external force of 9.8 newtons is called 1 kg. The unit of mass is usually used in place of weight, implicitly multiplied by the acceleration of gravity.


How to identify non woven fabric by hand feeling visual measurement:


This method is suitable for non - woven materials in loose fiber state.


(1) cotton fiber is shorter and thinner than ramie fiber and other hemp processing fiber and wool fiber, often with a variety of impurities and defects.


(2) hemp fiber feels rough and hard.


(3) wool fiber is curly and elastic.


(4) silk is a filament, long and slender, with a special luster.


(5) among the chemical fibers, only viscose fiber has a great difference in strength in the dry and wet states.


(6) spandex yarn has great elasticity, and its length can be stretched to more than five times at room temperature.
