How to calculate the thickness of non-woven fabric?

How to calculate the thickness of non-woven fabric? Thickness, air permeability and tensile strength are important basis for non-woven fabric quality testing and judgment standards. Different types of non-woven fabric products have different thicknesses, so the thickness standard of non-woven fabrics is general They are all based on customer requirements and actual needs.　　The weight of general non-woven fabrics is calculated according to g/m2, which is the weight of a square non-woven fabric. It is not closely related to the thickness. 200g/m2 products can achieve various thicknesses.　　 The weight and thickness of non-woven fabric. Since there are length and width, is there a unit of thickness? Yes, yes, gram is used to calculate the thickness, gram refers to the square gram weight, that is, g/m^2, why not millimeters? In fact, it is also useful Millimeters are just used less. This is an industry rule. In fact, the square grammage can be equivalent to the millimeters of the thickness, because the grammage of non-woven fabrics is between 10g/㎡~320g/㎡.　　Non-woven fabrics are generally not calculated according to the thickness, and they are sold by weighing. Although the specifications of various non-woven fabrics are different, these have little effect on the price of non-woven fabrics. Generally, a special weight gauge is used to measure the weight of non-woven fabrics. If there is no one, the weight will be weighed by 1 square meter. The grammage of the non-woven fabric is deviated, and the standard is only measured several times. How is the thickness of the non-woven fabric calculated? The thickness of the non-woven fabric is not arbitrarily determined. Its thickness is determined according to different processing techniques, different production conditions and different requirements of customers. According to the regulations in the non-woven fabric industry, it is necessary to ensure For the quality and performance of non-woven fabrics, non-woven fabrics must reach a certain thickness, and the air permeability and tensile strength of non-woven fabrics must meet the specified requirements!
