How To Understand The Quanta Nonwovens Of Quantitative And Measurement?

Quantitative analysis of non-woven films with film spraying refers to the weight per unit area, usually GM. The number of needled nonwovens is usually limited to 50-100g. Some products with special requirements can reach 3000-5000. Superimposed acupuncture is usually used.

The quantitative measurement of non-woven fabric is usually 100MM or 25, or the sample is taken from a 100MM diameter disc with the number of sampling blocks of 3-10, and the analytical balance is weighed in the laboratory with the precision of 0.01. If product requirements are not high, table balance or electronic balance with accuracy of 0.1g can be used for weighing. The average quantity is calculated according to the weight of several samples. At the same time, the uneven weight ratio is calculated to reflect the uneven weight.

Film spraying is also required to measure the product density of the nonwoven fabric. Its essence and quantity are the same, but the weight per square meter under a fixed thickness is the same. For specific testing, please refer to our measurement of mass per unit area for nonwovens, or ISO spinning - nonwovens test method part I.
