In our daily life, facial tissues are one of the indispensable supplies. An important indicator of the quality of facial tissues is softness. So, how to test the softness of facial tissues scientifically? This requires the help of a professional tissue softness tester. Today, let's take a look at how this tester works and how it can help us judge the quality of facial tissues.
First, let's understand what softness is. Under specified conditions, when the plate probe of the softness meter presses the specimen into the crack to a certain depth (about 8mm), the sum of the bending resistance of the specimen itself and the friction force between the specimen and the gap is called the softness, which is expressed in millinewtons. In simple terms, the lower the softness value, the softer the specimen.
The tissue softness tester is designed based on this principle. It ensures the accuracy and reliability of test results by precisely controlling test conditions such as temperature, humidity, pressure, etc. During the test, the instrument places a sample of facial tissue into the slit and then applies a certain amount of pressure. In this case, the bending resistance of the specimen itself and the friction with the crack are measured and recorded. The vector sum of these forces is what we call the softness value.
So, how do you interpret the softness test results? Generally speaking, the lower the softness value, the softer the texture and the more comfortable it is to use. That's because soft facial tissues fit better**, reducing friction and irritation, making it more natural and comfortable to use. Therefore, when choosing facial tissues, we can refer to the softness test results and choose those with smaller softness values.
In conclusion, the facial tissue softness tester provides us with a scientific way to evaluate the quality of facial tissues. By understanding the principles and methods of softness testing, we can better choose the right facial tissue products for ourselves and improve the comfort of life. Hopefully, this article has given you a deeper understanding of facial tissue softness testers.
