What is a non-woven fabric tensile strength testing machine?
In today's industrial production and material testing fields, the non-woven tensile strength testing machine is an important equipment widely used to test the mechanical properties of non-woven materials. As non-woven fabrics are increasingly used in medical, environmental protection, packaging and other industries, the quality requirements for them are also getting higher and higher. This article will introduce in detail the definition, working principle, application scenarios and related technical parameters of the non-woven tensile strength testing machine.
1. Definition of non-woven tensile strength testing machine
The non-woven tensile strength testing machine is an instrument specially used to test the mechanical properties such as strength, elongation, and breaking strength of non-woven materials in the tensile state. It evaluates the quality and durability of non-woven fabrics by simulating the tensile forces they may be subjected to in actual use.
2. Working principle
The working principle of the non-woven tensile strength testing machine is to fix the non-woven fabric sample through a clamp, then apply tensile force through a motor or hydraulic system, and record the force value changes and deformation of the sample during the stretching process. Test data can be displayed and saved in real time for subsequent analysis.
| test items | Test method | unit |
|---|---|---|
| tensile strength | GB/T 3923.1-2013 | N/5cm |
| Elongation at break | GB/T 3923.1-2013 | % |
| Tear strength | GB/T 3917.3-2009 | N |
3. Application scenarios
Non-woven fabric tensile strength testing machine is widely used in the following fields:
1.Medical industry: Used to test the tensile properties of medical non-woven masks, protective clothing and other products to ensure that they are not easy to break during use.
2.Environmental protection industry: Used to test the durability of non-woven products such as environmentally friendly bags and filter materials.
3.Packaging industry: Used to evaluate the tensile strength of packaging materials to ensure they will not be damaged during transportation.
4. Technical parameters
