Anti aging principle of non-woven fabrics
Non woven fabrics are affected by many factors during use, such as ultraviolet radiation, oxidation, heat, moisture, etc. These factors can lead to a gradual decline in the performance of non-woven fabrics, thereby affecting their service life. The anti-aging ability of non-woven fabrics is an important index to evaluate its service life, which usually refers to the degree of performance change of non-woven fabrics after being affected by natural environment and artificial environment within a certain period of time.
Test method for aging resistance of non-woven fabrics
（1） Laboratory testing
Laboratory tests can simulate the use process of non-woven fabrics in different environments, and evaluate the anti-aging performance of non-woven fabrics through experiments under laboratory conditions. The specific operation steps are as follows:
1. Choose laboratory environment: Build a suitable environment simulator in the laboratory to simulate the use of non-woven fabrics in different environments.
2. Choose a testing method: Based on the testing purpose and needs, select a suitable testing method, such as light aging test, oxygen aging test, wet heat aging test, etc.
3. Preparation before testing: Prepare the non-woven fabric, including sampling, preparation, etc.
4. Testing: Place the sampled non-woven fabric into a laboratory environment simulator and conduct testing according to the selected testing method. The test time should be long enough to fully evaluate the anti-aging performance of non-woven fabrics.
5. Analysis and judgment of test results: according to the test data, analyze and judge to obtain the anti-aging performance of non-woven fabrics.
（2） Actual usage testing
The actual use test is to evaluate the anti-aging performance of non-woven fabrics by putting them into the actual use environment for long-term observation and monitoring. The specific operation steps are as follows:
1. Choose usage environment: Choose a suitable usage environment, such as indoor or outdoor, different regions, different seasons, etc.
2. Develop a testing plan: Based on the testing objectives and needs, develop a testing plan, including testing time, testing methods, etc.
3. Preparation before testing: Prepare the non-woven fabric, including sampling, preparation, etc.
4. Usage: Place the sampled non-woven fabric into the usage environment and use it according to the testing plan.
5. Analysis and judgment of test results: according to the actual use, analyze and judge to obtain the anti-aging performance of non-woven fabrics.
Attentions and skills in anti-aging test of non-woven fabrics
1. Choose appropriate testing methods and environments.
2. Develop a complete testing plan, including testing time, testing methods, etc.
3. In order to reduce testing errors, sampling and sample preparation should follow standards and avoid the influence of human factors as much as possible.
During the testing process, it is necessary to regularly monitor and record relevant data for subsequent analysis and judgment.
After the test is completed, the test results should be analyzed and judged, conclusions should be drawn, and the test results should be archived and saved.
Conclusion
The anti-aging ability of non-woven fabric is an important index to ensure its service life. In order to evaluate the anti-aging performance of non-woven fabrics, laboratory tests and practical use tests can be conducted. During the testing process, it is necessary to pay attention to the selection of testing methods and environments, develop a complete testing plan, follow standards when sampling and preparing samples, and try to avoid the influence of human factors as much as possible. After the test is completed, it is necessary to analyze and judge the test results, and archive and save the test results.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
