How is the lining tested for peel strength?

1. Test Methods
（1）Sampling: Cut the sample from the interlining to be tested in the specified size and direction. The sample should be large enough to be able to fully demonstrate its adhesive properties during the test.
（2） Pre-treatment: According to the requirements of the test standard, the sample is pre-treated, such as moisture treatment, washing treatment, etc., in order to simulate the actual use conditions.
（3）Testing process: Clamp the sample on the peel strength tester, set the appropriate peeling speed, peeling angle and peeling length and other parameters. Then start the tester so that the sample is peeled off at a constant speed.
（4）Data Recording and Analysis: Record the maximum peeling force during the peeling process and calculate the average value or other statistical indexes according to the requirements of the test standard. Analyze the test results to assess whether the peeling strength of the interlining meets the expectation.shenghong interlining factory china

2. The test instrument and equipment
Peel strength test requires the use of professional peel strength tester. These instruments are usually characterized by high precision and automation, can accurately measure the maximum peeling force in the peeling process, and automatically record and analyze the data. Common peeling strength testers include electronic peeling strength tester and mechanical peeling strength tester.

3.Influencing factors and precautions
（1）Influencing factors
The material of the lining, thickness and type of adhesive and other factors will affect the peel strength test results. Therefore, the consistency of the test conditions should be ensured when conducting the test in order to accurately assess the adhesive properties of different interlining fabrics.
Environmental conditions (e.g. temperature, humidity, etc.) during testing may also have an effect on peel strength. Therefore, the environmental conditions should be strictly controlled before testing to ensure the accuracy of the test results.
（2）Precautions
In the process of sampling and pretreatment, the operation should be carried out in strict accordance with the requirements of the test standards to avoid adverse effects on the test results. During the testing process, the operational status of the tester and the changes in the test results should be closely monitored, and the data should be recorded and analyzed in a timely manner. For the test results do not meet the expected situation, should be reviewed and analyzed to find out the possible reasons and take corresponding measures for improvement.china shenghong interlining manufacturer
 

Peel strength test has a wide range of applications in garment and textile manufacturing. Through the test, manufacturers can understand the bonding performance of interlinings, optimize production processes and formulations, and improve the overall quality and durability of their products. At the same time, the test helps consumers make more informed decisions when choosing apparel and textiles, ensuring that the products they buy have excellent bonding and durability.
