To test the wear and tear of the fabric surface, the following methods can be used:
1. Visual inspection: Initial determination of wear is made by observing changes in the appearance of the fabric surface. The fabric surface can be examined for fading, feathering, stretching, etc., as well as for the appearance of damage or cracks. This method can quickly determine the initial degree of fabric wear.
2. Friction Test: Using a friction test machine or device, the friction of the fabric in daily use can be simulated. During the test, the fabric is rubbed against a standard friction material or other fabrics to test the degree of abrasion resistance and durability. The degree of abrasion of the fabric can be assessed by testing an indicator on the machine or by observing changes in the surface of the fabric.
3. Abrasion Resistance Test: Fabrics are tested for abrasion resistance using a specialized abrasion test apparatus. During the test, the fabric is placed in the test device and subjected to continuous abrasion. The abrasion resistance of the fabric is assessed by measuring the change in weight of the fabric during the abrasion process or by using a specific scoring system.
4. chemical analysis: some chemical methods are used to analyze the abrasion of the fabric surface. For example, scanning electron microscope (SEM) can be used to observe the microstructural changes on the fabric surface, or infrared spectral analyzer (IR) can be used to determine whether the chemical composition of the fabric surface has changed.
5. Mechanical test: evaluate the wear and tear of fabrics by conducting mechanical tests such as tensile or shear. These tests can measure the strength and elongation at break of the fabric when it is subjected to force, and other mechanical performance indexes, so as to indirectly determine the wear of the fabric.
Overall, the testing of fabric surface wear requires comprehensive consideration of several factors, including appearance observation, friction properties, anti-abrasion properties, chemical analysis and mechanical tests. Choosing the right test method can help assess the wear of fabrics and develop corresponding maintenance strategies.
