Methods For Testing The Adhesion Of Textile Silicone

There are various methods for testing the adhesion of textile silicone, including the peeling method, shearing method and stretching method. These methods have their own characteristics, and the appropriate test method should be selected according to the actual application scenario and test requirements.
Peeling method:
Principle: Evaluate the adhesion by measuring the maximum force value between the silicone coating or printed pattern and the textile substrate during the peeling process.
Operation: Use a special peeling tester to gradually peel the silicone coating or printed pattern from the textile substrate and record the maximum force value during the peeling process.
Evaluation: Judge the strength of the adhesion according to the magnitude of the maximum force value.
Shearing method:
Principle: Apply shear force between the silicone coating or printed pattern and the textile substrate, and observe its damage to evaluate the adhesion.
Operation: Use a shear tester or similar equipment to apply a shear force perpendicular to the surface of the textile to the silicone coating or printed pattern until it is damaged.
Evaluation: Observe the shape and position of the damaged surface, as well as the required shear force, to evaluate the strength of the adhesion.
Stretching method:
Principle: Evaluate the adhesion by stretching the connecting part of the silicone coating or printed pattern and the textile substrate, and measuring the force value when it breaks.
Operation: Use a tensile tester to fix the silicone coating or printed pattern to one end of the textile substrate and apply tension to the other end until it breaks.
Evaluation: The strength of the adhesion is determined by the force at break.
