Detailed explanation of the main methods and applications of fabric hardness tes

 

Compression testing

Principle: Place the fabric sample on the testing platform and apply a predetermined pressure. Measure the degree of compression of fabric under pressure.

Equipment: Compression hardness testers are commonly used, which can accurately measure the deformation of fabrics under pressure.

Application: Used to evaluate the softness and comfort of filling materials such as mattresses and seat cushions.

 

Principle: Measure the stiffness of fabric when bent. Usually, the fabric sample is hung on a tester and then subjected to bending force to measure its degree of bending.

 

Application: Used to evaluate the drape and feel of fabrics, such as the softness of clothing fabrics.

 

Principle: Test the hardness of fabrics during tearing or peeling processes. Measure the resistance of a fabric by applying tension.

 

Application: Used to evaluate the wear resistance and strength of fabrics, commonly used in testing packaging materials and wear-resistant fabrics.

 

Principle: Measure the ability of a fabric to return to its original state after compression. Can the fabric quickly return to its original form after removing pressure.

 

Application: Used to evaluate the elasticity and form retention ability of fabrics, such as testing sportswear and elastic fabrics.

 

ISO standards: The International Organization for Standardization (ISO) provides various textile testing standards, such as ISO9073 (Physical Property Testing of Textiles).

ASTM standard: The American Society for Testing and Materials (ASTM) also provides relevant fabric hardness testing methods, such as ASTM D1388 (fabric softness and stiffness testing).

 

Clothing manufacturing, hardness testing is used to ensure the softness of fabrics is suitable for different seasons and uses. For example, winter jackets require harder fabrics to maintain their shape, while summer shirts require softer fabrics to increase comfort.

Household items, testing the hardness of filling materials such as mattresses and sofa cushions to ensure their comfort and durability. Materials with moderate softness and hardness can provide better support and comfort.

In the automotive industry, testing the hardness of car seats and interior materials to improve driving comfort and safety. Ensure consistent performance of materials over long-term use.

 

In the packaging industry, evaluate the hardness and durability of packaging materials to ensure that they can effectively protect products and reduce damage during transportation.
