Anti-drilling and Lint Tester (Impact Method)

• 

The Anti-drilling and Lint Tester (Impact Method) is a specialized piece of equipment designed to assess the resistance of fabrics and materials to snagging, pilling, and linting caused by repeated impact or abrasive forces.

This tester typically operates by subjecting a fabric sample to a controlled series of impacts or slight abrasions from a specific surface or pin. The resulting damage, such as pulled threads (snags), small balls of fiber (pills), or loose fibers (lint), is then evaluated against a standardized scale or visually assessed. This method helps manufacturers determine the durability and appearance retention of textiles, particularly those used in demanding applications like upholstery, activewear, or workwear, ensuring they maintain their quality and aesthetic over time.

Scope of application:

The impact method is used to determine the anti-drilling performance of fabrics, which is suitable for testing various down products, such as down quilts, down jackets, etc.

Product details:

The fabric to be tested is made into a cylindrical bag, filled with feathers, down or a mixture thereof. The sample bag is placed on the inclined plane, and the impact needle fixed on the movable plate reciprocates with the movable plate, while compressing and impacting the sample bag. Repeat the operation until a certain number of impacts are reached and then stop the test.

Test principle:

The test sample is a cylindrical pillow filled with a certain amount of feathers and down. During the test, the sample is pushed along the inclined plane by the bottom impact rod to the top impact plate, and the sample pillow is compressed. After one impact, the sample slides down along the track and returns to its original state. This step is repeated until the set number of impacts is reached. Since the extrusion range of the impact rod is greater than or less than the circumference of the sample pillow, the pillow will be squeezed at different locations. The anti-drilling performance of the sample is evaluated based on the total number of feathers and down that drill out, extend out and fall in the sample after a certain counting cycle.
