Fabric abrasion and pilling is one of the most important factors affecting its appearance and performance. The following is an assessment report on fabric abrasion and pilling:

Abrasion Assessment:

1. Martindale Abrasion Test: This test uses a Martindale abrasion tester to rub a standard-sized abrasion head against a fabric a certain number of times to simulate extended periods of actual use. The shape and texture of the abrasion head allows different types of fabrics to be tested. 2.

2. Wyzenbeek Abrasion Test: This test utilizes a Wyzenbeek Abrasion Tester, where a knitted or dense fabric is impaled on a standard-sized cylinder and rubbed through the fabric under pressure to simulate extended periods of actual use.

Pilling Evaluation:

1. Pill Box Pilling Test: This test involves placing a sample in a Pill Box and subjecting it to a rotational rolling and scratching test for a standard period of time. The fabric is then visually evaluated using specialized instruments to determine the degree of wear and tear and pilling.

2. Martindale Pilling Test: This test uses the pilling test head of the Martindale Abrasion Tester, which is rubbed a certain number of times and the fabric is then visually evaluated using specialized instruments to determine the degree of pilling.

Typically, the following aspects are included in the abrasion and pilling assessment report:

1. Abrasion rating: Depending on the results of the abrasion test, fabrics may be categorized into different abrasion ratings, such as mild, moderate and severe abrasion ratings. These ratings help consumers understand the life and durability of the fabric.

2. Pilling ratings: Depending on the results of pilling tests, fabrics may be categorized into different pilling ratings, such as no pilling, light pilling, moderate pilling and severe pilling ratings. The pilling level assesses the smoothness and neatness of the fabric surface. 3.

3. Visual Assessment: Abrasion and pilling test results are often evaluated using numerical, graphical, or descriptive language to assess the appearance of the fabric. These assessments can describe aspects such as the degree of damage, color change, fiber exposure, pilling size and density of the fabric.

In addition to wear and pilling assessments, fabric quality test reports may include other aspects such as:

4. tensile properties: results of tensile testing of fabrics, including maximum tensile force, elongation at break, etc., used to assess the strength and elasticity of the fabric.

5. thickness and weight: measurement of the thickness and weight of the fabric to assess the uniformity of its density and thickness, which can also be used as a reference indicator of quality.

6. Wrinkle resistance: Evaluating the wrinkle resistance of fabrics, including crease recovery angle, etc., which is used to judge the wrinkle resistance of fabrics.

These tests and evaluation reports can help manufacturers understand the performance characteristics of fabrics, help consumers make more informed purchasing decisions, and provide designers and brands with guidance on product development and improvement.
