Analysis of flat abrasion resistance test and influencing factors of woven fabrics

As an important wearing performance of textiles, abrasion resistance has a great impact on the wearing function of fabrics and apparel. Therefore, it is one of the important assessment indicators for wearing fabrics, and it has also received more and more attention from the industry. The flat abrasion resistance test of woven fabrics usually uses the Martindale Abrasion Tester for testing experiments. Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. is a manufacturer of textile testing instruments, which can provide various textile testing instruments. Customers in need are welcome to call in time. inquiries. In addition, a large number of experiments by the engineers of the Standard Group have concluded that improving the wear resistance of fabrics has a great effect on improving the wearing function of fabrics and clothing, especially in some special fields such as labor protection clothing, the requirements for the wear resistance of fabrics higher.

The Martindale Abrasion Tester is suitable for testing the abrasion resistance and pilling degree of woven fabrics, knitted fabrics, woolen fabrics, artificial leather, synthetic leather, etc. under pressure, and is used in textile, footwear, clothing and other industries.


Test principle:

1. Under a certain pressure, the circular fabric sample and the standard abrasive rub against each other according to the movement trajectory of the Lissajous curve, resulting in damage to the sample, and the wear resistance of the fabric is represented by the number of times the sample is damaged. .

2. The circular sample and the fabric of the same material are rubbed with a Lissajous graphic motion trajectory under a given pressure, and after reaching the specified number of revolutions, the pilling level of the sample is evaluated.

The main factors affecting the flat wear resistance of woven fabrics are the fabric's fiber raw material, weave, warp and weft density, warp and weft yarn density, fabric thickness and surface density. The correlations derived from the experiments are as follows:

(1) The greater the deformation ability of the fiber material in repeated stretching, the better the wear resistance of the fabric.

(2) For loose fabrics with low warp and weft density, plain weave fabrics have better wear resistance, but for tighter fabrics, under the same other conditions, twill weave fabrics have better wear resistance than plain weave fabrics.

(3) Under the same other conditions, the linear density of the yarn in the fabric, or the warp and weft density of the fabric, or the thickness and surface density of the fabric are positively correlated with the wear resistance of the fabric. The influence of temperature and humidity conditions in the experiment on the test results is mainly manifested in the fiber, that is, the humidity has a significant effect on the abrasion resistance of viscose fiber, has almost no effect on polyester fiber and acrylic fiber, and has a certain effect on nylon fiber.
