Abrasion resistance test and influencing factors of woven fabrics

As an important performance of textile, abrasion resistance has a great influence on the function of fabric apparel, so it is one of the important assessment indexes of fabric, and has been paid more and more attention by the industry. Ltd. is a textile testing instrument manufacturer, can provide a variety of textile testing instruments, welcome customers with demand for timely telephone inquiries. In addition, the standard group engineers a large number of experiments, improve the abrasion resistance of the fabric to improve the fabric clothing taking function has a great role in promoting, especially in some special areas such as labor fang care clothing field, the requirements of the fabric abrasion resistance is higher.

 

Martindale abrasion resistance instrument for woven fabrics, knitted fabrics, woolen textiles, artificial leather, synthetic leather, etc. in the pressure of abrasion resistance and pilling degree test, applied to a variety of industries such as textiles, footwear, clothing.

 

Test principle.

 

1. Round fabric specimens under a certain pressure, and standard abrasives according to Lissajous (Lissajous) curve of the trajectory of mutual friction, resulting in specimens broken, the number of broken specimens wear resistance to express the wear resistance of the fabric.

 

2. Round specimen and the same material fabric under a given pressure, to Lissajous graphical motion trajectory for friction, to reach the specified number of revolutions, the evaluation of the specimen pilling grade.

For different fiber raw materials fabric, wool woven fabric wear resistance is good, viscose woven fabric wear resistance is poor, polyester/cotton blend woven fabric wear resistance in the middle. This is consistent with the deformation capacity of fiber raw materials in repeated stretching, the abrasion resistance of the fabric is good. Fiber deformation capacity in repeated stretching is determined by the strength, elongation and elasticity of the fiber. Therefore, although the strength of wool fiber is not high, but its elongation and elasticity is large, and the fracture work after repeated stretching is reduced less, and the abrasion resistance of its fabric is better. Although the strength of viscose fiber is high, but its elasticity is poor, and the work of breaking after several stretches decreases significantly, so the abrasion resistance of its fabric is poor. Polyester fiber fracture work is large, elastic recovery ability is high, and cotton blend after these properties have decreased, but the wear resistance of its blended fabrics is still quite good.

 

The factors affecting the abrasion resistance of woven fabrics are mainly the fiber raw material of the fabric, organization, warp and weft density, warp and weft yarn density, fabric thickness and surface density. The correlation derived from the experiment is as follows.

 

(1) The greater the deformation capacity of the fiber raw material in repeated stretching, the better the abrasion resistance of its fabric.

 

(2) For loose fabrics with low warp and weft densities, the abrasion resistance of plain tissue fabrics is better, but for tighter fabrics, the abrasion resistance of twill tissue fabrics is better than that of plain tissue under the same other conditions.

 

(3) Under the same conditions, the linear density of the yarn in the fabric, or the fabric warp and weft density, or the fabric thickness and surface density are positively correlated with the abrasion resistance of the fabric. The influence of the temperature and humidity conditions on the test results was mainly on the fibers, i.e., humidity had a significant effect on the abrasion resistance of viscose fibers, almost no effect on polyester and acrylic fibers, and some effect on nylon fibers.

 

The above is Standard International Group (HK) for customers to introduce the fabric abrasion resistance test related details, hope to help users, of course, if you want to buy products welcome you to come to consult.
