What are the characteristics of corduroy and what is the standard?

Corduroy fabric feels elastic and soft, clear and round velvet, soft and even luster, thick and wear-resistant, but it is easy to tear, especially the tear strength along the velvet direction is low.

During the wearing process of the corduroy fabric, its fluff part is in contact with the outside world, especially the elbows, necklines, cuffs, knees and other parts of the clothing are subject to external friction for a long time, and the fluff is easy to fall off.

The American Standard "Test Method for Fluff Retention of Corduroy Fabrics (ASTM D4685-87)" stipulates the rubbing treatment procedure of corduroy fabric samples, and the instruments and methods for evaluating the retention of fluff. But the main problem is that the evaluation of corduroy fluff retention performance level must be carried out by 3 inspectors with reference to the standard, and the subjective factors of the inspectors will affect the accuracy of the evaluation results.
