دستگاه آزمایشی سایش مارتیندیل ASTM-D4966 دستگاه آزمایشی

Introduce
ASTM-D4966 Martindale Abrasion Testing Machine is suitable to the fabric, wool fabric, leather, synthetic leather, etc. at a pressure level of wear resistance and pilling ball experimental

working principle
Circular fabric sample under a certain pressure, and standards such as abrasive by Lisa (Lissajous) curve trajectory friction with each other, resulting in breakage of the specimen to specimen breakdown showing the number of wear-resistant fabric abrasion resistance

ویژگی‌ها

ASTM-D4966 Martindale Abrasion Testing Machine mainly applies to the resistance test of textile and outside layer, lining or underlayer of the footware or the similar fabric. Testing the samples as per the standard, test can be classified as dry test and wet test.  And test the samples Lissajous-oriented for the regulated times, then observe the difference between it and the original samples and decide the grade of scrubbing resistance.
