微小摩擦力测试仪的PWM电机调速。
The third is micro friction surveyor's apparatus' PWM electronic machinery test.
等离子体整理后纤维表面产生微小的细纹和凹坑，使纤维之间的摩擦力增加，减小织物的强力损失。
After the plasma finishing, the fabric surface had fine lines and pits, and the friction between the fibers was increased, which could effectively improve the fabric strength losses.
