其中KOH处理反应速率最快，能够在10s内达到最佳效果，绒面最大高度差

Among them, the reaction rate of KOH treatment is the fastest, and the best effect can be achieved within 10s. The maximum height difference of the suede, the Pt value of the suede, and the weighted average height of the suede structure are low, but the reaction time needs to be strictly controlled, otherwise it is easy to etch Excessive damage to the inverted pyramid structure. Ultrasonic method is easy to operate and efficient, but the surface modification ability is weak,

Among them, Koh treatment has the fastest reaction rate, which can achieve the best effect within 10s. The maximum height difference of pile, the PT value of pile and the weighted average height of pile structure are all low, but the reaction time needs to be strictly controlled, otherwise it is easy to etch and damage the inverted pyramid structure excessively. The ultrasonic method is easy to operate and efficient, but its surface modification ability is weak,<BR>
