1、 Introduction
1. The Y571 electric friction color fastness tester uses a friction head of standard weight to perform reciprocating linear motion of standard length at a standard frequency. When the set number of times is reached, the motor automatically stops running.
2. Mainly used in industries such as cotton, wool, linen, silk, knitting, printing and dyeing, as a testing instrument for determining the color fastness to dry and wet friction of various fabrics.
