AATCC Electronic Crockmeter mainly consists of the control system and friction system, fix sample by sample holder on the end of the base sticking a sandpaper, put abrasion head with a white cotton cloth on the sample. After rubbing the fixed number of times, observe sample and evaluate the coloring degree of white cotton cloth comparing with gray card, make judgments to the stain of the fabric sample or the stability of surface coating provide reference data for the assessment and selection of materials.
Rubbing fastnes Tester Crockmeter uses dry or wet white cotton cloth to tie the surface of the friction hammer of the machine. According to the specified method, with a certain load and number of times, the sample and the white cotton cloth for friction are rubbed against each other, and the degree of staining of the white cotton cloth for friction is equal to Staining rating gray scale for comparison, and assessing the color fastness to rubbing
Manual AATCC Rotary Vertical Crockmeter is mainly used to test the color fastness changes of textile, printing and dyeing, printing and other products after circular track rubbing.
AATCC Electronic Crockmeter is suitable for testing the color fastness to rubbing and staining of all kinds of textiles (made of various fibers, dyed or printed yarns, fabrics and textile products, including textile carpets and other velvet fabrics).
Rotary Vertical Crockmeter(Electronic) is used to determine the color fastness of textiles under dry or wet friction. It is mainly used to measure the color fastness changes of textile, dyeing, printing and other products after friction with a specific track.
