Trial #2
To evaluate successful cleaners on cloth substrate
Four products from previous trials were selected to be evaluated for ink removal from cloth substrate. Three products were used at full strength. The fourth was diluted to 20% using DI water in a 600 ml beaker. All four were used at room temperature. Four pieces of cotton cloth were photographed using a Kodak Digital Science DC260 Zoom camera. These pieces were then contaminated in several spots with PolysOne Kennesaw Wiflex MX Mixing Colors -black (85-68-7, 9002-86-2) using a hand held swab. A second photograph was taken. A paper towel was soaked with each cleaner and used to manually wipe the ink from the cloth. A maximum of ten minutes was allowed for cleaning each spot. Final photographs were taken and observations were made.
The three semi-aqueous products had some success, removing most of the ink from the cloth. All cleaners resulted in smearing the ink across the cloth. The figures show pre-soil, soiled and after cleaning of each cloth strip.
Additional testing will be performed to further test the effectiveness of the semi-aqueous products.
