Illustrations
Illustrations represent the shade of Cartacrom liq. dyes at an aproximate depth of shade of 0,5% dye on dry furnish.
Solubilities are evaluated by gradually adding small amounts of dye to the solution respectively at 80°C (hot solubility) until a significant amount of dye remains undissolved. So table reports the amount of dye in gr that dissolves in 1 liter of water.
Fastnesses
In reference of listed value of fastnesses, they all are obtained at 0,5% dyeing depth. Light fastnesses were estimated using a Xenon arc lamp. Results are evaluated according to the Blue wool scale, where value 8 represents maximum fastness, value 1 minimum one.
Bleed fastnesses are tested in following solutions:- Acid 15 g/l acetic acid
- Alkali 5 g/l sodium carbonate
- Alcool 50%
- Distilled water
Procedure as follows: 2 sheets of Whatman filter paper are wetted with the examined solution, then a sample of paper is placed in between and pressed with a weight of 200 grs at room temperature for 10 minutes.
Then Whatman filter papers are compared with a 1-5 Gray scale. Value 5 represents no coloration, value 1 heavy coloration.
Backwater is collected during the formation of the paper sheet, then value is established with 1-5 Gray Scale. Value 5 represents no coloration, value 1 heavy coloration of backwater.
Bleachabilities. Paper samples are bleached with following method:Method Reductive Oxidative Agent 2% active sodium dithionite (sodium hydrosulphite) 2% active chlorine (calcium Hypochlorite)PH 6 4 Temperature 6°C 50°C Time 60 minutes 60 minutes From the obtained bleached pulp handsheets are produced and then evaluated in terms of residual color strength. To the minimum residual color stength the highest value (5) is assessed, while the minimum (1) is addressed to the highest residual color strength.
