Water absorption in carboxymethyl cellulose

Boruvkova K., Wiener J.

Autex Research Journal

2011

Vol. 11, no. 4

110--113

The paper deals with the testing of carboxymethyl cellulose properties. It was verified whether carboxymethyl cellulose soaked in water, salt solution or pH adjusted water resulted in better sorption properties than 100% cellulose represented by standardised cotton fabric. During the measurements the samples were dipped into water of different temperatures (10°C, 20°C, 30°C, 40°C, 50°C), in a NaCl solution (concentration 0.1g/l, 0.9 g/l, 5 g/l and 10 g/l) and in water with a modified pH (5, 7, 9). Another measure was aimed at monitoring changes in the structure of the textile samples soaked in water at a temperature of 20°C with subsequent drying, which was carried out using an electron microscope.
