Abstract
Effects of temperature of the tetraethylammonium hydroxide (TEAH)/urea/cellulose solution on viscosity, surface tension, and size of cellulose beads were investigated. Hardwood bleached kraft pulp (HwBKP) was used as a cellulose sauce and the dropping method was utilized to fabricate cellulose beads. Temperature of cellulose solution was varied from 30℃ to 50℃. When the temperature of cellulose solution was increased, the viscosity decreased while the surface tension increased. In addition, increasing the temperature of cellulose solution resulted in the increased size of cellulose beads possibly due to the increased surface tension.
