Main properties of tissue paper are absorbency, strength, and softness. Softness can’t be easily quantified to other paper properties such as strength and absorption. Softness can be categorized as bulk and surface softness, bulk softness is the perception when crumpling tissue by hand while surface softness is perception when finger running over the surface of tissue paper. It is reported that softness is a balance between surface smoothness, bulk, and stiffness. Dry strength is a physical property determined by a paper’s ability to maintain the paper web structure and integrity while being used. A sheet’s dry strength is mainly due to fiber-to fiber bonding which typically hydrogen bonding. In this study, dry strength agent was added to pulp stock for manufacturing tissue by different concentration. Furthermore, tissue properties was evaluated based on addition of dry strength agent. |
