| Abstract | Environmental concerns are driving the effort to find new methods for producing many common items from renewable and biodegradable resources. In particular, it has an effect on the development of the wood fiber based product. A foam forming method was found as a new method for producing a specific and unique paper properties. The purpose of this study is to investigate characteristics of the fiber foam forming product. The product was made from Spruce Pine Fir (SPF) pulp and Eucalyptus pulp. Anionic, amphoteric and nonionic surfactants were used as a foaming agent.The effect of surfactant type, pulp resources , beating/refining and chemical additives was observed. The air content of the fiber foam forming product furnish was varied from 0 % to more than 50 %. The result indicates that air content in the paper furnish has a great effect on the properties of the final product.The increasing of air content in the stock would increase the bulk and porosity property of the fiber foam forming product, whereas tensile strength was reduced. It also was found that surfactant type have not a significant effect on the final product properties. Difference pulps sources given a different characteristic of the fiber foam forming product. Longer fiber produces higher bulk and porosity but lower tensile strength compare with short fiber. Mechanical pulp has higher tensile strength compare with chemical pulp. Refining/beating improve tensile strength of the fiber foam forming product significantly, especially for longer fiber. Cationic starch also improves tensile strength of the fiber foam forming product even not so significant as refining or beating process. Cationic starch was ineffective used together with anionic surfactant. With higher bulk and better formation, the fiber foam forming product has a large potential for hygiene and packaging industries |
