Abstract

SURFACE SIZING of paper by ANIONIC STARCH was carried out to study its concentration effect on PHYSICAL AND STRENGTH PROPERTIES of recycled paper. For this, hand sheets (100 GSM) of mixed recycled pulp containing 1% cationic starch were prepared and treated by the sizing agent on the sheet surface at various concentrations (0, 3-10%). Application and concentration increment of the starch solution resulted in a higher retention on the surface and lesser penetration into the paper structure (Z direction), contributing to a better hydrophobicity of sized paper and a significant reduction in WATER ABSORPTION of the paper; with the highest reduction in the Cobb test up to the solution concentration of 5%. Also, the results revealed that strength properties of bending stiffness, burst and tensile indices increased due to the ANIONIC STARCH treatment, its consequent absorption and penetration into the paper thickness. The improvement rate was more predominant using up to the 5% concentration. Penetration of a part of sizing agent into the porous structure of paper and resulted improvement in fiber bonding are possible and probable. However, higher concentration and viscosity of the starch solution contributed to the lesser penetration and bonding formation with higher retention on the paper surface which resulted in continuous improvement in paper smoothness. With the sizing solution thickening, tear index decreased due to starch film formation on the paper surface with brittle character. In general, increasing of the ANIONIC STARCH solution up to the 5% could be reported as an optimum level.
