Definition: |
|
Addition of sizing agents either to the stock (internal sizing) or to the surface of a paper (surface sizing), in order to increase its surface strength, and its resistance to the penetration and spreading of aqueous liquids. |

Sizing operations are carried out primarily to provide paper with resistance to penetration by aqueous solutions. The treatment also provides better surface characteristics and improves certain physical properties of the paper sheet, such as surface strength and internal bond. Two basic methods of sizing are available to the papermaker: internal sizing and surface sizing. These are used either as sole treatments or in combination. Internal sizing utilizes rosin or other chemicals to reduce the rate of water penetration by affecting the contact angle. Surface sizing typically utilizes starch particles to fill in the surface voids in the sheet, reducing pore radius and therefore the rate of liquid penetration. |
