wet-end chemistry

Wet-end chemistry involves the chemical processes inside paper manufacturing that create and strengthen the paper as it is being formed. It includes adding specific chemicals to control factors like fiber bonding, brightness, opacity, and surface properties. These chemicals improve the paper’s quality, handleability, and performance, while also reducing defects and ensuring consistent production. Essentially, wet-end chemistry is about carefully managing the chemical environment where pulp fibers are suspended in water, enabling the fibers to bond properly as they form the solid paper sheet.
