How Are Paper Towels Made?

Paper towel manufacturing is accomplished through two different manufacturing procedures: creping and embossing.

The first step in the process of making soft tissue paper is creating paper pulp, which can be generated from recycled or new materials. The paper pulp is processed with a Yankee dryer, a drying cylinder heated by steam. This dryer puts the pulp through a process called creping. The hood above the roller dries the pulp with a forceful heat as the roller turns and a fine blade scrapes the tissue down to the soft, desired thickness. The tissue does not get completely scraped away, because the roller is first sprayed with adhesives, such as LD Davis protein adhesive.

Creping provides the paper with flexibility and stretch and creates more open areas to absorb water. Throughout the creping process, the mechanical action of the blade disrupts the fiber-to-fiber bonds within the paper and forms a micro-fold structure inside the piece of paper.

Embossing implies that the top of towel is modified from the flat working surface to some shaped surface, to ensure that you will find areas which are raised in the flat background. The embossing process develops an empty space between the papers, allowing the paper wipe to hold more water.

Protein Glue in Creping

Protein glue, also known as hide glue, is composed of technical gelatin, usually extracted from hides and/or bones of pigs and cattle. Our protein glue has been developed to bond together the individual layers of toilet paper and paper towel sheets. The paper used to create paper towels is not pressed as hard as other types of paper products to give it a gentle, softer texture. Two of these soft layers of paper are then carefully bonded with our eco-friendly, non-toxic protein adhesive to form one water-absorbing sheet. Another type of adhesive called PVOH glue (polyvinyl alcohol) can also be used in creping. Like protein adhesive, it is water-soluble and eco-friendly.

At the same time, the layers are embossed so that small pockets of air are trapped within the sheets. These pockets help to absorb water, and the absorption qualities of the paper towel depend on the type of fibers used and how the sheets are embossed.
