How Do Paper Towels Absorb Water? Capillary Action
Paper towels absorb water through a process called capillary action, which involves the combination of adhesion, cohesion, and surface tension of the water molecules and the cellulose fibers present in the paper towel.
Capillary action is the ability of a liquid to flow through narrow spaces without the assistance of external forces like gravity.
In the case of paper towels, the cellulose fibers that make up the towel have small gaps and spaces in between them.
When these fibers come into contact with water, the adhesion between the water molecules and the cellulose fibers causes the water to spread out and be absorbed into the towel.
Additionally, the cohesion between the water molecules themselves and the surface tension of the liquid also aids in the absorption process.
Paper towels are designed with cellulose fibers that contain small gaps and spaces which facilitate the absorption of water through capillary action.
This involves the interaction of adhesion, cohesion, and surface tension between the water molecules and the cellulose fibers, allowing the water to spread out and be absorbed effectively.

The composition of paper towels plays a significant role in their absorbency capacity. Let’s take a closer look at how paper towels are made and what makes them so absorbent.
Discuss The Composition Of Paper Towels
Paper towels are made of cellulose fibers derived from wood pulp. These fibers are processed and pressed into thin sheets that are then dried, cut, and packaged.
Paper towels are a combination of both natural and synthetic fibers, including:
- Cellulose fibers
- Rayon
- Polypropylene
The exact composition of paper towels may vary between brands, but cellulose fibers are the primary component responsible for their absorbency.
Highlight How Cellulose Fibers Help In Absorbing Water
Cellulose fibers are hydrophilic, meaning they attract and hold onto water molecules. The porous nature of cellulose fibers allows water to penetrate the sheets of paper towel.
As the water is absorbed by the cellulose fibers, capillary action pulls the water through the tiny spaces and pores between the fibers.
This process is aided by the creping of the paper towel sheets, which creates a more porous structure that allows for greater water absorption.
In addition to their absorbency, cellulose fibers are also biodegradable, making paper towels an eco-friendly option for cleaning up spills and messes.
The composition of paper towels is primarily made up of cellulose fibers, which are responsible for their absorbency.
These hydrophilic fibers have a porous structure that allows for the absorption of water molecules, aided by the creping of the paper towel sheets.
So next time you reach for a paper towel to clean up a spill, you’ll know exactly how it works to absorb the water.
