Re: What is the difference between 1 ply and 2 ply paper towels??

Hi Vianca, thanks for your question.

Paper towels are made in much the same way that any other paper is made. I wrote an overview of the papermaking process for another question. You can find the answer here: How is paper made?

Paper towels are typically made from chemically pulped softwood fibers or recycled fibers. Mixtures including hardwood fibers are used depending on the type of paper and the desired properties, for example, smoothness. Usually, when a smoother sheet is required, more hardwood fibers are used.

Each ply of the 2-ply paper towel is made separately, then combined using a procedure called embossing. This is responsible for the larger indentions that are found on the surface of paper towels. The main difference between 1-ply and 2-ply paper towels is obvious. The 2-ply sheet is heavier, which enables it to pick up more water since wood fibers are relatively hydrophilic by nature. Also, the structure that is formed when the two layers are put together is better able to wick water between the layers, increasing the speed of pick-up.

Of course, the process is much more complicated. Please submit another question if you need more detail but I hope this has helped.
