Which Paper Towel is Stronger and
Has More Absorbency?
Decorator or Sparkle?
Introduction

Paper towels are made from softwood trees which contain long fibers. The tree goes thru several processes before it is actually turned into a paper towel. The paper towel is made from pulp in which the water is removed and the fibers then bond into sheets. Also, resin is added to the process to give the paper towel strength (Union). Several layers are then put together with adhesive and then formed into a paper towel (Choudhury). Some paper towels are embossed to form air pockets which help to absorb more liquid and help to add more strength (Union).
The purpose of this experiment is to find out which brand of paper towel, Decorator or …show more content…

The process was then repeated for the second brand of paper towel.
The independent variable for the experiment was the paper towels. The dependent variable was the absorbency and strength. The constants for the experiment were the size of the paper towels that were used, the amount of water, the size of the beaker, the size of the cylinder and the amount of the weight.
Results

The results of the experiment for the test of strength were that the Sparkle brand proved to be the strongest. The average amount that the paper towel would hold before ripping was 583.6 g, which was 159.2 g more than the Decorator brand held. The Decorator brand only held 424.4 g before it ripped.
The results of the experiment for the test of absorbency were that the Sparkle brand proved to be the most absorbent. The average amount of liquid that the Sparkle brand paper towel held was 17.4 mL, which was 4.6 mL more than the Decorator brand held. The Decorator brand only held 12.8 of liquid.
