Paper Towel Absorbency Experiment

Tests of absorbency: Absorbency was tested in one of two ways, speed of absorption and volume of absorption. When testing speed, the more rapidly the water moves through the towel, the more absorbent the towel. When testing volume, the more water a towel will hold, the more absorbent the towel. (5) Place a paper towel in the embroidery hoop. Draw a circle 2 inches in diameter in the center of the towel. a) Place drops of water in the center of the towel. Count the number of drops...

Lab Report on Paper Towels

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...

Does Price Indicate How Absorbent Paper Towels Are? Problem statement: The purpose of this experiment is to determine if the price of paper towels reflects the absorbency of the paper towels. Relevance: I became interested in this idea while trying to save money on my grocery bill. If the cheaper paper towels work just as well or better, I can save money by purchasing them. The information gained from this experiment can help consumers get the best absorbency for the lowest price. Literature...

Durability of Paper Towels

Durability of Wet Paper Towels Purpose: Find the strongest paper towel brand when wet. Background: Paper towels are used for a variety of purposes. Some of which include napkins, absorbing liquids, cleaning messes and more. For paper towels to effective,they must be relatively durable while wet. However, paper towel brands make it hard to tell which is the most strong by claiming that they are the most durable. Hypothesis: If we add weight to each piece of wet paper towel, then I think Bounty...

Finding the best quality paper towel Question: Which paper towel has the highest quality overall? Background: Past tests of the highest quality paper towel showed that Bounty was the best choice for a kitchen paper towel. Although it wasn’t the most absorbent, which was Brawny, it was rather strong in both durability and absorbency. (consumerreports.org) Industrial and 7th generation are most commonly used in public places such as; School bathrooms, public restrooms and public sinks...

Science Test- Paper Towels

“Which kitchen paper is the best at absorbing liquid?” Scientific Principles- Since paper towels are used to pick up liquids, the volume of liquid it can hold is important. The amount of liquid a towel can absorb can be measured by the volume of liquid it picks up. Aim- To investigate which kitchen paper is the best at absorbing most liquid. Hypothesis- I think that Viva/Kleenex will be the best at absorbing most of the liquid because I think it’s the thickest paper towel and I think that...

Paper Towel

A paper towel (also called kitchen roll) is an absorbent textile made from paper instead of cloth. Unlike cloth towels, paper towels are disposable and intended to be used only once. Paper towels soak up water because they are loosely woven which enables water to travel between them, even against gravity. Paper towels can be individually packed (as stacks of folded towels or held coiled). Paper towels have almost the same purposes as conventional towels, such as drying hands, wiping windows, dusting...
