Effects of Different Solutions on Elasticity Percentage of Various Fabrics

Overview

Objectives/Goals What type of fabrics will retract back with which solution, with the amount of 10 trials for each fabric. Methods/Materials fabrics cotton, lycra, nylon, and polyester. Solutions bleach, ammonia, baking saod, salt, and control. Two 25 pounds weight, and 11 long poles,room temp water. Results Bleach caused the fabric to streatch, but the elasticity was so trong that the fabric retracted back further than it's normal size. Conclusions/Discussion After completing my project I found that my hypothesis was incorrect and correct. I stated that the solution baking soda would cause less effect on the elasticity of the four fabrics: cotton, lycra, nylon and polyester. In the correct part of my hypothesis I stated that the bleach solution would have an effect on the elasticity of the fabrics and the solution will make the fabrics stretch more. From my results I discovered that bleach stretched the fabrics the most. I also discovered that all the solutions had more effect on the cotton fabric.
