Purpose: To find which fabric is most flammable. (Which fabric will catch fire fastest)
Materials:
Lighter
safety goggles
Stop Watch
5cm x 5cm piece of Denim
5cm x 5cm piece of Nylon
5cm x 5cm piece of Polyester
5cm x 5cm piece of Cotton
5cm x 5cm piece of Rayon
5cm x 5cm piece of Acrylic
Procedure:
1) Place a piece fabric under flame. Make sure that each time you do this, the flame is placed at an equal distance from the fabric.
2) As soon as fabric is exposed to flame, begin timing with the stop watch
3) Stop timing when fabric ignites.
4) Put out the fire. Try not to destroy the fabric, it can be used for presentation.
5) Record the time it took for the fabric to ignite
6) Repeat steps 1 to 5 three times for each piece of fabric.
Hypothesis: We think that the Polyester will ignite the fastest, because it is very light, and delicate.
We think that the Nylon will ignite in the longest time because it is much like a plastic.
Results: In order to control all of the variables, we burned and timed each type fabric three times. Below is a table showing our results in seconds.

Fabric 1st Time 2nd Time 3rd Time Average
Denim 5.3 sec 4.8 sec 5 sec 5.03 sec
Nylon 4 sec 3.3 sec 4.1 sec 3.8 sec
Polyester 0.5 sec 0.7 sec 0.7 sec 0.63 sec
Cotton 4.6 sec 4.2 sec 5 sec 4.6 sec
Rayon 3.5 sec 3 sec 2.4 sec 2.97 sec
Acrylic 4.7 sec 5 sec 4.1 sec 4.6 sec
Conclusion:
The Polyester ignited the fastest, which is what we hypothesized. The flame was nearly an inch away from the fabric, when it ignited. It burned up in a...
