Burning Fabrics Question Problem: Does material or fabric type of clothing affect the rate of burning the material? Problem Statement This experiment was made to help people all around the world. It tested fabrics that were flammable and inflammable. This could reduced the amount of deaths caused by fires because poeples clothes would not catch on fire as easily. Background Information We are testing the flammibility of different fabrics. Fire is combustion or burning, in which substances combine chemically with oxygen from the air and typically give out bright light, heat, and smoke. Fire can be caused by a lit match, focused light, friction, lightning, or something else burning nearby. Flame is the visible part of fire. When the flame ignites the gases, the fire spreads. The glow of a flame is complex. The dominant color in a flame changes with temperature. Near the ground, where most burning is occurring, the fire is white, the hottest color possible for organic material in general, or yellow. Above the yellow region, the color changes to orange, which is less hot. Then red, which is cooler still. Above the red region carbon particles are visible as black smoke (Wikipedia.com, 10-18-2012). Fires could also burn humans. To tell the difference between minor and serious burns the first step is to see the extent of damage caused by the burn. There are different kinds of serious burns: first degree burns, second degree burns, and third degree burns. First degree burns are the least serious of burns. The skin will usually be red, most likely there will be swelling, and pain is sometimes present. Second-degree burns are when the first layer and the second layer of skin are burned. Blisters develop, skin is intensely reddened and has a blotchy appearance, severe pain and swelling are present. Minor burns are cooled, covered with a sterile gauze bandage, and the pain is relieved by pain relievers, this is the treatment for first degree burns and some second degree burns. Minor burns usually heal without further treatment. Third degree burns are the most serious burns and involve all layers of the skin burned and cause permanent damage to tissues. Areas may be charred black or appear dry and white. These burns are in need of emergency medical help. How fast an object or organism can be burned depends on its flammability. Flammability is how easily something will burn or ignite, causing fire. The flammability of an object is on a rating from 1 to 4. The ratings are: 0-Materials that will not burn; 1-Materials that must be preheated before they will ignite; 2-Materials that must be moderately heated or exposed to relatively high ambient temperatures before they will ignite.3-Liquids and solids that can ignite under almost all temperature conditions; 4-Materials which will rapidly vaporize at normal temperatures, or are readily dispersed in air and which burn readily. Clothing flammability is the speed at which fabrics we use in clothing ignite and the rate they burn once ignited. Materials such as cotton, rayon and acrylic are generally more combustible than 100 percent polyester, nylon, wool and silk. Fine threads with open weaves are more combustible than heavy, closed weaves of the same material.

~Cut all the pieces of fabric the same size to the measurement of 20cm by 20cm
~Set up work area in a location that will start a fire
~Light each piece of fabric on fire in turn with a lighter
~Immediately start the timer
time taken to burn
height of flame
color of flame
condition of the fabric once the fabric has extinguished
~Record all data
~Clean up work area Variables Independent variable: fabric Dependent variable: amount of time it take for fabric to burn Control Variable: way of lighting the fabric, place, size, and temperature Materials Safe area to set fire to fabric
Steno pad
Cotton fabric (20cm by 20cm)
Tulle fabric (20cm by 20cm)
Silk fabric (20cm by 20cm)
Felt fabric (20cm by 20cm)
Nylon fabric (20cm by 20cm) Our results
Type of Fabric Time Taken to Burn
Cotton: #1: 5:12 #2: 9:35
Tulle: #1: 4:00 #2: 3:49
Silk: #1: 6:30 #2: 5:15
Felt: #1: 3:00 #2: 2:50 Data fabrics were lighted by a lighter. The lighter then could not function because it didn't have gas so the scientist switched to matches. This could have greatly affected the data because one method of lighting the fabric could have been more effective than the other. Therefore when doing the experiment either use a lighter with full gas or a select number of matches that stays the same for every piece of fabric. Analysis Conclusion The data did not support the hypothesis. the hypothesis stated that if the cotton has a high flammability is true about research then it will take a shortest time for cotton to disintegrate. the events did not occur this way though and the cotton took the most time to burn. THE END The results of this experiment will be helpful because items of clothing could be produced that are less flammable if manufacturers used less flammable fabrics to make their clothing. This will help people all around, especially firefighters and other professions that deal a lot with heat and fire. For example, firefighters will be less endangered of burns to their body if their clothes are less flammable.
