I have learned that some people put fabric softeners in their washer machine so that their clothes aren't stuck together. Fabric softeners have water-soluble polymer that reduces the static electricity on your clothes. I also learned that fabric softeners make the clothes pleasant to touch. This is process is called lubricating. They also were invented in the mid-20 century but the water-soluble polymer wasn't in it. “ There is some evidence to suggest that the overuse of fabric softeners can lead to cancer and environmental damage ” (Brain, Dan). There are many fabric softeners from a variety of brands. Most of them have the same chemical components and function the same way. Fabric softeners come in a liquid or in sheets. Fabric softeners are added to your laundry in order to reduce the negative charge so you don’t get shocked when you touch someone. When the clothes tumble in the dryer, they are coated with this chemical which softens them. “ When the sheets were put in the dryer with laundry, the heat and moisture warmed up the softener and spread it across the clothing” (Brain, Marshall). Although washing machine manufacturers later added an automatic fabric softener dispenser, dryer sheets remain popular, and they're used not only for laundry, but for many off-label purposes such as cleaning and keeping insects and rodents away. The 3 fabrics I am going to use to test my hypothesis is polyester, cotton and silk. Polyester is quick drying and resistant to mold and mildew, easy to wash and able to hold forms well.

Polyester is highly flammable because it is made from polymers. Polyester is made from the same materials that plastic bottles are made from. “Many drink bottles are recycled by being reheated and turned into polyester fibers, which, in addition to being an efficient use, also helps keep polymers out of landfills” (Denis). Cotton is a fiber that is harvested. “It is one of the oldest fibers under human cultivation, with traces over 7,000 years old recovered from archaeological sites” (Denis). Cotton is the most used natural fiber used today. “Silk is a filament fiber formed from proteins secreted by Bombyx mori, or silkworms” (Denis). Silkworms are not really worms, they are caterpillars. “The caterpillars from 30,000 eggs can end up eating 1 ton (about 907 kg) of mulberry leaves and producing 12 pounds (5.5 kilograms) of thread” (Denis).
