Question

How does fabric softener affect the flammability of different fabrics?

Answer 1

Fabric softeners can make clothes more flammable due to their fat-based nature. They coat fabric surfaces with chemical compounds that neutralize the charge on fibers and impart a softer texture.

Step-by-step explanation:

Fabric softeners contain chemical compounds that coat the surface of fabrics, making them softer and fluffier. This is achieved through electrostatic attraction between the softener molecules and the negatively charged groups on the surface of the fibers. While fabric softeners can improve the texture of fabrics, overusing them can make clothes more flammable, especially those made of natural fibers like cotton and wool. This is because fabric softeners are typically fat-based, which can increase the flammability of fabrics.

Answer 2

Research shows that fabric softeners decrease flame resistance. The flame resistance of a fabric can be increased in a variety of ways. Most often, the fabric is treated with special flame resistant chemicals. Synthetic fabrics, such as polyester, are naturally flame resistant. These fabrics have a property called thermoplasticity, where the fabric naturally melts and shrinks when exposed to flame. This prevents these fabrics from igniting and burning as easily as other fabrics. Basic properties of a fabric, such as porosity, can also influence flame resistance. Larger pores allow for oxygen to be more present in the fabric, making it more flammable.
