There are several kinds of odor preventing and odor destroying treatments for textiles. For the most part, they work by killing 1 or inhibiting 2 the bacteria and fungi 3 that cause odors. For example, these socks contain Quaternary Ammonium Compounds, or QACs. QACs are complex molecules 5 with one end that binds 6 tightly to the surface of the treated fibers 7. The rest of the molecule 4 is made up of a positively 8 charged nitrogen atom and a long chain of carbons. You can think of the QAC molecule as an electrically charged sword. The long chain of carbons punctures 9 the cell membrane 10 of a microbe, allowing the charged nitrogen to electrically disrupt the cell’s contents. Since nothing is bound permanently 11 to the now dead cell, the QAC doesn’t lose strength and is ready to destroy the next offending microbe that crosses its path.
