(44,397 posts)Fabric softeners coat the surface of a fabric with chemical compounds that are electrically charged, causing threads to "stand up" from the surface so the fabric feels softer and makes it fluffier. Cationic softeners bind by electrostatic attraction to the negatively charged groups on the surface of the fibers and neutralize their charge. The long aliphatic chains then line up towards the outside of the fiber, imparting lubricity.
Electrically conductive fabric softener chemicals may also prevent static charge buildup in clothes dryers. Other functions manufacturers claim include less friction during ironing, increased stain resistance, reduced wrinkling and pilling, and lower drying time. Most contain fragrances. Cationic fabric softeners are added during the rinse cycle rather than the wash cycle because they can interfere with detergent cleaning action.[citation needed] In addition to fabric softening chemicals, fabric softeners may include acids or bases to maintain optimal pH for absorption, silicone-based anti-foaming agents, emulsion stabilizers, fragrances, and colors.
