It slightly depends upon the type of softener you use. However, generally, the fabric softeners coat the fabric’s surface with some chemical compounds. They are electrically charged, which causes threads of the fabric to erect, and thus, you will get a softer and fluffier texture in the end. The fabric conditioners also work towards making garments fresh and free of wrinkles so that you can easily iron them. So, you can consider them to give back the softness of clothes.
