ABSTRACT:
A method of laundering textiles is disclosed wherein aminofunctional silicone is dispersed in the rinse water to improve the flow of water out of the textiles during the subsequent spin-separation of water. The resulting textiles contain less residual water and can be dried more rapidly and energy efficiently. The useful aminofunctional silicones are characterized as having either an average of 25 to 125 siloxane units per molecule with 4 to 15 percent of the siloxane units being aminoalkyl substituted or an average of 400 to 600 siloxane units per molecule with 1 to 15 percent of the siloxane units being aminoalkyl substituted.
