1. A method of treating a fabric, said method comprising:
- A. a washing step, wherein said washing step comprises contacting said fabric with an effective amount of a detergent composition, thereby forming a washed fabric, wherein said detergent composition comprises;
i. a surfactant system comprising an anionic surfactant and nonionic surfactant in a weight ratio of from about 1.1;
1 to about 4;
1;
ii. a silicone; and
iii. a cationic polymer, wherein the cationic polymer is characterized bya. having a weight average molecular weight of from about 5 kDaltons to about 200 kDaltons;
b. comprising a first structural unit derived from acrylamide, and a second structural unit derived from DADMAC; and
c. wherein said first structural unit and said second structural unit are in a structural unit ratio of from about 5;
95 to about 45;
55; and
thenB. a rinsing step, wherein said washed fabric is contacted with an effective amount of a softener composition, thereby forming a treated fabric, wherein said softener composition comprises a fabric softening active (FSA) selected from the group consisting of a quaternary ammonium compound, silicone, fatty acids or esters thereof, sugars, fatty alcohols, alkoxylated fatty alcohols, polyglycerol esters, oily sugar derivatives, wax emulsions, fatty acid glycerides, or mixtures thereof.
