1. A method for treating fabrics in a washing machine to provide at least one fabric protective property to a fabric, comprising the steps of:

  • (1) depositing a first fabric treatment composition onto the fabric in a first treatment liquor, wherein the first fabric treatment composition comprises;

    a) a first amount of a hydrophobic agent that does not cause any significant color change, nor impart any discoloration to a fabric, characterized as having a melting point or glass transition temperature of less than 100°

    C.;

    b) a first amount of a fluoropolymer; and

    c) a first effective amount of a zeta potential modifier, such that the first treatment liquor has a zeta potential that is positive and greater than zero millivolts; and

    (2) curing the fabric at a drying temperature above ambient temperatures but less than 100°

    C.;

    wherein;

    i) the fabric protective property is selected from the group comprising;

    increased water repellency, increased oil repellency, increased soil and stain release, improved hand-feel, improved softness, improved resistance to damage, and any combination thereof;

    ii) the hydrophobic agent is not a fluoropolymer;

    iii) the zeta potential modifier comprises a cationic or cationically modified material; and

    v) the ratio of hydrophobic agent to zeta potential modifier is at least 1;
