Abstract
A method of laundering fabrics includes treating the fabrics with a fabric softening agent, which may be a cationic or nonionic material, and a drape imparting agent, such as a vinyl acetate/vinyl chloride copolymer, in the form of positively charged water-insoluble thermoplastic particles having a softening point of 25.degree.-200.degree. C., especially above 50.degree. C. When selected fabrics are ironed above this softening temperature, the particles coalesce to form a drape imparting film on the fabric while the remaining non-ironed fabrics exhibit a softening benefit.
