A nonwoven fabric treated to provide pleat retention, static control, stain-resistance, and antimicrobial efficacy for a window shade application. The stain-resistant finish does not significantly interfere with the subsequent printing, as well as the pleating and gluing of the nonwoven fabric into a window shade. A test method to determine the degree of stain resistance to common household products is also described.
