Rafiq Karimi Jr. Not consumers wearing lower-maintenance casual clothes to work. Not retailers selling inexpensive «disposable» fashions. Not telecommuters staying in their jammies. Not smoking bans lessening the need for trips to the cleaners. Certainly not garment-makers replacing silk, wool and other cleeaning with cotton and polyester blends that hold up to laundering in standard washing machines. Hundreds of dry cleaners in Illinois have closed in the past two decades, but Karimi’s Westchester-based CD One Price Cleaners is among those trying to do dry cleaning business make money in an industry that, despite a rebounding economy, is shrinking like wool in hot water.
