Abstract
Strong, low basis weight, spontaneously dispersible sheets of modified cellulosic fibers. The sheets are prepared from modified cellulosic fibers such as cross-linked carboxymethyl cellulose or essentially acidic sodium carboxymethyl cellulose. Mixtures of modified fibers with unmodified fibers are also disclosed. The process of preparing the sheets comprises the steps of airlaying the fibers to form an airfelt, increasing the moisture content of the airfelt, and compacting the moisturized airfelt.
