摘要： A water disposable nonwoven web having good MD and CD strength is provided. The nonwoven web is obtained by hydroentangling an airlaid web of no less than 50% by weight of natural cellulose fibers having a fiber length of no more than 3.5 mm and no more than 50% by weight staple fibers having a fiber length of no less than 8.0 mm. The nonwoven web contains no adhesive, binder or thermal bonding fibers. Products containing the disposable nonwoven web meet municipal guidelines for flushability.

摘要： A method to prepare nonwoven webs which have good MD and CD strength, and are water disposable is provided. The method includes hydroentangling an airlaid web of no less than 50% by weight of natural cellulose fibers having a fiber length of no more than 3.5 mm and no more than 50% by weight staple fibers having a fiber length of no less than 8.0 mm. The airlaid web is not laid on a precursor web and no adhesive, binder or thermal bonding fibers are utilized. The airlayering and hydroentangling are conducted in a continuous operation. Products may be obtained according to the method of this invention that meet municipal guidelines for flushability.
