A method of forming durable nonwoven fabrics by hydroentanglement includes providing a precursor web comprising a fibrous matrix of staple length fibers and/or substantially continuous filaments. The precursor web is subjected to hydroentanglement on a three-dimensional image transfer device to create a patterned and imaged fabric. Enhanced imaging is achieved by advancing the precursor web onto the movable imaging surface of the image transfer device at a rate substantially equal to the rate at which the image surface moves relative to one or more associated hydroentangling manifolds. Treatment with a polymeric binder composition enhances the integrity of the fabric, permitting it to exhibit desired physical characteristics, including strength, durability, softness, and drapeability. Mechanical compaction of the imaged and patterned fabric, such as by sanforizing, enhances the desired physical properties. |
