Abstract
A method of forming durable nonwoven fabrics by hydroentanglement includes providing a precursor web comprising a blend of matrix fibers, lyocell fibers, and fusible binder fibers. The precursor web is subjected to hydroentanglement on a three-dimensional image transfer device to create a patterned and imaged fabric. Fabrics formed in accordance with the present invention exhibit significant improvements in strength while remaining drapeable and are capable of withstanding multiple laundry washing with nominal shrinkage.
