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.
Claims10
A method of making a nonwoven fabric, comprising the steps of:
- providing a precursor web comprising a blend of matrix fibers, lyocell fibers and binder fibers;
- providing a three-dimensional image transfer device;
- hydroentangling said precursor web on said image transfer device to form a patterned and imaged nonwoven fabric;
- and
- drying the imaged nonwoven fabric to at least partially heat-bond the fabric.
A nonwoven fabric, comprising:
- a blend of matrix fibers, lyocell fibers and binder fibers, said fabric being imaged and patterned by hydroentanglement on a three-dimensional image transfer device.
A nonwoven fabric, comprising:
- a blend of matrix fibers, lyocell fibers and binder fibers, said fabric being imaged and patterned by hydroentanglement on a three-dimensional image transfer device;
- said fabric comprising matrix fiber in the range of about 50% to about 75% by weight, lyocell fiber in the range of about 20% to about 45% by weight, and binder fiber in the range of about 3% to about 20% by weight.
A nonwoven fabric, comprising:
- a blend of matrix fibers, lyocell fibers and binder fibers, said fabric being imaged and patterned by hydroentanglement on a three-dimensional image transfer device;
- said fabric comprising matrix fiber in the range of about 50% to about 75% by weight, lyocell fiber in the range of about 20% to about 45% by weight, and binder fiber in the range of about 3% to about 20% by weight, said nonwoven fabric capable of withstanding at least 5 laundry machine washings.
