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.

Claims (10)

1. A top-of-bed nonwoven fabric, comprising:

a carded blend of matrix fibers, lyocell fibers and staple length binder fibers, said fabric being imaged and patterned by hydroentanglement on a three-dimensional image transfer device prior to thermal bonding, and subsequently thermal bonded by heat-activation of said staple length binder fibers, said nonwoven fabric being free of resin binder, and capable of withstanding at least 5 laundry machine washings.

2. A top-of-bed nonwoven fabric, comprising:

a carded blend of matrix fibers, lyocell fibers and staple length binder fibers, said fabric being imaged and patterned by hydroentanglement on a three-dimensional image transfer device prior to thermal bonding, and subsequently thermal bonded by heat-activation of said staple length binder fibers;

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 staple length binder fiber in the range of about 3% to about 20% by weight, said nonwoven fabric being free of resin binder, and capable of withstanding at least 5 laundry machine washings.

3. A top-of-bed nonwoven fabric, comprising:

a carded blend of matrix fibers, lyocell fibers and staple length binder fibers, said fabric being imaged and patterned by hydroentanglement on a three-dimensional image transfer device prior to thermal bonding, and subsequently thermal bonded by heat-activation of said staple length binder fibers;

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 5% to 10% by weight, said nonwoven fabric being free of resin binder, and capable of withstanding at least 5 laundry machine washings.

4. A method of using the nonwoven fabric of claim 1 , including:

employing said nonwoven fabric for “top-of-bed” applications including comforters, pillows, dust ruffles, and the like.
