Abstract
A nonwoven web including a first layer that includes continuous fibers having a first polymer component and a second layer that includes continuous fibers having a second polymer component. The melting point of the second polymer component is less than the melting point of the first polymer component, and the first layer is hydroentangled with the second layer.
Claims22
A nonwoven web comprising:
- a first layer comprising continuous fibers including a first polymer component;
- and
- a second layer comprising continuous fibers including a second polymer component, the melting point of the second polymer component being less than the melting point of the first polymer component, the first layer being hydroentangled with the second layer.
A method of making a patterned nonwoven web, comprising:
- forming a nonwoven web comprising:
- a first layer comprising continuous fibers;
- and
- a second layer comprising continuous fibers, the melting point of the continuous fibers of the second layer being less than the melting point of the continuous fibers of the first layer;
- thermal bonding the first layer to the second layer;
- subjecting the thermally bonded first and second layers to a hydroentanglement process so as to form a pattern in the first layer;
- and
- through air drying the hydroentangled first and second layers so that the continuous fibers of the second layer melt.
