Described is a method of making a densified fiber batt that includes the steps of: a) providing a fiber batt with a first plurality of fibers having a first melting point and a second plurality of fibers having a second melting point different from the first melting point; and b) subjecting the fiber batt to heat and pressure in a static press, thereby forming a densified fiber batt having a first surface and an opposed second surface.
1. A method of making a densified fiber batt comprising:
a) providing a fiber batt comprising a first plurality of fibers having a first melting point and a second plurality of fibers having a second melting point different from the first melting point; and
b) subjecting the fiber batt to heat and pressure in a static press, thereby forming a densified fiber batt having a first surface and an opposed second surface,
wherein the densified fiber batt comprises at least 30% by weight of the first plurality of fibers being a plurality of multi-component fibers.
2. The method of claim 1 , wherein the step of providing the fiber batt comprises the steps of:
a′) overlaying the first plurality of oriented fibers and the second plurality of oriented fibers to form a fibrous matrix; and
a″) needle punching the fibrous matrix to form the fiber batt.
3. The method of claim 1 , wherein the method further comprises the step of affixing a decorative portion to the first surface of the densified fiber batt.
4. The method of claim 1 , wherein the static press is a multiple opening static press.
5. The method of claim 1 , wherein subjecting the fiber batt to heat and pressure in the static press comprises subjecting the fiber batt to a temperature from about 180° F. to about 450° F. in the static press.
6. The method of claim 1 , wherein subjecting the fiber batt to heat and pressure in the static press comprises subjecting the fiber batt to a temperature from about 200° F. to about 300° F. in the static press.
7. The method of claim 1 , wherein subjecting the fiber batt to heat and pressure in the static press comprises subjecting the fiber batt to a pressure from about 10 psi to about 100 psi in the static press.
8. The method of claim 1 , wherein subjecting the fiber batt to heat and pressure in the static press comprises subjecting the fiber batt to a pressure from about 50 psi to about 100 psi in the static press.
9. The method of claim 1 , wherein subjecting the fiber batt to heat and pressure in the static press comprises subjecting the fiber batt to a temperature from about 200° F. to about 300° F. and to a pressure from about 50 psi to about 100 psi in the static press.
