The granted patent (Publication Number: US11919278B2) discloses a method for producing a densified fiber batt. The method involves providing a fiber batt containing two different sets of fibers with distinct melting points and subjecting it to heat and pressure in a static press. This process results in the formation of a densified fiber batt with specific characteristics, including a composition of at least 30% by weight of multi-component fibers.

Furthermore, the method includes additional steps such as overlaying oriented fibers to form a fibrous matrix, needle punching the matrix to create the fiber batt, and affixing a decorative portion to the surface of the densified fiber batt. The parameters for the heat and pressure treatment in the static press are defined within a range of temperatures and pressures, ensuring the desired thickness and density of the final product. The patent also specifies variations in the composition of the fiber batt, with different percentages of multi-component fibers and polyester fibers, offering flexibility in the manufacturing process.
