Abstract
A nonwoven fabric includes a plurality of discontinuous fibers, a plurality of natural keratin fibers, and a plurality of meltblown fibers. The discontinuous fibers, the natural keratin fibers, and the meltblown fibers form a continuous bonding web structure.
Claims11
A method for manufacturing a nonwoven fabric, the method comprising:
- processing a plurality of discontinuous fibers by a carding machine;
- directing airflow to blow a plurality of natural keratin fibers into spaces between the discontinuous fibers;
- and
- directing the airflow with the discontinuous fibers and the natural keratin fibers to a curtain of semi-molten meltblown fibers, such that the semi-molten meltblown fibers bond the discontinuous fibers and the natural keratin fibers to form a continuous bonding web structure.

An apparatus for manufacturing a nonwoven fabric, the apparatus comprising:
- a carding machine for processing a plurality of discontinuous fibers;
- an air source for providing airflow;
- a feeding channel for directing the airflow to the carding machine to card the discontinuous fibers and to blow a plurality of natural keratin fibers into spaces between the discontinuous fibers;
- a meltblowing machine for providing a curtain of semi-molten meltblown fibers;
- and
- an import channel for directing the airflow with the discontinuous fibers and the natural keratin fibers to the curtain of semi-molten meltblown fibers, such that the semi-molten meltblown fibers bond the discontinuous fibers and the natural keratin fibers to form a continuous bonding web structure.
