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.
Claims16
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.

The method of claim 10, further comprising:
- carding the discontinuous fibers and the natural keratin fibers by an air carding machine before directing the airflow with the discontinuous fibers and the natural keratin fibers to the curtain of semi-molten meltblown fibers;
- and
- wherein directing the airflow with the discontinuous fibers and the natural keratin fibers to the curtain of semi-molten meltblown fibers comprises:
- directing the airflow with the carded discontinuous fibers and the carded natural keratin fibers to the curtain of semi-molten meltblown fibers.
1 more element
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.
