Abstract
A material having a multi-denier base material layer including a plurality of fine denier fibers, the fine denier fibers of less than about 10 dpf, and a plurality of large denier filaments intermixed with the fine denier fibers which form channels in a longitudinal direction of the material, the large denier filaments of greater than about 10 dpf. A method of producing a multi-denier cover material is also disclosed.
Claims53
A cover material comprising:
- a base material layer including a plurality of fine denier fibers, having a fiber denier of less than about 10 dpf;
- and
- a plurality of large denier filaments bonded to the base material layer, having a filament denier greater than about 10 dpf and forming a plurality of channels in the cover material.
A cover material comprising:
- a first nonwoven layer comprising a plurality of fine denier fibers, the fine denier fibers having a denier less than about 10 dpf;
- and
- a plurality of large denier filaments forming a plurality of channels, the large denier filaments having a denier greater than about 10 dpf.
A method for producing a multi-denier nonwoven material comprising the steps of:
- producing a base material layer comprising a plurality of fine denier fibers of less than about 10 dpf;
- combining a plurality of large denier filaments with the fine denier fibers to form a plurality of channels, the large denier filaments of at least about 10 dpf;
- and
- bonding the large denier filaments to the fine denier fibers.
