Abstract
Stabilizing a textile sheet structure was achieved by forming a plurality of discrete fiber tufts extending from a first face of a fibrous layer of the textile sheet structure, through the fibrous layer and beyond a second face opposite the first face. Each discrete fiber tuft included a plurality discrete fibers. Each discrete fiber tuft was anchored to the first face and the second face of the fibrous layer by joining together the plurality of each discrete fiber tuft at the first face and the second face and bonding the joined plurality of discrete fiber tuft to the first face and the second face.
Claims20
A method for stabilizing a textile sheet structure, the method comprising:
- forming a plurality of discrete fiber tufts extending along a first face of a fibrous layer of the textile sheet structure, through the fibrous layer and beyond a second face opposite the first face, each discrete fiber tuft comprising a plurality of discrete fibers;
- and
- anchoring each discrete fiber tuft to the first face and the second face of the fibrous layer by:
- joining together the plurality of discrete fiber tufts at the first face and the second face;
- and
- bonding the joined plurality of discrete fiber tufts to the first face and the second face.
A stabilized textile sheet structure comprising:
- a plurality of discrete fiber tufts extending along a first face of a fibrous layer of the textile sheet structure, through the fibrous layer and beyond a second face opposite the first face, each discrete fiber tuft comprising a plurality of discrete fibers;
- wherein individual fibers in the plurality of discrete fiber tufts are joined together at both the first face and the second face and the joined plurality of discrete fiber tufts are bonded to the first face or second face to anchor each discrete fiber tuft to the first face and the second face of the fibrous layer.
