METHODS AND SYSTEMS FOR RECYCLING FIBROUS SUBSTRATES
Embodiments of the present disclosure include methods of removing face fibers from a fibrous substrate, systems of removing face fibers from a fibrous substrate, and the like.
1 . A method of removing face fibers from a fibrous substrate, comprising:
cutting a fibrous substrate into cut-portions of the fibrous substrate, wherein the fibrous substrate includes face fibers and a backing structure;
cleaning the cut-portions of the fibrous substrate to remove debris;
detecting for the presence of one or more of the metal objects in the cut portions of the fibrous substrate, and if a metal object is present, removing the metal object;
flattening the cut-portions of the fibrous substrate;
removing the face fibers from the fibrous substrate so that the face fibers and the backing structure are separated;
collecting the face fibers;
cleaning the face fibers; and
collecting the cleaned face fibers.
2 . The method of claim 1 , wherein cleaning the face fibers includes:
carding the face fibers.
3 . The method of claim 1 , wherein cleaning the face fibers includes:
opening the face fibers.
4 . The method of claim 1 or 3 , wherein cleaning the face fibers includes:
washing the face fibers.
5 . The method of any one of claims 1 to 4 , further comprising:
baling the face fibers.
6 . The method of any one of claims 1 to 5 , further comprising:
baling the backing structure.
7 . The method of any one of claims 1 to 6 , wherein removing the face fibers includes:
removing the face fibers from the fibrous substrate using a system selected from: a band blade system, a splitting machine system, a hook knife, and combinations thereof.
8 . The method of any one of claims 1 to 7 , wherein cutting a fibrous substrate into cut-portions of the fibrous substrate includes:
cutting the fibrous substrate using a rip saw.
9 . The method of any one of claims 1 to 8 , further comprising:
segregating the face fiber from the backing structure.
10 . A method of removing face fibers from a fibrous substrate, comprising:
providing a fibrous substrate, wherein the fibrous substrate includes face fibers and a backing structure;
removing the face fibers from the fibrous substrate so that the face fibers and the backing structure are separated;
collecting the face fibers;
cleaning the face fibers; and
collecting the cleaned face fibers.
11 . The method of claim 10 , wherein removing the face fibers includes:
removing the face fibers from the fibrous substrate using a system selected from: a band blade system, a splitting machine system, a hook knife, and combinations thereof.
12 . The method of claim 10 or 11 , wherein cleaning the face fibers includes:
opening or carding the face fibers.
13 . The method of claim 10 or 11 , wherein cleaning the face fibers includes:
opening the face fibers.
14 . The method of any one of claims 10 to 13 , wherein cleaning the face fibers includes:
washing the face fibers.
15 . The method of any one of claims 10 to 14 , further comprising:
baling the face fibers.
16 . The method any one of claims 10 to 15 , further comprising:
baling the backing structure.
