Abstract
Abstract The method and product disclosed herein result in a needle-bonded fabric having a tufted fabric visual. This is accomplished by needling an unconsolidated web consisting of layers of two or more different colored fibers with a needle board having a reduced needle density and wherein the needles are arranged in the needle board in a predetermined pattern. The multi-layer web is processed through a fiber locker containing this reduced needle density board at a higher advance rate per stroke than normal production methods so that the space between the needle punches is greatly increased. The web is transported through the fiber locker in a continuous manner and produces the claimed product. One of the layers of the web is a blend of fibers of widely different fiber deniers and color.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
171 words
A needle pattern bonded fiber carpet comprising: (a) a multi-layer web having at least three layers, (b) the first layer being a layer of layered fibers of a certain color and denier, (c) the second layer being at least a single layer of blended fibers of different color and denier from each other in the second layer, (d) the last layer being a carpet scrim layer, (e) said three layers being positioned with said second layer being positioned over said scrim layer, and then said first layer being positioned over said second layer, with said outer surface of said first layer forming the carpet face surface, and (f) said layers being needle-bonded to lock together the three layers, said first and second layers being needled with needles arranged in a pattern to needle the fibers of the second layer, which is a blend of different fibers, into the outer surface of the first layer to provide a pattern of first and second layer fibers on the face surface of the carpet.
Claim 2
Dependent Claim
171 words
A needle pattern bonded fiber carpet comprising: (a) a multi-layer web having at least three layers, (b) the first layer being a layer of layered fibers of a certain color and denier, (c) the second layer being at least a single layer of blended fibers of different color and denier from each other in the second layer, (d) the last layer being a carpet scrim layer, (e) said three layers being positioned with said second layer being positioned over said scrim layer, and then said first layer being positioned over said second layer, with said outer surface of said first layer forming the carpet face surface, and (f) said layers being needle-bonded to lock together the three layers, said first and second layers being needled with needles arranged in a pattern to needle the fibers of the second layer, which is a blend of different fibers, into the outer surface of the first layer to provide a pattern of first and second layer fibers on the face surface of the carpet.
Claim 3
Dependent Claim
38 words
The needle pattern bonded fiber carpet of claim 1 wherein the second layer is a blend of fibers of two different colors and two different deniers, and said colors are different from the colors of the first layer.
Claim 4
Dependent Claim
75 words
A needle pattern bonded fiber carpet as set forth in claim 1 wherein the second layer is composed of two separate layers, each layer being a blend of fibers of different denier and color from each other and from the fibers of the other layer, which forms the first layer, whereby the second layer is actually formed as two separate layers with fibers of four separate colors and at least two different deniers per layer.
Claim 5
Independent Claim
142 words
A method of forming a needle pattern bonded fiber carpet comprising the steps of: (a) positioning a first layer of a layered fiber of a certain color and denier, (b) then positioning over said first layer at least a second layer of layered fibers of different color and denier from that of the first layer, and said second layer being a blend of fibers of two colors and two deniers, (c) needling said layers of fibers to each other while the fiber layers are moving, said needling being carried out partly by needles arranged in a pattern, and (d) the fibers of the second layer being needled into the adjacent surface of and through the first layer to the outer surface of the first layer to provide a pattern of first and second fibers on the outer surface of the first layer.
Claim 6
Independent Claim
142 words
A method of forming a needle pattern bonded fiber carpet comprising the steps of: (a) positioning a first layer of a layered fiber of a certain color and denier, (b) then positioning over said first layer at least a second layer of layered fibers of different color and denier from that of the first layer, and said second layer being a blend of fibers of two colors and two deniers, (c) needling said layers of fibers to each other while the fiber layers are moving, said needling being carried out partly by needles arranged in a pattern, and (d) the fibers of the second layer being needled into the adjacent surface of and through the first layer to the outer surface of the first layer to provide a pattern of first and second fibers on the outer surface of the first layer.
Claim 7
Dependent Claim
58 words
The method of forming a needle pattern bonded fiber carpet as set forth in claim 4 wherein a scrim is added to the outer surface of the second layer, and the tufts of the first and second fiber layers on the outer surface of the first layer are consolidated back into the face surface of the first layer.
