Alternate embodiments include layers comprised of polyethylene terephthalate bottle-fiber matrix and/or jute or coir fibers. A method of manufacturing the floating island module described above.
Claims16
A floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix comprised of post-consumer carpet fibers and further comprising a top covering and a bottom covering around each layer, wherein the top covering and bottom covering are each comprised of materials that are resistant to abrasion and ultraviolet light and permeable to water and gasses, wherein each module has a perimeter, and wherein the top covering and bottom covering are fusion welded together around all or a portion of the perimeter of each layer.
A floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix comprised of post-consumer carpet fibers and further comprising a top covering and a bottom covering around each layer, wherein the top covering and bottom covering are each comprised of materials that are resistant to abrasion and ultraviolet light and permeable to water and gasses, wherein the top covering and the bottom covering each has an outer edge, and wherein one or more end caps are placed over the outer edges of the top covering and bottom covering and fusion welded to the top covering and bottom covering.
A floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix comprised of post-consumer carpet fibers, wherein the layers of post-consumer carpet fiber matrix are vertically stacked and attached to each other with layer attachments loops that are punched through the layers.
A floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix comprised of post-consumer carpet-fiber matrix and one or more layers of polyethylene terephthalate bottle-fiber matrix, wherein the modules are arranged in rows, with one row of modules on top of another, and wherein one of the rows of modules is positively-buoyant and another row of modules is negatively-buoyant.
A method of manufacturing a floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix, comprising the steps of:
- (a) providing an upper scrim roll that supplies top-cover scrim to form a top covering;
- (b) providing a lower scrim roll that supplies bottom-cover scrim to form a bottom covering;
- (c) blowing loose post-consumer carpet fibers between the top-cover scrim and the bottom-cover scrim via a fiber feeder;
- (d) spraying uncured two-part polyurethane foam resin droplets onto the loose post-consumer carpet fibers as they are blown between the top-cover scrim and the bottom-cover scrim;
- (e) compressing the loose post-consumer carpet fibers to a desired packing density as they travel along a compression table to form a post-consumer carpet matrix;
- (f) passing the post-consumer carpet matrix between an upper vacuum draw and a lower vacuum draw, wherein the upper vacuum draws a first portion of the two-part polyurethane foam resin droplets toward and against an inside surface of the top-cover scrim, and the lower vacuum draw pulls a second portion of the two-part polyurethane foam resin droplets toward and against an inside surface of the bottom-cover scrim, thereby bonding the post-consumer carpet matrix to the top and bottom coverings;
- and
- (g) cutting the post-consumer carpet matrix into desired lengths with a mechanical cutter to form a layer of post-consumer carpet matrix.
A method of manufacturing a floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix, comprising the steps of:
- (a) providing an upper scrim roll that supplies top-cover scrim to form a top covering;
- (b) providing a lower scrim roll that supplies bottom-cover scrim to form a bottom covering;
- (c) blowing loose post-consumer carpet fibers between the top-cover scrim and the bottom-cover scrim via a fiber feeder;
- (d) placing an internal rope, webbing or cable between the top-cover scrim and the bottom-cover scrim as the loose post-consumer carpet fibers are blown between the top-cover scrim and the bottom-cover scrim;
- (e) compressing the loose post-consumer carpet fibers to a desired packing density as they travel along a compression table to form a post-consumer carpet matrix;
- and
- (f) cutting the post-consumer carpet matrix into desired lengths with a mechanical cutter to form a layer of post-consumer carpet matrix.
A method of manufacturing a floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix, comprising the steps of:

- (c) blowing loose post-consumer carpet fibers between the top-cover scrim and the bottom-cover scrim via a fiber feeder;
- (d) compressing the loose post-consumer carpet fibers to a desired packing density as they travel along a compression table to form a post-consumer carpet matrix;
- (e) cutting the post-consumer carpet matrix into desired lengths with a mechanical cutter to form a layer of post-consumer carpet matrix;
- and
- (f) wherein each layer of post-consumer carpet matrix has a perimeter, securing rope, webbing or cable around all or a portion of the perimeter of each layer.
A method of manufacturing a floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix, comprising the steps of:
- (a) providing an upper scrim roll that supplies top-cover scrim to form a top covering;
- (b) providing a lower scrim roll that supplies bottom-cover scrim to form a bottom covering;
- (c) blowing loose jute fibers between the top-cover scrim and the bottom-cover scrim via a fiber feeder;
- (d) spraying uncured two-part polyurethane foam resin droplets onto the loose jute fibers as they are blown between the top-cover scrim and the bottom-cover scrim;
- (e) compressing the loose jute fibers to a desired packing density as they travel along a compression table to form a jute matrix;
- (f) passing the jute matrix between an upper vacuum draw and a lower vacuum draw, wherein the upper vacuum draws a first portion of the two-part polyurethane foam resin droplets toward and against an inside surface of the top-cover scrim, and the lower vacuum draw pulls a second portion of the two-part polyurethane foam resin droplets toward and against an inside surface of the bottom-cover scrim, thereby bonding the jute matrix to the top and bottom coverings;
- and
- (g) cutting the jute matrix into desired lengths with a mechanical cutter to form a layer of post-consumer carpet matrix.
A method of manufacturing a floating island comprising one or more modules each comprised of one or more layers of permeable and porous matrix, comprising the steps of:
- (a) providing an upper scrim roll that supplies top-cover scrim to form a top covering;
