Method of manufacturing a compost filter sock that is linearly stable during filling
A compost filter netting comprises plastic netting formed in a tube having a diameter of 6″-36″ wherein the plastic netting includes netting openings of ⅛-⅜″ and configured to be filled with compost to form a compost filter sock, wherein the linear length of the compost filter sock is not less than 93% of the linear length of the originally manufactured empty compost filter netting. A method of forming a compost filter sock using the compost filter netting and the compost filter sock made thereby is disclosed. The compost filter netting substantially eliminates the problem of miscalculation of shrink rate that is problematic for in field applications.
1. A method of manufacturing a compost filter sock that is linearly stable during filling, comprising the steps of:
providing a warp knitted compost filter netting comprising netting formed in a tube having a diameter of 6 inches to 36 inches wherein the netting includes netting openings and of an original manufactured linear length, wherein the compost filter netting includes warp and weft threads, and wherein the warp threads extend longitudinally along the longitudinal axis of the tube and substantially parallel to each other while the weft threads extend perpendicular to the longitudinal axis of the tube;
sealing a first end of the compost filter netting;
filling the compost filter netting with compost to full capacity to form a compost filter sock; and
sealing a second end of the compost filter netting, wherein a linear length of the compost filter sock is not less than 93% of the original manufactured linear length of the compost filter netting.
2. The method of manufacturing a compost filter sock according to claim 1 wherein the circumference of the originally manufactured empty compost filter netting is at least 90% of the circumference of the compost filter sock.
3. The method of manufacturing a compost filter sock according to claim 2 further including the step of providing an integral stake mounting indicia in the sock formed by a distinctly colored thread inlaid between two warp threads at the appropriate intervals to form the indicia in the compost filter netting.
4. The method of manufacturing a compost filter sock according to claim 3 wherein the linear length of the compost filter sock is not less than 95% of the length of the originally manufactured empty compost filter netting.
5. The method of manufacturing a compost filter sock according to claim 4 wherein the circumference of the originally manufactured empty compost filter netting is at least 95% of the circumference of the compost filter sock.
6. The method of manufacturing a compost filter sock according to claim 1 wherein the netting is formed of a polyolefin or a polyamide material.
7. The method of manufacturing a compost filter sock according to claim 6 further including providing at least one expansion pleat within the sock.
8. A method of manufacturing a compost filter sock that is linearly stable during filling, comprising the steps of:
A) providing a warp knitted manmade synthetic netting formed in a tube having a diameter of 6 inches to 36 inches wherein the manmade synthetic netting includes netting openings and of an original manufactured linear length, wherein the manmade synthetic netting includes warp and weft threads, and wherein the warp threads extend longitudinally along the longitudinal axis of the tube and substantially parallel to each other, while the weft threads extend perpendicular to the longitudinal axis of the tube, and providing compost for filling the manmade synthetic netting;
B) placing the manmade synthetic netting on a pneumatic nozzle;
C) sealing one end of the manmade synthetic netting on the pneumatic nozzle while maintaining the opposite end and the remainder of the manmade synthetic netting on the pneumatic nozzle;
D) filling the manmade synthetic netting with compost to full capacity; and
E) sealing the remaining open end of the manmade synthetic netting, wherein the linear length of the compost filter sock from the one sealed end to the opposed sealed end is not less than 93% of the linear length of the originally manufactured linear length of the manmade synthetic netting from the same two points forming the sealed ends.
9. The method of manufacturing a compost filter sock according to claim 8 wherein the circumference of the originally manufactured manmade synthetic netting is at least 90% of the circumference of the compost filter sock.
10. The method of manufacturing a compost filter sock according to claim 9 wherein the manmade synthetic netting is one of polyolefin or polyamide and further including integral stake mounting indicia in the sock formed by a distinctly colored thread inlaid between two warp threads at the appropriate intervals to form the indicia in the manmade synthetic netting.
11. The method of manufacturing a compost filter sock according to claim 10 wherein the linear length of the compost filter sock is not less than 95% of the length of the originally manufactured manmade synthetic netting, and wherein the circumference of the originally manufactured manmade synthetic netting is at least 95% of the circumference of the compost filter sock, and further including at least one expansion pleat within the sock.
