Durable knitted net
View Patent ↗The present invention is directed to a net, and more specifically to a knitted net comprising a plurality of chain and fill yarns comprising mono-filaments that decreases the overall mass of the net, yet increases the durability of the net. In accordance with the present invention, the netting is used as bale wrap.
1. A method of making a durable knitted net comprising the steps of:
a. providing chain yarns orientated in a first longitudinal direction, wherein said chain yarns comprise one or more mono-filaments;
b. providing fill yarns orientated in a second direction generally transverse to said first direction;
c. interconnecting said chain yarns and said fill yarns on a Raschel machine forming a durable netting, wherein lateral-most ones of said chain yarns generally define opposite outer edges of said net, and wherein at least some of said chain yarns distal said outer edges include a greater number of said mono-filaments than those ones of said chain yarns proximal said outer edges.
2. A method of making a durable knitted net as in claim 1 , wherein said fill yarns comprise mono-filaments.
3. A method of making a durable knitted net comprising the steps of:
a. providing chain yarns orientated in a first longitudinal direction
b. providing fill yarns orientated in a second direction generally transverse to said first direction;
c. arranging said chain yarns into a first longitudinally extending zone;
d. arranging said chain yarns comprising said one or more mono-filaments into a second longitudinally extending zone spaced laterally of said first zone; and
e. interconnecting said chain yarns and said fill yarns on a Raschel machine forming a durable netting,
f. wherein the chain yarns of said first zone exhibit properties which differ from the chain yarns of said second zone.
4. A method of making a durable knitted net as in claim 1 , wherein said yarns are selected from the group consisting of polyamides, polyesters, polyolefins, polyvinyls, polyacrylics, and the combinations thereof.
5. A method of making a durable knitted net as in claim 4 , wherein said yarns are polymeric tapes, filaments, or a combination thereof.
6. A method of making a durable knitted net as in claim 3 , wherein said net is comprised of at least three longitudinally extending zones.
7. A method of making a durable knitted net as in claim 1 , wherein said net comprises a post-treatment.
8. A method of making a durable knitted net as in claim 1 , wherein said fill yarns are elastomeric.
9. A durable knitted net comprising chain yarns of one or more mono-filaments orientated in a first longitudinal direction and fill yarns orientated in a second direction generally transverse to said first direction, wherein said chain yarns and fill yarns are interconnected on a Raschel machine forming a durable netting, wherein lateral-most ones of said chain yarns generally define opposite outer edges of said net, and wherein at least some of said chain yarns distal said outer edges include a greater number of said mono-filaments than those ones of said chain yarns proximal said outer edges.
10. A durable knitted net comprising first, second, and third longitudinally extending zones, said first zone and said third zone are respectively located proximal to opposite outer edges of said net; said second zone is located intermediate said first and third zones; said first and third zones comprise less mono-filaments than said second zone.
