When buying a fishing net making machine, your choice between single and double needle bar designs starts with the net you want to manufacture. Both are available for knotless fishing net production, but the right choice depends on yarn specifications, mesh construction, and production requirements.
Chenye’s fishing net making solutions include SRO single needle bar and DRCP double needle bar machines. For buyers, the key question is which configuration can consistently reproduce the required net at a practical production cost.
A single needle bar Raschel machine uses an oil-immersed linkage mechanism; the advantage of this mechanism lies in its high load-bearing capacity, enabling the production of nets with high density and heavy weight, as well as the ease of adjusting the stroke of the tongue needles. This machine utilizes a single needle bed mechanism with eight feeding bars, enabling single-sided loop formation – making the net surface visually clear and the loop-forming process easy to observe and adjust.
The double needle bar Raschel machine uses an open cam mechanism, which is easier to maintain; however, its loop-forming process is more complex, as it requires the coordination of two sets of spindles. The machine also uses eight feeding bars, allowing for the production of more intricate and diverse types of nets, though this imposes higher demands on setup and operation.
Chenye’s SRO single needle bar Raschel machine and double needle bar machine can produce knotless fishing nets, sports nets, safety purse nets, and deep-sea nets.
CHENYE knotless net making machines can process a wide range of raw materials, including polyester (PET), polypropylene (PP), nylon (PA), ultra-high-molecular-weight polyethylene (UHMWPE), high-density polyethylene (HDPE) monofilament, and nylon monofilament.
Manufacturers select different materials based on the intended application and performance requirements of the finished net.
HDPE monofilament is commonly used to produce knotless nets for fish fry farming in coastal waters and inland rivers. Unlike knotted nets, knotless nets have no protruding knots that may rub against or damage fish scales, making them suitable for applications where reducing physical injury to fish is important.
Polypropylene is commonly used for football nets and other sports netting applications.
Polyester multifilament yarn is widely used to manufacture safety nets and protective netting.
UHMWPE yarn can be used to manufacture high-strength knotless nets for deep-sea aquaculture applications.
Single needle bar and double needle bar warp knitting machines can both produce knotless nets. However, the resulting net structures and typical applications are different.
Knotless nets produced on a single needle bar warp knitting machine generally have different appearances on their front and back surfaces.
In contrast, double needle bar warp knitting machines can produce knotless nets with a similar appearance on both sides.
The actual structure depends on the knitting pattern and machine configuration.
When selecting a knotless net making machine, manufacturers should first determine the intended application of the finished net. Important specifications include the raw material, yarn linear density (dtex), net twine thickness, mesh size, mesh count, net width, and required production capacity.
These parameters help determine the appropriate machine configuration and knitting technology. CHENYE can provide customized knotless net making machine configurations.
