Description

[Detailed Description of the Invention] The present invention relates to a penetrating knot of a knotless net in which net legs consisting of triple strands and net legs consisting of 2 strands are mixed and braided for each required number of stitches.

Knotless nets have less net weight than knotted nets,
It is used for purse seines, aquaculture nets, fixed nets, golf nets, etc. because it has characteristics such as low resistance to flowing water, difficulty in adhering to foreign substances, and easy handling because it is not bulky. These knotless nets have conventionally been commonly used as twin-twisted knotless nets, and the knots have also been improved in various ways, and now penetrating knotless nets consisting of complete cross-shaped knots are often used. In addition, in knotless nets, net legs with different diameters, materials, colors, etc. are mixed and braided for each desired mesh, which saves on net material, reduces running water resistance, reduces net weight, and simplifies tailoring work. Efforts are being made to intimidate fish schools.

In recent years, a highly productive manufacturing method capable of continuous operation has been developed for triple-twisted knotless nets, paving the way for their practical application. If the total number of threads in the net legs is the same, the net diameter of the triple-twisted net legs is smaller than that of the two-stranded net legs, which reduces the resistance to flowing water, and the surface of the net legs is more circular and smooth, reducing the possibility of contaminants. It has the advantage of being difficult to attach to.

In the present invention, in a knotless net braided with a mixture of triplet twisted net legs and twin twisted net legs, two strands out of the three strands constituting the triplet twisted net legs are combined into one set, 1 set of remaining 1 strand, and 2
This is a knot obtained by intersecting a total of four sets, with each one strand constituting the child twisted net leg being one set. By braiding mainly 3-strand twisted net legs and 2-strand twisted net legs for each required mesh, it is possible to save net material, reduce the weight of the net, and reduce water flow resistance. Penetration of a knotless net with high knitting strength, which can be used as a force yarn to supplement the strength of the net by braiding the twisted net legs as the main component and the triplicate twisted net legs for each required mesh. It is intended to provide a set of expressions.

Next, an embodiment of the penetrating knots of the knotless net according to this invention will be described based on FIGS. 1, 2, and 3. FIG. 1 shows three strands a, b, c.
A net leg 1 made up of strands F and a net leg 2 made up of two strands f and g are crossed. That is, out of the three strands a, b, and c that make up the net leg 1, a and b are one set, and the remaining strand c is
Of the two strands f and g that constitute another net leg 2, f is one set and g is one set, in total 4
The sets are crossed to form a penetrating set joint 3. To explain the structure of this knot 3, strands a, b, c
After the strands f and g are twisted in the S direction to form the net legs 1 and 2, the aforementioned set A of strands a and b passes over the strand g that constitutes the other party's net leg 2, and then the other party's net. It passes under the strand f that constitutes the leg 2. The strand c constituting the net leg 1 passes below the strand g constituting the counterpart net leg 2, and then passes above the strand f constituting the counterpart net leg 2. Strand f constituting the net leg 2 passes above the set A consisting of strands a and b constituting the counterpart net leg 1, and then passes below the strand c constituting the counterpart net leg 1. Strand g constituting the net leg 2 passes under the pair consisting of strands a and b constituting the other net leg 1,
Next, it passes over the strand c constituting the other party's net leg 1. After each strand set completes crossing in this manner, the strand sets are twisted in the same direction as before crossing to form a net leg. This cross-shaped through-type joint has sufficient joint strength and is a highly practical joint. In addition, in the case shown in Fig. 2, a net leg 4 consisting of three strands a, b, and c and a net leg 5 consisting of two strands f, g are twisted in the Z direction and then intersected. This is a diagram showing a knot 6, and even though the twisting direction of the net legs is essentially different, the knot structure is a cross-shaped through-type knot and is no different from the knot shown in FIG. 1. What is shown in FIG. 3 is a net leg 7 made of three strands a, b, and c and a net leg 8 made of two strands f and g, which are combustible in the S direction and then intersect at a joint 9. shows. To explain the structure of this joint 9, the set A of strands a and b that constitutes the net leg 7 first passes under the strand g that constitutes the other net leg 8, and then the other net leg 8
It passes above the strand f that constitutes the strand f. Strand c constituting the net leg 7 first passes above the strand constituting the counterpart net leg 8, and then passes below the strand f constituting the counterpart net leg 8. The strand f that constitutes the net leg 8 first passes under the group A of strands a and b that constitutes the other net leg 7,
Next, it passes over the strand c constituting the opponent net leg 7. The strand g that makes up the net leg 8 first passes above the set A of strands a and b that makes up the net leg 7, and then passes under the strand c that makes up the net leg 7. After each set of strands has completed crossing, the strands are combustible in the same direction as before crossing to form the net legs. In this invention, the diameter of the strands constituting the legs of the triple twist net may be different from the diameter of the strands constituting the legs of the twin twist net.
Further, each strand may be a monofilament, or may be a yarn-like product, such as a multifilament made by pulling together a few twisted yarns and adding a first twist to them, and then adding a medium twist to the multifilaments.

As mentioned above, the penetrating knots of the knotless net according to this invention constitute triple-twisted net legs in a knotless net that is braided with a mixture of triple-twisted net legs and twin-twisted net legs. Out of the three strands, two strands are made into one set, and the remaining one strand is made into sets 1 and 2.
1 strand each composing the child twisted net legs
One of the two sets of strands constituting one net leg as a set crosses the two sets of strands constituting the other net leg first on the upper side and then on the lower side, and the remaining one set crosses the two sets of strands constituting the other net leg. This is a cross-shaped through-type knot with high knot strength, which is made to intersect the two sets of strands that make up the strands, first on the lower side and then on the upper side.
