More particularly, the present invention relates to a light shielding film manufacturing method for fabricating a light shielding net with improved light shielding efficiency by changing a connection structure between fibers forming a light shielding net.
In the conventional light shielding net, a synthetic fiber monofilament yarn is fed in the longitudinal direction and a synthetic fiber cloth tape yarn is wound in a jigging direction So that both ends of the embroidery yarn are bound to the circular yarn of the binding yarn.
A variety of techniques have been proposed to improve the light shielding performance and the binding force of such a light shielding net. Hereinafter, the proposed prior arts will be described below.
Korean Patent Laid-Open No. 10-2006-0082022 discloses a reinforced light shielding net and a manufacturing apparatus of the same. The reinforced light shielding net and the manufacturing apparatus of the same disclosed in Japanese Laid-Open Patent Publication No. 10-2006-0082022 are made of a synthetic monofilament yarn and a synthetic monofilament The present invention relates to a reinforced light shielding net and a manufacturing apparatus for the reinforced light shielding net so that the binding yarn, the insertion yarn and the reinforcing insertion yarn are organically bound so as not to be loosened at the binding portion. More specifically, the embroidery yarn is composed of a binding yarn made of synthetic resin monofilament yarn and a synthetic yarn made of synthetic resin tape yarn, the yarn having a certain size and arranged in a vertical direction. The embroidery yarn is supplied in zigzag form to three binding yarns, In the known light shielding net linked to the circular rings of both binding yarns, a reinforcing insertion yarn made of a synthetic resin monofilament yarn is inserted between two lines of binding yarns, and the reinforcing insertion yarn is supplied in a zigzag shape, And a reinforcement inserting yarn bundled at predetermined intervals in a circular ring formed on the warp yarns and arranged in an oblique direction between the bundles. As a result, it is possible to knit the light shielding net into which the reinforcing insert is inserted smoothly, thereby obtaining a stable light shielding net that does not cause loosening at the bottom when cutting the binding yarn, and thus provides a durable, We can do it.
Another example of the prior art is disclosed in Korean Patent Laid-Open No. 10-2013-0044490, which relates to a canopy net that minimizes shape deformation even when subjected to an external impact, maintains durability as a whole, and can not be disassembled at the time of disconnection. Specifically, the conventional art has a reference yarn arranged in parallel to a plurality of yarns, a film yarn that is woven in a staggered manner and staggered with each of reference yarns, and a plurality of reference yarns adjacent to one reference yarn And a reinforcing portion that is repeatedly wound around the reference yarn along a longitudinal direction of the reference yarn from a connecting portion extending from the connecting portion to the reference yarn through the reference yarn is repeatedly woven. As a result, it is possible to prevent the malfunction of the machine or the damage of the worker during the weaving process from the weaving structure including the main yarn and the reference yarn as the connecting yarn and the reinforcing yarn, Even if the reference yarn or the film yarn is cut off by carelessness, the problem of disassembly of the pre-fabricated weaving structure is not caused at all.
However, the above-mentioned prior arts only disclose a structure for increasing the binding force of the light shielding net, but do not disclose a method for increasing the light shielding efficiency.

The description of the general contents of known configurations in this specification can be omitted in order not to obscure the gist of the present invention.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
First, a process of a method of manufacturing a light shielding net with improved light-shielding efficiency according to an embodiment of the present invention will be described below with reference to Figs. 1 to 2 in comparison with the prior art.
FIG. 1 is a schematic view showing a process of a conventional light shielding film manufacturing method, and FIG. 2 is a schematic view showing a process of a light shielding net manufacturing method with improved light shielding efficiency according to an embodiment of the present invention.
As shown in FIG. 1, in the conventional light shielding film manufacturing method, a path through which reference yarn is supplied in the longitudinal direction is formed, and a total of nine reference yarn supplying paths may be provided. Through this supply path, a total of four reference yarns can be formed, and the reference yarns positioned on both sides of the four reference yarns are bound to each other in a zigzag shape, thereby allowing a light shielding net to be manufactured.
Specifically, in the conventional shading film manufacturing process shown in FIG. 1 for the first time period, the first reference yarn supplied through the third path is bonded to the first reference yarn and then the first reference yarn positioned on the first path . Then, during the second time, the four reference yarns extend in the longitudinal direction, the first reference yarn is positioned on the seventh reference yarn on the seventh path for the third time after the second time, The fourth reference yarn is positioned on the second reference yarn. And four reference lines are extended in the longitudinal direction as in the second time period for the fourth time period after the third time period. The above process is repeated to finally produce a light shielding net.
In contrast, in the method for fabricating a light shielding net with improved light-shielding efficiency according to an embodiment of the present invention shown in FIG. 2, basically a reference yarn supply path consisting of first to ninth paths, The light shielding film is manufactured by using a warp knitting machine having a feed path for the feed yarn as one path unit.
A method of fabricating a light shielding net with improved light shielding efficiency according to an exemplary embodiment of the present invention will now be described in detail with reference to FIGS. 1 and 2, wherein a first reference yarn is formed in a first path from a first path to a third path during a first time, A second reference yarn is formed, a third reference yarn is formed in the fifth path from the seventh path, and a fourth reference yarn is formed in the seventh path to the ninth path.
Next, a second step is performed to bind the reference yarns to the reference yarns of the first path and the reference yarns of the third path sequentially corresponding to the first reference yarn during the first time.
Next, a third step of extending the first reference yarn to the fourth reference yarn in the direction of the reference yarn supply path along the third path is performed during a predetermined time after the first time.
Next, a fourth step is performed so that the first reference yarn to the fourth reference yarn return to the initial paths respectively for the second time after the lapse of the predetermined time.
Next, during the second time, the fifth step is performed in such a manner that the corresponding posture is sequentially bound to the reference posture of the ninth route and the reference posture of the seventh route in correspondence with the fourth reference posture.
Finally, a sixth step of sequentially repeating the first to fifth steps is performed.
The method of manufacturing a light shielding net with improved light-shielding efficiency according to an embodiment of the present invention for performing such a series of processes is different from the conventional method of manufacturing a light shielding net by the method of arranging a reference yarn, . That is, unlike the conventional shading network manufacturing method, the order of formation (supply) of the first to fourth reference yarns is changed from the first path to the third path in the third path instead of the first path, The flow chart was changed from the first path to the third path in the third path instead of the first path with respect to the first reference path. Also, the fourth reference yarn was changed from the ninth to the seventh, not the ninth, from the seventh to the ninth.
Specifically, during a predetermined period of time in the third step, the presenter shifts the second reference yarn and the third reference yarn sequentially in the fourth reference yarn direction. That is, after the first master is connected to the first master, the second master and the third master sequentially pass through the fourth master to bind the master.
Further, it is preferable that the first to fourth reference yarns have the same brightness and size, and the brightness is lower than that of the reference yarn. That is, it is preferable that the fiber filament to be a reference yarn has a color of a dark color having a low lightness as compared with a color filter, and a color of a light color, while a filament has a light color. Also, it is preferable that the first to fourth reference yarns have the same size and thickness.
Further, after the end of the sixth step, the first to sixth steps may be performed again after shifting to the other reference yarn supplying path neighboring the first path or the ninth path in the reference yarn supplying path. That is, after the first and second reference threads and the fourth reference threads are bound together through one path unit to which the first to sixth steps are applied, the other reference threads adjacent to the first reference thread and the fourth reference thread are additionally applied (SHIFT to the left or right) to perform an expansion process for forming a light shielding net, thereby finally fabricating a light shielding net. In addition, after applying another reference yarn neighboring to the first reference yarn and the fourth reference yarn, the same process is repeatedly performed for another reference yarn neighboring another reference yarn.
In addition, the light shielding net can be finally manufactured through the shifting process and the repetitive processes of the first to sixth steps. The light shielding net fabricated through the different method of the present invention can be manufactured by a conventional method The light shielding efficiency is higher than that of the manufactured light-shielding net and the durability of the fastened state is improved. Shading efficiency and tightening durability will be described below with reference to Figs. 3 to 4. Fig.
FIG. 3 is a photograph showing a structure of a light shielding net fabricated according to a conventional light shielding film manufacturing method, and FIG. 4 is a photograph showing the structure of a light shielding netting fabricated according to an embodiment of the present invention.
As shown in FIG. 3, in the case of the light-shielding film manufactured according to the conventional light-shielding film manufacturing method, the light-shielding film is merely focused on only the reference yarn and the reverse yarn. In other words, it can be seen that the center of gravity is connected to the center of gravity, and the gravity of the gravity is concentrated on the reference gravity due to this reason. Also, from the viewpoint of the binding force (durability), an appropriate binding force is required and required for the entire light shielding net. However, the binding force is concentrated only on the reference yarn, and consequently, the binding force of the overall lightening net is low.
On the contrary, in the case of the light-shielding network according to the manufacturing method according to the embodiment of the present invention shown in FIG. 4, the working yarn is basically dispersed relatively uniformly without being intensively bonded to the reference yarn, The light can be shaded uniformly, thereby increasing the overall shading efficiency.
In addition, since it is not a binding method concentrated on one place, the reference book and the serving company are uniformly distributed throughout the entire lightening network, so that it is possible to have a binding force of a certain level or more in the entire lightening network portion as a whole.
Further, as shown in Fig. 4, the master yarn passes through the first circular yarn formed by the first reference yarn and the second reference yarn adjacent thereto, and the second circular yarn formed by the third reference yarn and the neighboring fourth reference yarn The light is transmitted through the first and second circular rings four times or more. In other words, compared with the conventional light-shielding net manufacturing method shown in FIG. 3 (in which two or three switches are transferred on the average), the structure of the light-shielding net according to the method of manufacturing the light- The light shielding efficiency and the binding force can be improved with respect to the entire light shielding net because the light shielding structure has a structure in which the light shielding member passes an average of four times or more.
It is to be understood that the above-described embodiments are provided to facilitate understanding of the present invention, and do not limit the scope of the present invention, and it is to be understood that various modifications may be made within the scope of the present invention. Accordingly, the technical protection scope of the present invention should be determined by the technical idea of the claims, and the technical protection scope of the present invention is not limited to the literary description of the claims, To the invention of the invention.
