1 is a process diagram schematically showing a yarn manufacturing process for artificial grass according to an embodiment of the present invention. This embodiment has been described in terms of three raw materials (A) (B) (N), but this is merely a technique for convenience, and it is clear that the embodiment of the embodiment using four or more raw materials is also possible.

1, the artificial turf yarn according to the present invention is provided with a raw material (A) (B) of white and green synthetic resin raw material in the liquid reactor 10, additionally white and green A raw material N for third synthetic resin raw material having a third color which is not provided is provided.

Here, the reactor 10 maintains a high temperature atmosphere, such as 60 to 150 ° C. higher than room temperature, and the raw materials (A) (B) (N) swell like cotton by a chemical reaction to change their volume.

When the raw materials (A), (B) and (N) swell like cotton independently in the reactor 10, and the chemical reaction proceeds, the corresponding first, second and third seals A1, B1 and N1 respectively. Are drawn to the outside of the reactor (10), respectively. Here, the third yarn N1 preferably has a thickness within 10 to 50% of the diameter of the first and second yarns A1 and B1. For example, the diameter ratios of the yarns A1 (B1) (N1) are 1: 1: 0.1 to 0.5.

This is because when the third synthetic resin raw material (N) exceeds the aforementioned diameter, the final weaved yarn is so thick that it is difficult to weave and the actual touch after implementing the artificial turf is poor.

The yarns A1, B1, and N1 thus drawn out are moved to the plunge machine 20. The envoy machine 20 includes a chamber having a plurality of rollers and a closed structure that are heated during operation, and the drawn yarns A1, B1, and N1 are moved together into one chamber by a roller while being moved into the chamber.

The most important thing in the manufacturing process of the yarn by the present invention is to weave the colors of the synthetic resin yarns A1, B1, and N1 having different colors in the weaving process, respectively. Therefore, when the temperature of the plunge machine 20 becomes higher than necessary in the synthesis process, the synthetic resin yarns A1, B1, and N1 may be fused and mixed, respectively, to achieve a desired color.

And, one embodiment according to the present invention has been described and illustrated to provide a yarn for artificial turf by providing another additional material in addition to the white and green raw materials, but is not limited to this, but two or more different colors It is also possible to use additional materials having. Here, when yarns other than the third yarn N1 are braided, a diameter not exceeding each diameter of the first and second yarns A1 and B1 is most preferred.

In addition, the raw material for the synthetic resin raw material (A1) (B1) (N1) is preferably nylon, polypropylene or polyethylene.

Subsequently, the yarn S1 on which the yarn is completed is wound up and stored in the roller R1.

Figure 2 is a process diagram schematically showing a yarn manufacturing process for artificial turf according to another embodiment of the present invention. Here, in the embodiment according to the present invention, the same components as those in the embodiment of FIG. 1 are used without the same numbering.

2, the artificial turf yarn is provided with raw materials (A) and (B) of synthetic resin raw materials of white and green color in the reactor 10 of the liquid phase, and the white and green are outside the reactor 10. A special function base thread V having a third color is provided. Here, the pre-fabricated yarn V is wound and provided by roller R0.

Here, the reactor 10 is maintained at a high temperature atmosphere, such as 60 to 150 ℃ higher than room temperature, the raw material (A) (B) is swelled like cotton while the volume change by the chemical reaction, respectively. When the raw material (A) (B) swells like cotton and the reaction proceeds, the corresponding yarns A1 and B1 are withdrawn to the outside of the reactor 10.

The drawn yarns A1 and B1 are thus moved to the base yarn V and the copier 20 provided with the roller R0. Plunger 20 is composed of a chamber having a plurality of rollers and a sealed structure that is heated during operation, the drawn yarn (A1) (B1) and the base production chamber (V) is moved into the chamber by a single roller In fact, it is enshrined.

Here, the pre-fabricated yarn (V) used in the present invention is a yarn having a special function, carbon nanofibers for improving durability, antimicrobial fibers to remove shape memory fibers, molds, etc. restored to their original state when the temperature is constant Or it's an anti-treated fiber that keeps dust out. In addition, the pre-fabricated yarn (V) preferably has a different color from the first and second yarns (A1) (B1), it is usually easier to use a smaller diameter than the yarns (A1) (B1) Because. The diameter ratio of the yarns A1 and B1 and the prefabricated yarn is preferably 1: 1: 0.1 to 0.5.

The most important thing in the manufacturing process of the yarn according to the present invention is to weaving the synthetic resin yarns A1 and B1 and the pre-made yarn V each having different colors in the weaving process so that the respective colors are expressed. Therefore, when the temperature of the plunge machine 20 becomes higher than necessary in the synthesis process, the synthetic resin yarns A1 and the pre-made yarn V are fused and mixed, respectively, and thus, a desired color cannot be realized.

And, one embodiment according to the present invention has been described and illustrated to provide a yarn for artificial turf by providing another additional material in addition to the white and green raw materials, but is not limited to this, but two or more different colors It is also possible to use additional materials having.

In addition, the raw material (A1) (B1) for the synthetic resin raw material is preferably nylon, polypropylene, or polyethylene. As described above, the material of the pre-fabricated yarn (V) is carbon nanofiber for improving durability, Antimicrobial fibers for removing shape memory fibers, molds and the like that are restored to their original state, or anti-treatment fibers for preventing dirt from being preferred.

Subsequently, the yarn S2 on which the yarn is completed is wound up and stored in the roller R1.
