[0002]

[Prior art and its problems]

 In recent years, the number of people who enjoy tennis and badminton as a leisure sport has increased rapidly. These people are required to have a gut that is more aesthetically pleasing in addition to performance such as strength and resilience.

As a result of studying in accordance with the above-mentioned demands, the present invention provides a gut that is not only strong but also has a beautiful appearance.

[0004]

[Means for Solving the Problems]

 That is, a first invention of this invention is to use a synthetic resin core thread, a synthetic resin thread arranged around the core thread and having a diameter smaller than that of the core thread, and a core thread thicker than the thin diameter synthetic resin thread. It consists of a core wound yarn made of a thinner and more opaque large diameter synthetic resin yarn, and a synthetic resin coating layer formed on the core winding so as to surround them, and the synthetic resin coating layer was used as the coloring layer. A second invention is to obtain a gut having a structure. A synthetic resin core yarn, a core winding yarn made of a synthetic resin yarn having a diameter smaller than the core yarn arranged around the core yarn, and the core winding yarn. A side winding yarn made of an opaque synthetic resin yarn, which is thicker than the core winding thread and thinner than the core winding thread, and the core winding thread and the side winding thread are surrounded by the side winding thread. A synthetic resin coating layer formed to obtain a gut having a structure in which the synthetic resin coating layer is a colored layer. A.

[0005]

[Action]

 As described above, the present invention provides a gut with an excellent appearance by coloring the synthetic resin coating layer, which is the outermost layer of the gut, to form a colored layer.

That is, when the synthetic resin coating layer covering the upper surface of the thin synthetic resin yarn and the upper surface of the large synthetic resin yarn is used as a coloring layer by dyeing or the like, the large synthetic resin yarn itself is a pigment, For example, since titanium oxide makes it white and opaque, it appears that the hue of this part is different from that of the upper colored layer of the thin synthetic resin thread, and the presence of the large diameter synthetic resin thread is marked by the different hue. It can be a gut with an excellent appearance.

In the present invention, the core yarn may be any synthetic resin yarn such as transparent or opaque nylon or polyolefin, and the opaque synthetic resin yarn may be titanium dioxide, for example, if it is an opaque nylon yarn, It can be obtained by spinning using a molten nylon resin containing an inorganic pigment such as calcium carbonate or an organic pigment, or a molten nylon resin containing a matting agent such as silicic acid anhydride or calcium silicate. Further, as the core winding yarn and the side winding yarn around the core yarn, the same synthetic resin yarn as described above may be used.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment thereof. FIG. 1 is a cross-sectional view showing the configuration of the invention of claim 1, 1 is a core yarn made of, for example, one transparent nylon yarn having a diameter of 0.98 mm. For example, 14 strings of transparent nylon thread 2a having a diameter of 0.162 mm and 6 pieces of opaque nylon thread 2b having a diameter of 0.36 mm are spirally wound to form the cord body 4. Two sets of opaque nylon threads 2b are arranged between the nylon threads 2a at intervals of about 120 °. 5 is a resin coating layer formed by coating a transparent nylon resin on the cord body 4. As is clear from FIG. 1, the portion along the nylon thread 2a is thicker than the portion along the nylon thread 2b. Is formed thick. The resin coating layer 5 was dyed to form a colored layer 6 to obtain a gut having the structure shown in FIG.

In this case, for example, when the nylon thread 2b is made white opaque with titanium dioxide or the like and the resin coating layer 5 is dyed red, the portion of the resin coating layer 5 corresponding to the nylon thread 2b becomes The red color and the white color of the nylon thread 2b overlap and appear pink. In particular, since the resin coating layer 5 has a thin portion corresponding to the nylon thread 2b, it promotes the appearance of a pink color.

FIG. 2 is a sectional view showing the structure of the invention of claim 2, for example, as a core winding thread 2 around a core thread 1 made of one transparent nylon thread having a diameter of 0.98 mm, for example, 0.162. Twenty-four transparent nylon yarns 2a having a diameter of mm are wound, and for example, six opaque nylon yarns having a diameter of 0.36 mm are wound as the side winding yarns 3 on the core winding yarn 2 to form a cord body 4. Is forming. Then, a transparent nylon resin coating layer 5 was provided around the core winding yarn 2 and the side winding yarn 3, and the resin coating layer 5 was dyed to obtain a gut as a colored layer 6. Also in this gut, the portion of the resin coating layer 5 corresponding to the side winding thread 3 made of the opaque nylon thread 2b looks like a hue different from that of the core winding thread 2 as in the case of FIG.

In the above-described embodiment, the number of each of the large diameter opaque nylon thread 2b and the small diameter transparent nylon thread 2a wound as the core winding thread 2 around the core thread 1 of FIG. These arrangements are examples and are not limited to these. For example, three sets of two non-transparent nylon yarns 2b are provided as one set, but one set may be provided at intervals of one line, or two sets or only one set may be provided as two sets. Only one may be provided. The same applies to the side winding yarn 3 on the core winding yarn 2 in FIG.

Further, in the above examples, the colored layer of the gut outermost layer is an example obtained by dyeing the transparent nylon resin coating layer. However, in addition to the transparent nylon resin used for forming the coating layer, Transparent organic pigments such as Pig. It is also possible to mix Orange 43 (Perry none Orange) and form the colored coating layer at once.

Further, in the above embodiment, a transparent nylon resin coating layer is provided around the cord body. However, when this coating layer is a colored layer, the thick and opaque nylon thread 2b portion and other portions are provided. It is not necessarily limited to transparent as long as the hues appear to be different from each other, and a semitransparent to slightly opaque coating layer may be used. The resin coating layer is not limited to the nylon resin coating layer described above.

[Effect of device]

 As described above, the present invention is configured such that a thin synthetic resin thread and an opaque, large diameter synthetic resin thread are wound around a core thread as a core winding thread, or a thin synthetic thread is wound around the core thread. A resin thread is wound as a core thread, and an opaque, large-diameter synthetic resin thread is wound as a side winding thread on this core thread to form a string, and the resin coating layer is colored. By forming a colored layer in the treatment, a racket gut having various hues, having an excellent appearance and strength can be obtained.
