Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative yarn used in the field of clothing such as woven and knitted fabrics and various decorative fabrics, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, decorative threads have been widely used as one of methods for providing a decorative effect to cloth such as woven and knitted fabrics. For these decorative yarns, a method of twisting yarns of different colors and raw materials, a method of varying the supply amount of yarns of different colors and raw materials with a decorative twisting machine to make wall twists, and pattern dyeing of yarns It is produced by a method called space dicing in which the dye is partially applied and dyed for practical use.

[0003]

However, the decorative yarn made by twisting yarns of different colors and different raw materials is a monotonous yarn. Also, when twisting yarns of different colors and raw materials with different supply amounts, it is necessary to increase the change rate of the supply amount in order to emphasize the color difference. The yarn tends to be loosened, and the portion is displaced during running in a later process or is hardened in one place. Therefore, it is necessary to strengthen the twist. If the twist is increased, the yarn becomes hard and the productivity is reduced. Further, in the case of yarn dyeing such as space dyeing, a special dyeing method is required, resulting in low productivity and high cost.

The present invention solves such a conventional problem,
An object of the present invention is to provide a decorative yarn which is rich in decorativeness and has good processability, and a method for producing the decorative yarn with high productivity.

[0005]

According to the present invention, a plurality of yarns (A, B, etc.) of the same color or different colors of similar darkness and different colors or colors from the yarns (A, B, etc.). Of a plurality of yarns (D, E, etc.) of the same color or different colors of the same depth, and the yarns (A, B, etc.) and the yarns (D, E, etc.) The part twisted in a state where the constituent yarns are arranged adjacent to each other and the part twisted in a state where the constituent yarns are alternately arranged alternate in the longitudinal direction at arbitrary intervals. And a plurality of yarns (A, B, etc.) of the same color or different colors of the same depth and different colors from the yarns (A, B, etc.) When twisting a plurality of yarns (D, E, etc.) of the same color or different colors of the same color depth, the yarns (A, B, etc.) and the yarns (D, E) are processed. etc)
A method for producing a decorative yarn, characterized in that twisting is carried out while changing the constituent yarns adjacent to each other and the arrangement in which the respective constituent yarns are alternately arranged at arbitrary time intervals. The above-mentioned problems are solved by.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an example of the decorative thread of the present invention.
In the figure, (A, B) are two yarns of the same color, (D,
E) is two yarns of the same color different from the yarns (A, B), and the portion indicated by H of the decorative yarn is composed of the yarns (A, B) and the yarns (D, E). Like AB and DE, it is a part in which each constituent yarn is twisted in a state where they are arranged adjacent to each other.
Further, the portion indicated by I is a portion in which the constituent yarns of the yarns (A, B) and the yarns (D, E) are twisted in a state in which they are arranged alternately like ADBE, Since the I portion and the I portion are alternately present along the longitudinal direction of the decorative thread at arbitrary intervals, the decorative thread is highly decorative.

The yarns (A, B) and the yarns (D, E) are A
And B and D and E are not limited to the same color, but yarns having different colors and similar color strength may be used.
B) and the yarns (D, E) must be different in color or color depth. In addition, yarn (A, B) and yarn (D, E)
May be a yarn that becomes different in color by dyeing after being made into a decorative yarn or has a different color depth. Further, spun yarns or filaments of natural fibers or synthetic fibers may be used, and as long as the yarns can be twisted, they may have different thicknesses. Rather, the combination of the thick yarn and the thin yarn changes the unevenness of the wall yarns and becomes a decorative yarn rich in decorativeness.

The number of yarns (A, B) and the number of yarns (D, E) are not limited to two each. The larger the number, the more complicated the arrangement of yarns becomes, but the decorative effect of the decorative yarn is further emphasized. If the difference in color type or color density is different among all the yarns constituting the decorative yarn, the effect is small. If the total number of constituents is about 4, the grouping of the difference in color type or color density is effective even if it is 3 groups, but it should be 2 groups with large difference in color type or color density. Is the most effective.

Next, a method of manufacturing the decorative yarn of the present invention will be described. FIG. 3 is a side view showing an example of an apparatus used for manufacturing the decorative yarn of the present invention, and FIG. 4 is an explanatory view showing a method for changing the arrangement of yarns. In FIGS. 3 and 4, 1 is a feed roller,
2 is a traverse device, 3 is a yarn guide attached to the traverse device, 4 is a twisting guide, and G is a twisted decorative yarn. The feed roller 1 is a roller that grips the yarns A, B, D and E and supplies them to a twisting device (not shown) at a constant speed. The traverse device 2 uses the specific yarn B to guide the yarn guide 3
The yarns are reciprocally moved through a certain distance to the left and right to change the arrangement of the yarns. The reciprocating motion at regular intervals may be performed by combining a motor, a solenoid valve, an electric signal generator, etc. by a known crank system, a fluid cylinder system, or the like. The twisting guide 4 is a ring twisting yarn, a flyer twisting yarn, or the like, which replaces the snell wire between the twisting device and the feed roller.

The yarns A, B, D and E are arranged as shown in FIG. 4, supplied to the feed roller 1 and fed to the twisting device in the aligned state to be twisted. In this case, the yarn B is guided by the yarn guide 3 attached to the traverse device 2.
When supplying the yarns A, B, D, E to the feed roller 1, if the yarn intervals of the yarns A, B, D, E are too narrow, the yarn order may change. It is preferable to apply a proper tension to the guides to keep the gap.

In the twisting process, when the twisting spread point is in the vicinity of the snell wire, the spiral snell wire used in the conventional twisting machine has a circular inner side so that the yarns are easily bundled and the order is Since it fluctuates, it is preferable to arrange the yarns linearly with the guide 4 having a linear contact surface and twist the yarns.

When the yarns A, B, D and E are composed of four yarns as shown in FIG. 4, the traverse device 2 is arranged in the order of ABDE at the position a and is supplied by the feed roller 1. When twisted by twisting,
Twisted yarn G in which yarns A and B of the same color are arranged in the order of BDE and yarns D and E of different colors from the yarns A and B are arranged.
Becomes Next, when the traverse device 2 slides to the right to the position of B, the yarn B moves and the arrangement is changed in the order of ADBE, and the twisted yarn G is twisted in the order of ADBE as shown in Part I of FIG. Thus, the twisted yarn G is formed by alternately arranging the yarns of different colors without arranging the yarns of the same color.

Further, as shown in FIG. 5, when the yarns are composed of six yarns, the yarns A, B, C, D, E and F are arranged in the order of ABDEFC when the traverse device 2 is at the position a. When the yarn is supplied to the feed roller 1 and processed for twisting, the yarns A, B and C of the same color are arranged in the order of ABDEFC as shown in the portion J of FIG. 2, and the yarns A, B and C are different in color. The twisted yarn G has a configuration in which the yarns D, E, and F are arranged side by side. Next, when the traverse device 2 slides to the right to the position of B, the yarns B and F move and the arrangement is changed in the order of ADBECF, and the twisted yarn G is arranged in the order of ADBECF as shown in part K of FIG. Is a twisted yarn G in which yarns of the same color are not arranged and yarns of different colors are alternately arranged.

The length and randomness of the H or J portion, the I or K portion are determined by the conditions such as the sliding frequency of the traverse device 2, and the length of the color changing portion is designed according to the design of the fabric when it is formed. It may be set as appropriate, and its control is performed by a length conversion signal calculated from the rotation speed of a rotating body such as the feed roller 1 or a timer.
