Description

fancy yarn

The following disclosure generally relates to a fancy yarn composed of yarn lines and decorative fibers interlaced with the yarn lines.

In order to achieve the purpose of exerting a decorative effect on textiles or knitted fabrics, periodic or non-periodic changes such as loops or slugs may be given to the yarn in advance. Yarns imparting this variation are often called fancy yarns. So far, we have proposed most fancy yarns.

There is no certain method for producing fancy yarns. In some cases, changes are given during the weaving step. In other cases, after the yarn is made into yarn through the weaving steps, the yarn is processed to give changes. In the case of processing, one yarn line may be processed, and other yarn lines may be interlaced with one yarn line.

The following exemplary embodiments will be described with reference to the accompanying drawings. In Figures 4 to 10 illustrating the manufacturing method, the yarn lines are roughly depicted as traveling from bottom to top, or from right to left, but these directions are only examples, and can also be implemented by switching up and down or left and right as appropriate. Alternatively, it may be entirely or partially inclined obliquely.

Referring mainly to Figure 1 , the fancy yarn 10 of this embodiment is roughly composed of yarn strips 1 (3) and decoration D. The decoration D is composed of decorative fibers. For example, as can be seen with reference to FIGS. 3A to 3C , the decoration D is formed by interlacing the decorative fibers 5 c with the yarn strips 1 ( 3 ).

The yarn lines 1(3) and decorative fibers 5c are respectively made of synthetic fibers such as polyester or polyamide, semi-synthetic fibers such as acetate, rayon or Cupra, and kapok. It is composed of any one of natural fibers such as linen, wool or silk, or a mixture of two or more fibers selected from the above-mentioned fibers. The fibers constituting the yarn lines 1, 3, and the decorative fibers 5c respectively may be the same or different in terms of thickness, color, luster, material, and other characteristics.

The yarn line 1 (3) is a bundle of fibers running roughly along the main direction M, and may be only the main yarn line 1, or may also include other auxiliary yarn lines 3. Of course, other yarn lines can also be included. The fibers constituting the yarn lines are integrally false-twisted around the main direction M as shown in Figure 2A, or are integrally twisted around the main direction M as shown in Figure 2B. In these drawings, although only two main fibers 1fa and 1fb are depicted, in fact a large number of fibers are actually twisted or falsely twisted to form the yarn line 1(3).

The decorative D system consists of cutting yarn lines of the same or different types as the main yarn lines into shorter decorative fibers 5c. The decorative fibers 5c are interlaced with the fibers constituting the yarn line 1 (3) and are fixed to the fibers. As mentioned above, the decorative fiber 5c can be the same as or different from the yarn strip 1 (3) in terms of thickness, color, luster, material (nylon, polyester, etc.) and other characteristics. Through these combinations, countless changes in decorative effects can be produced.

Referring back to Figure 1, the decoration D may be discontinuous along the main direction M on the fancy yarn 10, and be limited to specific widths _S1 , _S2 ... respectively. The widths S ₁ , S ₂ ... may be approximately the same as each other, or may be different from each other. Moreover, the distances V ₁ and V ₂ between each other may be approximately the same as each other (that is, the decorative D systems are equally spaced in the main direction M), or they may be different from each other (that is, the decorative D systems are equally spaced in the main direction M) non-equal intervals). The widths S ₁ , S ₂ ... or the intervals V ₁ , V ₂ ... can be arbitrarily increased or decreased according to the manufacturing conditions as will be known from the following description. The combination of these can also change the decorative effect.

Mainly referring to Figure 2A, although only two decorative fibers 5ca and 5cb are illustrated here, as for any decorative fiber, although the parts other than its two ends 5e are interlaced with the main fibers 1fa and 1fb, only the two ends 5e and its vicinity They escape from the main fibers 1fa and 1fb toward the outside and protrude, that is, fluffing. Even in the case of false twisting, the main fibers 1fa and 1fb are interlaced with each other, and the decorative fibers 5c are interlaced throughout this structure, so the decorative fibers 5c are not easy to fall off. Of course, as shown in FIG. 2B , in the case of real twisting, since it is limited to the inside of the real twisting structure, it is more difficult for the decorative fiber 5c to fall off. Decorative fiber 5c is fluffed to form a fluff-like appearance, which contributes to decorative properties. However, unlike fluff, it will not fall off easily. The appearance of fancy yarn 10 will not be affected by the weaving or knitting process. Therefore, the fancy yarn 10 series can give stable decorative properties to textiles or knitted fabrics.

Both ends 5e and their vicinity escape from the main fiber toward the outside as described above. This part is specifically responsible for decorating the appearance of D, and is an important element of the decorative effect obtained by this implementation type. This length can also be increased or decreased depending on manufacturing conditions. However, it is not limited that all the ends 5e escape outward, and a part thereof may be buried in the main fiber.

Of course, all the decorative D series can be the same in terms of thickness, color, gloss, material (nylon, polyester, etc.) and other characteristics, or they can also be different from each other. Through these combinations, countless changes in decorative effects can be produced.

The fancy yarn 10 can be produced by, for example, the process described below.

Referring mainly to FIG. 4 , generally, the main yarn strip 1 is sent out from the main yarn supply creel 11 , passes through the twisting device 23 , and is wound by the winder 31 . In the converging area 17 in the middle, the decorative fiber 5c is supplied from the side, for example, merges into the main yarn line 1, and is sent to the twisting device 23 together with the main yarn line 1. In order to guide the main yarn line 1 in the above manner, yarn line guides such as rings or rollers can be suitably provided.

The decorative fiber 5c is sent out from the decorative yarn creel 15 in the form of, for example, a yarn line 5 belonging to a long yarn line that has not been cut, and is intermittently cut by the cutting machine 21, and is then sprayed The nozzle 19 supplies the air to the confluence area 17 along the air flow A1. Alternatively, the decorative fibers 5c that have been cut beforehand may be stored in advance and be intermittently discharged toward the confluence area 17 in small amounts by the air flow A1. The air flow A1 can be generated by a blower, compressor, etc. connected to the injection nozzle 19 .

The decorative fibers 5c follow the air flow A1 to reach the confluence area 17, where they merge with the main yarn line 1. At this time, the main yarn line 1 will capture the decorative fiber 5c by the vibration accompanying its progress or by the vibration caused by the air flow A1. At this time, as shown in FIG. 3A , the decorative fiber 5c only follows the main yarn line 1, or is lightly wound.

The auxiliary yarn line 3 is sent out from the auxiliary yarn supply creel 13 and joins the main yarn line 1 at a point upstream or downstream of the confluence area 17 . Figure 4 shows an example in which the main yarn line 1 is converged downstream of the converging area 17. According to this example, the auxiliary yarn line 3 follows the main yarn line 1 in a manner to cover the decorative fiber 5c. This will generally enhance the effect of introducing the decorative fiber 5c into the yarn lines 1, 3.

In the example shown in Figure 4, although the main yarn lines, auxiliary yarn lines, and decorative yarn lines are sent out from three yarn supply creels respectively, the yarn supply creels can also be added to send out two or more main yarn lines or Two or more secondary yarn lines. Furthermore, more than two decorative yarn lines can also be used. In this case, a combination of a decorative yarn line creel, a jet nozzle, a cutting machine, and a confluence area is added. As mentioned above, two or more decorative yarn lines can be made into different thicknesses, different colors, or different glosses.

The main yarn line 1 travels together with the decorative fiber 5c and the auxiliary yarn line 3 in the twisting device 23, and is twisted by the twisting device 23. In the case of performing false twisting, the twisting device 23 may use a swirling nozzle that performs false twisting on the yarn line by swirling air flow, for example.

The twisting device 23 is specially used to prevent the decorative fiber 5c from falling off, and it is not necessarily necessary to wind the yarn lines 1 and 3. The appearance of the yarn lines 1, 3 and the decorative fiber 5c passing through the twisting device 23 is shown in Figure 3B.

Referring back to Figure 4, in order to enhance the interlacing of the yarn lines 1, 3 and the decorative fibers 5c that merge with each other, an interleaving device 25 can also be used. The staggering device 25 may include, for example, a water imparting guide 27 and a staggering nozzle 29 .

The water supply guide 27 is a yarn line guide equipped with a nozzle capable of injecting a small amount of water onto the yarn line. Alternatively, the staggered nozzle 29 may be provided with a water nozzle instead of using the water supply guide 27 . By adding a small amount of water to the yarn lines, the interlacing of the yarn lines 1, 3 and the decorative fiber 5c can be further enhanced.

The staggered nozzle 29 is a conventional staggered nozzle such as an air nozzle, and is a device that uses a blower or the like to eject a relatively high-speed air flow toward the yarn line passing through the nozzle. The air flow generates higher-speed turbulence around the yarn lines, and the yarn lines passing through the nozzle are interlaced.

By using the interlacing device 25, the yarn lines 1 and 3 are wound with each other and interlaced with the decorative fiber 5c to be firmly entangled with each other, so that the fancy yarn 10 as shown in FIG. 3C can be obtained.

In the above description, the example of using staggered nozzles has been described. However, staggered nozzles may be used instead, or a yarn processing device such as a hollow spindle or a combination of a friction twisting device and a heating device may be used. Furthermore, heating or bonding may be used instead of or in addition to the processing means of the yarn lines. Examples of the heating means include heaters, lasers, and ultrasonic wave generators.

Furthermore, in the above description, although the example in which false twisting is performed on the yarn lines is explained, real twisting may be used instead of false twisting. In this case, as illustrated in FIG. 5 , for example, a real twisting device 23 b is used instead of the twisting device 23 . The actual twisting device 23b is, for example, a combination of a twisting machine and a spindle. In this case, the spindle system It also functions as a winding machine. By solid twisting, the decorative fiber 5c can of course be stably wound in the yarn lines 1 and 3, and the yarn lines 1 and 3 can be wound more stably. During the actual twisting, since the decorative fiber 5c can be stably wound around the main yarn line 1, the step of interlacing by the interlacing device 25 can also be omitted.

Furthermore, in this example, the yarn line guide 23a may be disposed downstream of the confluence area 17 and upstream of the actual twisting device 23b. The yarn line guide 23a only has the function of specifically guiding the auxiliary yarn lines 3 to the main yarn line 1 and the decorative yarn line 5, but may also be configured to wind or process the yarn lines. .

In the step of making the decorative fiber 5c merge into the yarn lines 1 and 3, the yarn lines 1 and 3 can also be wound to promote the capture of the decorative fiber 5c by the yarn lines 1 and 3. This will significantly reduce the chance of the decorative fiber 5c being inadvertently detached from the yarn lines 1, 3 during the converging step. The controllability of the intervals V ₁ , V ₂ ... between adjacent decorations D will inevitably be significantly improved.

Referring to, for example, FIG. 6 , the yarn supply creels 11 and 13 are not essential, but are arranged, for example, axially symmetrically, and supply the main yarn line 1 and the auxiliary yarn line 3 toward the confluence area 17 respectively. The yarn lines 1 and 3 are Convergence here. The decorative fibers 5 c are fed, for example vertically, along the axis of travel of the yarn lines 1 , 3 towards the confluence area 17 . For supplying, a combination of the spray nozzle 19 and the cutting machine 21 can be used as in the above example, but this is not essential.

On the other hand, the twisting device 23 arranged downstream of the converging area 17 is, for example, a swirling nozzle as described above, and swirls the converging yarn lines 1 and 3 . The convolution also propagates to the confluence area 17, that is, the decorative fiber 5c is supplied to the convoluted yarn lines 1, 3, captured in the yarn lines 1, 3, and thus entangled and introduced into the yarn lines 1, 3.

In order to promote the decorative fiber 5c to be wound around the yarn lines 1 and 3, the guide 39 illustrated in Figure 7 can be used. The guide 39 is opened at one end (usually the lower end), and the introduced yarn lines 1 and 3 are It is spit out with decorative fiber 5c. The inside of the guide 39 is an internal space extending along the axial direction, and the internal space is dimensioned to allow the yarn lines 1 and 3 to rotate around the axial direction to a certain extent. The guide 39 may further include, for example, openings 41 and 43 on its side surfaces, through which the yarn lines 1 and 3 are respectively introduced into the inside.

The decorative fiber 5c is introduced from the upper end of the guide 39, guided to the yarn lines 1 and 3, and wound around and introduced to the wound yarn lines 1 and 3.

Referring back to FIG. 6 , the yarn lines 1 and 3 and the decorative fibers 5 c that merge with each other are twisted and interlaced by the twisting device 23 . Similar to the above method, the interleaving device 25 can also be used to further enhance the interleaving, and of course the interleaving device 25 can also be omitted. The fancy yarn 10 produced by this method is wound by the winder 31.

Alternatively, the decorative fiber 5c can be interlaced with the yarn line 1 by winding the yarn line when it is detached from the yarn tube.

Referring illustratively to Figure 8, bobbins 11, 13 are used, for example in a coaxial arrangement, or suitably offset. A centering guide 16 for guiding the main yarn line 1 to the center may also be provided between the yarn bobbins 11 and 13 . Yarn lines 1 and 3 are wound around the bobbins 11 and 13 respectively. As the bobbins 11 and 13 rotate around the axes respectively, the yarn lines 1 and 3 are fed out while revolving around the respective axes.

The decorative fiber 5c is supplied to the area clamped by the centering guide 16 intermittently, for example. In this area, the main yarn line 1 is further wound, and the decorative fiber 5c is drawn into the main yarn line 1 and wound around the main yarn line 1 .

In order to wind the decorative fiber 5c around the main yarn line 1 more reliably, the guide 17 illustrated in Figure 9 can be used. The guide 17 is, for example, a substantially hollow tube, and the inside thereof is a cavity 17h extending in the axial direction. For example, openings 17t are provided on its upper and lower sides, and the main yarn line 1 passes through the openings. 17t is guided to the bobbin 13. Furthermore, the cavity 17h allows the decorative fiber 5c supplied from the injection nozzle 19 to pass therethrough. The guide 17 can also be connected to the injection nozzle 19, or be integrated.

The cavity 17h is dimensioned in such a way that the main yarn strip 1 can be wound around its axis. The main yarn line 1 wound just below the guide member 17 can also be wound in the cavity 17h after passing through the opening 17t on the lower side. By being entangled in this winding, the decorative fiber 5c is reliably wound around the main yarn line 1.

At least the bobbin 13 can be a bobbin used in a conventional coating machine and combined with a hollow spindle. The main yarn line 1 accompanied by the decorative fiber 5c is introduced into the hollow spindle, and the auxiliary yarn line 3 supplied from the yarn tube 13 is wound around the main yarn line 1 while being wound around. The decorative fiber 5c is introduced into the yarn lines 1 and 3, is reliably entangled with the yarn lines, and is truly twisted together with the yarn lines 1 and 3, thereby producing the fancy yarn 10.

The size or width _S1 , _S2 ... of the decoration D formed by the decorative fiber 5c can be freely changed according to the length of the decorative yarn line 5 cut off, and the intervals _V1 , V between adjacent decorations D ₂ ...can also be freely changed according to the speed of the yarn supply line 1 and the distance between the decorative yarn lines 5 to be cut. Of course, the size and spacing can also be changed according to each decoration D. Furthermore, as mentioned above, since two or more decorative yarn lines can also be used, different colors or glosses can be made according to each decoration D, for example.

As can be seen from the above description, the decorations D are each formed into a structure that protrudes outward from the yarn lines like fluff, but unlike the fluff, it is not easy to fall off. Unlike ribbons, decoration D is not continuous, but can be separated at equal or unequal intervals. This structure has characteristics not seen in fancy yarns produced by conventional manufacturing methods. The decorative effect has countless changes depending on the thickness, color, gloss, material, etc. of the fiber. That is to say, according to this embodiment, the fancy yarn 10 can be used to produce a decorative effect different from that of the conventional fancy yarns, and of course the fabrics woven or knitted using the fancy yarns can produce the conventional decorative effects. Unprecedented decorative effect. This embodiment provides novel decorative changes to yarn and cloth technology.

Although several implementation forms are described, modifications or transformations of the implementation forms can also be made based on the above disclosure.
