Description

Irregularly arranged multicolor spun yarn and its manufacturing method

The present invention relates to a spun yarn and a method for manufacturing the same, in which a variety of colors are irregularly repeated in a band shape and mixed colors appear at the boundary lines where the colors intersect, and specifically, two or more colors are uniform in the final softening step of the preparation process. The present invention relates to a spun yarn manufactured by mixing a sliver dyed in an irregular order with a cycle and an undyed sliver, and then spinning without further doubling.

In order to express various patterns and colors on the fabric, we used a method of weaving using different color yarns for warp and weft yarns. Therefore, the pattern or color of the fabric by these fabrics is formalized and various changes cannot be made. This mass production could not save the original personality.

Therefore, the yarn itself used as warp and weft yarns has been manufactured with yarns having various colors, or the yarns have been dyed with various colors.

That is, in the spinning process, the dyed and undyed fibers are uniformly mixed to make a good blending of the various colors as a whole, and a number of doublings are made to make melanji yarns, or various colors are applied to the yarn of a skein or cheese state. It has been directly dyed to appear at regular intervals.

However, in the case of Meranji yarn, yarns of various colors are uniformly mixed, and the colors cannot be repeated at regular intervals. In addition, the method of dyeing the yarn in the skein or cheese state, but the color can be crossed in the shape of a band, but a number of dyeing tanks must be provided, and a multi-step process requires a lot of equipment and thus production cost There is a high problem.

Accordingly, the present inventors have studied a method for producing a yarn in which two or more colors are dyed in an irregular order while having a certain cycle in a low-cost and simple method, and as a result, in the last softening process during the spinning process, The above-mentioned color is mixed with irregularly dyed slivers and undyed slivers at a weight ratio of 5:95 to 20:80 at intervals of 3 to 4 cm or less, without further doubling. If the spinning yarn is produced, the present invention was found to be able to achieve the above object, thereby completing the present invention.

Accordingly, it is an object of the present invention to provide a method for producing a yarn in which two or more colors are dyed in an irregular order with a certain period.

Another object of the present invention is to provide a spun yarn produced by the above method.

1 is a side view of yarn produced by the present invention.

2 is a side view of a yarn produced by conventional homogeneous mixing.

Figure 3 is a side view of the yarn produced by cross-dyeing in a yarn state.

In order to achieve the above object, the spinning yarn manufacturing method according to the present invention, the spinning (opening), carding (carding) process, drawing process, spinning (spinning) process and spinning (spinning) process In manufacturing the yarn by the process, in the last softening step of two or three softening process, the slivers and the unstained slivers which are irregularly dyed in two or more colors at a period of 3-4 cm or less It is mixed at a weight ratio of 5: 95-20: 80, and further characterized by not doubling.

The above and other objects, features and advantages of the present invention will become apparent to those skilled in the art from the following detailed description.

Hereinafter, the present invention will be described in more detail.

Spinning yarn according to the present invention various colors are irregularly repeated at regular intervals, and because the mixed color appears at the boundary line between the two colors, it is possible to manufacture a yarn of an unusual appearance, it is possible to produce a variety of fabrics or knitted fabrics using the same The ability to obtain patterns and colors of fabrics and knits in a continuous fashion can show originality. Moreover, the yarns according to the present invention only need to use slivers dyed in various colors, thus reducing the production cost because the process is simple and does not require many devices.

In general, the spinning process for converting fibers into yarns is to open the large chunks of fibers into small chunks, and then comb to separate them one by one, and to open the fiber to some degree in parallel to produce a sliver; A softening step of doubling the sliver to make it uniform; A roughening process which draws the sliver and makes it thinner; Roving made in the spinning process is stretched to the required thickness, and it is composed of a spinning process in which threads are twisted to make a thread. However, the spinning process may be classified into mulle spinning, ring spinning, open-end spinning, etc. according to the last process of forming the yarn, that is, the machine used in the spinning process. In the case of open-end spinning, the spinning process is omitted.

In the manufacturing method of the yarn according to the present invention in the softening process using a sliver prepared by a carding process, at least two or more colors in the last softening process irregularly dyed and a non-dyed slicer The burs are mixed and further not doubled.

In other words, in the last step of the softening process repeated two or three times in the spinning process, the slivers in which two or more colors are dyed at regular intervals are mixed with the undyed slivers without doubling, thus maintaining the color arrangement of the slivers. Therefore, the finally obtained yarns are also irregularly formed with two or more colors having a constant period.

In the manufacturing method, it is preferable to mix the dyed and undyed slivers at a weight ratio of 5:95 to 20:80, which is to maximize the visual effect on the arrangement of various colors at regular intervals, In order to reduce the production cost of the yarn, the dyed sliver has high manufacturing cost.

On the other hand, the dyed slivers may be commercially available or may be directly dyed. The spinning yarn is not spun by only the softening process, but after the softening process, the spinning process is omitted (in the case of open-end spinning) and It is desirable to shorten the cycle of dyed color because it has to go through a square process.

That is, the yarn is manufactured through a continuous drawing process in the spinning process, it is preferable to use a sliver having a color cycle of 3 ~ 4 cm to provide a fabric having a variety of patterns or colors.

On the other hand, for the above purpose, in addition to the color cycle of the sliver, it is preferable to set such that the draw ratio of the spinning process is minimal.

Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited only to these examples.

<Example 1> Burnout (ring spinning)

The draw ratio in each process was selected as 7 for softening process, 10 for spinning process, and 15 for square process, and three colors of red, blue, and green were dyed irregularly at 4cm intervals. The sliver was not fed to the softening step at a weight ratio of 10:90, and then spun yarn was spun and spun to prepare a spun yarn without further doubling.

As a result, a yarn in which red, blue, and green were irregularly repeated in a cycle of 4,200 cm (4 cm × 7 × 10 × 15 = 4200 cm) was obtained.

<Example 2> Cotton spinning (ring spinning)

The stretching ratio in each step was spun in the same manner as in Example 1 except that the softening step was set to 7, the spinning step was set to 7, and the square step was set to 30.

As a result, yarns in which red, blue, and green were repeated irregularly in a cycle of 5,880 cm (4 cm × 7 × 7 × 30) were obtained.

Example 3 Open End Spinning

The draw ratio in each process is set to 7 for the softening process and 82 for the square process, and three colors of red, blue, and green are irregularly dyed and slivers that are not dyed at 4cm intervals. The yarn was fed to the softening process at a weight ratio of 10:90, and spun yarn was manufactured by a spinning process without further doubling.

As a result, yarns in which red, blue, and green were repeated irregularly in a cycle of 2,296 cm (4 cm x 7 x 82) were obtained.

The side view of this yarn is shown in FIG.

Comparative Example 1

The draw ratio in each process was set to 7 for the softening process and 82 for the square process, and the red sliver, the blue sliver, the green sliver and the undyed sliver were supplied to the softening step, and then doubled 16 times. After the spinning process, a yarn was manufactured. As a result, a yarn in which three colors were evenly mixed was obtained. The side view of this yarn is shown in FIG.

Comparative Example 2

The draw ratio in each step was set to 7 for the softening step and 82 for the square step, and an undyed sliver was fed to the softening step, and doubled to spun to obtain a spun yarn. After winding this yarn into a skein, part of the yarn is partially dyed in a red dye bath, another part of the yarn is dyed in a blue dye bath, and then another part is dyed in a green dye bath. Thus, yarns in which red, blue and green colors were dyed regularly were obtained.

The side view of this yarn is shown in FIG.

As described above, the spun yarn spun by the method of the present invention has a unique appearance in which various colors appear irregularly at regular intervals, and mixed colors appear at the boundary line where the two colors intersect. The product can be manufactured.
