Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a string-like special yarn knitted by warp knitting.

(Prior Art) In recent years, various types of yarns have been tested for use in summer sweaters, decorative fabrics, etc., and handicraft yarns are one of them. Traditionally, this type of handicraft yarn has been used for textiles. Knitted fabrics, plaited fabrics, etc. are used, such as thin R] J-tegue-shaped fabrics and various braided fabrics.As for knitted fabrics, weft knitted fabrics include braided cords knitted with special circular knitting machines. Furthermore, in warp knitted fabrics, flat tape yarns are known that are a combination of insertion knitting or atlas knitting and chain knitting.

However, since the narrow tape-like knitted fabric is a woven fabric, the required elongation in the longitudinal direction of the tape is not 1=1, which results in a hard texture for sweaters, etc. using this fabric. There are also problems such as the need for special LLI11 machines. In addition to the disadvantage of having a hard texture, braided cord also has the problem of low productivity and high cost. In addition, knitted cord is commonly known as lilyan, but since it is a weft knitted material, the knitting yarn is unwoven and frayed, and a special circular knitting machine with a diameter of 20 mm or less is required. In addition, it also had the disadvantage that the stitches were uneven. Furthermore, although a design effect can be obtained with the flat tape yarn by changing the runner ratio of the insertion yarn and the yarn used for atlas knitting, it has the drawback of insufficient initial elongation in the longitudinal direction and is also flat in shape. Therefore, it has limitations in terms of usage.

(Objective of the Invention) The object of the present invention is to improve such conventional drawbacks and to propose a string-like special yarn that can be produced by a simple method.

(Structure of the Invention) A special yarn composed of a plurality of knitting yarns by knitting into a warp weave using two or more reeds, the total yarn of the special yarn is in the range of 2 to 15. , one of the reeds is underlapped by one or more stitches to cause the knitting yarn to participate in the formation of two or more wales of stitches, and the number is equal to or exceeds the number of underwraps, and The string-like special yarn of the patented invention is characterized in that stitches knitted using a knitting method with light waves in a range less than the total number of wales are arranged in a non-flat shape around the yarn axis of the special yarn. The yarn is a special yarn that exhibits a string-like form obtained by knitting using a warp knitting structure. However, even though a warp knitted structure is used, the stitches are not arranged flat like in normal silk fabric.
That is, as shown in FIG. 1, the stitches are arranged in a non-flat shape around the yarn axis. (FIG. 1 is a perspective view showing the arrangement of stitches of a special yarn according to an embodiment of the present invention.) To obtain such an arrangement of stitches, the total number of wales of stitches constituting the special yarn must be 2 to 2. In particular, in order to obtain a rounded and uniform cross section, the total number of wales is preferably in the range of 3 to 7.If the total number of wales exceeds 15, the special yarn The inner stitches are not arranged in a non-flat shape, and the special yarn of the present invention in a string-like form cannot be obtained.

Next, in the present invention, the knitting yarn forming the special yarn is 2
It is important to be involved in the formation of stitches more than wool wool.

That is, the knitting yarn is underwrapped over one or more stitches by the reed and is involved in the formation of a stitch of two or more wools. As a representative example of the movement of the reed, the Denby edition. There are four types: cord stitch, chain stitch, and atlas stitch, but the special yarn of the present invention is knitted using two or more reeds.
It is organized by combining the Denby edition and the code edition.

In the case of a two-piece reed, double ten-hee set a ((B) 10 ・12/(F) 12-1
0), and a half organization ((B) 10・12/(F) 12・10) which is a combination of J Denby and a cord, and a 1/2 cord set [1 ((B)
23.10/(F)10.23》 etc. are exemplified.

In particular, the combination of two reeds using only the Denbigh structure has a small runner ratio [B:F] (1:1 to 1.04).
Of all the threads that can be used, this method produces the most stable cylindrical special thread.

Furthermore, if you use a 3-piece reed, use lame thread. Weave using colored thread as pattern thread (F) on the front reed ((8) 10.
12/(14)23.10/(F)12.10'', a cylindrical special yarn is obtained as described above and is shown as an example.

In addition, the warp knitted fabric has closed stitches as the stitches obtained by the knitting method.
It is known that there are two types of openings.

In the present invention, the stitches are arranged around the yarn axis in a non-flat shape, but it is preferable to use closed stitches if the stitches are uniform and the yarn form is excellent in the non-flat shape.

FIG. 2 is a knitting diagram showing an example of the special yarn knitting method of the present invention using three reeds.

Figure 2 (a) shows the knitting method using the yarn feeder of the back reed. Of the six yarn feeders, five are used for threading, one is for light wave, and the knitting method for B-01 and 12 is shown. Organized by In this case, one (or more) light waves are required to underlap one stitch by the back reed.

Figure 2 (b) shows the knitting method using the yarn feeder of the middle reed. Of the six yarn feeders, four are threaded as shown in the figure.
The book will be made of light waves and will be knitted using the M-23/10 knitting pattern.

In this case, the middle reed is used to undercut the two stitches.

FIG. 3(C) shows a knitting method using the front reed yarn feeder [1, in which one of the six yarn feeders is used as a yarn guide, and five are used as thread removal.

In the knitting method shown in FIG. 2, a string-like special yarn consisting of all 6-wale stitches is obtained.

FIG. 3 shows an example of another knitting method using two reeds, and FIG. 3(a) shows a knitting method for a back reed, and FIG. 3(b) shows a knitting method for a front reed.

Note that the special yarn of the present invention is not limited to Ma as exemplified above.

Special yarns with such a structure have traditionally been produced using known flat warp knitting machines, and the knitting needles used for zero knitting, which can be produced using tricot knitting machines or raschel knitting machines, can also be produced using known whisker needles and bellow needles. One knitting operation using compound needles can be carried out in the same manner as in the production of ordinary warp knitted fabrics, but the diameter is adjusted by arranging thread removal at appropriately spaced yarn feeders on each reed, and as described above. It is possible to obtain a string-like special thread with a stable shape using this structure. Further, the runner ratio of the main knitting yarn constituting the string-like special yarn is 1. For example, in the knitting method shown in FIG. 3, the runner ratio of the front reed and back reed is F:B=1 (1 to 1.5). A string-like special yarn can be obtained by knitting in the range of F:B-1 (1 to 1.2), more preferably in the range of F:B-1 (1 to 1.2), and using a knitting method in which the thread removal is at least underlap as described above. .

Here, the runner ratio is calculated by the following formula.

Runner ratio (F/B) - Yarn length for knitting 480 courses using the yarn feeder of the front reed/Length of knitting yarn for knitting 480 courses using the yarn feeder of the back reed Furthermore, the knitting yarn constituting the special yarn of the present invention ( That is, as for the type of yarn forming each stitch, all yarns that can be supplied to a knitting machine can be used. That is, in addition to yarns made of natural fibers and artificial fibers, potentially bulky processed yarns can be used, but in order to obtain a design effect, a combination of yarns of different colors is used.
So-called lame thread using gold or silver may also be used.

(Actions and Effects of the Invention) Since the present invention is a special yarn as described above, it has various features. That is, compared to existing braids, braids, etc., ① it is formed from a warp knitted structure, so it has a soft texture and there are no problems such as fraying;

■ Because it is knitted using a warp knitting structure, it has a moderate initial elongation, but after it shows a certain elongation, it will no longer elongate as a knitted fabric, its form will be stable, and it will have good handling properties. be.

■ Since the stitches are arranged in a non-flat shape around the yarn axis and are stable, the bulkiness is also sufficient.

■ When a warp-knitted structure with closed stitches is used, there is no run or fraying of the stitches, and the shape is good.

■ A design effect can be imparted by increasing the number of reeds and inserting lame etc. in one piece or simply. A variety of changes can be obtained by using the Kagaru warp insertion edition as appropriate.

■ Since it is obtained by warp knitting, it can be produced efficiently and as an inexpensive yarn. It has features not found in conventional woolen threads.

(Example 1) Using a two-reed one-helicopter knitting machine (using mustache needles), 500 polyester filament yarns were placed at the yarn feeder of the back reed.
Using de/36 f, thread the threads in an array such as threading 4 threads and pulling out one thread, and add hot water resistant diacedate filament yarn 55 dc/15 f to the front reed.
``Using 1 thread out, 4 threads through, 1 thread out, and thread the back reeds as shown in Figure 3. The yarn feeder of the back reed and the yarn feeder of the front reed were knitted so that the runner ratio of the knitting yarns was B:F=1:1.03.The obtained special yarn had a wale number of It has 5 wells, and the stitches around the yarn axis are non-flat (cylindrical).
It was an excellent special thread for use in hair crafts, etc.

(Example 2) Using a three-reed tricot knitting machine, di-acetate filament yarn 55 de/15 was placed at the yarn feeder of the back reed.
Feed f, thread 5 threads through, and thread one thread out, and insert acetate filament 30 de/8 f and polyester filament 30 f into the yarn feeder of the middle reed.
A blended yarn of 60de/20f using de12f is supplied, two yarns are removed, and the yarn path is arranged like a four yarn path.Furthermore, at the yarn feeder of the front reed, a lame yarn is attached to the polyester film. Vapor-deposited aluminum, 130 cuts/1
00 am is supplied, the thread is guided by arranging one thread through and five threads out, and the back reed is knitted at 10, 12, etc. using the knitting method shown in Fig. 2. Middle reed 23・
10. It was knitted using a knitting method with front reeds of 11 and 12.

The obtained special yarn had a total number of wales of 6, and the stitches were arranged in a non-flat shape around the yarn axis. Because the lame yarn is single-stranded, a special yarn with an excellent design effect was obtained.

(Effects of the Invention) The special yarn of the present invention has a string-like shape with stitches arranged in a non-flat shape around the yarn axis, so it can be used as a handicraft yarn to make flat-knit sweaters and outer garments. It can also be used to tie Japanese clothes, underwear, and footwear.
