Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patterned knitted fabric made by a knitting machine and a knitting method thereof.

[0002]

2. Description of the Related Art Conventionally, when a pattern is created by a knitting machine,
A jacquard structure represented by a combination of knitting needles to be knitted / non-knitted needles for each knitting needle to be put out / not put out on the knitted fabric surface by needle selection control was typical. Its applications are intersia knitting, pile knitting,
Alternatively, a mesh pattern, an eyelet pattern, and the like have been created for a double-sided fabric structure by changing a binding portion (tuck). On the other hand, even in a single jersey knitting machine or a double jersey knitting machine which does not have a needle selection function, a border (horizontal stripe) pattern has been created by combining the arrangement of two-color yarns. It is also known that two colors or two types of yarns are supplied to the same feeder, and a pattern is created on the fabric front side and the fabric back side with a plating structure expressing different colors and yarns. In the case where the original yarn having a color difference or a count difference is used for one yarn itself, such as a design twisted yarn or a slab yarn, a knit having a color difference or a count difference even in ordinary plain knitting or rib knitting. The land is obtained.

[0003]

In the case of the jacquard structure, intershear knitting, pile knitting, double-sided cloth structure, etc., in addition to the actuator device for needle selection control, a number of yarn storages corresponding to the number of feeders are required. A device such as a feeder is required. Therefore, there has been a problem that the equipment cost increases and the control becomes complicated. Above all, the jacquard structure creates a pattern by controlling the color yarn to be exposed / not exposed to the needle loop surface of the knitted fabric, so that the loop length of each stitch is almost constant regardless of whether the color yarn is exposed. However, since the borders of the areas where the colored yarns are exposed stand out clearly, the pattern is too simple and lacks interest.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has a simple structure, from a plain pattern to a peculiar pattern, and is easily formed with a patterned knitted fabric and its knitting. The purpose is to provide a method.

[0005]

In order to achieve the above object, a patterned knitted fabric according to the present invention is provided with a loop obtained by changing a yarn feeding tension applied to a knitting yarn supplied from a yarn guide to a knitting needle. It has a handle consisting of different lengths.

In the knitting method according to the present invention, when yarn is fed from a yarn guide to a knitting needle, a pattern consisting of portions having different loop lengths is formed on a knitted fabric by changing a yarn feeding tension. .

[0007] In the above method, the yarn feeding tension is varied for the knitting yarns in the same course.

Further, when feeding yarn from the yarn guide to the knitting needle, a predetermined yarn feeding tension is applied to knit a predetermined knitted fabric portion, and the predetermined yarn feeding tension is changed to a larger value than the predetermined yarn feeding tension. By knitting a small loop knitted fabric portion having a loop length smaller than that of the knitted fabric portion, a pattern composed of the predetermined knitted fabric portion and the small loop knitted fabric portion is formed.

Further, another knitted fabric with a pattern according to the present invention is applied to at least one kind of a plurality of different kinds of knitting yarns individually supplied from a plurality of yarn guides to corresponding knitting needles. The pattern has a handle composed of portions having different loop lengths obtained by changing the supplied yarn tension.

According to another knitting method according to the present invention, at the time of individually feeding different types of knitting yarns from a plurality of yarn guides to corresponding knitting needles, at least one type of knitting yarn of the plurality of types is used. By changing the yarn feed tension of
This is to form a pattern consisting of portions having different loop lengths on the knitted fabric.

Further, in the knitting method using a plurality of types of knitting yarns, at least one type of knitting yarn other than the knitting yarn for varying the yarn supply tension is supplied by a normal feeding with a constant tension. It is done with yarn.

In a knitting method using a plurality of types of knitting yarns, knitting yarns of different colors or knitting yarns having different dyeing properties are used as the plurality of types of knitting yarns.

In the knitting method using a plurality of types of knitting yarns, knitting yarns having different surface textures are used as the plurality of types of knitting yarns. The knitting yarns having different surface textures are not particularly limited. For example, a combination of a filament (such as nylon) and a spun yarn (such as cotton), a glossy irregular-section filament (such as a triangular section) and a general-purpose filament (such as a circular section) ).

Further, in a knitting method using a plurality of types of knitting yarns, a stretchable yarn is used as at least one type of knitting yarn for changing the yarn feeding tension. The stretchable yarn is not particularly limited. For example, a stretch yarn having a urethane core such as core spun yarn (CSY) or filament twisted yarn (FTY), or a wooly nylon yarn or a wooly ester yarn is used. No.

Further, in the knitting method using a plurality of kinds of knitting yarns, the yarn feeding tension is changed stepwise or steplessly.

In the present invention, the "pattern" is caused by a change in the density of the surface of the knitted fabric, a change in the color tone, gloss or texture of the surface of the knitted fabric, or a geometric change in a continuous loop on the surface of the knitted fabric. The above-described change in density varies due to a change in loop length (loop size) depending on a portion on the surface of the same knitted fabric. The change in color tone, gloss, or texture is caused by changing the loop length for each yarn type using a plurality of types of knitting yarns, thereby changing the ratio of each yarn appearing on the surface of the knitted fabric. The geometric change of the continuous loops occurs when the loops continuous in the course direction are arranged not in a straight line but in a wave shape, for example, due to a change in the loop length. Further, a change in the amount of transmitted light due to density changes also has the effect of the pattern.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a knitting machine for knitting a patterned knitted fabric according to one embodiment of the present invention, FIG. 2 is a side view of a tension varying device provided in the knitting machine, and FIG. It is a front view. In each of the drawings, the knitting machine 1 used in this embodiment is configured so that, for example, the knitting yarn Y is once pulled up from the yarn cone 6 to the upper part of the knitting machine, then passed through the yarn guide 5, and guided to the knitting needle 3 via the feeder 4. Have been. Here, as the knitting machine 1, a large number of knitting needles 3, 3, 3,...
A generally known circular knitting machine provided with a plurality of sets of a thread cone 6, a thread guide 5, and a feeder 4 corresponding to the individual knitting needles 3 so as to individually feed the knitting yarns Y. .

In the knitting machine 1, the yarn feeding tension of the knitting yarn Y (one knitting yarn Ya in the knitting machine 1 of FIG. 4 described later) supplied from the yarn guide 5 to the knitting needle 3 fluctuates during knitting of the knitted fabric. A tension varying device 30 is provided. The tension changing device 30 slides on the knitting yarn Y (Ya in FIG. 4) to be fed and slides the knitting yarn Y (Y
a) tension applying mechanism 7 for applying tension to a), and tension applying mechanism 7
, And a control device 12 and a driver 13 for controlling the drive of the motor 10.

The control device 12 has a sequencer 15 for calculating the control operation of the tension applying mechanism 7 and outputting a command signal, and a memory 16 for reading and writing setting data such as a counter n and a counter m described later. I have. On the data input side of the sequencer 15, a position detection sensor 11 for detecting a predetermined knitting start position and an external input device 14 represented by a keyboard or the like are connected. The data output side of the sequencer 15 is connected to the driver 13.
The driver 13 supplies a drive current to the motor 10 to
The zero drive shaft 25 is rotated forward and backward as indicated by an arrow U (see FIG. 3).

The tension applying mechanism 7 is provided on a traveling path of the knitting yarn Y (Ya in FIG. 4) from the yarn guide 5 to the feeder 4. The tension applying mechanism 7 includes four fixed comb rods 9, 9, 9, 9 erected on the base 17 at appropriate intervals via a fixing member 26, and fixed comb rods 9, 9. , 9 and 9 swinging into each other 4
And two movable comb-shaped rods 8, 8, 8, 8.
The roots of the movable comb-shaped rods 8, 8, 8, 8 are fixedly mounted on a swing table 19. The swing table 19 has pivot shafts 20, 2 at both ends of a foot table 18 fixed on the base 17.
, The movable comb rods 8, 8, 8, 8 are fixed to the fixed comb rods 9, 9, 8,.
It is configured to be close to and apart from W (9, 9) (W direction in the figure). The motor 10 is mounted on the lower surface of the base 17, and it is preferable to use, for example, a servo motor or a stepping motor for performing high-accuracy tension control. However, a solenoid actuator or the like can be used instead.

The swing table 19 is provided with a connecting rod 21 extending below the base 17. On the other hand, a lever 24 is fixed to a drive shaft 25 of the motor 10, and a shaft 23 protrudes from the front surface of the lever 24. The shaft 23 is movably inserted into a vertically long shaft insertion hole 22 drilled below the connecting rod 21. Thus, the movable comb rods 8, 8, 8, 8 and the drive shaft 25 are drivingly connected.

On the other hand, two different types of knitting yarns Ya and Y
When using b, the knitting machine 1 shown in FIG. 4 is used. In this knitting machine 1, at least two feeders 4 and 4 are used, one for each knitting yarn. Knitting yarn Ya
Is supplied to the knitting needle 3 via the cone 6, the yarn guide 5, the tension applying mechanism 7, and the feeder 4, as in the case of the knitting yarn Y described above.
The knitting yarn Yb is supplied to another knitting needle 3 via a cone 6, a yarn guide 5, and a feeder 4, which is separate from the knitting yarn Ya.

Next, a method of knitting a patterned knitted fabric by the knitting machine 1 having the above-described configuration will be described mainly with reference to FIGS.
Here, one check pattern knitted fabric E (two in FIG. 4)
An example of knitting with the knitting yarn Y (Ya and Yb in FIG. 4) is shown. In the figure, n is a knitting yarn Y for each pattern (Ya or Y in FIG. 4).
The number of courses in b) is shown, and here is 1 to 35. m indicates the number of small loop knitted fabric portions H (or predetermined knitted fabric portions L) in one course. Here, m = 1 to 10, and one round of the cylinder 2 is equally divided into ten.
In other words, 10 sets of the small loop knitted fabric portion H and the predetermined knitted fabric portion L are repeatedly knitted in the course direction (the direction of arrow C, that is, the circumferential direction of the cylinder 2). In addition, one course in the knitting machine 1 in FIG. 4 is an amount in which the two knitting yarns Ya and Yb are knitted around the cylinder 2 together.

First, when the position detecting sensor 11 detects and outputs the knitting needle 3 at the knitting start position, the sequencer 15 of the control device 12 receives a signal PS indicating the detection of the knitting start position (step S1). Therefore, the sequencer 15 rewrites the counter n of the memory 16 by incrementing it by one from 1 (step S2). At this point, the counter n is 35
(N in step S3), the processing procedure proceeds to step S4. Since the pattern mode to be knitted at the beginning of the process is set to, for example, pattern A (step S4).
A), the signal A is output to the driver 13 in step S5. As a result, the driver 13 drives the motor 10 to cause the movable comb-shaped rod 8 of the tension applying mechanism 7 to enter the fixed-side comb-shaped rod 9. The signal A and a signal B described later are not continuous but instantaneous signals.

When the movable comb rod 8 swings and enters between the fixed comb rods 9 by the output of the signal A, the knitting yarn Y for the movable comb rod 8 and the fixed comb rod 9 is moved.
(Ya in FIG. 4) (the lower knitting yarn Y1 in FIG. 7 (Ya1 in the small loop knitted fabric portion Ha in FIG. 13)) has a high frictional force, and the knitting yarn Y (Ya) supplied to the knitting needle 3 Tension increases. Then, shortly after the output of the signal A, a stitch having a small loop length r (see FIG. 7) is knitted, and a small loop knitted fabric portion H having a dense structure is formed. The knitting start portion and knitting end portion of the small loop knitted fabric portion H are gradation portions g in which the density of the stitches and the shading of the color gradually change.
(See FIG. 8). The movable comb rod 8 once enters the fixed comb rod 9 by the signal A, and then is automatically returned in the direction opposite to the entering direction. As a result, the yarn feeding tension of the knitting yarn Y decreases, the stitch returns to the normal loop length R (see FIG. 7), and a predetermined knitted fabric portion L having a coarse structure is formed.

The sequencer 15 sets the counter m to 1
Is rewritten by incrementing by one (step S
6). At this point, since the counter m has not reached 10 (N in step S7), the processing procedure proceeds to step S8, and waits for a lapse of time T until the next signal output. When the time T has elapsed (Y in step S8), the processing procedure returns to step S5, and the processing in steps S5 to S7 is repeated for the remaining nine times. When the counter m reaches 10 as described above for one course (Y in step S7), the counter m is reset to 1 (step S7).
9), the procedure returns to step S1. The processing of steps S1 to S9 is repeated until the counter n reaches 35. Thereby, the knitting yarns Y1 to Yn for 35 courses
(N = 1 to 35), the knitted fabric E was knitted, and starting from the small loop knitted fabric portion H, the small loop knitted fabric portion H and the predetermined knitted fabric portion L were alternately knitted in the course direction (arrow C direction). A pattern A (see FIG. 6) is formed. In addition, two kinds of knitting yarns Ya,
In the case of knitting using Yb, as shown in FIG. 13, the knitting yarn Y for 70 courses (Ya and Yb are each 35 courses).
a1 to Ybn (n = 1 to 35)), the knitted fabric E9 is knitted, starting from the predetermined knitted fabric portion L2, and starting from the predetermined knitted fabric portion L.
2. Small loop knitted fabric portion Ha is in the course direction (arrow C direction)
A pattern formed alternately is formed.

As described above, when the counter n reaches 35 (Y in step S3), the pattern mode to be knitted is the pattern A
To the pattern B (see FIG. 6) (step S1).
5), the counter n is reset to 1 (step S1)
6). Since the pattern mode to be knitted is the pattern B (B in step S4), the process waits until the time T / 2 (half of the time T between the signals A to A described above) until the signal output elapses (step S10). N). When the time T / 2 has elapsed (Y in step S10), a signal B is output to the driver 13 in step S11. Then, as in the case of signal A,
The driver 13 drives the motor 10 and the tension applying mechanism 7
Of the movable side comb rod 8 is inserted into the fixed side comb rod 9. As a result, the frictional force of the knitting yarn Y (Ya in FIG. 4) is increased, and the small loop knitted fabric portion H having the small loop length r is formed.
Is formed.

Then, the sequencer 15 sets the counter m to 1
Is incremented by one and rewritten (step S1
2). At this point, since the counter m has not reached 10 (N in step S13), the processing procedure proceeds to step S14, and waits for the lapse of time T until the next signal output. When the time T has elapsed (Y in step S14), the processing procedure returns to step S11, and the processing in steps S11 to S13 is repeated for the remaining nine times. When the counter m reaches 10 in this way (Y in step S13), the counter m is reset to 1 (step S9), and the processing procedure returns to step S1. Steps S1 to S4, S
Steps S10 to S14 and S9 are repeated until the counter n reaches 35. Thereby, the knitting yarn Y1 for 35 courses
13 to knitting yarns Ya1 to Yb in FIG.
n) A knitted fabric according to (n = 1 to 35) is knitted, and starting from a predetermined knitted fabric portion L, a predetermined knitted fabric portion L and a small loop knitted fabric portion H are alternately knitted in a course direction (arrow C direction). Pattern B
Is formed. In the pattern B, two types of knitting yarns Ya and Y
b, knitting yarn Ya1 as shown in FIG.
The knitted fabric E9 is formed by .about.Ybn (n = 1 to 35).

When the counter n reaches 35 (step S)
3) The pattern mode to be knitted is switched from the pattern B to the pattern A again (step S15), and the counter n is reset to 1 (step S16). Subsequently, the entire processing procedure described above is repeated. The small loop knitted fabric portion H in the pattern B described above is disposed adjacent to the predetermined knitted fabric portion L in the pattern A in a direction perpendicular to the course direction (the direction of arrow C). In this way, the knitted fabric E of the check pattern including the pattern A and the pattern B is obtained.

As described above, in the patterned knitted fabric E according to this embodiment, the tensioned portion (H) and the relaxed portion (L) in which the loop lengths of the knitting yarns are different are intentionally arranged, and a combination thereof is provided. Has a pattern due to density change. The knitting method of the knitted fabric E is based on a simple control configuration in which a knitting machine for knitting a plain knitted fabric having no jacquard function and a normal yarn are used to apply / do not apply tension to the supplied yarn. In such a knitting method, instead of a color pattern,
If a knitted fabric with an uneven surface or a different texture is created as a result of the difference in loop length, knitting with at least one thread is sufficient.
Further, in the case of forming an uneven color pattern by using colored yarns, knitting with at least two yarns including colored yarns is sufficient. In these cases,
The cam position for performing ordinary flat knitting can be maintained, and the cam adjustment for each thread is unnecessary. Further, a needle selecting device for knitting each color yarn at a knitted fabric portion where a color pattern is desired is not required.

In addition, the boundary between the small loop knitted fabric portion H and the predetermined knitted fabric portion L in the knitted fabric E is a faint gradation portion g, and exhibits a completely new pattern.
In particular, when a color pattern is expressed by a combination of exposing a large amount of color yarn on the surface of the knitted fabric / not exposing the color yarn due to a difference in loop length, the gradation at the boundary between the multi-exposure portion of the color yarn and the low-exposure portion of the color yarn is remarkably apparent. Next to beautiful. Further, in this embodiment, the stitch portions of the large and small loops are present at a constant pitch within one course, and are formed continuously for several tens of courses. As a result, the tensioned portion and the relaxed portion are repeatedly arranged along the course direction, so that a quaint knitted fabric having a somewhat uneven surface can be obtained despite the plain single jersey structure.

In the knitting method of this embodiment, the counter n and the counter m used in the control program, the pattern mode switching, the output timing of the signals A and B, and the like are changed, and a part of the program is appropriately changed. By
Knitted fabrics of various patterns can be knitted. For example, FIG.
As shown in the figure, a knitted fabric E2 having a stripe pattern (FIG. (A)), a knitted fabric E3 having a void check pattern (FIG. (B)),
Knitted fabric E4 with rhombic check pattern (FIG. (C)), knitted fabric with spiral pattern E5 (FIG. (D)), knitted fabric with satin-like random pattern E6 (FIG. (E)), random border pattern E7 Knitted fabric (figure (f)), knitted fabric E8 with border pattern (g (g))
Is a knitting example. Hatched portions and bold lines in the patterned knitted fabrics E2 to E8 shown in FIGS. 9A to 9G represent small loop knitted fabric portions. It should be noted that the knitted fabric E6 having a satin-like random pattern as shown in FIG. 9E lacks interest as a pattern as it is. In particular, when a single circular knitting machine is used to knit with only one kind of knitting yarn, it may be difficult to confirm the pattern. In such a case, if a plurality of types of knitting yarns are used, a pattern having a tasteful and clear contour can be obtained.

Hereinafter, several embodiments of the present invention will be described. [Example 1] Using a single jersey knitting machine (20 gauge, 1,500 needles, 24 inches) manufactured by Higuchi Co., under an aggressive yarn feeding using an air tape, undyed cotton yarn (first yarn The knitting yarn supplied to the feeder is marked with. The same applies to the following. An undyed cotton yarn of the same type as the second feeder is used (for the knitting yarn supplied to the second feeder). And the same applies hereinafter). Therefore, the yarn feeding tension is applied to the knitting yarn by the action of the tension applying mechanism 7 driven by the motor 10 /
By performing the two-stage control without adding, a check pattern of a different density structure was created. In this case, as in the case of the knitted fabric E1 shown in FIG. 10, the small loop knitted fabric portions H1 are arranged in a stepping stone shape between the predetermined knitted fabric portions L1.

The following Examples 2 to 6 and Example 11 show examples in which different types of knitting yarns are supplied to a plurality of feeders by using the same knitting machine as shown in FIG. I have. Further, Embodiments 7 to 10 and Embodiment 1
No. 2 includes an example in which different types of knitting yarns are supplied to a plurality of feeders, as well as an example in which the same type of knitting yarn is supplied (Example 1).

Example 2 Knitting was performed in the same manner as in Example 1 except that the undyed cotton yarn and the undyed cotton yarn in Example 1 were replaced with an undyed yarn and a dyed cotton yarn. Thereby, the knitted fabric E1 having the check color pattern of the different density structure
was gotten. In this case, the small loop knitted fabric portion H1 appeared darker than the predetermined knitted fabric portion L1 because the undyed cotton yarn was squeezed into the small loop and the dyed cotton yarn was raised on the knitted fabric surface. Further, gradation portions g, g at the boundary between the small loop knitted fabric portion H1 and the predetermined knitted fabric portion L1 also appeared clearly and exhibited a unique pattern.

FIG. 11 shows an enlarged photograph of the predetermined knitted fabric portion L1 (FIG. 13A) and the small loop knitted fabric portion H1 (FIG. 13B). Looking at these photos,
The area occupied by the knitting yarn Ya (the above-described yarn) is smaller in the small loop knitted fabric portion H1 than in the predetermined knitted fabric portion L1, and the colored knitting yarn Yb (the above-described yarn) appears darker. You can see that.

Example 3 Knitting was performed in the same manner as in Example 1 except that undyed ester yarn and undyed cotton yarn were used instead of the undyed cotton yarn and undyed cotton yarn in Example 1. When the knitted fabric after knitting was dyed with a reactive dye, a knitted fabric E1 having a check pattern of a different density structure, in which only the cotton yarn was dyed and the ester yarn remained undyed, was obtained. in this way,
Even in the case of post-dyeing utilizing the difference in the dyeing properties of the yarn used, there are effects such as the color density and the specificity of the gradation parts g, g, as in the case of the first dyeing Example 2. When the undyed knitted fabric knitted as described above is post-dyed with a disperse dye, a knitted fabric E1 is obtained in which only the ester yarn is dyed and the cotton yarn remains undyed.

Example 4 Knitting was carried out in the same manner as in Example 1 except that a filament undyed yarn and a dyed cotton yarn were used instead of the undyed cotton yarn and the undyed cotton yarn in Example 1. As a result, a knitted fabric having a check color pattern of a different density structure was obtained. In this case, the undyed filament yarn having an irregular cross section has a glossy yarn surface and a different texture than the dyed cotton yarn, so the obtained knitted fabric has a pattern due to the difference in texture even when the yarn has the same color. Present.

Example 5 Knitting was carried out in the same manner as in Example 1 except that undyed cotton yarn and dyed cotton yarn were used instead of undyed cotton yarn and undyed cotton yarn in Example 1. As a result, a knitted fabric having a check color pattern of a different density structure was obtained. In this case, the knitted fabric E9 having a diamond-shaped check pattern as shown in FIG. 12 was obtained by sequentially delaying or sequentially advancing the tension applying time point in each course in the wale direction.

Further, by using an elastic stretch yarn as the knitting yarn Ya on the side to which tension is applied, the knitted fabric E9 has a small loop length ra by forcible tension application as shown in FIG. The formed small loop knitted fabric portion Ha and the predetermined knitted fabric portion L2 formed with a normal-sized loop length R by a normal yarn supply that does not cause a tension variation include a course direction (arrow C direction) and a wale direction (arrow arrow). D direction) to form a check pattern. In this case, the loop length ra of the knitting yarn Ya in the small loop knitted fabric portion Ha is significantly smaller than the loop length R in the predetermined knitted fabric portion L2. Incidentally, if the loop length R of the predetermined knitted fabric portion is made the same size, the knitting yarn Y
The loop length ra of a is smaller than the loop length r of the small loop knitted fabric portion H shown in FIG. As a result, the wave of the rhombus contour became larger, and the contrast of the pattern became remarkable.

FIG. 14 is an enlarged photograph of a predetermined knitted fabric portion L2 (FIG. 14A) and a small loop knitted fabric portion Ha (FIG. 14B) of the knitted fabric E9. When observing these photographs, the small loop knitted fabric portion Ha has a smaller apparent area occupied by the knitting yarn Ya than the predetermined knitted fabric portion L2,
It can be seen that the colored knitting yarn Yb appears dark. The color density difference between the predetermined knitted fabric portion L2 and the small loop knitted fabric portion Ha is better than the color density difference between the predetermined knitted fabric portion L1 and the small loop knitted fabric portion H1 shown in FIGS. 11 (a) and 11 (b). It can be seen that the difference is larger.

Example 6 Knitting was carried out in the same manner as in Example 1 except that the undyed cotton yarn and the undyed cotton yarn in Example 1 were replaced with a filament stretch yarn undyed yarn and a filament yarn undyed yarn. . As a result, a knitted fabric having a check pattern of a different density structure was obtained. Also in this case, the effect of making the contrast remarkable was obtained as in Example 5.

[Embodiment 7] With the same combination of knitting yarns as in Embodiments 1 to 6, the signal A or B to the driver 13 is output randomly by the controller 12 to
A knitted fabric E6 having a random pattern as shown in (e) was obtained.

[Embodiment 8] By outputting the signal A or B at the same position in the direction of arrow C for each course with the same combination of knitting yarns as in Embodiments 1 to 6, it is shown in FIG. A knitted fabric E2 having such a stripe (vertical stripe) pattern was obtained.

Example 9 A knitted fabric with a handle was obtained by knitting under the same conditions as in Examples 1 to 8, except that the positive yarn feeding in Examples 1 to 8 was changed to the negative yarn feeding.

[Embodiment 10] With respect to the knitting yarns in Embodiments 1 to 9, together with the knitting yarn, the tension is varied by the tension varying device 30. In this case, the knitting yarn of Example 1 is used.
9 to 9, the tension is not applied by the tension varying device 30 in the predetermined knitted fabric portion L1 (see FIG. 10), and the tension is applied in the small loop knitted fabric portion H1 (see FIG. 10). On the other hand, in contrast to the knitting yarn, the knitting yarn is applied with tension at the portion L1,
At the portion of H1, tension is not applied. The knitting yarn with the knitting yarn at the portion L1 in Examples 1 to 9 appeared at a substantially equal ratio on the surface of the knitted fabric.
By performing control such as 0, the loop of the knitting yarn at the portion L1 is reduced, and the proportion of the knitting yarn appearing on the surface of the knitted fabric is increased. Therefore, the change in the ratio of the knitting yarn occupying the surface of the knitted fabric between the portion of H1 and the portion of L1 is shown in Example 1.
~ 9, and as a result, Examples 1-9
A knitted fabric with more remarkable contrast was obtained.

Example 11 Using the knitting machine described in Example 1, red dyed cotton yarn was used for the first feeder, blue dyed cotton yarn was used for the second feeder, and yellow dyed cotton yarn was used for the third feeder. We assume dough knitting. The tension variation devices are individually provided for all of the knitting yarns, and each tension variation device can be controlled independently. When tension is applied only to the knitting yarn, the loop length of the knitting yarn decreases, and the ratio of the loop to the knitted fabric surface decreases. Therefore, a green color which is an intermediate color between the two appears on the surface of the knitted fabric. Similarly,
Also, when tension is applied to only one line, the remaining two intermediate colors are expressed. Furthermore, two out of three knitting yarns
When tension is applied to the knitting yarn of the book, the remaining one color is remarkably expressed and expressed. As described above, the yarn feeding tension of two or more (three in this case) knitting yarns is individually varied, and the individual timings at which the tensions are applied are also controlled by, for example, a computer, so that various kinds of yarns can be provided. You can express various colored patterns.

[Example 12] In Examples 1 to 11,
Instead of two-step control of applying / not applying tension, a stepping motor or the like is used
0 was controlled in multiple steps or steplessly. by this,
In Examples 1 to 10, gradation could be given to the shading of the pattern. In Example 11, a knitted fabric having a pattern with gradation in color tone was obtained.

FIG. 15 shows a photograph of the knitted fabric E10 obtained in Example 12 described above. The knitted fabric E10 has a rhombic pattern similar to the small loop knitted fabric portion Ha of FIG. 12, but the entire diamond shaped pattern is a small loop knitted fabric portion H13 formed sequentially in the wale direction (arrow D direction). , H12 and H11. These are formed by applying a large tension to the knitting yarn Ya in the order of the small loop knitted fabric portion H11, the small loop knitted fabric portion H12, and the small loop knitted fabric portion H13. That is, the small loop knitted fabric portion H11 and the small loop knitted fabric portion H
12, the small loop knitted fabric portion H13 is arranged in a gray scale in that order in color. The small loop knitted fabric portion H13 is lighter than the small loop knitted fabric portion H12, but slightly darker than the predetermined knitted fabric portion L2.

In the embodiments and examples described above, the small loop knitted fabric portion is formed with the yarn feeding tension larger than the yarn feeding tension used for knitting the predetermined knitted fabric portion. The method for knitting a patterned knitted fabric of the present invention is not limited thereto, and includes, for example, a case where a large loop knitted fabric portion is formed with a yarn feeding tension smaller than the yarn feeding tension used for knitting a predetermined knitted fabric portion. Is done. In addition, the knitted fabrics E, E1,
E2 to E7, E9 and E10 have a small loop knitted fabric portion and a predetermined knitted fabric portion in the same course, but the method of the present invention is not limited thereto. For example, several tens of courses may be formed by setting the entire course to a small loop knitted fabric portion H, and then several tens of courses may be formed by setting the entire course to a predetermined knitted fabric portion L. This makes it possible to obtain a knitted fabric E8 having a border pattern as shown in FIG. 9 (g).

It is also possible to knit a patterned knitted fabric using a larger number of yarn types (for example, four or more types) than the yarn types shown in the above-described embodiments and examples. By individually controlling the tension of the knitting yarn by the tension varying device, variations in the pattern can be improved. It is also possible to knit a knitting yarn that performs tension control and a knitting yarn that does not perform tension control in a mixed manner.

The tension applying mechanism of the present invention is not limited to the comb-shaped mechanism described above. For example, a mechanism for adjusting the yarn feeding tension by passing a knitting yarn between two cymbal-shaped disks may be employed. The knitting machine to which the present invention is applied is not limited to the circular knitting machine described above, but may be, for example, a flat knitting machine. And
The present invention can be applied to not only the flat knitting described above but also, for example, double-sided knitting, pile knitting, rib knitting, interlock knitting, and the like.

As described in detail above, the patterned knitted fabric according to the present invention provides a new pattern having a feeling of coarse / dense or unevenness even when one kind of yarn is used due to density change. You. Then, the portion where the density changes gradually changes in a gradation form to obtain a unique pattern.

Further, according to the knitting method of the present invention, the size of the loop length is controlled by a simple structure in which the yarn feeding tension is intentionally fluctuated, and the pattern pattern of the density change composed of the portions having different loop lengths. Can be applied to the knitted fabric.
That is, for example, a knitting machine having no needle selection function such as a jacquard can form stitches having different loop lengths by controlling the yarn feeding tension during knitting, and can create a pattern by density change.

When the yarn feeding tension is varied for knitting yarns in the same course, a knitted fabric having a stripe, various checks, a spiral, a random pattern, and the like can be obtained.

Furthermore, a predetermined knitted fabric portion is knitted by applying a predetermined yarn feeding tension, and a small loop knitted fabric having a smaller loop length than the predetermined knitted fabric portion is changed to a yarn feeding tension larger than the predetermined yarn feeding tension. When the portions are knitted, a pattern composed of a predetermined knitted fabric portion having a coarse stitch and a small loop knitted fabric portion having a dense stitch can be formed.

When a plurality of types of knitting yarns are used, and the yarn feeding tension of at least one of the yarns is changed, the part where the yarn feeding tension of the knitting yarn is changed and the part where the yarn feeding tension is not changed are less dense and dense. It is a matter of course that a pattern due to the difference is formed. In a portion where the tension is varied, a knitting yarn which has not been subjected to the tension variation emerges on the surface of the knitted fabric and has an effect of remarkably attracting the pattern.

When a plurality of types of knitting yarns other than the knitting yarn for changing the yarn supply tension are normally fed with a constant tension, a knitting yarn for controlling the tension and a knitting yarn normally fed with a constant tension are used. Can be knitted together. Note that tension control may be performed on all the yarns. In that case, the change in the ratio of each of the knitting yarns on the surface of the knitted fabric can be increased, and as a result, the contrast of the pattern becomes remarkable.

When knitting yarns of different colors are used as a plurality of types of knitting yarns, a knitted fabric having a color pattern can be obtained by combining the colors of the knitting yarns. For example, the use of a plurality of different colored yarns provides a new color pattern in which certain colored yarns can be seen or hidden from the density difference on the surface of the knitted fabric. On the other hand, when knitting yarns having different dyeing properties are used, a desired color and pattern can be obtained by dyeing the knitted fabric in a process after knitting. When the yarns having different colors are used as described above, the effect that the gradation of the portion where the density changes becomes more beautiful is also exhibited.

When knitting yarns having different surface textures are used as a plurality of types of knitting yarns, a knitted fabric having a pattern whose texture, such as gloss and feel, has changed can be obtained.

When a stretchable yarn, for example, a stretch yarn, is used as a knitting yarn controlled by varying the tension among a plurality of different types of knitting yarns, compared with a normal knitting yarn having a small stretchability. This has the effect of increasing the change in loop length and making the contrast of the pattern remarkable.

Further, by performing a multi-step or stepless control using a stepping motor or the like instead of the two-step tension control, it is possible to impart gradation to the density and color tone of the pattern. For example, when a knitting yarn of two colors such as white and chromatic color is used, the gradation of the pattern can be given. Further, when three or more kinds of knitting yarns having different color tones are used, gradation can be given to shading and color tones, and a knitted fabric with a pattern in various variations can be knitted.
