Description

The present invention is suitably used when producing garments that are easy to move by producing a sufficient volume for the knitted fabric thickness to provide heat retention and also having abundant flexible stretchability (stretchability). Thick stretch knitted fabric that can be done.

As a circular knitted fabric (cylindrical fabric) knitted using a double circular knitting machine equipped with a cylinder and a dial, a knitted fabric that is light and has a volume is known (see, for example, Patent Document 1 and the like). This known knitted fabric is a single knit using a cylinder-needle (for example, when knitting is performed by providing a plurality of yarn feeders in the course direction with the direction in which the yarn runs (the circumferential direction of the cylinder or dial) as the course direction. , Flat knitting) only course, single knitting course with dial needles, and cylinder-needle side knitted course with dial needle side as tuck to form a knitting structure. It has become.

On the other hand, as another tubular fabric, a knitted fabric raised to enhance heat retention is known (see, for example, Patent Document 2 and the like). Regarding this known brushed knitted fabric, when knitting with a plurality of yarn feeders provided in the course direction, a cylinder-needle single knit course, a dial needle single knit course, and a dial needle side are tacked. A knitted structure is formed by combining a course with a knit on the cylinder side. Then, in the course in which the dial needle side is tack and the cylinder-needle side is knit, the needle loop on the cylinder-needle side is raised.

None of the known knitted fabrics disclosed in Patent Documents 1 and 2 has a course knitted in a double knit (for example, rib knitting) because the stretchability is not emphasized, and the stretchability is high. It wasn't enough. Therefore, even when these knitted fabrics are used, it is not possible to produce a garment that has both a volume feeling of the knitted fabric thickness and stretchability.

The present invention has been made in view of the above circumstances, and is easy to move by providing abundant flexible stretchability (stretchability) while providing heat retention by generating a sufficient volume in the knitted fabric thickness. It is an object of the present invention to provide a thick stretch knitted fabric that can be suitably used when manufacturing garments and the like.
Another object of the present invention is to provide a thick stretch knitted fabric having a knitted structure in which inconveniences such as snacking and expansion of knitted fabric fraying due to run occurrence do not occur even if the stretchability is enriched.

In order to achieve the above object, the present invention has taken the following measures.
That is, the thick stretch knitted fabric according to the present invention includes a tack course knitted including tack and a course covered with the tack loop of the tack course when the direction in which the yarn is run at the time of knitting is set to the course direction. At least two courses of the above are characterized in that they are composed of a knitting structure by plating with a ground yarn and a splicing yarn, respectively.

When the weaving direction intersecting the course direction is set to the wale direction, it is assumed that the two courses arranged on both sides of the wale direction with respect to the tack course are composed of a knitting structure in which the tack is absent. be able to.
Alternatively, a plurality of the tack courses may be continuously arranged in the wale direction.

In the knitting structure by the plating, the splicing yarn is a welded yarn, and the tack course and the course covered with the tack loop of the tack course are fused or fused by the welded yarn. can.
The ground yarn and the splicing yarn constituting the knitting structure of the plating are selected so as to cause a difference in shrinkage ratio between the ground yarn and the splicing yarn, and these ground yarn and the splicing yarn are looped bodies of each other when the shape stabilizes after shrinkage. It is preferable that the yarn is formed with a yarn feed length that allows the yarn to be snuggled up to each other.

Here, the contraction of the ground yarn and the splicing yarn may be based on the elasticity of the yarn material, or may be based on the heating (steam, heated air, press, etc.) applied after knitting.
Further, the contraction of the ground thread and the splicing thread causes a tightening action that constrains the loop of the one having a small shrinkage rate (thread) in shape, especially when the loop of the one having a large shrinkage rate (thread) contracts. In view of this, it is preferable to select the ground yarn and the splicing yarn (as a relationship between the shrinkage rate and the feed length).

The thick stretch knitted fabric according to the present invention is used for producing garments that are easy to move by producing a sufficient volume in the knitted fabric thickness to provide heat retention and also abundant flexible stretchability (stretchability). It can be suitably used for such purposes. In addition, this thick stretch knitted fabric has a knitted structure that is rich in stretchability but does not cause inconveniences such as snacking and expansion of frayed knitted fabric due to run occurrence.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show the first embodiment of the thick stretch knitted fabric (hereinafter referred to as “the knitted fabric of the present invention”) 1 according to the present invention. As is clear from FIGS. 1 and 2, the knitted fabric 1 of the present invention is provided with a tack course 3, and the tack course 3 is a knitted structure plated and knitted by the ground yarn 4 and the splicing yarn 5. ing.

The tack course 3 is pulled up to a loop forming a parallel course and covered at at least one place in the course direction (the direction in which the yarn is run during knitting and is the left-right direction in FIGS. 1 and 2). It has a tack loop 3a. Needless to say, the tack loop 3a is formed by the ground thread 4 and the splicing thread 5.
In this tack course 3, the loop shape of the tack loop by the ground thread 4 and the loop shape of the tack loop by the splicing thread 5 are close to each other (the size of the loop is almost the same), and the beautiful 2 A heavy loop can be obtained.

1 and 2 illustrate the case where the tack course 3 is tacked once and all the loops are tacked. Therefore, the tack loop 3a covers all the loops 8a of the course 8 adjacent to the tack course 3 in the wale direction (the knitting direction intersecting the course direction and the vertical direction in FIGS. 1 and 2). ing.
Then, in the knitted fabric 1 of the present invention, as described above, the course 8 having the loop 8a covered by the tack loop 3a of the tack course 3 also has a knitting structure plated and knitted by the ground yarn 12 and the splicing yarn 13. There is.

In the first embodiment, the course 8 adjacent to the tack course 3 is a double knit course knitted by a double knit such as a rib knit. Further, also in this double knit course 8, the loop shape formed by the ground thread 12 and the loop shape formed by the splicing thread 13 are made to be close to each other when the shape is stabilized after contraction.
As described above, in the knitted fabric 1 of the present invention, the tack loop 3a and the loop 8a covered by the tack loop 3a are both plated and knitted. A quadruple loop 15 composed of a thread 12 and a splicing thread 13] is formed. Therefore, due to the presence of the quadruple loop 15, the knitted fabric 1 of the present invention can generate a sufficient volume for the knitted fabric thickness.

In addition, the knitted fabric 1 of the present invention adopts the following configuration. That is, in the tack course 3, the ground yarn 4 and the auxiliary yarn 5 constituting the knitting structure of the plating are selected so as to cause a difference in shrinkage ratio between them.
What is important here is that even after the thread having the larger contraction rate is contracted, the loop form of the tack loop by the ground thread 4 and the loop form of the tack loop by the splicing thread 5 are close to each other. There is a point.

Therefore, after knitting, the loop with the larger shrinkage rate (yarn) contracts to constrain the loop with the smaller shrinkage rate (yarn) in shape, and the tack loop 3a is tightened so as not to become excessive. A compact and beautiful multiple loop can be obtained.
This not only further enhances the volume-up effect of the knitted fabric thickness, but also has a free-cut property (so-called "cutting" effect) in which the knitted fabric does not loosen or collapse no matter where the knitted fabric is cut. ) Can also be obtained. In addition, since the problem that the thread end pops out at the knitted fabric end can be solved, when the garment is made by the knitted fabric 1 of the present invention, the pain of the knitted fabric caused by repeated putting on and taking off, washing, etc. , It is extremely beneficial in that the effect of suppressing these can be achieved.

In order to select the ground yarn 4 and the splicing yarn 5 so that the shrinkage rates differ from each other, for example, a heat-shrinkable yarn is adopted only for the ground yarn 4, and the feed yarn length is contracted. This can be achieved by setting it to extend for a long time so that it is commensurate with the amount. By doing so, after knitting, the ground yarn 4, which is a heat-shrinkable yarn, contracts more than the attachment yarn 5, and a tightening action that constrains the loop of the attachment yarn 5 in a shape is generated.

For such heat-shrinkable yarn, short fibers such as bulky acrylic can be used.
It is preferable to use a heat-shrinkable yarn having a boiling water shrinkage rate of 8% or more and 45% or less. If the boiling water shrinkage rate is less than 8%, the loop restraining action may be poor and the volume and free cut property of the knitted fabric thickness may be insufficient, and conversely, if the boiling water shrinkage rate exceeds 45%, The knitted fabric volume may become too thick or the basis weight may become excessive due to the strengthened loop restraining action.

However, since it is not always required to satisfy all of the knitted fabric thickness and basis weight, heat shrinkage yarns having a boiling water shrinkage rate of less than 8% (for example, polyester yarns) and boiling water shrinkage rates The use of heat-shrinkable yarns exceeding 45% may be acceptable depending on the content of the knitted fabric.
In order to select the ground yarn 4 and the splicing yarn 5 so that the shrinkage ratios of the ground yarn 4 and the splicing yarn 5 are different from each other, one of the yarns is used as an elastic yarn to give a large stretch at the time of knitting. It can also be achieved by adopting the method.

By the way, the tack course 3 is mainly intended to give a volume to the knitted fabric thickness, while the double knit courses 8 and 17 are mainly intended to enrich the stretchability (stretchability) of the knitted fabric. It can be said that it is the purpose.
Therefore, the main components of the knitting structure, the ground threads 4, 12, 18 (threads that often appear on the front side of the knitted fabric) and the sub-components 5, 13, 19 (threads that often appear on the inside of the knitted fabric) It is better to select the thread type to be used by paying attention to the physical characteristics such as elasticity, strength, thickness, and specific gravity, and the characteristics such as appearance, pattern, texture (feel), and heat retention. ..

However, in the knitted fabric 1 of the present invention, since the tack course 3 and the double knit courses 8 and 17 are plated and knitted, the yarn type to be used is not particularly limited.
For example, as the ground yarns 4, 12, and 18, heat-shrinkable yarns are used in anticipation of a large shrinkage rate, and bare yarns and covering yarns (SCY and DCY) are used in anticipation of elastic action. Can be done.

It is also effective to use bare yarn or covering yarn (SCY or DCY) for the splicing yarns 5, 13 and 19 in anticipation of elastic action. In addition, not from the viewpoint of "elasticity", but from the viewpoint that the knitted fabric after knitting is heat-set (heat-treated), the structure can be expected to be welded or fused. Thread) can also be used. In addition, long fibers such as nylon and polyester can be used alone or in combination with the expectation of acting as inelastic yarns, and cotton yarns and silk yarns can also be used with the expectation of enhancing the texture. Is.

In addition to the case where the splicing threads 5, 13 and 19 are heat-set using the welding thread, the tack course 3 and the course 8 having the loop 8a covered by the tack loop 3a of the tack course 3 are fibers of each other. It is fused or fused by welding yarn at the intersections and parallel portions of the above. This has the advantage that the free-cut property and the effect of preventing the yarn end from popping out at the knitted fabric end can be further enhanced.

Assuming that the tack course 3 is not plated knitted, considering that a volume is generated in the knitted fabric thickness, the knitted fabric is used after being knitted with a double knit such as a conventionally known rib knitting. It was common to adopt a method of increasing the yarn count and the feed length (using a thick yarn and increasing the feeding length).
However, the knitted fabric knitted by this conventional method has problems such as a heavy basis weight (weight) and a decrease in stretchability. If this double knit is plated, there is a risk that the weight of the basis weight will be increased and the stretch will be reduced.

On the other hand, the knitted fabric 1 of the present invention does not have such a problem, so that a knitted fabric that is light and thick and has abundant stretchability can be obtained.
In the first embodiment, the double knit course 8 is followed by the second double knit course 17. In short, the knitted fabric 1 of the present invention of the first embodiment is configured as a so-called three-port repeat in which a total of three courses (8, 11, 17) including the tack course 3 are repeated in the wale direction. It can be said that both sides of the tack course 3 are arranged to form a knitting structure (double knit courses 8 and 17) in which the tack does not exist.

Further, in the first embodiment, the second double knit course 17 is also plated and knitted by the ground yarn 18 and the auxiliary yarn 19. Further, in the second double knit course 17, the loop shape formed by the ground thread 18 and the loop shape formed by the splicing thread 19 are made to be close to each other when the shape is stabilized after contraction.
As a result, in the knitted fabric 1 of the present invention of the first embodiment, the entire knitted fabric has a plated knitted structure. By doing so, we have succeeded in alleviating the difference in volume feeling between courses and preventing it from leading to a sense of discomfort in terms of visual and wearing feeling.

The knitted fabric 1 of the present invention having such a configuration can be knitted by, for example, a double circular knitting machine including a cylinder and a dial (not shown). In this case, while running the yarn in the circumferential direction (course direction) of the cylinder or dial, the yarn is knitted into a tubular shape by feeding yarn from a plurality of yarn feeding ports provided in this course direction.
In the tack course 3 and the double knit courses 8 and 17, it is preferable to raise the loops knitted on the cylinder-needle side to make them fluffy so that the knitted surface on the cylinder-needle side is formed as the skin side surface of the garment.

In order to give the garment a relaxed feeling, when knitting these tack courses 3 and double knit courses 8 and 17, the standard yarn feeding lengths of the ground yarns 4, 12, 18 and the auxiliary yarns 5, 13 and 19. It is advisable to set the yarn feed length to be longer than that at the time of a typical double knit knitting, and to expand the formed loop.
As a result of producing a garment using the knitted fabric 1 of the present invention having the knitted structure of the first embodiment, a sufficient volume is generated in the knitted fabric thickness to provide heat retention, and flexible stretchability (stretchability). We were able to complete the clothes that are easy to move.

By the way, in the knitted fabric 1 of the present invention, the knitting structure is not limited to the three-port repeat of the tack course 3 and the double knit courses 8 and 17. For example, as shown in FIG. 3 as the second embodiment, the second double knit course 17 may be followed by a third double knit course 23 (ground thread 24, splicing thread 25) to form a four-port repeat. ..
In some cases, as shown in FIG. 4 as the third embodiment, the tack course 3 and the double knit course 8 may be a two-port repeat.

In the tack course 3, the tack loop 3a may be formed by a cylinder needle (lower needle) or a dial needle (upper needle). Therefore, for example, as shown in FIG. 5 as the fourth embodiment, the tack course 3 and the double knit course 8 in which the tack loops 3a are alternately formed on the cylinder needle side and the dial needle side may be combined. .. In this case, the tack course 3 can be provided so as to be a plurality of continuous or discontinuous courses in the wale direction.

On the other hand, in the tack knitting adopted in the tack course 3, it is possible to tack twice or three times. For example, as shown in FIG. 6 as the fifth embodiment, in the case of two tacks, the tack loop 3a is covered on the loop 17a of the adjacent course 17 with one course in the wale direction with respect to the tack course 3. It will be. Further, in the case of three-time tack (not shown), the tack loop 3a is put on the loop of the adjacent course after the tack courses 3 to 2 are set.

Even when tacking a plurality of times such as twice in this way, in the knitted fabric 1 of the present invention, a course 17 (see FIG. 6) having a loop 17a covered by the tack loop 3a of the tack course 3 is attached with the ground yarn 18. If the knitting structure is plated with the yarn 19, the tack loop 3a and the loop 17a covered by the tack loop 3a can be used from [ground yarn 4 and splicing yarn 5] and [ground yarn 18 and splicing yarn 19]. The quadruple loop 27 is formed.

Therefore, due to the presence of the quadruple loop 27, the knitted fabric 1 of the present invention can generate a volume sufficient for the knitted fabric thickness.
As is clear from this, the tack loop 3a of the tack course 3 is not necessarily limited to being covered by the "loop 8a of the course 8 adjacent to the tack course 3".

In the fifth embodiment, the tack course 3 is followed by three types of double knit courses 8, 17, and 26 arranged as a four-port repeat. Of these, the double knit course 26 also has a knitting structure in which the ground yarn 28 and the splicing yarn 29 are plated and knitted.
In this case as well, it can be said that both sides of the tack course 3 have a knitting structure (double knit courses 8 and 26) in which the tack does not exist, and the entire knitted fabric has a plated knitting structure.

FIG. 7 shows a sixth embodiment of the knitted fabric 1 of the present invention. In the sixth embodiment, the single knit course 33 knitted by the single knit (flat knit) is arranged on the course adjacent to the tack course 3. This single knit course 33 is also plated with the ground yarn 34 and the splicing yarn 35. Therefore, the tack loop 3a of the tack course 3 is pulled up to the loop 33a of the single knit course 33 and covered.

As a result, the tack loop 3a and the loop 33a covered by the tack loop 3a form a quadruple loop composed of [ground thread 4 and splicing thread 5] and [ground thread 34 and splicing thread 35]. , It is possible to generate a sufficient volume for the knitted fabric thickness.
When the single knit course 33 is adopted, a so-called thread crossing portion 37 appears between the loops adjacent to each other in the course direction. In a conventionally known knitting structure, such a thread crossing portion 37 may be exposed linearly between the ribs on the surface side of the knitted fabric when the knitted fabric is stretched, which may lead to the following problems. there were.

That is, when the thread crossing portion 37 is exposed, the exposed portion is easily caught by contact with other objects such as the nails of the person handling the knitted fabric during washing or use, and snacking (thread from the knitted ground). Was pulled out and frayed), and in extreme cases, it was a factor leading to thread cutting. In addition, once such snacking or thread cutting occurs, a run occurs from that point, which may lead to a tear in the knitted ground that is extremely noticeable in appearance.

However, in the knitted fabric 1 of the present invention, since the single knit course 33 is knitted by a plating knit having a ground thread 34 and a splicing thread 35, the thread crossing portion 37 is in a double reinforced state. become. Not only that, the thread crossing portion 37 is constrained in position by the quadruple loop described above, and the looseness is restricted.
Therefore, it is possible to prevent the thread crossing portion 37 from being snacked or cut due to contact with the nail of a person who handles the knitted fabric 1 of the present invention or another object during washing or use. Further, even if the thread crossover 37 is caught by any chance, the risk of snacking is suppressed as much as possible because the thread crossover 37 is reinforced and is constrained in position. ..

Of course, if a welded yarn is used for the tack course 3 or the single knit course 33 and the knitted fabric after knitting is heat-set, the course 33 has a loop 33a covered by the tack course 3 and the tack loop 3a of the tack course 3. Since the and is fused or fused by the welded yarn, snacking is surely prevented under such a situation.
FIG. 8 shows a seventh embodiment of the knitted fabric 1 of the present invention. This seventh embodiment is further developed based on the sixth embodiment (see FIG. 7), and is also referred to as a tack loop 3a and a welt portion (also referred to as a mistake portion or a floating knitting portion) in the tack course 3. ) A knitting structure in which 3b and 3b are mixed alternately is adopted.

In addition, after repeating the two-port repeat by the tack course 3 and the single knit course 33 six times between the first yarn feeding port and the sixth yarn feeding port, the tack loop 3a and the welt portion 3b of the tack course 3 are arranged. Is shifted by half a pitch in the course direction, and a knitting structure is adopted in which the two-port repeat with the single knit course 33 is repeated 6 times between the 7th yarn feeder and the 12th yarn feeder.

As a matter of course, the tack course 3 is plated knitted with the ground yarn 4 and the splicing yarn 5, and the single knit course 33 is also plated knitted with the ground yarn 34 and the splicing yarn 35.
Therefore, also in the seventh embodiment, the tack loop 3a of the tack course 3 is pulled up to the loop 33a of the adjacent single knit course 33 and covered to form a portion where a quadruple loop is formed.

FIG. 9 shows an eighth embodiment of the knitted fabric 1 of the present invention. In the eighth embodiment, the tack course 3 in which the tack loop 3a is repeated twice and the welt portion 3b is alternately knitted is formed between the 1st yarn feeding port and the 3rd yarn feeding port, and the 5th yarn feeding port. A knitting structure in which a course 40 that repeats between the yarn feeder and the 7th yarn feeder and repeats only the welt portion 3b by the cylinder needle and the welt portion 3b by the dial needle is sandwiched between the 4th yarn feeder and the 8th yarn feeder. There is.

Then, at least the tack course 3 is plated knitted with the ground yarn 4 and the auxiliary yarn 5 (not shown). Therefore, the tack loop 3a of the tack course 3 is pulled up to the loop of the parallel course and covered to form a portion where the quadruple loop is formed.
By the way, the present invention is not limited to the above-described embodiment, and can be appropriately modified depending on the embodiment.

For example, the knitted fabric 1 of the present invention can be knitted by a circular knitting machine equipped with a double cylinder or a flat knitting machine having a two-row needle bed. As is clear from this, the knitted fabric 1 of the present invention according to the present invention is not required to be tubular or to pass through a form knitted as a tubular shape, but as a single flat knitted fabric. It may be organized.
The yarn type used in each course including the tack course 3 is not particularly limited. For example, long fibers are used for the tack course 3 and short fibers are used for the other courses. May be good. Moreover, what is specifically selected as a short fiber or a long fiber is not limited in any way.

In the tack course 3, the pitch in the course direction in which the tack loop 3a is provided is not limited at all. However, it goes without saying that the more the tack loop 3a is, the more the volume is added to the knitted fabric thickness.
In plating knitting, the number of ground yarns and splicing yarns is not limited to one each. In some cases, a plurality of ground threads or a plurality of splicing threads may be used. Therefore, the multiple loop formed by the tack loop 3a of the tack course 3 is not limited to the quadruple loop, and can be implemented in the case of a quintuple loop, a quadruple loop, or the like.

In plating knitting, the arrangement relationship in which the ground yarn and the splicing yarn are close to each other is not particularly important unless it is necessary to specify the front side or the inside of the knitted fabric. Therefore, in the present specification, "plating knitting (plying yarn knitting)" is specifically included in "combined knitting (pulling knitting)".
