Description

  The present invention relates to a stretch warp knitted fabric. Specifically, the present invention relates to an elastic warp knitted fabric that is partially provided with an elongation control region in which the elongation of the knitted fabric is controlled and is suitable for body shape correction of the wearer.

Conventionally, for the purpose of imparting a body shape correction function or the like, it has been performed to partially form an extension control region on a stretchable warp knitted fabric. For example, a stretchable main body portion and a belt-like first tightening portion and second tightening portion that are arranged in a pair of left and right of the main body portion and have a tightening force stronger than the tightening force of the main body portion are specified. There is known a bottom garment that can provide a shape-up effect mainly around the stomach (see Patent Document 1).
In general, such a partial elongation control region is formed by a patch. However, in this method, a step is generated in the stitched portion of the patch, or different materials such as a cloth and a patch are used. There was a problem that a sense of incongruity could occur due to the stitching.

In view of this, a method has been proposed in which a partial stretch control region is formed by changing the knitted structure, instead of using a patch.
For example, as a fabric knitting structure, a technique is known in which a portion where a tightening force is desired to be strengthened is a satin-like structure and another portion is a mesh-like structure, and a tightening portion having a desired shape is obtained without using a patch (patent) Reference 2).
However, with the technique described in Patent Document 2, it is difficult to make a large difference in tightening force, and the degree of freedom of the knitting structure of the fabric is extremely low.
Therefore, as a further improvement technique, the yarn for increasing the tightening force is continuously knitted into the ground structure over the strong tightening portion and the weak tightening portion, and as the knitting structure of the yarn for increasing the tightening force, A technique is known in which a ratio of a looping tissue and an insertion tissue is appropriately determined to provide a difference in tightening force (see Patent Document 3).
JP 2006-328602 A Japanese Patent No. 3461316 JP 2007-113125 A

However, the technique described in Patent Document 3 has a problem in that the sense of unity of the product is impaired because a yarn for increasing the tightening force must be separately prepared in addition to the knitted structure of the fabric.
In the above prior art, the tightening force can be partially increased, but the extension in the vertical and horizontal directions cannot be sufficiently controlled.
Therefore, the problem to be solved by the present invention is that it is not necessary to use a patch cloth or to sew another fabric, and it is not necessary to separately prepare a special thread other than the fabric knitting structure, and the fabric To provide a stretch warp knitted fabric partially including an elongation control region in which the elongation in the vertical and horizontal directions is sufficiently controlled by the knitting structure of the fabric without greatly reducing the degree of freedom of the knitting structure of the fabric. is there.

  The present inventor has intensively studied to solve the above problems. As a result of various investigations on the knitting structure of the fabric, the first inelastic yarn is used for each course and / or every two courses using the first inelastic yarn and the second inelastic yarn. The second inelastic yarn is swung across the entire course of the extension control region and / or inserted into the stitch without exceeding the range of two stitches with a swing width of 4 to 7 stitches; Thus, it has been found that a region in which the stretching in the vertical and horizontal directions is sufficiently controlled can be formed, and an elastic warp knitted fabric partially provided with this stretch control region has a stretch control region formed by a knitted structure. Therefore, it is not necessary to use a special yarn other than the knitted structure, and the knitted structure can be freely changed within a range that satisfies the above-described configuration. Nor Heading the door, make sure it was completed the present invention.

That is, elastic warp knitted fabric according to the present invention (except a strip-shaped region curved.) Shin length control region a stretchable knitted fabric Ru comprising partially the extension control region, first The non-elastic yarn is alternately swung left and right with a swing width of 4 to 7 stitches every course and / or every 2 courses, and the second inelastic yarn does not exceed the range of 2 stitches over the entire course of the extension control region. A stitch is formed and / or inserted.

  According to the present invention, there is no need to apply a patch, a separate fabric, the use of a special thread other than the knitted fabric of the fabric, and the like, without excessively reducing the degree of freedom of the knitted fabric that can be applied. It is possible to provide an elastic warp knitted fabric partially provided with an elongation control region in which elongation in the vertical and horizontal directions is sufficiently controlled by the knitted structure.

Hereinafter, the stretch warp knitted fabric according to the present invention will be described in detail. However, the scope of the present invention is not limited to these descriptions, and other than the following examples, the scope of the present invention is not limited. Changes can be made.
[Elastic warp knitted fabric]
As the stretch warp knitted fabric according to the present invention, for example, a combination of the structures A to C, O, and P as shown in FIGS.
The tissues A and B are formed by the first inelastic thread 10 and the second inelastic thread 20, respectively, and the extension control region Y is partially formed by changing the structure. A region other than the expansion control region Y is an expansion / contraction region X. However, a course for smoothly connecting the two areas may be provided between the expansion / contraction area X and the extension control area Y (in the example shown in FIGS. 1 and 2, one course is used for connecting both areas). . Although not particularly limited, for example, the stretchable region X can be 6 to 2800 courses, and the extension control region Y can be 6 to 2200 courses.

  Here, in the extension control region, the first inelastic yarn is alternately swung left and right with a swing width of 4 to 7 needles every course and / or every two courses, and the second inelastic yarn is placed in the extension control region. The mechanism of elongation control by forming and / or inserting a stitch without exceeding the range of two needles over the entire course is as follows. That is, the first inelastic yarn greatly swung in the horizontal direction every course and / or every two courses, and the second inelastic thread forming and / or inserting a stitch almost linearly in the vertical direction , In the transverse direction, the larger the swing width of the first inelastic yarn, the more second inelastic yarn is held between the swing widths. In the warp direction, since the number of first inelastic yarns crossing per second inelastic yarn is large, the knitted fabric is stretched in the warp direction. It is suppressed. In this way, the first and second inelastic yarns control the positions of each other, whereby the vertical and horizontal elongations are controlled well.

  Further, in the stretchable region other than the stretch control region, in order to ensure stretchability, for example, the structure of the first inelastic thread and the structure of the second inelastic thread are the same and / or the first In the inelastic yarn and the second inelastic yarn, the maximum swing width for each course and every two courses is preferably 3 stitches or less, for the following reason. That is, if the structure of the first inelastic thread and the structure of the second inelastic thread are the same, the first inelastic thread and the second inelastic thread may exert an action of controlling the expansion of each other. Therefore, sufficient stretchability can be ensured, and according to this configuration, there is an advantage that the texture of the structure of the first inelastic yarn and the structure of the structure of the second inelastic thread are the same. In the first inelastic yarn and the second inelastic yarn, when the maximum swing width for each course and every two courses is 3 stitches or less, as in the first inelastic yarn in the extension control region, the horizontal direction Therefore, the above-described elongation control action does not occur, and sufficient stretchability can be ensured, and a knitted fabric with high design like a mesh can be formed.

The structure C is a structure for imparting good stretchability to the stretch warp knitted fabric, and the structures O and P are structures for obtaining a stretch warp knitted fabric having a hem that does not require edge treatment.
Other organizations may be employed according to various other purposes.
Hereinafter, the structures A to C, O, and P will be described in detail together with specific examples.
<Organization A>
The tissue A is formed by the first inelastic yarn.
In the tissue A, in the extension control region, the first inelastic yarn is alternately swung left and right with a swing width of 4 to 7 needles every course and / or every two courses. The swing width is more preferably 5 to 7 needles, and further preferably 6 or 7 needles.

Here, “and / or” is not only one of the case where the left and right are alternately shaken for each course and the case where the left and right are alternately shaken for every two courses in one extension control region. Means that it may be mixed.
The structure A in the stretch region can adopt the same structure as a general stretch warp knitted fabric, but for the reason described above, it is the same structure as the stretch region of the structure B described later, and / or The first inelastic yarn and the second inelastic yarn described later preferably have a maximum swing width of 3 stitches or less for each course and every 2 courses.
Here, “the maximum swing width for each course and every two courses is 3 needles or less” means that the swing is the largest in both the swing width for each course and the swing width for each course. This means that the swing width is less than or equal to the needle, and as long as this is satisfied, the swing width may be greater than or equal to 4 needles, for example, when viewing each course of 3 or more courses. Moreover, the case where it forms on the same wale is also included.

A plurality of organizations A can be provided. As the plurality of tissues A, for example, two tissues composed of repeating units that oppose each other may be formed as a half set, or a plurality of full set tissues may be combined. In the present specification, when a plurality of tissues A are described, regardless of whether they are a half set or a full set, they are indicated as tissues A1, A2,.
As the organization A, for example, the organization shown in FIGS. 1A to 1C are examples of a half set, and FIGS. 3D and 3E are examples of a full set.
Specifically, in the stretchable region X, the structure shown in FIG. 3A is a repeating unit of 23/21/23/32/34/32 //, and the structure A2 shown by a broken line is 32 in the stretchable region X. / 34/32/23/21/23 //, and in the elongation control region Y, the tissue A1 is 10/23/45/32 // and the tissue A2 is 45/32/10/23. // Repeating unit. In this stretchable region X, the maximum swing width for each course and every two courses is two needles in both the structure A1 and the structure A2. In the extension control region Y, both the tissue A1 and the tissue A2 are alternately swung left and right every two courses, and the swing width is 5 needles.

In the stretchable region X, the tissue shown in FIG. 3B is a repeating unit of 23/21/23/32/34/32 // in the stretched area X, and the tissue A2 shown in the broken line is 43/45/43 /. 34/32/34 // repeating unit, and in the elongation control region Y, the tissue A1 is a repeating unit of 10/23/56/43 // and the tissue A2 is a repeating unit of 56/43/10/23 // It is. In this stretchable region X, the maximum swing width for each course and every two courses is two needles in both the structure A1 and the structure A2. Further, in the extension control region Y, the tissues A1 and A2 are alternately swung left and right every two courses, and the swing width is 6 needles.
In the stretchable region X, the structure shown in FIG. 3C is a repeating unit of 23/21/34/32/34/21 // in the stretched area X, and the structure A2 shown in the broken line is 32/34/21 /. It is a repeating unit of 23/21/34 //, and in the elongation control region Y, the tissue A1 is a repeating unit of 10/23/45/32 //, and the tissue A2 is a repeating unit of 45/32/10/23 // It is. In this stretchable region X, the maximum swing width for each course and every two courses is 3 needles in both the structure A1 and the structure A2. In the extension control region Y, both the tissue A1 and the tissue A2 are alternately swung left and right every two courses, and the swing width is 5 needles.

The structure shown in FIG. 3D is a repeating unit of 21/34 // in the expansion / contraction region X, and a repeating unit of 45/10 // in the extension control region Y. In this stretchable region X, the maximum swing width for each course and every two courses is three needles. Further, in the extension control region Y, each course is alternately swung left and right, and the swing width is 5 stitches.
The structure shown in FIG. 3E is a repeating unit of 21/34 // in the stretchable region X and a repeating unit of 56/43/10/23 // in the extension control region Y. In this tissue, the stretchable region X is common to the tissue shown in FIG. 4D, and in the extension control region Y, the left and right are alternately swung every two courses, and the swing width is 6 needles.

As the inelastic yarn used for the structure A, basically the same as a normal warp knitted fabric can be used. The non-elastic yarn is not limited to a yarn having no elasticity at all, but may be any yarn that is less elastic or stretchable than the elastic yarn. Specifically, in the present invention, the inelastic yarn means a yarn having an elongation of less than 60%. A yarn having an elongation of less than 40% is preferable.
As the inelastic yarn, for example, natural fibers such as cotton, synthetic fibers such as nylon, semi-synthetic fibers, regenerated fibers, and the like can be used, and in the form of filament yarns, spun yarns, twisted yarns made of these fibers, and the like. Can be used.
The thickness of the inelastic yarn is preferably 17 to 85 dtex, and more preferably 22 to 44 dtex. The inelastic yarn preferably has a thickness that can be covered so that the elastic yarn is not exposed on the surface of the knitted fabric. In addition, if it is as thin as possible and has strength (strength of about 200 kPa on the basis of the fabric), a thin warp knitted fabric can be easily manufactured. If the non-elastic yarn is too thick, the stretchability of the fabric is deteriorated, the surface texture and the touch are also deteriorated, and fraying is likely to occur.

In the present invention, “hot” refers to the phenomenon of fluffing or running that occurs on the cut end face when the elastic warp knitted fabric is cut at the beginning or end of knitting, and in any direction including an oblique direction or a curve. It is a general meaning.
<Organization B>
The tissue B is formed by the second inelastic yarn.
In the stretch control region, the tissue B forms a stitch and / or is inserted without exceeding the range of two needles over the entire course of the stretch control region. Preferably, the stitches are formed and / or inserted on the same wale over the entire course of the extension control region.

Further, the structure B in the stretchable region may adopt the same structure as a general stretchable warp knitted fabric, but the second inelastic yarn is the same structure as the structure A for the reasons described above. It is preferable that the second inelastic yarn and the first inelastic yarn have a maximum swing width of 3 stitches or less for each course and every 2 courses.
As the organization B, specifically, for example, the organization shown in FIGS.
The structure shown in FIG. 4A is a repeating unit of 12/10/12/21/23/21 // in the stretchable region X, and is a repeating unit of 21/12 // in the extension control region Y. . In this stretchable region X, the maximum swing width for each course and every two courses is two needles. In the extension control region Y, stitches are formed on the same wale over the entire course of the extension control region Y. In addition, since the structure | tissue of the said expansion-contraction area | region X is the same as the structure | tissue A2 in the expansion / contraction area | region X shown to Fig.3 (a), the combination with the structure | tissue shown to Fig.3 (a) is suitable.

  The structures shown in FIGS. 4B and 4C are examples in which the repeating unit of the extension control region Y is changed in the structure shown in FIG. That is, the repeating unit of the extension control region Y is 12/22/21/11 // in the structure shown in FIG. 4B and 11/22 // in the structure shown in FIG. In the stretch control region Y, stitches are formed on every other course on the same wale over the entire course of the stretch control region Y in the tissue shown in FIG. 4B, and in the tissue shown in FIG. 4B, the stretch control region Y is formed. All courses are inserted on the same wale. Note that the structure shown in FIGS. 4B and 4C is preferably combined with the structure shown in FIG. 3A in the same manner as the structure shown in FIG.

  The structures shown in FIGS. 4D to 4F are examples in which the repeating unit of the stretchable region X is changed to 23/10 // in the structures shown in FIGS. 4A to 4C, respectively. That is, the repeating units of the elongation control region Y in the tissues shown in FIGS. 4D to 4F are 10/01 //, 01/11/10/00 //, and 00/11 //, respectively. (Since the numbers are assigned sequentially from between the rightmost needles, there is a shift of one stitch from the tissue shown in FIGS. 4A to 4C, but the tissue is the same). In the stretchable region X, the maximum swing width for each course and every two courses is three needles. Since the structure of the stretchable region X is the same as that of the stretchable region X shown in FIGS. 3D and 3E, a combination with the structure shown in FIG. 3D or 3E is preferable. .

The structure B is a structure made of the second inelastic thread. As the second inelastic thread, basically, the elongation and material common to the first inelastic thread described in the structure A are used. The thickness can be adopted.
<Organization C>
The structure C imparts good stretchability in the vertical and horizontal directions to the stretchable knitted fabric.
Specifically, for example, a structure having a repeating unit such as 00/11 // 10/12 // can be adopted as the structure C.
The structure C is a structure made of elastic yarn, and the material of the elastic yarn can be the same as the elastic yarn used in a normal stretch warp knitted fabric. For example, polyurethane elastic yarn can be used. A highly elastic polyurethane yarn known as spandex can be used. A coated elastic yarn obtained by coating an elastic yarn with an inelastic yarn can also be used.

An elastic yarn having an elongation of 100% or more can be used. Preferably, the elongation is 300% or more.
The thickness of the elastic yarn is preferably 44 to 1240 dtex.
<Organization O>
Tissue O constitutes the end of the thread or hem.
Specifically, for example, a structure having a repeating unit such as 01/10 // 10/10 // can be adopted as the structure O.
The structure O is a structure made of an inelastic thread. As the inelastic thread, basically, the elongation and material common to the first inelastic thread described in the structure A can be adopted. However, the thickness of the inelastic yarn is preferably 33 to 200 dtex for the drawn yarn and 15 to 55 dtex for the hem portion.

<Organization P>
In the stretch warp knitted fabric before separation, the structure P fulfills a function of connecting the drawn yarn portion and the unit knitted fabric on both sides thereof. After the elastic warp knitted fabric is separated by the drawing yarn portion, it is integrated with the hem ends of the unit knitted fabric on both sides.
As a specific structure, a structure similar to a stretchable warp knitted fabric having a normal separation structure can be adopted. For example, it is possible to employ a structure in which both unit knitted fabrics and the drawn yarn portions are inserted alternately or every several courses. Specifically, as the structure P, for example, a structure having a repeating unit such as 11/33/11/22/00/22 //, 22/55/22/33/00/33 // can be employed.

An elastic connective structure is disposed between the unit knitted fabrics on both sides of the one drawn yarn portion. At this time, both elastic connective structures are structures independent from each other, and adopt a structure in which each elastic connective structure is divided and drawn to unit knitted fabrics on both sides when the drawn yarn is unwound.
By forming the elastic connecting structure with elastic yarns, the portion where the drawn yarn portions are connected when the elastic warp knitted fabric is separated is smoothly drawn to the unit knitted fabric on both sides.
As the elastic yarn used for the tissue P, basically, the elongation and material common to the elastic yarn described in the tissue C can be adopted. However, the thickness of the elastic yarn is preferably 88 to 560 dtex.

[Extension control area]
For example, a rigid part or a high power part can be preferably exemplified as the extension control region that can be formed by the tissue exemplified above.
Even in the same structure, for example, by changing the yarn supply amount or the yarn thickness, it is possible to change the degree of extension control in various ways, such as a rigid part or a high power part. be able to.
Hereinafter, each of the rigid portion and the high power portion will be described in detail.
<Rigid part>
In the present invention, the rigid portion refers to an extension control region in which the vertical and horizontal elongations at a load of 2.25 kgf (22.1 N) are each less than 30%. Such a rigid part is formed in a place where it is not preferable to easily expand and contract in clothing, such as a side of a brassiere or a front part (a valley of a cup).

<High power section>
In the present invention, the high power part is an elongation control region in which the elongation of at least one of vertical and horizontal at a load of 2.25 kgf (22.1 N) is 30% or more, It indicates the elongation within 50% vertical and 80% horizontal. Such a high power part is formed in a garment at a place where it is desired to provide power by controlling elongation, for example, at the side of a brassiere, the waist part of a pant, or the front part.
[Knitting of elastic warp knitted fabric]
When knitting the elastic warp knitted fabric according to the present invention, a normal knitting apparatus and knitting method can be applied.

The warp knitting machine is not particularly limited, and for example, a tricot knitting machine, a Russell knitting machine, a jacquard knitting machine, or the like can be used.
The knitted stretch warp knitted fabric becomes a stretch warp knitted fabric product through processing steps performed on a normal stretch warp knitted fabric such as set processing, scouring treatment, and dyeing treatment.

Hereinafter, the present invention will be described more specifically with reference to Examples and Comparative Examples, but the present invention is not limited to these.
As the knitting device, RSE6EL manufactured by KARL MAYER was used.
In Examples 1 and 2 and Comparative Example 1, the warp and width elongation of the elastic warp knitted fabric is measured by the following measurement method.
<Vertical and horizontal elongation>
2.5 cm x 16.0 cm test pieces were taken in the vertical and horizontal directions, and these test pieces were stretched at a constant speed with an upper grip of 2.5 cm, a lower grip of 3.5 cm, and a grip interval of 10.0 cm. Attached to a mold tensile tester, the machine was operated at a speed of 30 ± 2 cm / min, and the elongation (%) of each of the first vertical and horizontal was measured when pulled with a load of 2.25 kgf (22.1 N). .
