Description

  The present invention relates to a warp knitted fabric, and more particularly, to a warp knitted fabric that can be suitably used for clothing intended for body shape correction by forming a region with high power partially.
Conventionally, warp knitted fabrics in which power is partially increased for the purpose of body shape correction or the like are known.
As methods for partially increasing the power, methods such as partially applying a cloth or partially changing a knitted structure are known. In the method of applying a partly applied cloth, a step occurs in the applied part, and the appearance and wearing feeling are impaired. Therefore, it is better to strengthen the power by partial change of the knitted structure without such a step. ing.
As a power strengthening technique by partial change of the knitting structure as described above, it is known to use a change in structure by the jacquard structure. For example, a ground knitting made of jacquard knitting is knitted with inelastic yarn and inserted. In a garment composed of warp knitted fabric using elastic yarn as the yarn, the knitting structure appearing on the front side of the ground knitting is switched according to the demand for the strength of the tightening force, and a predetermined relatively tight tension is applied to a predetermined portion due to a change in the structure. A technique relating to a garment having a body shape correction function made of a warp knitted fabric in which a strong portion and a relatively weak force portion are provided in a pattern is known (see Patent Document 1).
Conventionally, as described in Patent Document 1, it has become common knowledge to use an inelastic yarn as a yarn to be used in a jacquard structure. However, since an inelastic yarn does not have stretchability, the wearer Depending on the shape of the body and the movement of the wearer's body, there is a case where a tight feeling as if pressed down is generated.
Although it is not a technology aimed at strengthening the power by utilizing the structural change caused by the jacquard structure, elastic yarn is used for the jacquard heel, and inelastic yarn is used for the front heel located in front of the jacquard heel. There is also known a warp knitted fabric characterized by a looped structure with swinging and a pattern formed by a jacquard motion of the elastic yarn (see Patent Document 2). This technique is intended to provide a warp knitted fabric that has a delicate pattern and good stretchability and is thin.
  However, the warp knitted fabric obtained by the technique of Patent Document 2 has a looping structure made of inelastic yarn on the fabric surface and a jacquard structure made of elastic yarn on the back of the fabric, and the jacquard pattern appears to sink. . Patent Document 2 also describes that the pattern of the knitted fabric is mainly characterized in that the pattern is formed mainly by deformation of the sinker loop of the inelastic yarn by the elastic jacquard mechanism. Yes, as can be seen from this description, the pattern is formed by indirectly changing the looping structure of the non-elastic yarn provided on the fabric surface by the change in the structure of the jacquard structure by the elastic yarn provided on the back of the fabric. The pattern forming mechanism is different from that of a normal jacquard structure, and it is difficult to apply as a general jacquard warp knitted fabric.
In order to solve the problem, in the technique of Patent Document 2, when a jacquard structure made of elastic yarn is provided on the fabric surface, it is easily embrittled by light, heat, etc., fastness is poor, and dyeability is poor. There arises a new problem that the knitting property is poor (thread breakage is liable to occur when a loop is formed), and the product is easily worn out when worn.
Japanese Patent No. 3461316 JP 2002-371453 A
  Therefore, the problem to be solved by the present invention is that even if the jacquard structure is arranged on the fabric surface, the embrittlement hardly occurs, the fastness, the dyeability, and the knitting property are good. It is a warp knitted fabric that does not easily wear out at times, and has a high level of elasticity while partially having high power, and it has an excellent feeling of wear that is not easily influenced by the wearer's body shape, and supports the movement of the wearer's body. It is to provide a warp knitted fabric having the following ability to obtain.
The present inventor has intensively studied to solve the above problems. As a result, if the jacquard structure is formed by the covered elastic yarn, the above-mentioned problems such as fastness and dyeability as in the jacquard structure by the elastic yarn do not occur, and it is difficult to be influenced by the wearer's body shape. A warp knitted fabric having a feeling of wear and a follow-up that can correspond to the movement of the wearer's body can be obtained, and this warp knitted fabric is a novel that is not in the case of forming a jacquard structure with inelastic yarns. The present invention has been completed by finding out that it has the property, that is, the property that the power can be increased by the amount of expansion and contraction and the power can be changed by the thickness of the yarn.
That is, the warp knitted fabric according to the present invention is composed of at least a combination of a jacquard structure arranged on the fabric surface and a supporting structure thereof, and a high-power region is partially formed only by a structure change of the jacquard structure. The warp knitted fabric is characterized in that the jacquard structure is composed only of covered elastic yarns.
  The warp knitted fabric according to the present invention is resistant to embrittlement even when the jacquard structure is arranged on the fabric surface, and has good fastness, dyeability, and knitting property. It is also a warp knitted fabric that is less likely to occur, and has an excellent wearing feeling that is difficult to be influenced by the wearer's body shape, and can follow the movement of the wearer's body, and can increase power by the amount of expansion and contraction, It also has the property that non-elastic yarn can change power with the thickness of the yarn.
Hereinafter, the warp knitted fabric according to the present invention will be specifically described. However, the scope of the present invention is not limited to these descriptions, and modifications other than the following examples can be made as appropriate without departing from the spirit of the present invention.
[Warp knitted fabric]
The warp knitted fabric according to the present invention is a warp knitted fabric comprising a combination of at least a jacquard structure and a support structure, and a high-power region is partially formed by a structural change of the jacquard structure. The tissue consists of coated elastic yarn.
[Jacquard organization]
The jacquard organization is knitted by the jacquard cage, and various knitted organizations can be formed by displacing the basic operation of the jacquard cage.
The jacquard structure according to the present invention is characterized in that it is formed by coated elastic yarns, and the basic operation and displacement mechanism of the jacquard ridge may be the same as in the past.
For example, as in a normal jacquard structure, a thick knitted fabric in which yarns are knitted across two adjacent wales in a polymerized manner, a thin knitted fabric knitted across only one side between wales, and a knitted fabric It is possible to form a hole knitted fabric in which yarns do not cross between the wales entangled with one wal.
And a high power area | region can be partially formed by knitting a jacquard structure | tissue basically with a thin ground knitting and a part with a thick ground knitting.
Further, similarly to a normal jacquard structure, a pattern can be formed by combining the thick knitted fabric, the thin knitted fabric, and the perforated knitted fabric.
Next, the coated elastic yarn forming the jacquard structure according to the present invention has a structure in which the elastic yarn is coated with the coated yarn.
The elastic yarn of the coated elastic yarn is not particularly limited, and for example, spandex such as polyurethane elastic yarn generally used conventionally can be used. In addition, as the covering yarn, natural fibers such as cotton, synthetic fibers such as nylon, and non-elastic yarns such as semi-synthetic fibers and regenerated fibers can be used. It is also possible to use yarns other than the non-elastic yarns having elastic elasticity.
The coated elastic yarn is not limited to one elastic yarn covered with one coated yarn (single-covered yarn), but one elastic yarn covered with two coated yarns ( Double covered yarn).
The thickness of the coated elastic yarn is preferably 11 to 98 dtex, for example. If it is this range, cloth | dough will not become thick too much and moderate elasticity can be provided.
The thickness of the elastic yarn of the coated elastic yarn is preferably 78 dtex or less, for example. If it is 78 dtex or less, the cloth will not be too thick and appropriate stretchability can be imparted. More preferably, it is 33-44 dtex. In particular, according to this covered elastic yarn, the power can be changed according to the thickness of the elastic yarn. An inelastic yarn can provide only a fixed power corresponding to the length of the yarn, and the power cannot be changed according to the thickness of the yarn.
The thickness of the coated yarn is preferably 0.3 times or more, for example, with respect to the thickness of the elastic yarn. If it is 0.3 times or more, the elastic yarn is easily embrittled by light or heat, fastness, dyeability, low knitting property, and easily worn when worn. It is possible to sufficiently eliminate such drawbacks. More preferably, it is 0.7 to 1.4 times.
[Supporting organization]
The support structure is basically formed of inelastic yarns, stabilizes the physical properties of the warp knitted fabric, and may be a structure in which inelastic yarns and elastic yarns are combined.
The supporting structure is not particularly limited, and those usually used together with a jacquard structure can be adopted. For example, 10/12/23/21 //, 10/12/10/23/21/23 //, and having a repeating unit such as 12/12/12/10/10/10 //.
As the inelastic yarn, natural fibers such as cotton, synthetic fibers such as nylon, semi-synthetic fibers and regenerated fibers can be used. Any form such as a filament yarn, a spun yarn, and a twisted yarn composed of these fibers may be used.
The thickness of the inelastic yarn is not particularly limited, but is preferably 17 to 85 dtex, for example. More preferably, it is 22-44 dtex. Within the above range, it is possible to impart good stability to the knitted fabric without causing problems such as thickening of the fabric, impairing stretchability, and deterioration of the surface texture and touch. it can.
When an elastic yarn is also combined as a support structure, the thickness of the elastic yarn is not particularly limited, but is preferably 33 to 156 dtex, for example. More preferably, it is 33-78 dtex. If it is in the said range, the stretchability excellent in the knitted fabric can be provided, without producing problems, such as material | dough becoming thick and the surface texture and the touch falling.
(Insertion thread)
In the warp knitted fabric according to the present invention, it is preferable to combine an insertion yarn made of an elastic yarn. By inserting the elastic yarn, the stretchability becomes better.
The thickness of the elastic yarn is not particularly limited, but is preferably 33 to 622 dtex, for example. More preferably, it is 44-310 dtex. If it is in the said range, the stretchability excellent in the knitted fabric can be provided, without producing problems, such as material | dough becoming thick and the surface texture and the touch falling.
[Other knitting structures and yarns]
In the warp knitted fabric according to the present invention, in addition to the above-mentioned jacquard structure, support structure, and insertion yarn, other knitting structures and knitting yarns as employed in ordinary knitted fabrics may be applied.
For example, a separation structure that does not require edge trimming may be provided by a conventionally known method using a drawn thread or an elastic connecting structure.
[Manufacture of warp knitted fabric]
For knitting, basically, a knitting device and a knitting method common to ordinary knitted fabrics can be applied.
The knitting machine is not particularly limited as long as it is a knitting machine having a jacquard mechanism, and various conventionally known knitting machines can be used.
Usually, a ridge that forms a supporting structure is arranged behind a jacquard ridge that forms a jacquard knitted structure. That is, usually, a jacquard structure is provided on the fabric surface of the warp knitted fabric, and a support structure is provided on the back of the fabric. In the present invention, since the jacquard structure is formed of the coated elastic yarn, as described above, even if the jacquard structure is provided on the fabric surface, it becomes easy to become brittle, and the fastness, dyeability, and knitting property are deteriorated. There is no problem of wearing out or fraying when worn.
The knitted knitted fabric becomes a knitted fabric product through processing steps performed on a normal knitted fabric such as a scouring process, a set process, and a dyeing process.
In particular, when two or more types of elastic yarns are used and crossed or looped, at the time of set processing, the elastic yarn is thermally fused at the crossing portion or the stitch portion of the yarns and joined, The resistance to tearing can be increased and the bursting strength can be improved. The processing conditions for the set processing in this case differ depending on the types and characteristics of the inelastic yarn and elastic yarn to be used, but usually heat setting processing at 180 to 195 ° C. is employed.
[Use]
The warp knitted fabric according to the present invention can be suitably used for clothing intended for body shape correction, for example, and can be suitably used not only for inner garments but also for sportswear by taking advantage of its stretchability.
Hereinafter, the warp knitted fabric according to the present invention will be specifically described with reference to examples, but the present invention is not limited thereto.
As a knitting device, RSJ5 / 1 manufactured by KARL MAYER was used.

The operation of attaching to a mold tensile tester and applying 80% of the test piece at a speed of 30 ± 2 cm / min to elongate 80% and then returning the extension at a speed of 30 ± 2 cm / min while relaxing the load on the test piece. During cycling and testing, the power (stress generated on the specimen) was automatically measured and recorded.
Note that 80% elongation of the above-mentioned test piece is (de) from the length (grip interval) e of the test piece before being stretched and the length d of the test piece in the stretched state in the stretched state. This means that the value obtained by / e × 100 is 80%. The following numerical values are given in the same way for 15% elongation, 30% elongation, and 50% elongation, and the elongation values described below are also based on the same calculation formula.
Table 1 shows the power at load (L), power at unloading (UL), and power at 80% extension at 15% extension, 30% extension, 50% extension at the third cycle (3rd), It was shown in 2.
<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 first (1st) vertical and horizontal elongation (%) when pulled at a load of 9.8 N was measured. Similarly, the elongation (%) of each of the first (1st) warp and width when pulled with a load of 14.7 N and a load of 22.1 N was also measured.
Tables 1 and 2 show the elongation for each load.
<Extension recovery>
In the same manner as in the power measurement, the test piece was attached to a constant speed extension type tensile tester, and 80% extension and recovery were repeated 3 cycles at a speed of 30 ± 2 cm / min. At this time, the length (%) after recovery in the first cycle (1st) and the third cycle (3rd) with respect to before the extension was measured. This value is used as an evaluation criterion for elongation recovery.
The elongation recovery properties are shown in Tables 1 and 2.
[Consideration of results]
As can be seen by comparing the knitted fabric according to the example shown in Table 1 and the knitted fabric according to the comparative example shown in Table 2, the knitted fabric according to the example has the power in the power reinforcement portion in the comparative example. It is similar to such a conventional knitted fabric, and can be sufficiently applied for purposes such as body shape correction.
In particular, when paying attention to power at 30% extension and 50% extension, the knitted fabric according to the example has a power at unloading of 50% or more with respect to the power at the load. On the other hand, it can be seen that in all the knitted fabrics according to the comparative examples, the power during unloading is 50% or less of the power during loading. This means that the knitted fabric according to the example has a high return force, and because it exhibits excellent power both at the time of extension and at the time of return, it corresponds to the movement of the wearer's body. On the other hand, the knitted fabric according to the comparative example can give power only at the time of extension, and the manner in which the force is applied to the wearer is fixed. It can be seen that the followability that can correspond to the movement of the wearer's body is not exhibited.
Furthermore, while the knitted fabric according to the example gives sufficient power to the power reinforcement portion, the elongation of the power reinforcement portion is not significantly different from the elongation of the body fabric portion, and has a partly high power. However, it is supported that the object of the present invention of being rich in stretchability is achieved. On the other hand, in the conventional knitted fabric according to the comparative example, it can be easily estimated that the elongation of the power reinforcement portion is small and the wearer will be cramped.
With regard to the stretch recovery property, in any of the knitted fabrics according to the examples, the stretch recovery property in the power reinforcement portion shows a high value exceeding 90% in both the first time and the third time.
  The warp knitted fabric of the present invention can be suitably used, for example, as an inner garment or sportswear intended for body shape correction or the like.
