Description

Specification

Warp knitted lace for brassiere

Technical field

[0001] The present invention relates to a warp knitted lace fabric used for a brassiere, and more particularly to a warp knitted lace fabric that can be used as it is for at least a back cloth of a brassiere.

Background art

[0002] Traditionally, knitted laces have been used for ladies' bras, foundations such as shorts and girdles, lingerie and other women's underwear such as slips and camisoles, and various clothing such as sportswear and outerwear. in use.

[0003] In a brassiere, the race ground is used in combination with other materials mainly in the cup part. However, in the case of a so-called back cloth that reaches both sides of the cup part and the back part through the side parts. The warp knitted lace is mostly used!

[0004] That is, in the back fabric of a brassiere, in many cases, a plain fabric such as a knitted fabric is used with emphasis on functionality, and if necessary, the fabric is used in combination with other stretch fabrics. The decoration is not important. In addition, in order to secure a tightening force, it has been proposed to use a stretchable knitted fabric having a large stretchability (power) in necessary parts such as upper and lower edges (Patent Document 1). After all, it is just a plain knitted fabric, and the decorative effect of the back cloth is hardly expected.

[0005] Further, the back cloth of a brassiere is often sewn with the cup side wide and the back end narrow. Therefore, when using the above-mentioned stretch warp knitted fabric, it is knitted according to the width on the cup side, and the side edge on the back side is cut and edge processed and sewn, or as in Patent Document 1. In addition, a V-shaped cut is made on the back side to sew, and sewing force is required to make a backing cloth.

[0006] Note that, in some cases, the above-mentioned lace ground is also used for the edge decoration of a back cloth. However, in that case, at least one side edge of the lace ground is cut, so that the side edge frays. Processing for prevention is required, and processing such as sewing with other fabrics is also required. Patent Document 1: Japanese Patent Laid-Open No. 2002-339110 Disclosure of the invention

Problems to be solved by the invention

[0007] The present invention has been made to solve the above-described problems, and can be suitably used as it is for a back cloth of a brassiere or the like without requiring treatment of both side edges after separation from the side fabric. It is intended to provide warp knitting lace.

Means for solving the problem

[0008] The warp knitted lace fabric for a brassiere according to the present invention that solves the above-mentioned problems is knitted by a warp knitting machine, and patterned yarns are knitted in a predetermined pattern, and both side edges separated from the side fabric are provided. This is a warp knitted lace fabric used for a brassiere that is formed without any treatment, and the width in the knitting direction changes for each unit length according to the back cloth of the brassiere. Is formed continuously as a wide area portion including the maximum width position and a region on the other end side as a narrow area portion including the minimum width position, and the ratio of the maximum width (W1) to the minimum width (W2) ( W1ZW2) is 1.5 to 10, and the wide region portion is formed as a side portion in the back cloth as a back portion in the narrow region partial force S back cloth.

[0009] This warp knitted lace fabric is cut from the side fabric after knitting, and then cut into unit lengths according to the knock cloth of the brassiere to prevent fraying and sewing on both side edges. Without being connected, it can be used as it is by connecting it to the cup as a back cloth of a brassiere, and the decorative effect of the knock cloth can be enhanced.

[0010] Further, since the ratio (W1ZW2) of the maximum width (W1) to the minimum width (W2) is set as described above, the wide region portion is connected or continuously formed with the cup portion. The necessary width can be secured, and the width of the narrow area that becomes the back part of the back cloth can be narrowed to such an extent that the strength and appearance in use are not impaired.

[0011] In the above-mentioned warp knitted lace fabric for a brassiere, the width varies in the knitting direction for each unit length corresponding to the combined length of the brassiere cup portion and the knock fabric continuous thereto, The wide region portion on one end side in the knitting direction and the narrow region portion on the other end side are continuously formed, and the wide region portion is continuous with a portion corresponding to the cup portion of the brassiere. Also knitted to form a part corresponding to the side of the back cloth Can be. As a result, the brassiere cup portion and the back cloth can be formed integrally without requiring sewing or the like, and a higher decorative effect can be exhibited.

[0012] The warp knitted lace fabric is particularly preferably used for a force bra that has a minimum width (W2) iS of 20 mm or more and 100 mm or less of the narrow area portion.

[0013] In the above-described warp knitted lace fabric, the knitted fabric is a lace fabric in which stretchable yarns are provided and stretchability is imparted, and the stretchable yarns are partially stretchable by changing the properties of the stretchable yarns. It is preferable that the is changed. As a result, by using this warp knitted lace fabric for the knocker cloth of the brassiere (which may include a cup portion), a sufficient tightening force can be secured even when the lace fabric is used alone.

[0014] In particular, when fray-preventing yarns are knitted as one of the edge-constituting yarns on both side edge portions of the warp knitted lace fabric, the both side edges remain separated from the side fabric. Even if it is not treated, it can be used as a back cloth for brassiere without any risk of fraying.

The invention's effect

[0015] According to the warp knitted lace fabric for a brassiere of the present invention, it is not necessary to treat both side edges after being separated from the side fabric, and is used as it is on the back fabric of the brassiere alone or on the cup portion and the back fabric. It is possible to reduce the labor required for sewing work for brassiere production and enhance the decorative effect of the knock cloth.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, embodiments of the present invention will be described based on examples shown in the drawings.

[0017] Fig. 1 is a schematic plan view showing an embodiment of a warp knitted lace fabric of the present invention, Fig. 2 is a schematic plan view showing the production state of the warp knitted race fabric, and Fig. 3 is a warp knitted fabric. FIG. 4 is a schematic perspective view showing an example used for a back cloth of a brassiere, and FIGS. 5A to 5E are schematic views showing examples of changes in the planar shape of a warp knitted lace fabric. FIG.

[0018] In Fig. 1, reference numeral 1 denotes a warp knitted fabric according to the present invention knitted by a warp knitting machine. A warp knitting machine having a plurality of (typically several dozen) handle knives for knitting a knitted fabric, and, further, by controlling the movement of the guide needle with a jacquard device separately from the handle heel Hole, thin ground, thick ground, etc. It is knitted by a warp knitting machine equipped with at least one jacquard guide rod forming a lace pattern.

In the warp knitted lace fabric 1 of the embodiment shown in FIGS. 1 to 4, pattern yarn (not shown) is knitted while forming a stitch with a predetermined pattern, or is inserted and knitted. The warp knitted race 1 has a lace pattern and a relatively large handle portion 2 formed by the handle yarn, and curved and wavy scallops 5 are formed on both side edges 3 and 4. . For the side edges 3 and 4, the scallop 5 is not necessarily required to be continuously formed over the entire length of the side edge. In some cases, the side edge shape does not have scallops, for example, a straight or large curved shape.

[0020] Both side edges 3, 4 of the warp knitted lace fabric 1 are connected to the lace fabric 1 by a connecting thread (not shown), for example, a side fabric such as an ear or the warp knitted lace. It is formed so that it can be used without any edge treatment in a state separated from other warp knitted laces that are knitted in parallel with the ground 1. As a means for this, for example, the edge-constituting yarn 6 composed of the edge pattern yarn 6a or the like is inserted and knitted into the ground structure over the width of one wale or a plurality of wales at the both side edges 3 and 4. It is trimmed by knitting or knitting while forming a ridge or stitch. More preferably, as one of the edge-constituting threads 6, a fraying prevention thread 6b is knitted while forming a stitch along the side edge separately from the edge pattern thread 6a, etc. It is formed so that fraying does not occur even when separated from the dough. As the edge constituting yarn 6, an elastic yarn (not shown) may be knitted in addition to the above yarn.

[0021] In the warp knitted lace fabric 1 of the present invention, at least one of the side edges 3 and 4, for example, both sides as shown in the figure, the edge structure of the edge pattern yarn 6a, fray prevention yarn 6b, etc. When the thread 6 is formed along the edge shape, for example, when forming the scallop 5, along the shape of the scallop 5, the yarn 6 moves over one wale or a plurality of whales and is applied to the back cloth of the brassiere. For each unit length L1, the side edges 3 and 4 are slanted so that the lateral length gradually shifts in the lateral direction over several tens of wales or more between the unit lengths L1. As a result, the knitting width of the lace fabric 1 is changed in the knitting direction, whereby the required length on one end side in the knitting direction in the range of the unit length L1. As the wide region portion 11 where the region includes the maximum width position PI and the required length region on the other end side in the range as the narrow region portion 12 including the minimum width position P2, the average width within the unit length L1 is mainly used. Are formed continuously through the portion 13. The average width portion 13 is not necessarily in the middle of the length direction.

[0022] In particular, the knitting in which the wide region portion 11 and the narrow region portion 12 are made continuous by changing the knitting width as described above is performed, for example, as follows.

[0023] The knitting width is changed by the transition of the edge constituting yarn 6 for each repeat length L0 of the pattern or the ground knitting in the knitting direction set in accordance with the unit length L1, and as shown in FIG. As described above, by repeating the knitting to gradually reduce the width and then gradually increase the width in the opposite direction, the wide region portion 11 and the narrow region portion 12 are continuously formed repeatedly, Form a long race 1 Then, after the knitting, the unit length L1 at the intermediate point in the knitting direction of the wide area portion 11, for example, the maximum width position P1, and the intermediate point in the knitting direction of the narrow area portion 12, for example, the minimum width position P2. By cutting each of the two races, each of the divided wide region portions 11 is on the end side, the divided narrow region portion 12 is on the other end side, and has the unit length L1. A ground part is obtained. For this reason, the length of one repeat of the pattern or ground knitting is 1Z2 length force of the one repeat length of the one repeat so that the unit length L1 corresponds to the back cloth 20 of the one brassiere B LO is set.

[0024] In the lace portion of each unit length L1 obtained in this way, the wide region portion 11 serves as the side portion 21 in the left and right back cloth 20 of the brassiere B, and the narrow region portion 12 includes It is formed as a back portion 22 continuous from the side portion 11. That is, at least one side edge, for example, the required portions of the side edges 3, 4 as shown in the figure as a whole are straight and Z or Z, so that the side edges 3, 4 form the upper and lower edges 23, 24 of the back cloth 20. It is slanted by a curved line, and is formed so as to have a shape corresponding to the above-mentioned back cloth 20 with 1Z2 of 1 repeat length LO as unit length L1.

[0025] It should be noted that the unit length L1 corresponding to the back cloth is set to a length corresponding to approximately one repeat of the pattern or the ground knitting, and one of the knitting start side and the knitting end side of one repeat is a wide region portion 11 Alternatively, knitting can be continuously performed alternately so that the other becomes the narrow region portion 12. In particular, the knitting start side of one repeat of the unit length L 1 is the minimum width position P2, and the knitting end side is the maximum width position PI. By knitting in an inclined manner, fraying of the partial force of the side edges 3 and 4 separated from the side fabric can be prevented from reaching the inside of the race.

[0026] Regarding the widths of the wide region portion 11 and the narrow region portion 12 in the warp knitted lace fabric 1, the width of the maximum width position P1, that is, the maximum width (W1) and the width of the minimum width position P2 That is, the ratio (W1ZW2) force to the minimum width (W2) is set to 1.5 to 10, preferably 2 to 6. Further, with respect to the minimum width (W2) of the narrow area portion 12, when using the back cloth 20 of the brassiere B, a locking tool such as a hook is attached to the narrow area portion 12 which becomes the back portion 22. In view of the strength and appearance in use, it is usually preferable to set it within a range of 2 Omm or more and 100 mm or less.

That is, when the ratio (W1ZW2) of the maximum width (W1) to the minimum width (W2) is smaller than 1.5, when the minimum width (W2) is set to a width in the preferred range, The wide region portion 11 used for the side portion 21 is not preferable because the width necessary for connection or continuous formation with the cup portion cannot be secured, or it becomes unnatural. On the other hand, if the ratio (W1ZW2) is larger than 10, when the width (W2) is set to the preferred range, the width of the wide region portion 11 becomes excessively large and unnatural. From the viewpoint of appearance and practical use, the ratio (W1ZW2) in the range of 2 to 6 is more preferable. In any case, the maximum width position P1 and the minimum width position P2 do not necessarily exist at the ends of the wide area portion 11 and the narrow area portion 12, respectively.

[0028] Regarding the inclined state of at least one of the side edges 3 and 4, that is, the width change state and the planar shape between the maximum position P1 and the minimum width position P2, there are various types according to the usage. Can be implemented. For example, as shown in FIGS. 1 to 4, the side edges 3 and 4 are slightly curved and inclined while forming a scallop 5, and the gap between the maximum width position P1 and the minimum width position P2 is between In addition to the shape of a flat, trapezoidal plane with the line at the maximum width position P1 as the base, one side edge 3 is made substantially straight in the knitting direction as shown in FIG. Inclined, as shown in Fig. 5B, in which both side edges 3, 4 are inclined in a curved shape, as shown in Fig. 5C, one side edge 3 is substantially straight, and the other side edge 4 is curved. Inclined, as shown in Fig. 5D, with the curved state of both side edges 3 and 4 changed, and as shown in Fig. 5E, both side edges 3 and 4 are provided with a substantially straight part in the knitting direction. Various implementations are possible. [0029] In any of the above cases, the outer shape that does not take into account the fine concavo-convex shape such as the scallop 5 on the both side edges 3, 4 will be described. In each of FIGS. 5A to 5E, the both side edges 3, 4 This includes the case where corrugations such as scallop 5 and uneven shapes are formed as necessary. In some cases, a portion having a slightly narrow width is formed in the wide region portion 11 or a portion having a slightly large width is formed in the narrow width region portion 12.

[0030] The edge constituting yarn 6 such as the edge pattern yarn 6a and the fray preventing yarn 6b constituting the both side edges 3 and 4 are extended over the entire length of the side edge, that is, from the maximum width position P1. In addition to knitting or insertion knitting while continuously forming the same yarn over the entire length including the narrow position P 2 without switching the heel, another heel is used during the transition corresponding to the inclined shape of the side edge. Although it is possible to switch to the same type of yarn and to perform knitting, in practice, it is preferable to perform knitting without switching to another yarn as described above.

[0031] That is, when the edge-constituting yarn forming the side edge of the lace is formed by knitting or inserting knitting while forming the same stitch continuously over the entire length of the side edge, This means that there is no need to have a changeover part! / ヽ, and it is necessary to keep extra yarn for changeover in the side edge as in the conventional case. It will be good. In addition, since there is no need to use a decorative heel for the above-mentioned switching, the number of pattern ridges that can be used for the pattern configuration is larger than that when the thread is switched, and the pattern with higher decorativeness is used. Can be formed.

[0032] Further, the warp knitted lace fabric 1 is not only knitted using only non-stretchable yarns, but also, if necessary, stretchable yarns such as polyurethane fiber yarns (for example, polyurethane fiber yarns) (Not shown) is arranged in the entire lace fabric, inserted into the knitted fabric without knitting, or knitted while forming the stitch, or knitted while forming the stitch, so that the entire knitted fabric is at least warped (knitting direction). ) Is given elasticity.

[0033] In this case, the elastic yarns arranged in the basic structure of the ground knitting! /, And the number and thickness of the elastic yarns are partially stretchable due to changes in characteristics depending on the type and the like. It can be changed. For example, in the use as the back cloth 20, the stretchability at the part of the required width from the both side edges 3, 4 that become the upper and lower edges 23, 24 to the inner side (the part up to the one-dot chain line in FIG. 1 etc.) Greater stretchability (stretching power) than inner part 9 due to changes in yarn characteristics It can be set as desired. As a result, it is possible to secure a tightening force when used as the back cloth 20. 7 and 8 in the figure indicate the stretchable change part between the side edges 3 and 4 and the one-dot chain line. The part that greatly changes the stretchability (stretching power) is provided along the side edges 3 and 4 as described above, and may be provided only on one side of the side edges 3 and 4, or the inner side. It can also be provided in part 9 and its width can be set arbitrarily.

[0034] As means for changing the stretchability, it is possible to partially change the thickness and type of the stretchable yarn itself, or by using a heel different from the stretchable yarn arranged on the entire ground fabric. It is also possible to knit by partially adding the elastic yarn to be arranged.

[0035] The warp knitted lace fabric 1 has the wide region portion 11 and the narrow region portion 12.

1Z2 of 1 repeat length or 1 repeat length is 1 unit length corresponding to the back cloth 20, and the change of the width is repeated and knitted into a long length. At this time, multiple rows are connected in the knitting machine width direction and knitted simultaneously. Then, after knitting, each row is separated, and the unit length is cut into a predetermined length corresponding to the back cloth 20 corresponding to the size of the brassiere B, as shown in FIG. In addition, the end on the wide region portion 11 side is connected to a cup portion 25 formed separately by sewing means, and a connecting member (not shown) such as a hook is connected to the end on the narrow region portion 12 side. ) Install and use.

FIG. 6 is a schematic plan view showing a warp knitted lace fabric of another embodiment including a portion corresponding to the cup portion, and FIG. 7 is a schematic perspective view showing an example of use of the warp knitted lace fabric.

[0037] In the warp knitted lace fabric 1 of this embodiment, the wide region portion 11 and the side portion 21 of the knock cloth 20 of the brassiere B form a portion 15 corresponding to the cup portion 25 continuous therewith. In this case, the center of the portion 15 corresponding to the cup portion is the maximum width position P1. Also in this embodiment, the portion 10 corresponding to the knock cloth 20 is configured in the same manner as in the above-described embodiment. The same components are denoted by the same reference numerals.

[0038] With respect to the portion 15 corresponding to the cup portion 25 in the wide region portion 11, the edge pattern yarn constituting both side edges 3 and 4 continuing from the portion 10 corresponding to the back cloth 20 is provided. The knitting width is changed so as to correspond to the shape of the cup portion 25 by the transition of the edge constituting yarn 6 such as 6a and the fray preventing yarn 6b. In addition, similar to the above embodiment, Stretch yarn is knitted as necessary to give stretch to the entire knitted fabric, and further knitted so as to keep large stretch elasticity (power) at the lower part or upper edge part of the chop Has been.

[0039] Also in the warp knitted lace fabric 1, similarly to the above-described embodiment, the back cloth 20 having the wide region portion 11 and the narrow region portion 12 and one unit corresponding to the cup portion. The length is repeated and knitted into a long length, and after knitting, it is cut into 1 unit length. As shown in FIG. 7, a pad or the like is attached to the inside of the portion 15 corresponding to the cup portion 25 in the wide region portion 11 for use.
