Description

  The present invention is an improvement of a narrow band for decoration, more specifically, it is possible to form a concavo-convex pattern with excellent design and a hologram-like appearance on the surface of a fabric by a simple process, and the side edge portion The present invention relates to a concavo-convex decorative narrow strip that is easy to use without curling, and a method for manufacturing the same.

  As is well known, there is a decorative narrow band for decorating clothes, and it can be given a one-point accent by arranging it on the side line of the clothes (for example, see Patent Document 1). .

  However, such a conventional narrow band body has a flat shape, is not interesting in design, and is unsatisfactory in decoration.

  However, even if unevenness is formed on the fabric surface to give a three-dimensional visual effect, if a decorative base material such as beads or sequins is sewn, the manufacturing process becomes complicated and the manufacturing cost increases. There's a problem. In addition, there is a method of forming irregularities by inserting a core yarn along the warp direction of the fabric, but there is a problem that the fabric becomes heavy by that amount.

  Furthermore, some heat shrink yarns are used to form irregularities on the surface of the fabric using the difference in shrinkage, but heat treatment is performed in a state where the heat shrink yarn and the non-heat shrink yarn are knitted and woven. When this is done, the non-shrinkable fiber yarn is pulled and warped at the ear portion at the side edge of the fabric, and this portion has a problem that the appearance of the portion is deteriorated and it is difficult to attach to the clothes.

  The mode for carrying out the present invention will be described in more detail with reference to the drawings specifically illustrated as follows.

“First Embodiment”
A first embodiment of the present invention will be described with reference to FIGS. In FIG. 1, what is indicated by reference numeral 1 is an upper ground 1, and the upper ground 1 is made of a woven fabric and is formed by warp direction yarns 11 and weft direction yarns 12. Also, what is indicated by reference numeral 2 is a base 2, which is made of a woven fabric structure and is formed by a base warp direction yarn 21 and a weft direction contraction yarn 22.

  In the present embodiment, a single tissue portion consisting only of the upper ground 1 is located at both ends (C) in the width direction of the narrow band body, and the upper ground 1 and the base 2 are separated from each other on the inner side. The bag tissue portions (A) and the single tissue portions (B) in which the upper base 1 and the base 2 are integrated are alternately arranged. Here, the “single tissue portion” means a single fabric or a state in which the fabric is a single piece by joining the fabrics, and the “double tissue bag portion” means that the upper fabric 1 and the lower fabric 2 are not. A bag-like gap is formed between the doughs independently of the joining.

  The single tissue portion (C) of both ends (C) of the present embodiment is composed of the warp direction yarn 11 and the weft direction yarn 12 of the upper fabric 1, while the single tissue portion (B) located inside the belt body is The warp direction yarns 11 / the base warp direction yarns 21 and the weft direction yarns 12 / the weft direction contraction yarns 22 constituting the upper ground 1 and the base 2 are crossed with each other. At this time, part of the warp yarn or weft yarn of the upper fabric 1 or the lower fabric 2 is used as a connecting yarn and is partially connected, so that it does not cross at a high density, which is preferable because it does not form a hard fabric texture.

  Further, the warp direction yarn 11 and the weft direction yarn 12 of the upper fabric 1 and the warp direction yarn 21 of the base 2 are made of non-shrinkable fiber yarns, and the warp direction shrinkable yarn 22 of the base 2 is made of heat-shrinkable fiber yarns. It has become. The weft-direction yarn 12 constituting the upper fabric 1 is folded back over the entire width of the narrow strip, while the heat-shrinkable weft-direction shrink yarn 22 is an inner side excluding both ends (C) of the narrow strip 1. It is folded in the department.

  The warp direction yarns 11 and the weft direction yarns 12 of the upper fabric 1 and the non-shrinkable fiber yarns of the base warp direction yarn 21 of the base 2 are fiber yarns usually used for clothing, including synthetic fibers and semi-finished fibers. Synthetic fibers or natural fibers such as cotton, wool, silk, blended yarns or twisted yarns thereof can be used, and further, a spandex elastic fiber is used for the warp direction yarn 11 for the purpose of obtaining stretch recovery. You can also.

  On the other hand, as the heat-shrinkable fiber yarn used for the weft-direction shrink yarn 22 of the base 2, a thermoplastic resin fiber such as a polyester fiber, an acrylic fiber, or a vinyl chloride fiber can be employed. Those that shrink by low temperature heat treatment are preferred. In the present embodiment, the weft direction shrink yarn 22 of the base 2 is a polyester fiber yarn having a hot water shrinkage of 20 to 60%.

  The hot water shrinkage is a value measured according to JIS L1013 skein shrinkage (Method A, treatment temperature 98 ± 2 ° C.), and when the hot water shrinkage of the weft direction shrink yarn 22 is 20% or less, The ridges 13 do not rise sufficiently and the expected design effect cannot be obtained. Moreover, when the hot water shrinkage rate is 60% or more, it is preferable for raising the ridges 13, but there is a problem that it becomes difficult to finish to the standard width because the width of the narrow strip 1 is greatly shrunk, It is preferable that the hot water shrinkage rate of the weft direction shrink yarn 22 is 20 to 60%.

  By heat-treating the narrow band woven in the above-described configuration, the weft-direction shrink yarn 22 of the base 2 which is a heat-shrinkable fiber yarn is thermally contracted, and the double bag tissue portion (A) and the single tissue portion ( B) shrinks in the width direction, and the upper ground 1 of the double bag tissue part (A) rises, and the ridges 13, 13,... Can be formed along the length direction of the narrow band ( 2 and 3).

  At this time, since there is no heat-shrinkable weft in the single tissue part at both ends (C) of the narrow band, the contraction force does not act even if heat treatment is performed, so the end part is curled. Therefore, the appearance as a product is not deteriorated, and it is not necessary to perform a sewing process while extending the curled state even in the work of attaching to clothes.

  In the present embodiment, the double bag tissue part (A) and the single tissue part (B) may be fixed and continuously provided along the length direction of the narrow band, By changing the arrangement of the double bag tissue part (A) and the single tissue part (B) at intervals, the discontinuous ridges 13 that are intermittent in the length direction can be formed. Any pattern can be easily created (see FIG. 4).

  In addition, as shown in FIG. 5, by providing a pattern pattern in which the color of the ridge 13 is dark and the color of the groove 14 formed between the ridges 13 and 13 is light or light, A pale pattern is observed as if it floats from between the ridges 13, and a three-dimensional appearance like a hologram can be exhibited.

  For example, if the ridge 13 of the belt is black or amber, and the groove 14 is connected to the adjacent groove 14 in the color of the same color as the ridge 13, such as fluorescent white, At the same time that the handle is observed to emerge from between the ridges 13, the effect of making the handle appear to move is exhibited by changing the viewing angle.

  Furthermore, by arranging warp yarns of different colors on the left and right surfaces forming the ridges 13, a visual effect that different colors enter the eyes depending on the viewing angle is obtained, and an excellent design effect is exhibited. be able to.

  The width of the narrow band according to the present embodiment is appropriately selected depending on the application, but is about 10 to 50 mm for use as a decorative band such as clothes, and the pitch of the ridges 13, 13,. Is preferably about 1 to 3 mm. Although the hologram effect is more easily obtained when the pitch is narrower, the color pattern of the groove 14 becomes inconspicuous when the pitch is 1 mm or less, and is preferably 1 mm or more.

  Further, the height of the ridge 13 is preferably about 0.4 to 2 mm. When the thickness is 0.4 mm or less, the unevenness is insufficient. On the other hand, when the thickness is 2 mm or more, the form becomes unstable, and the ridges 13 are not linear, and the appearance is not good.

  Furthermore, it is desirable that the shape of the ridge 13 is maintained even when worn for a long period of time. For this purpose, the structure constituting the ridge 13 is a flat structure having a high restraining force between the warp direction yarn and the weft direction yarn. It is preferable that the warp direction yarn 11 and the weft direction yarn 12 are woven with a fineness and a high density to make a hard woven fabric.

  Specifically, the fineness of the warp direction yarn 11 and the weft direction yarn 12 is 50 to 160 dtex, the weave density of the warp direction yarn 11 is 30 to 70 / cm, and the weave density of the weft direction yarn 12 is 15 to It is preferably woven at 40 pieces / cm.

Further, in the weaving conditions of the woven portion constituting the ridge 13, the warp direction yarn 11 has a fineness Tw (dtex), the weave density Dw (lines / cm), the weft direction yarn 12 has a fineness Tf (dtex), When the weaving density is Df (lines / cm), the relationship of the following formula is preferable.
√ (Tw × Dw) = k (√ (Tf × Df))
K = 1.2 to 2.0

  By using the relationship of the above formula, the warp direction rigidity of the fabric portion constituting the ridge 13 is larger than the rigidity in the weft direction, so that the weft direction thread 12 is easy to bend and at the same time warp direction thread. Since 11 is linearized, the convex shape 13 extends linearly in a state where the weft direction thread 12 is bent at an acute angle, so that the design is further increased.

  In addition, if k is 1.2 or less, the weft-direction yarn 12 becomes difficult to bend because the rigidity in the warp direction of the woven fabric portion constituting the ridge 13 is insufficient and the weft-direction yarn 12 is difficult to bend. Thus, the expected design effect cannot be obtained.

  On the other hand, when k is 2.0 or more, the rigidity in the weft direction is reduced, the shape retaining property of the ridges 13 is lowered, and the ridges are crushed during repeated wearing, and the target design effect is lost. And the range of k is preferably 1.2 to 2.0.

  Furthermore, in order to make the ridges 13 rise as upright as possible, the shrinkage rate of the base 2 of the double bag tissue part (A) may be increased, and a fiber yarn having a high heat shrinkage rate may be used. Use a twill structure or satin structure where the weft yarn has a small binding force.

  On the other hand, the single tissue portion (B) that becomes the concave groove portion 14 is shrunk due to the presence of the heat-shrinkable fiber yarn of the weft direction yarn, but the number of warp direction yarns may be determined to have a predetermined width.

  Further, the concave groove portion 14 is formed by connecting the warp direction yarn 11 for the upper fabric and the base warp direction yarn 21 for the ground fabric to form a handle while forming a pattern to form a single tissue portion (B). As a method of expressing the pattern, the weft direction thread is concealed by forming the pattern with a long warp float structure, and the warp direction thread of the base 2 is set against the warp direction thread 11 of the top 1 21 makes it possible to draw clear patterns.

  The concavo-convex decorative thin strip having the woven structure according to the present embodiment can be woven using a shuttle loom having at least two cloves, a needle loom, or the like. In particular, a needle loom can be woven while the warp yarn openings are divided into two stages and the non-shrinkable fiber yarn of the upper fabric 1 and the heat-shrinkable fiber yarn of the lower fabric 2 are simultaneously inserted into the weft to obtain high productivity. be able to.

  The specific manufacturing process is as follows. First, the warp yarn is prepared for the upper side and the lower side, and both end portions (C) in the width direction, the double bag tissue portion (A), and the single tissue portion (B) are formed. Weft weave and repeat weft insertion to weave. At this time, both ends (C) use either warp yarns for the upper or base, and in the single tissue portion (B), some warp yarns for the upper and the base warp are used. The yarn is replaced and opened to be integrated as a single tissue part.

  At this time, if the colors of the warp direction yarns for the upper side and the lower side are different from each other and are changed so as to draw a pattern on the concave groove portion 14, the design can be integrated and more effective.

  The weft direction yarn 12 made of non-shrinkable fiber yarn is inserted into the weft yarn while being folded over the entire width, while the weft direction shrink yarn 22 made of heat-shrinkable fiber yarn has both ends (C) removed. Insert it while folding it inside. By doing so, the weft direction yarn of the heat-shrinkable fiber yarn is not inserted at both ends (C), so the shrinkage force does not act on the side surface of the base 2 even after heat treatment, and curling of the end is prevented. can do.

  Next, the woven narrow strip is heat-treated to shrink the heat-shrinkable fiber yarn (weft-direction shrink yarn 22) inserted in the weft yarn on the base 2 side, and the upper fabric 1 of the double woven bag tissue part (A). The ridge 13 is formed by raising. As a method of heat shrinkage treatment, either dry heat or wet heat method is possible, and it is preferable to shrink at a high temperature as much as possible so that there is no delayed shrinkage. The treatment temperature is preferably 100 ° C. or higher. Further, weaving can be performed on the premise of post-dyeing, and heat shrinkage can be performed at the dyeing temperature at the time of post-dyeing.

  The decorative band of the present invention can be used as a decorative tape by being arranged on clothes such as sportswear, and the uneven pattern of the decorative tape exhibits a three-dimensional appearance according to the movement of the body, and if necessary By making the differently colored yarns that can be arranged in the concave groove portions 14 appear and disappear depending on the viewing angle, it is possible to obtain a highly fashionable garment rich in change.
