Description

  The present invention relates to a narrow woven fabric that has an elastic restoring force and can be used as a shape-retaining material for clothing.

  In order to maintain the neat shape of the garment, it has been practiced to attach a shape retaining material called a wire in the industry terminology to a specific part of the undergarment, such as the underbust of the brassiere. This shape-retaining material is an elongated molded product made of metal or plastic that is bent into a predetermined shape such as a semicircular shape. A band-shaped shape retaining material may be attached to the girdle body. This type of shape retainer is usually attached by sewing an annular fabric at the desired location on the garment and inserting the shape retainer therein.

  However, metal and plastic wire rods are very hard compared to fabrics, so they are unsuitable for attachment, or if the annular fabric into which they are inserted does not have sufficient cushioning properties, it gives a sense of incongruity during clothing. There's a problem. In addition, the ring fabric deteriorates during repeated washing, and the tip of the shape retaining material breaks out of the ring fabric and jumps out, or the ring fabric loses cushioning properties and impairs comfort.

  These problems are sought to be solved by using an annular woven fabric in which the weaving point of the annular woven fabric is not widened by densifying the woven fabric of the annular woven fabric or by welding the interweaving points using a heat-fusible thread. Proposals have been made.

  The above-mentioned problems when attaching a shape retainer to underwear are very different in hardness, tactile sensation and flexibility between the metal or plastic that is the shape retainer and the fabric of the underwear to which this shape is attached. There is a fundamental problem in attaching a hard linear or belt-shaped shape retaining material to an underwear fabric that is very flexible and excellent in tactile sensation.

  Therefore, the present invention is intended to fundamentally solve the above-mentioned conventional problems by providing a narrow woven fabric having shape retention, and the woven fabric itself has an elastic restoring force against bending in the longitudinal direction. It is an object of the present invention to provide a narrow woven fabric capable of imparting shape-retaining properties due to its elastic restoring force by sewing to a desired portion of clothing.

  The narrow fabric according to the present invention is formed by connecting two layers of woven structures 10 and 20 including the elastic yarns 1, 11 and 12 of the weft and the back side, and connecting the warp yarns 7 and 8. A structure in which a large number of insertion warps 9 that are not interwoven with wefts are filled between the front and back woven structures 10, 20 defined by the connecting portions 7a, 8a of the connecting warps that pass between the layers. Has elastic restoring force in the direction.

  A narrow woven fabric of the present invention is a two-layer woven structure 10 of a narrow surface layer and a lower layer woven by warp groups 1 and 2 including elastic yarn 1 and weft groups 11 and 12 including elastic yarns 11 and 12. 20 are arranged between the warp yarns 1 and 2 forming the front and back woven structures, and the connecting warp yarns 7 and 8 for connecting the front and back layers are arranged. The connecting warps 7 and 8 are portions 7a and 8a that cross the front and back layers 10 and 20, and divide the space between the front and back woven structures into a plurality of regions in the width direction. An insertion warp 9 is inserted into each of the divided areas without interweaving with the wefts 11 and 12. The insertion warp 9 is filled in each of the regions so that the elastic yarns 1, 11, 12 with the wefts 10, 20 on the front and back sides are stretched.

  A preferred narrow woven fabric of the present invention is a pair of warp yarns that connect two warp yarns 7 and 8 adjacent to each other to connect a space between the front and back woven structures 10 and 20 formed by the union warp yarns 1 and 2. 7 and 8 are arranged between two adjacent warp pairs, and two union warp yarns 1 and 2 forming the front and back weave structures 10 and 20 are arranged, and the number of union warp yarns is larger than the number of union warp yarns. The insertion warp 9 is arranged.

  The narrow woven fabric of the present invention can be provided with a seam allowance portion B for sewing the main body portion (the portion having an elastic restoring force in the bending direction) A of the above structure to the fabric. That is, a single layer of woven structure B serving as a seam allowance is formed on both sides in the width direction of the main body A provided with the two layers of woven structures 10 and 20. The material of the elastic yarn 3 and the non-elastic yarns 4, 5 and 6 used for the portion B, and these and the weft yarn so that this single layer of woven structure B is provided with the same longitudinal elasticity as that of the main portion A. 11 and 12 are determined.

  The narrow woven fabric configured as described above has several warp yarns (2 in the following examples) including elastic yarns 1 that interweave with weft yarns including elastic yarns (weft yarns 11 and 12 in the following examples are all elastic yarns). Two layers of thin union texture formed by union with two union warp yarns 1, 2), that is, formed by several union warp yarns 1, 2 arranged between adjacent tether warp pairs 7, 8. A state in which a larger number of inserted warps 9 than the number of warps forming the narrow unwoven structure are packed in the space between the two layers of narrow unwoven structures without being interwoven with the wefts 11 and 12 It has become.

  During weaving, the warp and the weft are interwoven with a predetermined tension applied, so the elastic yarn 1 of the warp is in a stretched state. Therefore, in the narrow woven fabric of the present invention, two layers of woven structures 10 and 20 are formed which are two-dimensionally tensioned by the longitudinal and horizontal elastic yarns 1, 11 and 12. Since the insertion warps 9 are packed in the space and the number of the insertion warps 9 is larger than the number of the union warps 1, 2, the two layers of union structures 10, 20 are separated by the insert warp group. It is in the state.

  As a result, in the narrow woven fabric of the present invention, when bending deformation in the warp direction and the weft direction occurs, the elastic yarn of the woven structure that is the outside of the bend is greatly stretched, and the elastic yarn of the woven structure that is the inside of the bend The tension is relaxed. Therefore, when the external force is released, the tension returns to the restored state in which the tensions of the two elastic yarns are equalized by the tension of the elastic yarns outside the bend. By this effect | action, the narrow fabric of this invention is equipped with an elastic restoring force, and the effect | action as a shape-retaining material is exhibited.

  The tension applied to the warp during weaving can be changed according to the position in the width direction of the fabric through which the warp is inserted. If the tension applied to the warp is gradually changed from one side in the width direction of the narrow woven fabric to the other side, the woven narrow fabric can be bent in the longitudinal direction in a restored state. For example, a shape-retaining material used for an underbust of a brassiere can be obtained by giving a long circular arc-shaped bend to a narrow woven fabric and cutting it into an appropriate length.

  The narrow woven fabric of the present invention is itself a woven fabric, using a covering yarn as an elastic yarn, or appropriately selecting and using a kind (material) of a woven warp or a joining warp as an inelastic yarn, A touch or texture close to that of the fabric forming the underwear can be imparted. In addition, by adjusting the tension applied to the warp and weft during weaving, and by appropriately selecting the type of union warp and tie warp and the form of union with the weft, the elastic restoring force imparted to the narrow woven fabric can be obtained. Can be adjusted.

  The elastic restoring force and hardness (hardness) imparted to the narrow woven fabric of the present invention is much closer to the cloth of clothing than metal and plastic, so the narrow woven fabric of the present invention is attached when worn. There is no sense of incongruity in the part. In addition, when washing is repeated, the narrow woven fabric of the present invention deteriorates to the same extent as the deterioration of the fabric forming the underwear, so the comfort does not change greatly.

  The narrow woven fabric of the present invention is a flat (single layer) seam allowance portion for sewing the narrow woven fabric of the present invention to a fabric such as underwear by providing a woven region where the insertion warp 9 is not inserted on both sides in the width direction. B can be formed. This seam allowance part B is given a stretchability equivalent to that of the main part A having two layers by making it a woven structure different from that of the two layers and by making the type of warp different. can do. In order not to cause wrinkles in the sewn portion when the fabric is sewn, it is important to give this seam allowance B the same elasticity as that of the main body A.

  For example, a metal or plastic shape-retaining material disclosed in Patent Document 1 can be obtained by heat-bonding the entanglement points between elastic yarns by performing heat treatment after weaving using an elastic yarn provided with heat fusion as an elastic yarn. It is known as an annular woven fabric for inserting the. Also in the narrow woven fabric of the present invention, a weaving structure in which the weaves do not spread can be obtained by using elastic yarns having heat-fusibility to the warp elastic yarns.

Side view showing union state of union warp and weft Side view showing the interweaving state of the joining warp and weft Side view showing the relationship between inserted warp and weft Side view showing the interweaving state of elastic yarn and weft at the seam portion Side view showing the interweaving state of the inelastic first yarn and weft of the seam allowance Side view showing the interweaving state of the inelastic second thread and weft of the seam allowance

  Next, the narrow fabric according to the present invention will be described with reference to the embodiments shown in the drawings. The narrow woven fabric in the illustrated embodiment is woven by a two-needle loom. Reference numerals 1 and 2 and 7 to 9 are warps of the main body A, reference numerals 1 and 2 are union warps, 7 and 8 are connecting warps, and 9 is an insertion warp. Reference numerals 3 to 6 are warps of the seam allowance B. Reference numerals 11 and 12 are wefts. The union warp indicated by reference numeral 1 and the warp and weft threads 11 and 12 of the seam portion indicated by reference numeral 3 are covering yarns having an elastic yarn, specifically, polyurethane as a core yarn. Inelastic yarns such as the joining warps 7 and 8 and the insertion warp 9 are wooly nylon.

  As shown in FIG. 4, the interwoven weft 1 of elastic yarn and the interwoven weft 2 of inelastic yarn are interwoven with plain weave fabrics 10 and 20 respectively with an upper weft 11 and a lower weft 12. As shown in FIG. 5, the joining warps 7 and 8 are interwoven with one of the lower wefts 12 for every three upper wefts 11. The joining warps 7 and 8 are interwoven with the lower wefts 12 alternately. Both are inelastic yarns. The pair of connecting warps 7 and 8 are alternately arranged with two union warps 1 and 2 in a pair, that is, upper and lower layers.

  The connecting warps 7 and 8 are divided in the width direction into spaces formed by the upper and lower layers of the interwoven structures 10 and 20 in the portions 7a and 8a extending between the upper weft 11 and the lower weft 12 shown in FIG. It has become a thread. That is, in the narrow woven fabric of this embodiment, a thin (narrow) woven fabric formed by two woven warp yarns 1 and 2 is formed between adjacent pairs of connecting warp yarns 7 and 8. . The union warp yarns 1 and 2 between the adjacent pair of warp yarns 7 and 8 are four when the upper and lower layers are combined.

  As shown in FIG. 6, a large number of yarns that are not interwoven with the wefts 11 and 12 (in the example shown in the figure, 10) in the region partitioned by the adjacent connecting warp pairs 7 and 8 in the space between the upper and lower woven fabrics 10 and 20. The insertion warp 9) is inserted. As described above, the insertion warp 9 functions as a filler filled between the upper layer and the lower layer woven structure, so that the distribution state does not collapse by moving in the width direction of the narrow woven fabric. In addition, in order to maintain the distance between the upper and lower woven fabrics 10 and 20 at a predetermined distance, the joining warp pairs 7 and 8 are used.

  Further, since the joining warps 7 and 8 are interwoven so as to appear long on the outer side (surface side) of the upper weft 11, the appearance and tactile sensation of the surface of the narrow woven fabric (upper side in the figure) are determined. It plays a big role, and the appearance and texture of the surface vary greatly depending on the type of yarns of the joining warps 7 and 8.

  The portions B on both sides of the main body A are portions that become seams. The texture of this part is shown in FIGS. The woven structure of this part and the use of the warp are not related to the elastic restoring force in the narrow woven fabric of the present invention, but the elastic yarn is provided so as to have the same stretchability as that of the main body A where the insertion yarn 9 is arranged. 3 and the number of inelastic yarns 4, 5, 6 and the woven structure need to be determined. Therefore, the woven structure of this part varies greatly depending on the expansion / contraction ratio of the elastic yarn used and the type of inelastic yarn, and even if the number of elastic yarns and the type of inelastic yarn are the same, various woven structures can be used. It is.

  In the above embodiment, two union warp yarns 1, 2 are arranged between adjacent upper and lower warp pairs 7, 8, but the number of union warp yarns between adjacent union warp yarns is, for example, three. The number can be four, or in some cases five. Also in this case, the number of the inserted warp yarns 9 is larger than the number of the union warp yarns 1 and 2. In the above embodiment, ten insertion warps 9 are inserted into the two upper and lower union warp yarns 1 and 2 respectively. It is appropriate to increase the number of insertion warps 9 at approximately the same ratio as this. However, since the insertion warp 9 is basically the size of the cross-sectional area, if a thick insertion warp is used, the number of insertion warps 9 is increased accordingly. It is possible to reduce it.

  The narrow woven fabric of the present invention obtained as described above is used, for example, by being sewn to the underbust of a brassiere at the portion of the seam allowance B on both sides. The narrow woven fabric of this invention has a shape-retaining property, so it works to adjust the shape of the bust, and since the whole is made of fibers, it has good affinity with clothing and may feel hard on the skin. It is possible to give the brassiere excellent comfort and formability.
