Description

  The present invention relates to a narrow woven fabric in which two types of weft (weft) are woven into warp (warp), and a method for weaving the same.

  Some narrow woven fabrics such as tatami margins, as seen in Patent Document 1, for example, have two types of wefts woven into warp yarns, and each weft yarn appears intermittently to form a surface having a change in hue. . Here, “two kinds of wefts” mean wefts having different colors, but the material type, the number of filaments, and the thickness (denier or tex) may be different. The narrow woven fabric of Patent Document 1 is woven by weaving a normal weft and a flat decorative yarn with a bright color such as gold and silver into a warp. Further, as seen in Patent Document 2, there are also two monofilament yarns having at least one different color from warp yarns, and narrow fabrics in which monofilament yarns and multifilament yarns are woven into warp yarns.

  A narrow woven fabric in which two types of wefts are woven into warp yarns is woven by, for example, a narrow weaving machine found in Patent Document 3. In the narrow loom of Patent Document 3, two types of weft yarns (a, b) are alternately locked to the forward and backward needles (14) and woven into the warp yarns (c). Patent Document 3 relates to a technique for preventing each weft from being skewed with respect to the warp, and means for locking two kinds of wefts (a, b) alternately to the needle (14) is described in detail. However, it is assumed that the needles (14) reciprocating on the same track are alternately locked by reversing the positional relationship of the weft threads (a, b). The current mainstream is a weaving method in which two types of weft yarns are collectively inserted into a needle guide hole, and the needles are reciprocated between warp yarns to weave the weft yarns into the warp yarns.

  As described in Patent Document 1 and Patent Document 2, a narrow woven fabric in which two types of wefts are woven into warp yarns forms a surface in which the color changes when the two types of weft yarns appear intermittently. However, in the weaving method in which two types of weft yarns are collectively inserted into the guide hole of the needle and the needle is reciprocated between the warp yarns to weave the weft yarns into the warp yarns, the appearance of each weft yarn tends to be monotonous. There is a problem that the appearance of the color is uneven and the change in hue becomes uneven. In particular, when wefts with a light color tone such as pastel colors are used, it is easy to emphasize that the change in shade is uneven, and regular change in shade is recognized as uneven weaving, reducing the commercial value of narrow fabrics. End up. From this, it is desired that the narrow woven fabric in which two types of wefts are woven into warp yarns, the appearance of each weft yarn is made irregular and uniform, and the change in surface color is made uniform.

  When the two types of wefts are woven into the warp yarns, the change in surface color is non-uniform because the two types of wefts inserted through the needle guide holes are always woven in a fixed positional relationship. In this regard, as seen in the narrow weaving machine of Patent Document 3, if the two types of weft yarns are independently woven into the warp yarns, the positional relationship between the two types of weft yarns is considered to change relatively. It is easy to weave a narrow woven fabric that makes the change in color shade uneven. However, it is difficult to alternately engage the two types of wefts with the needles, and it is inevitable that the needles cannot engage the wefts, and the productivity of narrow fabrics cannot be increased. Therefore, when weaving a narrow woven fabric that weaves two types of weft yarns into warp yarns, while changing the positional relationship of the two types of yarns and weaving them into the warp yarns while improving productivity, the change in surface color is uniform. We studied to develop a weaving method.

Was developed result of the examination is, in narrow fabric is woven incorporate two types of weft in the warp, hand weft is woven in the warp while positional change a supply path in the warp narrow fabrics is there. Here, “change the position of the supply path leading to the warp” means that there are at least two or more weft supply paths from the supply means to the warp and the weft is woven into the warp. In this case, it means that each supply path is switched or continuously changed. In this case, since the plurality of supply paths are common at the start ends with the weft supply means and are not in the same position as the warp yarns where the end ends are woven, there is no change in position in the middle from the start end to the end. It is switched in the mode to do. Further, “fixing the position of the supply path leading to the warp” described later means that the position of the path does not change.

Narrow fabrics of the present invention, when weaving two weft in the warp, by positional change of the supply path of hand weft, to change the weft relative positional relationship interworking in the warp, wherein each respective weft The appearance of the surface of the surface of the surface of the surface is irregularly and evenly to avoid unevenness of the surface color. The appearance of the surface of the weft varies depending on how much the positional relationship between the wefts changes, and the uniformity of the surface color also changes depending on the appearance of the surface of the weft. For example, in order to make the color of the surface uniform to the extent that it is not evaluated as uneven weaving, the positional relationship of the wefts to be woven into the warp need not be regular, so it is only necessary to relatively change the position of the supply path of the two types of wefts. .

To uniform change in color of the surface, one of the weft, the feed path in the warp and fixed weaving the warp, weft other, supplying one of the weft located fixed supply path do narrow path It is good to weave in the warp while changing the position. As described above, since the supply paths of the two types of wefts only need to change their positions relatively, it is easiest to change the position of the other supply path of the wefts with reference to one supply path of the wefts. Also, one of the weft located fixing the supply path in I clamping, by positional change of the weft thread in the other supply path, switches the positional relationship of the weft thread when woven into the warp, appear side in the weft of the surface Can be made uniform evenly, and the change of the surface color can be made uniform .

More preferably, one of the wefts fixes the supply path leading to the warp and weaves it into the warp, and the other of the wefts turns into a warp while changing the position of the supply path by sandwiching one of the wefts with the supply path fixed in the vertical direction. It is good to weave. When two types of weft are combined and woven into the warp, the weft is in a generally vertical positional relationship. As a result, the positional relationship of the weft yarn when it is woven into the warp yarn is changed up and down by changing the position of the other supply route of the weft yarn by sandwiching one of the weft yarns up and down with respect to one of the weft yarns whose position is fixed. It is possible to change the direction of the surface and make the appearance of the surface of the weft yarn irregular and even, and the change in the color of the surface can be made uniform .

Since the current narrow weaving machine uses a needle to weave the weft yarn into the warp yarn, the method for weaving the narrow fabric according to the present invention is as follows. That is, when two kinds of wefts are supplied from the supply means, and the weft yarns are woven into the warp yarns by reciprocating between the warp yarns by combining the weft yarns and inserted into the guide holes, the narrow woven fabric is woven. , hand of weft, is interposed supply path displacement means between reaching the guide bore of the needle from the supply means, narrow weaving the warp while the supply path is positioned changed leading to induction hole of the needle by the supply path displacement means This is a method of weaving a fabric.

  The supply means and the needle may be the same as the supply means and needle in the conventionally known narrow loom, but the needle guide hole preferably has an opening surface parallel to the direction in which the position of the supply path of the weft yarn is changed. The supply path displacing means has a part for engaging or inserting the weft thread that is supplied to the guide hole of the needle, and changes the position of the supply path for the weft thread by changing the position of the engaging or inserting part. If there is enough. Here, since the position change of the part to be engaged or inserted may be a simple repetitive movement, the supply path displacing means, for example, provides an interlocking arm at the repetitive movement part of the narrow loom, and engages the weft with the interlocking arm. Or it can comprise by providing the site | part made to penetrate.

In the narrow loom that weaves the weft yarn into the warp yarn using the needle, when the needle enters between the warp yarns, the weft yarn is bent from the supply path toward the warp yarn. As a starting point for bending the supply path by the needle, a holding guide for winding the weft is used. Now, weaving methods narrow fabrics of the present invention, hand weft is inserted through the guide bore of the needle by turning over the holding guide from the supply means, the supply path displacement between reaching the holding guide from said supply means This is a weaving method in which weaving means is woven into the warp while changing the position of the supply path connecting the holding guide and the guide hole of the needle by the supply path displacement means. Here, as described above, the holding guide only needs to be a starting point for bending the supply path by the needle. From the closed frame that forms the weft insertion hole and the rod that is addressed to the inside of the bending weft. The open frame body comprised can be illustrated.

Also in the weaving method of the present invention, as described above, it is preferable to fix the position of one supply path of the weft and to change the position of the other supply path of the weft. That is, the supply path displacement means, one of the weft threads not interposed the supply path displacement means may be located change the weft of the other supply path do today. More specifically, the supply path displacing means may change the position of the other supply path of the weft with one of the wefts not interposing the supply path displacing means being vertically sandwiched . In this case, the supply path displacing means can be configured by providing an interlocking arm at a part that repeatedly moves in the vertical direction of the narrow loom, and providing a part for engaging or inserting a weft thread into the interlocking arm.

The narrow woven fabric of the present invention is not evaluated as uneven weaving by making the change in surface color uniform, but rather can increase the commercial value as a surface that is adjusted to a uniform color overall. In particular, when a weft having a light color tone such as pastel color is used, the entire surface is adjusted to a light color, and for example, the commercial value of a tatami mat using the weft can be increased. This is the effect due to the woven in the warp while positional change a supply path to the hand of the warp weft. The effect is a supply path to one warp weft fixed position, the supply path weft of the other, while one of the supply path is positioned changed I clamping the weft thread located fixed, preferably weft other This is better achieved by weaving each warp while changing the position of the supply path while sandwiching one of the wefts with the supply path fixed in position.

Weaving method of the present invention, upon weaving weft warp using a needle, by varying the weft supply path with intervening supply path displacement means the feed path of the hand of the weft, the tint of a surface A narrow woven fabric of the present invention in which the change is uniform can be woven. At this time, in the present invention, the weft thread is inserted into the guide hole of the needle and is woven into the warp thread. Therefore, as in Patent Document 3, there is no problem that the needle cannot lock the weft thread. Easy to increase productivity. Further, the supply path displacing means can be configured, for example, by providing a part for engaging or inserting a weft thread into the interlocking arm at a part where the narrow loom repeatedly moves. In addition, the narrow fabric of the present invention can be easily woven.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial perspective view showing a narrow fabric 1 according to the present invention, and FIGS. 2 to 7 are weft yarns 11 (hereinafter referred to as displacement weft yarns 12) for changing the position of the supply path and fixed positions of the supply path. FIG. 2 is a partial plan view, a partial front view, or a partial side view of the narrow loom showing a state where the supply path is positioned above the fixed weft thread 11), and FIG. 2 is a view before weft threads 11 and 12 are woven between the warp threads 13; FIG. 3 is a partial front view of the stage before weaving the weft threads 11 and 12 between the warp threads 13, and FIG. 4 is a partial side view of the stage before weft threads 11 and 12 are weaved between the warp threads 13. 5 is a partial plan view of a stage in the middle of weaving the weft threads 11 and 12 between the warp threads 13, FIG. 6 is a partial plan view of the stage after weaving the weft threads 11 and 12 between the warp threads 13, and FIG. 11 and 12 show partial side views of the stage where weaving is finished between the warp yarns 13, and FIGS. 8 to 13 show the displacement weft yarn 12 positioned below the fixed weft yarn 11 in the supply path. FIG. 8 is a partial plan view, a partial front view, or a partial side view of a narrow loom showing a state in which the weft is shown, FIG. 8 is a partial plan view of a stage before wefts 11 and 12 are woven between warp yarns 13, and FIG. , 12 is a partial front view of the stage before weaving between the warp threads 13, FIG. 10 is a partial side view of the stage before weaving the weft threads 11 and 12 between the warp threads 13, and FIG. FIG. 12 is a partial plan view of a stage in the middle of weaving, FIG. 12 is a partial plan view of a stage in which wefts 11 and 12 have been woven between warp threads 13, and FIG. FIG.

  In the narrow woven fabric 1 according to the present invention, as shown in FIG. 1, the fixed weft yarn 11 and the displacement weft yarn 12 appear evenly on the surface, and the change in the color of the surface is made uniform. This means that the color of the fixed weft 11 and the color of the displacement weft 12 are mixed evenly. From this, for example, when both the fixed weft 11 and the displacement weft 12 have a light color tone such as a pastel color, both appear irregularly and evenly on the surface, so that the entire surface is arranged in a light shade and very appearance An excellent narrow fabric 1 can be obtained. There is a tatami mat as a product in which color is important as the narrow fabric 1, and the present invention exhibits an effect of increasing the commercial value of the tatami mat.

  The narrow woven fabric 1 of this example is woven by a weaving procedure similar to the conventional one, for example, by adding a displacement guide (supply path displacing means) 2 for switching the supply path of the displacement weft yarn 12 to a ready-made narrow loom. The main part of the narrow loom of this example will be described. As shown in FIGS. 2 to 4, the basic portion of the narrow loom of this example is the same as the conventional narrow loom. The fixed weft yarn 11 and the displacement weft yarn 12 are individually supplied from the respective supply means (not shown), are wound around the holding guides 32 and 33, and are inserted through the guide hole 311 of the needle 31 together. Then, the needle 31 reciprocates between the warp yarns 13 to feed the fixed weft yarn 11 and the displacement weft yarn 12 between the warp yarns 13 and strikes and weaves with the heel 3. Further, when the fixed weft yarn 11 and the displacement weft yarn 12 are fed between the warp yarns 13, a holding needle (Bella needle) 35 for temporarily holding the weft yarns 11 and 12 is provided in the same manner as in the prior art.

  The weaving method of the present invention is characterized in that the displacement guide 2 (supply path displacement means) is interposed between the supply means of the displacement weft 12 and the holding guide 33. As a result, the supply path of the fixed weft 11 does not change, but the supply path of the displacement weft 12 follows the displacement guide 2 that is displaced in the vertical direction within the range connecting the holding guide 33 and the guide hole 311 of the needle 31. The position changes up and down across 11. The holding guide 32 of the fixed weft 11 is on the left side when viewed from the front, and is in the shape of a ring arranged at a height corresponding to the turning surface of the needle 31, but the holding guide 32 of the displacement weft 12 is viewed from the front. It is on the right side and has a long hole shape extending vertically with the swivel surface of the needle 31 interposed therebetween. Further, in order for the supply path of the displacement weft 12 to smoothly change its position, the guide hole 311 of the needle 31 has an opening surface parallel to the vertical direction (vertical direction) in which the supply path of the displacement weft 12 changes its position.

  The displacement guide 2 forms an inclined engagement portion 21 that is inclined obliquely forward from the upper end of the attachment portion provided with an attachment loop at the lower end, and is further turned from the lower end of the inclined engagement portion 21 toward the attachment portion. Thus, the mounting loop of the mounting portion is bolted to the swinging bar 222 that moves up and down in conjunction with the collar frame (not shown) in an upright posture in which the mounting portion is vertical with the swinging bar 222 displaced upward. It has stopped. The swing bar 222 is installed on a pair of left and right interlocking arms 22 attached to a swinging shaft 221 supported on a frame (not shown) of a narrow width loom, and the interlocking arms 22 are connected to a saddle frame (not shown). Are linked by the link arm 223, so that it swings in the vertical direction and the front-rear direction in accordance with the vertical movement of the collar frame. Therefore, when the swing bar 222 is lowered from the upright posture, the displacement guide 2 is displaced downward while being tilted forward.

  As described above, the displacement guide 2 is displaced downward while tilting forward, so that when displaced, the displacement guide 2 is displaced to the lower end corner 212 of the inclined engagement portion 21 closest to the holding guide 33. In the state where the weft yarn 12 is wound around (see FIG. 4) and is displaced downward, the upper end corner portion 211 of the inclined engaging portion 21 closest to the holding guide 33 is displaced instead of the lower end corner portion 212. Multiply 12 (see Figure 10). As described above, when the displacement guide 2 is displaced up and down, the portion where the displacement weft 12 is wound around the displacement guide 2 changes (FIG. 4 and FIG. 10 comparison), thereby smoothly changing the supply path of the displacement weft 12. In addition, it is possible to suppress a change in tension of the displacement weft yarn 12 to be hung around.

  A mode in which the supply path of the displacement weft 12 is switched up and down with respect to the fixed weft 11 will be described in the order of the displacement guide 2 being displaced upward and the displacement guide 2 being displaced downward. In the state in which the displacement guide 2 is displaced upward, as shown in FIGS. 2 to 4, the fixed weft 11 is hung horizontally from the supply means to the holding guide 32, and from the holding guide 32 to the guide hole 311 of the needle 31. The needle 31 is inserted in the swivel plane. On the other hand, the displacement weft 12 is hung from the supply means to the lower end corner portion 212 of the displacement guide 2, hung around the holding guide 33 while maintaining a downward slope toward the front, and the needle 31 is inserted into the guide hole 311 of the needle 31. It is inserted from above the turning surface. That is, since the lower end corner portion 212 of the displacement guide 2 is located above the holding guide 32, the supply path of the displacement weft 12 is above the fixed weft 11 (see FIG. 4). The displacement guide 2 is not displaced while the needle 31 feeds the fixed weft yarn 11 and the displacement weft yarn 12 between the warp yarns 13, so that the upper positional relationship is maintained in the supply path of the displacement weft yarn 12 with respect to the fixed weft yarn 11.

  When the needle 31 starts to pivot, as shown in FIG. 5, the fixed weft 11 inserted through the guide hole 311 in the pivot surface of the needle 31 is hung on the needle 31 along the guide groove 312 extending from the guide hole 311. It is fed between the warps 13 so as to turn. On the other hand, the displacement weft 12 inserted through the guide hole 311 from above the turning surface of the needle 31 does not follow the guide groove 312 and is completely separated from the supply path of the fixed weft 11. Then, when the fixed weft 11 and the displacement weft 12 are disengaged from the holding needle 3 and finished feeding, the fixed weft 11 is fed between the warps 13 within the turning surface of the needle 31 as seen in FIGS. However, the displacement weft 12 is fed between the warp 13 from above the fixed weft 11. Thereafter, when the needle 31 returns to the original position and the barb 34 strikes the fixed weft thread 11 and the displacement weft thread 12, the displacement weft thread 12 is woven into the upper stage and the fixed weft thread 11 is woven into the lower stage.

  After the feed of the fixed yarn 11 and the displacement weft yarn 12 is finished and the rod 3 is driven, when the rod frame moves up and down and the vertically divided warp yarns 13 are exchanged, as shown in FIGS. 8 to 10, the displacement guide 2 is displaced downward. As described above, the fixed weft 11 is horizontally wound around the holding guide 32 from the supply means, and is inserted from the holding guide 32 into the guide hole 311 of the needle 31 within the turning surface of the needle 31. On the other hand, the displacement weft 12 is hung from the supply means to the upper end corner portion 211 of the displacement guide 2, hung around the holding guide 33 while maintaining an upward gradient toward the front, and is inserted into the guide hole 311 of the needle 31. Inserted from below the 31 swivel plane. That is, since the upper end corner portion 211 of the displacement guide 2 is positioned below the holding guide 32, the supply path of the displacement weft 12 with respect to the fixed weft 11 is downward (see FIG. 10). Since the displacement guide 2 is not displaced while the needle 31 feeds the fixed weft 11 and the displacement weft 12 between the warps 13, the supply path of the displacement weft 12 with respect to the fixed weft 11 maintains the lower positional relationship.

  When the needle 31 starts to turn, as shown in FIG. 11, the fixed weft 11 inserted into the guide hole 311 in the turning surface of the needle 31 is aligned with the guide groove 312 extending from the guide hole 311 as described above. It is fed between the warps 13 so as to hang around 31. On the other hand, the displacement weft 12 inserted into the guide hole 311 from below the turning surface of the needle 31 reaches the guide hole 311 from the holding guide 33 through the guide groove 312. Divided into Then, when the fixed weft 11 and the displacement weft 12 are disengaged from the holding needle 3 and finished feeding, the fixed weft 11 is fed between the warps 13 within the turning surface of the needle 31 as seen in FIGS. However, the displacement weft 12 is fed between the warp 13 from below the fixed weft 11. Thereafter, when the needle 31 returns to the original position and the barb 34 strikes the fixed weft 11 and the displacement weft 12, the fixed weft 11 is woven into the upper stage and the displacement weft 12 is woven into the lower stage.

Thus, the narrow weaving machine of this example changes the supply path of the displacement weft 12 up and down with the fixed weft 11 sandwiched up and down every time the warp 13 divided up and down by the vertical movement of the reed frame is changed to the warp 13 The ratio of the fixed weft yarn 11 and the displacement weft yarn 12 appearing on the surface of the weaving and narrow-width woven fabric 1 (see FIG. 1) is made uniform, and the change in surface color is made uniform. In the above description, the fixed weft thread 11 and the displacement weft thread 12 have been described as being clearly switched at the upper and lower stages, but in actuality, the fixed weft thread 11 and the displacement weft thread 12 are not clearly switched at the upper and lower stages, and the positional relationship between them is complicated. In this way, the fixed weft yarn 11 and the displacement weft yarn 12 appear irregularly evenly on the surface, but the narrow woven fabric 1 of the present invention is uniform in surface color change. And increase the value of the product.
