Description

  The present invention relates to a three-layer structure gauze fabric capable of expressing a pattern.

  Recently, a gauze fabric in which a plurality of gauze is laminated is often used as a towel or a handkerchief. The gauze fabric is generally referred to as a gauze towel or a gauze handkerchief, and is excellent in water absorption and soft to the touch. Therefore, it is suitable for wiping the skin such as when wiping sweat.

  The gauze stipulated by the Japanese Pharmacopoeia is a white cloth obtained by plain weaving, degreasing and bleaching cotton (men) yarn. However, as described above, the gauze fabric generally used as towels is colored and displays a pattern. What was done is requested.

  As a gauze fabric expressing such a pattern, for example, Patent Document 1 proposes a jacquard multi-gauze fabric.

The multiple gauze fabric (three-layer structure gauze fabric) described in Patent Document 1 is a triple gauze provided with three layers, each using three colors as warp and weft, and the weft as the above three layers. The warp yarns are allowed to appear and disappear at the same time, and the warp yarns are crossed with the weft yarns in one layer and then crossed with the weft yarns in another layer. And thereby, it can be set as the textile fabric which expressed the pattern with the thread | yarn of the said 3 colors.
Japanese Patent Laid-Open No. 11-323893

  However, in the conventional multi-gauze fabric (three-layer structure gauze fabric), the color of the yarn arranged in the intermediate layer appears on the front and back surfaces. For this reason, there exists a possibility of damaging the pattern of the surface or the back surface. Incidentally, when viewed from the front surface (or the back surface), the color of the back surface layer (or the front surface layer) is blocked by the presence of the intermediate layer, so that the front surface (or the back surface) is not significantly affected.

  Therefore, the present invention has been made in view of the above points, and the object thereof is not greatly affected by the color yarn of the intermediate layer (intermediate layer), and the three-layer structure can independently represent the front and back patterns. It is to provide a gauze fabric.

  The three-layer structure gauze fabric according to the present invention is a fabric in which three layers of upper, middle, and lower layers are stacked, and the upper, middle, and lower warp yarns are all composed of achromatic gauze yarns, The middle and lower layer wefts are composed of colored gauze yarns (hereinafter sometimes referred to as colored gauze wefts), and the wefts of each layer are crossed at any position with either the upper, middle or lower layer The intermediate layer is further provided with an achromatic bulky yarn at an arbitrary pitch in the weft direction and appropriately woven into the warp of the middle layer. To do. The gauze yarn is a yarn used for gauze and refers to 15th to 60th cotton yarn. The “colored gauze yarn” includes not only chromatic colors but also achromatic colors.

  In the following description, for convenience, the upper layer side may be described as the front and the lower layer side as the back.

  In the present invention, the colored gauze in the weft direction is repositioned to the upper, middle, and lower layers to draw a pattern on the front and back surfaces of the fabric, and the achromatic color (white, black, gray) is used for the warp. The color of the weft is not impaired. The color of the colored gauze weft located in the upper layer appears on the front side, the color of the colored gauze weft located in the lower layer appears on the back side, and the colored gauze weft located on the middle layer is hidden by being sandwiched between the upper and lower layers, the front side and the back side A separate pattern will be drawn.

  In the present invention, an achromatic bulky yarn is arranged in the middle layer, and the bulky yarn has a larger appearance than the colored gauze weft of the middle layer, so that the color of the colored gauze weft becomes inconspicuous. As a result, when viewed from the front side, the color of the middle layer to the upper layer is prevented, and similarly, when viewed from the back side, the color of the middle layer to the lower layer is prevented. In order to exhibit such an effect, the thickness of the bulky yarn is preferably 300 to 2100 dtex. More preferably, it is 600 dtex or more and 1700 dtex or less.

  Incidentally, as a matter of course, when viewed from the front side, the color of the lower layer is blocked by the middle layer when viewed from the back side and does not appear on the opposite side.

  In addition, when the bulky yarn is arranged in the middle layer as described above, the volume feeling is excellent. The gauze fabric has an advantage of a soft feel and good hygroscopicity, but the softness and hygroscopicity are further improved by the volume feeling of the bulky yarn.

  Furthermore, in the present invention, it is preferable that the bulky yarn of the middle layer is inserted at a pitch of 1 to 3 with respect to the two middle layer wefts (colored gauze wefts).

  This is because if the number of the bulky yarns inserted is too small, the above-described action of preventing color transfer to the upper and lower layers may be poor. On the other hand, if the number of bulky yarns inserted is too large (for example, bulky yarns are inserted at four pitches relative to two middle layer wefts), the number of yarns inserted in the weft direction in the middle layer will be too large. This is because there is a concern of damaging the soft feel when inserting like a plain weave structure.

  Moreover, in this invention, it is preferable that the bulky yarn of the said middle layer has a location where 3-14 skips with respect to the said middle layer warp.

  That is, when inserting the bulky yarn in the weft direction, it is preferable to cross 3 to 14 warp yarns, for example, like a twill weave. For example, 1/2 twill (a structure in which a bulky yarn passes continuously over two warps, then passes under one warp and repeats this), 1/3 twill, 1/4 twill, etc. Is mentioned. Thereby, the bulky yarn comes to float on the one surface side in the middle layer. In particular, if the middle layer colored gauze wefts and warps have a plain weave structure, the part where the bulky yarns float as described above tends to be located above (outside) the middle layer colored gauze wefts. The gauze weft will be hidden. Therefore, when viewed from the front side, it is difficult to see the color of the middle layer through the upper layer.

  Further, when the bulky yarn is inserted in this manner, the bulky yarn is also floated on the other side of the middle layer. Therefore, the front and back sides on which the floated yarn appears for each bulky yarn may be alternately changed. Specifically, for example, one bulky yarn is first inserted with a 1/3 twill, and the next bulky yarn is inserted with a 3/1 twill, and this is repeated. This makes it possible to form a part where the bulky yarn is floated on both sides of the middle layer, thereby hiding the colored gauze wefts of the middle layer on both sides. Therefore, it is possible to satisfactorily prevent the middle layer from being colored in the upper layer and the lower layer.

  Furthermore, when inserting the bulky yarn in the weft direction, for example, satin weave, the number of texture points (intersection points) with respect to the warp may be reduced, and the texture points may be dispersed to float the bulky yarn. As described above, the number of warp yarns when floating like this satin weave is preferably 3 to 14. In this case as well, in order to float the bulky yarns on both sides of the middle layer, it is preferable to alternately change the front and back sides where the floated yarn appears for each bulky yarn. As a result, the middle layer color transfer to the upper layer and the lower layer is satisfactorily prevented.

  In addition, when bulky yarns are inserted by interlacing each warp like a plain weave, there is a concern that the binding force of the bulky yarns by the warp will become stronger and the soft texture of the gauze fabric will be impaired. When a bulky yarn is inserted as in Riyako weaving, the binding force with the warp is small and a soft texture is obtained.

  And in order to satisfactorily exert the concealing effect and soft texture effect of the colored gauze wefts in the middle layer, it is preferable to set the number of warp yarns to be 3 or more, more preferably to cross the bulky yarns as described above Is 4 or more.

  On the other hand, if the interval at which the bulky yarn intersects with the warp is too large, the bulky yarn will be twisted at the floating part, and the colored gauze weft of the middle layer will not be concealed. The number is preferably 14 or less, more preferably 11 or less. More preferably, it is 7 or less.

  In the three-layer structure gauze fabric according to the present invention, not only the opposite layer (the lower layer when viewed from the upper layer side, the upper layer when viewed from the lower layer side), but also the color of the yarn disposed in the middle layer is prevented. Therefore, the front and back patterns can be independently represented regardless of the color of the middle layer.

<Embodiment 1>
FIG. 1 is a view showing a three-layer structure gauze fabric according to Embodiment 1 of the present invention. (A) of FIG. 1 is the figure seen from the front side (upper layer side) of a 3 layer structure gauze fabric, Comprising: The color which appears there is represented by A-E. 1B is a cross-sectional view in the weft direction of the three-layer structure gauze fabric, and FIG. 1C is a cross-sectional view in the warp direction. In FIG. 1, (b) corresponds to the lower row (A, B, C) in (a), and (c) corresponds to the right column (B, E, C) in (a). Further, in the drawing, in order to make the difference between the yarns easy to understand, each yarn is represented by using a solid line, a broken line, an alternate long and short dash line, and a thick line.

  As shown in FIGS. 1B and 1C, the three-layer structure gauze fabric of Embodiment 1 is a triple fabric based on plain weave, and a bulky yarn (cotton yarn F) is further added to the middle layer. It has been inserted.

  In FIG. 1B, the upper layer is the upper layer, the middle layer is the middle layer, and the lower layer is the lower layer. In FIG. 1C, the layer shown on the left is the upper layer, the layer shown in the middle is the middle layer, and the layer shown on the right is the lower layer.

  The wefts A, B, C, D and E are colored gauze yarns, for example, colored gauze weft A is blue, colored gauze weft B is pink, colored gauze weft C is green, colored gauze weft D is orange, colored The gauze weft E is white. Warps A, A, and U are all white gauze threads. Cotton yarn (bulky yarn) F is white and is a textured yarn (668 dtex) made of polyester.

  The range surrounded by the two-dot chain line in FIG. 1 (c) corresponds to the woven structure in the range surrounded by the two-dot chain line in FIG. 1 (b).

  First, the running state (arrangement) of warps A, A, and C will be described.

  As shown in FIG. 1 (c), the warp yarns are located in the lower layer in the upper part of the figure, in the upper layer in the middle of the figure, and in the lower layer in the lower part of the figure. The warp yarn is located in the upper layer in the upper part of the drawing, is located in the lower layer in the middle of the drawing, and is located in the upper layer in the lower part of the drawing. The warp a is located in the middle layer in any of the upper part, the middle part, and the lower part.

  As described above, the warp yarns a and u are arranged so as to cross the positions of the upper and lower layers, so that the layers of the triple woven fabric are integrated without being separated. In the first embodiment, the configuration in which the positional relationship between the upper, middle, and lower layers is changed only for the warps a and c is not limited to this, and the positional relationship between the upper, middle, and lower layers is also changed. You may comprise like this.

  Next, the running state (arrangement) of the cotton yarn F will be described.

The cotton yarn F is inserted at one pitch with respect to one middle layer colored gauze weft yarn (that is, the cotton yarn F is inserted at two pitches with respect to two middle layer colored gauze weft yarns). . Further, the cotton yarn F is inserted like a satin weave, and the cotton yarn F ₁ having a floating portion on the front side first floats on three warp yarns (3 skips three warp yarns), and then below one warp yarn I. Then, it floats on three warp threads, sinks under one warp thread, and this is repeated. In the cotton yarn F ₂ having a part that floats on the back side, contrary to the above-described cotton yarn F ₁ , first, it sinks under three warps (3 skips three warps) and then floats on one warp. Then, it sinks under three warps and floats on one warp and repeats this.

The cotton yarn F (F ₁ , F ₂ ) is bulky and floats with three warps a flying as described above, so it is positioned so as to cover the middle colored gauze weft, and the middle colored gauze weft Hide.

  Next, the running state (arrangement position) of the colored yarn (colored gauze weft) will be described.

  As shown in FIG. 1B, the colored gauze weft A is located in the upper layer on the left side of the figure, located in the middle layer in the middle of the figure, and located in the lower layer on the right side of the figure. The colored gauze weft B is located in the lower layer on the left of the figure, located in the upper layer in the middle of the figure, and located in the middle layer on the right of the figure. The colored gauze weft C is located in the middle layer on the left of the figure, located in the lower layer in the middle of the figure, and located in the upper layer on the right of the figure. In this way, the colored gauze wefts A, B, and C cross each other at any position (positions indicated by arrows α and β) with any of the upper, middle, and lower layers.

  In each part (left, middle, right), a plain weave structure is formed by crossing with the warps a, i, and u.

  Since warps a, i, and u are all white, when colored gauze wefts A, B, C, D, and E are interwoven, the color of the colored gauze wefts should appear slightly pastel. It becomes.

  And when it sees from the front side (upper layer side), the color of the colored gauze weft located in the upper layer is visually recognized on the front side of the gauze fabric. Specifically, the blue color of the colored gauze weft A appears on the left side of FIG. 1B, the pink color of the colored gauze weft B appears in the middle, and the green color of the colored gauze weft C appears on the right side. It looks like the color scheme shown. The color of the yarn located in the lower layer is blocked by the middle layer and does not appear in the upper layer. In addition, the colored gauze weft located in the middle layer is also hidden by the cotton yarn F and hardly appears in the upper layer.

  On the other hand, when viewed from the back side (lower layer side), the color of the colored gauze weft located in the lower layer is visually recognized on the back side of the gauze fabric, and the left side of FIG. The green color of the gauze weft C appears and the blue color of the colored gauze weft A appears on the right. Similarly to the above, the color of the yarn located in the upper layer is blocked by the middle layer and does not appear in the lower layer. In addition, the colored gauze weft located in the middle layer is also hidden by the cotton yarn F, so that it hardly appears in the lower layer. .

  1C corresponds to the right column in FIG. 1A, but when viewed from the front side (upper layer side), the colored gauze weft C green, the colored gauze weft E white, and the colored gauze weft B viewed from below. The pink color appears, and the colors of the lower and middle layers hardly appear on the upper layer.

  Note that, since it has a three-layer structure, the color scheme in one latitude direction is limited to three colors, but the color scheme in the latitude direction at different locations as described above can be variously changed (as shown in FIG. 1 (a)). In the portion, there are three colors of A, B, and C, but in the middle portion, the colors D and E can be used), so various patterns can be drawn.

  In addition, in the first embodiment, since the cotton yarn F is arranged in the middle layer, the three-layer structure gauze fabric is excellent in volume feeling and more excellent in soft feeling and moisture absorption.

  Although FIG. 1 shows a pattern in which colors are arranged in a lattice pattern, an arbitrary pattern can be configured by changing colored gauze wefts to upper, middle, and lower layers at arbitrary positions. In other words, colored gauze wefts of a certain color are preferably positioned in the upper layer when expressed as a front side pattern, positioned in the lower layer when expressed as a back side pattern, and positioned in the middle layer when desired to be hidden.

<Embodiment 2>
FIG. 2 is a cross-sectional view in the weft direction representing a three-layer structure gauze fabric according to Embodiment 2 of the present invention.

  In the second embodiment, compared to the first embodiment, the interval at which the colored gauze wefts change the positions of the upper, middle, and lower layers is longer, and the color of the colored gauze wefts appears on the front side / back side in a wide range. . Further, the number of cotton yarns F that warp warps is increased to five.

  As described above, for the wefts that are colored yarns, the positions to be changed between the upper, middle, and lower layers can be arbitrarily set, and the range of drawing in a certain color can be set variously.

  Further, in the second embodiment, the number of the cotton yarns F that warp the warp yarns is larger than that in the first embodiment, so that the restraint with the warp yarns is reduced and a softer texture is exhibited.

  As described above, the three-layer structure gauze fabric according to the present invention has been specifically described with reference to the drawings showing examples. However, the present invention is not limited to the illustrated examples but can be applied to the above-described purpose. The present invention can be carried out with appropriate modifications, all of which are included in the technical scope of the present invention.

  For example, in the above embodiment, the warp yarns are provided with scattered locations where the positional relationship between the upper, middle, and lower layers is changed, but even if the warp yarn does not change the positional relationship between the upper, middle, and lower layers. good. Even in this case, the colored gauze wefts change the positional relationship between the upper, middle, and lower layers while drawing a pattern, so that the integrity of the upper, middle, and lower layers can be ensured.

  In the first embodiment, the upper, middle and lower colored gauze wefts are shown in the case where the positions of all three are changed at the α and β positions. However, the present invention is not limited to this. The lower layer may not be replaced, or the colored gauze wefts may be replaced at the upper and lower layers, and the middle layer may not be replaced.

  The insertion pitch of the bulky yarn (cotton yarn F) is not limited to the above embodiment. For example, the pitch of the bulky yarn (cotton yarn F) may be inserted at one pitch with respect to the two middle layer wefts. good.

  The insertion mode of the cotton yarn (bulky yarn) F is not limited to the above-described embodiment. For example, a satin weave with 6 warps or 8 warps may be used.

It is a figure showing the 3 layer structure gauze textiles concerning Embodiment 1 of the present invention. It is sectional drawing of the weft direction showing the 3 layer structure gauze fabric based on Embodiment 2 of this invention.
