JP6006616B2 - Tatami mat and its manufacturing method - Google Patents

Description

  The present invention relates to a tatami mat and a manufacturing method thereof.

  In recent years, a tatami table using paper instead of 藺 草 has been proposed from the viewpoint of providing features and functions that tatami mats do not have. For example, Patent Document 1 discloses a tatami table manufactured by cutting a paper mainly composed of coniferous wood fibers into a width of 20 to 40 mm, twisting the paper into a cylindrical shape, and then weaving with a loom. Yes.

Japanese Patent No. 2885658

  However, the above-described tatami mats using paper have a problem that it is difficult to give a natural texture of grass and in particular, they are inferior in softness. Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a tatami table that can provide a natural softness while using paper, and a method for manufacturing the same.

  The method for producing a tatami surface according to the present invention includes a first step of arranging a plurality of warps in parallel, and a long paper having a predetermined width as a weft, with no twist being applied to the plurality of warps. A second step of weaving and a third step of beating the weft, and weaving is performed by repeating the second and third steps.

  According to this configuration, when weaving, a long paper having a predetermined width is used as the weft, and the weft is woven into the warp without being twisted. Then, by weaving the woven weft, the paper of a predetermined width is crushed to adjust the shape as a weft. Thereby, it does not become hard like the thread | yarn which twisted paper, and softness can be provided to a tatami surface. As a result, it is possible to improve the touch like natural camellia. In addition, since a cocoon is formed on the weft when it is crushed, the cocoon can give an appearance texture similar to natural cocoon. Therefore, it is possible to manufacture a tatami mat table having a texture like a soft natural grass while using paper. Furthermore, when using paper, conventionally twisted paper is used. However, if twisted according to the method of the present invention, the process of twisting the paper is not performed, so that the manufacturing time can be greatly shortened. . In addition, “do not twist” means that a so-called fiber is not twisted. In the process of transporting the weft, for example, when passing through a guide or the like, the width is somewhat narrowed or broken. However, this is included in “not twisted”.

  In the said manufacturing method, the width | variety of the said weft before the said hammering is given can be 3-100 mm. This is because if it is larger than 100 mm, the wefts cannot be sufficiently crushed at the time of hammering, and a gap may be formed between adjacent wefts. On the other hand, if it is smaller than 3 mm, the weft is too crushed and it is difficult to produce a texture like natural weeds.

  In the said manufacturing method, it is preferable to arrange | position 8-20 wefts per 1 cm in the direction of the said warp, and it is still more preferable to set it as 10-15. This is because if the number is 20 or less, the tatami table can be woven with a small number of wefts, so that the cost can be reduced and the manufacturing time can be greatly shortened. Further, if the number is less than 8, there is a possibility that a gap is formed between adjacent wefts, which is not preferable.

    In the manufacturing method, a plurality of connecting yarns extending in parallel along the warp direction are further provided so as to connect the plurality of wefts arranged in the warp direction, and the plurality of connecting yarns are provided in the weft yarns. It can be woven into a place arranged on the lower side of the warp.

  By providing such a connecting thread, it is possible to prevent a gap from being formed between adjacent wefts even when a load is applied to the tatami mat. In particular, in the direction of the warp, for example, when arranging about 12 wefts per 1 cm, a gap is likely to be generated depending on the load, but this can be prevented by providing a connecting yarn. .

  Moreover, the tatami mat table according to the present invention is manufactured by any of the manufacturing methods described above.

  According to the present invention, it is possible to give a natural texture of grass while using paper.

  Hereinafter, a method for manufacturing a tatami mat according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic plan view (a) and a sectional view (b) showing an embodiment of a method for manufacturing a tatami mat according to the present invention.

<1. Weft>
First, various types of pulp can be used as the weft. For example, pulp mainly composed of coniferous trees can be used. Specifically, conifers such as northern pine, spruce, pine, and cedar can be used. And the roll formed with such a pulp is prepared. The basis weight of this pulp can be, for example, 15 to 60 g / m ² . And while extending | stretching this roll, it cut | judges to a predetermined | prescribed width | variety and produces | generates several rolls with a small width | variety. The width of the roll cut at this time is preferably, for example, 3 to 100 mm, more preferably 5 to 30 mm, and particularly preferably 10 to 19 mm.

<2. Warp>
In the weaving in the present embodiment, various warps can be used. For example, in addition to natural fibers such as cotton yarn and hemp yarn, resin fibers such as polypropylene, polyethylene, and vinyl chloride can be used. it can. Although the diameter of a warp can be set suitably, it can be set as about 1.0-2.0 mm, for example. The warp may be a single yarn, but a plurality of yarns may be twisted.

<3. Weaving>
As the weaving process, a known process using a known weaving machine for producing a tatami surface can be adopted. In the present embodiment, a description will be given of a case in which a square weave in which one warp is arranged in one eye is used. First, a plurality of warp yarns 1 are arranged in parallel by a known method (first step), the weft yarn 2 is inserted (second step) while performing the opening movement of the warp yarn 1 (second step), and the beating is performed (third step). ). At this time, the inserted weft 20 (here, for convenience of explanation, the reference sign of the warp before being crushed is 20) is unwound from the roll described above, but as shown in FIG. Instead, it is inserted between the warp yarns 1 with the above-mentioned width. Following this, as shown in FIG. 2, the weft 20 is beaten with the scissors 5. The cocoon 5 can be a known cocoon, and is provided with a plurality of cocoon wings although not shown. Thereby, the weft 20 is crushed by the reed 5 and the width is reduced. At this time, the density of the weft 2 is beaten so that 8 to 20, preferably 10 to 15 wefts are arranged in 1 cm in the warp direction X. For example, in the example of FIG. 1, about 13 wefts are woven per 1 cm. The beating is performed each time one weft 2 is inserted. However, after a plurality of wefts 2 are inserted, the plurality of wefts 2 can be beaten.

  Moreover, the weft 2 can also be connected with the connection yarn 3 knitted in parallel with the warp 1 as needed. As shown in FIG. 3, the connecting yarn 3 is woven into a portion of the back surface of the tatami surface that is not exposed to the front side of the weft yarn 2, that is, a portion below the warp yarn 1. As the weaving method, for example, a known weaving method (sewing method) such as straight stitching or decorative stitching can be adopted, and for example, it can be woven together with the weft 2 by a known method. As the connecting yarn 3, a yarn made of the same material as the warp, such as cotton yarn or hemp yarn, can be used. Moreover, in order not to see on the front side of a tatami surface, the one where the diameter of a thread | yarn is thin is preferable, for example, can be 0.5-1.0 mm.

<4. Features>
As described above, according to this embodiment, when weaving, a long paper having a predetermined width is used as the weft 2 and the weft 20 is woven into the warp without twisting. It is out. Then, by weaving the woven weft 20, the paper is crushed and the shape as a weft is arranged. Thereby, it does not become hard like the thread | yarn which twisted paper, and softness can be provided to a tatami surface. As a result, it is possible to improve the touch like natural camellia. Further, the weft 2 is formed with a cocoon when it is crushed, so that the cocoon can give an appearance texture similar to natural cocoon. Therefore, while using paper, unlike a twisted paper, it is possible to produce a tatami surface with a soft natural vine texture.

  Compared to the case of weaving a tatami surface using twisted paper as in the conventional example, there is no step of twisting the paper, so that the manufacturing time can be greatly shortened and the manufacturing cost can be reduced.

  When the connecting yarn 3 as described above is used, even when a load is applied to the tatami mat, it is possible to prevent a gap from being formed between the wefts and spreading. Therefore, by using the connecting yarn 3, the density of the weft 2 can be reduced, and for example, it can be 15 yarns / cm or less in the warp direction X. As described above, when the density of the weft is reduced, the amount of weft used in one tatami mat is reduced, so that the cost can be reduced and the manufacturing time can be greatly shortened.

  When paper is used as a weft, a tatami mat having a width larger than that of a tatami mat using normal natural weeds can be produced. That is, since natural camellia has only a length of approximately 1.0 to 1.5 m, the width of the manufactured tatami mat is inevitably this width, but when wefts are formed with paper, Since there is no restriction on the length of the weft, the width of the tatami mat can be increased. For example, it is possible to manufacture a tatami mat table having a width of 2.0 m or more. Thereby, the manufacturing efficiency is greatly improved.

<5. Modification>
The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the spirit of the present invention.

  In the above-described embodiment, the example using the mesh weaving has been described, but the method is not particularly limited. For example, it can be woven with various weaving methods such as ordinary weaving, ordinary weaving, various weaving, large weaving, pulling weaving, twill weaving, etc. The number of is also not particularly limited.

  Examples of the present invention will be described below. However, the present invention is not limited to the following examples. The tatami mat of this example was manufactured by using the following materials.

(1) A warp yarn having a diameter of about 1.5 mm was used. This warp is a twist of a plurality of yarns. The warp interval is about 5 mm.
(2) Weft Using a pulp mainly composed of conifers as a material, a roll around which a pulp having a width of about 15 mm was wound was formed. The basis weight is about 20 g / m ² .
(3) Linking thread Cotton thread with a diameter of about 0.5 mm was used, and weft was straight stitched at the point that appeared on the back of the tatami mat.
(4) Weft density About 12 wefts were arranged per 1 cm in the warp direction.

  As a result of weaving with the above materials and using a weave with one warp arranged in one eye, tatami mats as shown in FIGS. 4 and 5 were woven. FIG. 4 shows the surface of the woven tatami mat and FIG. 5 shows the back side. When the surface was touched, the paper was not twisted, so there was no hardness and the texture felt soft. In addition, as shown in FIG. 4, the wefts were moderately wrinkled and appeared to look like natural camellia. As described above, 12 wefts are contained per 1 cm. Further, as shown in FIG. 5, since the wefts are connected to each other by the connecting yarn, a gap is prevented from being formed between the wefts.
