Description

  The present invention relates to a tatami rim characterized by a weft.

  The tatami edge, which is a narrow woven fabric, is required to have some rigidity. For this reason, the structure and weaving method of warp and weft are devised, and one of them is an attempt to use monofilament yarn for the weft. However, according to this, although the yarn is tense and stiffened, when a polyester yarn having good slippage is used for the warp, the warp may slip on the weft during use, so-called misalignment may occur. On the other hand, when a multifilament yarn is used for the weft, the yarn is too soft and the rigidity does not come out.

For this reason, as seen in the following Patent Document 1, it has been proposed to use a multifilament yarn and a monofilament yarn that are aligned with each other (no twisting). However, since this is aligned, the monofilament yarn may be in contact with the warp, and in this case, misalignment is also caused.

  The problem to be solved by the present invention is to take advantage of multifilament yarn and monofilament yarn to provide a tatami rim that is reasonably stiff and does not cause misalignment, and at the same time realizes a glossy tatami rim It is something to try.

  Under the above-described problems, the present invention is woven on a tatami edge by aligning a multifilament yarn in which atypical cross-section fibers are bundled and a monofilament yarn made of a single fiber into a weft yarn with respect to the warp yarn. A multi-filament yarn according to claim 2, wherein the multifilament yarn is a bundle of atypical hollow fibers, and the weft yarn is a multifilament yarn and a monofilament yarn. The structure which twists is provided.

  According to the invention of claim 1, since the multifilament yarn is a bundle of atypical cross-section fibers, even if it is in contact with the warp, there are many contact points, so it is difficult to slip and misalignment is difficult to occur. . In addition, since it is an atypical cross-section fiber, it has a high aesthetic effect because it is glossy or emits a different color depending on the viewing direction. Further, according to the invention of claim 2, it becomes light, and according to the invention of claim 3, there is an advantage that the misalignment hardly occurs and the strength is increased.

  FIG. 3 is a partially enlarged view of the tatami edge. The tatami edge is woven by a loom so that the weft 2 basically forms a plain weave structure on the warp 1 extending in the longitudinal direction of the woven fabric. At this time, the pattern is usually raised using a part of the warp 1 or another warp. In this case, the warp yarn 1 is made of nylon, polyester, acrylic, rayon, acetate, or the like, and monofilament yarn only, multifilament only, or a mixture of both.

  The material of the weft 2 is the same, but polyester-based materials are often used. As the weft 2 according to the present invention, a multifilament yarn A in which atypical cross-section fibers are bundled is employed. FIG. 1 is an enlarged cross-sectional view of the multifilament yarn A. Thus, each fiber has a non-circular shape with a non-circular cross section. The shape and density of the atypical shape are not particularly limited. Each fiber is bundled into a predetermined number (about 20 to 60) to form one multifilament yarn A.

  FIG. 2 is a cross-sectional view showing another example of the multifilament yarn B. In this example, the inside of each fiber is configured to be hollow. According to this, there is an advantage that the woven fabric becomes light. Also in this case, the outer shape and the inner shape are not limited, and the number of bundles is the same as described above. On the other hand, the monofilament yarn C is composed of a single fiber, and a polyester-based yarn is often used.

  As for the thickness of the multifilament yarns A to B and the monofilament yarn C used for the weft yarn 2, in the case of a normal tatami edge, the former is about 200 denier and the latter is about 150 denier, but is not limited thereto. . The warp yarn 1 is the same. In the case of a multifilament yarn and a monofilament yarn alone, about 300 to 400 deniers are used, and in both cases, about 200 deniers and 150 deniers are adopted. used.

  The warp yarn 1 and the weft yarn 2 are used to be woven into a tatami edge by a known loom. At this time, the multifilament yarn and the monofilament yarn of the weft yarn 2 are aligned. However, the two wefts 2 may be twisted. Since the function of drawing or twisting is permanently installed in the weft supply section of the loom, it may be set to any one of them. In addition, when twist is added, misalignment is further suppressed, the woven fabric is well tightened, and the strength is increased.

It is sectional drawing of the multifilament yarn which shows an example of this invention. It is sectional drawing of the multifilament yarn which shows another example of this invention. It is sectional drawing of the monofilament yarn which shows an example of this invention. It is a partially expanded view of a tatami edge.
