Description
本発明は、セメント製品や樹脂製品等に貼着又は埋設して用いる成型用メッシュ織物の製造方法に関するものである。 The present invention relates to a method for producing a mesh woven fabric for molding, which is used by being attached or embedded in a cement product, a resin product, or the like.
従来より、セメントで成型される製品に、メッシュ織物を貼着又は埋設して、セメント製品を強化することが行われている（特許文献１）。また、電気冷蔵庫、電子レンジ及び電気掃除機等の電子・電気機器の樹脂製筐体にメッシュ織物を貼着又は埋設して、樹脂製筐体を強化することも行われている。 Conventionally, a mesh woven fabric has been attached or embedded in a product molded from cement to strengthen the cement product (Patent Document 1). Further, a mesh woven fabric is attached or embedded in a resin housing of electronic / electrical equipment such as an electric refrigerator, a microwave oven, and a vacuum cleaner to strengthen the resin housing.
特許文献１には、ガラス繊維や合成繊維よりなるストランドを経糸及び緯糸に用いて、製織したメッシュ織物が記載されている。しかしながら、かかる織物は経糸と緯糸とが浮沈しながら交錯しているものであり、セメント製品又は樹脂製品表面が平滑に仕上がりにくいということがあった。また、経糸と緯糸の間に目（隙間）が存在するため、メッシュ織物が目視できる状態で貼着又は埋設されていると、織物中の目が混入し、不鮮明な織物柄となって美装感に優れた製品が得られにくいということがあった。 Patent Document 1 describes a mesh woven fabric woven by using strands made of glass fibers or synthetic fibers as warp threads and weft threads. However, in such a woven fabric, the warp and the weft are interlaced while floating and sinking, and the surface of the cement product or the resin product may be difficult to finish smoothly. In addition, since there are eyes (gap) between the warp and weft, if the mesh woven fabric is attached or buried in a visible state, the eyes in the woven fabric will be mixed and the woven fabric will be unclear and beautiful. Sometimes it was difficult to obtain a product with a good feeling.
本発明の課題は、セメント製品や樹脂製品等に貼着又は埋設したときに、織物を平滑化しうると共に、目が生じにくいようにしたメッシュ織物の製造方法を提供することにある。 An object of the present invention is to provide a method for producing a mesh woven fabric, which can smooth the woven fabric and prevent the appearance of eyes when it is attached or embedded in a cement product, a resin product, or the like.
本発明は、特定の経糸及び緯糸を用いると共に、特定の方法で製織してメッシュ織物を得ることにより、上記課題を解決したものである。すなわち、本発明は、芯成分が高融点重合体よりなり、鞘成分が低融点重合体よりなる芯鞘型複合繊維を複数本引き揃えてなるマルチフィラメント糸を得る工程と、前記マルチフィラメント糸に甘撚を施して経糸及び緯糸を得る工程と、ｎ（ｎは２以上の正数である。以下同じ。）本の経糸列Ａ群を同時に上に移動させたとき、該経糸列Ａ群と隣り合うｎ本の甘撚された経糸列Ｂ群を同時に下に移動させ、また、該経糸列Ａ群を同時に下に移動させたとき、該経糸列Ｂ群を同時に上に移動させて、該経糸列Ａ群と該経糸列Ｂ群の間に上下方向の隙間を設ける工程と、前記隙間の間に、甘撚された緯糸をｎ回打ち込むことによってメッシュ織物を製織する工程とよりなる成型用メッシュ織物の製造方法に関するものである。 The present invention solves the above-mentioned problems by using a specific warp and weft and weaving by a specific method to obtain a mesh woven fabric. That is, the present invention comprises a step of obtaining a multifilament yarn in which a plurality of core-sheath type composite fibers having a core component made of a high melting point polymer and a sheath component made of a low melting point polymer are aligned, and the multifilament yarn. When the process of sweet twisting to obtain warp and weft and the warp row A group of n (n is a positive number of 2 or more; the same applies hereinafter) are moved upward at the same time, the warp row A group and When n adjacent sweet-twisted warp row B groups are moved downward at the same time and the warp row A group is moved downward at the same time, the warp row B group is moved upward at the same time. For molding, which comprises a step of providing a vertical gap between the warp row A group and the warp row B group, and a step of weaving a mesh woven fabric by driving sweet-twisted weft yarns n times between the gaps. It relates to a method of manufacturing a mesh woven fabric.
本発明に用いる経糸及び緯糸は、マルチフィラメント糸に甘撚を施してなるものである。マルチフィラメント糸は、高融点重合体よりなる芯成分と、低融点重合体よりなる鞘成分とが芯鞘型に複合された芯鞘型複合繊維が複数本引き揃えられてなるものである。マルチフィラメント糸を構成する芯鞘型複合繊維の本数は任意であるが、一般的に５０本以上である。この本数が少ないと、経糸及び緯糸の幅を大きく広げにくくなる。また、マルチフィラメント糸の繊度も任意であるが、一般的に８００デシテックス以上である。マルチフィラメント糸の繊度が低すぎると、鮮明な織物柄を表現しにくくなる。芯成分と鞘成分の組み合わせとしては、ポリエチレンテレフタレート／ポリエチレン、ポリエチレンテレフタレート／ポリプロピレン、ポリエチレンテレフタレート／マレイン酸変性ポリエチレン、ポリエチレンテレフタレート／マレイン酸変性ポリプロピレン、ポリエチレンテレフタレート／（ポリエチレン及びマレイン酸変性ポリエチレンの混合物）、ポリエチレンテレフタレート／（ポリプロピレン及びマレイン酸変性ポリプロピレンの混合物）及びポリエチレンテレフタレート／低融点ポリエステル等の従来公知の組み合わせが挙げられる。芯成分と鞘成分の重量割合は、芯成分：鞘成分＝１：１〜５程度である。鞘成分として低融点重合体が用いられているのは、鞘成分を軟化又は溶融しやすくして、セメントや樹脂との接着性を向上させると共に、経糸と緯糸とを融着させるためである。また、芯成分として高融点重合体を用いられているのは、鞘成分が軟化又は溶融しても、芯成分に当初の繊維形態を保持させて、織物柄を表現しやすくするためである。 The warp and weft used in the present invention are made by applying a sweet twist to a multifilament yarn. The multifilament yarn is formed by arranging a plurality of core-sheath type composite fibers in which a core component made of a high melting point polymer and a sheath component made of a low melting point polymer are combined in a core-sheath type. The number of core-sheath type composite fibers constituting the multifilament yarn is arbitrary, but is generally 50 or more. If this number is small, it becomes difficult to greatly widen the width of the warp and weft. The fineness of the multifilament yarn is also arbitrary, but is generally 800 decitex or more. If the fineness of the multifilament yarn is too low, it becomes difficult to express a clear woven pattern. As a combination of core component and sheath component, polyethylene terephthalate / polyethylene, polyethylene terephthalate / polypropylene, polyethylene terephthalate / maleic acid-modified polypropylene, polyethylene terephthalate / maleic acid-modified polypropylene, polyethylene terephthalate / (mixture of polyethylene and maleic acid-modified polyethylene), Examples thereof include conventionally known combinations of polyethylene terephthalate / (mixture of polypropylene and maleic acid-modified polypropylene) and polyethylene terephthalate / low melting point polyester. The weight ratio of the core component and the sheath component is about 1: 1 to 5 of the core component: the sheath component. The low melting point polymer is used as the sheath component in order to soften or melt the sheath component easily, improve the adhesiveness to cement and resin, and fuse the warp and weft. Further, the reason why the high melting point polymer is used as the core component is that even if the sheath component is softened or melted, the core component retains the initial fiber morphology so that the woven fabric pattern can be easily expressed.
経糸及び緯糸は、マルチフィラメント糸に甘撚が施されてなるものである。甘撚を施す理由は、撚りを甘くすることにより、セメントや樹脂と一体化する際に、経糸及び緯糸の幅が拡がりやすくなり、織物自体が平滑化されると共に、織物の目が詰まって経糸及び緯糸間の目が消失するからである。甘撚は、一般的に撚り数が６０〜１２０Ｔ／Ｍ程度であり、特に５０〜７０Ｔ／Ｍであるのが好ましい。撚り数が多すぎると、セメントや樹脂と一体化する際に、経糸及び緯糸の幅が拡がりにくくなる。また、撚り数が少なすぎると、経糸及び緯糸に毛羽が生じやすくなり、製織性が低下する。経糸及び緯糸は、染料又は顔料によって着色されていてもよいし、着色されていなくてもよい。特に、経糸及び緯糸が異色に着色されていると、織物柄が鮮明となるので好ましい。 The warp and weft are made by applying a sweet twist to a multifilament yarn. The reason for applying sweet twist is that by sweetening the twist, the width of the warp and weft becomes easier to widen when integrated with cement or resin, the woven fabric itself is smoothed, and the woven fabric is clogged with warp. And the eyes between the wefts disappear. The number of twists of the sweet twist is generally about 60 to 120 T / M, and particularly preferably 50 to 70 T / M. If the number of twists is too large, it becomes difficult to widen the width of the warp and weft when integrated with cement or resin. Further, if the number of twists is too small, fluff is likely to occur in the warp and weft, and the weavability is deteriorated. The warp and weft may or may not be colored with a dye or pigment. In particular, it is preferable that the warp and weft are colored differently because the woven pattern becomes clear.
経糸及び緯糸を用いて織物を製織する方法について説明する。経糸は、複数本の経糸列Ａ群と、経糸列Ａ群に隣り合う複数本の経糸列Ｂ群に分割する。図１及び図２に基づいて具体的に説明すると、経糸Ａ１と経糸Ａ２とが２本の経糸列Ａ群となり、経糸Ｂ１と経糸Ｂ２とが２本の経糸列Ｂ群となり、経糸列Ａ群と経糸列Ｂ群とが隣り合うように分割されている。図１及び図２では、経糸列Ａ群及びＢ群はいずれも２本の経糸よりなるものであるが、この本数は３本であっても４本以上であってもよい。また、経糸列Ａ群及びＢ群を構成する経糸の本数は、同じであっても異なっていてもよい。経糸列Ａ群及びＢ群の本数を２本以上としたのは、経糸の幅を大きく広げることにより、織物の目を消失させて織物柄を鮮明に表現するためである。 A method of weaving a woven fabric using warp threads and weft threads will be described. The warp is divided into a plurality of warp rows A and a plurality of warp rows B adjacent to the warp row A group. More specifically with reference to FIGS. 1 and 2, the warp A1 and the warp A2 form two warp rows A, the warp B1 and the warp B2 form two warp rows B, and the warp row A group. And the warp row B group are divided so as to be adjacent to each other. In FIGS. 1 and 2, both the warp trains A and B are composed of two warp yarns, and the number of warp yarns may be three or four or more. Further, the number of warp yarns constituting the warp yarn rows A group and B group may be the same or different. The number of warp rows A and B is set to two or more in order to greatly widen the width of the warp to eliminate the eyes of the woven fabric and clearly express the woven pattern.
経糸列Ａ群とＢ群を分割するには、織機に設けられている二つの綜絖のうち、一方の綜絖目に経糸Ａ１及びＡ２を通し、その両隣りは経糸を通さずに他方の綜絖目に経糸Ｂ１及びＢ２を通し、これを繰り返せばよい。そして、綜絖を上下に移動させて、経糸列Ａ群を上に移動させたときは経糸列Ｂ群を下に移動させ、経糸列Ａ群を下に移動させたときは経糸列Ｂ群を上に移動させる。これにより、経糸列Ａ群と経糸列Ｂ群の間には、上下方向に隙間が生じる。そして、この隙間に、緯糸Ｃ１を打ち込み、続いて緯糸Ｃ２を打ち込む。図１及び図２では、緯糸を２回打ち込んだ例を示したが、３回又は４回以上打ち込んでもよい。経糸列Ａ群とＢ群の間に生じた隙間に、緯糸を２回以上打ち込むのも、緯糸の幅を大きく広げることにより、織物の目を消失させて織物柄を鮮明に表現するためである。 To divide the warp rows A and B, of the two healds provided on the loom, pass the warp A1 and A2 through one heddle, and pass the warp A1 and A2 through the heddle, and pass the warp A1 and A2 on both sides of the heddle without passing the warp. The warp threads B1 and B2 may be passed through the thread, and this may be repeated. Then, when the heddle is moved up and down and the warp row A group is moved up, the warp row B group is moved down, and when the warp row A group is moved down, the warp row B group is moved up. Move to. As a result, a gap is created in the vertical direction between the warp row A group and the warp row B group. Then, the weft C1 is driven into this gap, and then the weft C2 is driven. Although FIGS. 1 and 2 show an example in which the weft is driven twice, it may be driven three times or four times or more. The reason why the weft is driven twice or more into the gap formed between the warp rows A and B is that the width of the weft is widened so that the stitches of the woven fabric disappear and the woven pattern is clearly expressed. ..
本発明に係る方法で得られたメッシュ織物は、たとえば、セメント本体表面に張設した後、表面塗装用セメントを塗工し、加圧することにより、セメント本体と一体化させてセメント製品を得ることができる。また、メッシュ織物と樹脂フィルムを積層し、加熱加圧して、メッシュ織物の芯鞘型複合繊維の鞘成分を軟化又は溶融させると共に、樹脂フィルムを軟化又は溶融させることにより、両者を一体化させた樹脂製品を得ることができる。さらに、金型にメッシュ織物を配しておき、この金型中に高温の溶融樹脂を圧入することにより、メッシュ織物と溶融樹脂とを接合させた後に固化させて、両者を一体化して樹脂製品を得ることもできる。また、メッシュ織物単体で成型することも可能である。すなわち、メッシュ織物で任意の三次元形態を作成し、これに加熱及び加圧を施し、芯鞘型複合繊維中の鞘成分のみを軟化又は溶融させて、経糸及び緯糸を融着固定させると共に、メッシュ織物の目を詰めて、メッシュ織物単体の成型品を得ることもできる。 The mesh woven fabric obtained by the method according to the present invention is, for example, stretched on the surface of a cement body, coated with cement for surface coating, and pressurized to be integrated with the cement body to obtain a cement product. Can be done. Further, the mesh woven fabric and the resin film were laminated and heated and pressed to soften or melt the sheath component of the core-sheath type composite fiber of the mesh woven fabric, and the resin film was softened or melted to integrate the two. Resin products can be obtained. Further, a mesh woven fabric is arranged in a mold, and a high-temperature molten resin is press-fitted into the mold to join the mesh woven fabric and the molten resin and then solidify them to integrate the two into a resin product. You can also get. It is also possible to mold the mesh fabric alone. That is, an arbitrary three-dimensional form is created from a mesh woven fabric, and heat and pressure are applied to the mesh woven fabric to soften or melt only the sheath component in the core-sheath type composite fiber to fuse and fix the warp and weft. It is also possible to obtain a molded product of the mesh woven fabric by closing the eyes of the mesh woven fabric.
本発明に係る方法で得られたメッシュ織物を用いてセメント製品や樹脂製品を成型すると、メッシュ織物は、甘撚されたマルチフィラメント糸よりなる経糸及び緯糸が特定の態様で配置されているので、加圧時に経糸及び緯糸の幅が大きく拡がり、織物が平滑になると共に織物の目が詰まって消失する。たとえば、図１に示すメッシュ織物を用いた場合には、図３に示す如き状態となり、図２に示すメッシュ織物の場合は、図４に示す如き状態となる。したがって、本発明に係る方法で得られたセメント製品や樹脂製品は、表面が平滑であると共に鮮明な織物柄が表現でき、美装感に優れたものとなる。また、セメント製品や樹脂製品をメッシュ織物で強化しうるので、セメントや樹脂の使用量を少なくしても、良好な機械的強度を持つ製品が得られる。したがって、セメント製品や樹脂製品を軽量化しうるという効果も奏する。 When a cement product or a resin product is molded using the mesh woven fabric obtained by the method according to the present invention, the mesh woven fabric has warp yarns and weft yarns made of sweet-twisted multifilament yarns arranged in a specific manner. When pressure is applied, the widths of the warp and weft threads are greatly expanded, the woven fabric becomes smooth, and the woven fabric is clogged and disappears. For example, when the mesh woven fabric shown in FIG. 1 is used, the state is as shown in FIG. 3, and in the case of the mesh woven fabric shown in FIG. 2, the state is as shown in FIG. Therefore, the cement product and the resin product obtained by the method according to the present invention have a smooth surface and can express a clear woven pattern, and have an excellent aesthetic appearance. Further, since the cement product and the resin product can be reinforced with the mesh woven fabric, a product having good mechanical strength can be obtained even if the amount of the cement and the resin used is reduced. Therefore, it also has the effect of reducing the weight of cement products and resin products.
