Description
本発明は、所望の色合いを実現しうる繊維製品の製造方法に関するものである。 The present invention relates to a method for manufacturing textile products that can achieve the desired color tone.
従来より、糸、組紐、織物又は編物等の繊維製品を販売する場合、需要者の希望する色合いを持つ繊維製品を数点乃至数十点準備するのが一般的である。しかるに、人間が普通に認識しうる色の数は数百乃至数千と言われており、数点乃至数十点の色合いを持つ繊維製品を準備しただけでは、需要者の希望に沿えないということがあった。需要者の希望に沿うためには、染料や顔料等の原料を変更し、繊維自体の製造からやり直さなければならなかった。 Traditionally, when selling textile products such as threads, braids, woven fabrics, or knitted fabrics, it has been common to prepare several to several dozens of textile products with the color shades desired by consumers. However, it is said that the number of colors that humans can normally recognize is several hundred to several thousand, and there have been cases where consumers' wishes could not be met by simply preparing textile products with several to several dozens of colors. In order to meet consumers' wishes, it has been necessary to change the raw materials such as dyes and pigments and start over from the manufacturing of the fibers themselves.
需要者の希望に沿う色合いを実現するために、染色性の異なる二種のマルチフィラメント糸で編成した杢調靴下が提案されている（特許文献１）。かかる杢調靴下は、編成後に需要者が希望する色合いとなるように、染め分けることができ（特許文献、段落００１０）、繊維自体の製造からやり直さなければならないという欠点を回避することができる。しかしながら、かかる方法は杢調の繊維製品を得る場合しか通用せず、概ね単一色の色合いを持つ繊維製品には適用できないものであった。 In order to achieve a color that meets the consumer's desires, heathered socks knitted with two types of multifilament yarn with different dyeability have been proposed (Patent Document 1). Such heathered socks can be dyed differently after knitting to achieve the color desired by the consumer (Patent Document, paragraph 0010), which avoids the drawback of having to start over from the manufacturing of the fibers themselves. However, this method is only applicable when obtaining heathered textile products, and is generally not applicable to textile products with a single color shade.
本発明の課題は、予め準備された複数色のマルチフィラメント糸を用いて、概ね単一色と視認しうる繊維製品を製造する方法を提供するものである。 The objective of the present invention is to provide a method for producing a textile product that can be visually recognized as being substantially a single color using pre-prepared multifilament yarns of multiple colors.
本発明は、特定の芯鞘型複合フィラメントを用いることにより、上記課題を解決したものである。すなわち、本発明は、着色された高融点重合体成分で構成された第一芯成分と、透明又は半透明の低融点重合体成分で構成された鞘成分とよりなる芯鞘型第一複合フィラメントが、複数本集束されてなる第一マルチフィラメント糸を準備する工程、前記第一芯成分とは異なる色の高融点重合体成分で構成された第二芯成分と、透明又は半透明の低融点重合体成分で構成された鞘成分とよりなる芯鞘型第二複合フィラメントが、複数本集束されてなる第二マルチフィラメント糸を準備する工程、前記第一マルチフィラメント糸と前記第二マルチフィラメント糸とを、螺旋状に撚り合わせて糸条を得る工程及び前記糸条に加熱処理を施す工程とよりなり、前記加熱処理により、前記糸条中の前記芯鞘型第一複合フィラメント及び前記芯鞘型第二複合フィラメントを構成している低融点重合体成分を溶融又は軟化させることにより、前記芯鞘型第一複合フィラメントと前記芯鞘型第二複合フィラメントを一体化させることを特徴とする繊維製品の製造方法に関するものである。 The present invention solves the above problem by using a specific core-sheath type composite filament. That is, the present invention relates to a method for producing a textile product, which comprises the steps of: preparing a first multifilament yarn in which a plurality of first core-sheath type composite filaments each composed of a first core component composed of a colored high melting point polymer component and a sheath component composed of a transparent or semitransparent low melting point polymer component are bundled; preparing a second multifilament yarn in which a plurality of second core-sheath type composite filaments each composed of a second core component composed of a high melting point polymer component of a different color from the first core component and a sheath component composed of a transparent or semitransparent low melting point polymer component are bundled; twisting the first multifilament yarn and the second multifilament yarn in a spiral shape to obtain a yarn; and subjecting the yarn to a heat treatment, wherein the heat treatment melts or softens the low melting point polymer component constituting the first core-sheath type composite filament and the second core-sheath type composite filament in the yarn, thereby integrating the first core-sheath type composite filament and the second core-sheath type composite filament.
本発明では、まず第一マルチフィラメント糸を準備する。第一マルチフィラメント糸は、芯鞘型第一複合フィラメントが複数本集束されてなるものである。芯鞘型は同心芯鞘型であっても偏心芯鞘型であってもよい。集束される本数は任意であり、たとえば、２～２００本程度である。また、複数本の集束の状態は、単に芯鞘型第一複合フィラメントが引き揃えられた状態であってもよいし、加撚されて撚りが掛かった状態であってもよい。芯鞘型第一複合フィラメントは、芯成分が高融点重合体成分で鞘成分が低融点重合体成分で形成されてなるものである。芯成分と鞘成分の質量比は任意であるが、芯成分：鞘成分＝１～４：１であるのが好ましい。芯鞘型第一複合フィラメントの繊度も任意であり、たとえば、１～２０デシテックス程度である。高融点重合体成分／低融点重合体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／共重合ポリエステル、ポリエチレンテレフタレート／ポリオレフィン、ナイロン６／ナイロン６６等の組み合わせが用いられる。高融点重合体成分には、顔料又は染料が添加されており、任意の色合いに着色されている。顔料又は染料としては、従来公知のものが用いられる。低融点重合体成分は、光が透過するように透明又は半透明となっている。低融点重合体成分を透明にするには、顔料を添加しなければよい。また、半透明にするには、顔料の添加量を少なくすればよい。したがって、第一マルチフィラメント糸は、着色された高融点重合体成分の色合いとして視認される。 In the present invention, first, a first multifilament yarn is prepared. The first multifilament yarn is formed by bundling a plurality of sheath-core first composite filaments. The sheath-core type may be a concentric sheath-core type or an eccentric sheath-core type. The number of bundled filaments is arbitrary, for example, about 2 to 200. The bundled state of the plurality of filaments may be a state in which the sheath-core first composite filaments are simply aligned, or may be a state in which they are twisted. The sheath-core first composite filament is formed by a core component made of a high melting point polymer component and a sheath component made of a low melting point polymer component. The mass ratio of the core component to the sheath component is arbitrary, but it is preferable that the core component:sheath component = 1 to 4:1. The fineness of the sheath-core first composite filament is also arbitrary, for example, about 1 to 20 decitex. As a combination of a high melting point polymer component/a low melting point polymer component, a combination of polyethylene terephthalate/copolymerized polyester, polyethylene terephthalate/polyolefin, nylon 6/nylon 66, etc. is used. A pigment or dye is added to the high melting point polymer component, and the high melting point polymer component is colored in any color. Conventionally known pigments or dyes are used. The low melting point polymer component is transparent or translucent so that light can pass through. To make the low melting point polymer component transparent, no pigment should be added. To make it translucent, the amount of pigment added should be reduced. Therefore, the first multifilament yarn is visually recognized as the color of the colored high melting point polymer component.
次に、第二マルチフィラメント糸を準備する。第二マルチフィラメント糸も第一マルチフィラメント糸と同様の構成となっているが、異なる点は、高融点重合体成分の色合いが、第一マルチフィラメント糸と異なる色合いになっている点である。すなわち、第一マルチフィラメント糸中の高融点重合体成分と第二マルチフィラメント糸中の高融点重合体成分とは、異色となっている。たとえば、第一マルチフィラメント糸中の高融点重合体成分が橙色に着色されている場合には、第二マルチフィラメント糸中の高融点重合体成分は橙色とは異なる色合い、たとえば、緑色や白色に着色されている。したがって、第二マルチフィラメント糸は、第一マルチフィラメント糸の色合いとは、異なった色合いのものとして視認される。なお、本発明で言う着色とか色合いには、白色，灰色及び黒色の無彩色も含む。 Next, a second multifilament yarn is prepared. The second multifilament yarn has the same structure as the first multifilament yarn, but the difference is that the color of the high melting point polymer component is different from that of the first multifilament yarn. That is, the high melting point polymer component in the first multifilament yarn and the high melting point polymer component in the second multifilament yarn are different colors. For example, if the high melting point polymer component in the first multifilament yarn is colored orange, the high melting point polymer component in the second multifilament yarn is colored a color different from orange, for example, green or white. Therefore, the second multifilament yarn is visually recognized as having a different color from that of the first multifilament yarn. Note that the coloring and coloring referred to in this invention also include achromatic colors such as white, gray, and black.
準備した第一マルチフィラメント糸と第二マルチフィラメント糸とを引き揃えた後、加撚して撚り合わせることにより、糸条を得る。この加撚により、第一マルチフィラメント糸中の芯鞘型第一複合フィラメント及び第二マルチフィラメント糸中の芯鞘型第二複合フィラメントは、各々螺旋状に撚り合わされることになる。この糸条は、第一マルチフィラメント糸と第二マルチフィラメント糸が異色となっているので、各色を視認でき、いわゆる杢調となっている。 The prepared first multifilament yarn and second multifilament yarn are aligned and then twisted together to obtain a yarn. This twisting causes the core-sheath first composite filament in the first multifilament yarn and the core-sheath second composite filament in the second multifilament yarn to be twisted together in a spiral shape. As the first multifilament yarn and the second multifilament yarn are of different colors, the colors of the yarn can be visually recognized, resulting in a so-called mottled look.
次に、糸条に加熱処理を施す。この加熱処理は、第一マルチフィラメント糸中の低融点重合体成分のみ及び第二マルチフィラメント糸中の低融点重合体成分のみを、軟化又は溶融させて一体化するための処理である。したがって、加熱温度は、両低融点重合体成分の軟化温度以上又は融点以上であり、両高融点重合体成分の融点未満の温度で処理される。加熱処理は、糸条を緊張状態にして行うのが好ましい。糸条を緊張状態にしておくと、両低融点重合体成分が流動しやすくなり、一体化しやすいためである。この加熱処理により、繊維形態を維持し螺旋状となっている第一芯成分群及び第二芯成分群が、一体化した両低融点重合体成分よりなる母体中に存在することになる。このため、透明又は半透明の母体中に、異色の第一芯成分群と第二芯成分群とが螺旋状で混在し、通常の目視状態においては、両者の色を混色した概ね単一色として視認されるのである。 Next, the yarn is subjected to a heat treatment. This heat treatment is a treatment for softening or melting only the low melting point polymer component in the first multifilament yarn and only the low melting point polymer component in the second multifilament yarn to integrate them. Therefore, the heating temperature is at or above the softening temperature or melting point of both low melting point polymer components and below the melting point of both high melting point polymer components. The heat treatment is preferably performed with the yarn in a tensed state. This is because keeping the yarn in a tensed state makes both low melting point polymer components easier to flow and integrate. This heat treatment causes the first core component group and the second core component group, which maintain their fiber form and are spirally shaped, to exist in a matrix made of both integrated low melting point polymer components. Therefore, the first core component group and the second core component group, which are different colors, are mixed in a spiral shape in a transparent or translucent matrix, and are visually recognized as a roughly single color in which the colors of both are mixed under normal visual conditions.
糸条に対する加熱処理は、糸条を編組又は編織して、組紐、織物又は編物とした後で行ってもよい。この場合、組紐、織物又は編物等の繊維製品中の糸条は、概ね単一色として視認され、繊維製品全体も概ね単一色として視認されるものである。 The heat treatment of the yarn may be carried out after the yarn has been braided or woven into a braided cord, woven fabric, or knitted fabric. In this case, the yarn in the textile product such as the braided cord, woven fabric, or knitted fabric will be visually recognized as being of roughly a single color, and the entire textile product will also be visually recognized as being of roughly a single color.
本発明に係る方法で得られる繊維製品は、低融点重合体成分が軟化又は溶融して一体化しているので、比較的剛直である。したがって、靴の甲被、安全ネット、ブラインド地等の用途に好適に使用しうるものである。 The textile products obtained by the method of the present invention are relatively rigid because the low melting point polymer components are softened or melted and integrated. Therefore, they can be suitably used for applications such as shoe uppers, safety nets, and blinds.
本発明に係る繊維製品の製造方法は、複数色の特定の芯鞘型複合フィラメントを特定の方法で組み合わせて処理することにより、任意の概ね単一色を持つ繊維製品を得ることができる。したがって、需要者の希望に沿う色合いを持つ繊維製品を、合理的に提供しうるという効果を奏する。 The method for manufacturing textile products according to the present invention can obtain textile products of any generally single color by combining and processing specific core-sheath composite filaments of multiple colors in a specific manner. This has the effect of being able to rationally provide textile products with colors that meet the consumer's desires.
