Description
本発明は、色に所望の濃淡を付与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 impart desired shades of color.
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に関し、濃淡を持つ数点の繊維製品を準備するのが一般的である。しかるに、需要者の希望に沿うためには、染料や顔料等の原料又は配合量を変更し、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 textile products with different shades of the color desired by the consumer. However, in order to meet the consumer's wishes, it has been necessary to change the raw materials or blend amounts of dyes, pigments, etc., and start over from the manufacturing of the fibers themselves.
たとえば、特許文献１には、芯鞘型複合繊維において芯成分と鞘成分とで濃淡の異なる色に着色し、芯成分と鞘成分の質量比を変更することで、色の濃淡を持つマルチフィラメント糸を製造することが記載されている。しかしながら、この方法においても、芯鞘型複合繊維の製造自体からやり直さなければならないという欠点があった。 For example, Patent Document 1 describes the production of multifilament yarns with different shades of color by coloring the core and sheath components of a core-sheath composite fiber in different shades and changing the mass ratio of the core and sheath components. However, even this method has the disadvantage that the production of the core-sheath composite fiber itself must be started over.
本発明の課題は、色の濃淡を変更した繊維製品を合理的に得られる方法を提供することにある。 The objective of the present invention is to provide a method for rationally obtaining textile products with varying color shades.
本発明は、予め準備された所定の色を持つマルチフィラメント糸と、予め準備された透明又は半透明のマルチフィラメント糸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、無色透明又は無色半透明の低融点重合体成分で構成された第一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、無色透明又は無色半透明の高融点重合体成分で構成された第二芯成分と、無色透明又は無色半透明の低融点重合体成分で構成された第二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 pre-prepared multifilament yarn of a predetermined color and a pre-prepared transparent or translucent multifilament yarn. That is, the present invention relates to a method for producing a textile product, comprising the steps of: preparing a first multifilament yarn in which a plurality of sheath-core first composite filaments are bundled; the first composite filaments each having a first core component made of a colored high-melting-point polymer component and a first sheath component made of a colorless, transparent, or colorless, translucent, low-melting-point polymer component; preparing a second multifilament yarn in which a plurality of sheath-core second composite filaments each having a second core component made of a colorless, transparent, or colorless, translucent, high-melting-point polymer component and a second sheath component made of a colorless, transparent, or colorless, translucent, low-melting-point polymer component; twisting the first multifilament yarn and the second multifilament yarn together in a spiral 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 sheath-core first composite filaments and the sheath-core second composite filaments in the yarn, thereby integrating the sheath-core first composite filaments and the sheath-core second composite filaments.
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、第一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。第一芯成分と第一鞘成分の質量比は任意であるが、第一芯成分：第一鞘成分＝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無色透明又は無色半透明となっている。低融点重合体成分を無色透明又は無色半透明にするには、顔料を添加しなければよい。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として視認される。 In the present invention, a first multifilament yarn is first prepared. The first multifilament yarn is composed of a plurality of sheath-core first composite filaments bundled together. The sheath-core type may be concentric or eccentric. The number of bundled filaments is arbitrary, for example, approximately 2 to 200. Furthermore, the bundled state of the plurality of filaments may be a state in which the sheath-core first composite filaments are simply pulled together, or may be a twisted state. The sheath-core first composite filament is composed of a first 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 first core component to the first sheath component is arbitrary, but a first core component:first sheath component ratio of 1 to 4:1 is preferable. The fineness of the sheath-core first composite filament is also arbitrary, for example, approximately 1 to 20 decitex. Examples of combinations of high-melting-point polymer component/low-melting-point polymer component include polyethylene terephthalate/copolyester, polyethylene terephthalate/polyolefin, and nylon 6/nylon 66. A pigment or dye is added to the high-melting point polymer component, and the component is colored in any desired color. Conventional pigments or dyes can be used. The low-melting point polymer component is colorless, transparent, or colorless, translucent, allowing light to pass through. The low-melting point polymer component can be made colorless, transparent, or colorless, translucent by not adding a pigment. 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、色のない無色透明又は無色半透明となっている点である。すなわち、第二マルチフィラメント糸を構成する芯鞘型第二複合フィラメントは、第二芯成分が無色透明又は無色半透明の高融点重合体成分で形成されており、第二鞘成分が無色透明又は無色半透明の低融点重合体成分で形成されている。なお、本発明で言う着色とか色には、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 differs in that it is colorless, transparent, or colorless translucent. That is, the core-sheath second composite filament that constitutes the second multifilament yarn has a second core component formed from a colorless, transparent, or colorless translucent high-melting-point polymer component, and a second sheath component formed from a colorless, transparent, or colorless translucent low-melting-point polymer component. Note that, in the present invention, the terms "colored" and "colored" 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が色を持ち、第二マルチフィラメント糸が無色透明又は無色半透明となっている。したがって、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の質量比を変更することよって、種々の濃淡を持つ糸条を得ることができる。なお、加熱処理前の糸条の段階では、無色透明又は無色半透明の第二マルチフィラメント糸が、着色された第一マルチフィラメント糸と混在しているため、光を透過できず光の反射によって白色と視認され、この糸条はいわゆる杢調を呈する。 The prepared first multifilament yarn and second multifilament yarn are aligned and then twisted together to obtain a yarn. This twisting causes the sheath-core first composite filaments in the first multifilament yarn and the sheath-core second composite filaments in the second multifilament yarn to be twisted together in a spiral pattern. In this yarn, the first multifilament yarn is colored, and the second multifilament yarn is colorless, transparent, or colorless, translucent. Therefore, by changing the mass ratio of the first multifilament yarn to the second multifilament yarn, yarns with various shades can be obtained. Furthermore, at the yarn stage before heat treatment, the colorless, transparent, or colorless, translucent second multifilament yarn is mixed with the colored first multifilament yarn, preventing light from passing through and appearing white due to light reflection, giving the yarn a so-called mottled appearance.
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、無色透明又は無色半透明の母体中に、色を持つ第一芯成分群と色を持たない第二芯成分群とが螺旋状で混在した状態になる。したがって、加熱処理した糸条は、第二マルチフィラメント糸が独立して存在しないため、通常の目視状態において、杢調とならず、第一芯成分群の色を薄めた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 intended to soften or melt 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, thereby integrating them. Therefore, the heating temperature is above the softening temperature or melting point of both low-melting-point polymer components, but below the melting points of both high-melting-point polymer components. The heat treatment is preferably performed while the yarn is under tension. This is because keeping the yarn under tension facilitates the flow of both low-melting-point polymer components, facilitating integration. This heat treatment results in the first core component group and second core component group, which maintain their fiber form and are spirally shaped, being present in a matrix composed of the integrated low-melting-point polymer components. As a result, the colored first core component group and the colorless second core component group are mixed in a spiral shape within a colorless, transparent, or colorless, translucent matrix. Therefore, since the heat-treated yarn does not have an independent second multifilament yarn, under normal visual conditions it does not appear mottled, but appears to be a diluted color of the first core component group.
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、第一芯成分の色を薄めた色として視認され、繊維製品全体も第一芯成分の色を薄めた色として視認されるのである。 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 perceived as a diluted color of the first core component, and the entire textile product will also be visually perceived as a diluted color of the first core component.
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 component is softened or melted and integrated. Therefore, they are suitable for use in shoe uppers, safety nets, blinds, and other applications.
本発明に係る繊維製品の製造方法は、色を持つ特定の第一マルチフィラメント糸と色を持たない透明又は半透明の特定の第二マルチフィラメント糸を、質量比を変更して組み合わせて処理することにより、種々の色の濃淡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の濃淡を持つ繊維製品を、合理的に提供しうるという効果を奏する。 The textile product manufacturing method of the present invention can produce textile products with a variety of color shades by combining and processing a specific colored first multifilament yarn and a specific colorless transparent or translucent second multifilament yarn at varying mass ratios. This has the effect of enabling the rational provision of textile products with color shades that meet the consumer's needs.

一方、第二芯成分がポリエチレンテレフタレート（融点２６０℃）よりなる無色半透明の芯成分と、共重合ポリエステル（融点１６１℃）よりなる無色半透明の鞘成分とよりなる芯鞘型第二複合フィラメントを、４８本集束して、２８０デシテックス／４８フィラメントの第二マルチフィラメント糸を準備した。
なお、芯鞘型第一複合フィラメント及び芯鞘型第二複合フィラメントの芯成分と鞘成分の質量比は、芯成分：鞘成分＝２．７：１である。
Example 1
A first multifilament yarn of 280 decitex/48 filaments was prepared by bundling 48 core-sheath first composite filaments, each of which had a black core component made of polyethylene terephthalate (melting point 260°C) mixed with a black pigment and a colorless, translucent sheath component made of copolymer polyester (melting point 161°C).
Meanwhile, 48 core-sheath type second composite filaments, each consisting of a colorless, translucent core component made of polyethylene terephthalate (melting point 260°C) and a colorless, translucent sheath component made of copolymer polyester (melting point 161°C), were bundled together to prepare a second multifilament yarn of 280 decitex/48 filaments.
The mass ratio of the core component to the sheath component of the first core-sheath type composite filament and the second core-sheath type composite filament was core component:sheath component=2.7:1.
第一マルチフィラメント糸１本と第二マルチフィラメント糸１本とを引き揃えた後、共立機械製リング撚糸機ＳＴ－３０に掛けて、８００回／ｍの撚り数でＳ撚りを施し下撚糸を得た。下撚糸２本を引き揃え、共立機械製リング撚糸機ＳＴ－３０に掛けて、６００回／ｍの撚り数でＺ撚りを上撚りを施して、杢調の諸撚り糸条を得た。 One first multifilament yarn and one second multifilament yarn were aligned, then passed through a Kyoritsu Kikai ST-30 ring twister and subjected to an S twist at a twist rate of 800 turns/m to obtain a first-twisted yarn. Two first-twisted yarns were aligned, then passed through a Kyoritsu Kikai ST-30 ring twister and subjected to a Z twist at a twist rate of 600 turns/m to obtain a flecked plied yarn.
得られた杢調の諸撚り糸条を用いて、８打角打ち製紐機を使用し、８本角打ち組紐を得た。組紐（長さ約４０ｃｍ）の両端を固定した状態で、１８０℃の耐熱オーブンにて２分間熱処理を行い、灰色の組紐を得た。 The resulting mottled plied yarn was used to produce an eight-strand braided cord using an eight-strand braiding machine. With both ends of the braid (approximately 40 cm long) fixed, it was heat-treated in a heat-resistant oven at 180°C for two minutes to produce a gray braided cord.
