Description
本発明は、繊細な霜降り色調を有する異染性複合マルチフィラメント糸、それを用いた織編物および織編物の製造方法に関する。 The present invention relates to a metachromatic composite multifilament yarn having a delicate marbling color tone, a woven or knitted fabric using the same, and a method for producing the woven or knitted fabric.
従来から異染性を有する繊維群を組み合わせ、片染めによる霜降り調の色調を表現する手段が試みられてきており、分散染料可染性のポリエステル繊維と分散染料不染性の天然繊維や再生繊維のレーヨン繊維などとの組み合わせによる複合糸などが、公知の技術として知られている。 Conventionally, attempts have been made to combine a group of fibers having different dyeing properties to express a marbling tone color by single dyeing, and disperse dye-dyeable polyester fibers and disperse dye-undyed natural fibers and recycled fibers. Composite yarns in combination with other rayon fibers are known as a known technique.
特許文献１には、アセテート繊維マルチフィラメントをアルカリ処理すると脱アセチル反応により減量されることを利用して、セルローストリアセテート繊維とセルロースジアセテート繊維を組み合わせて複合糸とした後、セルロースジアセテート繊維の内層を鹸化させずに表層を鹸化処理することで直接染料や反応染料等の片染めを可能とする方法が記載されている。 In Patent Document 1, by utilizing the fact that the acetate fiber multifilament is reduced by deacetylation when it is treated with alkali, a cellulose triacetate fiber and a cellulose diacetate fiber are combined into a composite yarn, and then the inner layer of the cellulose diacetate fiber is used. A method is described in which saponification of the surface layer without saponification of the dye enables direct dyeing of reactive dyes or dyes.
さらには、特許文献２には、アセテート繊維の最内層に至るまで鹸化する方法が記載されており、この場合、分散染料での染色によっても片染めの効果が得られることは容易に推察できる。
しかし再生繊維のレーヨン繊維などとの組み合わせによる複合マルチフィラメント糸などの場合、繊度は工業生産での製造安定性や製造コストの面から細繊度品種に限度があり、繊度が２５デシテックス未満の再生繊維は容易に得られず、然るに天然繊維を含めて細繊度品種のセルロース系繊維から得られる異染性複合マルチフィラメント糸の色調は知られていなかった。 However, in the case of composite multifilament yarns, etc., in combination with regenerated fibers such as rayon fibers, the fineness is limited in terms of fineness varieties in terms of manufacturing stability and cost in industrial production, and regenerated fibers with a fineness of less than 25 dtex. However, the color tone of the metachromatic multi-filament yarn obtained from cellulosic fibers of fine fineness including natural fibers was not known.
特に薄地衣料などでは用いる複合マルチフィラメント糸自体の繊度が小さく、複合マルチフィラメント糸に占める両成分の繊度比を大きくできないため、得られる布帛は分散染料不染成分による無着色部が多く見える色調のものとなり、繊細な霜降り色調を有するものは得られなかった。 Especially for thin lichens, the fineness of the composite multifilament yarn itself is small and the fineness ratio of both components in the composite multifilament yarn cannot be increased. Therefore, the resulting fabric has a color tone in which many uncolored parts due to disperse dye-dye-free components can be seen. A product having a delicate marbling color tone was not obtained.
特許文献１の方法では、アセテート繊維マルチフィラメントの芯部が鹸化されていないため、分散染料にて染色され、十分な無着色効果が得られず、霜降り調とならない。 In the method of Patent Document 1, since the core portion of the acetate fiber multifilament is not saponified, it is dyed with a disperse dye, a sufficient non-coloring effect cannot be obtained, and a marbling tone is not obtained.
また特許文献２の方法では、アルカリ処理後の繊度が大きく、分散染料にて染色した布帛は無着色部が過度に多い色調であり、微細な無着色部を有する霜降り色調のものは得られていなかった。 Further, in the method of Patent Document 2, the fineness after alkali treatment is large, and the fabric dyed with disperse dye has a color tone with excessively uncolored portions, and a marbled color tone with fine uncolored portions has been obtained. There wasn't.
本発明はこのような従来技術における問題点を解決するものであり、微細な異染色部あるいは無着色部を有する異染性複合マルチフィラメント糸及びその織編物を提供するものである。 The present invention solves such problems in the prior art, and provides a multicolored composite multifilament yarn having a fine dyed portion or a non-colored portion and a woven or knitted fabric thereof.

本発明は、繊細な霜降り色調を有する異染性複合マルチフィラメント糸および織編物が得られる。 According to the present invention, a metachromatic composite multifilament yarn and a knitted or knitted fabric having a delicate marbling color tone can be obtained.
本発明の異染性複合マルチフィラメント糸は、セルロース系繊維マルチフィラメントと、前記セルロース系繊維マルチフィラメントとは染色性を異にする長繊維マルチフィラメントとからなる複合マルチフィラメント糸であるが、セルロース系繊維マルチフィラメントの繊度が５デシテックス以上、２５デシテックス未満で、かつセルロース系繊維マルチフィラメントの混率が５質量％以上３０質量％以下であることが必要である。 The metachromatic composite multifilament yarn of the present invention is a composite multifilament yarn comprising a cellulosic fiber multifilament and a long fiber multifilament having a different dyeability from the cellulosic fiber multifilament. It is necessary that the fineness of the fiber multifilament is 5 dtex or more and less than 25 dtex, and the mixing ratio of the cellulosic fiber multifilament is 5% by mass or more and 30% by mass or less.
セルロース系繊維マルチフィラメントの繊度が２５デシテックス未満であると、分散染料による片染めにて得られる布帛はセルロース系繊維マルチフィラメントによる無着色部が細かく分散した繊細な色調のものが得られる。一方、セルロース系繊維マルチフィラメントの繊度が５デシテックス以上の場合、無着色部が明確に識別でき、霜降り調としての効果が得られる。 When the fineness of the cellulosic fiber multifilament is less than 25 dtex, a fabric obtained by one-dying with a disperse dye can have a delicate color tone in which the non-colored portions of the cellulosic fiber multifilament are finely dispersed. On the other hand, when the fineness of the cellulosic fiber multifilament is 5 dtex or more, the uncolored portion can be clearly identified, and an effect as a marbling tone is obtained.
また前記セルロース系繊維マルチフィラメントの混率が５質量％以上であると、分散染料による片染めにて得られる布帛の無着色部が判断でき、霜降り調としての効果が得られる。一方、前記セルロース系繊維マルチフィラメントの混率が３０質量％以下の場合、分散染料による片染めにて得られる布帛はセルロース系繊維マルチフィラメントによる無着色部が細かく分散した繊細な色調のものが得られる。 Further, when the mixing ratio of the cellulose fiber multifilament is 5% by mass or more, an uncolored portion of the fabric obtained by one-dying with a disperse dye can be determined, and an effect as a marbling tone is obtained. On the other hand, when the mixing ratio of the cellulose-based fiber multifilament is 30% by mass or less, a fabric obtained by one-dyeing with a disperse dye can have a delicate color tone in which the non-colored portions of the cellulose-based fiber multifilament are finely dispersed. .
セルロース系繊維マルチフィラメントは、細繊度糸を混繊することも可能であるが、取り扱いが困難で、さらに製造そのものが困難であるため、本発明に用いるセルロース系繊維マルチフィラメントは、アルカリ減量を伴う後加工により得られるものがより好ましい。 Cellulosic fiber multifilaments can be mixed with fine yarns, but they are difficult to handle and difficult to manufacture. Therefore, the cellulose fiber multifilaments used in the present invention involve an alkali weight loss. What is obtained by post-processing is more preferable.
繊度が５デシテックス以上、２５デシテックス未満であるセルロース系繊維マルチフィラメントは、４０デシテックス以下のアセテート繊維マルチフィラメントをアルカリ処理して得ることも可能である。アセテート繊維マルチフィラメントが４０デシテックス以下の繊度の場合、アルカリ処理後の繊度を２５デシテックス未満とするためには減量率を高くする必要がなく、処理条件が広く取れるため好ましい。 Cellulosic fiber multifilaments having a fineness of 5 dtex or more and less than 25 dtex can also be obtained by subjecting acetate fiber multifilaments of 40 dtex or less to an alkali treatment. When the acetate fiber multifilament has a fineness of 40 dtex or less, it is not necessary to increase the weight loss rate in order to make the fineness after the alkali treatment less than 25 dtex, and it is preferable because the treatment conditions can be widely taken.
また、アルカリ処理の方法は限定されるものではないが、好ましいものとしてアセテート系繊維マルチフィラメントの最内層に至るまで鹸化する方法が挙げられる。アセテート系繊維マルチフィラメントの最内層に至るまで鹸化するとは、繊維のアルカリ処理後の減量率において、セルロースジアセテート繊維では、３８質量％程度、セルローストリアセテート繊維では、４２質量％程度まで、鹸化による減量を施すことをいう。 Moreover, the method of alkali treatment is not limited, but a preferable method is saponification to reach the innermost layer of the acetate fiber multifilament. Saponification to the innermost layer of acetate fiber multifilament means that the weight loss after alkali treatment of the fiber is about 38% by mass for cellulose diacetate fiber and about 42% by mass for cellulose triacetate fiber. It means to give.
アルカリ処理は、例えば、水酸化ナトリウム、水酸化カリウム、炭酸カルシウム等のアルカリ化合物を用い、かかるアルカリ化合物の溶液にアセテート系繊維を浸漬、パッデイング等により含浸させて処理する。アルカリ処理における処理液濃度、処理温度、処理時間は、用いるアルカリ化合物により、また目的物により異なるが、好ましいセルロースジアセテート繊維のアルカリ処理条件を挙げるならば、水酸化ナトリウム水溶液を用いた場合、水酸化ナトリウム濃度は５質量％を超えない濃度、処理温度は４０〜８０℃、処理時間は６０分以内であり、減量率で３８質量％を目安に処理する。かかるアルカリ処理により、アセテート系繊維より本発明に用いるセルロース系繊維、および、本発明の複合マルチフィラメント糸または、織編物を得ることができる。 The alkali treatment is performed, for example, by using an alkali compound such as sodium hydroxide, potassium hydroxide, or calcium carbonate, and immersing the acetate fiber in the solution of the alkali compound by impregnation or padding. The treatment solution concentration, treatment temperature, and treatment time in the alkali treatment vary depending on the alkali compound used and the target product. If preferred alkali treatment conditions for cellulose diacetate fibers are given, water is used in the case of using an aqueous sodium hydroxide solution. The concentration of sodium oxide does not exceed 5% by mass, the treatment temperature is 40 to 80 ° C., the treatment time is 60 minutes or less, and the treatment is performed with a weight loss rate of 38% by mass as a guide. By such alkali treatment, the cellulose fiber used in the present invention and the composite multifilament yarn or woven or knitted fabric of the present invention can be obtained from the acetate fiber.
また、セルロース系繊維マルチフィラメントと染色性を異にする長繊維マルチフィラメントは、ポリエステル繊維やナイロンといった直接染料や反応染料に不染性の繊維であれば特に限定されるものではない。さらにはセルロースジアセテート繊維をアルカリ処理によってセルロース系繊維成分とする場合は、染色性を異にする繊維成分としてセルローストリアセテート繊維を用いることも可能である。 The long fiber multifilament having a dyeability different from that of the cellulosic fiber multifilament is not particularly limited as long as it is a fiber that is non-dyeable to a direct dye or a reactive dye such as polyester fiber or nylon. Furthermore, when cellulose diacetate fiber is made into a cellulose fiber component by alkali treatment, cellulose triacetate fiber can be used as a fiber component having different dyeability.
複合マルチフィラメント糸に、撚数Ｔｗ（回／ｍ）；５０００／√Ｄｔｅｘ≦Ｔｗ≦２７０００／√Ｄｔｅｘの範囲で、撚りを施して用いることもできる。 The composite multifilament yarn can also be used after being twisted in the range of twist number Tw (times / m); 5000 / √Dtex ≦ Tw ≦ 27000 / √Dtex.
（但し、Ｄｔｅｘは複合マルチフィラメント糸の総繊度を示すものである。）
撚数Ｔｗ（回／ｍ）が５０００／√Ｄｔｅｘ以上であると、セルロース系繊維マルチフィラメント糸と前記セルロース系マルチフィラメントとは染色性を異にする長繊維マルチフィラメントが適度にこなれて、ナチュラルなビジュアル感を有する繊細な霜降り調の布帛が得られる。一方、撚数Ｔｗ（回／ｍ）が、２７０００／√Ｄｔｅｘ以下であると適度なドレープ性により、優雅なシルエットを有する繊細な霜降り調の布帛が得られる。
(However, Dtex indicates the total fineness of the composite multifilament yarn.)
When the number of twists Tw (times / m) is 5000 / √Dtex or more, the cellulose-based multifilament yarn and the cellulose-based multifilament have moderately long filament multifilaments with different dyeability, and are natural. A delicate marbling-like fabric having a visual feeling can be obtained. On the other hand, if the twist number Tw (times / m) is 27000 / √Dtex or less, a delicate marbling-like fabric having an elegant silhouette can be obtained due to appropriate drape.
また、セルロース系繊維マルチフィラメントとは染色性を異にする長繊維マルチフィラメントは、霜降り調の色調を強調させる目的で、セルロース系繊維マルチフィラメントと混繊する以前にエアー交絡または撚糸を施すことが好ましい。さらにはセルロース系繊維マルチフィラメントとセルロース系繊維マルチフィラメントとは染色性を異にする長繊維マルチフィラメントの複合方法として、引き揃え、合撚、またはエアー交絡を施す方法が考えられるが、特に限定されるものではない。 In addition, long fiber multifilaments that differ in dyeability from cellulosic fiber multifilaments may be air entangled or twisted before being mixed with cellulosic fiber multifilaments for the purpose of enhancing the marbling tone. preferable. Furthermore, as a method of combining long-fiber multifilaments in which cellulosic fiber multifilaments and cellulose-based fiber multifilaments have different dyeability, methods of aligning, twisting, or air entanglement can be considered, but there is a particular limitation. It is not something.
セルロース系繊維マルチフィラメントがアセテート系繊維マルチフィラメントのアルカリ処理糸である場合、アセテート系繊維マルチフィラメントの紡出糸を巻き取る工程において、セルロース系繊維マルチフィラメントとは染色性を異にする長繊維マルチフィラメントを加えて巻き取ることもなんらは問題ない。 When the cellulosic fiber multifilament is an alkali-treated yarn of acetate fiber multifilament, in the process of winding the spun yarn of the acetate fiber multifilament, the long fiber multifilament having a dyeability different from that of the cellulosic fiber multifilament is used. There is no problem with adding a filament and winding it.
本発明の異染性複合マルチフィラメント糸を用いた織編物は、他の繊維と交織・交編または交撚等により複合しても良く、本発明の異染性複合マルチフィラメント糸が布帛において２０質量％以上含まれていることが好ましい。２０質量％以上であると無着色部が識別でき、霜降り調としての効果が得られる。 The knitted or knitted fabric using the metachromatic multifilament yarn of the present invention may be combined with other fibers by knitting, knitting, knitting or the like, and the multicolored multifilament yarn of the present invention is 20 in the fabric. It is preferable that it is contained by mass% or more. An uncolored part can be identified as it is 20 mass% or more, and the effect as a marbling tone is acquired.
