Description
本発明は、トリコットストレッチ編地に関する。 The present invention relates to a tricot stretch knitted fabric.
弾性糸と非弾性糸を用いたトリコット編地は、ストレッチ性に優れることから、スポーツ衣料や下着に広く用いられており、特に、昨今ではスポーツウエア用インナー（アンダーウエアともいう）としても好評である。このスポーツウエア用インナーの素材には、より薄く、軽い、ボディフィット性のよい、快適な着用感のトリコット編地が求められており、各種商品が開発されているが、未だ満足すべきものが得られているとは言えない。 Tricot knitted fabrics using elastic and inelastic yarns are widely used in sports clothing and underwear due to their excellent stretchability. Especially, these are popular as innerwear for sportswear (also called underwear). is there. This sportswear inner material is required to have a tricot knitted fabric that is thinner, lighter, has a good body fit, and is comfortable to wear, and various products have been developed. It cannot be said that it is done.
例えば、ポリウレタン繊維等の弾性糸とナイロンフィラメント糸を用いたトリコット編地は、ナイロンフィラメント糸が湿潤時に膨張する性質があるため、形態安定性に問題が生じ、また風合いにヌメリ感があり、着用感の点でも問題がある。 For example, a tricot knitted fabric using elastic yarn such as polyurethane fiber and nylon filament yarn has the property that the nylon filament yarn expands when wet, which causes problems in form stability, and the texture is slimy and worn. There is also a problem in terms of feeling.
ナイロンフィラメント糸に代え水膨潤性の問題のないポリエステルフィラメント糸を用いて弾性糸と混用したトリコット編地が上市されているが、ポリエステルフィラメント糸の高ヤング率による風合いの硬さが問題となり、また、染色時に分散染料が弾性糸のポリウレタン繊維に多量に染着されるため、洗濯堅牢度や昇華堅牢度が問題となり、さらに、ポリエステルフィラメント糸の染色での温度が１３０℃と高くポリウレタン繊維の劣化を生じる。 Tricot knitted fabric mixed with elastic yarn using polyester filament yarn that does not have a problem of water swelling instead of nylon filament yarn is on the market, but the hardness of the texture due to the high Young's modulus of the polyester filament yarn becomes a problem, Since the disperse dye is dyed in a large amount on the elastic yarn polyurethane fiber at the time of dyeing, the fastness to washing and sublimation fastness becomes a problem, and the polyester filament yarn is dyed at a high temperature of 130 ° C. Produce.
また、堅牢度対策としてカチオン染料可染型のポリエステルフィラメント糸を用いたものもあるが、通常のヤング率、単糸繊度のカチオン染料可染型のポリエステルフィラメント糸を用いたのでは、そのトリコット編地は風合いが硬く、満足のいく商品を得るに至っていない。 In addition, some dye dyeable polyester filament yarns are used as a measure against fastness. However, if a normal dye modulus polyester yarn yarn with a single yarn fineness is used, the tricot The ground is hard and has not yet yielded satisfactory products.

Knitted fabric of finished basis weight of 150~250g / m 2
本発明においては、ポリエステルフィラメント糸を、ヤング率が８５ＣＮ／ｄｔｅｘ以下、単糸繊度が１ｄｔｅｘ以下のポリエステルフィラメント糸とすることにより、絹に近い風合い、肌に刺激の少ないマイルドな肌触りとソフトな風合い、しかも、ポリエステルフィラメント糸を、染色温度が高温ではないカチオン染料可染型ポリエステルフィラメント糸とすることにより、弾性糸と共にトリコット編地としたときに、優れた発色性、染色堅牢性が得られ、本発明によれば、快適な着用感と身体の動きに違和感なく追随するボディフィット性に優れ、発色性と染色堅牢度にも優れたトリコットストレッチ編地が得られる。 In the present invention, the polyester filament yarn is a polyester filament yarn having a Young's modulus of 85 CN / dtex or less and a single yarn fineness of 1 dtex or less, so that it feels close to silk, has a mild touch and soft texture that is less irritating to the skin. Moreover, when the polyester filament yarn is a cationic dye-dyeable polyester filament yarn whose dyeing temperature is not high, when it is made into a tricot knitted fabric together with an elastic yarn, excellent color development and dyeing fastness are obtained. According to the present invention, it is possible to obtain a tricot stretch knitted fabric that is excellent in comfortable wearing feeling and body fit following the movement of the body without a sense of incongruity, and also excellent in color development and dyeing fastness.
本発明において、カチオン染料可染型ポリエステルフィラメント糸は、ヤング率が８５ＣＮ／ｄｔｅｘ以下であることが必要であり、好ましくは、ヤング率７５ＣＮ／ｄｔｅｘ以下である。ヤング率が８５ＣＮ／ｄｔｅｘを超えると、編地に硬さが感じられ、本発明の目的とする快適な着用感と身体の動きに違和感なく追随するボディフィット性が得られない。因みに絹のヤング率は、６２ＣＮ／ｄｔｅｘであり、一般にレギュラー糸として市販されているポリエステルフィラメント糸のヤング率は１２４ＣＮ／ｄｔｅｘである。 In the present invention, the dye dyeable polyester filament yarn needs to have a Young's modulus of 85 CN / dtex or less, and preferably has a Young's modulus of 75 CN / dtex or less. If the Young's modulus exceeds 85 CN / dtex, the knitted fabric will be hard, and the comfortable fit and the body fit that follows the movement of the body, which is the object of the present invention, will not be obtained. Incidentally, the Young's modulus of silk is 62CN / dtex, and the Young's modulus of a polyester filament yarn generally marketed as a regular yarn is 124CN / dtex.
本発明におけるカチオン染料可染型ポリエステルフィラメント糸は、単糸（単繊維ともいわれる）繊度が１ｄｔｅｘ以下である必要がある。単糸繊度が１ｄｔｅｘを超えると、編地に硬さが感じられ、本発明の目的とする快適な着用感と身体の動きに違和感なく追随するボディフィット性が得られない。なお、絹の構成単糸繊度は、１．４〜３．１ｄｔｅｘ程度であり、細くて高級なものでも１ｄｔｅｘを超える。 The cationic dye dyeable polyester filament yarn in the present invention needs to have a single yarn (also referred to as single fiber) fineness of 1 dtex or less. When the single yarn fineness exceeds 1 dtex, the knitted fabric is felt to be hard, and the comfortable fit and the body fit that follows the movement of the body, which is the object of the present invention, cannot be obtained. In addition, the single yarn fineness of the silk is about 1.4 to 3.1 dtex, and even a thin and high-quality one exceeds 1 dtex.
本発明におけるカチオン染料可染型ポリエステルフィラメント糸は、カチオン染料により染色温度が１１０℃以下、好ましくは１０５℃以下で染色可能であることが必要である。染色温度が１１０℃を超えると、弾性糸の劣化が大きくなり、セット性も低下するため、使用可能な弾性糸が制約される。 Cationic dyeable polyester filament yarn of the present invention, dyeing temperature Ri by the cationic dye is 110 ° C. or less, preferably must be able stained with 105 ° C. or less. When the dyeing temperature exceeds 110 ° C., the elastic yarn is greatly deteriorated and the setability is also lowered, so that usable elastic yarn is restricted.
本発明における前記のヤング率、単糸繊度、染色性を有するカチオン染料可染型ポリエステルフィラメント糸としては、例えば、ポリエチレンテレフタレートに５−ナトリウムスルホイソフタル酸及びアジピン酸を共重合させたポリエステルポリマーを溶融紡糸することによって得られる。より具体的には、かかるポリエステルポリマーとして、ポリエチレンテレフタレートに５−ナトリウムスルホイソフタル酸０．５〜５．０モル％及びアジピン酸２．０〜１３．０モル％を共重合させたポリエステルポリマーが挙げられる。 Examples of the cationic dye dyeable polyester filament yarn having Young's modulus, single yarn fineness, and dyeability in the present invention include, for example, a polyester polymer obtained by copolymerizing polyethylene terephthalate with 5-sodium sulfoisophthalic acid and adipic acid. Obtained by spinning. More specifically, as such a polyester polymer, a polyester polymer obtained by copolymerizing polyethylene terephthalate with 0.5 to 5.0 mol% of 5-sodium sulfoisophthalic acid and 2.0 to 13.0 mol% of adipic acid is mentioned. It is done.
共重合させる５−ナトリウムスルホイソフタル酸が、０．５モル％未満では、カチオン染料可染性が不足するとともに、ヤング率が高くなり、糸のソフト感、やわらかさが不十分なものとなり、５．０モル％を超えると、フィラメント糸での繊維強度が低下する。またアジピン酸が２．０モル％未満では、染色温度を低くする効果が不十分であり、１３．０モル％を超えると、フィラメント糸としての繊維強度が低下する。 If the amount of 5-sodium sulfoisophthalic acid to be copolymerized is less than 0.5 mol%, the dyeability of the cationic dye is insufficient, the Young's modulus is increased, and the softness and softness of the yarn are insufficient. If it exceeds 0.0 mol%, the fiber strength of the filament yarn is lowered. Moreover, if adipic acid is less than 2.0 mol%, the effect which makes dyeing temperature low is inadequate, and if it exceeds 13.0 mol%, the fiber strength as a filament yarn will fall.
前記共重合ポリエステルポリマーは、溶融紡糸によって単糸繊度が１ｄｔｅｘ以下のフィラメント糸に製糸されるが、例えば、従来の紡糸方法の諸条件を、細繊度を得る条件にした紡糸方法、すなわち紡糸口金の孔径を小さくし、ポリマーの吐出量を小さくし、紡糸速度をひくくした条件で紡糸する方法で紡糸する等により、単糸繊度の細繊度化が行われ、製糸方法については特に限定するものではない。 The copolyester polymer is produced into a filament yarn having a single yarn fineness of 1 dtex or less by melt spinning. For example, a spinning method in which various conditions of a conventional spinning method are obtained to obtain a fineness, that is, a spinneret is used. The fineness of the single yarn is reduced by, for example, spinning by a method of spinning under the condition that the pore diameter is reduced, the discharge amount of the polymer is reduced, and the spinning speed is increased, and the spinning method is not particularly limited. .
本発明におけるカチオン染料可染型ポリエステルフィラメント糸は、前述の条件を満たしていれば、単糸の断面形状、表面形状、艶等を特に限定するものではないが、酸化チタン無添加のブライトの丸断面糸では、鮮明性や深色性に優れたものが得られ、酸化チタンを添加のフルダルとすることにより、紫外線カットの効果が得られる等、ポリエステルフィラメント糸の特長である機能性も十分に発揮することができる。また、カチオン染料可染型ポリエステルフィラメント糸の形態は、エア交絡のないものでもよいが、編成性向上のため、原糸製造段階でエア交絡処理され、エア交絡のあるものが好ましく用いられる。 The cationic dye-dyeable polyester filament yarn of the present invention is not particularly limited in terms of the cross-sectional shape, surface shape, gloss, etc. of the single yarn as long as the above-described conditions are satisfied. For cross-sectional yarns, those with excellent sharpness and deep color are obtained, and the functionality that is the feature of polyester filament yarn is sufficient, such as the effect of UV protection by obtaining titanium oxide-added full dull. It can be demonstrated. Further, the form of the cationic dyeable polyester filament yarn may be one without air entanglement, but in order to improve the knitting property, the one that is air entangled in the raw yarn manufacturing stage and has air entanglement is preferably used.
また、本発明において、弾性糸として、例えば、ポリエステル系ポリウレタン弾性糸、ポリエーテル系ポリウレタン弾性糸が挙げられ、その製法や種類を特に限定するものではない。これ等の弾性糸は、カチオン染料可染型ポリエステルフィラメント糸と共に用いられ、伸長性が極めて高く、小さな力で伸長するため、身体の動きに違和感なく追随するボディフィット性に優れたストレッチ編地を得る際に好適に用いられる。 In the present invention, examples of the elastic yarn include polyester-based polyurethane elastic yarn and polyether-based polyurethane elastic yarn, and the production method and type thereof are not particularly limited. These elastic yarns are used together with cationic dye dyeable polyester filament yarns, and have extremely high extensibility and stretch with a small force, so stretch knitted fabrics with excellent body fit that follows the movement of the body without a sense of incongruity. It is suitably used when obtaining.

(Comparative Example 1)
Cationic dye produced by melt spinning as in Example 2, except that the copolymerized polyethylene terephthalate polymer added with 1.5% by mass of titanium oxide as in Example 2 was used as the cationic dyeable polyester filament yarn. A dyeable polyester filament yarn fullal 56 dtex / 36f (single yarn round section, Young's modulus 70 CN / dtex, single yarn fineness 1.6 dtex) was used. This full dull filament yarn was twisted to 1000 T / m with S twist at a spindle rotation speed of 10000 rpm and a twist tension of 20 g by a double twister (manufactured by Murata Machinery Co., Ltd.), set at 80 ° C. for 40 minutes, and then placed on the front part to obtain 22 dtex. A polyether-based polyurethane elastic yarn (manufactured by Asahi Kasei Fibers Co., Ltd.) was placed in the back portion and knitted with a warp knitting machine (manufactured by KARL MAYER, gauge: 36G).
編立て組織は、フロント１−０／２−３、バック１−２／１−０のハーフ組織で、このときの編立密度機上コースは６０コース／吋で、前記ポリエステルフィラメント糸混率９０質量％、ポリウレタン弾性糸混率１０質量％であった。得られた生機を常法によりカチオン染料にて染色温度１０５℃で紺色に染色し、仕上げ巾１５０ｃｍ、ウエール７２／吋、コース１２４／吋、目付３１０ｇ／ｍ２に仕上げた。 得られた編地のストレッチ特性は、表１に示すとおりであり、得られた編地は、十分なストレッチ特性を有し、紫外線カット効果（紫外線遮蔽率９９％、ＵＰＦ値５０＋）も認められたが、編地の目付が大きいため、重量感、布厚感があり、身体の動きに追随するボディフィット性に違和感があった。また、得られた編地は、用いたカチオン染料可染型ポリエステルフィラメント糸の単糸繊度が太いことから、実施例１や実施例２での編地に比べて肌触りや編地のソフト感に劣るものであった。 The knitting structure is a half structure of a front 1-0 / 2-3 and a back 1-2 / 1-0, and the course on the knitting density machine is 60 courses / 吋, and the polyester filament yarn mixing ratio is 90 mass. %, And the polyurethane elastic yarn mixing ratio was 10% by mass. The obtained raw machine was dyed amber with a cationic dye at a dyeing temperature of 105 ° C. by a conventional method, and finished to a finishing width of 150 cm, a wale of 72 / 吋, a course of 124 / 吋, and a basis weight of 310 g / m 2 . The stretch characteristics of the obtained knitted fabric are as shown in Table 1. The obtained knitted fabric has sufficient stretch characteristics, and an ultraviolet cut effect (UV shielding rate 99%, UPF value 50+) is also recognized. However, since the basis weight of the knitted fabric was large, there was a sense of weight and fabric thickness, and there was a sense of incongruity in the body fit that followed the movement of the body. In addition, the obtained knitted fabric is thicker than the knitted fabric in Examples 1 and 2, because the single yarn fineness of the used cationic dyeable polyester filament yarn is thick. It was inferior.
