Description

本発明は、単繊維繊度が0.8〜3.3dtexの範囲にある合成繊維と天然繊維とからなる混紡糸、さらに機能性を付与した前記混紡糸およびそれらの混紡糸を含む編物に関する。   The present invention relates to a blended yarn comprising a synthetic fiber and a natural fiber having a single fiber fineness in a range of 0.8 to 3.3 dtex, a blended yarn imparted with functionality, and a knitted fabric including the blended yarn.

従来から肌着用素材として、綿繊維のみを使用した紡績糸、アクリル繊維等の合成繊維と綿繊維を混紡した紡績糸、再生セルロース繊維とアクリル繊維等の合成繊維を混紡した紡績糸などがある。合成繊維と綿繊維との混紡品は綿繊維の比率が高くなると、編地を握ったときの感触が硬くなり易く、洗濯後の編地は、より感触も硬くなり、また形態が崩れやすい傾向がある。主な用途としては紳士用肌着が中心である。再生セルロース繊維と合成繊維の混紡品は洗濯後の形態安定性に欠けるが、吸湿発熱性に優れ、光沢があり、編地を握ったときの感触が柔らかい事から、婦人用肌着に好んで使用される傾向にある。   Conventionally, as skin-wearing materials, there are spun yarn using only cotton fibers, spun yarn obtained by blending synthetic fibers such as acrylic fibers and cotton fibers, and spun yarn obtained by blending synthetic fibers such as regenerated cellulose fibers and acrylic fibers. When the ratio of cotton fibers to synthetic fiber and cotton fiber blends increases, the feel when gripping the knitted fabric tends to become harder, and the knitted fabric after washing tends to become harder and more fragile. There is. The main use is mainly underwear for men. A blend of regenerated cellulose fiber and synthetic fiber lacks form stability after washing, but is superior in hygroscopic heat generation, glossy, and soft to the touch when grasping a knitted fabric. Tend to be.

その中で機能面から再生セルロース繊維の吸湿発熱性に着目することで、合成繊維と吸湿発熱性繊維を混紡した吸湿発熱性および保温効果の高い布帛が開示されている(特許文献1)。   Among them, by paying attention to the hygroscopic exothermic property of the regenerated cellulose fiber from the functional aspect, a fabric having a high hygroscopic exothermic property and a heat retaining effect obtained by blending synthetic fiber and hygroscopic exothermic fiber has been disclosed (Patent Document 1).

また架橋アクリル系繊維を含む紡績糸と弾性糸とを組み合わせることで、吸湿発熱性および保温効果が高く、着用時の身体へのフィット性の向上を特徴とする提案が開示されている(特許文献2)。   In addition, a proposal has been disclosed that combines a spun yarn containing a cross-linked acrylic fiber and an elastic yarn with high heat absorption and heat retention effect and improved fit to the body when worn (patent document) 2).

(アクリロニトリル重合体)
本発明の紡績糸に用いるアクリル繊維の原料としては、通常のアクリル繊維の製造に用いるアクリロニトリル重合体であればよく、特に限定しない。前記重合体の構成は、50質量%以上のアクリロニトリル単位を含有していることが必要である。これによりアクリル繊維本来の特性を発現することができる。
Details of the present invention will be described below.
(Acrylonitrile polymer)
The raw material of the acrylic fiber used for the spun yarn of the present invention is not particularly limited as long as it is an acrylonitrile polymer used for production of a normal acrylic fiber. The composition of the polymer needs to contain 50% by mass or more of acrylonitrile units. Thereby, the original characteristic of acrylic fiber can be expressed.

アクリロニトリルと共重合する単量体は、共重合可能であれば特に限定されないが、例えばアクリル酸メチル、アクリル酸エチル、アクリル酸イソプロピル、アクリル酸n−ブチル、アクリル酸2−エチルヘキシル、アクリル酸2−ヒドロキシエチルなどに代表されるアクリル酸エステル類、メタクリル酸メチル、メタクリル酸エチル、メタクリル酸イソプロピルなどに代表されるメタクリル酸エステル類、さらにアクリル酸、メタクリル酸、マレイン酸、イタコン酸、アクリルアミド、スチレン、ビニルトルエン、酢酸ビニル、塩化ビニル、塩化ビニリデン、臭化ビニル、臭化ビニリデン、フッ化ビニル、フッ化ビニリデンなどが挙げられる。

(アクリル繊維)
本発明の紡績糸に好適なアクリル繊維は、例えば次のようにして得ることができる。水系懸濁重合法によりアクリロニトリル93質量%、酢酸ビニル7質量%からなる共重合体を得る。続いて前記共重合体をジメチルアセトアミドに溶解し、重合体濃度20質量%の紡糸原液を得る。前記紡糸原液を丸型形状の吐出孔を具備したノズル口金を用い、溶剤30〜60質量%、水が70〜40質量%、温度30〜50℃の凝固浴中で湿式紡糸する。吐出孔数は特に規定しない。紡糸後に湿熱で延伸倍率3〜5倍の延伸処理を施し、続いて油剤を付着させ150℃の熱ローラーで乾燥緻密化後、更に乾熱で延伸倍率1.1〜2倍の延伸処理を施した後、必要に応じて加圧水蒸気下で熱収縮処理を行う。このようにして得られたアクリル繊維は、単繊維繊度が0.8〜1.3dtexの範囲にあるアクリル繊維が好ましい。単繊維繊度が0.8dtex以上であれば紡績工程でのトラブルが発生しにくくまた、単繊維繊度が1.3dtex以下であればことなく、編地を握ったときの感触が柔らかいものとなる前記観点から、単繊維繊度は、0.9〜1.2dtexの範囲にあることがより好ましい。
(Acrylic fiber)
An acrylic fiber suitable for the spun yarn of the present invention can be obtained, for example, as follows. A copolymer comprising 93% by mass of acrylonitrile and 7% by mass of vinyl acetate is obtained by an aqueous suspension polymerization method. Subsequently, the copolymer is dissolved in dimethylacetamide to obtain a spinning dope having a polymer concentration of 20% by mass. The spinning dope is wet-spun in a coagulation bath of 30-60 mass% solvent, 70-40 mass% water, and 30-50 ° C. temperature using a nozzle die having a round discharge hole. The number of discharge holes is not specified. After spinning, the film is stretched at a stretch ratio of 3 to 5 times with wet heat, and then an oil agent is attached, dried and densified with a heat roller at 150 ° C., and further stretched at a stretch ratio of 1.1 to 2 with dry heat. Then, if necessary, heat shrink treatment is performed under pressurized steam. The acrylic fiber thus obtained is preferably an acrylic fiber having a single fiber fineness in the range of 0.8 to 1.3 dtex. If the single fiber fineness is 0.8 dtex or more, troubles in the spinning process are unlikely to occur, and the single fiber fineness is 1.3 dtex or less, and the feel when grasping the knitted fabric is soft From the viewpoint, the single fiber fineness is more preferably in the range of 0.9 to 1.2 dtex.

(高収縮アクリル繊維)
本発明の紡績糸に使用する高収縮アクリル繊維は沸水収縮率が15%〜45%であり、単繊維繊度が0.8〜1.3dtexの範囲にあるアクリル繊維が好ましい。沸水収縮率が15%以上であれば編地に優れたまた、沸水収縮率が45%以下であれば、収縮後の編地風合いが硬くなりすぎず、編地を握ったときの感触が柔らかいものとなる。前記観点から沸水収縮率は18%〜40%の範囲にあることがより好ましい。
(High shrinkage acrylic fiber)
The highly shrinkable acrylic fiber used in the spun yarn of the present invention is preferably an acrylic fiber having a boiling water shrinkage of 15% to 45% and a single fiber fineness in the range of 0.8 to 1.3 dtex. If the boiling water shrinkage is 15% or more, the knitted fabric is excellent. If the boiling water shrinkage is 45% or less, the texture of the knitted fabric after shrinkage does not become too hard and the feel when gripping the knitted fabric is soft. It will be a thing. From the above viewpoint, the boiling water shrinkage is more preferably in the range of 18% to 40%.

また、単繊維繊度は0.8dtex以上であれば紡績工程でのトラブルが発生しにくくまた、単繊維繊度が1.3dtex以下であれば収縮後のことなく、編地を握ったときの感触が柔らかいものとなる前記観点から、単繊維繊度は、0.9〜1.2dtexの範囲にあることがより好ましい。   In addition, if the single fiber fineness is 0.8 dtex or more, troubles in the spinning process are unlikely to occur, and if the single fiber fineness is 1.3 dtex or less, the feeling when gripping the knitted fabric is obtained without shrinking. From the viewpoint of being soft, the single fiber fineness is more preferably in the range of 0.9 to 1.2 dtex.

沸水収縮率が15%〜45%である高収縮アクリル繊維は、高収縮原綿、トウ紡績での牽切スライバーなど、公知の技術を適宜組み合わせて製造することが出来る。高収縮アクリル繊維と低収縮繊維とを組み合わせて、混紡糸とした後、染色工程での熱処理によりバルキー性を与えることで、膨らみのある軽量感に優れた編地が得られる。更には紡績糸を構成する繊維間の空隙を増大させるとともに、空気層による熱遮断性を高めることによる、保温性向上効果も得られる。   High shrinkage acrylic fibers having a boiling water shrinkage of 15% to 45% can be produced by appropriately combining known techniques such as high shrinkage raw cotton and a check sliver in tow spinning. By combining high-shrinkage acrylic fibers and low-shrinkage fibers into a blended yarn and then giving a bulky property by heat treatment in the dyeing process, a knitted fabric excellent in lightness with swelling can be obtained. Furthermore, while increasing the space | gap between the fibers which comprise a spun yarn, the heat insulation improvement effect by improving the heat-shielding property by an air layer is also acquired.

高収縮アクリル繊維の紡績糸における混率は、25〜50質量%が好ましい。高収縮アクリル繊維の紡績糸における混率が25質量%以上であれば、熱処理時における収縮斑が発生しにくいため、編地の品位を損なうことがない。また、高収縮アクリル繊維の紡績糸における混率が50質量%以下であれば、収縮後のことなく、編地を握ったときの感触が柔らかいものとなる。前記観点から、高収縮アクリル繊維の紡績糸における混率は、30〜40質量%の範囲にあることがより好ましい。   The mixing ratio in the spun yarn of the highly shrinkable acrylic fiber is preferably 25 to 50% by mass. If the mixing ratio in the spun yarn of the high shrinkage acrylic fiber is 25% by mass or more, shrinkage spots are hardly generated during the heat treatment, and the quality of the knitted fabric is not impaired. Moreover, if the mixture ratio in the spun yarn of highly shrinkable acrylic fibers is 50% by mass or less, the feel when grasping the knitted fabric is soft without being shrunk. From the above viewpoint, the mixing ratio in the spun yarn of the highly shrinkable acrylic fiber is more preferably in the range of 30 to 40% by mass.

(導電性アクリル繊維)
アクリル繊維として、導電性アクリル繊維を含むと紡績糸に制電性能を付与できる。導電性アクリル繊維は、アクリル繊維に導電性物質を混合することにより得られる。アクリル繊維に混合する導電性物質としては特に限定するものではないが、Fe、Cu、Al、Pb、Sn、Au、Ag、Ni等に代表される金属類およびそれらの酸化物、硫化物、カルボニル塩、またはITO(インジウム・スズ酸化物)、ATO(アンチモン・スズ酸化物)、酸化亜鉛等の導電性金属酸化物およびこれらの硫酸バリウム、酸化チタン、チタン酸カリウム、アルミニウムの担体微粒子にコーティングした非金属系導電材、ファーネス、チャンネル、サーマル、アセチレンブラックに代表されるカーボンブラック系導電材、およびポリアセチレン、ポリピロール、ポリアニリン等に代表される導電性高分子化合物、テトラシアノパラキノジメタン(TCNQ)、テトラチアフルバレン(TTF)との錯体に代表される有機導電性化合物等が挙げられる。
(Conductive acrylic fiber)
When conductive acrylic fiber is included as the acrylic fiber, antistatic performance can be imparted to the spun yarn. The conductive acrylic fiber can be obtained by mixing a conductive substance with the acrylic fiber. The conductive material mixed with the acrylic fiber is not particularly limited, but metals represented by Fe, Cu, Al, Pb, Sn, Au, Ag, Ni, etc., and oxides, sulfides, and carbonyls thereof. It was coated on carrier fine particles of salt or conductive metal oxides such as ITO (indium tin oxide), ATO (antimony tin oxide), zinc oxide, and barium sulfate, titanium oxide, potassium titanate, and aluminum. Non-metallic conductive material, furnace, channel, thermal, carbon black conductive material typified by acetylene black, and conductive polymer compound typified by polyacetylene, polypyrrole, polyaniline, tetracyanoparaquinodimethane (TCNQ) , Organic conductors represented by complexes with tetrathiafulvalene (TTF) Sexual compounds.

これら導電性物質の混合手段としては、アクリル繊維製造時の紡糸原液に導電性物質を均一分散混合した練り込み繊維としても良いが、紡糸安定性、耐久性、導電性能を考慮すると、芯部に導電性物質を練りこんだ芯鞘型複合紡糸による方法が好ましい。   As a means for mixing these conductive substances, a kneaded fiber in which a conductive substance is uniformly dispersed and mixed in a spinning stock solution at the time of acrylic fiber production may be used, but considering the spinning stability, durability, and conductive performance, A method by core-sheath type composite spinning in which a conductive substance is kneaded is preferable.

また、導電性アクリル繊維の別の機能として、光エネルギーを熱エネルギーに変換する(光吸収発熱性)機能を有する導電性アクリル繊維を使用すると、紡績糸に制電性能のみならず、発熱機能も付与することが可能であり、より好ましい。   As another function of the conductive acrylic fiber, if conductive acrylic fiber having a function of converting light energy into heat energy (light absorption heat generation) is used, not only the antistatic performance but also the heat generation function of the spun yarn It is possible to give, and it is more preferable.

Moreover, if the mixing rate in the spun yarn of the conductive acrylic fiber is 10% by mass or less, it is possible to prevent deterioration in knitted fabric quality and dyeability due to coloring derived from the conductive acrylic fiber. In addition, when using the conductive acrylic fiber which has light absorption exothermic property, it is preferable that the mixture rate in a spun yarn shall be 5-10 mass%.

消臭性アクリル繊維の紡績糸における混率は、20〜40質量%が好ましい。消臭性アクリル繊維の紡績糸における混率が20質量%以上であれば、編地に消臭性能を付与することが出来る。また、消臭性アクリル繊維の紡績糸における混率が40質量%以下であれば、消臭性アクリル繊維に由来する染色性の低下、糸強力の低下を防ぐことが出来る。前記観点から、消臭性アクリル繊維の紡績糸における混率は、25〜35質量%の範囲にあることがより好ましい。   The mixing ratio in the spun yarn of the deodorant acrylic fiber is preferably 20 to 40% by mass. If the mixing ratio in the spun yarn of the deodorant acrylic fiber is 20% by mass or more, deodorant performance can be imparted to the knitted fabric. Moreover, if the mixing rate in the spun yarn of a deodorant acrylic fiber is 40 mass% or less, the fall of the dyeability derived from a deodorant acrylic fiber and the fall of yarn strength can be prevented. From the said viewpoint, it is more preferable that the mixing rate in the spun yarn of deodorant acrylic fiber exists in the range of 25-35 mass%.

(紡績糸の製造方法)
本発明の紡績糸の製造には綿紡績で使用される設備を用いる。紡績糸の原材料比率になるように、各繊維を計量したのち、開綿機に投入し混ぜ合わせる。混合された原材料を打綿機に投入した後、ラップを形成する。次にラップをフラットカードに投入し、スライバーを作成する。この場合、使用するフラットカードのトップ数は70本以上、出来れば100本以上ある機台が望ましい。また、品位向上の為には固定フラットを装備した機台を使用することが望ましい。スライバー作成後、錬条工程を2回以上通したのち、粗紡工程を経て、粗糸を作成する。この場合の粗糸撚り数の設定は20回/インチとなるようにする。粗糸の撚り数が高すぎると、精紡での異常ドラフトの原因となり、紡績糸の斑が増加し品位の低下に繋がる。得られた粗糸をリング精紡機で紡績糸を作成する。紡績糸のメートル番手は64〜90の範囲内であることが好ましいワインダー工程において紡績糸中の欠点除去を行った後、コーンに巻き取る。
(Method for producing spun yarn)
The production of the spun yarn of the present invention uses equipment used for cotton spinning. Each fiber is weighed so that it becomes the raw material ratio of the spun yarn, and then put into a cotton spreader and mixed. After the mixed raw materials are put into a cotton blower, a wrap is formed. Next, put the lap into the flat card and create a sliver. In this case, it is desirable that the number of flat cards used is 70 or more, preferably 100 or more. In order to improve the quality, it is desirable to use a machine base equipped with a fixed flat. After the sliver is created, the roving process is performed twice or more, and then the roving process is performed to create the roving yarn. In this case, the setting of the number of twists of the roving is 20 times / inch. If the number of twists of the roving yarn is too high, it will cause an abnormal draft in fine spinning, resulting in an increase in spatter yarn spots and a reduction in quality. A spun yarn is produced from the obtained roving yarn with a ring spinning machine. In the winder process, the spun yarn preferably has a metric count of 64 to 90. After removing defects in the spun yarn, it is wound around a cone.

(紡績工程の撚り数設定方法)
編物用途に用いる紡績糸は、編地を握ったときの感触を柔らかくすること、および、毛羽を減らすために撚り数が重要であり、撚り係数(α)が105〜110の間で設定することが好ましい。撚り数は下記式により決定される。
撚り数(回/m)=撚り係数(α)×√紡績糸番手(メートル番手)
(Method of setting the number of twists in the spinning process)
For spun yarn used for knitting, the number of twists is important to soften the feel when grasping the knitted fabric and to reduce fluff, and the twist coefficient (α) should be set between 105 and 110 Is preferred. The number of twists is determined by the following formula.
Number of twists (times / m) = twisting coefficient (α) × √spun yarn count (metric count)

撚り係数が105以上であれば、編地を編み立てる際に必要な糸強度を保つことが出来る。また、撚り係数が110以下であれば、編地を握ったときの風合いが硬くなりすぎるのを防止できる。
また、紡績糸は、撚りトルクの発現を抑える為に、例えば温度60℃、時間15分又は、温度80℃、時間7分間のスチームセットが施される。
If the twist coefficient is 105 or more, the yarn strength necessary for knitting the knitted fabric can be maintained. Moreover, if a twist coefficient is 110 or less, it can prevent that the texture when grasping a knitted fabric becomes too hard.
The spun yarn is subjected to steam setting at a temperature of 60 ° C. for 15 minutes or a temperature of 80 ° C. for 7 minutes in order to suppress the expression of twisting torque.

(編地作成方法)
編み立て工程は、公知の丸編機を用いて編み立てを実施する。編機の種類は特に限定せず、シングル編機、ダブル編機、パイル編機など、目的とする編地組織を得るために適宜選定すれば良い。編み立ての際、糸の走行テンションを10〜25gの範囲とする。この範囲を超えると紡績糸と編機の糸ガイドとの接触によるフライ発生量が増大し、糸切れ発生の増大及び風綿の飛び込みにより、穴開き等による編地品位の低下の要因となる。
(Knitting fabric creation method)
In the knitting process, knitting is performed using a known circular knitting machine. The type of the knitting machine is not particularly limited, and may be appropriately selected to obtain a desired knitted fabric structure such as a single knitting machine, a double knitting machine, or a pile knitting machine. At the time of knitting, the running tension of the yarn is in the range of 10 to 25 g. If this range is exceeded, the amount of fly generated due to the contact between the spun yarn and the yarn guide of the knitting machine increases, which causes a decrease in knitted fabric quality due to perforations and the like due to increased yarn breakage and jumping of fluff.

(染色方法)
編地の染色には、液流染色機を用いるとよい。染色工程は、例えば、45℃の染色液を1℃/2分の温度上昇条件で液温を100℃とした後、その状態を20分間保持する工程とする。この時は液流がダウンブローとなるタイプを用いる事が品位向上に適している。液流がダウンブローとなる事で、編地に余分な張力が掛かる事がなく、編地を握ったときの感触を柔らかく仕上げることが出来る。
