Abstract
Description
本発明は、優れた風合いを有し、寸法安定性に優れ、且つ軽量で嵩高であり、保温性に優れた編地に関する。 The present invention relates to a knitted fabric having excellent texture, excellent dimensional stability, lightweight and bulky, and excellent heat retention.
従来より、アクリル系繊維は他の汎用合成繊維であるポリアミド系繊維、ポリエステル繊維などと同様に、衣料用素材、インテリア用素材等の広範な分野に利用されているが、特にアクリル系繊維は比重が軽く、保温性に優れていることから、セーターや肌着用途などに多く利用されている。
保温性については熱の移動が大変重要であり、これまでにも保温性の向上について数多くの提案がなされている。例えば特許文献１では高収縮性アクリル系繊維を混紡することによって単繊維間の空隙を増し、これにより繊維内に空気を多く含み、空気の熱伝導率が低い特性を活かし、熱の伝導を防ぐことによって保温性を得ようとする提案がなされている。しかしながら、この提案では風合いと軽量感、保温性とを同時に満足することは困難であり、また十分な保温性を得ることが出来ない欠点を有している。
また特許文献２では、アクリル系繊維にセラミックを練り込み、遠赤外線を放射することにより、熱の輻射を利用し、保温性を得ようとする提案がされているが、セラミックを繊維に練り込んでいることにより、コストが高く、また風合いが悪くなる。
Conventionally, acrylic fibers have been used in a wide range of fields such as clothing materials and interior materials, as are other general-purpose synthetic fibers such as polyamide fibers and polyester fibers. In particular, acrylic fibers have a specific gravity. Because of its light weight and excellent heat retention, it is widely used for sweaters and underwear.
Regarding heat retention, heat transfer is very important, and many proposals for improving heat retention have been made so far. For example, in Patent Document 1, a high-shrinkage acrylic fiber is blended to increase the gaps between single fibers, thereby containing a large amount of air in the fiber and taking advantage of the low thermal conductivity of air to prevent heat conduction. Proposals have been made to obtain heat retaining properties. However, in this proposal, it is difficult to satisfy the texture, the lightness, and the heat retention at the same time, and there is a drawback that sufficient heat retention cannot be obtained.
Patent Document 2 proposes to obtain heat retention by kneading ceramic into acrylic fiber and radiating far infrared rays to obtain heat retention. However, ceramic is kneaded into fiber. The cost is high and the texture is poor.
本発明は、上記従来の欠点を解決せんとするものであって、優れた風合いを有し、表面タッチがソフトで、寸法安定性に優れ、且つ軽量で嵩高であり、保温性に優れた編地を提供することにある。 The present invention is to solve the above-mentioned conventional drawbacks, and has an excellent texture, soft surface touch, excellent dimensional stability, lightweight and bulky, and excellent heat retention. To provide the ground.
上記目的を達成するため、本発明は次の構成からなる。
すなわち、沸水収縮率が１５％以上で、単繊維繊度が０．７〜２．２ｄｔｅｘの高収縮性アクリル繊維と、沸水収縮率１０％以下の低収縮性繊維からなる編地であり、比容積が６〜１２ｃｍ３／ｇ、保温率が２８〜６０％の編地である。
また、本発明の編地は高収縮性アクリル繊維が３０〜５０重量％と、低収縮性繊維が５０〜７０重量％からなる紡績糸を用いてなる編地であり、前記紡績糸が単独で用いられていても、他の糸条と交編されていても良い。
In order to achieve the above object, the present invention comprises the following arrangement.
That is, a knitted fabric comprising a highly shrinkable acrylic fiber having a boiling water shrinkage of 15% or more and a single fiber fineness of 0.7 to 2.2 dtex and a low shrinkage fiber having a boiling water shrinkage of 10% or less, and a specific volume. Is a knitted fabric having 6 to 12 cm 3 / g and a heat retention of 28 to 60%.
The knitted fabric of the present invention is a knitted fabric using a spun yarn comprising 30 to 50% by weight of high-shrinkage acrylic fibers and 50 to 70% by weight of low-shrinkage fibers, and the spun yarn is used alone. It may be used or knitted with other yarns.
以下に本発明を詳細に説明する。 The present invention is described in detail below.
本発明の高収縮性アクリル繊維はアクリロニトリルと、アクリロニトリルと共重合可能な不飽和単量体とを共重合してなるアクリル系ポリマーを紡糸して得られる。アクリロニトリル単位の含有量は、アクリル系ポリマー中、９０質量％以上、９５質量％以下であることが好ましい。アクリロニトリル単位の含有量が９０質量％未満の場合は、繊維とした場合の物性が劣る傾向にあり、９５質量％を超える場合は、高収縮性アクリル繊維を得ることが難しい。 The highly shrinkable acrylic fiber of the present invention can be obtained by spinning an acrylic polymer obtained by copolymerizing acrylonitrile and an unsaturated monomer copolymerizable with acrylonitrile. The content of acrylonitrile units is preferably 90% by mass or more and 95% by mass or less in the acrylic polymer. When the content of the acrylonitrile unit is less than 90% by mass, the physical properties of the fiber tend to be inferior, and when it exceeds 95% by mass, it is difficult to obtain a highly shrinkable acrylic fiber.
アクリロニトリルと共重合可能な不飽和単量体としては特に限定されないが、例えばアクリル酸、アクリル酸メチル、アクリルアミド、塩化ビニル、塩化ビニリデン、ビニルベンゼンスルホン酸ナトリウム、メタリルスルホン酸ナトリウム、アクリルアミドメチルスルホン酸ナトリウム等があげられる。 The unsaturated monomer copolymerizable with acrylonitrile is not particularly limited. For example, acrylic acid, methyl acrylate, acrylamide, vinyl chloride, vinylidene chloride, sodium vinylbenzenesulfonate, sodium methallylsulfonate, and acrylamidomethylsulfonic acid. Examples include sodium.
本発明の高収縮性アクリル繊維は沸水収縮率が１５％以上であり、単繊維繊度が０．７〜２．２ｄｔｅｘであることが重要である。沸水収縮率が１５％未満の場合は十分なバルキー性を付与することが出来ないため、軽量感、嵩高感、保温性に劣るものとなる。軽量で嵩高であり、保温性に優れた編地を得るためには、沸水収縮率３０％以上の高収縮性アクリル繊維を用いることが好ましい。また、単繊維繊度が０．７ｄｔｅｘ未満の場合は、紡績工程通過性が悪く、工業生産上好ましくない。逆に単繊維繊度が２．２ｄｔｅｘを超える場合は、編地風合いを損ねるため好ましくない。 It is important that the highly shrinkable acrylic fiber of the present invention has a boiling water shrinkage of 15% or more and a single fiber fineness of 0.7 to 2.2 dtex. When the boiling water shrinkage is less than 15%, sufficient bulkiness cannot be imparted, resulting in poor lightness, bulkiness and heat retention. In order to obtain a knitted fabric that is light and bulky and excellent in heat retention, it is preferable to use a highly shrinkable acrylic fiber having a boiling water shrinkage of 30% or more. Moreover, when the single fiber fineness is less than 0.7 dtex, the spinning process passability is poor, which is not preferable for industrial production. Conversely, when the single fiber fineness exceeds 2.2 dtex, the knitted fabric texture is impaired, which is not preferable.
沸水収縮率が１５％以上の高収縮性アクリル繊維は、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。高収縮性アクリル繊維と低収縮性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物が得られる。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。 Highly shrinkable acrylic fibers having a boiling water shrinkage of 15% or more can be produced by appropriately combining known techniques such as high shrinkage raw cotton and a check sliver in tow spinning. A knitted fabric having excellent swelling and lightness can be obtained by combining a high shrinkage acrylic fiber and a low shrinkage fiber to obtain a blended yarn and then giving a bulky property by heat treatment in a dyeing process. 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.
本発明の編地は比容積が６〜１２ｃｍ３／ｇである。比容積が６ｃｍ３／ｇ以上であることにより、本発明の目的である軽量感と嵩高感に優れ、且つ保温性の高い編地となる。また、比容積が１２ｃｍ３／ｇ以下であれば、編地として実用上の問題発生が少ない。 The knitted fabric of the present invention has a specific volume of 6 to 12 cm 3 / g. When the specific volume is 6 cm <3> / g or more, the knitted fabric is excellent in lightness and bulkiness, which is the object of the present invention, and has high heat retention. In addition, when the specific volume is 12 cm 3 / g or less, there are few problems in practical use as a knitted fabric.
本発明の編地は保温率が２８〜６０％であることが重要である。保温率が２８％以上であることで優れた保温性を得ることが出来る。本発明の編地において、保温率の上限は６０％である。 It is important that the knitted fabric of the present invention has a heat retention rate of 28 to 60%. When the heat retention rate is 28% or more, excellent heat retention can be obtained. In the knitted fabric of the present invention, the upper limit of the heat retention rate is 60%.
本発明の編地においては、保温率と比容積の両方を満足することが重要である。保温率が２８％以上であっても、比容積が６ｃｍ３／ｇ未満の場合は、本発明の目的である、軽量感と嵩高感に優れ、且つ保温性の高い編地とはならない。すなわち、この両方の数値を満たすことにより、軽量感と嵩高感に優れ、且つ保温性の高い編地となる。 In the knitted fabric of the present invention, it is important to satisfy both the heat retention rate and the specific volume. Even if the heat retention rate is 28% or more, when the specific volume is less than 6 cm 3 / g, the knitted fabric which is the object of the present invention is excellent in lightness and bulkiness and has high heat retention. That is, by satisfying both of these numerical values, the knitted fabric is excellent in lightness and bulkiness and has high heat retention.
本発明の低収縮性繊維は、沸水収縮率が１０％以下の繊維であれば特に限定するものではなく、アクリル短繊維、ポリエステル短繊維、レーヨンスフ、綿、羊毛等を用いることが出来る。例えば、編地に抗ピル性を付与するために、低収縮繊維として抗ピルアクリル繊維を使用しても良い。また、低収縮繊維の単繊維繊度についても特に限定することはなく、製品用途によって最適な組み合わせを選定すれば良い。前記高収縮性アクリル繊維と低収縮繊維を混紡糸として用いる場合は、高収縮性アクリル繊維を３０〜５０重量％、低収縮繊維を５０〜７０重量％の割合で混紡すればよい。低収縮繊維としては、例えば抗ピル性アクリル短繊維を単独で用いても良く、アクリル繊維とレーヨンスフを任意の割合で併用するなど、製品用途や目的とする風合いを得るために適宜選定すれば良い。 The low shrinkable fiber of the present invention is not particularly limited as long as it has a boiling water shrinkage of 10% or less, and acrylic short fiber, polyester short fiber, rayon suf, cotton, wool and the like can be used. For example, an anti-pill acrylic fiber may be used as the low shrinkage fiber in order to impart anti-pill property to the knitted fabric. Moreover, the single fiber fineness of the low shrinkage fiber is not particularly limited, and an optimal combination may be selected depending on the product application. When the high-shrinkage acrylic fiber and the low-shrinkage fiber are used as a blended yarn, the high-shrinkage acrylic fiber may be blended at a ratio of 30 to 50% by weight and the low-shrinkage fiber at a ratio of 50 to 70% by weight. As the low shrinkage fiber, for example, an anti-pill-resistant acrylic short fiber may be used alone, or may be appropriately selected in order to obtain a product texture and a desired texture, such as using acrylic fiber and rayon suf in combination at an arbitrary ratio. .
