Description
本発明は、目付が小さく軽量でありながら、保温性に優れた編地とその製造方法に関する。
The present invention relates to a knitted fabric having a small basis weight and light weight and excellent in heat retention and a method for producing the same.
近年の保温肌着用の編地開発においては、吸湿発熱性能等の機能性付与が中心となっているが、単純に機能性繊維を組み合わせるだけでは、編地の風合いが損なわれかねない。また保温性を良くするには編地を厚くするのが効果的であるが、厚手の肌着は着膨れすることにより動作に支障をきたし、作業性を損なう可能性があることから、軽量でかつ風合いが良く温かな肌着用の編地開発が求められている。
In recent years, the development of knitted fabrics for wearing warm skin has been focused on providing functionality such as hygroscopic heat generation performance, but simply combining functional fibers can damage the texture of the knitted fabric. In order to improve heat retention, it is effective to make the knitted fabric thicker, but thick undergarments are difficult to operate due to swelling and may reduce workability. The development of knitted fabrics that wear well and warm skin is required.
特許文献1には、紡績糸とフィラメント糸の交編による編地の作成方法が提案されているが、用いられる紡績糸には収縮性繊維が含まれておらず、非収縮繊維の紡績糸とフィラメント糸との交編編地であり、軽量感はあるものの、保温性は十分でなかった。
Patent Document 1 proposes a method of creating a knitted fabric by knitting a spun yarn and a filament yarn, but the spun yarn used does not contain shrinkable fibers, and a spun yarn of non-shrinkable fibers and This is a knitted knitted fabric with filament yarn, and although there is a feeling of lightness, the heat retaining property was not sufficient.
特許文献2には、高収縮繊維を用いる紡績糸の製造方法が記載されているが、この方法は精紡工程にて高収縮繊維を混ぜ合わせる加工方法であり、紡績糸は綛工程で湿熱加工することで糸に収縮を発現させたのちに、横編み工程で編地作成に適用されるに好適な軽量紡績糸を作成する方法であることから、編地としては良好な保温性が得られるものの、その保温性を確保しようとすると編地の目付や布厚を大きくせざるを得なくなり、編地を軽量にすることができなかった。
Patent Document 2 describes a method for producing a spun yarn using high-shrinkage fibers. This method is a processing method for mixing high-shrinkage fibers in a spinning process, and the spun yarn is processed by wet heat in a wrinkle process. This is a method of creating a lightweight spun yarn suitable for being applied to knitted fabric production in the flat knitting process after causing the yarn to shrink, so that good heat retention can be obtained as a knitted fabric. However, in order to ensure the heat retention, the fabric weight and fabric thickness of the knitted fabric had to be increased, and the knitted fabric could not be reduced in weight.
本発明の目的は、目付が小さく軽量でありながら、保温性に優れた編地を提供することにあり、またこうした軽量で保温性に優れた編地を商業的に得ることにある。

紡績糸Aと糸Bとの交編率が2:1~1:3であることで、紡績糸Aは収縮して糸自体が膨らみを持ち、紡績糸Aの収縮に伴い糸Bが弛むことで編地に膨らみが出る。
紡績糸Aと糸Bの交編が、2:1であれば、紡績糸Aの比率が多くなり過ぎないため、糸Bによる編地の膨らみ感が得られ、1:3であれば、紡績糸Aの収縮が十分起こり、紡績糸A自体の膨らみと、糸Bの弛みによる編地の膨らみ感が得られる。
これらの観点から、紡績糸Aと糸Bとの交編率は1:1~1:2がより好ましく、1:1がさらに好ましい。

When the knitting ratio between the spun yarn A and the yarn B is 2: 1 to 1: 3, the spun yarn A contracts and the yarn itself swells, and the spun yarn A loosens as the spun yarn A contracts. Then the knitted fabric swells.
If the knitting of the spun yarn A and the yarn B is 2: 1, the ratio of the spun yarn A does not increase so much that a feeling of swelling of the knitted fabric by the yarn B can be obtained. The contraction of the yarn A occurs sufficiently, and the swell of the spun yarn A itself and the feeling of the knitted fabric due to the slack of the yarn B can be obtained.
From these viewpoints, the knitting ratio of the spun yarn A and the yarn B is more preferably 1: 1 to 1: 2, and more preferably 1: 1.
The knitting rate is the ratio of the number of the spun yarn A and the yarn B arranged. For example, when the knitting rate of the spun yarn A and the yarn B is 1: 2, one spun yarn A is arranged. On the other hand, two yarns B are arranged.
本発明の編地は、アクリル繊維を含有し、伸度が15%~30%の糸である紡績糸Aと、メートル番手で40番手~350番手である糸Bとの交編率が2:1~1:3である。

The knitted fabric of the present invention has an knitting ratio of 2: spun yarn A, which contains acrylic fibers and has an elongation of 15% to 30%, and yarn B, which is 40 to 350 in metric count, and 2: 1 to 1: 3.
When the knitting ratio between the spun yarn A and the yarn B is 2: 1 to 1: 3, the spun yarn A contracts and the yarn itself swells, and the spun yarn A loosens as the spun yarn A contracts. Then the knitted fabric swells.
If the knitting of the spun yarn A and the yarn B is 2: 1, the ratio of the spun yarn A does not increase so much that a feeling of swelling of the knitted fabric by the yarn B can be obtained.

これらの観点から、前記伸度は20%~29%がより好ましく、23%~28%がさらに好ましい。 In the knitted fabric of the present invention, the spun yarn A is a yarn containing acrylic fibers and having an elongation of 15% to 30%.
When the spun yarn A contains acrylic fibers, a spun yarn having a high shrinkage can be obtained. As a result of the spun yarn being shrunk, the elongation can be 15% to 30%. If the elongation is 15% or more, the spun yarn can be shrunk until it swells, and if the elongation is 30% or less, the dimensional stability of the knitted fabric becomes good.

本発明の編地の製造方法において、用いる紡績糸aは、一般的な綿紡績の手法によって得ることができる。
紡績糸aを構成する繊維は、高収縮性繊維、好ましくは高収縮性アクリル繊維が紡績糸に対して30質量%~45質量%含まれ、さらに他の繊維が混紡されて含む。この際、高収縮性繊維の混率が30質量%未満であると紡績糸に湿熱を加えたときの収縮力が弱く、目的とする紡績糸が収縮して太くなるという糸の構造変化が起きないため、編地となった際に十分な保温性を得ることができない。また高収縮性繊維の混率が45質量%を超えると湿熱を加えた際の収縮力は十分であるが、編地表面に現れる他の繊維が少なくなることで風合いが損なわれる。 (Spun yarn used for knitted fabric production)
In the method for producing a knitted fabric of the present invention, the spun yarn a used can be obtained by a general cotton spinning technique.
The fiber constituting the spun yarn a contains a high-shrinkage fiber, preferably a high-shrinkage acrylic fiber in an amount of 30% to 45% by weight with respect to the spun yarn, and further contains other fibers blended. At this time, if the mixing ratio of the highly shrinkable fiber is less than 30% by mass, the shrinkage force when wet heat is applied to the spun yarn is weak, and the structural change of the yarn that the target spun yarn shrinks and thickens does not occur. Therefore, sufficient heat retention cannot be obtained when it becomes a knitted fabric. On the other hand, when the mixing ratio of the highly shrinkable fibers exceeds 45% by mass, the shrinkage force when wet heat is applied is sufficient, but the texture is impaired by the reduction of other fibers appearing on the surface of the knitted fabric.

To knit the spun yarn a and the other yarn B at a ratio of 2: 1 means that two courses are knitted with the spun yarn a and then one course is knitted with the yarn B. In the case of circular knitting, knitting can be performed by standing two spun yarns a and one yarn B at the yarn feeder and repeating them. In the case of weft knitting, the spun yarn a is knitted for two courses, then the yarn is switched from the spun yarn a to the yarn B, and knitted for one course, and this is repeated.
