Abstract
Description
本発明は、外観特性に優れた段差パイル布帛に関するものである。本発明のパイル布帛は、段差パイル布帛において、長パイル部と短パイル部、または、中パイル部と短パイル部の段差がかなり強調された外観特性に極めて優れたものであり、その結果、衣料、玩具（ぬいぐるみ等）及びインテリア用等の広範囲に新たな商品企画を可能とするものである。 The present invention relates to a step pile fabric having excellent appearance characteristics. The pile fabric of the present invention is very excellent in appearance characteristics in which the step difference between the long pile portion and the short pile portion or the middle pile portion and the short pile portion is considerably emphasized in the step pile fabric. New product planning is possible in a wide range such as for toys (stuffed animals, etc.) and interiors.
アクリル系繊維は、獣毛ライクな風合いおよび光沢を有し、ニット分野をはじめボア、ハイパイルの分野に広く使用されている。さらに、近年、これらのアクリル系繊維を用いることで、パイルの外観や風合いをより天然毛皮に近づける要望が高まってきている。元来、天然毛皮は立毛部がガードヘアー（刺し毛）とダウンへーアー（綿毛）から構成される構造を有しているのが一般的である。これにはチンチラの様に１本１本の毛の色相が系の長さ方向に変化しているもの、また、ミンクのように長くて太いガードヘアーと細くて短いダウンヘアーの２層構造となっているもの等、動物によりその特徴は様々である。このような構造をそのまま真似たものが合成繊維からなるパイル製品である。 Acrylic fibers have animal hair-like texture and luster, and are widely used in the knit field, bore and high pile fields. Furthermore, in recent years, there has been an increasing demand for using the acrylic fibers to bring the appearance and texture of the pile closer to natural fur. Naturally, natural fur generally has a structure in which a raised portion is composed of a guard hair (stabbed hair) and a down hair (fluff). This includes a chinchilla that changes the hue of each hair in the length direction of the system, and a two-layer structure consisting of a long and thick guard hair like a mink and a thin and short down hair. The characteristics vary depending on the animal. A pile product made of synthetic fibers is imitating such a structure as it is.
通常、パイル製品は、天然毛皮に近づけるために、ガードヘアー（長パイル部）を非収縮繊維で、ダウンヘアー（短パイル部）を収縮繊維で構成するのが一般的であり、長パイル部と短パイル部との段差が大きく、明確な程、外観特性に優れ、その商品性が向上する。 In general, pile products generally consist of guard hair (long pile) with non-shrinkable fibers and down hair (short pile) with shrinkable fibers in order to approach natural fur. The greater the difference between the short pile portion and the clearer, the better the appearance characteristics and the better the merchantability.
段差を大きく、明確にする技術として、アミノ基を有するオルガノポリシロキサンを繊維表面に付着してなる収縮率１５％以上を有する収縮繊維であって、収縮後の繊維−繊維間の静摩擦係数が０．２３０以下であるパイル用収縮繊維が提案されている（特許文献１）。しかしながら、この収縮繊維では、長パイル部の平均パイル長を短くすると、段差が小さくなり、外観特性に劣るという欠点があった。 As a technique for increasing and clarifying the level difference, a shrinkable fiber having a shrinkage ratio of 15% or more obtained by attaching an organopolysiloxane having an amino group to the fiber surface, and the coefficient of static friction between the fiber and the fiber after shrinkage is 0. A shrinkable fiber for piles of 230 or less has been proposed (Patent Document 1). However, in this shrink fiber, when the average pile length of the long pile portion is shortened, there is a disadvantage that the step becomes small and the appearance characteristics are inferior.
長パイル部の平均パイル長が短いパイル布帛は、近年、市場で流行しており、長パイル部の平均パイル長が短くても段差が大きく、明確な、段差パイル布帛が要求されている。しかし、短パイル部に従来の収縮繊維を用い、長パイル部の平均パイル長が短い段差パイル布帛を作成した場合、長パイル部の平均パイル長が短くなるため、プレポリッシング時の熱が収縮繊維に伝わりやすくなる。そのため、プレポリッシング時の熱で先に収縮してしまい、パイル裏面にアクリル酸エステル系接着剤を付着させ１３０℃で乾燥させる時の熱で収縮する割合が小さくなり生じる段差が小さくなる。さらに、段差が小さくなる事で、短パイル部に、ポリッシャーやブラシがあたりやすくなり、短パイル部が伸びやすくなるため、長パイル部と短パイル部の段差がさらに小さくなるといった問題が生じる。 In recent years, a pile fabric having a short average pile length in a long pile portion has been popular in the market, and even if the average pile length in a long pile portion is short, a step is large and a clear step pile fabric is required. However, when a conventional pile fiber is used for the short pile portion and a step pile fabric having a short average pile length of the long pile portion is created, the average pile length of the long pile portion is shortened, so the heat during pre-polishing is reduced. It becomes easy to be transmitted to. Therefore, it shrinks first by the heat at the time of pre-polishing, and the rate of shrinkage by the heat when the acrylic ester adhesive is attached to the back surface of the pile and dried at 130 ° C. becomes smaller and the level difference that occurs is reduced. Furthermore, since the step becomes small, the short pile portion can be easily applied with a polisher or a brush, and the short pile portion becomes easy to extend, so that the step between the long pile portion and the short pile portion becomes further small.
また、長パイル部、中パイル部及び短パイル部を有する段差パイル布帛を作成するために、特許文献２記載の収縮率が１５％以上、平均繊維長が１５〜２５mmの繊維を短パイル部に使用する技術がある。あらかじめ繊維長の短い繊維を短パイル部に用いる事で、中パイル部と段差をつける事が可能であるが、繊維長が短いために、プレポリッシング処理で捲縮が伸ばされず、プレシャーリング処理でカットされないために、段差が不明確になる。 Moreover, in order to create a step pile fabric having a long pile portion, a middle pile portion, and a short pile portion, fibers having a shrinkage ratio of 15% or more and an average fiber length of 15 to 25 mm described in Patent Document 2 are used as the short pile portion. There is technology to use. By using fibers with a short fiber length for the short pile part in advance, it is possible to make a step with the middle pile part, but because the fiber length is short, the crimping is not extended by the pre-polishing process, and the pre-shearing process Since it is not cut, the step becomes unclear.
これらの問題は、未だ解決されておらず、長パイル部の平均パイル長が短い段差パイル布帛および、長パイル部、中パイル部及び短パイル部を有する段差パイル布帛では、満足のいく物は得られていない。
本発明の目的は、長パイル部の平均パイル長が短くても、長パイル部と短パイル部に生じる段差が大きく明確な、段差パイル布帛を提供することにある。 An object of the present invention is to provide a step pile fabric in which the steps generated in the long pile portion and the short pile portion are large and clear even when the average pile length of the long pile portion is short.
すなわち、本発明の第１は、長パイル部と短パイル部を有する段差パイル布帛であって、前記、短パイル部がアクリロニトリルを３０〜４５重量％含有するアクリル系共重合体からなる繊維であり、パイル布帛の長パイル部の平均パイル長が５〜１０ｍｍであり、かつ、長パイル部と短パイル部の段差が長パイル部の平均パイル長の３５〜８０％であるパイル布帛である。 That is, the first of the present invention is a step pile fabric having a long pile portion and a short pile portion, wherein the short pile portion is a fiber made of an acrylic copolymer containing 30 to 45% by weight of acrylonitrile. The pile fabric has an average pile length of 5 to 10 mm in the long pile portion of the pile fabric, and a step difference between the long pile portion and the short pile portion of 35 to 80% of the average pile length of the long pile portion.
本発明の第２は、長パイル部と、長パイル部の平均パイル長より短い平均パイル長を有する中パイル部と、中パイル部の平均パイル長より短い平均パイル長を有する短パイル部からなる３段パイル布帛であって、前記、短パイル部がアクリロニトリルを３０〜４５重量％含有するアクリル系共重合体からなる繊維であり、長パイル部の平均パイル長が１０〜３０ｍｍであって、長パイル部と短パイル部の段差が長パイル部の平均パイル長の３５〜８０％であり、かつ中パイル部と短パイル部の段差が１ｍｍ以上あるパイル布帛である。 The second of the present invention comprises a long pile portion, a middle pile portion having an average pile length shorter than the average pile length of the long pile portion, and a short pile portion having an average pile length shorter than the average pile length of the intermediate pile portion.

New product planning is possible in a wide range such as for toys (stuffed animals, etc.) and interiors.
本発明でいうパイル部とは、パイル布帛（立毛布帛）の基布（地糸の部分）の部分を除く立毛部分を指すものであり、パイル長とは、前記の立毛部分の根本から先端までの長さをいう。長パイル部の平均パイル長とは、パイル布帛中のパイル部を構成している繊維を、毛並みが揃うように垂直に立たせ、長パイル部を構成している、繊維の根元から先端までの長さ（パイル布帛裏面からの長さではない）の測定を１０ヶ所について行った値の平均値である。また、中パイル部、短パイル部の平均パイル長も同様である。さらに、段差パイルの段差とは、上記の方法によって測定された各パイル部の平均パイル長の差である。 The pile portion in the present invention refers to a raised portion excluding the portion of the base fabric (ground yarn portion) of the pile fabric (raised fabric), and the pile length is from the root to the tip of the raised portion. The length of The average pile length of the long pile part is the length from the root to the tip of the fiber that constitutes the long pile part by making the fibers constituting the pile part in the pile fabric stand upright so as to align the fur. It is an average value of values obtained by measuring the thickness (not the length from the back of the pile fabric) at 10 locations. The same applies to the average pile length of the middle pile portion and the short pile portion. Further, the level difference of the level difference pile is a difference in average pile length of each pile portion measured by the above method.

The ratio of the long pile portion and the short pile portion of the two-stage pile fabric occupying the whole pile is preferably long pile portion / short pile portion = 10 to 90 wt% / 90 to 10 wt%. In the corrugated pile fabric, the ratio of the long pile portion, the medium pile portion, and the short pile to the whole pile is as follows: long pile portion / medium pile portion / short pile portion = 5 to 90% by weight / 5 to 90% by weight / 90 to 5% by weight is preferable.

Next to the pile part, a long (part b) shows a so-called middle hair part, and a short pile part shows the so-called down hair with the shortest pile length (part c).
本発明において、長パイル部の平均パイル長が短い２段パイル布帛とは、長パイル部の平均パイル長が１０ｍｍ以下のパイルである。 In the present invention, the two-stage pile fabric having a short average pile length in the long pile portion is a pile having an average pile length of 10 mm or less in the long pile portion.
長パイル部の平均パイル長が５ｍｍ未満では、長パイル部と短パイル部との段差が小さくなり、また、１０ｍｍ以上では段差が大きくなりすぎるために、外観特性に劣る。 If the average pile length of the long pile portion is less than 5 mm, the step difference between the long pile portion and the short pile portion becomes small, and if it is 10 mm or more, the step becomes too large, resulting in poor appearance characteristics.
本発明の２段パイル布帛において、長パイル部と短パイル部の段差は長パイル部の平均パイル長の３５〜８０％が好ましい。３５％未満では、段差が小さく外観特性に劣り、また、８０％を超えると、短パイル部が長パイル部を支えられず、立毛感に劣ったパイル布帛になる。長パイル部と短パイル部の段差は長パイル部の平均パイル長の４０〜７５％であるとさらに好ましい。 In the two-stage pile fabric of the present invention, the step difference between the long pile portion and the short pile portion is preferably 35 to 80% of the average pile length of the long pile portion. If it is less than 35%, the level difference is small and the appearance characteristics are inferior. If it exceeds 80%, the short pile part cannot support the long pile part, and the pile fabric is inferior in the feeling of napping. The step difference between the long pile portion and the short pile portion is more preferably 40 to 75% of the average pile length of the long pile portion.
本発明の３段パイル布帛において、長パイル部の平均パイル長は１０〜３０ｍｍが好ましい。長パイル部の平均パイル長が１０ｍｍ未満では、短パイル部と中パイル部の段差が小さくなり、また、３０ｍｍを超えると、短パイル部と長パイル部との段差が大きくなりすぎるため、外観特性に劣る。 In the three-stage pile fabric of the present invention, the average pile length of the long pile portion is preferably 10 to 30 mm. If the average pile length of the long pile portion is less than 10 mm, the step difference between the short pile portion and the middle pile portion becomes small. If the average pile length exceeds 30 mm, the step difference between the short pile portion and the long pile portion becomes too large. Inferior to
本発明の３段パイル布帛において、長パイル部と短パイル部の段差は長パイル部の平均パイル長の３５〜８０％である。３５％未満では短パイル部と中パイル部の段差が生じにくく外観特性に劣り、８０％を超えると、短パイル部が長パイル部を支えられず、立毛感に劣ったパイル布帛になる。長パイル部と短パイル部の段差は長パイル部の平均パイル長の４０〜７５％であるとさらに好ましい。 In the three-stage pile fabric of the present invention, the level difference between the long pile portion and the short pile portion is 35 to 80% of the average pile length of the long pile portion. If it is less than 35%, the difference in appearance between the short pile portion and the middle pile portion is unlikely to occur, and the appearance characteristics are inferior. If it exceeds 80%, the short pile portion cannot support the long pile portion, resulting in a pile fabric inferior in napping feeling. The step difference between the long pile portion and the short pile portion is more preferably 40 to 75% of the average pile length of the long pile portion.
本発明の３段パイル布帛において、中パイル部と短パイル部の段差が１ｍｍ以上である。中パイル部と短パイル部の段差が１ｍｍ未満になると、中パイル部と短パイル部の区別が付きづらく、外観特性に劣ったパイル布帛になる。 In the three-stage pile fabric of the present invention, the step between the middle pile portion and the short pile portion is 1 mm or more. When the level difference between the middle pile portion and the short pile portion is less than 1 mm, it becomes difficult to distinguish between the middle pile portion and the short pile portion, and the pile fabric is inferior in appearance characteristics.
本発明の２段パイル布帛、３段パイル布帛において、短パイル部に、収縮率が４０〜７５％の繊維を用いる事が好ましい。４０％未満では、段差が小さく外観特性に劣り、また、７５％を超えると、短パイル部が長パイル部を支えられず、立毛感に劣ったパイル布帛になる。 In the two-stage pile fabric and the three-stage pile fabric of the present invention, it is preferable to use fibers having a shrinkage of 40 to 75% in the short pile portion. If it is less than 40%, the level difference is small and the appearance characteristics are inferior. If it exceeds 75%, the short pile part cannot support the long pile part, and the pile fabric is inferior in the feeling of napping.
本発明でいう、段差パイル布帛は、長パイル部を非収縮繊維、中パイル部を収縮率１０〜４０％を有する収縮繊維、短パイル部を収縮率４０〜７５％を有する収縮繊維を用いる事で作成する事ができる。 The step pile fabric referred to in the present invention uses a non-shrinkable fiber for the long pile portion, a shrinkable fiber having a shrinkage rate of 10 to 40% for the middle pile portion, and a shrinkable fiber having a shrinkage rate of 40 to 75% for the short pile portion. Can be created.
本発明でいう、非収縮繊維とは、収縮率１０％以内の繊維である。
また、収縮率は、収縮前の繊維長をＬ０、均熱オーブン中で１３０℃、５分間収縮させた後の繊維長をＬとした時に、下記式（１）より求められる。
The non-shrinkable fiber referred to in the present invention is a fiber having a shrinkage rate of 10% or less.
Further, the shrinkage rate is obtained from the following formula (1), where L0 is the fiber length before shrinkage, and L is the fiber length after shrinkage at 130 ° C. for 5 minutes in a soaking oven.
収縮率（％）＝（Ｌ０−Ｌ）／Ｌ０…（１）
例えば、３段パイル布帛を作成する場合、短パイル部、中パイル部、長パイル部を構成する繊維を混綿し、これを通常のパイル加工により、基布の表面に植え込んでパイル部を構成し、次いで、１２０℃でプレポリッシング処理とプレシャーリング処理を行い、パイル長をそろえた後、パイル裏面にアクリル酸エステル系接着剤を付着させ、１３０℃で乾燥させる。その際に与えられる熱により、収縮繊維は収縮し、長パイル部、中パイル部、短パイル部が形成される。その後、ポリッシャー仕上げ、及びシャーリングを行い、立毛表層部のクリンプを除去することで一定長のパイル長を持つ３段パイル布帛が作成できる。
さらに、平均パイル長の短い２段パイル布帛を作成する場合、短パイル部に従来の収縮繊維を用いると、上記で述べた様に段差が明確な２段パイル布帛が得らない。しかし、短パイル部を構成する繊維に収縮率が高い３５〜８０％の収縮繊維を用いると、長パイル部の平均パイル長が短くなり、短パイル部を構成する収縮繊維にプレポリッシング時の熱が伝わり、先に収縮しても、収縮率が高い為に、パイル裏面にアクリル酸エステル系接着剤を付着させ１３０℃で乾燥させる時の熱で、さらに収縮する為、平均パイル長が短くとも、段差が明確な２段パイルを得る事ができる。
Shrinkage rate (%) = (L0−L) / L0 (1)
For example, when creating a three-stage pile fabric, the fibers constituting the short pile portion, the middle pile portion, and the long pile portion are blended, and this is implanted into the surface of the base fabric by a normal pile process to constitute the pile portion. Next, pre-polishing and pre-shearing treatments are performed at 120 ° C., and the pile lengths are aligned, and then an acrylic ester adhesive is attached to the back surface of the pile and dried at 130 ° C. Due to the heat applied at that time, the shrinkable fibers shrink and a long pile portion, a middle pile portion, and a short pile portion are formed. Then, a three-stage pile fabric having a fixed pile length can be created by performing polisher finishing and shearing, and removing the crimp on the napped surface layer portion.
Furthermore, when producing a two-stage pile fabric having a short average pile length, if a conventional shrink fiber is used for the short pile portion, a two-stage pile fabric having a clear step cannot be obtained as described above. However, when 35 to 80% of shrinkable fibers having a high shrinkage ratio are used for the fibers constituting the short pile portion, the average pile length of the long pile portion is shortened, and the heat during prepolishing is applied to the shrinkable fibers constituting the short pile portion. Even if it shrinks first, because the shrinkage rate is high, the acrylate adhesive is attached to the back of the pile and dried at 130 ° C, so it shrinks further, so even if the average pile length is short A two-stage pile with a clear step can be obtained.

The acrylic fiber constituting the short pile portion is a fiber made of an acrylic copolymer containing 20 to 60% by weight of acrylonitrile. More preferably, the amount of acrylonitrile is in the range of 30 to 45% by weight. If acrylonitrile is less than 20% by weight, the heat resistance is deteriorated and the pile processability is inferior. And a clear step pile fabric cannot be produced.
