Description

【0001】
【発明の属する技術分野】
この発明は、表地と接着して衣服を構成する接着芯地に関し、特に、水系のペーストをドット状に形成して構成されたものであって、表地等への移行低減を図り得る接着芯地に関する。
【0002】
【従来の技術】
衣服を構成するに当たり、その保型性を良好とするなどの目的で布はくの表面に接着樹脂部を備えた接着芯地が広く用いられている。この接着芯地の基本的な構造として、不織布、編布、織布等の布はくを基布に使用し、当該基布の少なくとも一方の表面側に、アイロンなどで熱圧着することで表地と接着し得る熱可塑性樹脂(ホットメルト樹脂)をドット状に形成し、接着樹脂部をそなえたものが知られている。
【0003】
上述の接着樹脂部の形成に当っては、例えばポリアミド系樹脂、ポリエステル系樹脂またはポリオレフィン系樹脂などで構成される粉末状の熱可塑性樹脂が用いられ、これら樹脂を水に分散させるための分散剤を添加して水系ペーストとし、当該ペーストを周知のプリント技術によってドット状に形成するのが一般的である。
【0004】
一方、表地には衣服とした際のまつわりつきを回避するため、帯電防止剤による加工が施されている。しかし、帯電防止処理が施されている表地では、接着芯地を接着した後、表地に部分的な濃色化を来す場合があった。このような濃色化現象の原因について、実開平4−123294号公報では、以下のような開示が為されている。即ち、この公報によれば、従前より、水系ペーストの分散剤(懸濁剤)として、低炭素数の飽和脂肪酸や不飽和脂肪酸を不純物として含む工業用ステアリン酸を主成分とするものが用いられている。従って、上記濃色化は、接着芯地側に含まれる上記不純物が表地側に移行し、これら不純物が表地側のカチオン系物質と反応して濡れ色に変色するために生じるとされている。係る要因分析に基づいて、上記公報では、ステアリン酸の純度を70%以上とし、しかも、上記不純物の含有量が5%未満の分散剤を用いた接着芯地を提供することによる濃色化の改善を提案している。
【0005】
しかしながら、所定純度のステアリン酸を主成分とする分散剤を使用した技術では、濃色化の十分な解消には至らなかった。本発明者らは、ステアリン酸以外の分散剤を種々に検討するうち、工業用ステアリン酸に含まれる不純物のみならず、ステアリン酸自体も種々のカチオン系物質と化合し、濃色化を来す原因になっているとの知見を得た。また、ステアリン酸を分散剤として用いた接着芯地により構成される、最終製品としての衣服を、例えばポリビニルアルコール(PVA)樹脂製の包装材に梱包して流通させた場合、表地の濃色化のみならず、当該包装材の内表面に白色物が付着する現象(以下、曇化と称する)も認められた。
【0006】
この明細書では上記濃色化や曇化を包括的に変色と称するが、本出願に係る発明者の実験によれば、これら変色は、表地に添加されたカルシウム成分、包装袋に添着されたナトリウム成分といった反応対象となる化合物の相違はあるが、これらカチオン成分と、ステアリン酸(その不純物を含む)との化合の結果生ずる現象であるとの結論に達した。
【0007】
上記変色を改善する技術として、本出願人は、特開平7−70926号公報に、ベヘニン酸を主成分とする分散剤の適用を提案している。
【0008】
【発明が解決しようとする課題】
上記ベヘニン酸を適用した接着芯地では、変色の解消を図ることはできるが、同一の熱可塑性樹脂をステアリン酸で分散させた水系ペーストを用いた場合に比べて、表地との接着力の点で必ずしも満足するものではなかった。
【0009】
本発明は、上述した変色及び接着力不足に鑑み、鋭意検討を重ねた結果なされたものであり、従って、本発明の目的は、表地等のカチオン系化合物との反応による変色を回避すると共に、良好な接着力を実現し得る接着芯地を提供することにある。
【0010】
【課題を解決するための手段】
この目的の達成を図るため、この出願に係る接着芯地の構成によれば、布はくの少なくとも一方の表面に、熱可塑性樹脂が分散剤によって分散された水系ペーストをドット状に被着、乾燥して形成された接着樹脂部を備えてなる接着芯地において、前述の水系ペーストに添加する分散剤の主成分を下記化学式1で表されるステアリン酸誘導体としてなることを特徴としている。
【0011】
【化1】
CH3(CH216−CO−O−(C24O)n
(但し、nは6以上10以下の整数を表す)
【0012】
また、この発明の実施に当っては、前述した水系ペーストの固形分組成を、熱可塑性樹脂と分散剤との重量の和に対して、熱可塑性樹脂65〜99重量%、前記化学式1で表される分散剤1〜35重量%とするのが好適である。
【0013】
【発明の実施の形態】
この発明の実施形態につき説明すれば、本発明の接着芯地を構成するための水系ペースト用分散剤を、ステアリン酸の水酸基末端近傍にポリエチレンオキサイド(−(C24O)n −)を導入した誘導体としている。係る構成としたことによる作用については明らかではないが、ステアリン酸に比べて、樹脂接着部として被着乾燥した後の接着性を著しく低下させることなく、昇華性が低くなるため、前述の変色を回避することができると考えられる。
【0014】
上記ステアリン酸誘導体に導入された誘導体1分子当たりのエチレンオキサイド(以下、EOと称する場合もある)の個数nは、6以上10以下、さらに好ましくは6以上9以下とするのが好適である。このnを5以下とした場合には変色の解消が難しく、11以上とした場合には、接着力の低下を生じる。
【0015】
接着芯地を構成する布はくには、従来周知の如何なるものを用いても良く、接着樹脂部を構成する主体となる熱可塑性樹脂も、ポリアミド系樹脂、ポリエステル系樹脂及びポリオレフィン系樹脂などを用いることができる。特に、熱可塑性樹脂として、アイロン接着を考慮し、融点が80〜140℃、さらに好ましくは100〜125℃のものを選択するのが良い。
【0016】
また、水系ペーストの組成は、接着に必要な熱可塑性樹脂と、これを分散してペースト化するための上記分散剤とを必須とし、これらの固形分換算の重量組成を、熱可塑性樹脂に関しては65重量%以上99重量%以下、本発明の特徴となるステアリン酸誘導体(分散剤)に関しては1重量%以上35重量%以下とすればよい。これら好適範囲は、熱可塑性樹脂と前述した一連のステアリン酸誘導体との組合せ、若しくは当該誘導体におけるEO導入の度合いにより種々に異なり、一義に定められるものではないが、これら2成分の重量組成の割合として、熱可塑性樹脂の割合が高くなれば当該樹脂の分散不足からペーストとしての安定性を欠き、分散剤の割合が高くなれば接着力の低下や接着樹脂部としての形態安定性が低下する。これら熱可塑性樹脂と分散剤の組成条件に加えて、水系ペーストを構成するに当たり、従来と同様に、アクリル酸系を始めとする増粘剤、アンモニア等のpH調整剤、或いは消泡剤などの添加剤を使用することもできる。
【0017】

以下、この出願に係る発明の実施例につき説明する。尚、以下の実施例では、説明を理解し得る程度の特定条件を例示して説明するが、この発明は、これら特定条件にのみ限定されるものではなく、発明の目的の範囲内で任意好適に設計の変更及び変形を行い得る。

BACKGROUND OF THE INVENTION
The present invention relates to an adhesive interlining that is bonded to a surface material to form a garment, and in particular, is formed by forming a water-based paste in the form of dots, and can be used to reduce the transition to the surface material. About.
[0002]
[Prior art]
In constituting clothes, an adhesive interlining having an adhesive resin portion on the surface of a cloth sheet is widely used for the purpose of improving its shape retention. As a basic structure of this adhesive interlining, a cloth such as non-woven fabric, knitted fabric, woven fabric, etc. is used for the base fabric, and the surface of the base fabric is thermocompression-bonded with an iron or the like on at least one surface side of the base fabric. It is known that a thermoplastic resin (hot melt resin) that can be bonded to the substrate is formed in a dot shape and has an adhesive resin portion.
[0003]
In forming the above-mentioned adhesive resin portion, for example, a powdery thermoplastic resin composed of a polyamide resin, a polyester resin, or a polyolefin resin is used, and a dispersant for dispersing these resins in water. In general, an aqueous paste is added, and the paste is formed into dots by a well-known printing technique.
[0004]
On the other hand, the outer surface is processed with an antistatic agent in order to avoid flickering when used as clothing. However, in the case of the outer surface subjected to the antistatic treatment, after the adhesive interlining is bonded, there is a case where the surface is partially darkened. Regarding the cause of such a darkening phenomenon, the following disclosure is made in Japanese Utility Model Laid-Open No. 4-123294. That is, according to this publication, as a dispersant (suspension) for an aqueous paste, a paste mainly composed of industrial stearic acid containing a saturated fatty acid having a low carbon number or an unsaturated fatty acid as an impurity is used. ing. Therefore, the darkening is said to occur because the impurities contained on the adhesive core side migrate to the surface side, and these impurities react with the cationic material on the surface side and change to a wet color. Based on such factor analysis, in the above publication, the purity of stearic acid is set to 70% or more, and moreover, by providing an adhesive interlining using a dispersant having the impurity content of less than 5%, Suggest improvements.
[0005]
However, the technique using a dispersant mainly composed of stearic acid having a predetermined purity has not resulted in sufficient elimination of darkening. As the inventors of the present invention have studied various dispersants other than stearic acid, not only impurities contained in industrial stearic acid but also stearic acid itself combines with various cationic substances, resulting in darkening. I got the knowledge that it was the cause. In addition, when clothing as the final product, which is composed of an adhesive interlining using stearic acid as a dispersant, is packaged and distributed in, for example, a packaging material made of polyvinyl alcohol (PVA) resin, the surface is darkened. In addition, a phenomenon (hereinafter referred to as clouding) in which a white substance adheres to the inner surface of the packaging material was also observed.
[0006]
In this specification, the above-described darkening and clouding are collectively referred to as discoloration. However, according to the inventors' experiments according to the present application, these discolorations were attached to the calcium component added to the outer fabric and the packaging bag. Although there are differences in the compounds to be reacted, such as the sodium component, it has been concluded that this is a phenomenon resulting from the combination of these cationic components with stearic acid (including its impurities).
[0007]
As a technique for improving the discoloration, the present applicant has proposed the application of a dispersant containing behenic acid as a main component in JP-A-7-70926.
[0008]
[Problems to be solved by the invention]
The adhesive interlining applied with the above-mentioned behenic acid can eliminate discoloration, but compared to the case where an aqueous paste in which the same thermoplastic resin is dispersed with stearic acid is used, the adhesive strength with the outer surface is increased. It was not always satisfactory.
[0009]
The present invention has been made as a result of intensive studies in view of the above-described discoloration and insufficient adhesive force. Therefore, the object of the present invention is to avoid discoloration due to reaction with a cationic compound such as a surface material, An object of the present invention is to provide an adhesive interlining capable of realizing a good adhesive force.
[0010]
[Means for Solving the Problems]
In order to achieve this object, according to the configuration of the adhesive interlining according to this application, a water-based paste in which a thermoplastic resin is dispersed by a dispersant is applied to at least one surface of a cloth foil in a dot shape. In an adhesive interlining comprising an adhesive resin portion formed by drying, the main component of the dispersant added to the aqueous paste is a stearic acid derivative represented by the following chemical formula 1.
[0011]
[Chemical 1]
CH 3 (CH 2) 16 -CO -O- (C 2 H 4 O) n H
(However, n represents an integer from 6 to 10.)
[0012]
In the practice of the present invention, the solid content composition of the aqueous paste described above is represented by 65 to 99% by weight of the thermoplastic resin with respect to the sum of the weights of the thermoplastic resin and the dispersant represented by the chemical formula 1. It is preferable that the dispersant is 1 to 35% by weight.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described. An aqueous paste dispersant for constituting the adhesive interlining according to the present invention is obtained by using polyethylene oxide (— (C 2 H 4 O) n —) in the vicinity of the hydroxyl terminal of stearic acid. Introduced derivatives. Although it is not clear about the effect of having such a structure, sublimation is reduced without significantly reducing the adhesion after drying as a resin adhesive compared to stearic acid. It can be avoided.
[0014]
The number n of ethylene oxide (hereinafter also referred to as EO) per molecule of the derivative introduced into the stearic acid derivative is preferably 6 or more and 10 or less, more preferably 6 or more and 9 or less. When n is 5 or less, it is difficult to eliminate discoloration, and when it is 11 or more, the adhesive strength is reduced.
[0015]
Any conventionally known cloth may be used to form the adhesive interlining, and the main thermoplastic resin constituting the adhesive resin portion is a polyamide resin, a polyester resin, a polyolefin resin, or the like. be able to. In particular, it is preferable to select a thermoplastic resin having a melting point of 80 to 140 ° C., more preferably 100 to 125 ° C. in consideration of iron adhesion.
[0016]
In addition, the composition of the water-based paste includes the thermoplastic resin necessary for adhesion and the dispersant for dispersing the paste to form a paste, and the weight composition in terms of solid content is related to the thermoplastic resin. With respect to the stearic acid derivative (dispersing agent) that is a feature of the present invention, it may be 1% by weight or more and 35% by weight or less. These preferred ranges vary depending on the combination of the thermoplastic resin and the series of stearic acid derivatives described above, or the degree of EO introduction in the derivatives, and are not uniquely defined, but the ratio of the weight composition of these two components If the ratio of the thermoplastic resin is high, the stability of the paste is lacking due to insufficient dispersion of the resin, and if the ratio of the dispersant is high, the adhesive strength and the form stability as the adhesive resin part are reduced. In addition to the composition conditions of these thermoplastic resins and dispersants, when constituting an aqueous paste, as in the past, thickeners such as acrylic acid, pH adjusters such as ammonia, or antifoaming agents, etc. Additives can also be used.
[0017]

However, clear discoloration was recognized in the adhesive interlining produced using stearic acid (Comparative Example 1).
[0032]
In addition, as a result of the adhesion test, the adhesive interlinings of Examples 1 to 4 in which the EO of the stearic acid derivative was configured to be 6 to 10 were all the adhesive interlinings using behenic acid (Comparative Example 4). Compared with, the adhesive strength could be improved.
[0033]
From the evaluation of the discoloration and the adhesive strength, it can be understood that an excellent adhesive interlining can be realized by setting the EO of the stearic acid derivative in the range of 6 to 10 (Examples 1 to 4). .
[0034]
【The invention's effect】
As is clear from the above description, according to the configuration of the adhesive interlining of the present invention, at least one surface of the cloth foil is coated with a water-based paste in which a thermoplastic resin is dispersed by a dispersant in the form of dots. In an adhesive core comprising an adhesive resin portion formed by drying, the main component of the dispersant added to the aqueous paste is a stearic acid derivative represented by the chemical formula 1. For this reason, while avoiding discoloration by reaction with cationic compounds, such as a surface material, the adhesive interlining which can implement | achieve favorable adhesive force can be provided.
