Description

本発明は、接着剤でコーティングされた繊維担体から構成され、刺繍接着芯地として使用される芯地であって、前記接着剤は水溶性の熱可塑性ポリマーを有している芯地に関する。   The present invention relates to an interlining made of a fiber carrier coated with an adhesive and used as an embroidery adhesive interlining, wherein the adhesive has a water-soluble thermoplastic polymer.

冒頭に述べたタイプの水溶性刺繍接着芯地のための水溶性接着剤はすでにドイツ特許公開公報第１００３２７９６号明細書から公知である。さらに、芯地、特に不織布への繊維層の一時的固着に使用される固着性水溶性接着剤も公知である。   A water-soluble adhesive for water-soluble embroidery adhesive interlinings of the type mentioned at the outset is already known from DE 100 32 996 A1. Furthermore, an adhesive water-soluble adhesive used for temporarily fixing a fiber layer to an interlining, particularly a nonwoven fabric, is also known.

この場合、加工前または加工中に、芯地ないし不織布は上地として形成された繊維層と熱プレスによって貼り合わされる。これに続いて、強化層および非強化層が組み合わされ、縫い付けられて、必要に応じ、成形アイロンによって成形される。   In this case, before or during processing, the interlining or non-woven fabric is bonded to the fiber layer formed as an upper layer by hot pressing. Following this, the reinforced and non-reinforced layers are combined, sewn and, if necessary, molded with a shaped iron.

続いての洗浄工程の後、接着剤は洗い流される。これによって、組み合わされた層は再び溶解され、こうして、衣類はいっそう柔軟かつソフトになる。   After the subsequent washing step, the adhesive is washed away. This re-melts the combined layers, thus making the garment more flexible and soft.

こうして、収縮性の相違するクロスも、保護処理後に気泡形成を生ずることなく、組み合わせることが可能である。   Thus, cloths having different shrinkages can be combined without forming bubbles after the protective treatment.

ドイツ特許公開公報第１００３２７６９号明細書から公知の接着剤は、スプレッドコーティング、ホットメルトコーティング、水溶性溶融接着剤不織布の重ね合わせまたは水溶性不織布上への溶融接着剤不織布の直接の精紡によって付着する。   The adhesives known from German Offenlegungsschrift 100 32 769 are applied by spread coating, hot melt coating, superposition of water-soluble melt-adhesive nonwovens or direct spinning of melt-adhesive nonwovens on water-soluble nonwovens. To do.

ドイツ特許公開第１００３２７６９号明細書から公知のコポリアミド／ポリアミド、ポリビニルアルコールおよび／またはコポリアミド／ポリアミド・ベースの接着剤用ポリマーは、接着剤中の水分が水溶性不織布の点状溶解をもたらすことから、水性分散液の形でロータリースクリーン印刷法によって水溶性不織布上にプリントすることは不可能である。   The copolyamide / polyamide, polyvinyl alcohol and / or copolyamide / polyamide based adhesive polymers known from DE 10032769 have a water content in the adhesive that causes point-like dissolution of the water-soluble nonwoven fabric. Therefore, it is impossible to print on a water-soluble nonwoven fabric by the rotary screen printing method in the form of an aqueous dispersion.

水溶性不織布の溶けたあるいはプリントされた箇所が、接着剤でコーティングされた不織布に対して見栄えのよくない印象を感じさせてしまう表面性状を作り出す。   The melted or printed portion of the water-soluble nonwoven fabric creates a surface texture that makes the nonwoven fabric coated with the adhesive feel an unsightly impression.

このような懸念は芯地が接着した繊維層にも生じるので、この表面性状に対する懸念が完成品の視覚的印象を損なうという好ましくない現象を生み出してしまうことになる。   Such a concern also occurs in the fiber layer to which the interlining is bonded, so that the concern about the surface property creates an undesirable phenomenon that the visual impression of the finished product is impaired.

不織布中の溶けた箇所もしくは穴は許容できないものであるので、そのようなものの衣類または刺繍用の材料としての使用は不可能である。   Since the melted points or holes in the nonwoven fabric are unacceptable, they cannot be used as clothing or embroidery materials.

ドイツ特許公開公報第１００３２７６９号明細書German Patent Publication No. 10032769

そこで本発明の目的は、従来の技術から公知の接着剤を、水溶性芯地とくに不織布に問題なく使用できるよう改良することである。   Accordingly, an object of the present invention is to improve an adhesive known from the prior art so that it can be used without any problem for a water-soluble interlining, particularly a nonwoven fabric.

本発明は上記課題を特許請求項１記載の特徴によって解決する。   The present invention solves the above problems by the features of claim 1.

この請求項による特徴は、冒頭に述べたタイプの芯地において、接着剤が水性ポリマー分散液またはポリマー溶液あるいはその両方として形成されていること、接着剤がポリビニルアセテート成分を有するビニルピロリドンとポリエチレングリコールとの混合物を有し、該混合物中のポリエチレングリコールの含有量が３〜１５％であること、繊維担体及び接着剤がいずれも１０〜４０℃の温度で水溶性となること、接着剤が５０％以上の固体含有量を有することである。 The features according to this claim are characterized in that, in an interlining of the type mentioned at the outset , the adhesive is formed as an aqueous polymer dispersion and / or a polymer solution, and the vinylpyrrolidone and polyethylene glycol having a polyvinyl acetate component. The content of polyethylene glycol in the mixture is 3 to 15%, the fiber carrier and the adhesive are both water-soluble at a temperature of 10 to 40 ° C., and the adhesive is 50 % Solid content .

驚くべきことに、十分高度に濃縮された水性ポリマー分散液またはポリマー溶液あるいはその両方は、上述した不適な効果を生ずることなく、易水溶性支持体上にプリント可能であることが見出された。本発明により、水性系が冷水可溶性不織布にプリント可能であることが見出された。ここでは、冷水とは温度４０℃以下の水として理解される。
また、ビニルピロリドンは冷水可溶性に優れているが、強い吸湿性を有し、空気湿度が高まると共に粘着性が増大するのに対し、ポリビニルアセテート成分を有するビニルピロリドンは室温において非改質ビニルピロリドンほど強い吸湿性を有していないため、接着剤がポリビニルアセテート成分を有するビニルピロリドンを有することで、コーティングされた芯地が巻き付けられた状態で互いに付着してしまうことが回避される。
また、接着剤がポリエチレングリコール（ＰＥＧ）を所定の割合で有するため、ビニルピロリドンの融解範囲を変化とりわけ低下させ、あるいは、ポリマーのメルトフローをそれぞれの使用に適合させることが可能となる。水溶性接着剤はポリエチレングリコールによって軟化される。特に好ましくは、ＰＥＧ４００が０〜２０％の濃度にて、特に好ましくは２〜１０％の濃度で使用される。
また、繊維担体が水溶性であるため、支持体を溶解させることができる。
また、繊維担体および接着剤はいずれも１０〜４０℃の温度で水に溶ける、水溶性であるため、好都合である。
また、接着剤の固体含有量が５０％以上であるため、冷水可溶性支持体の膨潤が回避される。 Surprisingly, it has been found that sufficiently highly concentrated aqueous polymer dispersions and / or polymer solutions can be printed on easily water-soluble supports without producing the above-mentioned unfavorable effects. . In accordance with the present invention, it has been found that aqueous systems can be printed on cold water soluble nonwovens. Here, cold water is understood as water having a temperature of 40 ° C. or lower.
Vinylpyrrolidone is excellent in cold water solubility, but has strong hygroscopicity, and the air humidity increases and the tackiness increases. Since it does not have strong hygroscopicity, it is avoided that the adhesive has vinyl pyrrolidone having a polyvinyl acetate component, so that the coated interlining adheres to each other in a wound state.
In addition, since the adhesive has polyethylene glycol (PEG) in a predetermined ratio, it becomes possible to change the melting range of vinylpyrrolidone, particularly to reduce the polymer melt flow, or to adapt it to each use. The water-soluble adhesive is softened with polyethylene glycol. Particularly preferably, PEG 400 is used at a concentration of 0 to 20%, particularly preferably at a concentration of 2 to 10%.
Moreover, since the fiber carrier is water-soluble, the support can be dissolved.
Moreover, since both the fiber carrier and the adhesive are soluble in water at a temperature of 10 to 40 ° C., they are advantageous.
Moreover, since the solid content of the adhesive is 50% or more, swelling of the cold water soluble support is avoided.

上記課題はさらに以下のようにしてより良好に解決される。   The above-mentioned problem can be solved better as follows.

プリントに際してはＣＰ５〜ＣＰ２５０のステンシルサイズを使用することができる。   For printing, a stencil size of CP5 to CP250 can be used.

さらに、接着剤には、０〜１０重量％のプリント助剤たとえば分散剤または増粘剤が混入されると好適である。   Further, it is preferable that 0 to 10% by weight of a printing aid such as a dispersant or a thickener is mixed in the adhesive.

繊維担体はポリビニルアルコールから製造されていることが好適である。支持体のポリビニルアルコールはポリマーのエトキシ化または鹸化度９５％以上の鹸化によって改質されているとよい。改質されたポリビニルアルコールは冷水つまり１０〜４０℃の温度の水によく溶解する。特に、繊維担体は不織布として形成されていることが好都合である。この不織布は２０〜１２０ｇ／ｍ２の単位面積重量を有しているとよい。 The fiber carrier is preferably made from polyvinyl alcohol. The polyvinyl alcohol of the support is preferably modified by ethoxylation of the polymer or saponification with a saponification degree of 95% or more. The modified polyvinyl alcohol dissolves well in cold water, that is, water having a temperature of 10 to 40 ° C. In particular, the fiber carrier is advantageously formed as a non-woven fabric. The nonwoven fabric preferably has a unit area weight of 20 to 120 g / m 2 .

冒頭に述べた課題は、繊維担体をコーティングするための接着剤であって、水性ポリマー分散液またはポリマー溶液あるいはその両方を含み、５０％以上の固体含有量を有するとともに、ポリビニルアセテート成分を有するビニルピロリドンとポリエチレングリコールとの混合物を有し、前記混合物中の前記ポリエチレングリコールの含有量が３〜１５％であり、前記繊維担体及び前記接着剤がいずれも１０〜４０℃の温度で水溶性となる接着剤によっても解決できる。 The problem mentioned at the beginning is an adhesive for coating a fiber carrier , comprising an aqueous polymer dispersion and / or a polymer solution, having a solids content of 50% or more and having a polyvinyl acetate component It has a mixture of pyrrolidone and polyethylene glycol, the polyethylene glycol content in the mixture is 3 to 15%, and the fiber carrier and the adhesive are both water-soluble at a temperature of 10 to 40 ° C. It can also be solved with an adhesive .

上記の接着剤は非水溶性支持体へのプリントにも適している。非水溶性の繊維担体にも、加工後に容易に洗い流すことのできる上記接着剤による良好な固着性コートを付着させることが可能である。 The above adhesive is also suitable for printing on a water-insoluble support. It is also possible to attach a good adhesive coat with the above-mentioned adhesive that can be easily washed away after processing to a water-insoluble fiber carrier .

本願明細書に述べる芯地は固着性を有している。すなわち、この芯地は、熱処理によって、任意の類の繊維製上地と問題なく結合可能である。こうした熱処理つまり固着または貼り合せは８０〜１４０℃の温度にて実施される。   The interlining described in the present specification has adhesiveness. That is, the interlining can be bonded to any kind of fiber upper without any problem by heat treatment. Such heat treatment, that is, fixing or bonding is performed at a temperature of 80 to 140 ° C.

本願明細書に述べる接着剤は、好ましくは、不織布芯地とくに水溶性の不織布芯地および／または刺繍不織布に使用可能である。   The adhesives described herein are preferably usable for nonwoven fabrics, especially water soluble nonwoven fabrics and / or embroidery nonwovens.

本願明細書に述べるタイプの芯地を製造するための本発明による方法は、前記繊維担体を準備するステップと、水性ポリマー分散液またはポリマー溶液あるいはその両方を有する接着剤で前記繊維担体をコーティングするステップとを含み、前記接着剤がポリビニルアセテート成分を有するビニルピロリドンとポリエチレングリコールとの混合物を有するとともに、５０％以上の固体含有量を有し、前記混合物中の前記ポリエチレングリコールの含有量が３〜１５％であり、前記繊維担体及び前記接着剤がいずれも１０〜４０℃の温度で水溶性となることである。これによれば、先ず、水性ポリマー分散液またはポリマー溶液あるいはその両方でコーティングされた中間製品として芯地が製造される。この中間製品は、続いて、水性ポリマー分散液またはポリマー溶液あるいはその両方の水分が除去され、最終製品つまり本願で特許請求されている芯地となる。 The method according to the invention for producing an interlining of the type described herein comprises the steps of preparing the fiber carrier and coating the fiber carrier with an adhesive having an aqueous polymer dispersion and / or a polymer solution. and a step seen including, together with a mixture of vinyl pyrrolidone and polyethylene glycol, wherein the adhesive has a polyvinyl acetate component has a solids content of 50% or more, the content of the polyethylene glycol in said mixture is 3 The fiber carrier and the adhesive are both water-soluble at a temperature of 10 to 40 ° C. According to this, an interlining is first produced as an intermediate product coated with an aqueous polymer dispersion or a polymer solution or both. This intermediate product is subsequently dehydrated of the aqueous polymer dispersion and / or the polymer solution, resulting in the final product, the core claimed herein.

さて、本発明の技術思想を好適な形態で実現し、発展させるさまざまな可能性が存在する。これについては、従属請求項にも記載されているし、さらに以下に記載の好ましい実施形態の説明を参照することができる。   There are various possibilities for realizing and developing the technical idea of the present invention in a suitable form.

上記第２表に挙げられた改質（ｍｏｄ．）ＰＡ（ポリアミド）はドイツ公開第１００ ３２ ７６９号記載の実施例１によるポリアミドと同じである。ＶＡはビニルアセテートの略であり、その際、製品Ｌｕｖｉｔｅｃ ＶＡ ６４が使用される。ＰＥＧはポリエチレングリコールの略である。   The modified (mod.) PA (polyamide) listed in Table 2 above is the same as the polyamide according to Example 1 described in German Offenlegungsschrift 100 32 769. VA is an abbreviation for vinyl acetate, in which case the product Luvitec VA 64 is used. PEG is an abbreviation for polyethylene glycol.

利点：
コポリエステル・ベースの冷水可溶性ポリマー粉末（タイプＳｃｈａｅｔｔｉｆｉｘ ６９９）の焼結に際する焼結条件は支持体の収縮開始限度の１５０℃以上であった。焼結時には大きな幅損失が生じた。 advantage:
The sintering conditions for the sintering of the copolyester-based cold water soluble polymer powder (type Schaettifix 699) were 150 ° C. or more, the limit of shrinkage of the support. A large width loss occurred during sintering.

上記は、本発明による混合物と本願明細書に述べる方法をもってすれば、もはや問題ではない。１５０℃以下の乾燥温度は十分に実現可能である。プリントされた点の焼結は非常に良好である。   The above is no longer a problem with the mixture according to the invention and the method described herein. A drying temperature of 150 ° C. or lower is sufficiently realizable. The sintering of the printed spot is very good.

水溶性ポリマーから紡糸不織布を別個に精紡し、これらを水溶性不織布と貼り合せるという手間とコストを要する方法は、本願明細書に述べる方法によって大幅に簡易化される。   A method requiring labor and cost of separately spinning a spun nonwoven fabric from a water-soluble polymer and bonding them to the water-soluble nonwoven fabric is greatly simplified by the method described in the present specification.

上記のタイプのポリマー混合物も融合させることが可能であるが、その際、褐色気味の変色が生ずる。このポリマー混合物はホットメルトとしてまたは微粉砕された状態で粉末点として付着可能である。ただし、こうした付加的な工程は方法コストを高め、しかも、変色は望ましくない付加的な性状をもたらすことになる。   It is also possible to fuse polymer mixtures of the above type, but this results in a brownish discoloration. The polymer mixture can be deposited as a hot melt or as a powder spot in the finely divided state. However, these additional steps increase process costs and discoloration can lead to undesirable additional properties.

本願明細書に述べる方法は、成分を攪拌混合することができるため、容易に実現可能である。脱気後、やや白みがかった分散液または透明な溶液が生ずる。変性セルロースからなる１〜３％の増粘剤によって、混合物の粘度をプリントに必要な粘度に調整することが可能である。また、必要に応じ、なおその他のプリント助剤をわずかな量で添加することも可能である。   The method described in the present specification can be easily realized because the components can be stirred and mixed. After degassing, a slightly whitish dispersion or clear solution is formed. It is possible to adjust the viscosity of the mixture to that required for printing with a 1 to 3% thickener made of modified cellulose. If necessary, other printing aids can be added in a small amount.

プリント可能な接着剤は、冷水可溶性支持体への良好なプリントを可能にすべく、５０％以上の固体含有量を有していなければならない。ただし、固体含有量が７５％以上になると、プリントへの使用がなかなか困難になる高粘度の混合物が生ずる。非水溶性支持体には、固体含有量のもっと低い混合物もプリント可能である。   The printable adhesive must have a solids content of 50% or more to allow good printing on cold water soluble substrates. However, when the solid content is 75% or more, a high-viscosity mixture is produced that is difficult to use for printing. It is also possible to print a mixture with a lower solid content on the water-insoluble support.

本発明による理論のさらにその他の有利な実施態様ならびに発展形態については、一方で本願明細書の一般的な記述を、他方で添付の特許請求の範囲を参照されたい。   For further advantageous embodiments and developments of the theory according to the invention, reference is made, on the one hand, to the general description herein and, on the other hand, to the appended claims.

最後に、上述したように、ここで取り上げられた実施形態ないしは実施例は本発明の技術思想の説明を目的としたものであり、本発明がこれらの実施形態ないしは実施例に限定されるものではないことを、特に強調しておく。   Finally, as described above, the embodiments or examples taken up here are for the purpose of explaining the technical idea of the present invention, and the present invention is not limited to these embodiments or examples. Emphasize that there is nothing.
