Description

【0001】
【発明の属する技術分野】
本発明は改善された制電耐久性と深色性を合わせて持つポリエステル繊維布帛に関する。
【0002】
【従来の技術】
従来、制電性と制電性以外の他の機能、例えば撥水性の両方の機能を合わせ持つポリエステル繊維布帛を得る方法として、制電剤と撥水剤を併用する方法が広く知られている。
【0003】
例えば特開昭55−148281号公報には、側鎖にパーフルオロアルキル基をもつ含フッ素化合物と、ポリアルキレンオキサイド系化合物のアクリレート及び/またはメタクリレートを混合し、布帛に付着させた後重合させて、該布帛表面に両重合体の混合皮膜を形成する方法が開示されている。
【0004】
しかしながら、制電剤と他の機能剤を併用した場合、一般に制電剤は親水性の性質が強いために、他の機能剤の機能を低下させ、両方の機能を維持させることは困難であった。
【0005】
つまり、上記公報の方法においては、一時的に撥水性能と制電性能の機能を両立できることがあっても、洗濯あるいはドライクリーニングを多数回繰り返して行なった場合には、制電性能が著しく低下してしまうのが実情であった。
【0006】
このような問題を解決するため、本発明者らは先に、ポリエステル繊維布帛に制電剤(ハイドロゲル)と撥水剤の両層を独立して形成させ、しかもその際、制電剤層の少なくとも一部を撥水剤層で被覆することにより、制電性と撥水性を両立させ、しかもその耐久性を向上させることを提案した。
【0007】
上記方法によれば、制電性と、撥水性以外の他の機能を両立させることも可能となると予測されるが、本発明者らの検討によれば、撥水剤に代えてある種の深色化剤を使用した場合には、やはり制電性能が低下してしまう場合があるということが判明した。
【0008】
【発明が解決しようとする課題】
本発明の目的は上記従来技術の有する問題を解消し、改善された制電耐久性と深色性を合わせ持つポリエステル繊維布帛及びその製造方法を提供することにある。
【0009】
【課題を解決するための手段】
本発明者らは上記目的を達成するため鋭意検討した結果、ボリエステル繊維布帛に制電能を有する反応性ウレタン重合体と深色性重合体(以下単に深色化剤という場合がある)の両層を独立して形成させしかもその際、反応性ウレタン重合体層の一部を深色化剤層で被覆するとき、所望の布帛が得られることを究明した。
【0010】
即ち、本発明によれば、深色化剤が混在しない、制電能を有する反応性ウレタン重合体皮膜が固着されたポリエステル繊維から主として構成された布帛であって、該反応性ウレタン重合体皮膜の少なくとも一部は、パーフルオロアルキル基を含有する反応性化合物から形成された重合体であり、かつ制電剤が混在しない深色化剤で被覆されており、洗濯10回後の深色度△L*値が0.5以上、且つ洗濯10回後の摩擦帯電圧が1.5KV以下であることを特徴とする制電耐久性の改善された深色性ポリエステル繊維布帛が提供される。
【0011】
また、本発明によれば、主としてポリエステル繊維から構成された布帛に、深色化剤が混在しない、制電能を有する反応性ウレタン重合体皮膜を固着させた後、さらに該反応性ウレタン重合体皮膜上に、パーフルオロアルキル基を含有する反応性化合物から形成された重合体であり、かつ制電剤が混在しない深色化剤の皮膜を形成させることを特徴とする制電耐久性の改善された深色性ポリエステル繊維布帛の製造方法が提供される。
【0012】
【発明の実施の形態】
本発明に使用する、主としてポリエステル繊維から構成される布帛とは、ポリエステル繊維のみを使用した織編物、不織布はもとより、ポリエステル繊維とナイロン繊維の混用品、ポリエステル繊維と綿の混用品、ポリエステル繊維とウールの混用品、ボリエステル繊維とレーヨン等の混用品など、ポリエステル繊維を50%以上含むものを言う。
【0013】
本発明で使用する反応性ウレタン重合体は、制電性能を有するものであり、20℃の水中に24時間浸漬した後の水に対する溶解度が20%以下のものが好ましい。
【0014】
上記の水に対する溶解度が20%を超える重合体を用いた場合は、後述のソーピングを行なった時、重合体の脱落量が多すぎて制電効果が奏されない場合がある。
【0015】
また、本発明で使用する深色化剤は、パーフルオロアルキル基を含有する反応性化合物などが好ましく例示され、具体的には下記一般式で表わされる反応性化合物があげられる。
【0016】
【化3】

Figure 0003759240
【0017】
式中、Rは水素又は低級アルキル基、Rf はCm F2m+1で表されるパーフルオロアルキル基と、水酸基、エステル基、アミノ基及び不飽和アルキル基から選ばれた少なくとも一種の基とを含む基を現わし、mは2〜21の整数、または、10〜200の整数を示す。
【0018】
上記の重合体は、2種類以上の重合体からなる共重合体、あるいは上記重合体と上記重合体以外の重合性化合物、例えば、アクリル酸、メタクリル酸、スチレン、塩化ビニルなどのビニル系化合物との共重合体の形で使用されても良く、アクリル系化合物、酢酸ビニル系化合物、メラニン系化合物などをブレンドしたものでもかまわない。
【0019】
また、深色性能の耐久性を高める目的で、上記重合体と共に下記式で示される多官能アジリジン化合物を併用してもかまわない。
【0020】
【化4】
Figure 0003759240
【0021】
(ただし、Rは水素又はメチル基をあらわす。)
【0022】
本発明の布帛は、制電能を有する反応性ウレタン重合体皮膜が固着されたポリエステル繊維から主として構成され、且つ該反応性ウレタン重合体皮膜の一部は深色化剤で被覆されていることが必要である。
【0023】
ここで、反応性ウレタン重合体皮膜が固着されたポリエステル繊維とは、前述の反応性ウレタン重合体を形成可能な化合物を含浸した後、乾燥及びキュアして重合体皮膜を固着形成させた単繊維又はヤーンを言う。
【0024】
つまり、本発明の布帛においては、繊維に固着された反応性ウレタン重合体層と、該反応性ウレタン重合体層を被覆する深色化層の2つの層が独立して存在しているので、それぞれの剤が充分に機能を発現することができる。
【0025】
上記のような布帛を製造する具体的な方法としては、先ず、ポリエステル繊維布帛にパッド法、コーティング法あるいはスプレー法などにより、反応性ウレタン重合体を形成可能な化合物を含浸付着させ、乾燥後キュアリングして繊維に重合体皮膜を固着させる。
【0026】
この際、反応性ウレタン重合体は深色化剤が混在しないものを用いる必要がある。また、乾燥条件は100〜130℃で1〜5分、また、キュアリング条件は150〜180℃で1〜3分が好ましく採用される。
【0027】
次いで、上記布帛に、パーフルオロアルキル基を含有する反応性化合物を形成可能な化合物などをパッド法、コーティング法あるいはスプレー法などにより含浸付着させ、乾燥後キュアリングを行なえば、反応性ウレタン重合体皮膜を深色化剤で被覆することができる。
【0028】
この際、深色化剤は制電剤が混在しないものを用いる必要がある。また、乾燥条件及びキュアリングの条件は、反応性ウレタン重合体の場合と同じ条件を採用すれば良い。
【0029】
さらに、反応性ウレタン重合体皮膜の固着後、深色化剤の含浸付着に先立ち、40〜80℃の熱水中で10〜20分間ソーピングを行なうことが好ましい。
【0030】
ソーピングを行なうことにより、過剰の反応性ウレタン重合体が除去されるので、深色化剤で被覆した際に、前述の独立層が形成され易くなり、本発明の効果が顕著に発現する。
【0031】
かくして得られたポリエステル繊維布帛は、良好な深色性を有している上、制電性の耐久性が格段に向上しており、10回の洗濯後においても、△L*値の差が0.5以上と言う高い深色性と、摩擦帯電圧が、1.5KV以下と言う良好な制電性を維持している。
【0032】
【作用】
従来の、制電剤と深色化剤とを混合して付着させた布帛の場合、制電剤は親水性の性質が強いために深色化剤の機能を低下させ、しかも洗濯等で容易に脱落が起こるので、両方の剤が互いに相殺し合い、制電性、深色性いずれの機能も充分に発現せず、耐久性の劣る布帛しか得られなかった。
【0033】
これに対して本発明のポリエステル繊維布帛は、繊維に固着された反応性ウレタン重合体皮膜と、該反応性ウレタン重合体皮膜を被覆する深色化剤層の2つの層が独立して存在しているので、それぞれの剤が充分に機能を発現することができる上、洗濯等による反応性ウレタン重合体の脱落が防止でき、制電性能の耐久性が格段に向上できる。
【0034】
その理由の詳細については明確ではないが、前述のような方法で布帛に反応性ウレタン重合体皮膜と深色化剤層を形成させた時、微視的に見れば繊維表面に反応性ウレタン重合体皮膜のみが固着された部分(海)と該反応性ウレタン重合体皮膜がさらに深色化剤層で被覆された部分(島)が海島状に形成され、前者が主として制電防止効果を、また後者が主として反応性ウレタン重合体の脱落防止効果を呈すると共に、巨視的に見た時の深色性は島部の深色化剤層が効果を発現するものと推定される。
【0035】

本発明によれば、洗濯に対する耐久性が改良された制電性能と、良好な深色性能を併せ持つポリエステル繊維布帛が得られ、一般衣料用途はもとより、各種スポーツ衣料用途等に幅広く使用することができる。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a polyester fiber fabric having improved antistatic durability and deep colorability.
[0002]
[Prior art]
Conventionally, as a method for obtaining a polyester fiber fabric having both antistatic properties and other functions other than antistatic properties, for example, water repellent functions, a method of using an antistatic agent and a water repellent in combination is widely known. .
[0003]
For example, in Japanese Patent Application Laid-Open No. 55-148281, a fluorine-containing compound having a perfluoroalkyl group in a side chain and a polyalkylene oxide compound acrylate and / or methacrylate are mixed, adhered to a fabric, and then polymerized. A method of forming a mixed film of both polymers on the surface of the fabric is disclosed.
[0004]
However, when antistatic agents are used in combination with other functional agents, the antistatic agents generally have strong hydrophilic properties, so it is difficult to reduce the functions of other functional agents and maintain both functions. It was.
[0005]
In other words, in the method described in the above publication, even if the functions of water repellency and antistatic performance can be temporarily achieved, the antistatic performance is significantly reduced when washing or dry cleaning is repeated many times. It was the actual situation.
[0006]
In order to solve such a problem, the present inventors first formed an antistatic agent (hydrogel) and a water repellent layer independently on a polyester fiber fabric, and in that case, the antistatic agent layer It was proposed that at least a part of the coating is covered with a water repellent layer to achieve both antistatic properties and water repellency, and to improve its durability.
[0007]
According to the above method, it is predicted that it is possible to achieve both antistatic properties and functions other than water repellency. It has been found that when using a deep color agent, the antistatic performance may decrease.
[0008]
[Problems to be solved by the invention]
An object of the present invention is to solve the above-mentioned problems of the prior art and provide a polyester fiber fabric having improved antistatic durability and deep color and a method for producing the same.
[0009]
[Means for Solving the Problems]
As a result of intensive studies to achieve the above object, the present inventors have found that both layers of a reactive urethane polymer and a deep color polymer (hereinafter sometimes simply referred to as a color deepening agent) having antistatic properties on the polyester fiber fabric. It was determined that a desired fabric can be obtained when a part of the reactive urethane polymer layer is coated with a deep colorant layer.
[0010]
That is, according to the present invention, there is provided a fabric mainly composed of polyester fibers to which a reactive urethane polymer film having antistatic ability and no color deepening agent is fixed, the reactive urethane polymer film At least a portion is a polymer formed from a reactive compound containing a perfluoroalkyl group, and is coated with a deep coloring agent that does not contain an antistatic agent. Provided is a deep-colored polyester fiber fabric having improved antistatic durability, wherein the L * value is 0.5 or more and the frictional voltage after 10 washings is 1.5 KV or less.
[0011]
Further, according to the present invention, after a reactive urethane polymer film having antistatic ability, in which a deep colorant is not mixed, is fixed to a cloth mainly composed of polyester fibers, the reactive urethane polymer film is further added. The antistatic durability is improved by forming a film of a deep colorant that is a polymer formed from a reactive compound containing a perfluoroalkyl group and does not contain an antistatic agent. A method for producing a deep color polyester fiber fabric is provided.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The fabric mainly composed of polyester fibers used in the present invention includes woven and knitted fabrics using only polyester fibers, non-woven fabrics, mixed products of polyester fibers and nylon fibers, mixed products of polyester fibers and cotton, and polyester fibers. This refers to those containing 50% or more of polyester fiber, such as wool mixed goods, polyester fiber and rayon.
[0013]
The reactive urethane polymer used in the present invention has antistatic performance, and preferably has a water solubility of 20% or less after being immersed in 20 ° C. water for 24 hours.
[0014]
When the above-described polymer having a solubility in water of more than 20% is used, when the below-described soaping is performed, the amount of the polymer dropped off is too large, and the antistatic effect may not be achieved.
[0015]
Further, the deep colorant used in the present invention is preferably a reactive compound containing a perfluoroalkyl group, and specifically includes a reactive compound represented by the following general formula.
[0016]
[Chemical 3]
Figure 0003759240
[0017]
In the formula, R is hydrogen or a lower alkyl group, Rf is a group containing a perfluoroalkyl group represented by Cm F2m + 1, and at least one group selected from a hydroxyl group, an ester group, an amino group, and an unsaturated alkyl group. M represents an integer of 2 to 21 or an integer of 10 to 200.
[0018]
The polymer is a copolymer composed of two or more kinds of polymers, or a polymerizable compound other than the polymer and the polymer, for example, a vinyl compound such as acrylic acid, methacrylic acid, styrene, vinyl chloride, and the like. The copolymer may be used in the form of a copolymer of acryl, a vinyl acetate compound, a melanin compound or the like.
[0019]
For the purpose of enhancing the durability of the deep color performance, a polyfunctional aziridine compound represented by the following formula may be used in combination with the above polymer.
[0020]
[Formula 4]
Figure 0003759240
[0021]
(However, R represents hydrogen or a methyl group.)
[0022]
The fabric of the present invention is mainly composed of polyester fibers to which a reactive urethane polymer film having antistatic ability is fixed, and a part of the reactive urethane polymer film is coated with a deep colorant. is necessary.
[0023]
Here, the polyester fiber to which the reactive urethane polymer film is fixed is a single fiber that is impregnated with the compound capable of forming the reactive urethane polymer and then dried and cured to fix the polymer film. Or say yarn.
[0024]
That is, in the fabric of the present invention, the reactive urethane polymer layer fixed to the fiber and the deep color layer covering the reactive urethane polymer layer are present independently, Each agent can sufficiently exhibit its function.
[0025]
As a specific method for producing the fabric as described above, first, a polyester fiber fabric is impregnated with a compound capable of forming a reactive urethane polymer by a pad method, a coating method, a spray method, or the like. Ring to adhere the polymer coating to the fiber.
[0026]
At this time, it is necessary to use a reactive urethane polymer that does not contain a deep colorant. The drying condition is preferably 100 to 130 ° C. for 1 to 5 minutes, and the curing condition is 150 to 180 ° C. for 1 to 3 minutes.
[0027]
Next, a reactive urethane polymer can be obtained by impregnating and adhering a compound capable of forming a reactive compound containing a perfluoroalkyl group to the fabric by a pad method, a coating method, a spray method, or the like, followed by curing after drying. The film can be coated with a deep color agent.
[0028]
At this time, it is necessary to use a deep coloring agent that does not contain an antistatic agent. The drying conditions and curing conditions may be the same as those for the reactive urethane polymer.
[0029]
Furthermore, after the reactive urethane polymer film is fixed, it is preferable to perform soaping in hot water at 40 to 80 ° C. for 10 to 20 minutes prior to the impregnation and adhesion of the deep colorant.
[0030]
Since excessive reactive urethane polymer is removed by performing soaping, the above-mentioned independent layer is easily formed when coated with a deep colorant, and the effects of the present invention are remarkably exhibited.
[0031]
The polyester fiber fabric thus obtained has a good deep color property, and the antistatic durability is remarkably improved. Even after 10 washes, the difference in ΔL * value is The high deep color property of 0.5 or more and the good antistatic property that the frictional voltage is 1.5 KV or less are maintained.
[0032]
[Action]
In the case of a conventional fabric in which an antistatic agent and a deep colorant are mixed and adhered, the antistatic agent has a strong hydrophilic property, so that the function of the deep colorant is reduced and is easy to wash. Therefore, both agents offset each other, and neither the antistatic function nor the deep color function was fully exhibited, and only a fabric having poor durability was obtained.
[0033]
In contrast, the polyester fiber fabric of the present invention has two layers, a reactive urethane polymer film fixed to the fiber and a deep colorant layer that covers the reactive urethane polymer film. Therefore, each agent can sufficiently exhibit its function, and the reactive urethane polymer can be prevented from falling off by washing or the like, and the durability of the antistatic performance can be remarkably improved.
[0034]
Although the details of the reason are not clear, when the reactive urethane polymer film and the deep colorant layer are formed on the fabric by the above-described method, the reactive urethane weight is formed on the fiber surface when viewed microscopically. A part where only the coalesced film is fixed (the sea) and a part where the reactive urethane polymer film is further coated with a deep colorant layer (island) are formed in a sea-island shape, and the former mainly has an antistatic effect, In addition, the latter mainly exhibits the effect of preventing the reactive urethane polymer from dropping off, and the deep color when viewed macroscopically is presumed that the deep colorant layer in the island portion exhibits the effect.
[0035]
