Description

本発明は、ポリエステル系制電剤、フッ素系撥水剤、およびポリイソシアネートを含む制電撥水加工剤、かかる制電撥水加工剤を付着させた洗濯耐久性のある制電撥水性布帛および繊維製品に関するものである。   The present invention relates to an antistatic water-repellent agent comprising a polyester-based antistatic agent, a fluorine-based water-repellent agent, and a polyisocyanate, a washing-resistant antistatic water-repellent fabric to which the antistatic water-repellent agent is attached, and It relates to textile products.

従来、スポーツ衣料やカジュアル衣料など撥水性を要求される分野において、ポリエステル繊維などで構成された布帛に撥水剤による処理が行われている。一方、ポリエステル繊維などで構成された布帛は、一般的に静電気を蓄積し易い性質をもち、衣類のまとわりつきなど着用者に不快感を与えることがある。このように、撥水性と制電性の両機能を同時に満足することが求められている。
しかしながら、この撥水性と制電性は相反する性質であり、例えば撥水性を付与すると、制電性が消失し、逆に制電性を付与すると撥水性が消失する。
Conventionally, in a field where water repellency is required, such as sports clothing and casual clothing, a fabric made of polyester fiber has been treated with a water repellent. On the other hand, a fabric made of polyester fiber or the like generally has a property of easily accumulating static electricity, and may cause discomfort to the wearer, such as clinging to clothing. Thus, it is required to satisfy both functions of water repellency and antistatic property at the same time.
However, the water repellency and the antistatic property are contradictory properties. For example, when the water repellency is imparted, the antistatic property is lost. Conversely, when the antistatic property is imparted, the water repellency is lost.

かかる撥水性と制電性を両立する方法として、例えば特許文献1では、合成繊維構造物表面にポリエーテルエステル樹脂層を形成させた後、制電防止剤を含むフッ素系撥水剤皮膜を形成させることが提案されているが、制電防止剤が単にフッ素系撥水剤皮膜中に混入されているだけあるため、十分な洗濯耐久性が得られないという問題があった。さらには、加工工程が二段階であるため、生産効率が悪いという問題もあった。   For example, in Patent Document 1, a polyether ester resin layer is formed on the surface of a synthetic fiber structure and then a fluorine-based water repellent film containing an antistatic agent is formed as a method for achieving both water repellency and antistatic properties. However, since the antistatic agent is merely mixed in the fluorine-based water repellent film, there is a problem that sufficient washing durability cannot be obtained. Furthermore, since the processing process is a two-stage process, there is a problem that the production efficiency is poor.

また、特許文献2では、ポリオキシエチレンのジアルキルアミンを含む帯電防止剤と、フッ素系撥水剤と、架橋剤としてブロックイソシアネートを含む水溶液を合成繊維製品に付与した後に加熱処理することが提案されている。かかる方法は、加工工程が一段階であるため生産効率はよいものの、やはり洗濯耐久性が十分でないという問題があった。   Patent Document 2 proposes that an antistatic agent containing a polyalkylethylene dialkylamine, a fluorine-based water repellent, and an aqueous solution containing a blocked isocyanate as a crosslinking agent be applied to a synthetic fiber product and then heat-treated. ing. This method has a problem that the washing durability is not sufficient although the production efficiency is good because the processing step is one stage.

An anti-repellent water-repellent polyester fabric and a textile product having a washing durability and having an adhesive attached thereto are provided.

以下、本発明の実施の形態について詳細に説明する。
まず、ポリエステル系制電剤Aは、ポリオキシエチレン(ポリエチレングリコール)を含む多価アルコールと芳香族多塩基酸とから合成されたものであり、制電剤に対しモル重量%が30〜95重量%(好ましくは50〜90重量%)のオキシエチレンセグメントと、制電剤に対しモル重量%が5〜20重量%(好ましくは8〜18重量%)の芳香族環とが主鎖中に含まれ、主鎖の少なくとも一方末端および/または側鎖に、水酸基および/またはカルボキシル基の官能基を2個以上(少なくとも水酸基とカルボキシル基とを1個ずつ、または、少なくともどちらかを2個)有する必要がある。
Hereinafter, embodiments of the present invention will be described in detail.
First, the polyester-based antistatic agent A is synthesized from a polyhydric alcohol containing polyoxyethylene (polyethylene glycol) and an aromatic polybasic acid, and a molar weight percent of the antistatic agent is 30 to 95 wt%. % (Preferably 50 to 90% by weight) of oxyethylene segments and an aromatic ring having a molar weight% of 5 to 20% by weight (preferably 8 to 18% by weight) based on the antistatic agent are contained in the main chain. And at least one terminal and / or side chain of the main chain has two or more functional groups of hydroxyl group and / or carboxyl group (at least one hydroxyl group and one carboxyl group, or at least two of them). There is a need.

前記オキシエチレンセグメントは制電性に寄与するセグメントであり、オキシエチレンセグメントの制電剤の重量に対する重量比が30重量%未満では、十分な制電性が得られず好ましくない。逆に該重量比が95重量%より大きいと、相対的に芳香族環の重量比が低下し好ましくない。   The oxyethylene segment is a segment that contributes to antistatic properties. If the weight ratio of the oxyethylene segment to the antistatic agent is less than 30% by weight, sufficient antistatic properties cannot be obtained, which is not preferable. Conversely, when the weight ratio is larger than 95% by weight, the weight ratio of the aromatic ring is relatively lowered, which is not preferable.

また、前記の芳香族環はポリエステル繊維との親和性に寄与するものであり、芳香族環の制電剤の重量に対する重量比が5重量%未満では、ポリエステル繊維との親和性が低下するため、制電性および撥水性の洗濯耐久性が低下し好ましくない。逆に、該重量比が20重量%よりも大きいと、相対的に前記オキシエチレンセグメントの重量比が低下し好ましくない。   The aromatic ring contributes to the affinity with the polyester fiber, and when the weight ratio of the aromatic ring to the antistatic agent is less than 5% by weight, the affinity with the polyester fiber is reduced. In addition, the antistatic and water-repellent washing durability is undesirably lowered. On the contrary, when the weight ratio is larger than 20% by weight, the weight ratio of the oxyethylene segment is relatively lowered, which is not preferable.

なお、前記オキシエチレンセグメント(CHCHO)の制電剤重量に対する重量比は下記式により算出することができる。ただし、44はCHCHOの分子量であり、下記式中のnはポリエステル系制電剤Aの化学構造式に含まれるオキシエチレンセグメント(CHCHO)の個数である。
(44×n/(ポリエステル系制電剤A全体の分子量))×100
The weight ratio antistatic agent by weight of the oxyethylene segment (CH 2 CH 2 O) can be calculated by the following equation. However, 44 is the molecular weight of CH 2 CH 2 O, and n in the following formula is the number of oxyethylene segments (CH 2 CH 2 O) contained in the chemical structural formula of the polyester antistatic agent A.
(44 × n / (molecular weight of polyester antistatic agent A as a whole)) × 100

同様に、芳香族環(−C−)の制電剤重量に対する重量比は下記式により算出することができる。ただし、76はCの分子量であり、下記式中のmはポリエステル系制電剤Aの化学構造式に含まれる芳香族環の個数である。
(76×m/(ポリエステル系制電剤A全体の分子量))×100
Similarly, the weight ratio of the aromatic ring (—C 6 H 4 —) to the weight of the antistatic agent can be calculated by the following formula. However, 76 is the molecular weight of C 6 H 4 , and m in the following formula is the number of aromatic rings contained in the chemical structural formula of the polyester antistatic agent A.
(76 × m / (molecular weight of polyester antistatic agent A as a whole)) × 100

前記の水酸基および/またはカルボキシル基の官能基は2個以上である必要があり、該個数が1個以下では、ポリエステル系制電剤AがポリイソシアネートCを介してフッ素系撥水剤Bと架橋される際、十分な架橋が得られず好ましくない。また、安定した架橋を得る上で、前記ポリエステル系制電剤Aにおいて、酸価および/または水酸基価の合計が1〜250の範囲内であることが好ましい。   The number of functional groups of the hydroxyl group and / or carboxyl group needs to be two or more. When the number is one or less, the polyester-based antistatic agent A crosslinks with the fluorine-based water repellent B via the polyisocyanate C. However, it is not preferable because sufficient crosslinking cannot be obtained. Further, in order to obtain stable crosslinking, it is preferable that the total of the acid value and / or the hydroxyl value is in the range of 1 to 250 in the polyester-based antistatic agent A.

前記のポリエステル系制電剤Aは、例えば、分子量が400〜1200程度のポリオキシエチレン単独か必要に応じてエチレングリコール、ジエチレングリコール、ブチレングリコールなどを含む多価アルコールと、テレフタル酸やイソフタル酸などの芳香族多塩基酸とを反応缶に仕込み、チタン系触媒を用いて減圧下、温度150〜200℃でエステル化することにより容易に得られる。その際、アジピン酸などの脂肪族多塩基酸が含まれていてもさしかえない。   The polyester-based antistatic agent A includes, for example, polyoxyethylene having a molecular weight of about 400 to 1200 alone or a polyhydric alcohol containing ethylene glycol, diethylene glycol, butylene glycol or the like as necessary, terephthalic acid, isophthalic acid, and the like. An aromatic polybasic acid is charged into a reaction can and esterified at a temperature of 150 to 200 ° C. under reduced pressure using a titanium catalyst. In that case, it does not matter if an aliphatic polybasic acid such as adipic acid is contained.

次に、フッ素系撥水剤Bは公知のものでよいが、N−メチロールアクリルアミド、(メタ)アクリル酸、ヒドロキシエチル(メタ)アクリレート等の官能基を有する重合性不飽和単量体を含むパーフロロアルキル(メタ)アクリレートを乳化重合してエマルジョン状態としたものが好適である。特に、メチロール基、アルコキシル基、アミノ基、カルボキシル基、および水酸基の群より選択されるいずれかの官能基が、フッ素系撥水剤Bの固形分に対して0.05〜10重量%含まれると、ポリイソシアネートCを介してポリエステル系制電剤Aと架橋される際、安定した架橋が得られ好ましい。具体的には、日華化学(株)製のNKガードNDN−9E(商品名)、旭硝子(株)製アサヒガードLS−317(商品名)、大日本インキ化学工業(株)デイックガードF−90Lなどがあげられる。   Next, the fluorine-based water repellent B may be a known one, but it contains a polymerizable unsaturated monomer having a functional group such as N-methylolacrylamide, (meth) acrylic acid, and hydroxyethyl (meth) acrylate. The emulsion-polymerized fluoroalkyl (meth) acrylate is preferably used. In particular, any functional group selected from the group of a methylol group, an alkoxyl group, an amino group, a carboxyl group, and a hydroxyl group is contained in an amount of 0.05 to 10% by weight based on the solid content of the fluorinated water repellent B. When the polyester-based antistatic agent A is crosslinked via the polyisocyanate C, stable crosslinking is preferably obtained. Specifically, NK Guard NDN-9E (trade name) manufactured by Nikka Chemical Co., Ltd., Asahi Guard LS-317 (trade name) manufactured by Asahi Glass Co., Ltd., Daikoku Ink Chemical Co., Ltd. Dick Guard F- 90L and so on.

またポリイソシアネートCとしては、一分子中にイソシアネート基および/またはブロックイソシアネート基を2個以上(少なくともイソシアネート基およびブロックイソシアネート基を1個ずつ、または、少なくともどちらかを2個)含有するものであれば特に限定されない。例えば、ヘキサメチレンジイソシアネート、トルエンジイソシアネートなどの油溶性タイプや、日本ポリウレタン(株)製アクアネートAQ−210(商品名)、大原パラデユウム(株)製パラキャットPGW(商品名)などがあげられる。   Further, the polyisocyanate C is one containing two or more isocyanate groups and / or blocked isocyanate groups in one molecule (at least one isocyanate group and one blocked isocyanate group, or at least one of them). If it does not specifically limit. Examples thereof include oil-soluble types such as hexamethylene diisocyanate and toluene diisocyanate, Aquanate AQ-210 (trade name) manufactured by Nippon Polyurethane Co., Ltd., and Paracat PGW (trade name) manufactured by Ohara Paradeum Co., Ltd.

本発明の制電撥水加工剤には、前記のポリエステル系制電剤A、フッ素系撥水剤B、およびポリイソシアネートCが含まれる。その際、これらの重量比としては、ポリエステル系制電剤A:フッ素系撥水剤B(固形分):およびポリイソシアネートCの比で、1:(2〜10):(0.2〜2.0)(より好ましくは、1:(4〜8):(0.5〜1.5))の範囲内であることが、洗濯耐久性に優れた制電撥水性が得られ好ましい。かかる重量比がこの範囲から外れる場合は、制電性および/または撥水性の洗濯耐久性が損なわれるおそれがある。   The antistatic and water repellent agent of the present invention includes the polyester antistatic agent A, the fluorinated water repellent B, and the polyisocyanate C. In this case, the weight ratio of these is the ratio of polyester-based antistatic agent A: fluorine-based water repellent B (solid content): and polyisocyanate C: 1: (2-10): (0.2-2) 0.0) (more preferably, 1: (4-8) :( 0.5-1.5)), it is preferable because antistatic water repellency with excellent washing durability is obtained. If the weight ratio is out of this range, the antistatic and / or water-repellent washing durability may be impaired.

次に本発明の制電撥水性ポリエステル布帛は、ポリエステル繊維で構成された布帛に、前記の制電撥水加工剤を付着させ、該制電撥水加工剤に含まれるポリエステル系制電剤Aとフッ素系撥水剤BとをポリイソシアネートCにより架橋させたものである。   Next, the antistatic and water repellent polyester fabric of the present invention is made by attaching the antistatic and water repellent agent to a fabric composed of polyester fibers, and the polyester antistatic agent A contained in the antistatic and water repellent agent. And fluorinated water repellent B are cross-linked with polyisocyanate C.

布帛を構成するポリエスエル繊維としては、テレフタル酸を主たるジカルボン酸成分とし、エチレングリコール、トリメチレングリコール、テトラメチレングリコールから選ばれた少なくとも1種のアルキレングリコールを主たるグリコール成分とするポリエステルからなるポリエステル繊維が好適である。該ポリエステルには、必要に応じて第3成分が共重合及び/又はブレンドされていてもよい。   The polyester fibers constituting the fabric include polyester fibers composed of a polyester having terephthalic acid as a main dicarboxylic acid component and at least one alkylene glycol selected from ethylene glycol, trimethylene glycol and tetramethylene glycol as a main glycol component. Is preferred. The polyester may be copolymerized and / or blended with a third component as necessary.

さらには、本発明の目的を損なわない範囲内で必要に応じて、艶消し剤、微細孔形成剤(例えば、有機スルホン酸金属塩など)、カチオン染料可染化剤(例えば、イソフタル酸スルホニウム塩など)、酸化防止剤(例えば、ヒンダーフェノール系酸化防止剤など)、熱安定剤、難燃剤(例えば、三酸化二アンチモンなど)、蛍光増白剤、着色剤、帯電防止剤(例えば、スルホン酸金属塩など)、吸湿剤(例えば、ポリオキシアルキレングリコールなど)などが添加剤として1種または2種以上、ポリエステル繊維中に含まれていてもよい。   Furthermore, a matting agent, a fine pore forming agent (for example, organic sulfonic acid metal salt), a cationic dye dyeing agent (for example, sulfonium salt of isophthalic acid) as necessary within the range not impairing the object of the present invention. Etc.), antioxidants (eg, hindered phenolic antioxidants), heat stabilizers, flame retardants (eg, antimony trioxide), fluorescent brighteners, colorants, antistatic agents (eg, sulfonic acid) 1 type, or 2 or more types may be contained in the polyester fiber as additives, such as a metal salt), a hygroscopic agent (for example, polyoxyalkylene glycol).

ポリエステル繊維の単糸繊維の形態は特に限定されず、長繊維(マルチフィラメント)であってもよいし、短繊維(ステープル)であってもよい。該単糸繊維の横断面形状は、その用途に応じて丸、三角、扁平、中空など適宜選定される。かかる繊維の単糸繊維としては特に限定されないが、繊維の表面積を大きくし制電撥水性を高める上で比較的細い繊度のほうが好ましく0.2〜3dtexの範囲内であることが好ましい。ポリエステル繊維糸条のフィラメント数としては20〜200本の範囲であることが好ましい。   The form of the single fiber of the polyester fiber is not particularly limited, and may be a long fiber (multifilament) or a short fiber (staple). The cross-sectional shape of the single yarn fiber is appropriately selected from round, triangular, flat, hollow and the like according to the application. Although it is not particularly limited as a single yarn fiber of such a fiber, a relatively fine fineness is preferable in the range of 0.2 to 3 dtex in order to increase the surface area of the fiber and increase the antistatic water repellency. The number of filaments of the polyester fiber yarn is preferably in the range of 20 to 200.

ポリエステル布帛の形態としては、特に限定はないが、目付け50〜200g/m程度の織物か編物であることが好ましい。さらには、かかるポリエステル布帛には、通常のアルカリ減量加工や染色仕上げ加工が施されていても何らさしつかえない。 The form of the polyester fabric is not particularly limited, but is preferably a woven fabric or a knitted fabric having a basis weight of about 50 to 200 g / m 2 . Furthermore, even if such a polyester fabric is subjected to normal alkali weight loss processing or dyeing finishing processing, there is no problem.

該制電撥水加工剤に含まれるポリエステル系制電剤Aとフッ素系撥水剤BとをポリイソシアネートCにより架橋させるには、例えば、前記の制電撥水加工剤に、必要に応じてアルキル錫化合物、アルキルチタン化合物等の有機金属化合物、アミン等慣用のイソシアネート用触媒を加えた後、水またはミネラルターペンなどの有機溶剤に希釈し、ポリエステル布帛に対し、純分換算で布帛重量対比0.5〜5.0重量%(より好ましくは1.0〜4.0重量%)付着させ、乾燥、熱処理するとよい。   In order to crosslink the polyester-type antistatic agent A and the fluorine-type water-repellent agent B contained in the antistatic water-repellent agent with the polyisocyanate C, for example, the antistatic water-repellent agent, if necessary, After adding a conventional isocyanate catalyst such as an organometallic compound such as an alkyltin compound or an alkyltitanium compound or an amine, it is diluted with water or an organic solvent such as mineral terpene, and the weight of the polyester fabric is 0 in comparison with the fabric weight. It is good to adhere 0.5 to 5.0 weight% (more preferably 1.0 to 4.0 weight%), and to dry and heat-process.

ここで、前記付着量が0.5重量%未満では、十分な制電撥水性が得られないおそれがある。逆に、前記付着量が5.0重量%より大きいと、風合いが硬くなったりコストアップとなるおそれがある。   Here, if the adhesion amount is less than 0.5% by weight, there is a possibility that sufficient antistatic water repellency cannot be obtained. On the other hand, if the adhesion amount is greater than 5.0% by weight, the texture may become hard or the cost may increase.
