【0001】
【発明の属する技術分野】
本発明はポリエステル繊維処理剤組成物に関する。詳しくはポリエステル繊維に平滑性、反発性、圧縮回復性、耐ヘタリ性などの特性を付与し得るポリエステル繊維処理剤組成物に関する。
【0002】
【従来の技術】
ポリエステル繊維は、ナイロン,アクリル,ポリ塩化ビニル,ポリプロピレンからなる繊維と比較して、圧縮弾性率が高く圧縮回復性に優れているため、布団綿,枕,クッション,縫いぐるみ等の詰め綿用ステープルファイバーに好適とされ、広く使用されている。従来、このポリエステル繊維を、アミノ基含有アルコキシシランやエポキシ基含有アルコキシシランなどのオルガノアルコキシシランを含む組成物で処理することにより、柔軟性、平滑性、並びに反発性、圧縮回復性などの特性を付与して羽毛や獣毛様の風合を付与する方法が知られている(特開昭49−133698号公報,特開昭50−48293号公報,特開昭58−214585号公報,特開昭62−41379号公報参照)。しかしこれらの方法においては、各種アルコキシシランから発生するアルコールが作業環境を汚染したり、火災を引き起こす恐れがある等の問題点があった。また、ポリエステル繊維をアミノ基含有ポリシロキサンとエポキシ基含有ポリシロキサンの混合物により処理する方法が提案されている(特公昭48−17514号公報,特開平5−59673号公報参照)。しかしこの方法では、目的とする効果を得るために高温での加熱処理が必要であり、ポリエステル繊維の劣化を引き起こすことがある等の問題点があった。
【0003】
【発明が解決しようとする課題】
本発明者らは、上記問題点を解消するために鋭意検討した結果、本発明に到達した。
すなわち、本発明の目的は、ポリエステル繊維、特には、ポリエステル繊維製詰め綿に対して、極めて優れた風合いを付与し得るポリエステル繊維処理剤組成物を提供することにある。
【0004】
【課題を解決するための手段】
本発明は、(A)一般式:
【化7】
(式中、Rは炭素原子数1〜20の置換もしくは非置換の一価炭化水素基であり、R1は炭素原子数1〜10の二価炭化水素基であり、R2およびR3は水素原子または炭素原子数1〜20の置換もしくは非置換の一価炭化水素基であり、Aは炭素原子数1〜20のアルキル基である。mおよびnは1以上の整数であり、aは0〜5の整数である。)で示されるアミノ基含有オルガノポリシロキサン、
(B)一般式:
【化8】
(式中、Rは炭素原子数1〜20の置換もしくは非置換の一価炭化水素基であり、R1は炭素原子数1〜10の二価炭化水素基であり、R2およびR3は水素原子または炭素原子数1〜20の置換もしくは非置換の一価炭化水素基である。xおよびyは1以上の整数であり、aは0〜5の整数である。)で示されるアミノ基含有オルガノポリシロキサン、
(A)成分と(B)成分の比率は重量比で(1:0.1)〜(1:10)
(C)非イオン界面活性剤
および
(D)水
からなる水性エマルジョンであることを特徴とするポリエステル繊維処理剤組成物に関する。
【0005】
【発明の実施の形態】
本発明組成物に使用される(A)成分のアミノ基含有オルガノポリシロキサンは、ポリエステル繊維に耐久性や反発性を付与するために必須とされる成分である。即ち、本成分のオルガノポリシロキサンが両末端のアルコキシ基の縮合反応によって高分子量化し、その結果、ポリエステル繊維に絡み付いて耐久性や反発性を向上させる。この(A)成分は、一般式:
【化9】
で示される。上式中、Rは炭素原子数1〜20の置換もしくは非置換の一価炭化水素基であり、具体例としては、メチル基,エチル基,プロピル基,ブチル基,オクチル基,デシル基,ドデシル基,テトラデシル基等の飽和脂肪族炭化水素基;ビニル基,アリル基等の不飽和脂肪族炭化水素基;シクロペンチル基,シクロヘキシル基等の飽和脂環式炭化水素基;フェニル基,トリル基,ナフチル基等の芳香族炭化水素基;およびこれらの基の水素原子が部分的にハロゲン原子またはエポキシ基等を含有する有機基で置換された基を挙げることができる。このRは同一であっても異なっていても良いが、メチル基が最も一般的である。R1は炭素原子数1〜10の二価炭化水素基であり、具体例としては、エチレン基,プロピレン基,ブチレン基等のアルキレン基;フェニレン基等のアリーレン基が挙げられるが、これらの中でもエチレン基またはプロピレン基が最も一般的である。R2およびR3は水素原子または炭素原子数1〜20の置換もしくは非置換の一価炭化水素基であり、一価炭化水素基の具体例としては前記Rと同様の基を挙げることができる。このR2およびR3は同一であっても異なっていても良い。Aは炭素原子数1〜20のアルキル基であり、メチル基,エチル基,プロピル基,ブチル基,オクチル基,デシル基,ドデシル基,テトラデシル基が例示される。mおよびnは1以上の整数であり、その上限は特に制限されないが、柔軟性、平滑性、圧縮回復性を付与するためには、上記オルガノポリシロキサンの25℃における動粘度が50mm2/s以上になる値であることが好ましく、動粘度が300〜30,000mm2/sの範囲となる値がより好ましい。aは0〜5の整数であるが、0または1が一般的である。また、上記一般式において、シロキサン単位の結合状態はブロック結合、ランダム結合のどちらでもよい。このような(A)成分のアミノ基含有オルガノポリシロキサンの代表的な製造方法としては、一般式:
【化10】
(式中、Rは前記どおりであり、pは1以上の整数である。)で示されるジオルガノシランもしくはジオルガノポリシロキサンと、一般式:
【化11】
(式中、R,R1,R2,R3,Aおよびaは前記どおりである。)で示されるオルガノアルコキシシランとを反応させる方法が挙げられる。ここで使用されるジオルガノポリシロキサンの具体例としては、25℃における動粘度が10〜30,000mm2/sであり、両末端が水酸基により封鎖されたジメチルポリシロキサンが挙げられる。オルガノアルコキシシランの具体例としては、N−β−(アミノエチル)−γ−アミノプロピルメチルジメトキシシランが挙げられる。反応方法の具体例としては、上記ジオルガノポリシロキサンとオルガノアルコキシシランを加熱下で反応させる方法や、または、これらを塩基性触媒を用いて加熱下で反応させた後、酸を用いて塩基性触媒を中和する方法が挙げられる。塩基性触媒の具体例としては、水酸化カリウム,水酸化ナトリウム,水酸化リチウムが挙げられる。
【0006】
このような(A)成分のアミノ基含有オルガノポリシロキサンとしては、下記式で示される化合物が例示される。
