上述の各々のモノマーを共重合する方法としては通常のビニル重合方法を適用するが、重合開始剤としてはベンゾイルパーオキサイドおよび その誘導体、アゾビスブチロニトリル、アゾビスバレロニトリルなどの有機系重合開始剤が好ましく、これらの重合開始剤 ならびに、前述のモノマーを重合釜に入れ窒素パージにより、酸素を除去した状態で加熱重合させる。   As a method for copolymerizing each of the above-mentioned monomers, a usual vinyl polymerization method is applied. As a polymerization initiator, organic polymerization such as benzoyl peroxide and its derivatives, azobisbutyronitrile, azobisvaleronitrile, etc. An agent is preferred, and these polymerization initiators and the above-mentioned monomers are placed in a polymerization vessel and subjected to heat polymerization in a state where oxygen is removed by nitrogen purge.

上述の各々のモノマーを共重合することにより、親水性・撥油剤を形成するが、その際の(A)、(B)、(C)のモノマー比は1.00:1.50〜5.00:2.00〜6.50が望ましく、特に1.00:3.00〜4.50:4.00〜5.00が本発明の目的とする汗などの液体を吸収し、一方 人体からの油脂などによる汚れ付着を防止する意味から好ましい。   By copolymerizing each of the above-mentioned monomers, a hydrophilic / oil repellent agent is formed. In this case, the monomer ratio of (A), (B), (C) is 1.00: 1.50-5. 00: 2.00-6.50 is desirable, and especially 1.00: 3.00-4.50: 4.00-5.00 absorbs liquids such as sweat intended by the present invention, while from the human body. It is preferable from the viewpoint of preventing the adhesion of dirt due to oil and fat.

(A):(B):(C)の配合割合において、(A)が多すぎると撥水・撥油性が良くなるが、吸水性が極端に低下する。また (A)の化合物が少なすぎると撥油性が著しく低下する。また (B)の化合物の使用量が多くなると吸水性は著しく向上するが、撥油性が極端に低下してしまう傾向があり、逆に(B)の化合物の使用量が少なすぎると撥油性は著しく向上するが、吸水性能が低下してしまう。一方 (C)の化合物が多くなりすぎると吸水・撥油性能共に低下してしまい、また 使用量が少なすぎると吸水・撥油性能の洗濯耐久性が低下する。
したがって、上述の配合割合が必須であることが理解できる。
In the blending ratio of (A) :( B) :( C), when (A) is too much, water and oil repellency is improved, but water absorption is extremely lowered. Moreover, when there are too few compounds of (A), oil repellency will fall remarkably. Further, when the amount of the compound (B) used is increased, the water absorption is remarkably improved, but the oil repellency tends to be extremely lowered. Conversely, when the amount of the compound (B) used is too small, the oil repellency is decreased. Although it improves remarkably, water absorption performance will fall. On the other hand, if the amount of the compound (C) is too large, both the water absorption and oil repellency are deteriorated, and if the amount is too small, the washing durability of the water absorption and oil repellency is deteriorated.
Therefore, it can be understood that the above-mentioned blending ratio is essential.

本発明において、前述の共重合体に次の樹脂・架橋剤類を併用すると、本発明の目的である親水性・撥油効果の洗濯耐久性が向上し、より実用性が高まる。具体的にはグリオキザール系樹脂、メラミン系樹脂、ブロックイソシアネート系架橋剤、エポキシ系架橋剤などであり、これらの内の少なくとも1種を併用することにより、布帛上で上述の共重合体の架橋が進み、布帛の親水・撥油性に関する洗濯耐久性能が著しく向上するものである。   In the present invention, when the following resin / crosslinking agent is used in combination with the above-mentioned copolymer, the washing durability of the hydrophilic / oil-repellent effect which is the object of the present invention is improved, and the practicality is further increased. Specifically, it is a glyoxal resin, a melamine resin, a blocked isocyanate crosslinking agent, an epoxy crosslinking agent, etc., and by using at least one of these in combination, the above-mentioned copolymer is crosslinked on the fabric. As a result, the washing durability performance regarding the hydrophilicity / oil repellency of the fabric is remarkably improved.

なお、イソシアネート系架橋剤としては、トリイソシアネート化合物、ジイソシアネート化合物がよく、それらのポリイソシアネート化合物でも良い。
具体的には、ヘキサメチレンジイソシアネート、トリメチルヘキサメチレンジイソシアネート、ヘキサメチレントリイソシアネート、リジンエステルトリイソシアネート、イソホロンジイソシアネート、水添キシリレンジイソシアネート、トルエンジイソシアネート、キシレンジイソシアネート、ジフェニルメタンジイソシアネートなどがあるが、特にヘキサメチレンジイソシアネートのトリスビュレット変性体などのヘキサメチレンジイソシアネートの変性物であるトリイソシアネート化合物が好ましい。
In addition, as an isocyanate type crosslinking agent, a triisocyanate compound and a diisocyanate compound are good, and those polyisocyanate compounds may be sufficient.
Specific examples include hexamethylene diisocyanate, trimethylhexamethylene diisocyanate, hexamethylene triisocyanate, lysine ester triisocyanate, isophorone diisocyanate, hydrogenated xylylene diisocyanate, toluene diisocyanate, xylene diisocyanate, and diphenylmethane diisocyanate. A triisocyanate compound which is a modified product of hexamethylene diisocyanate, such as a modified tris burette, is preferable.

また、本発明において、前述の共重合体に次のポリアルキレングリコール変性樹脂類を併用すると親水性が向上し、布帛の液体汗などの吸収を向上させる働きがある。具体的にはポリエチレングリコール変性ポリエステル系樹脂、ポリエチレングリコール変性シリコン樹脂、ポリエチレングリコール変性ウレタン樹脂、ポリエチレングリコール変性エポキシ樹脂などの少なくとも1種を併用すればよい。   In the present invention, when the following polyalkylene glycol-modified resins are used in combination with the above-mentioned copolymer, the hydrophilicity is improved, and the absorption of liquid sweat and the like of the fabric is improved. Specifically, at least one kind of polyethylene glycol-modified polyester resin, polyethylene glycol-modified silicon resin, polyethylene glycol-modified urethane resin, polyethylene glycol-modified epoxy resin and the like may be used in combination.

また、本発明において次に記載する親水化化合物を併用すると、これもまた本発明の目的である親水・撥油性能を向上させる働きが助長される。
具体的には、ポリビニルアルコール、カルボメチルセルロース、キシリトール、エリスリトール、ポリエチレングリコール、さらには プルロニック、ソルビタン、アミノ酸型界面活性剤の少なくとも1種を併用すれば良い。
In the present invention, when a hydrophilic compound described below is used in combination, the function of improving the hydrophilic / oil-repellent performance, which is also the object of the present invention, is promoted.
Specifically, at least one of polyvinyl alcohol, carbomethylcellulose, xylitol, erythritol, polyethylene glycol, pluronic, sorbitan, and amino acid type surfactant may be used in combination.

これらの樹脂・架橋剤類、ポリアルキレングリコール変性樹脂類、親水化化合物類は、前述の親水・撥油共重合体に対し、20%以下の配合割合で併用すれば、十分 親水・撥油機能の向上が図れる。20%以上の配合では逆に本発明の目的とする優れた吸水・撥油性能が低下してしまい、意味をなさなくする。   These resins / crosslinking agents, polyalkylene glycol-modified resins, and hydrophilizing compounds are sufficiently hydrophilic / oil repellent function when used in a blending ratio of 20% or less with respect to the aforementioned hydrophilic / oil repellent copolymer. Can be improved. On the other hand, if it is 20% or more, the excellent water absorption and oil repellency performance aimed at by the present invention is lowered, making it meaningless.

以上記述した親水・撥油加工剤ならびに添加物からなる加工液で繊維、布帛類を処理・加工するが、その際の処理・加工法としては通常の浸漬法、スプレー法、パッド・キュア法、パッド・スチーム法などいずれの方法でも良いが、パッド・キュア法が最も効果の発現が良好であり、好ましい加工方法と言える。   Fibers and fabrics are treated and processed with the processing fluid comprising the hydrophilic / oil repellent finishing agent and additives described above, and the treatment / processing methods at that time include the usual dipping method, spray method, pad cure method, Any method such as a pad / steam method may be used, but the pad / cure method is most preferable because it produces the most effective effect.

なお、繊維の形態としては、ステープルや糸の状態 あるいは 編み織物や不織布のような布帛状態いずれでも良いが、布帛状態での処理・加工がしやすく、効果も発現しやすい。   The form of the fiber may be any of a staple or yarn state or a fabric state such as a knitted woven fabric or a non-woven fabric. However, the treatment and processing in the fabric state are easy and the effect is easily exhibited.

以下、実施例および比較例をあげて、本発明をさらに説明するが、本発明はこれらに限定されるものではない。   Hereinafter, the present invention will be further described with reference to Examples and Comparative Examples, but the present invention is not limited thereto.

以上の結果より、本発明の親水・撥油加工剤(A)、(B)、(C)の配合比率が、本発明の限定範囲を外れると、良好な吸水性、撥油性、ならびに洗濯耐久性などが得られず、本発明の目的を達成することが難しい。したがって、本発明の限定範囲が必須であることが判る。   From the above results, when the blending ratio of the hydrophilic / oil repellent agent (A), (B), (C) of the present invention is outside the limited range of the present invention, good water absorption, oil repellency, and washing durability are obtained. It is difficult to achieve the object of the present invention. Therefore, it turns out that the limited range of this invention is essential.

本発明の親水・撥油加工剤 ならびに、該加工剤で加工を施した布帛でシャツなどの縫製品にしたものは、人体からの液状の汗を吸収し、一方 皮脂系のオイル ならびに、それと共に付着するオイル状の汚れを布帛に極力 付着させないので、シャツなどの襟が襟垢汚れにより、汚染されることが無く、快適性を付与すると共に衛生性(清潔感)も同時に付与できる。
The hydrophilic / oil-repellent finishing agent of the present invention and the fabric processed with the finishing agent into a sewn product such as a shirt absorbs liquid sweat from the human body, while sebum oil and Since the oily dirt adhering to the cloth is prevented from adhering to the cloth as much as possible, the collar of the shirt or the like is not contaminated by the dirt on the collar, and it provides comfort and hygiene (clean feeling) at the same time.
