【発明の属する技術分野】
本発明は衛生性に優れるポリエステルおよび変性ポリエステル系繊維製品の加工法、更に詳しくはポリエステルおよび変性ポリエステル系繊維組織内に殺菌剤を固定化して該繊維に衛生性を持たせる方法に関する。
【0002】
【従来の技術】
靴下、肌着、スポーツ衣料、寝具等は使用者の皮膚よりの分泌物、汗、皮膚の剥離物等が付着し、これらが栄養源となって細菌、ダニ等の微生物が繁殖する良好な培地となり、微生物の生産物によって不快感を発生し、場合によっては皮膚病等の感染原因ともなる。また、蒲団、敷物、カーテン、壁布地等は保管の際や湿度の高い場所で使用する場合等に黴が発生して繊維の劣化汚染等による品位の低下がおこる。
【0003】
繊維製品を細菌、ダニ等の微生物や黴から保護して衛生的に保ち、また品位を良好に維持する目的で繊維製品に殺菌剤を固着させる試みがなされ、今までに幾つかの方法が実施されている。最も一般的には殺菌剤を含む液に繊維製品を浸漬或いは噴霧する方法が、更に殺菌剤の固着を強力にする方法として、例えば、殺菌性第4級アンモニュウム塩の分子の一部を有機シリコン化合物を介して繊維分子の一部に結合する方法、或いは有機塩素化合物等の殺菌性化合物を展開性のよい合成樹脂で繊維表面に被覆接着して固定化する方法、或いは無機金属(銀系など)を繊維中に練込む方法、或いは繊維物質の組成中に有機金属化合物を結合させて抗菌性を持たせる方法などが知られている。
【0004】
しかしこれらの対象として用いられる繊維は専ら木綿、毛、絹、アセテート、アクリル系、ポリアミド系、塩化ビニール系、ポリウレタン系等である。
【0005】
これらの物質は原則として繊維構成分子中に第三物質分子と化学的または物理的に結合する性能を有する官能基を持ているか又は改質によりこのような官能基を導入したもの、或いは繊維表面の物性が合成樹脂接着剤との親和性に優れたものである。
【0006】
また、一般に繊維との親和性が高いカチオン活性剤系殺菌剤を付着させることも行われているが耐久性に問題がある上に、塵埃を吸着して汚れ現象が目立つ欠点があるとされている。
【0007】
【発明が解決しようとする課題】
ポリエステルおよび変性ポリエステル系繊維は、接着剤との親和性が悪いため接着剤併用による殺菌剤固定も不十分であり、繊維仕上げ行程の処理条件に耐え、繊維本来の風合をそこなわず、また十分な耐光性と耐洗濯性を備え、かつ長期間効力を持続し得るポリエステルおよび変性ポリエステル系繊維の衛生加工方法は知られていなかった。
【0008】
【課題を解決するための手段】
本発明者はポリエステルおよび変性ポリエステル系繊維製品に良好な衛生性を付与する方法につき、種種検討し、ポリエステルおよび変性ポリエステル系繊維を形成する鎖状高分子の集合体の間隙に殺菌剤を侵入させて固定化させることを試み、耐光、耐洗濯性に優れ、長期間殺菌高価を持続させる本発明の衛生加工法に到達した。すなわち本発明は、リン含有エステル形成性化合物を共重合した変性ポリエステル系繊維製品に殺菌剤または殺菌剤を含む昇華性染料を付与した転写紙を用いて170〜210℃下で転写捺染することで殺菌剤を繊維製品に固着することを特徴とする衛生性に優れるポリエステルおよび変性ポリエステル系繊維製品の加工法である。

本発明の衛生性に優れるとは、抗菌性、防臭性、防黴性など微生物から生活環境を衛生的に保つのに優れていることを意味する。
【0013】
本発明の方法に用いる殺菌剤としては親水性の強いもの、着色性のあるもの、臭気または刺激の強いもの、昇華性の強いもの、日光に照射されると変質するもの、毒性が強いもの、塩素を含むもの等を除いてほとんどのものが適用できるが、特に染色不良、退色促進、染料滲出、移染、黄変、異臭等による繊維製品の品位低下を起こさない好ましい殺菌性化合物の例としては、3−メチル−4−イソプロピルフェノール(3M4P)、チモール、p−オキシ安息香酸アルキルエステル(アルキルはメチル、エチル、n−およびiso−プロピル、n−およびsec−またはter−ブチル、ペンチル等)、 グルセリンモノ脂肪酸エステル(脂肪酸はカブリル酸、カブリン酸、ラウリン酸等)、2−(4−チアゾリル)−ベンズイミダゾール(TBZ)、2−メトキシカルボニルアミノベンズイミダゾール(MBC)、2−メトキシカルボニルアミノベンズイミダゾール、4′−n−ドデシルベンゼンスルホン酸塩(MBC-S)、10,10′−オキシビスフェノキシアルシン、8−オキシキノリン銅、キャプタン、ダイホルタン等が挙げられ、2種以上混合してもよく、特に、3M4Pがその加工性、耐久性、安全性等の特性が良く、抗菌剤として好ましい。
【0014】
本発明方法による繊維加工方法は被処理繊維製品に殺菌剤、または、殺菌剤を含む昇華性染料を付与した転写紙を用いて両面転写捺染して浸透固着させる方法である。この場合処理温度170〜210℃、処理時間20〜70秒から選ばれた条件で処理される。なお、本法では常圧で高温で処理されるので処理温度において蒸気圧が低い殺菌性化合物を選ぶ必要がある。
【0015】
また本発明に係る転写捺染は少なくとも片面、好ましくは両面の転写捺染であり、その両面転写捺染布帛の製造方法は、転写紙に付与された昇華性染料を布帛の両面に昇華転写する方法において、第1の転写紙を前期布帛の片面側に重ね合せ、且つ第2の転写紙を前記布帛の他面側に重ね合せて、少なくとも3層の積層構造とし、該積層構造の両面から圧し付けた状態で加熱して、前記第1、2の転写紙の夫々の昇華性染料を前記布帛の夫々の面に昇華移行させるものである。
【0016】
いずれの方法においても殺菌性化合物が繊維の重量に対して殺菌剤の殺菌効力に応じて0.001〜2.0%の範囲内の所定量以上が繊維内に取り込まれることが必要で、処理方法、使用殺菌剤に応じた有効率(殺菌剤を含む水溶液中の殺菌性化合物が繊維中に取り込まれる割合)を実験的に確認して実際に必要な殺菌剤量が決定される。
【0017】
本発明の方法はポリエステルおよび変性ポリエステル系繊維の鎖状高分子の集合体の間隙に適切な殺菌性化合物を侵入させて安定に固定化させたもので、効力は長期間安定に持続し優れた耐洗濯性を示す。本発明方法で処理されたポリエステルおよび変性ポリエステル系繊維製品は風合の劣化、撥水性や塵埃吸着性の付与その他変性ポリエステル系繊維の持つ特性(難燃性、カチオン可染性、高収縮性、分散常圧可染性等)を損なう性質が発現することはない。また、吸着された殺菌剤有効成分は究めて微量に抑制されており安全性が高い。
【0018】
また、汎用ポリエステル繊維に対し、変性ポリエステル系繊維は、鎖状高分子の集合体の間隙が多く存在し、そのために殺菌性化合物の固定化率が高く、殺菌性化合物の使用量を極力削減し、廃水中に含まれて排出される殺菌性化合物を最小限に止めることが出来る。

BACKGROUND OF THE INVENTION
The present invention relates to a method of processing polyester and modified polyester fiber products having excellent hygiene, and more particularly to a method of immobilizing a bactericidal agent in polyester and modified polyester fiber structures to give the fibers hygiene.
[0002]
[Prior art]
Socks, underwear, sports clothing, bedding, etc., adhere to the secretions from the user's skin, sweat, exfoliation of the skin, etc., and these serve as nutrients and become a good medium for the growth of microorganisms such as bacteria and mites. Discomfort may be caused by the microbial product, and in some cases may cause infections such as skin diseases. In addition, straw mats, rugs, curtains, wall fabrics, etc., when stored or used in places with high humidity, cause wrinkles and lower the quality due to fiber degradation contamination.
[0003]
Attempts have been made to attach a disinfectant to a textile product in order to keep the textile product hygienic by protecting it from microorganisms such as bacteria, mites, etc., and maintaining good quality, and several methods have been implemented so far. Has been. The most common method is to immerse or spray the textile product in a liquid containing a bactericidal agent. Further, as a method to further strengthen the bactericidal agent fixing, for example, a part of molecules of a bactericidal quaternary ammonium salt is converted into organic silicon. A method of binding to a part of the fiber molecule through a compound, a method of coating and fixing a bactericidal compound such as an organic chlorine compound on the fiber surface with a synthetic resin having a good developability, or an inorganic metal (such as silver) ) Is kneaded into the fiber, or a method of imparting antibacterial properties by combining an organometallic compound in the composition of the fiber material.
[0004]
However, the fibers used as these objects are exclusively cotton, wool, silk, acetate, acrylic, polyamide, vinyl chloride, polyurethane and the like.
[0005]
In principle, these substances have a functional group having the ability to chemically or physically bond with the third substance molecule in the fiber constituting molecule, or those functional group introduced by modification, or the surface of the fiber. The physical properties are excellent in affinity with the synthetic resin adhesive.
[0006]
In addition, a cationic activator-based disinfectant having a high affinity for fibers is generally attached, but there is a problem in durability, and there is a defect that the dirt phenomenon is noticeable by adsorbing dust. Yes.
[0007]
[Problems to be solved by the invention]
Polyester and modified polyester fibers have poor compatibility with adhesives, so the disinfectant is not sufficiently fixed with the adhesive, withstands the processing conditions of the fiber finishing process, and does not detract from the original texture of the fiber. There has been no known hygienic processing method for polyester and modified polyester fiber that has sufficient light resistance and washing resistance and can maintain its efficacy for a long period of time.
[0008]
[Means for Solving the Problems]
The present inventor has studied various methods for imparting good hygiene to polyester and modified polyester fiber products, and has a fungicide infiltrated into the gap between the aggregates of chain polymers forming the polyester and modified polyester fibers. The hygienic processing method of the present invention has been achieved, which is excellent in light resistance and washing resistance and maintains sterilization cost for a long period of time. That is, the present invention is a method of transfer printing at 170-210 ° C. using transfer paper in which a disinfectant or a sublimation dye containing a disinfectant is added to a modified polyester fiber product copolymerized with a phosphorus-containing ester-forming compound. This is a method for processing polyester and modified polyester fiber products excellent in hygiene, characterized by adhering a disinfectant to the fiber product.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The objects of the method of the present invention include all polyesters and modified polyester fiber products that can be transferred and printed, such as woven and knitted fabrics and nonwoven fabrics.
[0010]

Figure 0003972278
(In the formula, R 1 is a monovalent ester-forming functional group, R 2 and R 3 are the same or different groups, and each is a halogen atom, a hydrocarbon group having 1 to 10 carbon atoms, R 1 A represents a divalent or trivalent organic residue, and n 1 represents 1 or 2, n 2 and n 3 each represents an integer of 0 to 4).
Cationic dyeable polyester fibers copolymerized with cationic dyeable ester forming compounds, high shrinkage polyester copolymerized with isophthalic acid, atmospheric pressure dyeable polyester fibers kneaded or copolymerized with polyethylene glycol, and other modified polyester fibers Is included.
[0011]
[Chemical 2]
Figure 0003972278
[0012]
The superior hygiene of the present invention means that the living environment is excellently maintained hygienically from microorganisms such as antibacterial, deodorant and antifungal properties.
[0013]
As the bactericidal agent used in the method of the present invention, those having strong hydrophilicity, those having coloring properties, those having strong odor or irritation, those having strong sublimation properties, those that change in quality when exposed to sunlight, those that are highly toxic, Most of them can be applied except those containing chlorine, but especially as examples of preferred bactericidal compounds that do not cause deterioration of the quality of textile products due to poor dyeing, fading promotion, dye leaching, dye transfer, yellowing, nasty smell, etc. Is 3-methyl-4-isopropylphenol (3M4P), thymol, p-oxybenzoic acid alkyl ester (alkyl is methyl, ethyl, n- and iso-propyl, n- and sec- or ter-butyl, pentyl, etc.) Glycerol mono fatty acid ester (fatty acid is cabrylic acid, cabric acid, lauric acid, etc.), 2- (4-thiazolyl) -benzimidazole (TBZ), 2-methoxycarbonylamino Imidazole (MBC), 2-methoxycarbonylaminobenzimidazole, 4'-n-dodecylbenzenesulfonate (MBC-S), 10,10'-oxybisphenoxyarsine, 8-oxyquinoline copper, captan, difortan, etc. Two or more types may be mixed, and 3M4P is particularly preferable as an antibacterial agent because of its good processability, durability, safety and other properties.
[0014]
The fiber processing method according to the method of the present invention is a method for carrying out double-side transfer printing and penetrating and fixing using a transfer paper provided with a bactericidal agent or a sublimable dye containing a bactericidal agent on a treated fiber product. In this case, the treatment is performed under conditions selected from a treatment temperature of 170 to 210 ° C. and a treatment time of 20 to 70 seconds. In this method, since the treatment is performed at normal pressure and high temperature, it is necessary to select a bactericidal compound having a low vapor pressure at the treatment temperature.
[0015]
Further, the transfer printing according to the present invention is at least one-sided transfer printing, preferably double-sided transfer printing, and the method for producing the double-sided transfer printing fabric is a method of sublimating and transferring a sublimation dye applied to transfer paper onto both sides of the fabric. The first transfer paper was superposed on one side of the fabric and the second transfer paper was superposed on the other side of the fabric to form a laminated structure of at least three layers, and pressed from both sides of the laminated structure. In this state, the sublimation dyes of the first and second transfer papers are sublimated and transferred to the respective surfaces of the fabric.
[0016]
In any method, the bactericidal compound needs to be incorporated into the fiber in a predetermined amount within the range of 0.001 to 2.0% depending on the bactericidal efficacy of the bactericide with respect to the weight of the fiber. The amount of fungicide actually required is determined by experimentally confirming the effective rate according to the agent (ratio in which the fungicidal compound in the aqueous solution containing the fungicide is taken into the fiber).
[0017]
In the method of the present invention, an appropriate bactericidal compound is infiltrated into the gap between the aggregates of the chain polymer of polyester and modified polyester fiber and stably fixed, and the efficacy is stable and excellent for a long time. Shows wash resistance. Polyester and modified polyester fiber products treated by the method of the present invention have a feeling of deterioration, imparting water repellency and dust adsorbability and other properties of modified polyester fibers (flame retardant, cationic dyeability, high shrinkage, The properties which impair the dispersion normal pressure dyeability, etc.) are not exhibited. Further, the adsorbed active ingredient of the bactericide is controlled to a very small amount and is highly safe.
[0018]
In contrast to general-purpose polyester fibers, modified polyester fibers have many gaps between the aggregates of chain polymers, and therefore, the immobilization rate of the bactericidal compound is high, and the amount of the bactericidal compound used is reduced as much as possible. The bactericidal compounds contained and discharged in the wastewater can be minimized.
[0019]
