Description
【０００１】
【発明の属する技術分野】
本発明は衛生性に優れる合成繊維製品の加工法、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】

BACKGROUND OF THE INVENTION
The present invention relates to a method for processing a synthetic fiber product excellent in hygiene, and more particularly, to a method for immobilizing a bactericidal agent in a polyester and modified polyester fiber structure to give the fiber 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]
Synthetic fibers such as polyester have poor affinity with adhesives, so the disinfectant fixation by adhesives is insufficient, withstands the processing conditions of the fiber finishing process, does not detract from the original texture of the fiber, In addition, there has been no known hygienic processing method for synthetic fibers that has sufficient light resistance and washing resistance and can maintain 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 synthetic fiber products, and tried to inject and fix a fungicide into the gap between the aggregates of chain polymers forming the synthetic fiber, It has reached the sanitary processing method of the present invention that is excellent in light resistance and washing resistance and maintains sterilization cost for a long time. That is, the present invention is a method for processing a synthetic fiber product excellent in hygiene, characterized in that the bactericide is fixed to the fiber product by transfer printing after applying a water-diluted solution of the bactericide to the synthetic fiber product.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The object of the method of the present invention includes all synthetic fiber products that can be transferred and printed, such as woven and knitted fabrics and nonwoven fabrics.
Synthetic fibers constituting the fiber product of the present invention are synthetic fibers such as polyester, polyamide, acrylic, and acetate. Among these, polyester and modified polyester are preferable because the effects of the present invention are remarkably exhibited.
[0010]

[0011]
[Chemical 1]
[0012]
[Chemical 2]
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.
[0014]
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.
[0015]
The fiber processing method according to the present invention is a method in which a bactericidal agent is applied to a fiber product to be treated by a putting method, a coating method, a dipping method, etc., and then single-sided or double-sided transfer printing is performed and the bactericidal agent is permeated and fixed by heating of transfer printing. is there. 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.
[0016]
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.
[0017]
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).
[0018]
The method of the present invention is a method in which an appropriate bactericidal compound is infiltrated into a gap between a chain polymer aggregate of synthetic fiber polymers such as polyester and modified polyester fiber, and the effect is stable for a long time. It is stable and has excellent washing 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.
[0019]
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.
