【式１】

本発明において、使用できる部分ケン化ポリビニルアルコールは、重合度が１５００〜５０００の範囲で、より好ましくは重合度が２０００〜３０００の範囲である。さらにケン化度が６０％〜８０％未満のものであり、より好ましくはケン化度が７０％〜８０％未満の範囲のものである。重合度が１５００未満のものは、乳化力が不足し、疎水性物質の安定した乳化物が得にくい。また重合度が５０００を超えるものは水に溶けにくくなり、また水溶液の粘度も上昇し乳化分散性に問題となる。ケン化度が６０％未満のものでは曇点が低くなり、低温で付着するため、むらづきになりやすい。反対にケン化度が８０％以上となると曇点が上昇し、繊維に付着しなくなる。
【００１４】
また乳化分散を行なうにあたって、繊維製品加工処理剤の安定化のため一般的な乳化剤も併用できる。アニオン系乳化剤としては、脂肪酸石鹸、アルキルサルフェートの金属塩、アルキルベンゼンスルホン酸ソーダ、アルキル硫酸塩などがある。カチオン系乳化剤としては、アルキルアミン塩、アルキルトリメチルアンモニウム塩、アルキルジメチルベンジルアンモニウム塩などがある。ノニオン系乳化剤としては、ポリオキシエチレンアルキルエーテル型、ポリオキシエチレンアルキルエステル型、ソルビタンアルキルエステル型、ポリオキシエチレンソルビタンアルキルエステル型などを用いてもよい。
【００１５】
本発明の繊維製品製造方法において、風合い調整や疎水性物質の付着耐久性向上の目的でバインダー樹脂液を繊維製品加工用処理剤と同時に用いることができる。樹脂としては水分散乳化系のアクリル酸エステル系樹脂、ポリウレタン系樹脂、シリコーン系樹脂、メラミン系樹脂、ポリエステル系樹脂、ポリアミド系樹脂、酢酸ビニール系などから適宜選べば良い。また樹脂の重合度は特に限定しないが、低分子量の樹脂を用い、ある一定温度になったら溶液中で重合が開始し高分子量となり繊維に付着するものが良い。この時に架橋剤を用いても良い。かかる樹脂付着繊維を取り出し、乾燥後、好ましくは１２０〜１８０℃の温度でキュアするのがよい。
【００１６】
本発明の繊維製品加工用処理剤の適用繊維製品の素材としては、木綿、絹、麻、羊毛、などの天然繊維あるいはナイロン、ポリエステル、ポリアクリロニトリル、ポリプロピレン、レーヨン、ベンベルグ、アセテートなどの合成繊維、半合成繊維、再生繊維あるいはこれらの混用繊維からなるものがあげられる。
【００１７】
かかる繊維からなる布帛としては、該繊維単独からなる編織物や不織布、あるいは混紡、混繊や交編織などの混用繊維布帛など各種適用されるが、いかなる構造、形状の布帛であってもさしつかえない。また糸状のものでもよい。
【００１８】
本発明の繊維製品加工用処理剤および繊維製品製造方法について例示すれば、本発明の部分ケン化ポリビニルアルコールの１０％以下の水溶液を事前に作成しておき、疎水性物質、適量の乳化剤、それに事前に作成した部分ケン化ポリビニルアルコールの水溶液、それに必要な水の約１／１０の水をホモジナイザーを用いて混合し、温度を約５０℃に保ちながら５０００ｒｐｍ以上で３０分乳化する。その後必要な水の残り約９／１０を加えて希釈し、撹拌しながら冷却すると本発明の繊維製品加工用処理剤が得られる。
【００１９】
次に本発明の繊維製品製造方法は、繊維製品布帛物１００に対して処理剤約１〜２０部（重量比）を事前に秤量しておく、液流染色機や撹拌付きバスなどを用いて浴比１：５〜１００になる様に水を張り、その中に繊維製品布帛物を投入し撹拌しながら事前に秤量しておいた処理剤を投入する、その後徐々に昇温していくとある温度（曇点）になったら液の乳化剤の白い色が消えて透明になってくる、その温度より若干高めの温度をキープしながら約５〜３０分間処理を行ない、その後除冷し繊維製品布帛物を取り出し乾燥する。この時に風合い調整や疎水性物質の付着耐久性向上の目的でバインダー樹脂液を本発明の処理剤と同時に用いることもできる。
【００２０】
処理温度は曇点またはそれ以上の温度が必要で、処理温度が５０℃以下であれば繊維に急激に付着して斑付きとなり好ましくない。１４０℃以上は染色堅牢度などの物性面や設備上の制約から好ましくない。より好ましい温度範囲は６０〜１００℃である。

BACKGROUND OF THE INVENTION
The present invention relates to a textile processing agent capable of imparting a moisturizing property, antibacterial property, deodorizing property, etc. that keeps a unique texture and fragrance or moist skin to a textile product, and a textile product comprising the same. It relates to a manufacturing method.
[0002]
[Prior art]
Conventionally, as a processing agent for imparting a hydrophobic substance to a textile product, means such as a method of dissolving a hydrophobic substance in an organic solvent or dispersing and emulsifying in water using an emulsifier has been adopted. In the case of the method of dissolving in such an organic solvent, since it is harmful to the human body, it is necessary to be careful in handling. Ventilation equipment is required in production facilities, and the organic solvent is used for dyeing fastness of textile products. There is a problem that the tendency to decrease is strong, and the fact is that it is not adopted so much in practice. Next, as a method of applying to the textile product, it is performed by a normal method such as a pad method, a spray method, a gravure coating method, etc., and at this time, it is room temperature, but since it is then dried in a dryer, Compared to before the hydrophobic substance was applied, the texture was considerably rough and hard. When observing with a microscope, the hydrophobic substance is partially solidified, especially at the entanglement points of the fibers, and the fibers are constrained in bundles, which hardened the texture It is. Further, such an adhesion form has a problem in durability because it easily drops off due to physical action.
[0003]
[Problems to be solved by the invention]
In view of the problems in the prior art, the present invention provides moisture retention, antibacterial properties, deodorization properties, etc. that maintain a unique texture and scent, or moist skin while maintaining a level of excellent durability. It is intended to provide a processing agent for processing textile products and a method for producing a textile product using the same.
[0004]
[Means for Solving the Problems]
The present invention employs the following means in order to solve such problems. That is, the textile processing agent of the present invention is characterized in that a hydrophobic substance and a partially saponified polyvinyl alcohol having a polymerization degree of 1500 to 5000 and a saponification degree of less than 60 to 80% are emulsified. To do.
[0005]
Moreover, the manufacturing method of the textiles of this invention is characterized by immersing textiles in the aqueous solution of the processing agent for textiles processing, and processing at the temperature more than the cloud point of this aqueous solution.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention has been intensively studied on processing agents for processing textile products that can impart moisturizing, antibacterial, and deodorant properties that maintain a unique texture, fragrance, or moist skin. The present inventors have unexpectedly found that the above-described problems can be solved at once when a composition comprising such partially saponified polyvinyl alcohol is used as a treating agent.
[0007]
In this case, that is, when a textile product is produced using such a treatment agent, the treatment is performed utilizing the cloud point of the treatment agent, that is, while maintaining the temperature condition above the cloud point. It has been found that a hydrophobic substance can be uniformly attached to the fiber, and that this has an extremely excellent effect in solving the above-mentioned problems.
[0008]
Here, the cloud point is the temperature at which the entire solution suddenly becomes cloudy when an aqueous solution of a surfactant is gradually heated, and the surfactant is deposited as fine droplets. It is. At this time, the deposited surfactant and hydrophobic substance adhere to the fiber product evenly (also referred to as adsorption).
[0009]
In the present invention, as the hydrophobic substance, cosmetic raw material ester oil, animal and plant oil-based materials, mineral oil-based materials, higher alcohol-based materials, solid fine powders, and the like can be used. Specifically, as the cosmetic raw material ester oil, isopropyl myristate, octyl myristate, octadecyl myristate, cetyl 2-ethylhexanoate, or the like can be used. As animal and vegetable oil-based materials, lanolin, squalane, horse oil, mink oil, coconut oil, olive oil, castor oil, orange luffy oil, jojoba oil, macadamian nut oil, perilla oil and the like can be used. As the mineral oily material, liquid paraffin, solid paraffin, isoparaffin, petrolatum and the like can be used. As the higher alcohol material, myristyl alcohol, cetanol, stearyl alcohol, vanol alcohol, behenyl alcohol and the like can be used. As the solid fine powder, a metal compound, an inorganic substance, or the like can be used.
[0010]
Some of these drugs are also used in cosmetics and have effects such as moisturizing, rough skin prevention, antibacterial properties, sun protection, etc. Since there is what it has, it can be used as necessary.
[0011]
The above partially saponified polyvinyl alcohol is a compound represented by the following general formula [1], and the degree of polymerization and the degree of saponification are determined by the following formulas.
[0012]
[Chemical 1]

Where [0013]
[Formula 1]

In the present invention, the partially saponified polyvinyl alcohol that can be used has a degree of polymerization in the range of 1500 to 5000, and more preferably in a range of 2000 to 3000. Further, the saponification degree is 60% to less than 80% , more preferably the saponification degree is in the range of 70% to less than 80%. When the degree of polymerization is less than 1500, the emulsifying power is insufficient and it is difficult to obtain a stable emulsion of a hydrophobic substance. Further, those having a degree of polymerization exceeding 5000 are difficult to dissolve in water, and the viscosity of the aqueous solution is increased, resulting in a problem with emulsifying dispersibility. When the degree of saponification is less than 60%, the cloud point becomes low and the film adheres at a low temperature, so that it tends to become uneven. On the other hand, when the degree of saponification is 80% or more , the cloud point rises and it does not adhere to the fiber.
[0014]
Further, when emulsifying and dispersing, a general emulsifier can be used in combination for stabilizing the fiber product processing agent. Examples of anionic emulsifiers include fatty acid soaps, metal salts of alkyl sulfates, sodium alkylbenzene sulfonate, and alkyl sulfates. Examples of the cationic emulsifier include alkylamine salts, alkyltrimethylammonium salts, and alkyldimethylbenzylammonium salts. As the nonionic emulsifier, polyoxyethylene alkyl ether type, polyoxyethylene alkyl ester type, sorbitan alkyl ester type, polyoxyethylene sorbitan alkyl ester type and the like may be used.
[0015]
In the textile product manufacturing method of the present invention, the binder resin liquid can be used simultaneously with the treating agent for textile product processing for the purpose of adjusting the texture and improving the adhesion durability of the hydrophobic substance. The resin may be appropriately selected from water-dispersed and emulsified acrylic ester resins, polyurethane resins, silicone resins, melamine resins, polyester resins, polyamide resins, vinyl acetate resins, and the like. The degree of polymerization of the resin is not particularly limited, but it is preferable to use a low molecular weight resin, and when a certain temperature is reached, the polymerization starts in the solution and becomes a high molecular weight and adheres to the fiber. At this time, a crosslinking agent may be used. Such resin-attached fibers are taken out and dried, and are preferably cured at a temperature of 120 to 180 ° C.
[0016]
As the material of the textile product to which the processing agent for textile product processing of the present invention is applied, natural fibers such as cotton, silk, hemp, wool, or synthetic fibers such as nylon, polyester, polyacrylonitrile, polypropylene, rayon, Bemberg, acetate, Examples thereof include semi-synthetic fibers, recycled fibers, and mixed fibers thereof.
[0017]
Various fabrics such as knitted fabrics and non-woven fabrics composed of the fibers alone, or mixed fiber fabrics such as mixed spinning, blended fibers, and interwoven fabrics may be used as fabrics composed of such fibers, but any structure and shape may be used. . Moreover, a thread-like thing may be sufficient.
[0018]
For example, the fiber product processing agent and the fiber product production method of the present invention are prepared in advance with an aqueous solution of 10% or less of the partially saponified polyvinyl alcohol of the present invention, a hydrophobic substance, an appropriate amount of emulsifier, An aqueous solution of partially saponified polyvinyl alcohol prepared in advance and about 1/10 of the necessary water are mixed using a homogenizer and emulsified at 5000 rpm or higher for 30 minutes while maintaining the temperature at about 50 ° C. Thereafter, about 9/10 of the remaining necessary water is added for dilution, and the mixture is cooled with stirring to obtain the treating agent for processing textile products of the present invention.
[0019]
Next, in the textile product manufacturing method of the present invention, about 1 to 20 parts (weight ratio) of the treatment agent is weighed in advance with respect to the textile product 100, using a liquid dyeing machine, a bath with stirring, or the like. Water is added so that the bath ratio becomes 1: 5 to 100, and the fabric product is put therein, and the treatment agent weighed in advance is added while stirring, and then the temperature is gradually raised. When a certain temperature (cloud point) is reached, the white color of the emulsifier in the liquid disappears and becomes transparent. It is treated for about 5 to 30 minutes while keeping the temperature slightly higher than that temperature, and then cooled to remove the fiber product. The fabric is removed and dried. At this time, the binder resin liquid can be used simultaneously with the treatment agent of the present invention for the purpose of adjusting the texture and improving the durability of adhesion of the hydrophobic substance.
[0020]
The treatment temperature needs to be a cloud point or higher, and if the treatment temperature is 50 ° C. or less, it is not preferable because it abruptly adheres to the fiber and becomes mottled. A temperature of 140 ° C. or higher is not preferable due to physical properties such as dyeing fastness and restrictions on equipment. A more preferable temperature range is 60 to 100 ° C.
[0021]

When the adhesion state was observed with a microscope, the fiber 1 was the same as in Example 1. It was in the state adhered uniformly to one book. As a result of measuring the durability of 20 washings due to weight change, the retention rate was 80%. The night glove obtained by the method of the present invention and the night glove before treatment were divided into left and right hands, and 10 female panelists were subjected to a comparative wearing test at bedtime for two months from January to February. When the stratum corneum moisture content was measured every two weeks for 2 months, the hands on the night gloves before treatment averaged 4%, and rough skin was observed. On the other hand, the hands on the night glove side obtained by the method of the present invention averaged 8%, and rough skin was not observed. There was also a significant difference in the feeling of wearing that the night gloves obtained by the method of the present invention were tight.

Comparative Example 1
200 g of a 5% aqueous solution of partially saponified polyvinyl alcohol (L-25 manufactured by Shin-Etsu Chemical Co., Ltd .; polymerization degree 2500, saponification degree 75%) was produced by the method for producing the textile product processing agent of the present invention used in Example 1. With the excluded formulation, a treatment agent was prepared as follows. Lanolin (500 g), sorbitan trioleate (40 g), polyoxyethylene nonylphenyl ether (ethylene oxide addition mole number: 10 mol) and water (100 g) were weighed. Next, polyoxyethylene nonylphenyl ether and water are put into a beaker equipped with a bath and heated with stirring at 7000 rpm using a homogenizer. When the temperature reaches 50 ° C., lanolin dissolved at 50 ° C. in advance The sorbitan trioleate mixture was added to the beaker. Thereafter, the mixture was stirred while keeping 50 ° C. for 30 minutes, and then the heating was stopped. Next, 1000 g of water at about 40 ° C. was added for dilution, and the stirring speed was lowered to 1000 rpm for cooling. The obtained product was emulsified white and uniform.
[0031]
Using 40 g of the dyed fabric dyed in woolen blue used in Example 1, the same mini-color dyeing machine as in Example 1 was used and the treatment was performed under the same conditions. The obtained product had almost no adhesion at 0.2% due to weight change. The touch and hardness were almost the same as before processing and no effect was obtained.
[0032]
The treatment agent obtained in Comparative Example 1 was diluted with 10 times the water, the fabric was immersed in the diluent at room temperature, squeezed with mangles, and then dried.
[0033]
The obtained product was the same as in Example 1 with an adhesion amount of about 1% due to weight change. The touch is a good quality with a slimy feeling that is very similar to wool, but the hardness becomes hard and there is a problem level. When the adhesion state is observed with a microscope, it is not in a state where the fibers are uniformly adhered to each fiber as in Example 1, but in a state in which the fibers are confined in a bundle shape with many at the entanglement points of the fibers. there were. As a result of measuring durability of 20 washings due to weight change, the retention rate was 20% which was considerably worse than Example 1.
