Description
本発明は繊維製品の処理方法に関する。 The present invention relates to a method for treating textile products.
近年、衣類に防臭効果を付与できる抗菌剤入り衣料用洗剤が関心を集めている。
従来の抗菌剤入り衣料用洗剤は衣類の洗濯時に用いられるもので、抗菌剤入り衣料用洗剤を多量の水で希釈した洗浄液で衣類を洗濯することによって防臭効果を付与する。
充分な防臭効果を付与するためには、希釈前の抗菌剤入り衣料用洗剤における抗菌剤の濃度を高くする必要があり、例えば抗菌剤であるダイクロサンは0.1質量%より多く配合されている(例えば、特許文献1)。
In recent years, laundry detergents containing antibacterial agents that can impart a deodorizing effect to clothing have been attracting attention.
Conventional laundry detergents containing antibacterial agents are used when washing clothes, and impart a deodorizing effect by washing the clothes with a cleaning solution in which the laundry detergent containing antibacterial agents is diluted with a large amount of water.
In order to provide a sufficient deodorizing effect, it is necessary to increase the concentration of the antibacterial agent in the antibacterial laundry detergent before dilution; for example, the antibacterial agent diclosan is blended in a concentration of more than 0.1 mass % (for example, Patent Document 1).
抗菌剤は比較的高価であるため、少ない使用量で充分な防臭効果を付与できることが望まれる。
本発明は、抗菌剤による防臭効果を効率良く付与できる、繊維製品の処理方法を提供することを目的とする。
Since antibacterial agents are relatively expensive, it is desirable to be able to impart sufficient deodorizing effect with a small amount of use.
An object of the present invention is to provide a method for treating textile products, which can efficiently impart a deodorizing effect by an antibacterial agent.

処理液(X)を繊維製品に塗布する方法は特に制限されない。例えば、処理液(X)を繊維製品にふりかけてもよく、直塗りしてもよい。
(Coating process)
When applying the treatment liquid (X) to a textile product, it is preferable to bring the treatment liquid (X) into contact with the textile product while maintaining the concentration of the treatment liquid (X). For this reason, it is preferable to apply the treatment liquid (X) to the textile product without immersing the textile product in water.
The amount of treatment liquid (X) applied is preferably 50% owf (amount of liquid detergent (X) applied per unit weight of textile product) or more by weight of fiber, more preferably 80% owf or more, and even more preferably 100% owf or more. There is no particular upper limit to the amount applied, but an amount that is, for example, 1000% owf or less by weight of fiber is preferred. If it is less than the lower limit, unevenness may occur and deodorizing performance may be difficult to exhibit.
The method of applying the treatment liquid (X) to the textile product is not particularly limited. For example, the treatment liquid (X) may be sprinkled or directly applied to the textile product.
塗布工程において、繊維製品(被処理物)に処理液(X)を塗布するとともに、(A)成分を含まない処理液(Y)をさらに塗布してもよい。
処理液(Y)は、処理液(X)中の(A)成分の繊維製品への吸着を妨げないものであればよく、特に限定されない。

(Leaving step)
After the treatment liquid (X) is applied to the textile product, the applied treatment liquid (X) is left to stand without being brought into contact with water. During the standing, the water in the treatment liquid (X) evaporates and the treatment liquid (X) is concentrated, so that the concentration of the component (A) becomes higher than the initial concentration.
During the time that the treatment liquid (X) is left standing, the area to which the treatment liquid (X) has been applied may be subjected to an external force, such as by rubbing or scrubbing, without contacting the area with water.
処理液(X)を繊維製品に塗布した後、水と接触するまでの放置時間は30分以上であり、1時間以上が好ましく、2時間以上がより好ましく、6時間以上がさらに好ましい。放置時間の上限値は特に制限されないが、例えば168時間(1週間)以下が好ましい。放置時間が上記下限値以上であると抗菌作用による防臭効果に優れる。

なお、放置前後の繊維製品の重さを測定し、その差(減少量)を蒸発した水分量とみなして、放置終了時の処理液(X)中の水の含有量を求めることができる。
After the treatment liquid (X) is applied to the textile product, the time for leaving it to stand before contacting it with water is 30 minutes or more, preferably 1 hour or more, more preferably 2 hours or more, and even more preferably 6 hours or more. The upper limit of the time for leaving it to stand is not particularly limited, but for example, 168 hours (1 week) or less is preferable. When the time for leaving it to stand is the above-mentioned lower limit or more, the deodorizing effect due to the antibacterial action is excellent.
At the end of the standing period, i.e., immediately before contact with water, the water content in the treatment liquid (X) applied to the textile product is preferably 40 mass % or less, more preferably 20 mass % or less, and even more preferably 10 mass % or less.
The weight of the textile product before and after being left standing can be measured, and the difference (reduction) can be regarded as the amount of water evaporated, to determine the water content in the treatment liquid (X) at the end of being left standing.
塗布後の放置時の環境については特に制限されないが、温度は5~40℃が好ましく、10~35℃がより好ましく、15~30℃がさらに好ましい。相対湿度は90%以下が好ましく、70%以下がより好ましく、50%以下がより好ましい。相対湿度の下限値については特に制限されないが、例えば湿度は15%以上が好ましい。

The relative humidity is preferably 90% or less, more preferably 70% or less, and even more preferably 50% or less. The lower limit of the relative humidity is not particularly limited, but for example, the humidity is preferably 15% or more.

(加水処理)
加水処理は、放置工程を終えた繊維製品を水と接触させる操作を含む処理である。

The water-adding treatment is a treatment including an operation of contacting the textile product that has been left standing with water.
It is preferable to bring the textile product into contact with water so that the water penetrates at least the portion of the textile product to which the treatment liquid (X) has been applied, and it is more preferable to bring the textile product into contact with water so that the water penetrates the entire textile product.
The water addition treatment preferably includes a rinsing step, and may include a cleaning step before the rinsing step.
すすぎ工程は放置工程後の繊維製品を、水ですすぐ工程である。例えば、繊維製品を水に浸してもよく、流水で流してもよい。すすぎ工程において、繊維製品に攪拌等の機械力をかけてもよい。 The rinsing process is a process in which the textile product after the leaving process is rinsed with water. For example, the textile product may be immersed in water or rinsed under running water. In the rinsing process, mechanical force such as stirring may be applied to the textile product.
洗浄工程は、界面活性剤を含む液体洗浄剤(Z)及び水を用いて、放置工程後の繊維製品を洗浄(洗濯)する工程である。
洗浄工程は、液体洗浄剤(Z)を含む洗浄液中で、好ましくは繊維製品に外力を加えて、繊維製品の汚れを洗浄液中に移行させた後、脱水等を行って、繊維製品を洗浄液から分離することが好ましい。洗浄工程後に前記すすぎ工程を行うことが好ましい。
洗浄工程において、繊維製品に外力を加える方法は、例えば洗濯機により機械力を加える方法でもよく、もみ洗い、押し洗い、たたき洗い、つかみ洗い、つまみ洗い、又は振り洗い等の手洗いによる方法でもよい。
The cleaning step is a step of cleaning (washing) the textile product after the leaving step using a liquid detergent (Z) containing a surfactant and water.
In the washing step, preferably an external force is applied to the textile product in a washing liquid containing the liquid detergent (Z) to transfer the dirt on the textile product into the washing liquid, and then the textile product is separated from the washing liquid by dehydration or the like. It is preferable to carry out the rinsing step after the washing step.
In the washing step, the method of applying an external force to the textile product may be, for example, a method of applying mechanical force using a washing machine, or a method of hand washing such as rubbing washing, pressing washing, beating washing, grabbing washing, pinching washing, or shaking washing.
洗浄工程で用いる液体洗浄剤(Z)は、界面活性剤を含むものであれば特に制限されず、公知の繊維製品用の洗浄剤を用いることができる。液体洗浄剤(Z)は処理液(X)と組成が異なることが好ましい。液体洗浄剤(Z)は市販品でもよい。 The liquid detergent (Z) used in the cleaning process is not particularly limited as long as it contains a surfactant, and any known detergent for textile products can be used. It is preferable that the liquid detergent (Z) has a different composition from the treatment liquid (X). The liquid detergent (Z) may be a commercially available product.
加水処理後、必要に応じて脱水、乾燥等を行い、繊維製品から水分を除去することにより、防臭効果が付与された(防臭処理された)繊維製品が得られる。 After the hydration treatment, dehydration, drying, etc. are performed as necessary to remove moisture from the textile product, resulting in a textile product that has been given a deodorizing effect (deodorizing treated).
<処理液(X)の製造方法>
処理液(X)は、(A)成分と(B)成分と水と、必要に応じた任意成分を、(A)成分の含有量が0.0001~0.1質量%である所定の組成となるように混合する方法で製造できる。
または、(A)成分と(B)成分を含有し、(A)成分の含有量が0.1質量%より高い処理液(Q)を希釈して処理液(X)を製造してもよい。
すなわち、本実施形態の処理方法は、塗布工程の前に、処理液(Q)を希釈して処理液(X)を調製する工程を有してもよい。
処理液(Q)を水で希釈して処理液(X)を調製することが好ましい。
<Method for producing treatment liquid (X)>
The treatment liquid (X) can be produced by a method of mixing the component (A), the component (B), water, and, if necessary, any optional components, so as to obtain a predetermined composition in which the content of the component (A) is 0.0001 to 0.1 mass %.
Alternatively, treatment liquid (X) may be produced by diluting treatment liquid (Q) which contains components (A) and (B) and has a content of component (A) of more than 0.1 mass %.
That is, the processing method of this embodiment may include a step of diluting the processing liquid (Q) to prepare the processing liquid (X) prior to the coating step.
It is preferable to prepare the treatment liquid (X) by diluting the treatment liquid (Q) with water.
本実施形態の処理方法によれば、繊維製品(被処理物)に処理液(X)を塗布した後、30分以上放置することにより、A成分の使用量が少なくても、優れた防臭効果を得ることができる。後述の実施例に示されるように、処理液(X)の組成が同じ場合に放置時間が長くなるほど防臭効果が向上する。
かかる効果が得られる理由について以下が考えられる。
放置工程において、繊維製品に塗布された処理液(X)中の水分が揮発することにより(A)成分の濃度が高まる。その結果、(A)成分が繊維製品に吸着されやすくなり、繊維製品の処理に使用する処理液(X)中の(A)成分の濃度が低くても、抗菌作用による防臭効果を充分に発揮できると考えられる。
According to the treatment method of this embodiment, by applying the treatment liquid (X) to a textile product (subject to be treated) and leaving it for 30 minutes or more, it is possible to obtain an excellent deodorizing effect even with a small amount of component A. As will be shown in the examples described later, when the composition of the treatment liquid (X) is the same, the longer the leaving time, the more improved the deodorizing effect becomes.
The reasons why such an effect is obtained are considered to be as follows.
In the leaving step, the water in the treatment liquid (X) applied to the textile product evaporates, increasing the concentration of the component (A). As a result, the component (A) becomes more easily adsorbed by the textile product, and it is considered that even if the concentration of the component (A) in the treatment liquid (X) used to treat the textile product is low, the deodorizing effect due to the antibacterial action can be sufficiently exhibited.
また、本発明者等は、可溶化剤(B)として特定のノニオン界面活性剤(B-2-2)を用いると、防臭効果が低下する傾向があることを知見した。その理由としては、放置中に処理液(X)中の水が揮発すると、(B-2-2)成分の濃度が高まってミセルを形成しやすくなり、(A)成分がミセルに取り込まれた状態が生じるためと考えられる。(A)成分を取り込んだミセルは繊維製品上に残り難く、加水処理時に除去されやすいため、(A)成分が効率良く繊維製品に吸着できないと考えられる。 The inventors have also found that the deodorizing effect tends to decrease when a specific nonionic surfactant (B-2-2) is used as the solubilizer (B). The reason for this is believed to be that when the water in the treatment solution (X) evaporates while the solution is left standing, the concentration of the (B-2-2) component increases, making it easier to form micelles, resulting in a state in which the (A) component is incorporated into the micelles. Micelles that have incorporated the (A) component are unlikely to remain on the textile product and are easily removed during the water treatment, so it is believed that the (A) component cannot be efficiently adsorbed to the textile product.
処理液(X)の好ましい態様として以下が挙げられる。
態様1:(A)成分と(B)成分と水とを含み、(A)成分がダイクロサンを含み、(B)成分が(B-1)成分と(B-2-1)成分を含み、

[Preparation Example 1: Synthesis of (B-2-1)-1 Component]
In a 4-L autoclave, 400 g of Procter &Gamble's CO1270 alcohol (a mixture of a 75/25 mass ratio of a carbon number 12 alcohol and a carbon number 14 alcohol) was charged as a raw material alcohol, and 0.8 g of potassium hydroxide catalyst was charged as a reaction catalyst. The inside of the autoclave was replaced with nitrogen, and the temperature was raised while stirring. Next, 91 g of ethylene oxide was introduced while maintaining the temperature at 180° C. and the pressure at 0.3 MPa or less, and the reaction was carried out to obtain an alcohol ethoxylate. Analysis was performed using a gas chromatograph: Hewlett-Packard's GC-5890, a detector: a flame ionization detector (FID), and a column: Ultra-1 (HP, L25 m×φ0.2 mm×T0.11 μm), and the obtained alcohol ethoxylate had an average added mole number of ethylene oxide of 1.0. In addition, the amount of the compound to which ethylene oxide was not added (the one that finally became the component (a0)) was 43% by mass based on the total amount of the obtained alcohol ethoxylate. Next, 237 g of the alcohol ethoxylate obtained above was placed in a 500 mL flask equipped with a stirrer, and after replacing with nitrogen, 96 g of liquid sulfuric anhydride (sulfane) was slowly added dropwise while maintaining the reaction temperature at 40°C. After the end of the dropwise addition, stirring was continued for 1 hour (sulfation reaction), and polyoxyethylene alkyl ether sulfate was obtained. Next, this was neutralized with an aqueous sodium hydroxide solution to obtain (B-2-1)-1.

各例の処理液(X)を用い、表に示す処理条件(処理方法A又はB、放置時間)で洗濯し、下記の方法で防臭効果を評価した。臭気強度の平均点と、防臭効果の判定結果を表に示す。 Using the treatment solution (X) of each example, laundry was performed under the treatment conditions shown in the table (treatment method A or B, leaving time) and the deodorizing effect was evaluated using the method below. The average odor intensity score and the deodorizing effect evaluation results are shown in the table.
(処理方法A)
新品の靴下(ユニクロ製スーピマコットンカノコソックス)に、各例の処理液(X)を片足7.5g(100%o.w.f.)ずつ塗布した後、所定時間放置した。放置時間(5分間、0.5時間、2時間、又は6時間)を表に示す。
次に、全自動電気洗濯機(Haier社製、製品名「JW-K33F(W)」)に、前記靴下、及び約750gの綿肌シャツ(B.V.D.社製)を投入した[浴比(洗濯水量/被洗布総質量)30倍]。
次に、前記全自動電気洗濯機に、市販の液体洗浄剤(Z-1)(ライオン株式会社製「トップ スーパーNANOX」)を標準使用量(10g/水30L)加え、標準コースで洗濯(洗浄、すすぎ、脱水)した。その際、洗浄時間、すすぎ、脱水、水量(低水位に設定、水量約15L)に関しては一切調整せず、洗濯機の標準コース設定をそのまま使用した。
洗濯処理終了後、前記靴下を取り出し、室温に放置して乾燥させた。
(Processing method A)
7.5 g (100% owf) of each treatment solution (X) was applied to each pair of new socks (Uniqlo Supima cotton pique socks) and then left for a predetermined time. The time allowed to stand (5 minutes, 0.5 hours, 2 hours, or 6 hours) is shown in the table.
Next, the socks and about 750 g of a cotton shirt (manufactured by B.V.D.) were placed in a fully automatic electric washing machine (manufactured by Haier, product name "JW-K33F(W)") [bath ratio (amount of washing water/total mass of fabric to be washed) 30 times].
Next, a standard amount (10 g/30 L of water) of a commercially available liquid detergent (Z-1) ("TOP SUPER NANOX" manufactured by Lion Corporation) was added to the fully automatic electric washing machine, and the laundry was washed (washed, rinsed, and dehydrated) on the standard course. At that time, the washing time, rinsing, dehydration, and water volume (set to low water level, water volume of about 15 L) were not adjusted at all, and the standard course settings of the washing machine were used as they were.
After the washing process was completed, the socks were taken out and left to dry at room temperature.
(処理方法B)
処理方法Aにおいて、市販の液体洗浄剤(Z-1)を用いず、水だけで前記洗濯を行った以外は、処理方法Aと同様にした。
(Processing method B)
The same procedure as in treatment method A was followed, except that the commercially available liquid detergent (Z-1) was not used and the washing was carried out using only water.
(防臭効果の評価方法)
処理後の靴下を8時間着用した後、専門パネル10名が下記の採点基準で臭気強度を採点した。10名の平均値を算出し、下記の判定基準で防臭効果を判定した。
[臭気強度の採点基準]
5点:強烈なニオイ。
4点:強いニオイ。
3点:楽に感知できるニオイ。
2点:何のニオイであるかわかる弱いニオイ。
1点:やっと感知できるニオイ。
0点:無臭。
[防臭効果の評価基準]
◎:臭気強度の平均点が2.0未満。
〇:臭気強度の平均点が2.0以上3.5未満。
×:臭気強度の平均点が3.5以上。
(Method of evaluating deodorizing effect)
After wearing the treated socks for 8 hours, 10 expert panelists rated the odor intensity according to the following criteria. The average score of the 10 panelists was calculated, and the deodorizing effect was evaluated according to the following criteria.
[Odor Intensity Scoring Criteria]
5 points: Strong odor.
4 points: Strong odor.
3 points: Easily detectable odor.
2 points: A faint odor that is easy to tell what it is.
1 point: Barely detectable odor.
0 points: Odorless.
[Evaluation criteria for deodorizing effect]
⊚: The average odor intensity score is less than 2.0.
Good: The average odor intensity score was 2.0 or more and less than 3.5.
×: The average odor intensity score is 3.5 or more.
表1~6の結果に示されるように、例1~29では繊維製品に良好な防臭効果が付与された。処理方法A及び処理方法Bでほぼ同等の効果が得られた。
塗付後の放置時間が5分間と短い例30は、防臭効果が不充分であった。
処理液(X)が抗菌剤(A)を含まない例31は、防臭効果がほとんど得られなかった。
処理液(X)が可溶化剤(B)を含まない例32は、防臭効果が不充分であった。この例では、処理液(X)において、抗菌剤(A)が水に溶けた状態となっていないため、塗布後6時間放置しても、抗菌剤(A)が繊維製品に充分に吸着されなかったと考えられる。
ノニオン界面活性剤(B-2-2)成分の含有量が10質量%を超える例33~35は、防臭効果が不充分であった。抗菌剤(A)がノニオン界面活性剤(B-2-2)のミセルに取り込まれてしまい、抗菌剤(A)が繊維製品に充分に吸着されなかったと考えられる。
As shown in the results in Tables 1 to 6, a good deodorizing effect was imparted to the textile products in Examples 1 to 29. Treatment method A and treatment method B provided substantially the same effect.
In Example 30, in which the standing time after application was as short as 5 minutes, the deodorizing effect was insufficient.
In Example 31 in which the treatment liquid (X) did not contain the antibacterial agent (A), almost no deodorizing effect was obtained.
Example 32, in which the treatment liquid (X) did not contain the solubilizer (B), had an insufficient deodorizing effect. In this example, it is believed that the antibacterial agent (A) was not dissolved in water in the treatment liquid (X), and therefore the antibacterial agent (A) was not sufficiently adsorbed onto the textile product even after being left for 6 hours after application.
Examples 33 to 35, in which the content of the nonionic surfactant (B-2-2) component exceeded 10% by mass, had insufficient deodorizing effect. It is believed that the antibacterial agent (A) was taken up into the micelles of the nonionic surfactant (B-2-2), and the antibacterial agent (A) was not sufficiently adsorbed to the textile product.
