When a textile product such as clothing is washed, the textile product may become fluffy due to rubbing between textile products that are washing objects. When the fiber product becomes fluffy, the original texture of the fiber product is impaired.
For example, when a colored textile product is washed, if the colored textile product becomes fluffy, it tends to appear as faded. In addition, when washing both colored textile products and white textile products, if the white textile products become fluffy and fluffy fibers are missing and adhere to the colored textile products, the appearance of the colored textile products May be damaged.

In order to solve such a problem, a cleaning agent containing cellulase such as endoglucanase is known as a cleaning agent for removing fluff generated in the fiber product while cleaning the fiber product. Cellulase can cut fluff produced in cellulose-containing fibers (for example, cotton, hemp, rayon, or a blended fiber of these with other fibers) to prevent deterioration of the appearance of the fiber product.
For example, Patent Document 1 discloses the effect of cellulase (damaged cellulose by adding a water-soluble polymer obtained by polymerizing one or more monomers selected from the group consisting of vinyl pyrrolidone, vinyl alcohol, vinyl carboxylate, acrylamide and soluble acrylate. A technique for improving the fiber removal effect) is disclosed.
Proposals for cellulase preparations that contain fluffs produced in textile products include endoglucanase with cellulose binding domain and specific terephthalic acid-alkylene glycol polymer or terephthalic acid-oligoalkylene glycol alone or in combination (Patent Document 2). The invention of Patent Document 2 aims to improve the texture of cellulose-containing fibers by increasing endoglucanase activity.

According to the textile treatment liquid of the first aspect of the present invention and the textile treatment composition of the second aspect, the fluff of the textile can be removed better.

Details of the first and second aspects of the present invention will be described below.
In the present specification, the “fluff” means a fiber coming out from the surface of the fiber product, and is generated, for example, by friction between the fibers. In addition, in one aspect of the present invention, “fluff” refers to a fiber that emerges from the surface of a fiber product and has an amorphous portion in which the molecular arrangement of the fiber polymer is disturbed.

(First aspect: Textile treatment liquid)
The textile treatment liquid according to the first aspect of the present invention contains (A) component: endoglucanase and (B) component: one or more ions selected from the group consisting of calcium ions and magnesium ions.
Moreover, in one aspect of the present invention, the textile treatment liquid preferably includes the component (A), the component (B), and water.

<(A) component: endoglucanase>
In the textile treatment liquid of the first aspect of the present invention, the component (A) is endoglucanase. Endoglucanase is endo-1,4-β-glucanase EC 3.2.1.4, which is a cellulase having an action of hydrolyzing β-1,4-glucopyranosyl bond of β-1,4-glucan. . Component (A) comprises cellulose, cellulose derivatives (eg, carboxymethylcellulose, hydroxyethylcellulose), lichenin, β-1,4 bonds in β-1,3 glucan mixtures such as cereal β-D-glucan or xyloglucan And catalyze the internal hydrolysis of other plant materials containing cellulose moieties.

Examples of commercially available products of component (A) include Carezyme 4500L (trade name, manufactured by Novozymes), Carezyme Premium 4500L (trade name, manufactured by Novozymes), Endrase (trade name, manufactured by Novozymes), Cell Clean (product) Name, Novozymes, Inc.), among others, carezyme 4500L (product name) and carezyme premium 4500L (product name) are preferable, and carezyme premium 4500L (product name) is more preferable.
(A) A component may be used individually by 1 type and may be used in combination of 2 or more type.

(A) As a component, what has high enzyme activity (vs. non-crystalline activity) with respect to an amorphous cellulose is preferable. It is considered that the fluff produced by friction between fibers has many non-crystalline sites. For this reason, the higher the non-crystalline activity of the component (A), the more the fuzz removal effect can be improved.
The non-crystalline activity of the component (A) is preferably 30,000 to 90,000 units / mL, more preferably 60,000 to 90,000 units / mL.
Non-crystalline activity was measured by measuring the amount of Glu-like reducing terminal (μM) produced by the decomposition reaction of phosphoric acid-swelling cellulose, which is amorphous cellulose, based on the p-hydroxybenzoic acid hydrazine (PAHBAH) method. This is a value calculated from the amount of Glu-like reducing terminal (μM).
Specifically, it can measure by the measuring method mentioned later.
In the first aspect of the present invention, in this enzyme activity measurement method, the amount of enzyme that produces a reducing sugar corresponding to 1 μM glucose per minute is defined as 1 unit.

In addition, the ratio ([crystal] / [non-crystal] activity ratio) represented by [enzyme activity for crystalline cellulose (vs. crystal activity)] / [vs. Amorphous activity] in the component (A) is 0.05 to 0.3 is preferable, and 0.05 to 0.1 is more preferable. Removal of fuzz requires a certain degree of crystalline decomposition as well as non-crystalline decomposition. When the [Crystal] / [Non-Crystal] activity ratio exceeds the above upper limit value, it is easier to promote the degradation of the fiber product than the fuzz removal effect. If it is less than the lower limit, decomposition of only the non-crystalline fluff is promoted, and the fluff crystalline remains. For this reason, the strength of the fluff is maintained, and the effect of removing the fluff tends to decrease. By setting the [crystal] / [non-crystal] activity ratio within the above range, it is possible to better prevent the fiber product from deteriorating while exhibiting a better fuzz removal effect.
Examples of the component (A) having a [crystal] / [non-crystal] activity ratio of 0.05 to 0.1 include CAREZYME 4500L and CAREZY Premium 4500L.

The anti-crystal activity was determined by measuring the amount of Glu-like reducing terminal (μM) produced by the decomposition reaction of crystalline cellulose in accordance with the p-hydroxybenzoic acid hydrazine (PAHBAH) method. It is a value calculated from the amount (μM).

The content of the component (A) in the fiber product treatment liquid according to the first aspect of the present invention is determined according to, for example, the amount of the fiber product to be treated, etc. 130,000 to 1,400,000 units, 200,000 to 1,100,000 units are more preferable, and 275,000 to 550,000 units are more preferable. If the amount is less than the above lower limit value, the fluff removal effect may be reduced. Become. That is, if the content of the component (A) in the textile treatment liquid according to the first aspect of the present invention is 130,000 to 1,400,000 units per 1 kg of textile products to be treated, high fluff It is preferable because it has a removing effect and there is no fear of deteriorating the textile product.
For example, in a drum-type washing machine for home use (7 kg capacity), the amount of textile products to be treated is 1 to 3 kg, and the necessary textile treatment liquid is 8 to 12 L. In a vertical washing machine for home use (capacity 7 kg), the amount of textile products to be processed is 1 to 3 kg, and the necessary textile processing liquid is 15 to 45 L. In a commercial drum-type washing machine (capacity 27 kg), the amount of textile products to be treated is 15 kg, and the necessary textile product treatment liquid is 60 to 90 L.
The concentration of the component (A) in the textile treatment liquid according to the first aspect of the present invention is preferably 15,000 to 350,000 units / L, and 22,000 to 300,000 units per liter of textile treatment liquid. / L is more preferable, and 35,000 to 150,000 unit / L is more preferable.
The unit “unit” of the component (A) content and concentration is non-crystalline activity. Moreover, the value with respect to the non-crystal activity of the said (A) component is a value in a textiles processing liquid. That is, it is a value of non-crystalline activity in a state where the activity is enhanced by the component (B) contained in the textile treatment liquid.

<(B) component: one or more ions selected from the group consisting of calcium ions and magnesium ions>
In the textile treatment liquid according to the first aspect of the present invention, the component (B) is one or more ions selected from the group consisting of calcium ions and magnesium ions. The component (B) can enhance the activity of the component (A) and can further enhance the fluff removal effect of the textile treatment liquid.
Examples of the supply source of calcium ions include water-soluble calcium compounds containing calcium such as calcium chloride, calcium sulfate, calcium acetate, and calcium oxalate, and water containing calcium ions at a high concentration.
Examples of the supply source of magnesium ions include water-soluble magnesium compounds such as magnesium chloride and magnesium sulfate, and water containing magnesium ions at a high concentration.
The supply source of these (B) components may be used individually by 1 type, and 2 or more types may be used in combination. Among these, as (B) component, it is preferable that it is an ion which uses calcium chloride and / or magnesium chloride as a supply source, and it is more preferable that it is calcium chloride.
In the first aspect of the present invention, when the textile treatment liquid contains tap water, the component (B) includes not only ions derived from the supply source, but also calcium ions contained in tap water. , Containing magnesium ions.
In the first aspect of the present invention, the component (B) is preferably calcium ion.

The lower limit of the concentration of the component (B) in the textile treatment liquid in the first aspect of the present invention is 20 mass ppm or more, preferably 30 mass ppm or more, based on the total mass of the textile treatment liquid. More preferable is ppm by mass or more, and further more preferable is 50 ppm by mass or more. If the amount is less than the above lower limit, the fluff removal effect cannot be improved.
The upper limit of the concentration of the component (B) in the textile treatment liquid in the first aspect of the present invention is 100 mass ppm or less, preferably 90 mass ppm or less, based on the total mass of the textile treatment liquid. The mass ppm or less is more preferable, and the mass ppm or less is more preferable. Above the upper limit, the effect of removing fuzz may be reduced due to inhibition of binding of the component (A) to the fiber, a decrease in reaction rate due to a decrease in the flexibility of the enzyme molecule, aggregation of the component (A), and the like.
That is, in the first aspect of the present invention, the concentration of the component (B) in the textile treatment liquid is 20 to 100 ppm by mass with respect to the total mass of the textile treatment liquid, and 30 to 90 ppm by mass. Preferably, 40 to 80 ppm by mass is more preferable, and 50 to 70 ppm by mass is particularly preferable. If the concentration of the component (B) in the textile treatment liquid is within the above range, a high fuzz removal effect is obtained, and the binding inhibition of the component (A) to the fiber and the flexibility of the enzyme molecule are reduced. This is preferable because the reaction rate is not easily lowered.

In the fiber product treatment liquid according to the first aspect of the present invention, a ratio represented by [(B) component concentration (mass ppm)] / [(A) component concentration (unit / L)] (hereinafter referred to as B / The A ratio) is preferably 0.0002 to 0.0019, more preferably 0.0006 to 0.0017, and still more preferably 0.0008 to 0.0014. If the amount is less than the lower limit, the fluff removal effect cannot be improved, and even if the upper limit is exceeded, the fluff removal effect cannot be further improved, which is economically undesirable.

The concentration of calcium ions in the textile treatment liquid in the first aspect of the present invention is measured, for example, by the following method. First, for a calcium ion standard solution having a predetermined concentration, a calibration curve is created by measuring the potential of the standard solution using a calcium electrode (Orion 9720BNWP). Next, the potential of the textile treatment liquid is measured for the textile treatment liquid using a calcium electrode, and the calcium ion concentration in the textile treatment liquid is calculated from the obtained value and the calibration curve.
When the textile treatment liquid contains an ion scavenger such as a chelating agent, the calcium ion concentration of the textile treatment liquid containing the ion scavenger is measured by the above method.

The concentration of magnesium ions in the textile treatment liquid according to the first aspect of the present invention is prepared in advance using, for example, a potential measured using a magnesium electrode (DX224-Mg of METTTLER TOLEDO) and a magnesium ion standard solution. It is calculated from the obtained calibration curve.

The textile treatment liquid in the first aspect of the present invention may contain one or more additives selected from the group consisting of component (C1): surfactant and silicone. By containing the component (C1), the fiber product treatment liquid can easily penetrate into the inside of the cellulose-containing fiber (permeation promoting effect), and the fluff cut by the component (A) is promptly put into the fiber product treatment solution. It is possible to suppress the fuzz from being dispersed and adhering to the fiber product (fuzz adhesion inhibitory effect).

The concentration of the component (C1) in the fiber product treatment liquid is determined in consideration of the type of the component (C1) and the like. For example, the concentration is preferably 20 ppm by mass or more with respect to the total mass of the fiber product treatment liquid. More preferred is ppm by mass, even more preferred is 25 to 1000 ppm by mass, and particularly preferred is 50 to 500 ppm by mass. If it is above the above lower limit value, the effect of promoting the penetration of the textile treatment liquid into the textile can be further enhanced, and the fluff cut by the component (A) can be well dispersed in the textile treatment liquid. It is possible to satisfactorily prevent the fluff from adhering to the textile product. Even if it exceeds the above upper limit value, the improvement of the fuzz removal effect and the fuzz adhesion suppression effect corresponding to it is not seen, which is disadvantageous economically. In addition, when a washing machine is used in the enzyme treatment step described later, if the amount exceeds the upper limit, foaming of the fiber product treatment liquid increases, the shearing force to the treatment target is reduced, and the fuzz removal effect may be reduced. .

When the textile treatment liquid contains the component (C1), the mass ratio represented by the mass of the ingredient (C1) / the mass of the ingredient (B) in the textile treatment liquid (hereinafter sometimes referred to as C1 / B ratio). ) Is preferably 0.4 to 16, more preferably 1.5 to 15, and still more preferably 2 to 5. When the C1 / B ratio exceeds the above upper limit, the content of the component (C1) becomes too large, and the component (A) becomes difficult to bind to the treatment target, or the component (A) is processed from the fiber product to the fiber product. There is a possibility that the fluff removal effect is lowered due to easy detachment into the liquid. If it is less than the lower limit, the component (C1) becomes too small, and the effect of promoting the penetration of the fiber product treatment liquid into the fiber product, the effect of dispersing the fluff, and the effect of preventing the reattachment of the fluff may be reduced. That is, it is preferable that the C1 / B ratio is 0.4 to 16, since the effect of promoting the penetration of the fiber product treatment liquid into the fiber product, the effect of fuzz dispersion, and the effect of preventing fluff reattachment are not lowered. In addition, the component (A) is preferable because it is difficult for the component (A) to be detached from the fiber product into the fiber product treatment liquid and easily binds to the treatment target.
