[Method for producing fiber treatment composition]
In the composition of the present invention, an O / W type emulsified form is preferable in that the adsorption of the component (a) to the target surface can be promoted. Further, an O / W type emulsion composition in which capsule-like particles containing the component (a) are dispersed with the component (b) as an outer shell is more preferable. This is thought to be because the hydrocarbon group in component (b) interacts with component (a) and efficiently emulsifies.

  Although it does not specifically limit as a manufacturing method of the composition of this invention, The method of following (1)-(3) is mentioned.

(1) Normal phase emulsification method At room temperature, the component (b), if necessary, the component (d1), the component (d2), the component (e), and an appropriate amount of the component (c) are mixed. The mixture is stirred at ° C to disperse component (b) in component (c), and then cooled to room temperature (this solution is referred to as (F)). Next, if necessary, the component (d1), the component (d2), and the component (e) are added and mixed with stirring. Thereafter, the component (a) is slowly dropped while stirring with a homomixer. In the case where the component (a) is solid at normal temperature or does not flow, it is desirable to add it after heating it to the melting point or the pour point. In that case, the solution (F) is also preferably heated to a temperature higher than the melting point or pour point of the component (a). After the addition, the mixture is further stirred with a homomixer, and the remaining component (c) is added and stirred. Moreover, pH adjustment is carried out as needed and the oil-in-water emulsion of this invention is obtained.

(2) Phase inversion emulsification method At room temperature, the component (b) is mixed with the component (d1), the component (d2), the component (e), and the component (a) as necessary. The component (b) is dispersed in the component (a). In the case where the component (a) is solid at normal temperature or does not flow, it is desirable that the component is heated to the melting point or pour point and stirred. After stirring, cool to 50 ° C., add component (d1), component (d2), and component (e) as necessary, mix with stirring, and then mix component (c) with stirring with a homomixer or propeller. Slowly drop. Also in this case, when the component (a) is solid at normal temperature or does not flow, it is desirable to heat the component more than the melting point or pour point and slowly drop the component (c). After the addition, the mixture is further stirred and then cooled to room temperature, and the pH is adjusted as necessary to obtain the oil-in-water emulsion of the present invention.

(3) Gel emulsification method At room temperature, add the component (b), if necessary, the component (d1), the component (d2), and the component (e) to the component (c) equivalent to 15% of the required amount, Next, after heating, the mixture is stirred at 80 ° C. and then cooled to 25 ° C. (this solution is referred to as (G)). Next, if necessary, the components (d1) and (d2) are added with stirring, and the mixture is left to stir. Thereafter, the component (a) is slowly added. In the case where the component (a) is solid at normal temperature or does not flow, it is desirable to add it after heating it to the melting point or the pour point. In that case, the solution (G) is also preferably heated to a temperature equal to or higher than the melting point or pour point of the component (a). After the addition, the mixture is further stirred, and then the temperature of the blend is raised to 60 ° C. or higher than the melting point or pour point of the component (a), and further stirred to obtain a mixture. Cool to the same temperature or, if necessary, about 40 ° C., slowly add the remaining component (c) to the mixture obtained by the above method and stir. Moreover, after adjusting pH as needed, the temperature of a formulation is slowly lowered to normal temperature and the oil-in-water emulsion of this invention is obtained. In this production method, a part of the component (a) may be added together with the component (b). Moreover, it is suitable to adjust the solution of (G) to 20-75 degreeC, Preferably it is 30-60 degreeC, and mixes the water of (c) at 20-90 degreeC, Preferably it is 30-70 degreeC. The component (d1) and the component (d2) may be added in advance to the solution (G), may be dissolved in advance in the component (e), and further after the solution (G) and the component (c) are mixed. It can be added.

  According to the method as described above, an oil-in-water emulsion containing capsule-shaped particles having a particle size of 0.1 to 50 μm in which the component (b) is an outer shell and the component (a) is encapsulated is obtained.

  In the present invention, it is possible to provide a fiber treatment agent composition comprising an oil-in-water emulsion containing a hydrophobic compound. According to the present invention, the emulsification is not broken by dilution, and the hydrophobic compound is efficiently applied to the target surface. Can be adsorbed.
