DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finishing agent for clothing which has excellent long-term stability and good iron sliding, and is suitable for spraying, especially for manual spraying.

[0002]

2. Description of the Related Art There are various types of finishing agents for clothing mainly containing household paste, such as powders, liquids, gels and sprays.
Of these, spray-type clothing finishes are particularly convenient because they can be used partially and easily. Conventionally, spray-type clothing finishes have been added to LPG, D
The aerosol type, in which a propellant such as ME is charged and sprayed, is mainly used.

As the aerosol type, for example, an aerosol sizing composition containing a modified starch, a silicone oil emulsion and an alkylamine salt (JP-A-53-7)
No. 0190), a fiber composition comprising an intimate mixture of an aqueous solution of a water-soluble polymer paste and an emulsified or solubilized silicone oil having a viscosity of 500 cps or less (Japanese Patent Application Laid-Open No. 60-1985).
No. 45684), a paste for laundry paste containing a (meth) acrylate polymer emulsion having a particle diameter of 0.1 μm or less, modified starch, silicone oil emulsion and other additives (Japanese Patent Application Laid-Open No. 60-110975). Gazette).

However, the composition of these aerosol-type pastes is generally a non-uniform aqueous solution of a polymer paste which imparts tension and silicone as a slipping agent, and has a drawback that it is easily separated. Therefore, in the case of the aerosol type, the can had to be shaken before use.

On the other hand, cans filled with an aerosol type paste are:
There is a problem such as corrosion of the can due to the paste aqueous solution, lack of aerosol spray jet gas due to inversion or sideways use, and the can is disposable, so that effective use of resources cannot be achieved.
Further, in the case of the aerosol type, since high-pressure gas is used, it is not suitable for home use. In order to eliminate these drawbacks, development of a finishing agent for clothing using a manual spray without using a high-pressure gas has been desired. In this case, however, the problem of separation of a non-uniform aqueous solution has been further increased due to the trouble of shaking. Become serious.

[0006] In order to solve this separation problem,
There is a water-soluble paste, an ironing agent for clothing containing water-soluble silicone obtained by copolymerizing polyoxyethylene with an organopolysiloxane or anionizing or cationizing and water (Japanese Patent Laid-Open No. 58-1983). 18478
No.). However, this finish has a disadvantage that the slip of the iron is not good because the water-soluble silicone is used.

[0007]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a finish for clothing which is stable for a long period of time without causing separation of the composition and which is suitable for manual spraying with good iron sliding. is there.

[0008]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies in view of the above situation, and as a result, have combined an emulsion with a water-insoluble silicone having a particle diameter within a certain range with a water-soluble polymer paste. As a result, the present inventors have found that a finishing agent for clothing suitable for manual spraying, which does not cause separation and has good iron sliding, is obtained, and completed the present invention.

That is, the present invention provides the following component (a):
(B) and (c) (a) One or more water-soluble polymer pastes selected from hydroxyalkylated starch, carboxymethylcellulose, and polystyrenesulfonic acid and salts thereof: 0.1
(B) dimethylpolysiloxane having a dispersed particle size of 0.005 to 0.1 μm: 0.005 to 1% by weight (c) water; It provides a finishing agent.

[0010]

When a hydroxyalkylated starch is used as the component (a), it is preferable to use one having a degree of substitution of 0.08 to 0.3, particularly 0.1 to 0.2. When the degree of substitution is less than 0.08, a precipitate is formed over a long period of storage due to denaturation of the hydroxyalkylated starch, and the whitening phenomenon becomes more severe when used for colored clothing. Further, it is not preferable to use a material having a degree of substitution of more than 0.3, since a tendency of decreasing the tensile strength is observed. The viscosity of the aqueous solution of hydroxyalkylated starch can be reduced by decomposing the hydroxyalkylated starch with an oxidizing agent such as hydrogen peroxide, sodium hypochlorite or an enzyme, for example, 5% by weight (hereinafter “%”). In the aqueous solution)
It is preferably set to 40 centipoise (hereinafter referred to as “cp”) (20 ° C.) or less. If the viscosity is higher than this, the sprayability is not good, and as a result, the whitening phenomenon easily occurs.

When carboxymethylcellulose is used as the component (a), its degree of etherification is 0.6 to 0.6.
1.5, particularly preferably in the range of 0.8 to 1.0,
The viscosity of the 1% aqueous solution is 100 cp or less, especially 50 cp
The following are preferred. Further, when polystyrene sulfonic acid or a salt thereof is used as the component (a), the molecular weight is preferably 10,000 to 1.2 million, particularly preferably 50,000 to 600,000. Component (a) is added in an amount of 0.1 to 10 in the total composition.
%, But preferably 0.3 to 5%.

The dimethylpolysiloxane of the component (b) is
The particle diameter of the dispersed particles is 0.001 to 1 μm, preferably 0.001 to 0.5 μm, more preferably 0.001 to 0.5 μm.
5 to 0.1 μm. For particles larger than 1 μm,
Separation may occur, which is not preferable. The dimethylpolysiloxane is preferably incorporated in the form of an emulsion in which the above particles are dispersed. This emulsion is obtained by emulsification using an anionic surfactant, a nonionic surfactant or a cationic surfactant, but when dimethylpolysiloxane is obtained by emulsion polymerization, The emulsified state can be used as it is. The amount of the surfactant used for emulsification is from 10 to 60%, especially from 15 to 60%, based on dimethylpolysiloxane.
Preferably, it is 45%. The amount of dimethylpolysiloxane to be added to the finishing agent for clothing of the present invention is preferably 0.005 to 1%, particularly preferably 0.05 to 0.5%. A viscosity of 100 cp containing 35% dimethylpolysiloxane as a solid content.
It is particularly preferable to mix the emulsion as follows (at 25 ° C.).

The ironing agent for clothing of the present invention further increases the storage stability by incorporating a surfactant in an amount of 0.05 to 5%, preferably 0.02 to 1%, in addition to the above components. Can be. Examples of the surfactant include a polyoxyethylene alkyl or alkenyl ether having an alkyl group or an alkenyl group having an average of 10 to 20 carbon atoms, and having 1 to 20 mol of ethylene oxide added thereto, and an alkyl group having an average carbon number of 9 to 13. A polyoxyethylene alkyl phenyl ether to which 1 to 20 moles of ethylene oxide is added, an alkyl glycoside having an alkyl group having an average carbon number of 8 to 18 and a sugar polymerization degree of 1.1 to 3.0. Nonionic surfactant; alkyl sulfate having an alkyl group having an average of 10 to 20 carbon atoms, and an average of 10 to 10 carbon atoms
Alkyl ether sulfate having 20 alkyl groups and 1 to 8 mol of ethylene oxide added, average carbon number 1
0-20 olefin sulfonate, average carbon number 10-10
Anionic surfactants such as an alkanesulfonic acid salt of 20 and an alkylbenzenesulfonic acid salt having an alkyl group having an average of 10 to 16 carbon atoms are exemplified. Of these, polyoxyethylene alkyl or alkenyl ether is preferred.

The finishing agent for clothing of the present invention may further comprise, if necessary, an organic acid such as citric acid, malic acid, benzoic acid or tartaric acid, an iron adhesion preventing agent such as polyethylene glycol, glycerin or polypropylene glycol, ethyl alcohol, Solvents such as propyl alcohol and propylene glycol, fluorescent dyes, antibacterial agents, bactericides, and fragrances can be added.
