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 sizing agent for fibers 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. Sho 60-4).
No. 5684), a paste for spray laundry paste containing a (meth) acrylate-based polymer emulsion having a particle size of 0.1 μm or less, modified starch, silicone oil emulsion and other additives (JP-A-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 comprising water-soluble silicone obtained by copolymerizing polyoxyethylene with an organopolysiloxane or anionizing or cationizing and water (JP-A-58-1983). 18476
No.). However, since the water-soluble silicone used in this finishing agent has dimethylpolysiloxane as a main skeleton and polyoxyethylene introduced into the side chain to make it water-soluble, it is separated from the water-soluble polymer paste. Although the above problem was solved, there was a problem that the slip of the iron became worse.

[0007]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a finishing agent 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.

In view of such a situation, the present inventors have conducted intensive studies and as a result, have found that a block copolymer having a repeating portion of dimethylpolysiloxane and a specific polyoxyethylene chain, a water-soluble polymer paste, It has been found that a combination of the above can provide a finishing agent for clothing suitable for manual spraying that does not cause separation and has good iron sliding, and has completed the present invention.

That is, the present invention provides the following component (a):

Carboxymethyl cellulose, polystyrene sulfonic acid or a salt thereof is particularly preferred.

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