TECHNICAL FIELD OF THE INVENTION The present invention relates to a fiber finish composition. More specifically, the present invention relates to a paste composition for spraying, which is used by filling a manual spray container such as a trigger sprayer.

2. Description of the Related Art In recent years, a sizing agent containing a polymer component has been widely used in general households as a fiber finishing agent.
Many types of products such as gel and spray are commercially available. Of these products, the spray type, particularly the aerosol type sizing agent, tends to be preferred because it is easy and convenient to use, but this aerosol type sizing agent has the drawback of poor iron adhesion and iron slipperiness. there were.
In order to solve these drawbacks, improvements have been made in aerosol type sizing agents and iron slip agents. For example, a water-soluble polymer sizing agent aqueous solution and an emulsified or solubilized viscosity 50

However, in spite of such development efforts, in the aerosol type sizing agent, the dispersion of the polymer sizing agent which generally gives tension to the fiber product and the silicone which is a slipping agent is nonuniformly separated. There are drawbacks that it is easy, the jetting gas is deficient while the paste remains, it is not suitable for home because high pressure gas is used, and the container becomes disposable, which is against the effective use of resources. In order to eliminate such drawbacks, a sizing agent using a manual spray has been developed, and for example, an aqueous solution obtained by copolymerizing polyoxyethylene with an organopolysiloxane, or anionizing or cationizing it. Ironing agent for clothes, which contains water-soluble silicone and water (Japanese Patent Laid-Open No. 58-18478).

39774). However, since the water-soluble silicone is also used for the sizing agent using this manual spray, the iron slip is not good, and the stability of the composition is poor because the content of the water-insoluble component is However, there are some drawbacks such as the fact that it is scattered by the spray and makes the floor slippery.

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a sizing agent composition which is stable for a long period of time without separation of components and has a good iron slipping property, particularly a sizing agent composition suitable for manual spraying. To provide.

[0005]

[Means for Solving the Problems] The present inventors have conducted research to improve the drawbacks of conventional paste compositions and to obtain excellent paste compositions. Even without using a slip agent, by limiting the pH to a specific range, good lubricity can be obtained when ironed after being applied to a textile product by a manual spray,
It has been found that ironing workability is remarkably improved, and at the same time, a long-term stable manual spray paste composition can be obtained. The present invention has been completed based on such findings. Therefore, the present invention contains 0.1 to 20% by weight of an acid and / or salt of a water-soluble polymer having a carboxyl group and a molecular weight of 2,000 to 6,000,000, and having a pH of 3.5.
The present invention provides a sizing agent composition for spraying, which comprises an aqueous solution of about 7.5.

The acid of the water-soluble polymer used in the present invention and /
Or, examples of salts include carboxyalkylated starches such as carboxymethylated starches, and modified starches whose viscosity is reduced with an oxidizing agent or enzyme such as hydrogen peroxide, sodium hypochlorite; carboxymethyl cellulose, acrylic acid. , Methacrylic acid, maleic acid, polymers or copolymers of maleic anhydride or the like, or salts thereof, in particular acrylic acid, methacrylic acid, maleic acid, a polymer or copolymer of maleic anhydride, or the like, or These salts are preferred. When using modified starch, the degree of substitution is
It is preferably 0.08 to 0.3, particularly 0.1 to 0.2. The reason for defining the degree of substitution in this way is that if the degree of substitution is less than 0.08, a precipitate is formed due to the modification of the modified starch when it is stored for a long period of time, and the whitening phenomenon when used for clothing of colored items becomes more severe. If it is larger than 0.3, the tensile strength tends to decrease, which is not preferable. The viscosity of the aqueous solution of the modified starch can be lowered by decomposing the modified starch with an oxidizing agent such as hydrogen peroxide or sodium hypochlorite or an enzyme. For example, a 5 wt% aqueous solution has a good viscosity of 40 centipoise (hereinafter referred to as cp) or less at 20 ° C., and a viscosity of more than this value is not good in sprayability, and as a result, the whitening phenomenon easily occurs.

When carboxymethyl cellulose is used, its degree of etherification is 0.6 to 1.5, especially 0.8 to.
The range of 1.0 is preferable, and the viscosity of the 1% aqueous solution is preferably 100 cp or less, and particularly preferably 50 cp or less.
Further, in the present invention, the molecular weight of the acid and salt of the water-soluble polymer is preferably in the range of 2,000 to 6,000,000, particularly 10,000 to 600,000. The reason for defining the molecular weight in this way is that if it is less than 2,000, good elasticity cannot be given to the fiber, while if it exceeds 6,000,000, clogging occurs near the injection port of the aerosol, or the fiber exceeds the necessary amount. It is not preferable because it gives firmness. The amount of the water-soluble polymer of the present invention, based on the weight of the paste composition,
It is preferably 0.1 to 20% by weight, particularly preferably 0.5 to 8% by weight. The reason for defining the blending amount in this way is that if the amount is less than 0.1%, it is not possible to provide the fiber with favorable elasticity, while if it exceeds 10%, clogging occurs near the trigger injection port, This is because it is not preferable because it gives more tension than necessary.

Further, according to the present invention, the pH of the sizing composition is set to 3.5 to
It is preferably set at 8, particularly 4.0 to 7.5. Like this p
The reason for defining H is that when the pH is less than 3.5, the high-molecular polymer forms a film with strong adhesiveness and adheres to the iron to deteriorate ironing workability, while the pH exceeds 8 This is because the alkalinity may cause troubles such as rough skin of the user. The alkaline substance used for adjusting the pH in the present invention is, as the cation, a compound containing an alkali metal such as sodium and potassium, an alkaline earth metal such as magnesium, ammonium and triethanolamine, for example, sodium. And triethanolamine are preferred.

If desired, the sizing composition of the present invention may contain a surface active agent in an amount of 0.05 to 5% by weight, preferably 0.02 to 1% by weight. The stability can be further increased. Examples of such a surfactant include a polyoxyethylene alkyl or alkenyl ether having an alkyl group or an alkenyl group having an average carbon number of 10 to 20 and having 1 to 20 mol of ethylene oxide added (provided that the polyoxyethylene alkyl or alkenyl ether of the present invention is (Other than component (b)), a polyoxyethylene alkylphenyl ether having an alkyl group having an average carbon number of 9 to 13 and having 1 to 20 mol of ethylene oxide added thereto, an alkyl having an average number of carbon atoms of 8 to 18 It has a group and the degree of sugar polymerization is 1.1 to 3.
A nonionic surfactant such as an alkyl glycoside of 0; an alkyl sulfate having an alkyl group having an average number of carbon atoms of 10 to 20, an alkyl group having an average number of carbon atoms of 10 to 20 and 1 to 8 mol of ethylene. Oxide-added alkyl ether sulfate, olefin sulfonate having an average number of carbon atoms of 10 to 20, alkane sulfonate having an average number of carbon atoms of 10 to 20, and an alkyl group having an average number of carbon atoms of 10 to 16 Examples include anionic surfactants such as alkylbenzene sulfonate. Furthermore, an additive can be added to the paste composition of the present invention as needed. For example, organic acids such as citric acid, malic acid, benzoic acid, tartaric acid, iron anti-sticking agents such as polyethylene glycol, glycerin, polypropylene glycol, solvents such as ethyl alcohol, propyl alcohol, propylene glycol, fluorescent dyes, antibacterial agents, sterilization Agents and fragrances.
