Description

Description: TECHNICAL FIELD The present invention relates to a shine removal agent containing a specific silicone compound having an effect of removing shine generated in clothing.

[Conventional technology and its problems]

When clothes such as suits, uniforms, boys' school uniforms, women's sailor suits, etc. are worn for a long period of time, shininess occurs on the elbows, knees, hips, etc., and a phenomenon that the appearance of the clothes is significantly impaired is often observed. Furthermore, shining may be generated on the surface by repeatedly ironing clothes.

The cause of the shine is that, due to long-term wearing or ironing, the fine irregularities of the woven structure on the fiber surface become flat due to the effect of friction and compression, and as a result, the reflectance of light incident on the fiber surface increases, This is because the fiber surface looks shiny. This phenomenon is particularly conspicuous in clothing with a low light reflectance and a dark color, and tends to occur in clothing using materials such as wool, wool / polyester blend, and wool / nylon blend.

As a measure to prevent the generation of shine, it is effective to apply ironing cloth and apply a steam iron when ironing to some extent, but it is not possible to completely prevent the generation of shine by such an operation. At present, it is possible that there is nothing to do with shiny generated as a result of wearing clothing.

As a treatment agent that imparts a unique texture and a special effect to an object to be treated, silicone has recently attracted more and more attention not only in the textile industry but also in all industrial fields. In recent years, not only dimethylpolysiloxane, which has been the most common in the past, but also various alkylpolysiloxanes, and various modified silicones in which various modifying groups have been introduced into the alkyl group portion, have been developed. Amino-modified silicones with amino groups introduced into them, ether-modified silicones with one or both ethylene oxide and propylene oxide groups introduced, hydrogen-modified silicones with alkyl groups replaced by hydrogen, and fluorine with alkyl fluoride groups introduced There are modified silicone, epoxy-modified silicone into which an epoxy group is introduced, and the like.

It has been reported that amino-modified silicones are particularly excellent in the adsorptivity to fibers and the film-thickness on the fiber surface among the various silicones described above, and have an anti-glare effect (JP-A-64-61576). However, since amino-modified silicone has too strong absorptivity to the fiber, once it is adsorbed on the fiber, it does not easily fall off in the usual washing treatment, and further, the treated surface turns yellow under the influence of heat and light on the clothing surface. There was a problem of yellowing, and it was not always suitable as a base for preventing shininess.

[Means for solving the problem]

The present inventors have found that it is possible to easily remove shine generated on clothing at home and, if necessary, with home washing, to remove shine from fibers that do not turn yellow on the treated fiber surface. As a result of intensive studies to find a composition, they have found that this object can be achieved by using an amino ether-modified silicone, and have completed the present invention.

That is, the present invention provides a composition for removing shine of fibers, comprising an aminoether-modified silicone or a mixture of an aminoether-modified silicone and an amino-modified silicone.

The amino ether-modified silicone is obtained by adding a structural unit represented by the following formula (B) to a silicone represented by the following formula (A) by m /
(L + m) is contained at a ratio of 0.005 or more, and a structural unit represented by the following formula (C) is contained at a ratio of n / (l + n) of 0.005 or more. The amino-modified silicone contains the structural unit represented by the formula (B) in the silicone represented by the formula (A) at a ratio of m / (l + m) of 0.005 or more.

[Wherein, R _{1 is a} hydrogen atom, a substituted or unsubstituted hydrocarbon group R ₂ :-[-(CH ₂ ) _X NH-] _a- (CH ₂ ) _Y -NH ₂ R ₃ :-(CH ₂ ) _X (OC ₂ H ₄ ) _b (OC ₃ H ₆ ) _c OR ₄ where a: 0 or an integer of 1 to 5 b and c: 0 or an integer of 1 to 50 (but not both 0) R ₄ : hydrogen or an alkyl group having 1 to 12 carbon atoms X and Y: 2 or 3 R: R ₁ , R ₂ , R ₃ , alkoxy group or hydroxy group l: 20 to 50000 m: 1 to 20000 n: 1 to 20000] In the above formulas, R ₁ is preferably hydrogen or an alkyl group, and a is preferably 0 to 2. Specifically, R ₁ is a methyl group, an ethyl group, a propyl group, a phenyl group or the like, but is usually a methyl group. R ₁ need not be all the same in one molecule.

R ₂ is — (CH ₂ ) ₃ —NH ₂ , — (CH ₂ ) ₃ NH— (CH ₂ ) ₂ —N
H _{2 and the} like, and R ₃ is — (CH ₂ ) ₃ — (OC ₂ H ₄ ) ₅ OH and the like. R ₄ is preferably hydrogen or an alkyl group having 1 to 12 carbon atoms, but usually hydrogen is generally used.

R is R ₁ , R ₂ , R ₃ , an alkoxy group or a hydroxy group, and a methoxy group is generally used as the alkoxy group.

l is in the range of 20 to 50,000, m is in the range of 1 to 20,000, n is in the range of 1 to 20,000, m / (l + m) is 0.005 to 0.5, preferably 0.005 to 0.25, and n / (l + n) is 0.005 to 0.5, Preferably it is 0.005 to 0.25. Also, l + m + n
Is suitable in the range of 20 to 50,000, l + m is suitable in the range of 20 to 50,000,
Particularly preferred modified silicones as shine removal composition components are those with l + m + n in the range of 100-8000 and l + m in the range of 100-8000.

In the shine removal composition of the present invention, the amount of the modified silicone is not particularly limited, but the total amount of the modified silicone is 0.1 to 5% by weight based on the weight of the clothing in any of immersion, handy spray, and aerosol spray. It is good to adhere. That is, in the case of the immersion treatment, the modified silicone is blended in a total amount of 5 to 60%, and when used, 5 to 5% with water.
It may be diluted 60 times, treated at a bath ratio of 1/10 to 1/30, and then dried. In the case of spraying with a handy spray or an aerosol, the modified silicone may be blended in a total amount of 0.2 to 5% in a liquid, the composition may be sprayed on clothing, and then dried.

The composition for removing shine of fibers of the present invention can be used for clothing using any of natural fibers, synthetic fibers and blended fibers.

When spraying the composition of the present invention in the form of a spray, LP
Conventional propellants such as G, n-butane, chlorofluorocarbon, carbon dioxide, and dimethyl ether can all be used.

The compounding ratio when amino-modified silicone and amino-modified silicone are used in combination can be set in the range of amino ether-modified silicone / amino-modified silicone = 1/100 to 100/1, but the preferable compounding ratio is amino-ether-modified silicone. / Amino-modified silicone = 1/1 to 10/1.

When a surfactant is added as a penetrating agent to the composition of the present invention, the modified silicone is quickly fixed on the fiber surface, and a uniform shine removal effect can be obtained. As the surfactant, a nonionic surfactant is suitable, and polyoxyethylene alkyl ether, polyoxyethylene alkenyl ether, polyoxyethylene alkylphenyl ether,
Polyoxyethylene sorbitan fatty acid esters and the like can be used, but polyoxyethylene alkyl ethers, which have particularly good permeability to fibers and can provide a uniform unevenness removing effect, specifically polyoxyethylene lauryl ether (EO: 2 To 8), polyoxyethylene myristyl ether (EO: 2 to 8) is preferred.

The solvent suitably used in the composition of the present invention is water, a low-boiling solvent, or a mixture thereof. As the low-boiling solvent, ethanol, isopropyl alcohol, isobutyl alcohol, acetone, or the like can be used. Although the composition of the present invention can be used in the form of being dissolved in an organic solvent, it is particularly preferable to use it in the form of being dispersed in water or a mixture of water and another solvent with a surfactant or modified silicone.

If necessary, the composition of the present invention may contain, in addition to the above main components, a polyhydric alcohol for imparting spreadability to the fiber and a fragrance for imparting a palatable fragrance.
