Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a shine remover containing a specific silicone compound that is effective in removing shine from clothing.

[Conventional technology and its problems]

BACKGROUND ART When clothing such as suits, uniforms, boys' school uniforms, and girls' sailor suits are worn for a long period of time, shine often occurs in areas such as the elbows, knees, and hips, which significantly impairs the appearance of the clothing. Furthermore, repeated ironing of clothing can also cause shine on the surface.

The cause of shine is that due to long-term wear or ironing, the fine irregularities of the woven structure on the fiber surface become flat due to friction and compression, which increases the reflectance of light incident on the fiber surface. This is because the fiber surface appears shiny. This phenomenon is particularly noticeable in dark-colored clothing that has a low light reflectance, such as wool, wool/polyester blends, wool/
This is likely to occur in clothing made of materials such as nylon blends.

To prevent shine from occurring, it is somewhat effective to apply a pressure cloth and use a steam iron when ironing, but even with such operations, it is not possible to completely prevent shine from occurring. This is impossible, and at present there is nothing that can be done about the shine that occurs as a result of wearing clothing.

BACKGROUND ART In recent years, silicone has been increasingly attracting attention not only in the textile industry but also in all industrial fields as a processing agent that imparts unique textures and special effects to processed objects. In recent years, not only dimethylpolysiloxane, which has traditionally been the most common, but also various alkylpolysiloxanes and various modified silicones with various modified groups introduced into the alkyl group moieties have been developed. Amino-modified silicone with an amino group introduced into it, ether-modified silicone with one or both of ethylene oxide and propylene oxide groups introduced, hydrogen-modified silicone with the alkyl group replaced with hydrogen, and fluorine-modified silicone with an alkyl fluoride group introduced. There are modified silicones, epoxy-modified silicones into which epoxy groups have been introduced, and the like.

Among the various silicones mentioned above, amino-modified silicones are particularly excellent in adsorption to fibers and film-forming properties on fiber surfaces, and there is also a report that they have an anti-shiny effect (Japanese Unexamined Patent Publication No. 64-61576).

However, amino-modified silicones have too strong adsorption to fibers, so once they are adsorbed to fibers, they are difficult to remove with normal washing, and furthermore, the treated surface of clothing turns yellow when exposed to heat and light. Due to the problem of yellowing, it was not necessarily suitable as a base for preventing shine.

[Means to solve problems]

The present inventors have developed a method for removing shine from textiles that can easily remove shine generated on clothing at home, can be removed by home washing if necessary, and does not turn yellow on the treated fiber surface. As a result of intensive studies to find a composition, it was discovered that this object could be achieved by using an aminoether-modified silicone, and the present invention was completed.

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

Aminoether-modified silicone is a silicone represented by the following formula (A) in which the structural unit represented by the following formula (B) is added in m/
It contains a proportion in which (j!+m) is 0.005 or more, and contains a structural unit represented by the following formula (C) in a proportion in which n/(/!+n) is 0.005 or more. In addition, amino-modified silicone has the formula (B) in the silicone represented by the formula (A).
Contains the structural unit represented by m/(l+m) in a proportion of 0.005 or more.

The amount of the modified silicone blended in the shine-removing composition of the present invention is not particularly limited, but the total amount of the modified silicone relative to the weight of the clothing is 0.1 to 0.1 when applied by dipping, handy spray, or aerosol spraying. It is best to make it so that it weighs 5 weight. That is, in the case of dipping treatment, the total amount of modified silicone is 5 to 60%, and when used, it is diluted with water at 5% to 60%.
It may be diluted to ~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 aerosol, the total amount of modified silicone may be 0.2 to 5% in the liquid, and the composition may be sprayed onto clothing and then dried.

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

When spraying the composition of the invention in the form of a spray, the LP
All common propellants such as G, n-butane, fluorocarbon gas, carbon dioxide, dimethyl ether can be used.

When using aminoether-modified silicone and amine-modified silicone together, the blending ratio is aminoether-modified silicone/amino-modified silicone = 1/100 to 100.
/1, but the preferred blending ratio is aminoether-modified silicone/amino-modified silicone-1.
/10-10/1.

When a surfactant is added as a penetrant to the composition of the present invention, the modified silicone is quickly fixed on the fiber surface, resulting in an even shine removal effect. Nonionic surfactants are suitable as surfactants, and polyoxyethylene alkyl ethers, polyoxyethylene alkenyl ethers, polyoxyethylene alkylphenyl ethers, polyoxyethylene sorbitan fatty acid esters, etc. can be used, but they are difficult to penetrate into fibers. Polyoxyethylene alkyl ether with particularly good properties and more even shine removal effect, specifically polyoxyethylene lauryl ether (Il! 0:2-8), polyoxyethylene myristyl ether (80F 2-8). ) is preferred.

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

In addition to the above-mentioned main ingredients, the composition of the present invention may contain, if necessary,
A polyhydric alcohol to impart spreadability to the fibers and a fragrance to impart a pleasant aroma can be blended.
