Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a divisor effect and is also excellent in preventing wrinkles, and is capable of removing wrinkles formed on clothing by simply applying it to the clothing and leaving it for a while. The present invention relates to a wrinkle-removal and anti-wrinkle agent composition.

[Prior art]

Clothes such as shirts, blouses, skirts, and pants often wrinkle during wear or storage, detracting from their aesthetic appearance.

In response to this, in the textile industry, new fiber materials, anti-wrinkle processing agents, new methods of knitting and weaving, etc. have been proposed and put into practical use. has not yet been found to be sufficiently effective. Incidentally, even if wrinkles are removed by ironing, there is a problem in that wrinkles will immediately appear due to wear or the like.

Recently, spray-type divisors that remove wrinkles by simply spraying them on wrinkled clothing have become commercially available, but at present they are not sufficiently effective on fine wrinkles on linen, etc. In order to improve the effect of this divisor, nonionic surfactants have been used to increase the permeability of certain substances into clothing, but nonionic surfactants with high permeability Many divisor compositions cause irritation to the eyes due to volatilization during spraying, and various divisor compositions have been proposed that do not cause any problems. For example, JP-A-1-168
No. 97 discloses a composition containing a surfactant and an aqueous alcohol solution that can be processed by the wool felt sedimentation method for 200 seconds or less, and JP-A-1-201597 discloses a composition containing an aqueous alcohol solution, a surfactant, a propellant, and an aqueous alcohol solution. , Japanese Patent Publication No. 1-2921
No. 85 discloses a composition containing a nonionic surfactant, silicone oil, a denatured alcohol aqueous solution, and a propellant.

In addition, as anti-wrinkle agents, compositions containing organopolysiloxanes having alkoxysilane/epoxy groups (JP-A-5
8-163782) and a composition containing a quaternary ammonium salt-modified organopolysiloxane/organopolysiloxane having a hydroxyl group bonded to silicon (Japanese Unexamined Patent Publication No. 58-70775).

[Problem to be solved by the invention]

The present invention can effectively remove fine wrinkles from cotton and linen, exhibits an excellent divisor effect even when left after being applied to clothing, makes wrinkles less likely to form, and also reduces eye irritation when sprayed. An object of the present invention is to provide a wrinkle-removing and anti-wrinkle agent composition for clothing that is mild.

[Means to solve the problem]

Focusing on the bending strength and bending recovery properties of clothing, divisor property means reducing bending strength and bending recovery property, and wrinkle resistance means improving bending strength and bending recovery property, and divisor and wrinkle resistance are completely opposite to each other. However, when a lower alcohol aqueous solution is combined with a specific modified silicone and a specific nonionic surfactant, when applied to clothing, the bending strength and bending recovery properties are reduced, and after drying, It was discovered that the bending strength and bending recovery before application were improved, and the divisor wrinkle resistance was dramatically improved, and that a specific nonionic surfactant caused mild irritation to the eyes. completed.
