[0005] While textile product treatment compositions containing an anionic surfactant as a main ingredient exhibit excellent cleaning performance, they tend to cause wrinkles in the finished textile products after drying. In particular, when textile products are dried in a clothes dryer, wrinkles are formed significantly, and wrinkles must be removed by steam treatment or ironing after drying. In addition, since anionic surfactants have excellent foaming properties, foam control is also an important factor. For example, depending on the method of treating textile products, foam control may be required to prevent the foam formed during treatment from overflowing and excessive foam formation. In addition, if the amount of foam formed during treatment is reduced, the rinsing time and the amount of rinsing water can be reduced, so that the foaming property of the textile product treatment composition is required to be suppressed from the viewpoint of shortening treatment time and reducing environmental load. The present invention provides a textile product treatment composition which suppresses foaming of a treatment liquid used to treat a textile product and has excellent performance in suppressing wrinkles formed on the textile product during a drying process after the textile product is treated. [Means for solving the problem]

[0006] The present invention relates to a textile product treatment composition comprising the following components (a) and (b): Component (a): a sulfosuccinic acid ester or a salt thereof having a hydrocarbon group having 5 to 18 carbon atoms Component (b): one or more polymers selected from the following components (b1) and (b2): Component (b1): cationic polymer (b2) component: nonionic polymer

[0007] The present invention also relates to a method for treating a textile product, which comprises treating the textile product with a treatment liquid obtained by mixing the above-mentioned component (a), component (b) and water, and then drying the textile product. Effect of the Invention

The mechanism by which the textile product treatment composition of the present invention suppresses foaming during treatment and the mechanism by which the textile product is prevented from forming wrinkles when dried are not clear, but the following is presumed. First, it is presumed that the textile product treatment composition of the present invention suppresses foaming in an aqueous solution by forming a hydrated solid in the aqueous solution containing the treatment composition, and that the combined use of components (a) and (b) promotes the formation of a hydrated solid on the fiber surface, thereby reducing wrinkles formed on the textile product during the drying process. It is believed that this provides a textile product treatment composition and a textile product treatment method that simultaneously suppresses foaming of the treatment liquid used to treat textile products and reduces wrinkles that form on the textile products during the drying process after treatment of the textile products, particularly the drying process in a dryer.

In the present invention, when the hydrocarbon group is linked to the oxygen atom of the linking group (2), the carbon number of the hydrocarbon group of the component (b1) represents the carbon number of the hydrocarbon group bonded to the oxygen atom. When the hydrocarbon group is linked via a carbonyl group, an acyl group is bonded to the hydrocarbon group, and in this case, the carbon number of the hydrocarbon group of the component (b1) represents the carbon number of the acyl group. When the hydrocarbon group is linked via a carbonyloxy group and an oxycarbonyl group, the carbon numbers of the hydrocarbon group and the acyl group are included. When a 1,2-epoxyalkane is used to introduce a hydrocarbon group into a polysaccharide or polysaccharide polymer, the carbon number of the aliphatic hydrocarbon group bonded to the ether group generated from the epoxy group is represented.

[0113] (6) Evaluation of the defoaming properties of the treatment solution <How to prepare hard water> Hard water (Ca / Mg=8:2 (mass ratio)) was prepared by the following method. Calcium chloride dihydrate (FUJIFILM Wako Pure Chemical Industries, Ltd.) and magnesium chloride hexahydrate (FUJIFILM Wako Pure Chemical Industries, Ltd.) were weighed out in amounts equivalent to a German hardness of 150°DH so that the calcium ion / magnesium ion ratio (molar ratio) was 8 / 2, and the weighed compounds were dissolved in ion-exchanged water at 20°C to prepare a concentrated stock solution. This concentrated stock solution was diluted 100 times with ion-exchanged water and adjusted to 5°C to prepare hardness water.

[0114] <Method of measuring water hardness in Germany> The German hardness was measured by the following method. 〔reagent〕 0.01 mol / L EDTA·2Na solution: 0.01 mol / L aqueous solution of disodium ethylenediaminetetraacetate (titration solution, 0.01M EDTA-Na2, manufactured by Sigma-Aldrich) Universal BT indicator (product name: UniversalBT, manufactured by Dojindo Laboratories, Ltd.) Ammonia buffer solution for hardness measurement (67.5 g of ammonium chloride dissolved in 570 ml of 28 w / v% ammonia water, and then made up to 1000 ml with ion-exchanged water) [Method of measuring hardness] First, 20 mL of sample water was collected in a conical beaker using a whole pipette, and 2 mL of ammonia buffer solution for hardness measurement was added. Furthermore, 0.5 mL of Universal BT indicator was added, and it was confirmed that the solution after addition was reddish purple. While shaking the conical beaker well, 0.01 mol / L EDT·2Na solution was dropped from the burette, and the end point of the titration was when the sample water turned blue. The total hardness in the sample was calculated from the titration volume T (mL) of the EDTA·2Na solution using the following formula. Hardness (°DH)=(T×0.01×F×56.0774×100) / A T:0.01mol / L Titration amount of EDTA・2Na solution (mL) A: Sample volume (20 mL, volume of sample water) F: Factor of 0.01mol / L EDTA·2Na solution

[0115] <Evaluation of antifoaming properties> 50 mL of each hard water prepared by the above hard water preparation method was placed in a screw tube (No. 8), and 0.05 g of the textile product treatment composition in Table 1 was measured and dropped into it to prepare a treatment liquid. The screw tube was then capped and shaken at 300 rpm for 3 minutes with a shaker (STRONGSHAKER SR-2DW, manufactured by TAITEC), and the foam height (cm) 30 seconds after shaking was measured with a ruler. The defoaming performance was calculated by the following formula based on the foam height of Comparative Example 1. The calculated defoaming performance value is less than 1.0, and the lower the value, the better the defoaming treatment liquid is. A treatment liquid with excellent defoaming performance can also be said to have excellent rinsing properties. In addition, if the calculated defoaming performance value is more than 0, it can be said that the generated foam is appropriately maintained. Defoaming performance = (foam height (cm) of the treatment liquid of the Example or Comparative Example) / (foam height (cm) of the standard treatment liquid)
