Description

[Technical Field]

[0001] The present invention relates to a textile product treatment agent composition and a method for treating textile products. [Background technology]

[0002] Conventionally, anionic surfactants such as alkylbenzene sulfonates, alkyl sulfates, polyoxyethylene alkyl ether sulfates, internal olefin sulfonates, and sulfosuccinates have been used as cleaning agents for household and industrial use.

[0003] Patent Document 1 discloses a detergent composition comprising a predetermined (A) anionic surfactant, (B) at least one amphoteric surfactant, and (C) at least one nonionic surfactant. Patent Document 2 discloses a liquid detergent composition for textile products, which contains predetermined amounts of (A) an internal olefin sulfonate, (B) a predetermined organic solvent, (C) a predetermined water-soluble polyhydric alcohol, and water, and the mass ratio (B) / (C) of the content of component (B) to the content of component (C) is 0.1 or more and 10 or less.

[0004] [Patent Document 1] Japanese Patent Publication No. 2015-151360 [Patent Document 2] Japanese Patent Publication No. 2021-088703 [Patent Document 3] Japanese Patent Publication No. 2020-105422 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] While textile treatment compositions primarily composed of anionic surfactants exhibit excellent cleaning performance, they tend to cause wrinkles in textile products after drying. In particular, wrinkle formation is significant when textile products are dried in a clothes dryer, requiring post-drying treatment with steam or ironing to remove wrinkles. Furthermore, since anionic surfactants have excellent foaming properties, foam control is also an important factor. For example, depending on the processing method for textile products, it may be necessary to control the foam to prevent it from overflowing or to prevent excessive foam formation during processing. Also, reducing the amount of foam formed during processing allows for a reduction in rinsing time and the amount of rinse water used, so suppressing the foaming properties of textile product processing agent compositions is desirable from the perspective of shortening processing time and reducing environmental impact. The present invention provides a textile product treatment agent composition that suppresses foaming of the treatment solution used to treat textile products and exhibits excellent wrinkle suppression performance in the drying process after treatment of textile products. [Means for solving the problem]

[0006] The present invention relates to a textile product treatment agent composition containing the following components (a) and (b). (a) Components: Sulfosuccinate esters or salts thereof having hydrocarbon groups with 5 to 18 carbon atoms. (b) Components: One or more polymers selected from the following components (b1) and (b2). (b1) Ingredients: Cationic polymer (b2) Ingredients: Nonionic polymer

[0007] Furthermore, the present invention relates to a method for processing textile products, comprising processing the textile products with a processing solution obtained by mixing component (a), component (b), and water, and then drying the textile products. [Effects of the Invention]

[0008] According to the present invention, a textile product treatment agent composition is provided that suppresses foaming of the treatment solution used to treat textile products and exhibits excellent wrinkle suppression performance in the drying process after treating the textile products. [Modes for carrying out the invention]

[0009] The present invention has found that by using components (a) and (b) described above, it is possible to obtain a textile product treatment agent composition and a method for treating textile products that suppress foaming during textile product treatment and further reduce wrinkles formed on textile products during the drying process, particularly the drying process using a dryer, in a wet state. Although the mechanisms by which the textile product treatment composition of the present invention suppresses foaming during treatment and suppresses wrinkle formation during drying of textile products are not yet clear, the following can be inferred. First, it is presumed that the textile product treatment agent composition of the present invention suppresses foaming in the aqueous solution by having component (a) form a hydrated solid in the aqueous solution containing the treatment agent composition. Here, it is presumed that in the combined system of component (a) and component (b), the formation of a hydrated solid on the fiber surface is promoted, resulting in a reduction of wrinkles formed on the textile product during the drying process. This is believed to provide a textile product treatment agent composition and a textile product treatment method that achieve both suppression of foaming in the treatment solution used to process textile products and reduction of wrinkles formed on textile products during the drying process after treatment, particularly in the drying process in a dryer. Furthermore, the textile product cleaning agent composition and the method for treating textile products of the present invention are not limited to the mechanism of action described above.

Component (b1) may be a polysaccharide polymer in which a cationic group is directly or via a linking group bonded to a group obtained by removing a hydrogen atom from the hydroxyl group of a polysaccharide or a derivative thereof, which is a precursor compound of component (b1). Note that the above phrase "a cationic group is directly or via a linking group bonded to a group obtained by removing a hydrogen atom from the hydroxyl group of a polysaccharide or a derivative thereof" does not include bonding modes in which a cationic atom of the cationic group, such as a nitrogen cation, is directly covalently bonded to the oxygen atom of the hydroxyl group of the polysaccharide or a derivative thereof.

[0038] From the viewpoint of defoaming and suppression of wrinkle formation during drying, it is preferable to select the content of cationic groups in component (b1). The content of cationic groups in the polysaccharide polymer having cationic groups, which is component (b1), is calculated by replacing the cationic groups with nitrogen atoms.

One linking group (2) may be one of the aforementioned linking groups, or it may be a combination of multiple types. Furthermore, the polysaccharide polymer may contain one type of linking group, or multiple types. In the present invention, when the hydrocarbon group is linked to the oxygen atom of the linking group (2), the number of carbon atoms in the hydrocarbon group of component (b1) represents the number of carbon atoms in the hydrocarbon group bonded to the oxygen atom. When the hydrocarbon group is linked via a carbonyl group, it becomes a structure with an acyl group bonded, and in this case, the number of carbon atoms in the hydrocarbon group of component (b1) represents the number of carbon atoms in the acyl group. Similarly, when linked via a carbonyloxy group and an oxycarbonyl group, the number of carbon atoms in those groups is also included. When introducing a hydrocarbon group into a polysaccharide or polysaccharide polymer, if 1,2-epoxyalkane is used, it represents the number of carbon atoms in the aliphatic hydrocarbon group bonded to the ether group generated from the epoxy group. The epoxy group portion becomes linking group (2). For example, when introducing a hydrocarbon group into a polysaccharide or polysaccharide polymer using 1,2-epoxytetradecane, the number of carbon atoms in the hydrocarbon group is 12. In other words, an oxyethylene group, which is a linking group (1), is bonded to the hydroxyl group of a polysaccharide or polysaccharide polymer, and a C12 alkyl group (dodecyl group) is bonded via this linking group. The same applies when alkylglycidyl ethers are used.

[0112] (5) Evaluation of wrinkle suppression ability The wrinkle condition of T-shirts that had been washed, rinsed, and dried using the method described in (4) above was scored by six experts in textile texture evaluation according to the following criteria, and the average score of the six was calculated. The results are shown in Table 1. The table shows values ​​rounded to one decimal place. In this evaluation, an average score of 1 or higher is preferable, and a higher numerical value is preferable. -1…The T-shirts treated with the composition of Comparative Example 1 had more wrinkles. 0…The T-shirt treated with the composition of Comparative Example 1 achieved a wrinkled state equivalent to that of the T-shirt treated with the composition of Comparative Example 1. 1.

Compared to T-shirts treated with the composition of Comparative Example 1, the finished product had significantly fewer wrinkles.

[0113] (6) Evaluation of the defoaming properties of the treatment solution <Method for preparing hard water> Hard water (Ca / Mg = 8:2 (mass ratio)) was prepared using the following method. A concentrated stock solution was prepared by weighing calcium chloride dihydrate (Fujifilm Wako Pure Chemical Industries, Ltd.) and magnesium chloride hexahydrate (Fujifilm Wako Pure Chemical Industries, Ltd.) in amounts equivalent to a German hardness of 150°DH, such that the calcium ion / magnesium ion ratio (molar ratio) was 8 / 2. The weighed compounds were dissolved in deionized water at 20°C to prepare a concentrated stock solution. This concentrated stock solution was diluted 100 times with deionized water and the temperature was adjusted to 5°C to obtain hard water.

[0114] <Method for measuring water hardness in Germany> German hardness was measured using the following method. 〔reagent〕 • 0.01 mol / L EDTA-2Na solution: A 0.01 mol / L aqueous solution of disodium ethylenediaminetetraacetate (titration solution, 0.01MEDTA-Na2, manufactured by Sigma-Aldrich). • Universal BT Indicator (Product name: UniversalBT, manufactured by Dojin Chemical Laboratories Co., Ltd.) • Ammonia buffer solution for hardness measurement (a solution made by dissolving 67.5g of ammonium chloride in 570ml of 28w / v% ammonia water and diluting the total volume to 1000ml with deionized water). [Method for measuring hardness] First, 20 mL of water, to be used as the sample, was collected in a conical beaker using a volumetric pipette, and 2 mL of ammonia buffer 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, a 0.01 mol / EDTA·2Na solution was added dropwise from the burette, and the titration was terminated when the water sample turned blue. The total hardness in the sample was calculated from the titration volume T (mL) of 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 water used as the sample) F: Factor of 0.01 mol / L EDTA-2Na solution

[0115] <Evaluation of defoaming properties> 50 mL of each hard water prepared using the above method was placed in a screw-top tube (No. 8), and 0.05 g of the textile product treatment agent composition shown in Table 1 was weighed out and added dropwise to prepare the treatment solution. Then, the screw-top tube was capped and shaken at 300 rpm for 3 minutes using 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 using the following formula, based on the foam height of Comparative Example 1. A calculated defoaming performance value of less than 1.0 indicates that the treatment solution has superior defoaming properties. A treatment solution with superior defoaming properties can also be said to have superior rinsing properties. Furthermore, if the calculated defoaming performance value is greater than 0, it can be said that the foam generated is maintained at an appropriate level. Defoaming performance = (Foam height of the treatment solution in the example or comparative example (cm)) / (Foam height of the standard treatment solution (cm))
