[Effects of the Invention]

[0009] The present invention provides a textile detergent composition and a method for treating textile products that have good cleaning properties for textile products and make it easier to remove textile products from the washing machine after washing. [Modes for carrying out the invention]

[0010] The present invention has found that a composition containing components (a) and (b) in predetermined proportions has good cleaning properties for textile products and makes it easier to remove textile products from the washing machine after washing (for example, after spinning). Although the mechanism is not clear, it is presumed that the textile detergent composition of the present invention reduces the frictional force between wet fibers during washing while maintaining good cleaning properties by forming a hydrated solid of component (a) on the fiber surface. Here, it is presumed that the formation of the hydrated solid is promoted in the combined system of component (a) and component (b1). On the other hand, generally, the combined use of anionic surfactants and component (b2) tends to suppress the formation of the hydrated solid, but it is presumed that in the combined system of component (a) and component (b2), which are specific anionic surfactants, the formation of the hydrated solid of component (a) is maintained without impairment. As a result, entanglement of textile products is suppressed, and both good cleaning properties and ease of removal of laundry are achieved. The present invention provides a detergent composition for textiles and a method for treating textile products, which reduces friction between wet fibers during washing. This is expected to reduce washing damage and improve the finish of textile products by reducing wrinkles after washing.

[0123] (c) Component Propylene glycol • Butyl diglycol

[0124] <Examples and Comparative Examples> The liquid detergent compositions for textiles shown in Tables 1-6 were prepared by the following method and evaluated for the following items. The results are shown in Tables 1-6.

[0125] [Preparation of the composition] A 5cm long Teflon® stirrer piece was placed in a 200mL glass beaker and its mass was measured. Next, 20g of ion-exchanged water at 25°C, component (c), then component (b), then component (a) were added in that order, and the top of the beaker was sealed with Saran Wrap®. The beaker containing the contents was placed in a 60°C water bath set up on a magnetic stirrer, and stirred at 100 r / min for 30 minutes while the water temperature in the water bath was within the temperature range of 60±2°C. After that, the pH of the contents was adjusted to pH 7 using an alkaline agent (monoethanolamine) or an acidic agent (citric acid). The pH was measured using the pH measurement method described above. Next, the water in the water bath was replaced with 5°C tap water, and after the temperature of the composition in the beaker was cooled to 25°C, it was stirred for 10 minutes. Next, the Saran Wrap (registered trademark) was removed, deionized water was added so that the mass of the contents became 200g, and the mixture was stirred again at 100 r / min for 5 minutes to obtain the textile liquid detergent compositions described in Tables 1 to 6.

[0126] [Method for evaluating cleaning performance] (1) Preparation of a model sebum-stained fabric A fabric contaminated with model sebum was prepared by applying a model sebum artificial stain solution with the following composition to the fabric. The model sebum artificial stain solution was applied to the fabric by printing the artificial stain solution onto the fabric using a gravure roll coater. The process of preparing the model sebum artificial stain solution by applying it to the fabric was carried out using a gravure roll with a cell capacity of 58 cm². 3 / m 2 The coating was applied at a speed of 1.0 m / min, with a drying temperature of 100°C and a drying time of 1 min. Cotton 2003 (manufactured by Tanigashira Shoten) was used as the cloth. *Composition of model sebum artificial contamination solution: Lauric acid 0.4% by mass, myristic acid 3.1% by mass, pentadecanoic acid 2.3% by mass, palmitic acid 6.2% by mass, heptadecanoic acid 0.4% by mass, stearic acid 1.6% by mass, oleic acid 7.8% by mass, triolein 13.0% by mass, n-hexadecyl palmitate 2.2% by mass, squalene 6.5% by mass, egg white lecithin liquid crystal 1.9% by mass, Kanuma red clay 8.1% by mass, carbon black 0.01% by mass, water residue (total 100% by mass)

[0127] (2) Evaluation of cleaning power Five artificial sebum-stained fabric samples (6cm x 6cm) prepared as described above were washed for 10 minutes at 85 rpm using a turgotometer (Ueshima, MS-8212). In all cases, the washing conditions involved adding tap water (3.5°dH, 25°C) to achieve a concentration of 0.083% by mass of the textile liquid detergent composition described in Tables 1-6, and washing was performed at a water temperature of 25°C. After washing, the samples were rinsed with tap water (25°C) for 3 minutes and then dried. The cleaning rate (%) was measured using the method described below, and the average value of five samples was calculated. The results are shown in Tables 1-6. The reflectance at 550 nm of the original fabric before soiling and before and after cleaning was measured using a colorimeter (Nippon Denshoku Co., Ltd., Z-300A). In this evaluation, a higher cleaning rate is preferable as it indicates better cleaning performance. Cleaning rate (%) = 100 × [(Reflectance after cleaning - Reflectance before cleaning) / (Reflectance of the original fabric - Reflectance before cleaning)]

[0128] [Method for evaluating ease of removal] (1) Pretreatment of garments to be evaluated Approximately 4 kg of evaluation clothing was divided into approximately 2 kg portions using a nonionic surfactant (ethylene oxide adduct of lauryl alcohol (average number of added moles: 8)). Each portion was then washed five times consecutively in a Panasonic NA-F70PB11 automatic washing machine (4.5 g of nonionic surfactant used, standard course, 45 L of water, 25°C water temperature, 10 minutes washing time, 2 rinses). Afterwards, the garments were dried for one day under conditions of 25°C and 43% RH. The approximately 4kg of clothing used for evaluation consisted of five commercially available towels (Senshu towels, 100% cotton, 34cm x 86cm), four commercially available bath towels (Belle Maison Co., Ltd., 100% cotton), ten commercially available undershirts (Gunze YG undershirts (L), 100% cotton), five commercially available dress shirts (UNIQLO Big Silhouette Shirts (M), 100% cotton), five commercially available T-shirts (UNIQLO Crew Neck T-shirts, 100% cotton), and two commercially available pants (UNIQLO Chino Pants (XL), 100% cotton).

[0129] (2) Washing of the garments to be evaluated 27g of each of the compositions listed in Tables 1-6 was measured out, and 4kg of pre-treated garments were washed in a fully automatic washer-dryer (TOSHIBA AW-8D7) using 54L of tap water (25℃) and a total garment load of 4kg on a standard cycle (8 minutes wash, 1 rinse, 6 minutes spin).

[0130] (3) Evaluation of ease of removal After the washing process described in (2), the ease of removing clothes one by one from the washing machine drum into a laundry basket after spin-drying was evaluated. The evaluation was based on washing with the composition of Comparative Example 1-1, and six experienced individuals scored the garments according to the following criteria, and the average score of the six individuals was calculated. The scores from the six individuals were then tallied, and the average score was calculated. The table shows the values ​​rounded to two decimal places. The results are shown in Tables 1 to 6. In this evaluation, a higher average score indicates better ease of removal, which is preferable.

[0131] Evaluating how easy it is to remove textile products after spin-drying is not only an indicator of a finished product with less tangling and reduced damage to the textiles, but it is also a related indicator of how easy it is to hang and fold the clothes in subsequent washing processes, allowing us to understand the ease of use. -1...Compared to washing with the composition of Comparative Example 1-1, the clothes became tangled and were difficult to remove. 0…The ease of removal was equivalent to that when washing with the composition of Comparative Example 1-1. 1. Compared to washing with the composition of Comparative Example 1-1, the clothes were slightly less likely to tangle and easier to remove. 2. Compared to washing with the composition of Comparative Example 1-1, the clothes were less likely to tangle and were easier to remove.
