[Method for Measuring Volume Swelling Ratio of Clay Mineral as Component (B)]

(39) The volume swelling ratio of the clay mineral as component (B), i.e. each of (b-1), (b-2) and (b-3) was calculated by the following method.

(40) 50 mL of an aqueous sodium lauryl benzene sulfonate solution with a concentration of 1000 mg/kg was put in a stoppered colorimetric tube with a capacity of 50 mL (IWAKI COLOR-TUBE50S). The temperature of the aqueous sodium lauryl benzene sulfonate solution was 25° C. Next, 0.5 g of the clay mineral was put in 10 parts into a glass tube in such a manner that the clay mineral was not attached on the wall surface of the glass tube. After the clay mineral was left standing within the temperature range of 25° C.±0.5 C° for 24 hours, the height of the deposited material was measured (L1h, mm). Separately, 0.5 g of the clay mineral alone was put in 10 parts into the heat-resistant glass tube with a capacity of 50 mL in such a manner that the clay mineral was not attached on the wall surface of the glass tube. After the clay mineral was left standing within the temperature range of 25° C.±0.5 C° for 24 hours, the height of the deposited material was measured (L2h, mm). Since the area of the inside bottom surface of the glass tube is constant, the volume swelling ratio can be calculated from the value of the height. That is, the value calculated from expression (1′) below is equal to the volume swelling ratio (%) from expression (1) above.
volume swelling ratio (%)=(L1h/L2h)×100  Expression (1′)

(43) Treatment agent compositions for textile products as shown in Tables 1 to 3 were prepared using the above formulation components and ion-exchanged water, and evaluation was performed for the following items. The results are shown in Tables 1 to 3.

(44) Specifically, the treatment agent compositions for textile products as shown in Table 1 were prepared in the following manner. A 5 cm-long Teflon (registered trademark) stirrer piece was put in a glass beaker with a capacity of 200 mL, and the mass of the beaker was measured. Next, 80 g of ion-exchanged water at 20° C., component (A) or component (A′), and component (B) were put in the beaker, and the beaker was sealed on the upper side with Saran Wrap (registered trademark).

(45) The beaker with the contents was placed in a water bath installed in a magnetic stirrer and kept at 60° C., and the contents were stirred at 100 r/min for 30 minutes within a temperature range of 60±2° C. in terms of a temperature of water in the water bath. Next, the water in the water bath was replaced by tap water at 5° C., and the beaker was cooled to 20° C. in terms of a temperature of the composition in the beaker. Next, Saran Wrap (registered trademark) was removed, and the pH at 20° C. of the treatment agent composition for textile products was adjusted to 7.5 using a 0.1 N aqueous sodium hydroxide solution or a 0.1 N aqueous hydrochloric acid solution. Next, ion-exchanged water was added so that the contents had a mass of 100 g, and stirring was performed again at 100 r/min for 30 minutes to obtain each of the treatment agent compositions for textile products as shown in Table 1. The treatment agent compositions for textile products in Tables 2 and 3 were similarly prepared. In Tables 1 to 3, the mass ratio of (A)/(B) is shown with component (A′) used in place of component (A).

This treatment was performed three times in total, and the towels were then left standing at 20° C. and 43% RH for 12 hours to be dried.

(58) (4) Evaluation of Softness

(59) Six persons skilled in evaluation of textile texture scored the softness of each of the dried cotton towels by the following criteria, and an average score among the six persons was calculated and rounded to two significant digits. Softness in each of Examples and Comparative Examples was evaluated in six grades with intervals of 0.5 between level 1 corresponding to score 0 and level 2 corresponding to score 3. Level 2 was superior to level 1 in terms of softness.

(60) −1: not softer than the cotton towel treated with the composition of level 1

(61) 0: as soft as the cotton towel treated with the composition of level 1

(62) 3: as soft as the cotton towel treated with the composition of level 2

(72) <Method for Evaluation of Cleaning Properties>

(73) (1) Preparation of Model Artificially Sebum-Stained Cloth

(74) A model artificially sebum-stained cloth was prepared by applying a model artificially sebum-staining liquid of the following composition to a cloth. The application of the model artificially sebum-staining liquid to the cloth was carried out by printing the artificially staining liquid on the cloth using a gravure roll coater. The process for preparing the model artificially sebum-staining cloth by applying the model artificially sebum-staining liquid to the cloth was carried out with a cell capacity of the gravure roll of 58 cm.sup.3/m.sup.2, a coating speed of 1.0 m/min, a drying temperature of 100° C. and a drying time of 1 minute. Cotton 2003 (manufactured by Tanigashira Shoten K.K.) was used as the cloth. *The composition of the model artificially sebum-staining liquid: lauric acid: 0.4 mass %, myristic acid: 3.1 mass %, pentadecanoic acid: 2.3 mass %, palmitic acid: 6.2 mass %, heptadecanoic acid: 0.4 mass %, stearic acid: 1.6 mass %, oleic acid: 7.8 mass %, trioleic acid: 13.0 mass %, n-hexadecyl palmitate: 2.2 mass %, squalene: 6.5 mass %, egg white lecithin liquid crystal substance: 1.9 mass %, Kanuma reddish soil: 8.1 mass %, carbon black: 0.01 mass %, and water: balance (total: 100 mass %).

(75) (2) Evaluation of Detergency

(76) Five model artificially sebum-stained cloths (6 cm×6 cm) prepared as described above were cleaned at 85 rpm for 10 minutes with a tergotometer (Ueshima, MS-8212). The cloths were each cleaned under the following conditions: city water (3.5° dH, 20° C.) was supplied so that the concentration of the treatment agent composition for textile products as shown in Table 1 was 0.033 mass %, and cleaning was performed at a water temperature of 20° C. After cleaning, the cloth was rinsed with city water (20° C.) for 3 minutes. Thereafter, the stained cloth after rinsing was subjected to dehydration treatment for 1 minute using a twin-tub washing machine, and then left standing at 20° C. and 43% RH for 12 hours to be dried. The degree of elimination of stains was visually observed. All the treatment agent compositions for textile products as shown in Table 1 were confirmed to have detergency because the model artificially sebum-stained cloth after cleaning was less stained than the cloth before cleaning. Further, the detergency was evaluated in the same manner as in evaluation of detergency in Table 1 except that cleaning liquids were adjusted so that the concentration of each of the treatment agent compositions for textile products as shown in Table 2 was 0.08 mass % and the concentration of each of the treatment agent compositions for textile products as shown in Table 3 was 0.11 mass %. All the treatment agent compositions for textile products as shown in Tables 2 and 3 were confirmed to have detergency because the model artificially sebum-stained cloth after cleaning was less stained than the cloth before cleaning.
