A rotary processing method refers to a processing method in which textile products that are not fixed to a rotating machine are rotated around a rotating shaft together with the processing liquid. The rotary processing method can be carried out using a rotary washing machine. Specifically, rotary washing machines include drum-type washing machines, pulsator-type washing machines, and agitator-type washing machines. Commercially available rotary washing machines for household use can be used. Drum-type washing machines have become rapidly popular in recent years because they can reduce the amount of water used in one wash cycle. Drum-type washing machines, in particular, can reduce the amount of water used during washing. [Examples]

The sebum components were then spread onto the textile product in a constant temperature bath (60°C, 1 HR), and after standing overnight in a room at 20°C / 65%RH, the samples were used for the treatment test. A total of 8 sheets were used per bath during the treatment test.

Preparation of textile products for bath ratio adjustment Two types of textile products (cotton knit fabric (unspun cotton, 100% cotton, Tanigashira Shoten) and polyester jersey (Tanigashira Shoten), each cut into 6cm x 6cm squares) were processed using a bath ratio of 20, with 23 pieces of cotton knit fabric and 10 pieces of polyester jersey fabric being used.

[0113] <Processing methods for textile products> <Processing conditions> The fibers were treated using a terg-O-tometer. 600 mL of the aforementioned textile treatment solution was placed in a 1-liter stainless steel cylindrical container (for Terg-O-Tometer), and eight evaluation textile products, eight polyester faille fabrics free of model sebum stains (criterion 3 for odor evaluation), and 33 textile products with the aforementioned bath ratio adjustment were placed inside. Each treatment was then carried out under the following conditions. • Processing: Textile products were processed under the following conditions: rotation speed of 100 r / m, 10 min, and bath ratio of 20. • Dehydration: All textile products processed under the above conditions were removed from the beaker and placed in the spin-drying tub of a twin-tub washing machine (Hitachi, Ltd., PS-H45L) and dehydrated for 1 minute. • Rinsing: Fresh water (Wakayama City water, 20°C) was added to the aforementioned stainless steel beaker, and the textile products were rinsed under the conditions of a rotation speed of 100 r / m, 10 min, and a bath ratio of 20. • Dehydration: All the textile products rinsed in the above rinse were removed from the beaker and placed in the spin-drying tub of a twin-tub washing machine (Hitachi, Ltd., PS-H45L) and dehydrated for 1 minute. Eight textile products were removed immediately after spin-drying, stacked, and placed in a disposable petri dish with a lid. The odor of each product was then evaluated immediately after washing. Furthermore, visual inspection of the evaluation textile products after dehydration revealed that while the cleaning was successful, some dirt remained.

[0114] <Method for evaluating deodorizing effect> The odor level derived from model sebum stains emanating from textile products treated with the textile treatment solution of Example 1 was assigned an evaluation score of 2 (criterion 1), the odor level derived from model sebum stains emanating from textile products treated with the textile treatment solution of Comparative Example 1 was assigned an evaluation score of 1 (criterion 2), and the odor level derived from model sebum stains emanating from textile products without model sebum stains emanating was assigned an evaluation score of 6 (criterion 3). The relative odor level to each criterion was evaluated in increments of 0.5 points. The odor evaluation was performed by three evaluators skilled in sensory evaluation of odors, and the average score was calculated. The results are shown in Table 4. A higher evaluation score indicates superior deodorizing effect.

[0121] [Table 5]

[0122] [Table 6]

[0123] When evaluating the deodorizing effect using the textile product treatment solutions of Examples 1 to 13, according to the textile product treatment method and deodorizing effect evaluation method in the above-mentioned examples, the following can be considered. Since the amount of composition example 1 used to prepare treatment solution example 1 is greater than that used to prepare example 1, treatment solution example 1 is considered to have a superior deodorizing effect than example 1. Also, when preparing treatment solutions examples 2 to 4, the amount of composition example 4 used is greater for treatment solution example 3 than for treatment solution example 2, and then for treatment solution example 4, so the deodorizing effect of treatment solutions examples 2 to 4 is considered to be better for treatment solution example 3 than for treatment solution example 2, and then for treatment solution example 4. Also, since the amount of composition example 4 used to prepare treatment solution example 2 is less than the amount used to prepare example 4, treatment solution example 2 is considered to have a slightly inferior deodorizing effect than example 4, but the deodorizing effect is still satisfactory. Also, since the amount of composition example 4 used to prepare treatment solutions examples 3 and 4 is greater than the amount used to prepare example 4, treatment solutions examples 3 and 4 are considered to have a superior deodorizing effect than example 4. Furthermore, since the amount of composition example 5 used to prepare treatment solution example 5 is greater than the amount used to prepare example 5, treatment solution example 5 is considered to have a superior deodorizing effect compared to example 5. Also, since the amount of composition example 12 used to prepare treatment solution example 6 is greater than the amount used to prepare example 12, treatment solution example 6 is considered to have a superior deodorizing effect compared to example 12. Furthermore, since treatment solution example 7 contains component (e) in addition to example 4, treatment solution example 7 is considered to have a superior deodorizing effect compared to example 4. Treatment solution example 8 has a slightly inferior deodorizing effect compared to example 4, but the deodorizing effect is considered satisfactory. Furthermore, since the (b) / (a) ratio of treatment solutions examples 9 and 10 falls outside the most preferable range, the deodorizing effect is slightly inferior to example 4, but the deodorizing effect is considered satisfactory. Furthermore, since the (c) / {(a)+(b)} ratio of treatment solution example 11 falls outside the most preferable range, the deodorizing effect is inferior to example 1, but a sufficient deodorizing effect is considered to be obtained. In example 12 of the treatment solution, the (b) / (a) ratio and (c) / {(a)+(b)} ratio fall outside the most preferable range, resulting in a slightly inferior deodorizing effect compared to Example 4 and Examples 10 and 11, although the deodorizing effect is considered satisfactory. In example 13 of the treatment solution, the deodorizing effect is considered to be equivalent to that of Example 4.
