Test Category 2 (Emulsifying)

Each treatment agent prepared for test category 1 was diluted with ion-exchange water to prepare a dilution (emulsion) with a non-volatile component concentration of 1.0%. This diluent was used to evaluate emulsification properties as stability.

The light transmittance (%) of the diluted solution of each treatment agent at a wavelength of 750 nm was measured under conditions of 20° C. and 60% RH. As a measuring device, a spectrophotometer UV-1800 SPECTROPHOTOMETER manufactured by Shimadzu Corporation was used. The emulsifying properties of the diluent were evaluated based on the following criteria. The results are shown in the "Emulsifying Properties" column of Table 1.

・Evaluation criteria for emulsification properties ◎(Good): No separation, light transmittance above 50% 〇 (Acceptable): No separation, light transmittance is more than 30% and less than 50% × (poor): There is separation

Test Category 3 (Softness)

The evaluation was conducted using 7 denier polyester synthetic fiber cotton with a cutting length of 32 mm, which is commonly used for padding, quilts, etc. In order to avoid being affected by lubricants used in the production of polyester synthetic fibers, the washing operation was first carried out with warm water at 40°C, and then dried at 80°C for 2 hours before evaluation.

The treatment agent prepared in each example of test category 1 was diluted to prepare a diluted liquid in the form of an emulsion with an active ingredient concentration of 12.5%. Spray 2.4g of lotion evenly on 100g of polyester synthetic fiber cotton. Then, heat treatment (drying treatment) was performed at 180°C for 10 minutes to prepare a sample sponge for evaluation. That is, 0.3g of treatment agent is attached to 100g of cotton.

・Evaluation of softness Five examiners familiar with fiber texture evaluation rated the softness of the dried sample sponge using the following criteria, and then the average score of the five examiners was rounded to two significant figures. The softness was evaluated based on the calculated average score using the following criteria. The results are shown in the "flexibility" column of Table 1.

1 point: The softness is roughly the same as that of polyester synthetic fiber without treatment agent. 2 points: The softness felt is greater than that of polyester synthetic fiber without treatment agent. 3 points: The softness felt is much greater than that of polyester synthetic fiber without treatment agent.

◎(Good): The average score of 5 people is 2.5 points or more 〇 (Acceptable): The average score of 5 people is more than 2.0 points and less than 2.5 points × (Poor): The average score of 5 people did not reach 2.0 points

Test category 4 (antistatic properties)

Humidity adjustment was carried out for 24 hours in a constant temperature room at 20° C. and 45% relative humidity, with 5 g of sample sponges to which each treatment agent prepared in test category 3 was attached. Then, the resistance of the polyester synthetic fiber was measured using a known resistance measuring device, and evaluated based on the following evaluation criteria. The results are shown in the "antistatic property" column of Table 1.

・Evaluation criteria for antistatic properties ◎ (Good): Surface resistance is less than 1.0×10 ¹¹ Ω 〇 (Fair): Surface resistance is 1.0×10 ¹¹ Ω or more and less than 1.0×10 ¹² Ω × (Bad): Surface resistance 1.0×10 ¹² Ω or more

Test Category 5 (Fluffiness)

The bulkiness is evaluated by measuring the compression elastic recovery rate. The compression elastic recovery rate is measured by a test method similar to JIS L 2001.

40 g of sample cotton with each treatment agent prepared in Test Category 3 attached was passed through a roller carding machine to prepare a card net with a treatment agent of 30 cm × 100 cm attached. Cut the carded net into 15cm×15cm fabrics and make 4 pieces. Overlap 4 pieces of fabric to form a cuboid, with the fiber directions perpendicular to each other.

After letting it stand for 30 minutes at 20°C and 40% RH, a 15cm×15cm metal plate (135g) was placed on the cube, and the height (h1) of the cube after 1 minute was recorded in units of 0.1cm. Then put a 1125g weight on the metal plate, record the height (h2) after leaving it for 24 hours, and then remove the weight. Record the height of the cube (h3) 1 minute after removing the weight.

Calculate the recovery rate by the following formula. Recovery rate (%) = 100×(h3-h2)/(h1-h2)

The higher the recovery rate, the better the fluffiness of the sample cotton.

◎(Good): Recovery rate (%) 80% or more 〇 (Acceptable): Recovery rate (%) is more than 50% and less than 80% × (Bad): Recovery rate (%) does not reach 50%
