Description

Spray-type fiber treatment agent composition {FIBER PROCESSING AGENT COMPOSITION OF SPRAY TYPE}

The present invention relates to a spray-type fiber treatment agent composition.

As for the spray-type fiber treatment agent, various products are released and the market is expanding every year. As a function of a spray-type textile treatment agent, sterilization, deodorization, fragrance imparting, wrinkle removal, etc. are common, but a product that appeals to new functions such as imparting a refreshing feeling when worn is also appearing.

On the other hand, in the cosmetic field, many cosmetics (moisturizing cosmetics) that appeal to skin moisturizing are on the market (Patent Documents 1 to 3). Regarding moisturizing cosmetics, there is a technique for exhibiting a moisturizing effect while suppressing stickiness (Patent Documents 1 and 3).

Evaluation of fiber treatment composition

The fiber treatment agent composition was evaluated from the viewpoints of "provide to the textile product of a skin moisturizing function", "the treated textile product is sticky", and "spray property (ease of uniform spraying)".

1. Provision of skin moisturizing function to textile products

The moisture content of the skin was evaluated using the change in the moisture content as an index.

First, the "skin moisture content (initial)" of the evaluator was measured according to the following procedure. After washing the subject's forearm with a detergent and rinsing with running water, the subject's forearm was sufficiently absorbed with a towel. Then, after making it stable for 10 minutes in a constant temperature room (20 degreeC, 40%RH), the skin moisture content was measured with the coneometer (made by Integral Co., Ltd.).

Next, the "skin moisture content (after 6 hours)" of the evaluator after applying the textile product treated with the fiber treatment agent for 6 hours was measured according to the following procedure. A test cloth (10 cm x 10 cm) was prepared from a chemical fiber (38% polyester, 32% acrylic, 21% rayon, 9% polyurethane) heattech inner (manufactured by UNIQLO). Using the dispenser bottle (with a spray mechanism) of a commercial item (aroma rich fragrance mist. Lion Co., Ltd. product), 0.2 g of fiber treatment agent composition was sprayed uniformly to a test cloth, and it was made to dry for 30 minutes or more, and the treatment agent test cloth was prepared. The treatment agent test cloth was affixed to the forearm of the evaluator, and the skin moisture content of the affixed part was measured after the lapse of 6 hours. The measurement was performed using a coneometer (manufactured by Integral Co., Ltd.) after being stabilized for 10 minutes in a constant temperature room (20°C, 40% RH).

The above procedure was applied to the left and right arms of four evaluators. The measured value was applied to the following formula to calculate the skin moisture change rate (%).

Moisture change rate (%) = skin moisture content (after 6 hours) / skin moisture content (initial) x 100

The average value of the water change rate (%) of the four evaluators was applied to the following criterion, and it was set as evaluation of "the performance which provides a skin moisturizing function to a textile product". A result is shown in the "moisture retention" column of Table 1. (double-circle) and (circle) were made into pass.

<Judgment Criteria>

◎: average value of 130% or more

○: Average value is 110% or more and less than 130%

x: average value is less than 110%

2. Treated textile products are sticky

According to the procedure described in 1 above, a test cloth (10 cm × 10 cm. 1.4 g) was prepared. Using the dispenser bottle (with a spray mechanism) of a commercial item (aroma rich fragrance mist. Lion Co., Ltd. product), the fiber treatment composition was sprayed to the test cloth (spray amount: 15% o.w.f), and the treatment agent test cloth was prepared.

Before the sprayed fiber treatment composition dried, the treatment agent test cloth was touched by hand, and the sticky feeling felt by the evaluator when rubbed against the hand was sensory evaluated according to the following criteria. The average point (calculated to the first decimal place) of four evaluators was applied to the following criterion, and it was set as evaluation of "the stickiness of the processed textile product." A result is shown in the "stickiness" column of Table 1. (double-circle) and (circle) were made into pass.

<Evaluation criteria>

5 points: very sticky

4 points: quite sticky

3 points: there is stickiness

2 points|pieces: There is little stickiness

1 point: No stickiness

<Judgment Criteria>

◎: average score less than 2.0

○: average score of 2.0 or more but less than 3.0

3. Spray properties of fiber treatment composition

Using a commercial product (Aroma Rich Fragrance Mist. Lion Co., Ltd.) dispenser bottle (with a spray device), pull the fiber treatment composition to the center of the color broad (blue, 20 cm x 20 cm) once all the way to the end.引Ki) was sprayed. Spraying was performed at a distance of 20 cm from the color broad. The spray properties from the viewpoint of uniform spraying were evaluated according to the following criteria. The average point (computed to the first decimal place) of four evaluators was applied to the following criterion, and it was set as evaluation of "spray property of a fiber treatment agent composition." A result is shown in the "spray property" column of Table 1. (double-circle) and (circle) were made into pass.
