Description

  The present invention relates to a fiber treatment agent for preventing adhesion of airborne particles and a spray product for preventing adhesion of airborne particles filled with the fiber treatment agent for preventing adhesion of airborne particles. More specifically, air useful for preventing the adhesion of pollen that causes allergies such as cedar pollen, tobacco smoke particles, and house dust, etc. to textiles such as clothing, futons, and sofas. The present invention relates to a fiber treatment agent for preventing adhesion of airborne particles and a spray product for preventing adhesion of airborne particles filled with the fiber treatment agent for preventing adhesion of airborne particles.

  It is said that the proportion of Japanese people suffering from so-called hay fever by cedar pollen is about 10-15% of the population, and hay fever is now considered to be a modern disease in the Japanese. . Hay fever develops unpleasant symptoms such as itchy eyes and nasal congestion that only people who suffer from it can see.

  As a countermeasure against such hay fever, a mask having fine stitches that do not easily penetrate pollen has been developed. However, since pollen adhering to clothing or handmade goods may re-scatter from the clothing into the air after entering the indoor space, hay fever may occur when the mask is removed indoors.

  Therefore, in order to prevent pollen from adhering to the fiber structure, a fiber structure to which a processing agent containing colloidal silica fine particles is attached has been proposed (for example, see Patent Document 1).

  However, the processing agent is used not by adhering to a product such as clothing obtained by processing a fiber material but by adhering to a fiber structure such as a shirt fabric, a skirt fabric, or a clothing fabric in advance. When a processing agent is attached to the fiber structure, it will surely provide a certain level of pollen adhesion prevention, but the fiber structure will be processed into products such as clothing. When it does, there exists a possibility that pollen adhesion prevention property may fall. Moreover, since the said processing agent is used together with another processing agent, there exists a fault that pollen adhesion prevention property is easy to be inhibited.

  Therefore, in recent years, when a patient suffering from hay fever goes out of the building to the outdoors, pollen drifting in the outdoor air can be easily prevented from adhering to clothing, etc., and pollen can adhere to clothing, etc. In this case, there is a long-awaited development of a fiber treatment agent for preventing pollen adhesion that can be easily removed and a spray product thereof.

A fiber treating agent was obtained by adding to 300 g of a mixed solvent in which water and a lower alcohol were mixed and stirring sufficiently.

  The solubility of the obtained fiber treating agent was visually observed and evaluated based on the following evaluation criteria. The results are shown in Table 2.

(Evaluation criteria for solubility of fiber treatment agents)
A: Slightly cloudy, but completely dispersed and transparent.
○: Although cloudy, it is almost completely dispersed. There is transparency.
Δ: White turbid but almost dispersed. Not transparent.

  Next, the obtained fiber treatment agent was filled in a 350 mL trigger type spray container to produce a spray product. Using this spray product, drying property and pollen adhesion preventing property were examined in the same manner as in Example 1. The results are shown in Table 2.

  From the results shown in Table 2, it can be seen that all of the fiber treatment agents obtained in Experimental Examples 12 to 29 have organopolysiloxane dissolved or dispersed therein. Moreover, it turns out that all the fiber processing agents in which surfactant is used are excellent in dispersibility.

  It can be seen that the test cloth using the fiber treatment agent obtained in each experimental example is superior in pollen adhesion preventing property as compared with the control test cloth not treated with the fiber treatment agent. Moreover, it turns out that the test cloth using the fiber treatment agent obtained in Experimental Examples 12 to 29 is excellent in drying property as compared with the control test cloth not treated with the fiber treatment agent.

Example 3

A test fabric was prepared by spraying the fiber treating agent from this sprayed product onto a cotton fabric having a size of 10 cm × 10 cm in an amount of 20 mL / m ² .

  On the other hand, as a control test cloth, a cotton cloth having a size not sprayed with a fiber treatment agent of 10 cm × 10 cm was prepared.

  Next, the test cloth and the control test cloth are put in a 15 L cylinder filled with tobacco smoke (secondary smoke), taken out after 5 minutes, and after 10 minutes, the test cloth and the control are given by 10 monitors. The scent of the test cloth was smelled and the odor intensity of the test cloth and the control test cloth was evaluated.

  As a result, 7 monitors evaluated that the cigarette smell was weak as a test cloth, and 1 monitor evaluated that the cigarette smell was weak as a control test cloth. Two monitors were evaluated.

  From the above results, it can be seen that treating the fiber with the fiber treating agent can prevent the smell of tobacco from adhering to the fiber.

  As a model of house dust, cotton linter was used, and 1 mg of cotton linter was uniformly adhered to the entire surface of the dried test cloth or the control test cloth.

  Next, a transparent resin container having a diameter of 9 cm is prepared, and the test cloth (control test cloth) is placed in the transparent resin container so that the surface on which the cotton linter is attached is located inside the transparent resin container. The test cloth (control test cloth) was fixed to the transparent resin container so that the opening was completely covered.

  The transparent resin container was lightly held with one hand, and the test cloth (control test cloth) surface was lightly repelled three times with the fingertip of the other hand to give vibration. Thereafter, the test cloth (control test cloth) was removed from the transparent resin container, the cotton linter in the transparent resin container was collected, and its weight was measured.

  As a result, the amount of cotton linter in the transparent resin container when using the test cloth was 0.8 mg, and the amount of cotton linter in the transparent resin container when using the control test cloth was 0.4 mg. From this, it can be seen that by treating the fiber with the fiber treating agent, it is possible to prevent the house dust from adhering to the fiber.
