Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an allergen-reduced bedding having a function of reducing allergens such as mites and pollen.

[0002]

2. Description of the Related Art Recently, atopic dermatitis, bronchial asthma,
Many allergic diseases such as allergic rhinitis are becoming a problem. The main cause is allergens (Der1, De) of house mites, especially dust mites that are often found in indoor dust.
This is because many allergens such as r2) and cedar pollen allergens (Crij1 and Crij2), which prevail in spring, are increasing in the living space. Especially the dust mite allergen, even if you eliminate the dust mite that causes it,
The dead insects supply substances with higher allergenicity to the living space, which does not provide a fundamental solution for allergic diseases caused by allergens. Further, Crij1 which is a cedar pollen allergen is a glycoprotein having a molecular weight of about 40 kDa, and Crij2 is a glycoprotein having a molecular weight of about 37 kDa, and when attached to the nasal mucous membrane or the like, it is recognized as an in vitro foreign substance and causes an inflammatory reaction. Therefore, in order to reduce the symptoms of allergic diseases or prevent new sensitization, it is necessary to completely remove the allergen from the living space or deactivate the allergen to inactivate it. In particular, bedding, mattresses, pillows, and other side fabrics, bedding, mattresses, pillows, beds, blankets, and other bedding typified by sheets, allergic symptoms appeared during prolonged contact and sleep. In this case, sleep is disturbed and the health is remarkably impaired. Therefore, the allergen reduction is most desired for patients with allergic diseases.

On the other hand, since the surface of the bedding is generally covered with a cloth made of fibers, allergens are likely to be accumulated and it is difficult to easily clean it with an electric vacuum cleaner or the like. Also, because they are so large that they cannot be wetted or do not fit into a domestic washing machine,
It was difficult to remove allergens by washing or required great effort. Therefore, JP-A-62-213
No. 707 of Japanese Patent No. 707 controls the size of the cloth of the bedding cover to a certain size, and Japanese Patent Publication No. 7-32735 also controls the method of fixing the cloth and batting so that mites do not pass into the futon. These technologies have been introduced and are actually on the market. However, the beddings of those special cloths and sewing methods cannot pass mites themselves, but the size of dead carcasses and feces of mites that are allergens is 1 / one of that of mites.
Since it is as small as 10 or less, it cannot be removed, and it is also impossible to control allergens which have been shattered into smaller pieces due to physical impact. Furthermore, it has no effect on the allergens in the dust that fall from inside and outside the bedding, not inside.

[0004]

Comparative Example 3 Polyethylene terephthalate (hereinafter PET) (intrinsic viscosity [η] = 0.65) was extruded with a screw type uniaxial extruder and molded into pellets. The pellets were spun in the same manner as in Example 1 (the filter of the pack in spinning was 270 mesh), stretched, washed with water, and dried to obtain a cloth. A bedding cover was produced using the obtained cloth.

[Evaluation of Allergen Reduction] Using the bedding covers obtained in Examples 1 to 4 and Comparative Examples 1 to 3 for 10 g each, a piece of evaluation cloth (33 cm × 30 cm) was prepared.
50 parts by weight of ethyl alcohol and 50 parts of purified water
1 ml of the prepared allergen in which 5 parts by weight of dust (allergen 2 mg / g) was dispersed was sprinkled on 1 part by weight to prepare a piece of cloth for evaluation. [Evaluation method (1)] After left at room temperature for 8 hours, the above-mentioned evaluation cloth piece was measured for allergenicity using an allergen determination kit "Daniscan" (manufactured by Asahi Breweries, Ltd.). The judgment was made according to the instruction manual of "Daniscan". The results are shown in Table 1.
Shown in. The criteria for tick scan are as follows: 1 ... No mite allergen contamination (test line T
= 0) 2 ... Slightly contaminated with mite allergen (T <C
Control line) 3 ... Contaminated with mite allergen (T = C) 4 ... Very contaminated (T> C)

[Evaluation method (2)] After 2 hours at room temperature, allergen components were extracted from the above-mentioned evaluation cloth according to a kit of "Mighty Checker" (manufactured by Shinto Fine Co., Ltd.), and the amount of allergen was measured. The results are shown in Table 1. Mighty checker criteria are as follows: ++ ... mite allergen level> 35 μg / m ² + ・ ・ ・ mite allergen level 10 μg / m ² ± ・ ・ ・ mite allergen level 5 μg / m ² − ・ ・ ・ mite allergen Level <1 μg / m ²

INDUSTRIAL APPLICABILITY In the allergen-reducing bedding of the present invention, the fibers themselves are subjected to the allergen-reducing treatment, so that patients with allergic diseases can live comfortably without causing allergic symptoms. Further, the bedding contaminated with the allergen does not require any post-treatment such as post-treatment with the reducing component. Further, even when the allergen reducing function is lowered, the reducing function is restored by a simple operation, so that the allergen reducing function can be exhibited semipermanently.
