にもアレルゲンが空中に浮遊することが明らかである。2. Description of the Related Art In recent years, allergic diseases such as asthma, allergic rhinitis and atopic dermatitis have been increasing. There are various causative allergens, but the importance of mites in particular has been pointed out. To prevent or treat the onset of allergic diseases, it is important to control mites in the home, that is, to remove mite antigens. In particular, bedding such as a futon contains many allergens such as mites, and it is clear that the allergen floats in the air when the futon is raised or lowered and during sleep.

気性が悪く、汗を全く吸わないという欠点があった。Conventionally, as a method of excluding allergens from futons, pillows and the like, there is a method of drying in the sun, but mites escape to the inner layer of futon cotton and a sufficient effect cannot be expected. In addition, extermination by mechanical washing of a futon will remove the allergen once by washing with water, but there is a risk that the allergen remaining on the machine will redeposit on the futon, and in some cases the allergen may not be sufficiently removed. If it is not managed properly, ticks will multiply in a few months. There is also a method of exterminating ticks with an insecticide, but the insecticide contains many drugs harmful to the human body and has a safety problem. further,
There is also a method of covering the futon with a film, but it has a drawback that it has poor breathability and does not absorb sweat at all.

There is a problem that it is difficult to fold when delivered. Also, average single fiber
When the fiber diameter d exceeds 5 μm, the low basis weight (8 g / m2

It is a spunbond nonwoven fabric. The spunbonded nonwoven fabric is melt-spun by the so-called spunbond method, that is, melt-spun and cooled from a spinneret, and pulled and thinned at a high speed by using a take-up means such as air sucker, and then the spreader is opened. By using the fibers to open the fibers and collecting and depositing them on the moving collecting surface, it is possible to easily obtain a nonwoven fabric having the single fiber fineness D made of the above-mentioned fibers.

Since it has poor mechanical properties such as resistance to bending and pulling, if an external force such as bending or pulling is applied to the ultrafine fiber non-woven fabric layer A during use, the fiber spacing of the ultrafine fiber non-woven fabric layer A will be easily opened and the allergen will not pass through. On the other hand, there is a problem that it cannot be prevented. On the other hand, when the fabric weight is high (more than 50 g / m 2 ), the thickness increases, the fiber spacing increases, and it retains allergens, which prevents sleep and causes skin disorders. I have a problem. Further, when the single fiber fineness D exceeds 10 denier, the mechanical properties similar to the above are deteriorated at a low basis weight (less than 10 g / m 2 ) and the fiber spacing becomes large,
When an external force such as bending or pulling is applied to the ultrafine fiber non-woven fabric layer A at the time of use, there is a problem that the fiber interval of the ultrafine fiber non-woven fabric layer A is likely to be opened and it is impossible to prevent passage of the allergen. (More than 2 ), there is a problem that the thickness becomes thicker, the texture becomes harder, the sleep is uncomfortable, and there is a rubbing sound, so that it is impossible to sleep well.

The ultrasonic projection device is formed by using an ultrasonic fusion device including an ultrasonic oscillator generally called a horn of z and a pattern roll having a convex projection in a dot shape or a strip shape on the circumference. The fibers that come into contact with the portions corresponding to are fused together. More specifically, the punctate fusion zone has a particular region and a particular arrangement relative to the total surface area of the three-layer laminate, although the individual punctate fusion zone need not necessarily be circular in shape. The ratio of the area of all punctate fusion parts to the total surface area of the three-layer laminate is 2 to 40%, preferably 4 to 25%, and the density of the same parts is 7 to 80 points / cm 2 , preferably 8 to 80.
A point / cm 2 is good. If the ratio of the area of all punctate fusion parts to the total surface area of the three-layer laminate is less than 2%, the ultrafine fiber non-woven fabric layer A and the long fiber non-woven fabric layer B are laminated by using an ultrasonic fusing device. The peel strength of the three-layer laminate obtained by integrally forming the heat-melting portion is not sufficiently improved, and when the area ratio exceeds 40%, the flexibility of the three-layer laminate obtained is increased. It is not preferable because it decreases. Further, if the density of the same part is less than 7 points / cm 2 , not only the adhesive strength of the obtained three-layer laminate, that is, peeling strength is uneven, but also the allergen passage inhibiting property is lowered, while the density of the same part is low. Is more than 80 points / cm 2 , the flexibility of the obtained three-layer laminate is lowered, which is not preferable.

The long-fiber non-woven fabric layer B is formed by the above, and the ultrafine-fiber non-woven fabric layer A can reduce the exposure amount of the allergen. In addition, the long fiber non-woven fabric layer B laminated on the ultrafine fiber non-woven fabric layer A
Thus, mechanical properties such as tensile strength and bending strength can be improved. In addition, since the ultrafine fiber nonwoven fabric layer A and the long fiber nonwoven fabric layers B on both sides of the ultrafine fiber nonwoven fabric layer A are laminated and integrated by the above-described thermal adhesion, the peeling strength between the layers is excellent. Particularly, in the case where the ultrafine fiber nonwoven fabric layer A and the long fiber nonwoven fabric layers B on both sides of this ultrafine fiber nonwoven fabric layer A are laminated and integrated by ultrasonic fusion, the peeling strength is remarkably achieved without impairing the flexibility. It will be expensive. Moreover, since the ultrafine fiber non-woven fabric layer A and the long fiber non-woven fabric layer B have the above-mentioned specific fiber diameter, fineness and basis weight, they satisfy the air permeability and the flexibility while maintaining the above mechanical properties and allergen blocking property. can do.

阻止性に若干劣るものの柔軟性に優れたものであった。The allergen-resistant bedding covers obtained in Examples 1 to 8 are excellent in peel resistance and flexibility as shown in Tables 1 to 3, and have good allergen passage-preventing properties. Met. In particular, the allergen-resistant bedding cover obtained in Example 6 was obtained by applying a coating on one side of the sheet of Example 1, and although it is slightly less flexible than Example 1, it is difficult to fluff and has good allergen content. It had a passage blocking property. The allergen-resistant bedding cover obtained in Example 7 was obtained by subjecting it to ultrasonic fusion treatment instead of the partial thermocompression treatment of Example 1, and was superior in flexibility and superior to Example 1. It had the ability to block passage of allergens. The allergen-resistant bedding cover obtained in Example 8 is one in which one of the polypropylene ultrafine fiber meltblown nonwoven fabric layer and the polypropylene long-fiber spunbonded nonwoven fabric layer of Example 1 has a smaller basis weight, and compared to Example 1, Although it was slightly inferior to allergen passage inhibition, it was excellent in flexibility.
