す。(Prior art) It is said that more than 90% of the causes of childhood asthma are mites. The cause of asthma is the mite itself (size 100
300300 μm), but the most influential ones are mite dust and carcasses (10-30 μm in size), which cause bronchial asthma. These can cause asthma unless removed. In particular, bedding such as futons, bed pads, blankets, stuffed toys, and carpets always have mites.If a child falls asleep on his / her face, rubs his face, or lays down, he / she will immediately be exposed to mites. Causes asthma attack by inhaling carcass.

からないといった欠点があった。Recently, in order to prevent mites occurring on beddings such as futons and blankets, beddings treated with an agent having a tick repellent effect have been developed. However, consumers are strongly reluctant to use such agents in bedding. This is especially true if the baby and child are symmetric. Experts recommend vacuuming futons and blankets to remove mites, dung and dead bodies. Vacuum cleaners for removing mites from bedding are also commercially available. Since this is a method of removing the causative substance, it has a considerable effect in preventing asthma attacks. However, there is a drawback that it is necessary to take a long time to vacuum, and it is not known whether the mites have been sufficiently removed.

があった。Therefore, a method has been proposed in which bedding such as a futon or a blanket is covered with a cover to prevent contact with ticks, dungs, and dead bodies (Japanese Patent Application Laid-Open No. 62-213707). This is a material obtained by subjecting a densely woven fabric to a high-density woven fabric in which a gap between fibers is reduced by subjecting the fabric to a crushing process such as a heat press, so as to have a function of preventing ticks. However, in these high-density fabrics, there is a correlation between the air permeability and the mite collecting effect, and the air permeability is 12 cm 3 / cm 2
If it is not less than s, a sufficient tick collecting effect cannot be obtained. The stuffiness due to sweating during sleep is suppressed as the air permeability and moisture absorption and absorption of the bedding are higher. In particular, in the summer months when sweating is severe, or in the case of children, higher air permeability is desired. or,
In the case of high-density woven fabric, it is densely woven and crushed,
When the surface of the fabric becomes slippery and is laid as sheets on the bedding, there has been a drawback that the bedding slips and falls during bedtime, or the bedding inside is rounded and the sleeping comfort is poor.

And a trapping efficiency of 90% or more for particles having a particle size of 1 μm or more.

選択できる。The “fabric” in the present invention includes, for example, knitted fabrics, woven fabrics, and nonwoven fabrics used for ordinary bedding. For use in bedding, it is desirable to use one that has excellent breathability, moisture absorption and water absorption, and does not accompany stuffiness while sleeping. When used as stuffed toys or carpet covers, it can be selected according to each application.

が、20〜120g/m2が好ましい。These fibers have a single yarn denier in the range of 0.02 to 2 denier; preferably 0.03 to 1 denier. 0.
Adhesion between single yarns of less than 02 denier is large, and sufficient air permeability cannot be obtained. On the other hand, if it exceeds 2 denier, the air permeability is improved, but sufficient collection efficiency, that is, anti-mite properties cannot be obtained. The size of mites, dung and dead bodies that are asthma causing substances is 10 to 30 μm. In order to prevent these particles from passing completely, the collection efficiency of particles having a particle size of 1 μm or more must be 90% or more. The basis weight of the web is not particularly limited, but is preferably 20 to 120 g / m 2 .

Range. That is, if the fiber filling ratio is less than 5%, the fiber gap becomes large, and the air permeability is good, but sufficient collection efficiency, that is, mite resistance cannot be obtained. If the fiber filling ratio exceeds 30%, sufficient air permeability cannot be obtained.

り、洗濯耐久性も良い。When the web is used as it is, when it is washed, it is feared that the surface is fluffed or deteriorated by the fir effect, so that sufficient washing durability cannot be obtained. In order to solve this, a mite-proof sheet is provided with a structure in which a web is interposed between at least one of a plurality of fabric layers. Lamination or adhesion between a plurality of fabric layers and a web is performed by a normal sewing method, a high frequency welder, a method of integrating with a sonic wave, or the like, and a hot melt resin is adhered to either the web surface or the fabric surface and heat-bonded. A method, a method of applying an adhesive to either the surface of the web or the surface of the fabric, and performing pressure bonding is used. In the case of ordinary sewing, it is conceivable that ticks, dungs, and dead bodies may come out of the needle holes. Therefore, after sewing, a thread whose needle holes are closed by heat treatment may be used. The method of integrating with a high-frequency welder or ultrasonic waves has a soft texture and a good washing durability.

If necessary, the web may be subjected to antibacterial processing, deodorizing processing, fragrance processing, mold prevention processing, or the like.

Webs of polyethylene terephthalate fibers having deniers of 0.02, 0.2, 1.5, 2.0 and 3.0 and a basis weight of 35 g / m 2 were obtained. On the other hand, 50 denier / 24 filament filaments of polyethylene terephthalate fiber were knitted using a circular knitting machine with a smooth knitting structure and a knitted fabric weight of 200 g / m 2 , and were scoured and dyed in a usual manner. A web was interposed between the two smooth knitted fabrics obtained as described above, and integrated with an ultrasonic sewing machine to evaluate the air permeability and the collection efficiency. Table 1 shows the results.
