Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally uses futons for mattresses and rugs, and in particular, uses a fine cloth that is impermeable to ticks as the front and back sides of a futon, and has batting between the front and back sides. The present invention relates to an improvement of a mite-proof futon whose sewing edges are sewn with sewing threads.

[0002]

2. Description of the Related Art Conventionally, as measures against mites for futons, drugs are roughly classified to prevent mites from approaching with repellents, or to weaken and kill mites with insecticides that do not adversely affect the human body. Furthermore, there is also one that uses the radiant heat energy effect of the ceramic fine particles that have the far infrared ray radiating ability contained in the fiber.) And one that physically prevents mites from entering.

As a chemical agent, the cloth on the front and back sides of the futon which is treated with a repellent or an insecticide is used, or the futon cotton is treated with a chemical agent and is a tick-proof tick fiber having a tick-proof effect. Ordinarily, it was used, but on the side of the futon that directly touches the skin of the person, an ordinary cloth that is not treated with chemicals is used, and overwhelmingly many use mites as batting. .

As an example thereof, there is a pest control bag disclosed in Japanese Utility Model Publication No. 3-16874. This is composed of a fabric made of fibers containing ceramic particles having far-infrared radiating ability on one side of the bag body, and a fabric containing the insecticide, repellent insect repellent or both on the other side. When the bag is sun-dried, the mites whose escape to the one side is blocked by the repellent insect repellent are killed by the far infrared heat energy from the other side, or conversely the heat energy from the other side. The mites escaping from the one side are killed with an insecticide on one side to be exterminated.

[0005]

However, even if the mites are exterminated, the carcasses will become dust causing new allergic asthma and rhinitis, and it is essential to prevent the mites from physically entering the futon. is there. Therefore, since the body length of ticks is usually 400 μm to 500 μm, it is desirable to use a futon in which the front and back side cloths are stuffed so as not to make a gap larger than this. By the way, if the number of shots is about 250 or more and the stitches are squeezed, that is, the densely woven fabric is further compressed to squeeze the yarns constituting the fabric to reduce the gap between the yarns. For example, most mites cannot pass through the front and back ground fabrics.

[0006] If such a front and back side cloth is used, mites cannot penetrate into the futon through the front and back side cloth, but sewing is performed by joining the mating edges of the front and back side cloth of the futon using needles and threads. Another problem occurs that mites enter through the gap between the needle hole and the thread of the part. It is conceivable to make the needle as thin as possible for sewing, but needle breakage is likely to occur, and the sewing speed must be reduced, which reduces productivity. Further, a method of stopping the mating edges of the front and back side fabrics by adhesion can be considered, but the peeling strength cannot be sufficiently increased as compared with sewing, and it is not practically used at present.

The present invention has been made in view of the above-mentioned points, and the front and back side fabrics can be sufficiently secured without sacrificing productivity, while sufficiently securing the bonding strength of the joint sewing portion of the edges of the front and back side fabrics of the futon. It is an object of the present invention to provide an improved mite-preventing futon that prevents mites from invading through the gap between the needle hole and the thread, not only in the seams of the front and back ground edges.

[0008]

In order to achieve the above-mentioned object, the mite-proof futon according to claim 1 of the present invention comprises a batting sandwiched between fine front and back side fabrics which are impermeable to mites. In a mite-proof blanket made by sewing the mating edges of the above with sewing thread, the mating edges of the front and back sides are covered with at least half-folded hemmed fabric and sewn. Impregnated with insect repellent or insecticide.

According to the second aspect of the present invention, the fine front and back sides of the futon, which do not allow mites to pass through, have about 25 driving counts.
It is desirable to perform 0 or more blinding.

According to the third aspect of the present invention, it is preferable that the hem-processed fabric is folded in two at both side edges, and six layers of fabric are overlapped at the sewn portion.

According to a fourth aspect of the present invention, the sewing thread includes
It may be impregnated with a repellent insect repellent or insecticide.

[0012] As described in claim 5, mite-proof cotton can be used as the batting.

[0013]

In the mite-proof futon according to claim 1 configured as described above, since the fine front and back side fabric formed by further compressing the densely woven fabric is used,
Mites cannot enter the futon through the front and back sides of the futon. The front and back side fabrics are sewn at the mating edges with a batting between them, but the mating edges of the front and back side fabrics are covered with at least two folded hemmed fabrics. Since the mite is sewn from the sewn section, it cannot enter the straight line from the mating edge even if it tries to enter the duvet, and the entry path is long, and the mating edge is closely attached to each other by sewing the hemmed fabric. It is harder and harder to enter because it has been. Further, the hemmed fabric is
Since the repellent insect repellent or insecticide is impregnated, it is possible to completely prevent the invasion of mites through the gap between the needle hole and the thread in the seam of the edges of the front and back sides. The hemmed fabric does not have a bad influence on the human body since it hardly touches the human body during use even if it contains a repellent insect repellent or an insecticide. Therefore, it is possible to produce a human-friendly mite-proof futon that can sufficiently secure the bonding strength of the mating sewn portions of the front and back side edges of the futon and completely shut out mites while maintaining the conventional productivity. It will be possible.

According to a second aspect of the present invention, in the case of the mite-proof futon, since the fine front and back sides of the futon that do not allow mites to pass through are crushed when the number of hammered-in is about 250 or more, that is, the finely woven fabric. By further compressing and crushing the threads that make up the fabric to make the gap between the threads smaller, the mite has a body length of approximately 400 μm to 500 μm.
As it is, you cannot enter the futon through the front and back sides of the futon.

According to another aspect of the present invention, in the mite-proof futon, the hemmed fabric is folded in two on each side edge, and six layers of fabric are overlapped at the sewn portion. The degree of close contact is higher and the effect of closing the needle hole is higher.

In the mite-proof futon according to claim 4, since the sewing thread is impregnated with a repellent insect repellent or insecticide,
It has a synergistic effect with the above-mentioned hemmed fabric for preventing invasion of mites.

In the mite-proof futon according to the fifth aspect, since the batting is made of mite-proof cotton, the invasion of mites can be more reliably shut out.

[0018]

The anti-tick futon 1 has the front and back sides 11 and 12 thereof.
As the number of driven-in pieces is about 250 or more, a blunted cloth is used, and a batting 13 is sandwiched between the front and back side cloths 11 and 12, and the mating edges 11A and 12A are sewn and connected with a sewing thread 15. There is. As the fabric, natural fiber spinning of plants and animals such as cotton, hemp, wool and silk, synthetic fiber spinning of nylon, polyester, acrylic and vinylon,
A material woven from recycled fibers such as rayon and acetate is used. The densely woven fabric as described above is further compressed to squeeze the yarns forming the fabric to make the gap between the yarns smaller, and therefore the mite usually has a body length of almost Since it is 400 μm to 500 μm, it is made impossible to enter the futon 1 through the front and back side fabrics 11 and 12 of the futon.

As the batting 13, a tick-proof cotton obtained by treating natural fibers or synthetic fibers with a repellent insect repellent or insecticide is used. A hard cloth having an appropriate thickness is inserted into the batting 13 as a core according to the application of the mite-proof futon 1.

The mating edges 11A, 1 of the front and back side fabrics 11, 12
2A is covered with a hemmed cloth 16 in which both side edges are folded inward, and then a sewing thread 15 is formed by a two-needle sewing machine.
Sewn at 15. In the sewn portion 14, since the six layers of fabrics are overlapped with each other, the degree of close contact between the fabrics is high and the effect of closing the needle hole is high at the same time.

As the hemmed fabric 16, the same fabric as the front and back side fabrics 11 and 12 as described above is sufficiently impregnated with a repellent insect repellent or insecticide. The sewing thread 15 is also sufficiently impregnated with the repellent insect repellent or insecticide. Therefore, the sewing thread 15 and the hemmed cloth 16 sufficiently containing the repellent insect repellent and the insecticide completely prevent the invasion of mites from the gap between the needle hole and the sewing thread 15 as well as the gap between the cloths. You can As described above, since the sewn portion 14 is also protected against ticks, it is not necessary to use a particularly thin needle, and therefore, it is not necessary to reduce the sewing speed, and sufficient bonding strength is maintained. Since the six layers of fabric are overlapped with each other as described above, the degree of close contact between the fabrics is high, and at the same time, the effect of closing the needle hole is high, and in combination with the use of the repellent insect repellent and insecticide, Measures to prevent tick invasion are perfect.

As repellent insect repellents, toluamide compounds and nicotine compounds are used, and as insecticides,
Pyrethroid compounds and organic phosphorus compounds are used, but they can be used in combination.

When the mite-proof duvet 1 having the above-mentioned structure is manufactured as a comforter, it is manufactured according to the process sequence shown in FIG. That is, the mite-proof quilt 1 selects the raw fabrics of the front and back side fabrics 11 and 12 in the first system and appropriately cuts them for single or double, and the mating edges 11A and 12A are combined with the mite-proof hem-treated fabric 16 and fabric. Side-sewing is performed using the mite sewing thread 15, and the mite-preventing raw cotton of the batting 13 is selected in the second system in parallel with the above-mentioned first system, and the cotton is produced by the confluence system of both parallel systems described above. 1 batting on the bag after the side sewing

EFFECTS OF THE INVENTION As is clear from the above description, the following effects can be obtained by the mite-proof futon according to claim 1 of the present invention.

(1) Since fine front and back side fabrics formed by further compressing the finely woven fabric are used, mites entering the futon through the front and back side fabrics Intrusion can be prevented.

(2) Also, by inserting a batting between the front and back sides,
Even if mites try to enter the duvet from this sewing part, the straight part is sewn from the mating edge because the sewing edge is sewn with sewing thread and covered with at least half-folded hemmed fabric. It is not possible to enter, the entry path is long, and it is even more difficult to enter because the mating edges are sewn together by the sewing of the hemmed fabric.

(3) Further, since the hemmed fabric contains a sufficient amount of repellent insect repellent or insecticide, the hemmed fabric is sewn from the gap between the needle hole and the thread in the joint sewing portion of the edges of the front and back sides. Invasion of ticks can be completely prevented. The hemmed fabric does not have a bad influence on the human body since it hardly touches the human body during use even if it contains a repellent insect repellent or an insecticide.

(4) Since a thin needle is not used and a special additional process that takes time is not required, the bonding strength of the joint sewing portion of the edges of the front and back sides of the futon can be secured as before and the mites can be completely removed. It will be possible to manufacture shut-out human-friendly anti-tick futons while maintaining almost the same productivity as before.

(5) In the mite-proof futon according to the second aspect, the fine front and back sides of the futon, which do not allow mites to pass, are woven finely because they are crushed when the number of hammers is about 250 or more. By further compressing the cloth and crushing the threads that make up the cloth to make the gap between the threads smaller, the mite has a body length of approximately 400 μm to 500 μm.
Since it is m, it can prevent entering the futon through the front and back sides of the futon.

(6) In the mite-proof futon according to claim 3, since the hemmed fabric is folded in two at each of both side edges and six layers of fabric are overlapped at the sewn portion, the front and back fabrics are It is possible to further enhance the degree of close contact with the edges of the needle and to enhance the effect of closing the needle hole.

(7) In the mite prevention futon according to claim 4, since the sewing thread contains a sufficient amount of repellent insect repellent or insecticide, it is necessary to prevent the invasion of mites together with the hemmed fabric. There will be a synergistic effect.

(8) In the mite-proof futon according to claim 5, since the batting is mite-proof cotton, the invasion of mites can be shut out more completely.
