Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of futon as bedding.

[0002]

2. Description of the Related Art Conventionally used futon cotton (heat insulating material) for bedding includes cotton, feathers, wool, genuine cotton, synthetic fiber cotton, etc., which may be used alone or in a mixture of two or more kinds (mixed spinning etc.). Used by etc. Fibers called flame-retardant fibers may also be mixed and used in these heat insulating materials,
It has also been a while since a heat insulating material that has been subjected to flame retardant treatment with chemicals has been used.

[0003]

[Problems to be Solved by the Invention] Temperature and humidity in a bed are the most important conditions for comfortable sleep. In the area where the temperature and humidity inside the bed during sleep are comfortable, the temperature is 33 ° C ± 1
The degree and humidity are 50% ± 5% (PH). Although the temperature and humidity differ depending on the season, comfortable sleep can be obtained by maintaining the temperature and humidity inside the bed appropriately. Bedding is what creates this temperature and humidity, and it can respond to seasonal changes by changing the type of futon and the combination of materials. However, Futon, which should give you comfortable sleep, may cause a fire due to the nature and structure of the material that is easily burned.
At times, there are cases where it burns to death. Under these circumstances, although combustion fibers have been developed in recent years, they have excellent flameproofness, but they have the drawbacks of high melting and shrinkability, large smoke emission, and the generation of toxic gas. It was Moreover, although it is a flame-retardant fiber, in fact, there are many cases in which it easily burns depending on the heating temperature. The amount of heat produced by the body decreases during sleep, and the body temperature tends to decrease, so that the bedding needs to retain heat. Also, during sleep, you are likely to sweat for several reasons, such as adjusting body temperature,
The part where the bedding comes into direct contact with the body is required to have sufficient hygroscopicity, and at the same time, if the temperature inside the bed exceeds a certain level, the user feels sleepiness due to "mudling", so moisture absorption, moisture permeability, and moisture release are prevented. Performance is required. Further, in order to prevent the temperature in the bed from escaping, the sleeping bedding is required to have a drape property (how to fit to the body) and a good body-covering property with a comfortable fit to the body. Furthermore, the bedding needs to be reasonably light. However, by performing flame-retardant treatment, heat retention, which is a necessary condition for Futon,
Moisture absorption / moisture permeability / moisture release performance is deteriorated, and in some cases, drapability and body covering property tend to be deteriorated. Conventional futons have many problems as described above, so they improve the flame retardancy (flameproofness) without impairing the original function of futons. The purpose of the present invention is to provide a safe futon that suppresses the occurrence of the problem as much as possible and a futon that is convenient for use.

[0004]

Therefore, in order to solve the above-mentioned problems, the present invention provides the original functionality of futon, that is, heat retention,
As a means for adding flame retardancy to Futon's heat insulating material (1) without impairing properties such as moisture absorption, moisture permeability, and moisture release, it is close to the fiber thickness of the material used as Futon's heat insulating material (1). It is considered that the flame-retardant substance made of fibers and made into short fibers (2) (fibers) should be almost evenly admixed with the fibers of the heat insulating material, and the aluminum foil pieces (3 It was thought that a better effect could be obtained by uniformly mixing) between the fibers (in the futon cotton). Therefore, as a result of various experiments, it was very effective to mix the novoloid fiber fiber (4) as a highly flameproof fiber into each heat insulating material (1) for futon (cotton, feather, wool, etc.). It has been found that the use of the novoloid carbon fiber fiber (5) or the novoloid activated carbon fiber fiber (6) made from the novoloid fiber as the raw material is more effective. That is, according to the present invention, the novoloid fiber as the highly flameproof fiber (flame retardant fiber) is used as the short fiber (fiber) (4), and the heat insulating material (1) for futon, that is, the heat insulating material (1) for the futon in the sealed container is provided at a constant ratio. Mix with cotton, feathers, wool, genuine cotton, synthetic fiber cotton, etc., mix them as evenly as possible between the fibers of these heat insulating materials (hereinafter referred to as "Futon's inner cotton") (1), and attach them. This attached heat insulation material (1 ')
The above-mentioned problem was solved by constructing the futon (7) by using the above as the inner cotton of the futon and putting it in the futon skin. The short fibers used may be novoloid carbon fiber fibers (5) or novoloid activated carbon fiber fibers (6) in addition to the novoloid fiber fibers (4), and the latter two have higher flameproofness and the like. . The novoloid fiber fiber (4) or the novoloid carbon fiber fiber (5) or the novoloid activated carbon fiber fiber (6) mixed and attached to the inner cotton (1) has a fineness of 2 denier to 10 denier and a diameter of 10
μ-50μ, fiber length 0.2mm-10mm, strength 0.7g
/ D to 1.7 g / d and an elongation in the range of 2% to 50% are sufficient, and most preferably 5 denier to 10 fibers.
Denier, diameter 20μ-40μ, fiber length 0.2mm-1
mm, strength 0.7 g / d to 1.3 g / d, elongation 2% to 10
%belongs to. Next, the mixing ratio of the novoloid fiber fiber (4) or the novoloid activated carbon fiber fiber (6) or the novoloid carbon fiber fiber (5) to the inner cotton (1) is 3% to 20 with respect to the inner cotton 10. %, And the most preferable mixing ratio is 5% to 15%. It is needless to say that the above three kinds of fiber fibers (4), (5) and (6) may be used alone or in a combination of two, or may be mixed in a combination of three, and the mixing ratio at that time is the above. Is the same as. Next, when the aluminum foil small piece (8) is mixed together, the diameter of the small piece (8) is 0.5 mm to 10 mm.
The range is 1 mm to 5 mm, and the compounding ratio thereof is 1% to 20%, preferably 3% to 10%, relative to the inner cotton 10.

Next, there is a case where the construction of one futon (10) is used as a connection assembly of a plurality of block bags (9).
According to the standard sizes of hanging butts and floor butts currently on the market, each of these is divided into a plurality of block bags (9), and the above-mentioned inner cotton is enclosed in the block bags (9). ) Are connected. In such a configuration, the bags (9) of the blocks may be non-detachably connected or may be removably connected. Of course, each block bag (9) is constructed so that the inner cotton can be freely taken in and out. In addition, the cover sheet (1) of Futon (10)
The storage part (1) for storing the individual block bags (9) in (2)
1) may be configured in plural, and the block bag (9) in which the inner cotton is sealed as described above may be stored in the storage portion (11) to form one futon (10).

[0006]

The present invention relates to a futon having the above-mentioned structure, and a novoloid fiber fiber formed by adhering and adhering an appropriate amount of fibers between the fibers of the futon inner cotton (1).
Although they are organic fibers, they are not only extremely flameproof even if they are not subjected to any special surface treatment, but they also emit a small amount of smoke during combustion and carbonization, and generate minimal toxic gas, which makes them heat resistant. It is also a very lightweight fiber. It is also a fiber that has excellent electrical insulation and friction characteristics. Next, novoloid carbon fiber is a difficult carbon fiber that is flexible,
Like novoloid fibers, it has good affinity with resins and rubber and also has excellent heat resistance. Of course, it also has the above-mentioned characteristics of the novoloid fiber. In addition to the characteristics of the above two fibers, the novoloid activated carbon fiber also has very high adsorption performance, extremely fast speed, and excellent tensile strength, bending strength, and flexibility. Since it is a fiber that has, even if the fiber having such properties is cut into short fibers and evenly mixed into the inside of the futon (10) inner cotton (1), various inner cotton (1) That is, the heat retention, hygroscopicity, moisture permeability and moisture release of futon are not impaired, and especially the heat retention is improved and maintained. The test results are shown in FIG. Moreover, since the weight of the futon is not increased, the comfort of sleeping is not impaired. Further, all of these fiber fibers have high smoke proof property and a small amount of smoke emission, and further, since the generation of toxic gas during combustion is extremely small, not only the flameproof effect at the time of fire is extremely large, but also due to smoke and toxic gas. The effect is that there is no damage.

Next, flameproof combustion experiments will be described. (1) Combustion test apparatus A combustion test box, a test piece support frame, and a basket conforming to the performance test standards of flameproof products. (2) Specimens Three specimens were randomly sampled from the same sample below and weighed 10 g. A. Genuine cotton B. Down (feather) C. Down Feather (Treatment Agent: Potassium Titanium Fluoride) D. DOWN (Novoloid fiber fiber-mixing; mixing ratio 1: 1) (Sample number n = 3) (3) Test method (45 ° mesenamine basket method) Pack the test body evenly in the basket and fix the lid. The basket was supported in a combustion test box. 4.5 from the center of the lower side of the test piece
The mesenamine was placed above cm in a manner that did not easily move. It was ignited by a match, and after igniting, the air around the fire source was kept quiet and left until combustion was completed. The carbonization length was measured as the maximum length in the longitudinal direction of the carbonized portion of the test piece, which was perspectively measured. (4) Test results The test results are shown in Table 1. The non-flameproof treated cotton and down have the maximum carbonization length of more than 120 mm in the former 3/3 and the latter 1/3, and the average value is 10 for both.
It was 0 mm or more. On the other hand, it is a flameproof product. The down feather had a maximum length and its average value were less than the standard value, and it complied with the standard as a flameproof product, but in the novoloid fiber fiber-mixed product, only the ignition part was partially carbonized and most of it burned. Since the carbonization did not occur, it was impossible to measure the carbonization length. From the above results, it was confirmed that the novoloid fiber-fiber mixture product has a remarkable flameproofing effect as compared with the conventional flameproofing product, and it was found that it is useful as a safer bedding material. The results are shown in Table 1 below.

Table 1

[0009] Next, an experimental example of the heat retention test of futon (measurement of the temperature inside the bed) using various heat insulation materials will be shown. (1) Test subject (hanging futon) 1 Cotton wool futon 2 Synthetic fiber cotton futon 3 Feather futon (conventional product: 100% down) 4 Feather futon of the present invention (feather. Novoloid fiber fiber-. Aluminum foil mixture: 5: 5: 1) ) The above 4 sizes are for S (single) / 150cm × 2
00 cm, floor / 105 cm × 200 cm, and all floor futons used were cotton wool futons. (2) Test method Various hanging futons were respectively laid on the floor futons of the above-mentioned fixed standard (105 x 200 cm), a temperature sensor was set at the center of the futon, and the futon was left for a fixed time (1 hour) to check the constant temperature. After that, the test subject (18-year-old woman, weight 45 kg,
He was allowed to sleep in each futon every other day at a height of 162 cm) and continuously recorded at intervals of 10 minutes until the temperature in the bed reached a constant level. After reaching a certain temperature, the subject goes out of the bed and presses the futon to be parallel to the floor futon to eliminate the space inside the bed, and then the temperature of the bed is changed every 10 minutes as described above. The temperature was measured and recorded until a certain temperature was reached. However, the temperature in the test chamber was controlled to 15 ° C ± 1 ° C. (3) Test results The test results are shown in Fig. 5. When the test subject entered the bed after the temperature in the bed reached a constant temperature of 16 ° C, the temperature in the bed rapidly increased for all the futons, but the feather futon of the present invention reached 33 ° C after 10 minutes. On the other hand, the conventional feather futon had a constant temperature of 33 ° C., 32 ° C. and 31 ° C. for 20 minutes, 30 minutes for a cotton wool futon, and 40 minutes for a synthetic fiber futon, respectively, and thereafter showed a continuous tendency. When the subject was taken out of the bed 3 hours after the start of the experiment, the bed temperature of each futon showed a tendency to decrease rapidly, but the feather futon of the present invention showed the slowest decreasing tendency, and 6 hours later (3 hours after the subject left the bed) Later), the temperature in the bed is 24.5 futons according to the present invention.
C., feather futon 22.5.degree. C., pure cotton futon 20.degree. C., synthetic fiber cotton futon 17.degree. As a result of considering the degree of rise and rate of rise in bed temperature and the degree of fall and rate of fall in bed temperature after leaving the subject, it was found that the feather futon of the present invention has the best heat retention.

Next, since each novoloid fiber has an affinity for synthetic resin products and is excellent in adsorptivity, when the futon inner cotton material is made of synthetic resin, the fibers of each novoloid fiber are synthetic inner cotton. Therefore, after being mixed and adsorbed evenly on the inner cotton, only the fiber fiber is separated from the inner cotton fiber and is not biased to only one side in the block storage bag for a long time ( At least the period of use of the inner cotton.) It exerts its action and effect. Also, when the futon is bent and put in and out, there is no inconvenience in use because the fiber fiber itself has flexibility and is made into a short fiber. Moreover, since it has excellent flameproofness and the generation of toxic gas or smoke when burning is minimal or no, there is no fear of an accident during a fire due to these. Of course, these effects do not change in spring, summer, autumn, and winter, and as mentioned above, flameproofness (flame retardancy) is an inherent property of the fiber itself, and therefore the labor of imparting flame retardancy by chemical treatment as in conventional products is also required. It is economical because it does not require any cost. Next, when the futon has an assembly structure of block bags, it is very convenient for washing (only dirty block bags can be washed), replacement of inner cotton, and storage in a narrow space. Further, when the block bag is constructed as an integrated structure, it improves the drapeability as a sleeping bed and a body-covering property with a comfortable fit to the body. Also, since one piece of futon is divided into a plurality of block bags, it is difficult to breed and move mites to a minimum, and it is also convenient for drying futon. It should be noted that mites rarely invade and propagate in the futon of the present invention in which a novoloid fiber fiber or the like is used and mixed, but the cause thereof is still unknown, but it is still under study. Furthermore, by creating the contents of each capsule individually with feather, small feather, wool, genuine cotton, synthetic fiber, by the combination,
More economical and functional. For example, for allergic patients, the part that touches the mouth should be made of cotton to avoid feathers, and if the feet are cold, the hem of the futon should be made of wool. In addition to the warmth (heat retention) of the elderly, I want a sense of weight. In this case, it is possible to use feathers at the feet and around the shoulders and use cotton for the chest and waist. In other words, the functionality of futon can be adjusted according to the actual living conditions. Further, the functionality of the futon can be adjusted by double-inserting the block bag into the block bag storage portion formed in the futon cover. Further, when a small piece of aluminum foil is mixed with the fiber fiber used in the present invention, it becomes possible to dramatically improve the flameproof effect and the heat retaining effect due to the flame retardancy of the aluminum foil.

[Problems to be Solved by the Invention] Temperature and humidity in a bed are the most important conditions for comfortable sleep. In the area where the temperature and humidity inside the bed during sleep are comfortable, the temperature is 33 ° C ± 1
The degree and humidity are 50% ± 5% (RH). Although the temperature and humidity differ depending on the season, comfortable sleep can be obtained by maintaining the temperature and humidity inside the bed appropriately. Bedding is what creates this temperature and humidity, and it can respond to seasonal changes by changing the type of futon and the combination of materials. However, Futon, which should give you comfortable sleep, may cause a fire due to the nature and structure of the material that is easily burned.
Occasionally, there are cases where it is burned to death. Under these circumstances, although combustion fibers have been developed in recent years, they have excellent flameproofness, but they have the drawbacks of high melting and shrinkability, large smoke emission, and the generation of toxic gas. It was Moreover, although it is a flame-retardant fiber, there are many cases in which it is easily burned depending on the heating temperature. The amount of heat produced by the body decreases during sleep, and the body temperature tends to decrease, so that the bedding needs to retain heat. Also, during sleep, you are likely to sweat for several reasons, such as adjusting body temperature,
The part where the bedding comes into direct contact with the body is required to have sufficient hygroscopicity, and at the same time, if the temperature inside the bed exceeds a certain level, the user feels sleepiness due to "mudling", so moisture absorption, moisture permeability, and moisture release are prevented. Performance is required. Also, in order to prevent the temperature inside the bed from escaping, it is required that the bedding have good drapeability (how to fit to the body) and good body covering with a comfortable fit to the body. Furthermore, the bedding needs to be reasonably light. However, by performing flame-retardant treatment, heat retention, which is a necessary condition for Futon,
It tends to deteriorate the moisture absorption, moisture permeability, and moisture release properties, and in some cases, also deteriorates the drape property and body covering property. Conventional futons have many problems as described above, so they improve the flame retardancy (flameproofness) without impairing the original function of futons. The purpose of the present invention is to provide a safe futon that suppresses the occurrence of the problem as much as possible and a futon that is convenient for use.

[0004]

Therefore, in order to solve the above-mentioned problems, the present invention provides the original functionality of futon, that is, heat retention,
As a means for adding flame retardancy to Futon's heat insulating material (1) without impairing properties such as moisture absorption, moisture permeability, and moisture release, it is close to the fiber thickness of the material used as Futon's heat insulating material (1). It is considered that a flame-retardant substance made of fibers and made into short fibers (2) (fibers) should be admixed with the fibers of the heat insulating material almost evenly, and further, aluminum foil pieces (8) It was thought that a better effect could be obtained if the ingredients were evenly mixed between the fibers (in the futon cotton). Therefore, as a result of various experiments, mixing the novoloid fiber (4) as a highly flameproof fiber into each heat insulating material (1) for futon (cotton, feather, wool, etc.) is extremely successful. It was further found that the use of the novoloid carbon fiber fiber (5) or the novoloid activated carbon fiber fiber (6) made from the novoloid fiber as the raw material would bring about even greater effect. That is, in the present invention, the novoloid fiber as the highly flameproof fiber (flame-retardant fiber) is used as the short fiber (fiber) (4), and the heat insulating material (1), that is, cotton, for futon in the sealed container at a constant ratio. , Feather, wool, cotton,
Mixing with synthetic fiber cotton etc., these heat insulation materials (hereinafter referred to as "Futon's inner cotton") (1) are mixed evenly between the fibers of the heat insulation material and adhered, and the adhered heat insulation material (1 The above problem has been solved by using ′) as the inner cotton of the futon and putting it in the futon skin to form the futon (7). The short fibers to be used may be novoloid carbon fiber fibers (5) or novoloid activated carbon fiber fibers (6) in addition to the novoloid fiber fibers (4), and the latter two have higher flameproofness and the like. The novoloid fiber fiber (4) or the novoloid carbon fiber fiber (5) or the novoloid activated carbon fiber fiber (6) mixed and attached to the inner cotton (1) has a fineness of 2 denier to 10 denier, a diameter of 10 μ to 50 μ, and a fiber length of 0. 2 mm to 10 m
m, strength 0.7 g / d to 1.7 g / d, elongation 2% to 50
% Range is sufficient, most preferably fiber 5 denier to 10 denier, diameter 20 μ to 40 μ, fiber length 0.2 mm to 1 mm, strength 0.7 g / d to 1.3 g.
/ D and elongation of 2% to 10%. Then inner cotton (1)
The mixing ratio of the novoloid fiber fiber (4) or the novoloid activated carbon fiber fiber (6) or the novoloid carbon fiber fiber (5) is 3 to 10 inner cotton.
It may be in the range of 20, and the most preferable mixing ratio is 5 to 1.
It is 5. The above three types of fiber fibers (4)
Needless to say, (5) and (6) may be used alone or in a combination of two, or in a combination of three, and the mixing ratio in that case is the same as the above. Next, when the aluminum foil small piece (8) is mixed together, the diameter of the small piece (8) may be in the range of 0.5 mm to 10 mm, preferably 1 mm to 5 mm, and the compounding ratio thereof is It is 1 to 20, and preferably 3 to 10 with respect to cotton 10.

Next, there is a case where the construction of one futon (10) is used as a connection assembly of a plurality of block bags (9).
According to the standard sizes of hanging butts and floor butts currently on the market, each of these is divided into a plurality of block bags (9), and the above-mentioned inner cotton is enclosed in the block bags (9). ) Are connected. In such a configuration, the bags (9) of the blocks may be non-detachably connected or may be removably connected. Of course, each block bag (9) is constructed so that the inner cotton can be freely taken in and out. In addition, futon (10) cover sheet (1

[0006]

The present invention is a futon having the above-mentioned structure. However, a novoloid fiber fiber or the like obtained by mixing and adhering an appropriate amount between the fibers of the futon inner cotton (1) is an organic fiber. However, not only the fiber itself has extremely high flameproofness without special surface treatment, it produces a small amount of smoke during combustion and carbonization, produces minimal toxic gas, and is heat resistant and extremely lightweight. It is also a fiber. It is also a fiber that has excellent electrical insulation and friction characteristics. Next, novoloid carbon fiber is a difficult carbon fiber that is flexible,
Like novoloid fibers, it has good affinity with resins and rubber and also has excellent heat resistance. Of course, it also has the above-mentioned characteristics of the novoloid fiber. In addition to the characteristics of the above two fibers, the novoloid activated carbon fiber also has very high adsorption performance, extremely fast speed, and excellent tensile strength, bending strength, and flexibility. Since it is a fiber that has, even if the fiber having such properties is cut into short fibers and evenly mixed into the inside of the futon (10) inner cotton (1), various inner cotton (1) That is, the heat retention, hygroscopicity, moisture permeability and moisture release of futon are not impaired, and especially the heat retention is improved and maintained. The test results are shown in FIG. Moreover, since the weight of the futon is not increased, the comfort of sleeping is not impaired. Furthermore, all of these fibers have high smoke resistance and low smoke emission, and because they emit very little toxic gas during combustion, they not only have a great flameproof effect during a fire, but also damage caused by smoke and toxic gas. It has the effect of being unnecessary.

Next, flameproof combustion experiments will be described. (1) Combustion test apparatus A combustion test box, a test piece support frame, and a basket conforming to the performance test standards of flameproof products. (2) Specimens Three specimens were randomly sampled from the same sample below and weighed 10 g. A. Genuine cotton B. Down (feather) C. Down Feather (Treatment Agent: Potassium Titanium Fluoride) D. Down (novoloid fiber fiber mixing; mixing ratio 1: 1) (Sample number n = 3) (3) Test method (45 ° Mesenamin basket method) Pack the test body evenly in the basket and fix the lid, The basket was supported in a combustion test box. 4.5 from the bottom center of the test piece
The mesenamine was placed above cm in a manner that did not easily move. It was ignited by a match, and after igniting, the air around the fire source was kept quiet and left until combustion was completed. The carbonization length was measured as the maximum length in the longitudinal direction of the carbonized portion of the test piece, which was perspectively measured. (4) Test results The test results are shown in Table 1. The non-flameproof treated cotton and down have the maximum carbonization length of more than 120 mm in the former 3/3 and the latter 1/3, and the average value is 10 for both.
It was 0 mm or more. On the other hand, the down-feather, which is a flameproof product, conformed to the standard as a flameproof product with the maximum length and its average value being less than the standard value, but in the novoloid fiber fiber mixture, only the ignition part was partially carbonized. Since most of them did not burn and did not lead to carbonization, it was impossible to measure the carbonization length. From the above results, it was confirmed that the novoloid fiber-fiber mixture product has a remarkable flameproofing effect as compared with conventional flameproofing products, and it was found that it is useful as a safer bedding material. The results are shown in Table 1 below.

00 cm, floor / 105 cm × 200 cm, and all floor futons used were cotton wool futons. (2) Test method Various hanging futons were respectively laid on the floor futons of the above-mentioned constant standard (105 × 200 cm), and a temperature sensor was set at the center of the futon and left for a fixed time (1 hour) to check the fixed temperature. After that, the test subject (18-year-old woman, weight 45 kg,
He was allowed to sleep in each futon every other day at a height of 162 cm) and continuously recorded at intervals of 10 minutes until the temperature in the bed reached a constant level. After reaching a certain temperature, the subject goes out of the bed and presses the futon to be parallel to the floor futon to eliminate the space inside the bed, and then the temperature of the bed is changed every 10 minutes as described above. The temperature was measured and recorded until a certain temperature was reached. However, the temperature inside the test chamber was controlled at 15 ° C ± 1 ° C. (3) Test results The test results are shown in Fig. 5. When the test subject entered the bed after the temperature in the bed reached a constant temperature of 16 ° C, the temperature in the bed rapidly increased for all the futons, but the feather futon of the present invention reached 33 ° C after 10 minutes. On the other hand, the conventional feather futon had a constant temperature of 33 ° C., 32 ° C. and 31 ° C. for 20 minutes, 30 minutes for a cotton wool futon, and 40 minutes for a synthetic fiber futon, respectively, and thereafter showed a continuous tendency. When the subject was taken out of the bed 3 hours after the start of the experiment, the bed temperature of each futon showed a tendency to decrease rapidly, but the feather futon of the present invention showed the slowest decreasing tendency, and 6 hours later (3 hours after the subject left the bed) Later), the temperature in the bed was 24.5 down in the present invention.
C., futon 22.5.degree. C., cotton futon 20.degree. C., synthetic fiber cotton futon 17.degree. As a result of considering the degree of rise and rate of rise in bed temperature and the degree of fall and rate of fall in bed temperature after leaving the subject, it was found that the feather futon of the present invention has the best heat retention.

Next, since each novoloid fiber has an affinity for synthetic resin products and is excellent in adsorptivity, when the futon inner cotton material is made of synthetic resin, each novoloid fiber becomes a synthetic inner cotton. Since it is adsorbed, even after being mixed and adsorbed evenly on the inner cotton, only the fiber fibers do not separate from the inner cotton fiber and shift to only one side in the block storage bag for a long time (at least Use period of inner cotton.) It exerts its action and effect. Also, when the futon is bent and put in and out, there is no inconvenience in use because the fiber fiber itself has flexibility and is made into a short fiber. Moreover, since it has excellent flameproofness and the generation of toxic gas or smoke when burning is minimal or no, there is no fear of an accident during a fire due to these. Of course, these effects do not change in spring, summer, autumn, and winter, and as mentioned above, flameproofness (flame retardancy) is an inherent property of the fiber itself, and therefore the labor of imparting flame retardancy by chemical treatment as in conventional products is also required. It is economical because it does not require any cost. Next, when the futon has an assembly structure of block bags, it is very convenient for washing (only dirty block bags can be washed), replacement of inner cotton, and storage in a narrow space. Further, when the block bag is constructed as an integrated structure, it improves the drape property as a sleeping bed and the body covering property with a comfortable fit to the body. Also, since one piece of futon is divided into a plurality of block bags, it is difficult to breed and move mites to a minimum, and it is also convenient for drying futon. It should be noted that mites rarely invade and propagate in the futon of the present invention in which the novoloid fiber fiber or the like is mixed, but the cause thereof is not yet determined, but it is still under study. Furthermore, by creating the contents of each capsule individually with feather, small feather, wool, genuine cotton, synthetic fiber, by the combination,
More economical and functional. For example, if you have allergies and want to avoid feathers in the area around your mouth, use cotton for those who have cold feet, and use wool in the hem of the futon, and if you want warmth (heat retention) and a feeling of weight in the elderly. It is possible to use it by using feathers around the feet and shoulders and using cotton in the chest and waist. In other words, the functionality of futon can be adjusted according to the actual living conditions. Furthermore, the functionality of the futon can be adjusted by double-inserting the block bag into the block bag storage portion formed in the futon cover. Further, when a small piece of aluminum foil is mixed with the fiber fiber used in the present invention, it becomes possible to dramatically improve the flameproofing effect and the heat retaining effect due to the flame retardancy of the aluminum foil.
