Description

The present invention relates to a comforter suitable for use in medical relations such as hospitals, medical facilities, and home care.

In traditional medical comforters used in hospitals, medical facilities, home care, etc., the same comforter is used throughout the year because it is too hot in summer and cold in winter for shared use in summer and winter. If you use summer comforters in summer or only thick winter comforters in winter, there will be no draping. Had to use. It was necessary to secure a storage place during the period when it was not used, such as leaving summer futons in winter and winter comforters in summer, leaving the futons to a contractor.

In addition, down comforters have been used for weight reduction, but as the side fabrics use densely packed fabric on both the front and back sides to prevent the feathers from popping out, The air does not move easily and has heat insulation, but in winter it is difficult to keep the body temperature inside and in summer it is difficult to release the heat.

As the comforter, cotton made of cotton or synthetic fiber cotton is usually used as the batting, and the front and back are sewn in a bag shape using the same fabric, and the batting is stored therein. An important requirement for the characteristics of the fabric as the side covering the batting used here is that the fibers constituting the batting do not jump out. In use, it is usually covered with a comforter cover. The role of this comforter cover is to improve the touch. It is in the point of keeping it clean by exchanging when dirt adheres to the surface.

  The present invention has been made in view of the current situation as described above, and provides a comforter that can be used throughout the year in response to cold and heat, and does not have any trouble in the storage location. It is intended.

The present invention solves the above problems,
1) A comforter using fabrics with different breathability as side fabrics for covering the front and back sides, and the difference in breathability between the front and back fabrics according to the JIS L1096A method is 40 cm ³ / cm ² / sec or more. A comforter in which the breathability of the smaller fabric is 50 cm ³ / cm ² / sec or less,
2) A comforter using fabrics with different cover factors as front and back sides covering the batting, the difference between the cover factors of the front and back fabrics is 1800 or more, and the cover factor with the larger cover factor is 200 or more The comforter above,
3) The above-mentioned comforter, in which either or both of the front and back sides covering the batting are subjected to water repellent treatment,
4) The above-mentioned comforter that has been treated with cotton
5) A comforter cover using fabrics with different breathability as the fabric of the front and back, the difference in breathability of the fabric of the front and back according to the JIS L1096A method is 40 cm ³ / cm ² / sec or more, A gist cover is characterized in that the breathability of the fabric is 50 cm ³ / cm ² / sec or less.

In the comforter of the present invention, fabrics with different breathability are used as the front and back sides covering the batting, so that the surface that the body hits at bedtime is the side of the highly breathable side, and the opposite side is less breathable If it is on the side land side, the air warmed by the body temperature stays in the batting part and prevents it from escaping outside, so the body temperature is kept warm, and the outside side land shuts out cold air, so it sleeps warmly in winter can do.

If the side where the body hits at bedtime is the side with a low breathability side and the opposite side is the side with a high breathability side, it will be easier to release the heat accumulated in the filling due to body temperature, It feels cool in summer without stuffiness.

The comforter according to the present invention can be used as a comforter for both summer and winter throughout the year.

The effect of the comforter of the present invention is that, as the comforter cover, fabrics having different breathability are used as front and back fabrics, the difference in breathability between the front and back fabrics according to the JIS L1096A method is 40 cm ³ / cm ² / sec or more. It can also be obtained by covering a normal comforter with a comforter cover sewed using a fabric whose air permeability of the smaller fabric is 50 cm ³ / cm ² / sec or less.

The comforter according to the present invention can be used with only one sheet throughout the year by reversibly using comforters that have been used separately for summer and winter.

FIG. 1 shows a cross section of a comforter of a typical example of the present invention. In FIG. 1, a comforter 1 of the present invention is composed of a fabric used as a front side fabric 3 covering a batting 2 and a fabric used as a back side fabric 4. The fabric used as the front side fabric 3 and the fabric used as the back side fabric 4 are different in breathability or cover factor.

In the present invention, when the air permeability of the front and back sides is different, it is preferable that there is a difference of 40 cm ³ / cm ² / sec or more in the air permeability according to the A method defined in JIS L1096, and the air permeability is small. It is preferable that the air permeability of the fabric is 50 cm ³ / cm ² / sec or less. Using such a comforter, when sleeping on the side where the body abuts on the side of the highly breathable side and the opposite side on the side of the side where the air permeability is small, the air warmed by the body temperature is the inside breathable Easy to pass through large side areas and stay in the batting part, prevent the outer side areas with low air permeability from escaping out of the warm air, and prevent the outside air from entering it can. When going to bed in the reverse state, air can easily come out from the outer side where the air permeability is high, and the heat dissipation effect can make it difficult to stuffy.

In the present invention, examples of the fabric that can be used as the side fabric include woven fabric, knitted fabric, and nonwoven fabric. A knitted fabric or nonwoven fabric having a relatively high air permeability can be used as the highly air permeable fabric of the present invention. Of course, woven fabric can be used for both the front and back sides.
The fabric used as the side fabric may be subjected to a water-repellent treatment using a fluorine-based water-repellent resin or a silicon-based water-repellent resin. When a fabric having a water repellent finish is used for the side fabric, it is possible to prevent the batting from containing moisture due to moisture, sweat, or the like, and to suppress a decrease in the warming action of the futon.

In the present invention, when the front and back sides are woven fabrics and the cover factors are different, it is preferable that the cover factors of the front and back fabrics have a difference of 200 or more, and the cover factor with the larger cover factor is 1800. The above is preferable. In this case, the cover factor is calculated by the following equation (1).
Cover factor = D ^1/2 × N + E ^1/2 × M (1)
Here, D: warp fineness (dtex), E: weft fineness (dtex), N: warp density (line / 2.5 cm), M: weft density (line / 2.5 cm).
When the warp fineness and the weft fineness are not displayed as “dtex”, they may be calculated by a conversion formula. For example, when the warp fineness D is displayed by the British cotton count S, the following formula (2) is used. What is necessary is just to convert and use.
D = 5905 / S (2)

A fabric with a large cover factor is less breathable than a fabric with a small cover factor, so the side that the body touches is the side with the side with the small cover factor, and the opposite side is the side with the side with the large cover factor. Then, the air warmed by the body temperature easily passes through the inner side with high air permeability and stays in the batting part, preventing the outer side with low air permeability from escaping out of the warm air. , Can prevent the outside air from entering.

The batting used in the comforter of the present invention is not limited as long as it is made of cotton, wool wool, synthetic cotton such as polyester cotton or the like, or a mixture of these cottons. . Moreover, it is also preferable that the cotton is made by mixing low-melting synthetic fiber cotton with them, heat-treating them, and bonding the cottons together so that the single fibers are hardly separated and scattered.

As shown in FIG. 2, the comforter of the present invention can use a double side. In this case, one side is a side using a fabric having a small air permeability, a fabric having a breathability of 50 cm ³ / cm ² / sec or less is used for either the inner side fabric 5 or the outer side fabric 6, and this fabric is used for the remaining side fabric. Use a fabric with the same breathability as that of, or with greater breathability. For the inner fabric 7 and the outer fabric 8 on the side where the fabric having high air permeability on the one side is used, a fabric having a breathability of 40 cm ³ / cm ² / sec or more larger than that of the fabric having low breathability is used. The inner fabric 7 and the outer fabric 8 may be the same fabric or different fabrics.

The comforter of the present invention is not completely covered with the outer fabric as described above, but the outer fabric 6 can be used only on one side as shown in FIG. Even when the outer side is used, it is possible to obtain the effect of using the water-repellent cloth using a cloth subjected to a water-repellent process using a fluorine-type water-repellent resin or a silicon-type water-repellent resin.

Moreover, in the comforter of this invention, it is preferable to change the color and the pattern of the front and back sides, and to make it easy to understand which side is in use. Similarly, when covering and using the outside ground, it is also easy to understand if the colors and patterns on both sides of the outside ground are changed.

In the comforter of the present invention, it is preferable to perform a cotton fastening process such as a quilting process or a Japanese binding process in a state where the padding of FIG. When quilting is performed, it is preferable to use different colors for the yarns used on the front and back sides, since this helps to identify surfaces having different air permeability.

The effect of the comforter of the present invention can also be obtained by covering a normal comforter with a comforter cover that is sewn using differently breathable fabrics as the front and back fabrics. In this case, the comforter cover has an air permeability difference of 40 cm ³ / cm ² / sec or more according to JIS L1096A method between the front and back fabrics, and the air permeability of the fabric with the smaller air permeability is 50 cm ³ / cm ² / sec or less. It is obtained by sewing using a fabric that is.
