Description

  The present invention has a function to discharge unpleasant moisture and odor such as sweat and body odor emitted from the body during sleep, and to maintain an optimal bed and indoor environment, and provides a more comfortable sleep even when used for a long time. A mattress that enables

BACKGROUND ART Conventionally, there is a more practical deodorizing pad that is considered for repeated use in washing (for example, see Patent Document 1).
Japanese Utility Model Registration No. 3078903 (page 1-2, FIG. 2) In addition, without performing deodorizing processing on the entire nonwoven fabric or processed cotton in advance, deodorizing processing is performed using a sewing thread having a deodorizing function. There is a deodorizing bed pad which is inexpensive by performing quilting processing using unprocessed ordinary cotton and non-woven cloth such as nonwoven cloth, and which can recover its deodorizing function even after washing. Japanese Patent No. 3002449 (pages 1-3, FIG. 1)

  The deodorant pad of the above-mentioned patent document 1 uses an acrylic deodorant ammonia deodorant cotton stuffed inside, and uses a cloth made of a mixed spun ester cotton with good washability and no shrinkage on the outer material, and quilts it. The process is characterized in that ammonia is adsorbed and deodorized. However, in the above structure, even if deodorization inside the pad can be realized by the ammonia deodorizing cotton, it does not reach the point where the inside of the pad exhibits the air permeability and dehumidifying effect.

  In addition, the deodorizing bed pad of Patent Document 2 cited above uses a deodorizing cellulose fiber obtained by a production method in which methacrylic acid is graft-copolymerized to a cellulose fiber in an aqueous solution containing hydrogen peroxide and a ferrous salt. The fabric is spun into a sewing thread, and ordinary sewing cotton that has not been deodorized is covered with a cloth and quilted using the sewing thread. However, according to the above configuration, the location where the deodorizing effect is exerted is limited to only the quilted portion using the deodorizing cellulose fiber, so that the deodorizing effect of the entire bedding over a wide range cannot be obtained.

  In view of the above points, the present invention is to provide a mattress that can obtain high air permeability and can exhibit a wide range of high deodorizing effect when lying down by such air permeability.

  In order to solve the above-mentioned problem, a mattress of the present invention is a mattress having an outer peripheral portion formed in a thick-walled shape, and is characterized in that a highly permeable sheet is attached to the outer peripheral portion. Further, it is preferable to attach a deodorizing nonwoven fabric to at least one side of the sheet. Further, it is preferable that the sheet and the nonwoven fabric are bonded by ultrasonic quilting.

  By attaching a highly air-permeable sheet to the outer peripheral portion, when turning over while sleeping, the air inside the futon is ventilated from the outer peripheral portion and the moisture trapped inside can be discharged. In addition, by attaching the deodorant nonwoven fabric to the outer peripheral portion, air ventilated from the outer peripheral portion is deodorized, so that a wide range of deodorization can be realized not only around the futon but also in the entire bedroom. Furthermore, by bonding the sheet and non-woven fabric by ultrasonic quilting, the air permeability of the material itself can be maintained by point-like bonding, preventing the occurrence of thread breakage and fraying even during long-term use. it can.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The mattress 1 shown in the figure has a core made of solid cotton 2 having an appropriate hardness, and middle members 3 and 4 having high buffering properties are arranged on upper and lower portions of the solid cotton 2. The middle members 3 and 4 are covered with a cloth 5, and the ends of the middle members 3 and 4 are sewn with hem tape 6. The middle members 3 and 4 disposed on the upper portion and / or the lower portion of the solid cotton 2 are subjected to a normal quilting process.

  Around the mattress 1, an outer peripheral portion 10 formed in a thick shape is formed. The outer peripheral portion 10 is an end portion of the solid cotton 2 and the middle members 3 and 4 and is formed between the hem tapes 6. The outer peripheral portion 10 is provided with a highly air-permeable mesh sheet 11. ing.

  The sheet 11 is made of a synthetic fiber which is thermally melted by heating or a blended material of a chemical fiber and a natural fiber, and is preferably formed in a mesh shape so as to obtain a particularly high air permeability. As the sheet 11, for example, a Russell jersey net having an 8-course diamond structure, 100% nylon, a density of 22 courses / inch, a lateral density of 18 wells / inch, a basis weight of 360 g / 105 cm × 1 m, or the like is suitably used. By attaching the highly air-permeable mesh-shaped sheet 11 to the outer peripheral portion 10, when turning over while sleeping, the air inside the futon is ventilated from the outer peripheral portion 10 and the moisture or odor trapped inside is discharged. be able to.

  The sheet 11 may be provided on one side surface of the nonwoven fabric 12 as shown in FIG. 3, or may be provided on both surfaces in a state where the nonwoven fabric 12 is taught (not shown).

  As another preferable example of the mattress of the present invention, it is preferable to attach a deodorant nonwoven fabric 12 to the outer peripheral portion 10. The nonwoven fabric 12 is formed by using fibers containing or adhering to the deodorant composition, or by adhering the deodorant composition to an existing nonwoven fabric. In particular, the nonwoven fabric 12 is obtained by a graft copolymerization reaction of methacrylic acid with cotton fiber, hemp fiber or rayon fiber, and the graft ratio of methacrylic acid to the fiber is 7 to 15% by weight. It is preferable to use modified cellulose fibers. This modified cellulose fiber is a technique known as a modified cellulose fiber disclosed in Japanese Patent No. 3239146. Specifically, a modified cellulose fiber obtained by graft-copolymerizing methacrylic acid with a cotton fiber, a hemp fiber or a rayon fiber, wherein the grafting ratio of methacrylic acid to the fiber is 7 to 15% by weight. It is. By attaching the nonwoven fabric 12 to the outer peripheral portion 10, the air ventilated from the outer peripheral portion is deodorized, so that it is possible to deodorize not only the surroundings of the futon but also the entire bedroom over a wide range.

  As another preferred example of the mattress of the present invention, as shown in FIG. 4, it is preferable to bond the sheet 11 and the nonwoven fabric 12 by ultrasonic quilting having a large number of point-like bonding portions 13. Ultrasonic quilting is a processing technique in which a material itself is bonded to a plurality of layers of material by frictional heat generated by ultrasonic vibration, and has been conventionally known. By using the above-described ultrasonic quilting, the sheet 11 and the nonwoven fabric 12 are welded by frictional heat generated by ultrasonic vibration, and the air permeability and water permeability of the material itself are not impaired. Also, unlike ordinary multi-needle quilting sewing, there is no through hole with a needle between the materials, and there is no thread breakage or thread fraying because no thread is used. Furthermore, even in long-term use, the adhesive state between the sheet 11 and the nonwoven fabric 12 can be reliably maintained.

Next, an example of use and operation of the mattress of the present invention will be described with reference to (a), (b) and (c) of FIG.
(A) is a state lying on the central portion of the mattress 1, in which case the cotton 2 and the middle materials 3 and 4 are compressed by the weight of the body, and the air inside the mattress 1 passes through the sheet 11 on both sides. It is discharged from the outer peripheral portion 10. In addition, when the nonwoven fabric 12 is attached, the air that has passed through the outer peripheral portion 10 is discharged into the room in a deodorized state.
(B) and (c) show a state in which the mattress has been turned over on the mattress 1. In this case, air is discharged from the outer peripheral portion 10 on the turning side and external air is discharged from the outer circumferential portion 10 on the opposite side. It is sucked into.
