(Japanese Unexamined Patent Publication (Kokai)), a short fiber combined with a low melting point component to form an aggregate (Japanese Unexamined Patent Publication (Kokai) No. 5-76388), and a three-dimensional structure fabric having a multi-woven structure and using a high shrinkage yarn as a warp (special Kaihei 6-128837) is known.

れない。However, the conventional cushion structure has a hard surface, and when worn, the friction with the skin is high, and the skin is sore especially for an old man or a bedridden person in a hospital. When used in general, it is covered with a side cloth such as a woven fabric, but the surface of the cushion structure is largely affected, and thus the surface feels hard. In addition, a urethane foam that is usually used as a cushioning material gives a high stuffiness when worn. Also, regarding the cushioning property, the surface of the corrugated board cushion tends to be smooth,
The thickness is hard to come out because it is not a multi-layer. For this reason, during wear, the ability to follow the body shape is not good, especially the bone part of the human body,
Stress concentrates on hard parts and protruding parts. Since the surface is smooth, it is difficult to form a space with the human body, so the air permeability is low and it easily gets damp. Further, since the thickness is thin, only cushion material having low cushioning property, rough hardness and strong bottoming can be obtained.

必要となる、厚物の場合は縫製が困難になるといった問
題点がある。In the cushioning material in which the flat backside ground structure and the mesh or the flat front side cloth are connected, the ventilation space is small and stuffy because the thickness is thin, and the stress is concentrated because the surface is flat, and the connection yarn is connected. However, there is a problem that it is necessary to increase the number of steps to do so, and it becomes difficult to sew in the case of a thick material.

しやすい。Further, it is technically difficult to provide a cushion material made of a thick cloth using a knitted fabric so as to have a cushioning property, and it is thin, has a low cushioning property, and has a strong bottoming feeling. I can only get things. On the other hand, it is difficult to form a ventilation space in the warp and weft directions in terms of the structure, and it is easy to get stuffy. Further, since the mesh size is small and the local space is small, even if a hard portion is hit, it cannot be partially deformed and the stress cannot escape, so that the stress is easily concentrated.

ッション材に当った場合、局部的変形が起こりにくいの
で応力集中を生じる。又、繊維間結合に低融点成分を使
用しているため、滅菌等の処理を行うことが出来ない。In the case of a cushion material composed of an aggregate of short fibers, when the hard material hits the cushion material with a low air permeability and a stuffy feeling, local deformation is less likely to occur and stress concentration occurs. In addition, since the low melting point component is used for the fiber-to-fiber bond, sterilization or the like cannot be performed.

く取扱性が不良であるといった欠点があった。In the case of a three-dimensional fabric having a multi-woven structure,
The stress distribution is relatively good, but there is a problem that it is hard when worn. That is, conventionally, when worn, the contact is hard and the friction with the skin is strong, and the thickness is thin,
Coarse and low cushioning, stress concentration during wearing,
It has the drawbacks that it is easy to cause pain and blood flow obstruction, the ventilation space collapses during use and the air permeability deteriorates, and it gets damp, and it is difficult to bend during storage and washing and the handling is poor.

度なクッション性が得られない。The cushion structure of the present invention is an integral laminate of a woven and knitted fabric and a non-woven fabric. The cushion structure has an air permeability of 20 to 300 cc / cm for both the non-woven fabric part and the woven and knitted fabric part.
2 / sec. If it is less than 20 cc / cm 2 / sec, it becomes stuffy when worn. 300 cc / cm 2
If it exceeds / sec, the air permeability is too high, and the heat retention becomes insufficient. The thickness of the woven / knitted portion is 4 to 50 mm. It is preferably 20 to 35 mm. The thickness of the woven and knitted fabric is 4
If it is less than mm, the cushioning property for supporting the whole is lowered to become coarse and hard, the air circulation space during wearing becomes small, and stuffiness is likely to occur. In addition, the feeling of bottoming becomes large, which is not preferable. If the thickness of the woven or knitted portion exceeds 50 mm, there is a problem that the sinking becomes large when worn. Hardness is 25%
The compression hardness is 2 to 40 kg. If it is less than 2 kg, a feeling of bottoming occurs, and if it exceeds 40 kg, it is too hard to obtain an appropriate cushioning property when worn.

密着が大きくなり着用時に蒸れが発生する。The surface hardness of the non-woven fabric is 20-80. When the surface hardness of the non-woven fabric exceeds 80, friction with the skin becomes strong and the skin is damaged by abrasion when worn. When the surface hardness of the non-woven fabric is less than 20, it is too soft and the adhesion to the skin becomes large, causing stuffiness when worn.

If it exceeds 0 mm, the close contact with the body becomes large, which may cause stuffiness when worn. If it is less than 1 mm, the surface hardness becomes high, and proper cushioning properties cannot be obtained when worn.

Is. When the surface hardness of the cushion structure exceeds 60, the resistance on the skin surface when worn becomes strong even when a nonwoven fabric is laminated. When the surface hardness of the cushion structure is less than 10, there is a problem in surface durability when worn.

に問題がある。Further, in order to facilitate stress distribution during wearing, it is preferable to provide convex portions with a height of 2 to 15 mm and a pitch of 5 to 40 mm on the surface. When the height of the convex portion is less than 2 mm, the contact area with the body surface is large, the air flow is poor, and stuffiness occurs. When the height of the convex portion exceeds 15 mm, when the convex portion is subjected to a load, the convex portion may collapse or there is a problem in durability.
【0015】ピッチが5mm未満では、空気の流通が悪

局部的破壊が生じる。If the pitch is less than 5 mm, the air flow is poor and stuffiness is likely to occur. If the pitch exceeds 40 mm, the contact area is too small and stress concentrates on the contact portion, causing local fracture.
【0016】不織布は、低融点成分や結合樹脂成分を含

0% is preferable. The elongation of the non-woven fabric is 80% in both the weft direction and the warp direction.
If it is less than the above range, the surface becomes hard due to lack of flexibility. If the elongation of the non-woven fabric exceeds 100% both in the weft direction and in the weft direction, the close contact with the body increases and the product becomes stuffy when worn. The heat shrinkage rate of the nonwoven fabric is preferably 3% or less in both warp and weft directions. When the heat shrinkage rate of the nonwoven fabric exceeds 3%, it becomes difficult to perform the sterilization treatment.

The porosity is preferably 90 to 97%. If the porosity is less than 90%, it is difficult to achieve air permeability and reduction of stuffiness when worn. If the porosity exceeds 97%, the durability as a cushion structure becomes insufficient.
