Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a futon cotton having excellent cushioning properties.

[Conventional technology]

It is desirable that the bedding material has moderate softness, moderate tension and elasticity, that is, good cushioning property. As the futon cotton to be used in such a futon, cotton or wool, which has good fiber entanglement and elasticity, and also has good air-retaining property and hence heat-retaining property, is generally used.

[Problems to be solved by the device]

However, it is well known that the cotton and hair obtained by needle punching with a general cotton shaving machine and conventionally used are limited to short fibers having a length of 60 mm or less. In the case of a mattress containing a cotton blanket that retains air and is made bulky, the elasticity of the fibers of the portion directly receiving the weight against the body weight of the supine acts vertically, but the bond between the fibers of the mattress is Since it is a short distance compared to the dimension of the human body, as shown in the diagram in FIG. 3 showing the use situation, the comforter A is greatly depressed only in the portion where the weight of the supine person B is applied, and the body of the supine person B is depressed. Being constrained by the futon A, the futon becomes so-called too soft. In this state, there is a problem that sleep cannot be prevented from rolling over which leads to healthy sleep, and sometimes there is a built-in feeling of pressure, which rather hinders sleep. In addition, in such a use condition, the futon cotton in a portion where the weight is intensively applied has a problem that it is quickly fatigued and loses elasticity, so that cotton waving and other activation treatment are required at a relatively early stage.

Therefore, the object of the present invention is to provide a futon cotton which has moderate tension on the whole surface rather than a local area and is elastic, and therefore is easy to roll over, has a high sleep comfort and has a long durability. To do.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention proposes a futon cotton which is mixed with short fibers of 60 mm or less and long fibers of 200 mm or more and has lateral tension and elasticity.

[Action]

The futon cotton of the present invention receives weight locally from above,
A fiber network formed by the entanglement of long fibers extending in the lateral spreading direction on the surface of the futon exhibits lateral tension and elasticity, and supports the weight together with the vertical elasticity of the entangled long and short fibers themselves.

Short fibers are those with a length of 60 mm or less that can be obtained with an ordinary cotton shaving machine. As long fibers that are mixed with this, if they are long enough considering the dimensions of the human body, they can be used as futon cotton. Although it is expected to have the effect of providing lateral tension and elasticity, the effect has been confirmed especially for fibers of 200 mm or more.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 (a) is a diagram showing short fibers, FIG. 1 (b) is a diagram showing long fibers, FIG. 1 (c) is a diagram illustrating a blended cotton with both fibers, and FIG. FIG. 2 is a side sectional view of a mattress of the present invention, which shows the situation, and is a futon.

The short fibers 1 having an average length of 50 to 60 mm shown in FIG. 1 (a) and the long fibers 2 having an average length of 200 to 250 mm shown in FIG. Air-blend into the equipped cotton blender to fabricate a rather futon made of cotton blend 3 as shown in Fig. 1 (c), and then fold and fold it to produce a mattress with a thickness of approximately 100 mm. did.

As shown in FIG. 2, the mattress 4 is dented according to how the weight of the supine person 5 is applied, but the surface of the duvet 4 is soft and there is tension, and there is no depression that presses the internal organs. I was able to roll over.

A large number of people tried this mattress 4 and a conventional mattress manufactured to the same thickness with the short fibers 1 as shown in FIG. 1 (a). Regarding No. 4, with respect to the total number of times, it was obtained that 100% of the people had a good night's sleep, compared with about 50% in the case of the conventional mattress.

In the above, the case where the present invention is applied to a mattress has been described as a preferred embodiment, but the futon cotton of the present invention is not limited to this, and there are many application examples such as a cushion, a cushion sheet for chairs, and a pillow.

[Effect of device]

As is clear from the above description, according to the present invention, a suitable degree is obtained from the synergistic effect of the lateral tension and elasticity by the fiber net formed by the entanglement of long fibers and the vertical elasticity by the entanglement of long and short fibers. Softness, moderate tension, moderate elasticity and good cushioning, especially when applied to a mattress, the weight-bearing part does not fall locally, and the supine person compresses the internal organs. You can get a futon that keeps your body shape and is easy to roll over, so it is healthy and has a good night's sleep. In addition, since the fiber net suppresses local deformation of the fiber directly due to the weight, the effect of improving the durability of the futon cotton can be obtained.
