JPS5940505Y2 - Tatami floor - Google Patents

Description

[Detailed explanation of the invention] Tatami with a straw layer is hygroscopic and breathable, and has been used as a flooring material suitable for the climate of Japan since ancient times, but the straw layer deteriorates in a relatively short period of time and becomes elastic. In addition to this, recent changes in agricultural practices have made collecting rice straw difficult.

In view of these shortcomings of the straw layer, this product uses a combination of a palm fiber layer and straw, which maintains the same hardness and elasticity as Shinjo without changing the feeling of pressure even after long-term use, and is durable. It is also economically advantageous.

To explain an example below, a layer 4 of straw arranged in almost the same way as a conventional straw layer is layered on the upper surface or both upper and lower surfaces of a palm fiber layered body 1, and this is applied using a known tatami machine or the like. It is formed on the tatami floor 3 by appropriate compression stitching.

The palm fibers that make up the above palm fiber layer are made by soaking the skin of coconut palms in water to make them sour, and then separating the fibers contained therein by machine or hand.The length of the fibers is approximately 10-3
It has a fiber thickness of approximately 0.1 to 0.6 rran, is rigid and elastic, and has strong corrosion resistance against water.

The fibers are either collected as they are, or strongly twisted to form a fluff, then unraveled and crimped, and then arranged regularly or irregularly to form the fiber layered body of a desired thickness. Alternatively, the fiber layered body having the required thickness can be formed by layering a plurality of thinly formed fiber layered bodies.

In addition to the above, the fibrous layered material may be formed with pricking needles at appropriate intervals, for example, at a needle pitch of about 0.3 to 20 m, to the required thickness for piercing and extraction, or a fibrous layered material formed thinly as described above. The fibrous layered body is coated with rubber, synthetic rubber-containing latex, synthetic resin adhesive, etc. to suitably cover the fiber surface, and the fibers are intersected. It is also possible to use a material in which the parts are appropriately bound.

When a medicinal layer is superimposed on the needles or glued together in this way and compression stitching is performed, it is easy to handle, the fibers do not fall off, and the bond between the fibers is better. This results in a product with even better pressure feel and durability.

In Figure 1, as-collected palm fibers are arranged irregularly and lrr? Five layers of pierced palm fibers with a thickness of about 17rIWrL (fiber amount of about 2Kg/rr?), which are pierced at a rate of about 13,300 needles per needle, are stacked on top of each other, and on top of that, coconut fibers of the required thickness are arranged in the same way as conventional condiments. The medicinal layers are overlapped, passed through a known tatami machine, and sewn with synthetic fiber tatami yarn to reduce the area between the warp and weft to 12 cd or less.A medicinal layer of approximately 25 m is placed on the top surface of the approximately 25 at palm fiber layer 1. The tatami floor forming 5 is shown.

Although this tatami bed is a little heavier than the conventional straw layer, the tatami mat with the tatami omote retains the same texture as a new condiment even after long-term use, and in this case, the same effect can be obtained even if the medicinal layer is relatively thin. This reduces the amount of straw consumed and eliminates the difficulty of collecting the straw.

The palm fiber layer is made of thick, rigid, and elastic fibers that do not deteriorate even after long-term use, and there are large gaps between the fibers to form a whole atmosphere, and it is also strong. This strengthens the support of the straw waste, so it does not become locally soft or deliquesce like traditional straw layers, and maintains appropriate breathability, making it easy to adjust humidity, making it always comfortable. Provides a comfortable feeling of use and living space.

FIG.
Approximately 20 to 30 trr formed by stacking 6 sheets and stacking straw waste arranged in the same manner as above on both upper and lower surfaces.
A tatami floor is shown having about 15 to 10 m of straw waste 5 on both the upper and lower surfaces of a m-thick coconut fiber layer 1.

This tatami floor also provides excellent tatami mats similar to those described above.

The upper surface or upper and lower surfaces of each tatami floor are covered with nonwoven fabric 6, strong paper, fabric, etc., and especially the lower surface is covered with polyolefin or other synthetic resin film, or paper laminated with a thin film of these synthetic resins, as described above. It is also possible to form a sewn tatami floor, and the top surface of the tatami floor is smoothed to better blend in with the tatami surface.
It also strengthens the lower surface and prevents moisture from entering from under the floor.

The thickness of the above-mentioned fiber layered body, the number of layers thereof, the fiber weight per unit area, the thickness of straw waste, the thickness of the manufactured tatami floor, the spacing and degree of compression of sewing threads, the weight per unit area, etc. can be changed as appropriate. .
