Specifically, in a planar heating element represented by an electric carpet, the carpet and the planar heating element are integrally and independently manufactured, and are used by being combined and used at the time of use. The present invention relates to a non-woven sheet for a surface material of a planar heating element.

Description of the Related Art Recently, as a planar heating element for an electric carpet or the like, a carpet and a planar heating element are manufactured independently and used in combination when used. For this reason, it has been demanded that the sheet heating element be heat-transferable to the carpet to be laid over it and not bulky and have a good storability.

As disclosed in the invention of 04614, after a heating wire is attached to a sheet material to form a sheet heating element, a carpet cloth (hereinafter referred to as a surface material) is attached to the surface of the sheet heating element, Then, the back surface is made of a heat insulating material such as felt or urethane. Needle punch carpets, needle felts and the like are used as general carpet materials for such surface materials because the heating wires are not exposed and the texture is good.

ってきた。However, in recent years, electric carpets often have a carpet cover overlaid on the upper surface of the electric carpet, so that the electric carpet has a heat insulating property because it is warmed on the surface of the electric carpet. Since the warmth is taken through the thick carpet cover, more heat of the electric carpet is transferred to the carpet cover, so the temperature of the electric carpet itself is raised, or the skin of the electric carpet is thinned, Measures such as conducting heat to the carpet cover have become necessary.

が必要となる。However, it is impossible to raise the temperature of the electric carpet itself higher than the conventional heat resistance allowable temperature of the insulation of the heating wire, and a method for thinning the skin of the electric carpet will be examined. That is a good idea. For that purpose, the skin of the electric carpet must be strong. On the other hand, if the skin is thin, there is a problem that the electric carpet is displaced or bent.

There was a problem of this.

It is a non-woven sheet for a surface material of a planar heating element, which is formed by fluffing a long fiber non-woven sheet having a heat-compression area ratio of 3 to 30%. The non-woven sheet for a surface material of a sheet heating element of the present invention is a long-fiber non-woven sheet having a thermocompression bonding portion represented by spunbond, and is a fiber represented by (ρ ′ / ρ) × 100. Filling ratio (%) (ρ 'is the apparent density of the fiber structure, ρ
Is the true density of the fiber), preferably 9 to 30%, preferably 10 to 2
Those with 5% are good. When the fiber filling rate is less than 9%, the fiber gap of the non-woven sheet becomes large, so that dust enters. If the fiber filling rate exceeds 30%, the non-woven sheet is not suitable because the fiber gaps are small and dense and hard. (A '/ A) x
The thermocompression bonding area ratio (%) represented by 100 (A 'is the area of the thermocompression bonding portion, A is the area of the non-woven sheet) is 3 to 30%, preferably 5 to 20%. Thermocompression bonding area ratio is 3
If it is less than%, the constituent fibers of the non-woven sheet become loose and the strength is low, and troubles occur during fluffing. If the thermocompression bonding area ratio exceeds 30%, the nonwoven sheet becomes hard, which is not suitable. Examples of the long-fiber non-woven sheet include polyester fibers such as polyethylene terephthalate, polyamide fibers such as nylon 6 and nylon 66, polyolefin fibers such as polypropylene, and two-component fibers such as polyethylene / polyester sheath core, and the like. A long-fiber non-woven sheet made of mixed fibers or composites. A long-fiber polyester non-woven sheet is preferable. The basis weight of the long fiber non-woven sheet is 50 to 400 g / m 2, preferably 70 to 200 g / m 2 .

がこの限りでない。Then, the non-woven sheet is subjected to fluff stopping processing so that it becomes suitable for the surface material of the sheet heating element. The fluff stopping process here is a process of applying an acrylic, urethane, rubber or other resin binder by a processing method such as a padding method or a coating method to stop the fluff, and the amount of adhesion is 5 to 5. 20% is preferable,
Beyond that, it becomes stiff and difficult to fold.
The level of fluffing needs to be maintained at 500 times or more of the Taber abrasion test shown in JIS L-1021. Further, when the surface material loses the required flexibility due to the fluff stopping process, the surface process may be performed as necessary. Examples of the softening process include, but are not limited to, a jet dyeing machine, a water jetting process such as a washer, and a water jetting process such as a columnar flow process.

It has excellent thermal conductivity, is easy to fold, and has excellent storability, and it is easy to clean without dust entering the surface fibers. Furthermore, during the manufacturing process of the sheet heating element, the processing time for thermally bonding the surface material and the heating wire can be shortened.
