カーペットに間する。For more information, see ``Hot Water Floor Heating'', which installs pipes on the floor and flows hot water through it, ``Electric Floor Heating'', which installs an electric heater on the floor, and ``Electric Floor Heating'', which installs ducts on the floor to blow hot air into it. Tufted carpets are used as a floor surface finishing material for recessed and panel type heating facilities that heat the floor surface using the radiant effect, such as hot-air floor heating.

障をきたしていた。Jute pack toughtit carpets were mainly used, but these generally lacked cushioning properties, so felt was placed between the carpet and the heater in order to provide a good walking feel during use. Construction was generally carried out using an insole and gripper method. However, the felt used for the insole has poor thermal conductivity and high thermal resistance, making it unsuitable for comfortable floor heating, and the initially good walking feeling that can be obtained is limited by the poor recovery of strain caused by felt compression. As use progressed -) you tended to get worse. The looseness of the felt not only affected the feeling of walking, but also affected the conductivity of heat, making it difficult to operate the floor heating system stably.

反応性に乏しい気体を用いると良好な結果が得られる。The present inventors solved the drawbacks of conventional carpets, and as a result of intensive study on the performance required of the above-mentioned floor heating carpets, they arrived at the present invention, which is made of polyester fabric. Base fabric or non-woven primary base fabric with pile length of 10 mm or less, pile density of 0.03 to 0.30 g
A mechanical floss urethane foam obtained by mechanically dispersing gas in a mixture whose main components are polyisocyanate and polyether polyol or polyester polyol is applied to a carpet base material flocked with piles made of synthetic fibers or natural fibers. This carpet for floor heating is characterized by being lined with a foam thickness of 2 to 8 times and 2 to LOmm to lower the thermal resistance value of the entire carpet. Good results can be obtained by using a gas with poor reactivity, such as air or an inert gas, as the gas used here.

関しては１００〜３００ｇ／ｄが好ましく、１２０〜２
００ｇ／イてあればなお良い。The primary base fabric polyester woven base fabric or non-woven fabric used here is important as it provides thermal dimensional stability to the entire carpet, and polypropylene material, which is commonly used for carpets, has been used as the primary base fabric. When used, it interferes with thermal dimensional stability, and specifically causes gaps due to expansion and contraction of the carpet and blistering of the carpet when using floor heating, which impairs the appearance and poses a major problem in use. In addition, the basis weight of the second base fabric is preferably 100 to 300 g/d, and 120 to 2
It would be even better if it was 00g/y.

工時の床面へのフィツト性等に問題が生ずる。If the basis weight is less than 100 g/&, the effect of the primary base fabric as reinforcement for the heating stability of the carpet will be impaired, and the mechanical strength of the carpet, that is, the tensile strength and tear strength, will be reduced, and the durability during use will be reduced. In addition, if the basis weight of the base fabric is 300 g/ln' or more, the tufting properties during flocking will be poor, making efficient production difficult, and the carpet will also be stiff and have poor texture. It hardens and causes problems in fitting the carpet to the floor surface when installing it.

ループ、レヘルカット等の選択が可能である。For example, as the pile material, synthetic fibers or natural fibers such as polyester, nylon, wool, cotton, linen, etc. can be used. However, since it is used for floor heating, it is preferable to use one with excellent heat resistance. In addition, in the pile form, it is possible to select from lehel loop, multilehle loop, cut-and-loop, lehle cut, etc.

g/♂preferably 0.05-0, 15 g/cTn
Is it necessary to do so? The pile density in this case is the value obtained by dividing the pile basis weight shown on the first side of the table, which is the area above the primary base fabric of the carpet base, by the product of the pile length and the area.

Moreover, if it is 0.30 g/am or more, it will be good in terms of thermal conductivity, but it will be difficult to implant hair.

り問題が生ずる。The urethane foam used in the present invention includes polyether polyols, polyester polyols, that is, diols such as ethylene glycol and propylene glycol, triols such as glycerin, etc., and the isocyanates include tolylene diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, etc. is used. If necessary, other additives such as fillers,
Catalysts, foam stabilizers, colorants, anti-aging agents, flame retardants, etc. are used. Further, the expansion ratio of the mechanical froth urethane foam for the backing material is 2 to 8 times, preferably 3 to 5 times, and the foam thickness is preferably 2 to 10 mm or 3 to 5 mm. When the expansion ratio is less than 2 times, it is difficult to obtain good urethane properties, and when it is more than 8 times, the thermal resistance value becomes large, the compressive strength decreases, and a feeling of bottoming out occurs. From the same point of view, if the foam thickness is 2 mm or less, the cushioning properties will deteriorate, and if it is 10 mm or more, the thermal resistance value will increase, causing problems.

０°Ｃ前後の快適な床暖房を得るためである。In the first place, mechanical floss urethane foam, which is used as a backing material for carpets, provides cushioning properties and mechanical strength to the carpet, and is effective in realizing simple installation, as well as adjusting the thermal resistance value of the entire carpet. It is important as a thing. Carpet as a floor surface finishing material for floor heating must have a thermal resistance value within an appropriate range, and this is necessary to maintain a comfortable living environment for occupants in a heating system that takes into account the radiant heat of floor heating equipment. In order to achieve this, it is preferable that the surface temperature of the floor surface finishing material be around 30°C. Considering the durability and safety of floor heating heaters, there is a limit to the temperature setting of the heater, so carpets with low thermal resistance values are used. By providing good heat conduction, the carpet surface temperature can be reduced by 3.
This is to obtain comfortable floor heating at around 0°C.

く厚みの選定が広範囲に可能となる。While mechanical floss urethane foam has excellent strength, durability, and cushioning properties, it also mechanically disperses gas to form floss during processing, so the foaming ratio can be easily controlled by fine-tuning the machine. Furthermore, since it is a reactive thermosetting material, there is a significant decrease in workability when the foam thickness is increased, which is seen in water-based products such as SBR rubber foam, which is commonly used for foam hacking, and hardening. The thickness can be selected from a wide range without creating an uncured layer within the foam due to water volatilization problems.

が可能となる。This means that even if the thermal resistance value of the carpet base material changes due to its form, etc., by adjusting the foaming ratio and thickness of the mechanical foam urethane foam that is the backing material, the overall thermal resistance value can be adjusted within the desired value. allow it to be contained within. In addition, as for the physical properties of the foam, it is possible to maintain stable physical properties and quality with less deterioration due to heat, which is seen in SBR rubber foam, and softening at high temperatures, which is seen in thermoplastic resin foams such as PE ohm and PVC foam.
