[Problems to be solved by the invention]
As indicated by the above-mentioned patent documents, functional agents such as deodorant, antibacterial, fungicide, insect repellent, and mite-proof are applied to a carpet by being applied to any of a pile, a primary backing, and a backing resin. However, when a functional agent is applied to a pile, not only is the color and texture of the pile impaired, but it is difficult to determine that the pile is completely harmless even though it is harmless. When a functional agent is applied to the primary backing, even if it does not cause a decrease in the physical properties of the primary backing, the primary backing vibrates violently by being rubbed by needles or pile yarns in the tufting process, and the functional agent is removed. It is easy to fall off from the primary base cloth, which adheres to needles, loopers, knives, etc., and causes corrosion of the tufted machine. When blending a functional drug into a backing resin composition, the physical quality and storage stability of the backing resin composition are impaired, and the functional drug itself is hardly wrapped in the backing resin composition and exerts its function. When the amount of the backing resin composition is increased, the physical properties and storage stability of the backing resin composition are greatly impaired, and the cost is increased.
[0005]
[Object of the invention]
Therefore, an object of the present invention is to efficiently and economically apply a functional drug to a tile carpet.
[0006]
[Means for Solving the Problems]
The tile carpet according to the present invention has a function in which a functional drug component is dissolved in a back stitch 14 of a pile yarn interposed on the back surface of a tufted pile fabric 13 in which a pile yarn is inserted by inserting a pile yarn into a primary base cloth 11. The first feature is that a treatment liquid is impregnated, and a moisture-impermeable backing layer 15 is laminated on the back surface of the tufted pile fabric 13 with the back stitch 14 interposed therebetween.
[0007]
A second feature of the tile carpet according to the present invention is that, in addition to the first feature, the primary base fabric 11 is a polyester long fiber spunbond nonwoven fabric having a basis weight of 80 to 120 g / m ² .
[0008]
A third feature of the tile carpet according to the present invention resides in that at least one of zinc oxide and zinc sulfate is applied to the functional drug component in addition to any one of the first and second features. .
[0009]
A fourth feature of the tile carpet according to the present invention is that, in addition to any one of the first and second features, the functional drug component contains at least one of zinc oxide and zinc sulfate, ferrous sulfate, and sulfuric acid. Magnesium, sodium sulfate and disodium ethylenediacin tetraacetate are applied as essential components.
[0010]
A fifth feature of the tile carpet according to the present invention is that, in addition to any one of the above first, second, third and fourth features, the backing layer 15 is composed of a vinyl chloride paste resin as a resin component. It is in the point.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, the functional drug means a chemical substance having any of deodorant, antibacterial, antifungal, insect repellent and mite-preventing functions, and includes the above-mentioned known functional drugs shown in the prior art. It is. In the present invention, a chemical substance having a deodorant function, a chemical substance having an antibacterial function, a chemical substance having an antifungal function, a chemical substance having an insect repellent function, and a chemical substance having an anti-mite function are referred to as “functional drugs”. Collectively, most of the known functional agents having a deodorizing function at the same time have antibacterial, antifungal, insect repellent, or antimite functions, and many of those having an antibacterial function simultaneously. Any of deodorant, antibacterial, antifungal, antifungal, anti-mite, etc. Nothing has one function, and in many cases, it has all the functions of deodorant, antibacterial, fungicide, insect repellent, and mite. Can be specified as exhibiting any one of the functions According to it.
[0012]
Preferred functional agents are those which can be prepared as an aqueous solution, and are preferably prepared using zinc oxide or zinc sulfate as an essential component. Since zinc oxide itself is insoluble in water, zinc oxide is dissolved in an acidic aqueous solution, an alkaline aqueous solution or an aqueous ammonia solution, preferably an aqueous ammonia solution, or zinc oxide is fine particles having a particle size of nanomicron (nμ) units, Fine particles having a particle size of 1 micron (1 μm) or less are used. As a functional drug, zinc oxide, ferrous sulfate, magnesium sulfate, sodium sulfate, and those containing disodium ethylenediacin tetraacetate as the main components are called “Efnica PM-W” from Nangang Efnica Co., Ltd. It is known under the name of the product, and as a result of practical tests, it is recommended in view of the durability of the deodorant effect, and its use is recommended.
[0013]
In the present invention, applying the functional agent to the backstitch 14 as an aqueous solution does not cause inconveniences such as falling off during the tufting process or corroding the tufted machine, and also reduces the pile on the tile carpet surface. It does not impair the appearance and texture and the physical properties of the backing resin composition, and because the back stitch 14 has a porous structure of fine fibers of 20 dtex or less, it easily absorbs and retains the functional agent. In addition, since the fibers of the back stitch 14 penetrate the primary base cloth 11 and continue to the base 16 of the pile, the functional agent and the outside air can easily come into contact with each other. Because it is a very limited part called the root 16 of the pile that penetrates through, the effect of sustained release of the components occurs and the functionality is maintained.
[0014]
A penetrating agent may be blended in the functional processing liquid, but the blending of the binder resin is to be avoided as much as possible because it hinders the penetration of the functional processing liquid into the back stitch interior 14. However, depending on the tufted pile fabric, the functional treatment liquid may be easily absorbed and may easily spread to the pile surface. In such a case, an aqueous solution resin such as polyvinyl alcohol, methylcellulose, and carboxylmethylcellulose is added to the functional processing solution not as a binder but as a viscosity modifier to suppress the permeability. Even in such a case, the amount of the resin adsorbed is adjusted depending on the concentration of the functional processing solution and the method of application, in order to minimize the amount of the resin component. The component concentration of the functional processing solution is 10 to 40%, the amount of the functional processing solution applied to the back stitch 14 is 50 to 150 gf / m ^2, and the amount of the functional agent (pure component) adsorbed on the back stitch 14 Should be generally 10 to 50 gf / m ² .
[0015]
The reason why the backing layer 15 is made to be impermeable to moisture is that a functional agent is applied without using a binder, and the functional agent is transferred to the back of the tile carpet 17 due to moisture touched during use, or the tile carpet is used during use. The function of the functional agent is not hindered by moisture or odor generated from the construction base (floor surface) of No. 17, so that the function can be effectively operated with respect to the outside air on the front side (indoor) of the tile carpet 17. That's why.
[0016]
The backing layer 15 is formed by bonding a moisture-impermeable film to the back surface of the tufted pile fabric via a heat-fusible resin, or extruding a hot-melt heat-fusible resin composition from a T-die extruder, or In addition, lamination is performed by applying a vinyl chloride paste using an application device. The functional treatment liquid may be applied to the back stitch surface 14 by a roll coater or a spray immediately before the coating and laminating step of the backing layer 15, and may be completely dried and generated in the heating zone in the coating and laminating step of the backing layer 15.
[0017]
Either a woven base fabric (woven fabric) or a nonwoven fabric is used for the primary base fabric 11, but in the woven base fabric (woven fabric), the warp or weft constituting the woven base fabric is formed by a needle inserted in a tufting process. The gap between the warps and the wefts that compose the woven fabric is created according to the thickness of the pile yarn that is planted there and penetrates, and between the warps and the wefts. The functional treatment liquid easily oozes out on the pile surface through the gap. Therefore, a nonwoven fabric having no gap around the root 16 of the piled pile, particularly a continuous filament fiber web (sedimentary layer) is heated and pressed on the primary base fabric to form a spun fiber between the fibers. It is preferable to use a bonded nonwoven fabric, more preferably a spunbonded nonwoven fabric made of a polyester-based composite continuous fiber having a core-sheath structure in which a high-melting polymer is a core (island) component and a low-melting polymer is a sheath (sea) component. The basis weight is preferably set to 80 to 120 gf / m ^{2 from} the viewpoint of preventing the liquid from exuding to the pile surface and the effect of sustained release of the functional component.
[0018]
【The invention's effect】
According to the present invention, the functional agent does not intervene in the pile layer 12 or the backing layer 15 but intervenes in the primary fabric 11 and the back stitch 14 sandwiched between the backing layer 15. The functional tile carpet equivalent to a normal product can be obtained by a conventional method without impairing any quality characteristics of the appearance and physical properties of No. 15.
[0019]
The back stitch 14 has a porous structure made of fine fibers of 20 dtex or less, and a functional agent is prepared in an aqueous solution and applied to the back stitch 14 forming the porous structure, and the inside of the back stitch is finely divided. It is uniformly dispersed and adheres to form a film on the fiber surface inside the back stitch. On the other hand, since the backing layer to be subsequently laminated is made of a high-viscosity resin composition, the backing layer does not penetrate into the inside of the back stitch 14, so that the functional agent is not wrapped in the resin composition of the backing layer. Then, since the fibers of the back stitch 14 are continuous with the base 16 of the pile through the primary base cloth 11, the functional agent finely and uniformly dispersed inside the back stitch is transferred to the base 16 of the pile. It is easy for the outside air to come in contact with the fiber through the continuous fiber, and the portion where the outside air touches is a very limited part called the root 16 of the pile penetrating the primary base cloth 11, so that the effect of sustained release of the functional drug occurs. , Its functionality lasts.
[0020]
Even if the functional agent is applied to the fibers of the backstitch 14 without using a binder, it is blocked by the moisture-impermeable backing layer 15, so that it may migrate to the back of the tile carpet 17 during use. The function of the functional agent is not hindered by moisture and odor generated from the construction base (floor surface) of the tile carpet 17 during use. Run effectively.
[0021]
Thus, according to the present invention, a tile carpet which is excellent in deodorant, antibacterial, antifungal, insect repellent, and anti-mite properties, and whose physical properties other than that of a normal product can be economically produced by a small amount of a functional agent. Can be obtained.
