Description

CARPET AND MANUFACTURING METHOD THEREOF [0002]

More particularly, the present invention relates to a carpet having a multi-layered structure including a low density fiber fabric, which has excellent interlayer adhesion and a simple process, and a method for producing the same.

Generally, the production of a multi-layer structure of a low-density fiber fabric product is performed by a method of laminating a fabric in the form of a sheet type film, followed by laminating and adhering to various processes.

Since the conventional multi-layer structure manufacturing method of fabricating and laminating a fabric as described above is applied to a fabric in the form of a sheet or a paint, there is a problem that a coating liquid or an adhesive is permeated to the upper layer in the case of a low density fabric.

In addition, in the case of interior products such as carpets, wallpaper, flooring materials, and table fabrics, which are manufactured by such a method, the adhesive process must be performed a number of times, so that the price is high and the product is difficult to become a popular product.

In addition, conventional interior products such as carpets having a multi-layered structure using a low-density fabric have a problem in that adhesion and attachment performance between layers are weak, such as separation when a folded portion occurs during use and storage.

2 is a front view showing an apparatus for carrying out the method of manufacturing a carpet according to the present invention, and Fig. 3 is a front view showing the apparatus for carrying out the carpet manufacturing method of the present invention Fig.

The carpet of the present invention has a multi-layer structure as shown in Fig. 1 and comprises an upper layer 1, an middle layer 2 and a lower layer 3. [

First, the carpet is provided with an upper layer 1 which is exposed to the outside.

The upper layer 1 is composed of a fiber member, specifically a low density fiber member. Preferably, the low-density fiber member is composed of at least one of a para-aramid fiber, a polyester fiber, a carbon fiber, a nylon fiber, a polyester fiber, a vinyl fiber, a polypropylene fiber and a rayon fiber.

The outer shape of the upper layer (1) fiber can be variously changed according to the user, and it may include a beautiful pattern because it corresponds to the outer exposed portion of the carpet. In addition, depending on the type of fiber, a soft texture or the like can be imparted to the carpet.

Next, at the lower end of the upper layer 1, an intermediate layer 2 is provided as shown in FIG.

The middle layer portion 2 is provided with a foam layer and comprises a polyvinyl chloride (PVC) resin and a foaming agent to constitute the foam layer.

Further, at least one of a plasticizer, a stabilizer, a flame retardant, an antibacterial agent, and a filler is further added as an additive, thereby adding functionality to the carpet.

The middle layer portion 2 includes a foam layer, thereby lowering the weight of the product and providing a cushioning feeling.

Next, a lower layer portion 3 is provided at the lower end of the middle layer portion 2 as shown in FIG.

The lower layer portion 3 is formed of a flexible layer including a resin layer and a polyvinyl chloride sol (PVC sol) including a resin, a plasticizer, a stabilizer, and a flame retardant.

The lower layer portion 3 is located at the lowest end of the carpet, protects the foam layer of the middle layer portion 2, and has a packing layer, so that the user can use the carpet more conveniently.

In addition, the lower layer portion 3 can be provided with various functionalities to the carpet by using a functional resin such as flame retardant and waterproof.

Hereinafter, a carpet manufacturing method for manufacturing the carpet of the present invention will be described in detail with reference to the drawings.

First, a fiber member is fed in the first step. Specifically, the fiber member, which is the raw material of the upper layer portion 1 of the carpet of the present invention, is fed through the raw material feeding portion 4.

Next, in the second step, the resin materials of the intermediate layer and the lower layer having different viscosities are supplied by using the respective supply parts, and after the flat plate work is performed using the knife 5, layer separation occurs. Specifically, after a resin having a relatively high viscosity serving as a raw material for the lower layer portion 3 of the carpet is fed, a flat plate work is performed through a knife 5 operation, and then the viscosity of the middle layer portion 2 as a raw material is relatively low The resin is fed and the upper part of the lower layer part 3 is flattened by a knife 5 operation. Thereafter, due to the difference in viscosity between the middle layer portion 2 and the lower layer portion 3, the layer is separated and stably separated.

It is preferable that the viscosity difference of the resin as the raw material of the intermediate layer portion 2 and the lower layer portion 3 is 8000 cp to 8500 cp for the middle layer portion 2 and 10000 to 10500 cp for the lower layer portion 3 for stabilized layer separation.

When the difference in viscosity between the middle layer portion 2 and the lower layer portion 3 resin is less than 1500 cp, the layer separation can not be stably performed and the middle layer portion 2 and the lower layer portion 3 are mixed in the heating chamber, If the viscosity difference exceeds 2000 cp, the foaming cells of the middle layer portion 2 can not be formed uniformly at the foaming temperature, and the low density fabric of the upper layer portion 1 and the low- The adhesion may not be uniform or the resin of the middle layer portion 2 may be mixed on the upper layer portion 1 to be cured.

In addition, the resin viscosity of the intermediate layer portion 2 and the lower layer portion 3 should be adjusted within the above-mentioned ranges, which is preferable for carrying out processes such as supply, flat work, heating, and adhesion.

Next, in the third step, raw materials of the middle layer portion 2 and the lower layer portion 3 in which the layer separation has occurred are inserted into the primary chamber 6 and preliminarily cured. Specifically, the middle layer portion 2 and the lower layer portion 3, in which the layer separation has occurred, are inserted into the primary chamber 6 and pre-cured by heating to gel.

In the primary chamber 6, the resins of the middle layer portion 2 and the lower layer portion 3 are heated, and the heating temperature is preferably 145 to 150 ° C.

If the temperature of the primary chamber 6 is less than 145 ° C, the pre-curing and gelation may not be sufficiently performed. If the temperature exceeds 150 ° C, the middle layer portion 2 resin It is preferable to perform the heating in the temperature range.

Next, in the fourth step, the fiber member is inserted into the secondary chamber 7 and preheated. Specifically, the fiber material, which is the raw material of the upper layer portion 1, is inserted into the secondary chamber 7 and preliminarily heated so that the adhesive strength is better than that in the case of joining.

The temperature of the secondary chamber 7 is preferably 80 to 150 ° C.

If the temperature of the secondary chamber 7 is less than 80 ° C, the preheating effect of the raw fabric is deteriorated. If the temperature is more than 150 ° C, it may cause defects such as melting of the fabric, Do.

The temperature of the secondary chamber 7 can be varied depending on the material within the above-mentioned temperature range.

Next, in the fifth step, the pre-cured middle layer portion 2 and the lower layer portion 3 raw material and the preheated fibrous material are lapped using a ply roll 9 and then heated to the tertiary chamber 8 . Specifically, the raw materials of the intermediate layer portion 2 and the lower layer portion 3 subjected to the preliminary curing and the preliminarily heated fiber members are subjected to preliminary curing by using the lamination roll 9 to form the upper layer 1, the middle layer 2, (3) and then heated using a tertiary chamber (8).

By performing the heating through the tertiary chamber 8, the complete curing of the resins takes place to form the product, and the foaming of the middle layer portion 2 is achieved.

The temperature of the tertiary chamber 8 is preferably 150 to 165 ° C.

If the temperature of the tertiary chamber 8 is less than 150 ° C, foaming does not occur completely, and the effect of cushioning or weight reduction of the middle layer portion 2 may not be sufficient. If it exceeds 165 ° C, Or the efficiency of the operation is lowered.

Next, in a sixth step, the multi-layer fabric passing through the tertiary chamber 8 is cooled using the cooling plate 10. Specifically, the multi-layer fabric provided in the form of a product after being fully cured through the tertiary chamber 8 is cooled using the cooling plate 10 to provide a final product shape.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, All changes or modifications that come within the scope of the equivalent concept are to be construed as being included within the scope of the present invention.
