Printing method of flocking fabric and flcokng carpet comprising flocking fabric

The present invention relates to a method of printing a flocking fabric and a flocking carpet, and more particularly, it is possible to implement various designs, including the steps of printing the flocking fabric with a rotary screen printer and washing after printing. The present invention relates to a method of printing a flocking fabric that provides excellent friction fastness, and does not cause fading, wrinkle formation, or frictional fluffing, and a flocking carpet including a printed flocking fabric.

Carpet has been used for indoor flooring for a long time. When the pile layer of the carpet is vertical or woven, the fibers constituting the carpet layer are looped or inclined upright. The density of the fibers is not high and there is a space between the fibers, such a carpet has a problem that is not beneficial to the human body to provide a space for hiding dust or ticks. In order to solve this problem, Flocking Carpet has appeared, and Flocking Carpet has a flocking method of vertically cutting pile yarns using static electricity to pile fibers of pile layers. It is composed of Flocking fabric, which is more than 10 times 80 million / m² high density structure. Due to the high density of the structure, the Flocking Carpet has a dense structure that prevents the penetration of contaminants, ticks, and bacteria, as well as cleaning the water, which solves the carpet's hygiene concerns. Its structure makes it easier to loosen all-new carpets like regular carpets, so you can always have new durability.

On the other hand, the flocking fabric has been commonly practiced to print using a dye in order to have a pattern having a predetermined color on the piled yarn. Printing refers to dyeing various types of patterns by partially printing on a surface of a to-be-tained object by mixing a favorable agent or synthetic resin with a dye or a pigment. That is, the printing method of the flocking fabric is a dyeing method in which the textile material is partially colored and stained so that a pattern appears, and the pattern printing is performed by stamping the printing paste containing dye in the textile material. Conventional methods of printing flocking fabrics generally consist of an edge (or printing), heating, washing and drying process. The printing (or printing) process is a process of pouring a dye or pigment on the printing zone and printing a pattern for each color. In the printing method of the conventional flocking fabric, the printing (or printing) process is mainly performed by using a roller printer. A rubber roller printer is a device for printing a pattern on a fabric by giving an intaglio or emboss to a rubber roll. There is a design limitation that can not be printed. The steaming process is a steam steaming process for fixing dyes or pigments coated on fabrics, which increases dyeing and fastness. Washing process is a process of washing printing fabrics, and removes unneeded undesired matter, dust, blemishes, etc. during printing. The drying process is a process in which a washed fabric is put into a drier and completely dried, and a flat and uniform process is also performed using a tenter. However, the printing method of the conventional flocking fabric mentioned above is difficult to implement a variety of designs, and due to the heat-fixed fixing immediately after the edge (or printing) process, the fixing of the dye or pigment is incomplete and the color in the subsequent washing process This fallout phenomenon (color fading phenomenon) occurs, there is a problem such as wrinkles occur in the printed final flocking fabric.

In order to solve this problem, a method of printing a flocking fabric has been proposed. The method of printing a flocking fabric has a limitation of design implementation by using a rubber roller printer. Omitting prevents color fading but causes wrinkles on printed flocking fabrics, and powders such as foils are blown out by friction. Commercial facilities, government offices, hospitals, infant facilities, welfare facilities There is a limit to use as a fabric of the flocking carpet used for the back, there is a problem that the friction fastness is lowered.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, detailed description is abbreviate | omitted when it is judged that it may obscure the summary of this invention. In addition, preferred embodiments of the present invention will be described below, but the technical idea of the present invention is not limited thereto, but may be implemented by those skilled in the art.

One aspect of the present invention relates to a printing method of the flocking fabric, Figure 1 is a flow chart showing the process of the printing method of the flocking fabric according to the present invention. As shown in Figure 1, the printing method of the flocking fabric according to the present invention supplying step of the flocking fabric (S10); Innal step (S20); Drying step (S30); Steaming step (S40); And washing / drying step (S50).

In the printing method of the flocking fabric according to the present invention, the supplying step of the flocking fabric (S10) is a step of supplying the flocking fabric, which is piled by the pile yarn by the flow processing, to the rotary screen printer. The flocking fabric is composed of a bubble layer and a pile layer formed by planting pile yarn on the upper surface of the bubble layer. The bubble layer may be made of a glass fiber fabric, but the glass fiber fabric may not have a high elongation, which may cause wrinkles after printing, and control of numerous process conditions is required to suppress wrinkles. Thus, the bubble layer of the flocking fabric is preferably made of polyester nonwoven or polypropylene nonwoven. The pile yarn may be selected from the group consisting of nylon fibers, polyethylene fibers, rayon fibers, and mixed fibers thereof. In addition, the pile yarn is planted at an angle with respect to the top surface of the bubble layer and is inclined, and is preferably planted perpendicularly to the top surface of the bubble layer.

In the printing method of the flocking fabric according to the present invention, the printing step (S20) is a step of printing the color composition with a rotary screen printer (Rotary Screen Printer) to have a predetermined pattern on the surface of the flocking fabric. At this time, it is preferable that it is 2-8 m / min, and, as for the edge speed of the flocking fabric by a rotary screen printer, it is more preferable that it is 4-6 m / min. When the inking speed of the flocking fabric by the rotary screen printer is less than 2 m / min, the printing speed is too slow to reduce productivity, and when the inking speed of the flocking fabric by the rotary screen printer exceeds 8 m / min The composition may bleed to yield the desired pattern. Conventional rubber roller printers used in the inking stage of the flocking fabric is a device for printing a pattern on the fabric by engraving or embossing the rubber roll, which has a design limitation in that two or more colors cannot be printed, but is used in the present invention. Rotary screen printers can print patterns of 2 to 5 colors at a time, and can print patterns of up to 10 colors. In addition, when the coloring composition is inlaid on the surface of the flocking fabric using a rubber roller printer, the color fading phenomenon occurs by the subsequent washing process, but the inscription of the coloring composition on the surface of the flocking fabric using a rotary screen printer is used. In this case, the color fading does not occur even after the subsequent washing process.

Rotary screen printers used in the printing step of the printing method of the flocking fabric according to the present invention is not limited in kind and may be selected from those that are commercially available or commonly known. 2 is a view showing an example of a rotary screen printer device used in the printing method of the flocking fabric according to the present invention. As shown in FIG. 1, the rotary screen printer apparatus 100 according to an embodiment of the present invention includes a screen 20 and a humidifier 30. The screen 20 rotates in contact with the upper portion of the moving flocking fabric 10 and releases the coloring composition provided therein and prints the fabric 10. More specifically, the inside of the screen 20 is provided with a coloring composition filling rod (not shown) for discharging the coloring composition filled into the screen 20. However, as long as the coloring composition filling rod is not provided and the coloring composition can be discharged from the inside of the screen 20 to the outside, any screen can be used. That is, the coloring composition is discharged from the coloring composition filling rod to flow into the interior of the screen 20, the coloring composition flowing into the interior of the screen 20 is transmitted to the outside of the screen 20 to the coloring The composition is printed on the fabric 10. In addition, the outer surface of the screen 20 is formed with a design mesh 21 for printing the colored composition emitted from the inside to the fabric 10 in a predetermined design (or pattern). That is, the coloring composition is printed through the design mesh 21 to the fabric 10 in a constant design. In addition, the coloring composition may be a dye composition that is commonly used, or may be a pigment composition mixed with a pigment and a binder resin. When the coloring composition is a pigment composition, the pigment may be attached to the top of the fabric 10 by embossing, metal or hologram. In this case, the binder resin of the pigment composition has a constant viscosity and serves as a paste for attaching the pigment to the fabric 10, and has a property of being easily cured in air. That is, when the pigment composition is cured in the design mesh 21, the pigment composition inside the screen 20 may not penetrate to the outside, and thus, the fabric may not be printed. Therefore, the crosslinking agent which delays hardening of the said binder is preferably added to the said pigment composition. It should be noted that when the crosslinking agent is added to the pigment composition at a high ratio, the curing of the binder may be delayed, but the viscosity of the binder may be lowered so that the pigment does not adhere well to the fabric 10. Should be attached properly. The content of the crosslinking agent is about 0.5 to 3% by weight based on the total weight of the pigment composition, wherein the pigment adheres well to the fabric 10 while curing of the binder is appropriately delayed. The humidifier 30 is spaced apart from the screen 20 and sprays the humidifying gas a toward the screen 20. That is, the humidifier 30 maintains the surface of the screen 20 at a constant temperature and humidity to prevent hardening of the pigment composition emitted from the design mesh 21. In addition, the humidifier 30 is provided in parallel with the longitudinal direction of the screen 20, and includes a humidifying gas supply bar 31, the humidifying gas (a) is introduced into the inside. In addition, the humidifying gas supply bar 31 may be fixed to any part of the rotary screen printer device 100 if it can be fixed spaced apart parallel to the screen 20. In addition, a humidifying gas inlet 31a through which the humidifying gas (a) flows is formed at one end of the humidifying gas supply bar 31, and the humidifying gas (a) is formed on a surface of the humidifying gas supply bar 31. A plurality of humidifying gas discharge ports 31b are formed so that) may be evenly sprayed on the front surface of the screen 20. However, the humidifying gas discharge port 31b may be provided as one humidifying gas discharge port. In addition, the humidifier 30 may further include a humidifying gas generator 32 for generating the humidifying gas a and supplying the humidifying gas to the humidifying gas supply bar 31. In addition, the humidification gas generator 32 is a water tank (not shown) for storing water therein, an air unit (not shown) for vaporizing the water stored in the water tank and supplying the humidification gas supply bar 31. And a thermostat (not shown) for maintaining the water at a constant temperature. At this time, the water temperature is adjusted to about 60 ~ 70 ℃ by the temperature controller. In addition, the temperature controller may adjust the temperature of the water by receiving the ambient temperature of the screen 20 from a temperature sensor (not shown) for detecting the ambient temperature of the screen 20. In addition, the air unit may adjust the supply of the humidifying gas a by receiving the ambient temperature of the screen 20 from a humidity sensor (not shown) that detects the ambient humidity of the screen 20. In addition, a softening agent may be added to the water to prevent hardening of the pigment composition.

In addition, the coloring composition used in the innal step of the present invention may be a dye composition or a pigment composition. Printing is generally divided into the dye printing using a dye composition as a printing paste and the pigment printing using a pigment composition as a printing paste according to the kind of coloring composition. In the coloring composition according to the present invention, the dye composition includes a dye solution and a lake and the pigment composition includes a pigment and a lake. The dyes and pigments serve to impart color to the flocking fabric, and the lubricating agent (referred to as 糊劑, or paste) serves as an intermediate to dye the dye composition or pigment composition onto the flocking fabric.

When using the dye composition as the coloring composition according to the present invention, the dye composition preferably comprises 35 to 45% by weight of the dye solution and 55 to 65% by weight of the dye solution, based on the total weight of the dye composition. It is done. In this case, the dye solution is a dye is dissolved in water or oil at 80 ~ 100 ℃, the ratio of the dye and water can be made in various ratios according to the desired color and transparency. The temperature of the water is preferably about 80-100 ° C. in order to allow the dye to be uniformly and quickly dissolved in water. The dye is characterized in that an acid dye or a basic dye is used and is preferably an acid dye. Acid dyes generally have a higher color fastness than basic dyes. Acid dyes are generally referred to as water-soluble dyes having acidic groups, and are made from intermediates having acidic groups or sulfonated with fuming sulfuric acid. Azo, anthraquinone, triphenylmethane, xanthine dye, and the like are mainly azo dyes. The main use is dyeing of wool, and various uses such as leather, cellulose, lake pigments, inks, food colorings and indicators. In the dye composition according to the present invention, the (糊劑) accounts for about 55 to 65% by weight based on the total weight of the dye composition. When the content is less than 55% by weight, the dye is insufficient to dye on the flocking fabric, and thus printing cannot be performed properly. The effect is less economical without showing a distinct difference, and also the color clarity of the dye dye may be lowered. The type of inhibitors that can be used in the dye composition according to the present invention is not particularly limited, and for example, natural agents, semisynthetic agents, synthetic agents and the like can be used. have. Natural supplements include plant supplements such as starch, natural rubber, vegetable proteins, and seaweeds, animal supplements such as animal proteins, gelatin and glue, and mineral supplements such as bentonite. Iii). Semisynthetic agents include fibrin derivatives, processed starch, processed natural rubber, and the like. Synthetic agents include vinyl derivatives, acryl derivatives, synthetic rubbers, and the like. The vinyl derivatives include polyvinyl alcohol (PVA), modified PVA, polyvinyl acetate, polyvinyl butyral resin, polyvinyl acrylate resin, and acrylic derivatives such as polymethacryl, polyacrylamide, and synthetic rubber butadiene. and urethane. In addition, there are alkyd resin and urea system. Among these, acrylic derivatives are the most excellent among synthetic agents having different adhesive strength of the film, and the forming film has elasticity and flexibility. In the process, it is easy to prepare a preparation process. In addition, the dye composition according to the present invention may further include a leveling agent, an antifoaming agent, an antomic form, a degassing agent, a penetraion agent, a migration inhibitor, a fabric softener, or a wetting agent. have. For example, the gel may further contain the amount of 0.5% or 5% by weight of yuan or urea. The yuan improves solubility between the dye compositions to allow even dyeing. In addition, the urea acts as a wetting agent to increase the solubility of the dye composition and increase the moisture content in the flocking fabric upon heating, and to keep the dye composition in a very stable state for a long time. The necessary properties of the foam include physical performance, that is, fluidity, viscosity safety, heating safety, dilution resistance, catchment, and permeability. Chemical performances include compatibility with dyes or pigments and chemical resistance. , Bacterial resistance, reduction resistance, and the like. There are a lot of hobicides on the market, but their performances are different, and they have advantages and disadvantages, so a single hob cannot satisfy the characteristics required for printing. It is common to mix and use a foaming agent.

In the case of using the pigment composition as the coloring composition according to the present invention, the pigment composition includes a known pigment and a pigment, wherein the pigment generally includes a protein, a glue rubber resin, a fibrin ester, or the like. Although used, a synthetic resin, for example, a polyurethane resin or the like, which can act as a binder resin, is preferably used. In addition, when the pigment composition includes a synthetic binder resin as an agent, in order to prevent hardening of the binder resin, preferably, 0.5 to 3% by weight of a crosslinking agent may be further included based on the total weight of the pigment composition. Crosslinking agents are, for example, water-soluble melamines, formaldehyde-melamine and formaldehyde-urea resins or precondensates, for example trimethylolmelamine, hexamethylolmelamine or dimethylolurea, or formamide, thiourea, guanidine , Cyanamide, dicyandiamide and the like are used.

In the printing method of the flocking fabric according to the present invention, the drying step (S30) performed after the stamping step is a step of drying the inlaid flocking fabric at a temperature of 70 to 150 ° C. More specifically, the flocked fabric inlaid is transferred to a chamber type dryer and dried at a temperature of about 70-150 ° C., preferably 90-130 ° C. If the drying temperature of the drying step (S30) carried out after the innal step is less than 70 ℃ drying rate is slow and may not proceed as desired, if the drying temperature exceeds 150 ℃ deformation of the flocking fabric or colorant composition and Damage may occur. The drying time can be controlled by the rate of evaporation of water, which is typically about 0.1 to 10 minutes, preferably about 0.5 to 5 minutes.

In the printing method of the flocking fabric according to the present invention, the heating step (S40) performed after the drying step (S30) is a step of treating the dried flocking fabric with steam at 110 to 180 ° C. to heat the colored composition to adhere to the fabric. to be. More specifically, the dried flocked fabric is transferred to a chamber type vaporizer and treated with steam at about 110 to 180 ° C, preferably 140 to 160 ° C. If the steam temperature used in the steaming step is less than 110 ℃ dyeing is not performed properly, the color composition may fall out in the washing step after the steaming step, the flocking fabric may fade color, the steam temperature exceeds 180 ℃ If you do so, the economy is lowered due to excessive energy consumption and the flocking fabric may be damaged. At this time, the steaming time is about 10 to 100 minutes, and preferably about 20 to 60 minutes. In addition, the pressure of the steam used is characterized in that about 1.2 ~ 3.0 kg _f / ㎡, preferably about 1.5 ~ 2.0 kg _f / ㎡.

The washing / drying step (S50) performed after the heating step (S40) in the printing method of the flocking fabric according to the present invention is a step of washing and drying the heated flocking fabric with water of 20 to 70 ° C. Conventional printing method of flocking fabric did not include a washing step because of the economical deterioration due to the addition of a work process and apparatus, because of this, when rubbing the printed flocking fabric, such as a coating agent present on the surface of the fabric Blowing of powder occurred and frictional fastness was not applicable to hospitals, infants, etc., the durability was poor. On the other hand, the color fading phenomenon occurs when the water washing step in the conventional method of printing the flocking fabric has a problem that the quality of the printed flocking fabric is greatly reduced. The printing method of the flocking fabric according to the present invention has a predetermined friction fastness without a color fading phenomenon even though the water washing process is performed through a combination of the edge step and each process condition by a rotary screen printer, and the powder blown by friction It provides flocking fabric with various colors and design without any phenomenon. The temperature of the water used for washing in the washing / drying step (S50) according to the present invention is preferably about 20 ~ 70 ℃, preferably 30 ~ 60 ℃. If the temperature of the water used for washing is less than 20 ° C, it is insufficient to remove the weakly adhered foam from the flocking fabric. If the water temperature exceeds 70 ° C, the strongly adhered to the flocking fabric. And loss of colorant. The flushed flocked fabric is then dried at room temperature or at a temperature of about 70-150 ° C., preferably 90-130 ° C.

Another aspect of the present invention relates to a flocking carpet comprising a flocking fabric printed by the printing method of the present invention, Figure 3 shows a cross-sectional structure of the flocking carpet according to a preferred embodiment of the present invention. As shown in FIG. 3, the flocking carpet according to the preferred embodiment of the present invention includes a bubble layer 110; A pile layer 120 formed of pile yarns planted on an upper surface of the bubble layer by flocking; And a support layer 160 having a form in which the first polymer pad layer 130, the glass fiber layer 140, and the second polymer pad layer 150 are sequentially stacked on the bottom surface of the bubble layer.

Bubble layer

In the flocking carpet according to a preferred embodiment of the present invention, the bubble layer is made of a woven fabric or a nonwoven fabric, and for example, a fiberglass fabric may be used. However, when the glass fiber fabric is used as the bubble layer, the elongation is small, so wrinkles are easily generated, and the economical efficiency is low due to the high price of the glass fiber fabric. Therefore, in the flocking carpet according to a preferred embodiment of the present invention, the bubble layer is preferably selected from the group consisting of polyester fibers or polypropylene fibers in a spunbond method, a melt brown method, a needle punching method, and a water interlocking method. A polyester nonwoven fabric or a polypropylene nonwoven fabric having a structure joined in a web form in an open manner is used. More preferably, a PET (Polyethylene terphethalate) nonwoven fabric having a high strength is manufactured by using a spunbond method. The basis weight of the nonwoven fabric constituting the bubble layer is characterized in that more than 60 g / ㎡, more preferably more than 80 g / ㎡, if the basis weight is less than 60 g / ㎡ the nonwoven fabric is too thin to coat the olefin on the top surface It becomes difficult to work, and there is a possibility that workability | operativity may be inferior in flocking the fiber (for example, nylon fiber) which forms a pile layer by flocking. The upper limit of the nonwoven basis weight is not limited, but will be limited by the raw material and manufacturing method of the nonwoven fabric.

The nonwoven fabric forming the bubble layer according to the invention is preferably coated on its upper surface with an olefin resin. The process of planting fibers (eg nylon fibers) on the top surface of the nonwoven fabric by flocking generally involves applying an adhesive to the top surface of the nonwoven fabric and then attaching the fibers (eg nylon fibers) on top of the static electricity. It consists of the process of fixing the fiber by using the chapter, when using the non-olefin coated nonwoven fabric, the adhesive flows down through the surface of the nonwoven fabric, which may cause a problem of increasing the amount of adhesive used. The olefin resin used to coat the upper surface of the nonwoven fabric may be any one selected from the group consisting of polyethylene resins, polypropylene resins, polyisobutylene resins, and mixed resins thereof, and is preferably convenient in workability. Polyethylene resins can be used.

Pile

In the flocking carpet according to a preferred embodiment of the present invention, the pile layer is formed by flocking pile yarns to the upper surface of the bubble-coated bubble layer coated with an adhesive, forming the surface of the carpet fabric, the carpet product It gives a cushion. The pile yarn constituting the pile layer may be any one selected from the group consisting of nylon fibers, polyethylene fibers, rayon fibers, and mixed fibers thereof, and is preferably nylon fibers. Nylon fiber has a self-extinguishing property that can generate carbon dioxide by itself in the event of a fire, and when nylon fiber is used as the pile yarn constituting the pile layer, the flame resistance of the flocking carpet can be improved.

The length of the pile yarn constituting the pile layer is not particularly limited, but is preferably 1 to 5 mm, more preferably 2 to 4 mm. If the length of the pile yarn is less than 1 mm, the cushioning of the flocking carpet may be reduced. If the length of the pile yarn exceeds 5 mm, interference between pile yarns occurs during the planting process due to flocking. It may not be smooth to incline the yarn in a direction or to stand it vertically.

The fineness of the pile yarn constituting the pile layer is not particularly limited, but is preferably 5 to 50 denier, and more preferably 10 to 20 denier. If the fineness of the pile yarn is less than 5 denier, it may be too thin to make it difficult to grow by flocking. If the fineness of the pile yarn exceeds 50 denier, the number of pile yarn that can be planted per unit area of the bubble layer is limited and There is a fear that the density of pile yarns is lowered and the characteristics expressed from the flocking carpet (blocking penetration of contaminants, blocking ticks, breeding of bacteria, possible cleaning of water, etc.) are reduced.

The number of pile yarns in the pile layer is characterized in that more than 60 million, preferably 80 million or more per square meter area of the bubble layer, the space between piles forming the pile layer is less than 60 million per square meter area of the bubble layer. There is a possibility that the characteristics (i.e., the density of pile yarns are reduced) decrease in the characteristics (blocking penetration of contaminants, blocking ticks, breeding of bacteria, possible cleaning of water, etc.) expressed from the flocking carpet. There is no upper limit to the number of wool pile yarns per square meter area of the bubble layer, but the fineness, length and flocking process conditions of the pile yarns forming the pile layer will be limited.

Support layer

The support layer is formed by coating a first polymer, a glass fiber fabric, and a second polymer in order on the lower surface of the bubble layer in which pile yarns are planted, and the first polymer pad layer 130, the glass fiber layer 140, and the second polymer. The polymer pad layer 150 is stacked in order. The first polymer pad layer and the second polymer pad layer serve to maintain the shape of the flocking carpet, and the glass fiber layer imparts morphological stability (dimension stability) to the flocking carpet.

The first polymer and the second polymer used to form the first polymer pad layer and the second polymer pad layer are polyvinyl chloride resin, styrene-butadiene rubber (SBR), natural rubber, polypropylene resin, and polyurethane resin. It may be selected from the group consisting of, and it is preferable that it is a polyvinyl chloride resin in view of workability, economy, and versatility. In particular, the first polymer pad layer and the second polymer pad layer may be manufactured in the form of a foam, in which case the first polymer pad layer and the second polymer pad layer may be formed of a flocking carpet formed of glass fiber layers. Stability) and give elasticity when the user steps on the flocking carpet installed on the floor, thereby serving to keep the user's sense of comfort. When the flocking carpet is actually applied to the floor, it is divided into a tile type and a roll type. When the first polymer pad layer and the second polymer pad layer are non-foamed, the tile type is mainly a tile type. ), And in this case, the shape stability (dimension stability) is important, so a glass fiber layer should be formed between the first polymer pad layer and the second polymer pad layer. However, when the first polymer pad layer and the second polymer pad layer are in the form of a non-foaming body, the first polymer pad layer and the second polymer pad layer are mainly processed into a roll type. In this case, the first polymer pad layer and the second polymer pad layer and the second polymer pad layer have low importance. Even if the glass fiber layer is not formed between the polymer pad layer can serve as a support layer.

For flocked carpets having a bubble layer of polyester nonwoven or polypropylene nonwoven, the strength of the nonwoven fabric (average basis weight is about 80 g / m2) is usually the strength of the glass fiber fabric (average basis weight is about 170 g / m2). Shape stability (dimension stability) may decrease. In order to compensate for this, the support layer according to the present invention includes a glass fiber layer in which a glass fiber fabric is impregnated between the first polymer pad layer and the second polymer pad layer. Unlike the bubble layer formed of the glass fiber fabric, the glass fiber layer according to the present invention is trapped in two polymer pad layers, and thus, when the flocking carpet is applied to the floor, the glass fiber layer is hardly exposed to the outside, and thus may be generated by the glass fiber. May prevent irritation, skin disorders, shortness of breath, nausea, vomiting and diarrhea. The glass fiber fabric used for the glass fiber layer according to the present invention is not particularly limited in basis weight, and may have a loose structure having a smaller number of wefts and warps per unit area than the glass fiber fabric used as a bubble layer in a conventional flocking carpet. . The basis weight of the glass fiber fabric used as the bubble layer in the conventional flocking carpet is about 170 g / ㎡, according to the present invention even when the glass fiber layer is formed of a glass fiber fabric having a smaller basis weight than the bubble layer It has almost the same form stability (dimension stability) as the flocking carpet used.
