The present invention relates to a functional fabric wallpaper and a method for manufacturing the same, and more particularly, due to the second flame-retardant treatment to prevent fires to be enlarged in high-rise, deep, clustered housing form, and antifouling, water-repellent, oil-repellent The present invention relates to a fabric wallpaper and a method for manufacturing the same.

Walls are glued to the interior walls of homes and buildings to protect the walls. Usually, such conventional wallpaper is manufactured by paper, vinyl chloride sheet, etc., and there are various kinds such as having various patterns and only simple stripes close to the plain, and recently, it can be wiped with water as water-proof wallpaper and also has a moisture-proof effect. have. By the way, these conventional wallpaper has the advantages of low cost, variety of colors and patterns, and easy drying, compared to wall cloth, but it is not flame-resistant and due to the nature of the material, the fire spreads instantly in the event of fire, which causes numerous casualties. In addition, there is a problem in that the sound absorption effect is poor in a dense residential space does not exhibit a different function.

In other words, urban buildings are becoming taller, deeper and larger, and due to the rapid increase in the handling of various dangerous substances such as electricity, oil, gas, chemicals, etc., accompanied by high economic growth, the aspect of fire is complicated and enlarged. Is in the trend of becoming.

However, in order to extinguish a fire before it spreads to a large topic, it is necessary to prevent the fire from spreading, and the importance of interior materials is increasing for this purpose.

Therefore, in recent years, a flame-retardant wallpaper, a sheet of cardboard, etc. have been developed and marketed. Looking at the example, there is a sticky fabric wallpaper of Korean Patent Publication No. 1999-79616. Such fabric wallpaper is spun yarns of antibacterial and flame retardant staple fibers containing both antimicrobial and flame retardant properties, and then spun into a yarn. After weaving them, resin coating is applied on the back side and adhesive is applied on the back side to give adhesiveness. It is produced by cutting to size.

However, such wallpaper has a disadvantage in that it is difficult to obtain the required flame retardancy because only the first flame retardant treatment is applied, and the contamination is well carried out by bringing a cover sheet or a paper back onto the back of the fabric itself or in a dyed state.

In addition, such a fabric wallpaper is weak to change over time in the case of dyeing, there is a problem that there is a difference in color for each lot (lot), and furthermore, the sound absorption effect that can cope with the noise problem in apartments or high-rise housing conditions, or less luxury as interior materials There are several problems.

In addition, such wallpaper has a problem in that, for example, even if it contains an antibacterial function, the function is greatly degraded due to the paper adhered to the front surface thereof.

The present invention has been made in view of the above-mentioned conventional problems, and its object is to provide a flame retardant and various functional materials on the back side of the fabric to promote the shape stability of the fabric and to be effective for the human body of the occupant. It is to provide a fabric wallpaper and a method for producing the same having an antifouling function.

Another object of the present invention is to prevent the spread to a large fire in the event of a fire by the first flame retardant treatment made of the fabric fabric, and the second flame retardant treatment made in the coating process, for example, antibacterial, humidity control, far infrared rays and anion It provides the fabric wallpaper that is created, deodorized and air purification function is beneficial to the human body of the occupants and creates a comfortable indoor environment and surface treatment is made to enhance the decorative effect by utilizing the unique characteristics of the fabric. have.

Still another object of the present invention is to prepare a step of washing and flameproofing the fabric, and to apply the functional material and the flame retardant to the release paper and dry, and then to apply the adhesive on the upper surface of the fabric to adhere to the back side of the fabric and at the same time to remove the release paper A coating step, a surface treatment of the fluorine-based cationic polymer derivative on the surface of the fabric, and a step of treating the surface to have a moisture-permeable effect and a drying step of winding the fabric and removing volatiles from the drying chamber, so as to have an excellent flame retardant effect. In addition, the surface has a water-repellent, oil-repellent, antifouling function and at the same time provide a method of manufacturing a fabric wallpaper that breathe, that is to have a moisture-permeable function to maximize the various effective functions of the functional material.

Preferably, the object of the present invention is to use a release paper on the back of the fabric to apply a coating liquid mixed with a functional material and a flame retardant in an appropriate ratio, the surface is treated by steam spraying the fluorine-based cationic polymer derivative, coating and adhesion Achieved as a fabric wallpaper completely volatiles added in the process,
