Description

Manufacturing method of black out blind fabric for roll screens}

The present invention relates to a method of manufacturing a blackout blind fabric for a roll screen, and more particularly, by forming a coating layer that performs a blackout function and a flame retardant function on the surface of a woven fabric paper to be laminated, the blackout film and insulation by the laminated cured coating layer And it relates to a method of manufacturing a blackout blind fabric for a roll screen to have both flame retardancy.

Typically, a window blocking device is used for privacy protection, blocking or controlling the amount of light, and interior interior.

There are various types of curtains, verticals, blinds, roman shades, tinting, roll screens, etc., and consumers purchase and install the products they want in consideration of the purpose of use, the window structure, and their preferences.

Among them, the roll screen is a window blocking device that adjusts the height of the screen fabric by rolling up or unrolling the screen fabric acting as a curtain in a roll form.

In general, double fabrics are used for a variety of purposes such as blackout paper or curtain paper after weaving a surface fabric and a back fabric as a bonding structure to give various functions and aesthetics.

Looking at the prior art related to the double fabric, Patent No. 10-0554961 "Double Fabric" (Patent Document 1) and Patent No. 10-0974443 "Double Fabric with Wrinkles and Its Manufacturing Method" (Patent Document 2 ), and Patent Publication No. 2009-20439 "double fabric for curtains" (Patent Document 3) and the like have been provided.

Looking at the technical contents of Patent Document 1, in the double fabric comprising the front and back fabrics with the weft yarns, the stitching yarns made of yarns with easy moisture transfer are used to form the structure of the front and back fabrics. It is made to consist of a double fabric as a stitching structure in which the warp or weft yarns are interlaced, and at the same time, the surface fabric and the back fabric are alternately connected.

Therefore, the moisture in the backing fabric is moved to the surface layer where the surface fabric is exposed by the stitching yarn to facilitate water discharge.

In addition, a review of the technical content of Patent Document 2 shows that in a double fabric with a three-dimensional pattern of wrinkles on one side, separately woven low shrinkage fabric and high shrinkage fabric are overlapped side by side, but the high shrinkage fabric is pulled in all directions and stretched. And, in the above state, by sewing in a straight or curved shape, the low-shrinkable fabric and the high-shrinkable fabric are joined to form a double fabric, and then the tension is removed from the high-shrinkable fabric to make it shrink. That is, it allows three-dimensional wrinkles of the form to be formed.

In the case of the double woven fabric, the low-shrink fabric and the high-shrink fabric are woven separately, and then, while the high-shrink fabric is pulled and stretched, the low-shrink fabric is overlapped and sewn, and tension is removed to form three-dimensional wrinkles on the low-shrink fabric. , Not only the manufacturing process was complicated, but also limited to use mainly for clothing, and the continuity of work was deteriorated, and it was difficult to expect a shading effect.

Examining the technical content of Patent Document 3, a battery woven with a first weft and a first warp, and a second weft and a second warp that are thinner than the first weft and the first warp of the battery, which are bonded to the rear of the battery. A densely woven fuji is provided, and the first weft of the battery and the second slope of the fuji or the first inclination of the battery and the second weft of the fuji are intersected at regular intervals, and the battery and the fuji are combined. A coating film was formed on the back side.

Therefore, in the case of the double-woven fabric of the above configuration, it can be expected that the effects of shading, insulation and sound insulation can be expected when used for curtains, but the manufacturing process is somewhat complicated and the wrinkle effect cannot be expected, so it cannot be differentiated from ordinary double-woven fabrics. There is a drawback.

In order to solve this problem, as a fabric for blackout blinds, a foam blackout fabric having excellent blackout accuracy has been developed and used.

In Korean Patent Application Publication No. 10-2010-0009425, a foaming step of foaming acrylic, water-based polyurethane or EVA, a foam coating step of coating a foamed coating layer on one side of the fiber by an overroll or knife coating method, and titanium oxide are contained. To present a method for producing a black screen, comprising a pigment coating layer forming step of applying the colored pigment to the foam coating layer, a drying step of drying the foam coating layer by passing through a drying device, and a curing step of curing the foam coating layer. have.

In the case of such a foam blackout fabric, there is a problem in that foam is generated during foam formation and is susceptible to scratches during work, so that it is easily scratched even by a small friction, resulting in severe product damage and a stiff touch of the blackout fabric.

Patent No. 10-0554961 "Double Fabric" Patent No. 10-0974443 "Double fabric with wrinkles and its manufacturing method" Patent Publication No. 2009-20439 "Double fabric for curtain" Korean Patent Publication No. 10-2010-0009425
