Description

Manufacturing method of black-out fabric for roll blinds}

The present invention relates to a method of manufacturing a blackout fabric for roll blinds, and more particularly, a blackout foam formed to be laminated on the back side of the fabric fabric and the fabric fabric by forming a plurality of blackout foam coating layers on the back side of the woven fabric fabric. Stable blackout performance by the coating layer is secured, and stable blackout performance and durability are sustained by preventing pinholes or cracks in the blackout foam coating layer formed by laminating on the back side of the fabric fabric, and the delamination of the blackout foam coating layer from the fabric fabric. It relates to a method of manufacturing a blackout blind paper for a roll screen to be secured.

As is well known, the window blocking device is used for indoor interior as well as protecting privacy and blocking or controlling the amount of light.

There are various types of curtains, verticals, blinds, roman shades, tinting, roll screens, etc. 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 the surface fabric and the back fabric as a bonding structure to give various functions and aesthetics.

Examining 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 content of Patent Document 1, in the double fabric comprising the front and back fabrics of 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, so that moisture can be easily discharged.

In addition, a review of the technical content of Patent Document 2 shows that in the double fabric having a three-dimensional pattern of wrinkles on one side, separately woven low-shrink fabric and high-shrink fabric are overlapped side by side, but the high-shrink fabric is pulled and stretched in all directions. 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 surface 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 effect 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 the general double-woven fabric. There is a drawback.

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

In Korean Patent Laid-Open 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 overall 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, bubbles may occur during foam formation, causing a pinhole phenomenon, and a tight bonding state between the fabric fabric and the foam blackout layer is not secured, so the foam blackout layer is separated from the fabric fabric when used for a long time. It is pointed out that it is difficult to ensure durability, such as peeling may be caused, and the foam blackout layer is cracked when exposed to sunlight for a long time.

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 paper for curtains" Korean Patent Publication No. 10-2010-0009425

Hereinafter, a process of forming each dark film foam coating layer will be described in detail with reference to FIGS. 1 to 5.

[Lower blackout foam coating layer formation process]

In this process, as shown in Figs. 1 to 4, the black film coating liquid application process of applying the black film foam coating liquid through the coating liquid injection member 110 on the back surface of the fabric moving in the longitudinal direction, and the J-type knife member 120 By scraping the back surface of the fabric fabric 10 through the scraping process, the black film foam coating solution applied to the back surface of the fabric fabric 10 is uniformly flat while maintaining a thickness of 0.1mm to 0.15mm.

In this embodiment, before applying the dark film foam coating solution to the back surface of the fabric moving in the longitudinal direction, the brush forming roller 140 having a plurality of scratch pins 141 formed on the outer diameter is rotated circumscribedly to the back surface of the fabric fabric. It further includes a brushing forming process in which the napped (10c) generated by locally cutting the warp forming the fabric fabric is formed by standing on the back side.

In particular, the present embodiment further includes an instantaneous heating process of instantaneously radiating hot heat for 0.5 seconds to 1.5 seconds at a temperature of 150° C. to 160° C. through the hot member 150 to the raising (10c), The ends of each of the brushed hairs 10c are bent by the heat provided by instantaneous copying so that they are transformed into a hook shape.

When the brushing is formed on the back side of the fabric fabric through the brushing forming process as described above, the blackout foam coating liquid applied to the backside of the fabric is fixed to each of the brushed fabrics, and as a result, the blackout foam coating liquid and the fabric fabric are formed by the brushing. The bonding force between the back surfaces can be increased.

In this way, the fabric fabric that has completed the brush formation process and the first coating process is passed through a tenter with a drying condition of 120°C to 140°C in the hot heating process, and the dark film foam coating liquid applied to the back surface of the fabric is set to a set thickness. The cured lower blackout foam coating layer 11 is formed.

At this time, each raised (10c) formed on the back surface of the fabric fabric (10) is instantaneously heated by the hot member (150) and transformed into a hook shape, so the lower blackout foam coating layer (11) is a hook-shaped raising (10c). ) To form a more stable bonding state, and as a result, the lower blackout foam coating layer forms a more stable adherence state to the back side of the fabric.

More preferably, an electrostatic generating member 151 is disposed in front of the hot member 150 to generate static electricity by friction with the raising (10c), and each of the raising (10c) is provided in the electrostatic generating member (151). It is instantaneously heated by the hot member 150 in an upright state by the generated static electricity, so that the end is shaped into a hook shape.

Thereafter, the fabric fabric, which has undergone a hot drying process while passing through the tenter, is subjected to a post-pressing process in which roll compression is performed while passing between the crushing rollers 130.

Preferably, the fabric fabric 10 discharged through the hot drying process is not directly passed between the crushing rollers 130 to perform a post-pressing process, but when cooled to a temperature of 70°C to 60°C, crushing A post-pressure process is performed by passing between rollers and pressing the roll.

Accordingly, the lower black film foam coating layer formed on the back surface of the fabric fabric by roll compression through the post-press process maintains a uniform density and uniform thickness, and pinholes remaining in the lower black film foam coating layer can be removed.

[Intermediate blackout foam coating layer formation process]

This process is a process of forming an intermediate black film foam coating layer 12 made of a foam coating layer to be laminated on the lower black film foam coating layer 11 formed on the back surface of the fabric fabric 10.

In this process, the black film foam coating liquid is applied to the back surface of the fabric fabric 10 moving in the longitudinal direction through the coating liquid injection member 110, and the intermediate black film foam coating liquid 12 is applied to the back surface of the lower black film foam coating layer 11. During the process of applying the black film coating liquid and by scraping the back side of the fabric fabric 10 through the J-type knife member 120, the black film foam coating liquid applied to the lower dark foil foam coating layer 11 maintains a thickness of 0.05 mm to 0.1 mm. It includes a scraping process to make it evenly flat.

Through the process of applying the blackout coating and scraping as described above, the fabric fabric 10 coated with the blackout foam coating liquid on the back surface of the lower blackout foam coating layer passes through a tenter in which drying conditions of 120°C to 140°C are formed during the hot heating process. While forming the middle black film foam coating layer 12 cured by the black film foam coating solution applied to the back surface of the fabric.

Thereafter, when the fabric fabric after the hot drying process is cooled to a temperature of 70° C. to 60° C., a post-pressure process of passing through the crushing rollers 130 and pressing the roll is performed, so that it is compressed by the crushing roller 130. As a result, the intermediate foam coating layer 12 formed on the back surface of the fabric has a uniform density and a uniform thickness.

[Formation process of upper blackout foam coating layer]

This process is a process of forming an upper black film foam coating layer 13 on top of the intermediate black film foam coating layer 12 by forming a black film foam coating solution on the intermediate foam coating layer 12 formed on the back surface of the fabric. .

In the same way, in this process, the black film foam coating solution is applied to the back surface of the fabric fabric 10 on which the intermediate black film foam coating layer 12 is formed through the coating liquid injection member 110, and the rear surface of the intermediate black film foam coating layer 12 is applied. The black film coating liquid application process of applying the black film foam coating liquid on the surface, and the black film foam coating liquid applied by scraping the back side of the fabric fabric 10 through the J-type knife member 120 are uniformly maintained while maintaining the thickness of 0.05mm to 0.1mm. Includes a scraping process to make it flat.

As described above, through the process of applying the blackout coating and scraping, the fabric fabric 10 coated with the blackout foam coating liquid on the back surface of the intermediate blackout foam coating layer 12 is formed under a drying condition of 120°C to 140°C in the hot heating process. While passing through the rubble, the upper black film foam coating layer 13 is formed by curing the black film foam coating liquid applied to the intermediate black film foam coating layer.

Thereafter, the fabric fabric 10 after the hot drying process is cooled to a temperature of 70°C to 60°C, and then passed between the crushing rollers and subjected to a post-pressing process in which the roll is pressed, and the fabric fabric is compressed by the crushing roller. The intermediate foam coating layer formed on the back side of the has a uniform density and uniform thickness.

Particularly, in this embodiment, the fibers h(14) made of filament cilia to the black film foam coating liquid flattened through the scraping process are scattered and supplied through a scattering supply member 160 that scatters through pneumatic pressure, and then, J-type By scraping the back side of the fabric through a knife member, the dispersed oil?h(14) may further include a fiber?h scattering supply process in which the blackout foam coating liquid intersects irregularly on the surface.

In the present invention, the fibers?h(14) are not mixed with the blackout foam coating solution by adding them to the blackout foam coating solution itself, and the short fibers?h are scattered through compressed air to the blackout foam coating solution applied to the intermediate foam coating layer and supplied. On the bottom, the blackout fibers h do not locally remain on the upper blackout foam coating layer in a lumped state, but are evenly dispersed on the surface of the blackout foam coating solution to cross and form a nonwoven fabric.

That is, in the present invention, short fibers?h are scattered and supplied to the surface of the blackout foam coating solution uniformly dispersed on the back surface of the secondary blackout foam coating layer, so that the scattered fibers?h are supplied by scattering through a separate scattering supply process. The foam coating solution is not locally agglomerated, but is uniformly dispersed to form a crossover state in the form of a non-woven fabric.

Therefore, the short fibers intersected in the form of a non-woven fabric by scattering supplied to the blackout foam coating solution are adhered to the surface of the upper blackout foam coating layer 13, so that the blackout foam coating layers including the upper blackout foam coating layer 13 are systematically fixed. Therefore, it is possible to prevent the occurrence of cracks in the blackout foam coating layers including the upper blackout foam coating layer 13.

On the other hand, the dark film fabric for roll blinds manufactured by the manufacturing method according to the present invention, on the back surface of the fabric fabric 10, the lower foam coating layer 11, the middle foam coating layer 12 and the upper foam coating layer 13 are laminated. As a result, stable blackout performance can be secured by the blackout action by the foam coating layer formed by laminating.

In particular, the lower foam coating layer formed on the back surface of the fabric fabric is more tightly fixed to the back surface of the fabric fabric by the brushing (11c) in a hook shape formed on the back surface of the fabric fabric, and the upper foam coating layer exposed to the outside is scattered. Since the cohesive force between the fibers and h(14) that is supplied and intersected irregularly increases, even when exposed to sunlight for a long time, the foam coating layers formed on the back surface of the fabric fabric are peeled off from the fabric fabric or cracks occur. This deterioration phenomenon can be prevented.
