Method of manufacturing blind slate for venetian blinds, and blind slate for venetian blinds manufactured therefrom {Method of manufacturing blinds slate for venetian blinds and blinds slate for venetian blinds employing the same}

The present invention relates to a method of manufacturing a blind slit for a Venetian blind, and a blind slit for a Venetian blind produced therefrom, more specifically, by hot-fixing the woven fabrics of warp and weft through lamination and binder resin, It relates to a method of manufacturing a blind slit for venetian blinds that combines light and required strength, and is capable of producing various patterns according to the fabric pattern of the fabric itself, and a blind slit for venetian blinds produced therefrom.

Recently, as the construction method has been changed into an energy-saving type, the blind-related market is expanding, especially in indoor spaces where most people spend the most time in their daily lives, such as privacy protection and light blocking (ultraviolet rays, infrared rays). The use of blinders for the purpose can be said to be essential.

In the blind product line, a plurality of blind slits are connected through a tow line to develop through elevating of the blind slits, and venetian blinds to adjust the shading state through adjustment of the folding angle of the blind slits, and to adjust the winding state of the screen. It is largely divided into fabric blinds, such as roll blinders that control the light-shielding state, and combination screens that control the light-shielding state by adjusting the winding state of the screen formed by alternating the light-shielding section and the light-transmitting section.

Here, the blind slat of the venetian blind is composed of a panel such as wood or aluminum, and is configured to ensure stable durability and shading performance.

However, the blind slits made of the wood or aluminum panels are heavy and costly according to manufacturing. In particular, the wood blind slits have a beautiful appearance by providing a pattern of wood itself, but when exposed to a large amount of humidity, mold, etc. It is caused by the problem that the germs of the bacteria are to be reproduced and torsion occurs.

On the other hand, in the context of the present invention, the laminate is formed by absorbing and flame-retarding the laminate of the non-flammable or flame-retardant resin material serving as a core material using an adhesive with an additive-free fiber or / and an artificial fiber having flame-retardant water-absorbing properties. A technique has been proposed in which a flame-retardant thin laminate obtained by heating and molding a sieve and flame-retarding the outer layer of the laminate is used as a blind slat.

As described above, the blind slit molded by adhering the fiber to the resin through an adhesive has characteristics of light weight and no warpage or distortion. However, the blind slit can easily cause peeling of the adhered fibers, and it is difficult to secure the required thermal insulation, while manufacturing difficulties such as damage to the fabric structure of the fibers adhered to the cutting process may be caused.

Particularly, in this embodiment, the weaving section 11 in which the warp 10b and the weft yarn 10a are woven on the woven fabric 10; The weaving edge 240 is alternately formed by alternately forming the section 12 made of only the warp 10b without inputting the weft 10a, so that the cutting edge 240 in the cutting process described later is woven with the warp 10b and the weft 10a crossed. By not cutting the weaving section 11 of the state, and cutting the cutting section 12 made of only the slope 10a, the weaving pattern of the fabric 10 is damaged during the cutting process or the shape of the cutting surface is uneven. To prevent the phenomenon of being exposed to the outside by being loosened, or the strands of the weft yarns 10a locally detached from the fabric 10.

Here, since the cutting section 12 is lost in the fabric 10, it is preferable to minimize the loss of the fabric 10 by forming it with a minimum width.

Therefore, the present invention is performed by alternately performing a weaving process consisting of a weave (10a) and a weave (10b) cross weave and a weave process consisting of only the slope (10b), weaving section (11) and cutting section (12). The alternating width of the fabric 10 is produced.

[Slitting process]

In this process, as shown in FIGS. 2 and 4, in the fabric 10 formed by alternating the weaving section 11 and the cutting section 12 through the weaving process (S 10), the cutting section 12 is formed. By cutting some of the inclined strands of the inclined (10a) strands, the weaving section 11 forms a textile paper 10 interconnected by the cutting section 12, wherein the cutting section 12 is the weaving section 11 Make sure that only the smallest number of strands that can connect is left.

In the present embodiment, the cutting die 210 is formed by cutting the cutting die 210 with the cutting edge 211 formed on the fabric 10, which extends in the longitudinal direction and moves at intervals of unit length, and the cutting edge of the cutting die 210 is elevated. Of the slopes 10b formed in the cutting section 12 by 211, only the slopes 10b that require cutting are to be cut out and removed.

In the present invention, for example, by cutting 50% to 90% of the inclined strands among the inclined strands formed in the cutting section 12, the cutting section 12 is configured to remain only 50% to 10% inclined strands.

Then, the fabric paper 10 after the spinning process (S 20) is re-wound on a winding roll, and a binding resin coating process (S 30) described later is performed.

[Binding resin application process]

In this step, a binding resin 20 made of a thermoplastic material is applied to the surface of the fabric paper after the weaving process (S 10) and the spinning process (S 20).

In this embodiment, the textile paper 10 wound on a winding roll is continuously developed, and a binder resin 20 in a gel state is applied to the surface of the textile paper 10 to be unfolded, and then scraped through a scraper, thereby making the textile paper 10 The provider resin 20 having a set thickness is formed on the surface.

Here, the binder resin 20 may be a thermoplastic resin such as PE, PP, PET, or a thermosetting resin such as epoxy. In the present invention, as an example, the binder resin 20 made of an epoxy resin which is a thermosetting resin is fabric. (10).

In addition, the binder resin 20 may be configured such that various decorative elements in powder form, such as gold powder or silver powder, which can provide a decorative taste, are incorporated, thereby improving the surface aesthetics of the manufactured bleed itself.

Particularly, in the present embodiment, the blind slit 1 itself is interposed between the at least one of the laminated fabrics 10 by interposing an insulating sheet 30 made of an aluminum thin film and interposing the insulating sheet 30. The insulating properties of the venetian blinds, which include this, ensure a stable insulating function together with a shading function.

Here, the heat insulating sheet 30_ is made of a thin aluminum thin film having a thickness of 0.01 mm to 0.03 mm, so as to secure heat insulation without affecting the overall thickness.

Therefore, the binder paper 20 is applied to the wrapping paper 10 wound on each roll, and the binder paper 20 is coated with the binder resin 20 is alternately stacked with the insulating sheet 30, A blind slit panel 100 of full width is formed through a hot compression process (S40) described below.

[Lamination and hot pressing process]

As shown in FIGS. 2 and 5 and 6, this process is performed by hot pressing the fabric 10 coated with the binder resin 20 at a set pressure and a set temperature through a hot pressing mold 230 to be hot-cured. This is a process in which the binder resin 20 and the laminated paper 10 and the insulating panels 30 form a full width blind slit panel 100 solidified in a panel form.

In this embodiment, as shown in FIG. 5, prior to hot pressing the stacked fabrics 10 through the hot pressing mold 230, an insulating sheet made of an aluminum thin film through the punching mold 220 formed with the punching pins 221 By performing a perforating process of compressing the laminated fabric papers 10 through 30, the fusion holes 31 penetrated up and down are formed on the insulating sheet 30 interposed between the fabric sheets 10. .

When the perforation process is performed through the perforated pins 221 in this way, the heat insulation sheet 30 disposed between the fabrics 10 is formed with tubular drawn fusion holes 31, and the tubular drawn fusion The groundings 31 are cocked between the tissues of the laminated fabric 10 to form a pre-fixed state with the tissues 10.

The fabric 10 coated with the binder resin 20 that has undergone such a perforation process is hot-pressed at a set pressure and set temperature through a hot press mold 230 in a decompression chamber, and a binder resin 20 cured hot The laminated fabrics 10 form a full width blind slit panel 100.

At this time, as shown in Figure 6, the pressing surfaces 231 and 232 of the hot pressing mold 230 to promote hot pressing of the laminated fabric 10 are configured to be curved upward and downward, and concaved and curved. The weaving section 11 of the fabric 10 is compression molded in a curved shape through curved pressing surfaces 231 and 232.

When configured in this way, as shown in FIG. 1, the blind slit 10 made of the weaving section 11 is formed into a curved curve shape, and has improved bending strength while having a thin thickness.

Here, the hot pressing conditions including pressure, temperature, pressing time, etc. according to the hot pressing of the laminated fabric 10 are appropriately performed depending on the thickness of the laminated fabric, the amount of lamination, and the type and amount of the binder resin. Can be.

In addition, the hot pressing process through the hot pressing mold 230 is performed in a depressurization chamber in which a depressurized state is formed, and the air remaining in the laminated fabric 10 and the binder resin 20 applied to the fabric 10 is removed. Residual phenomena are suppressed, and a large amount of air bubbles do not remain in the blind slit panel 100 of the entire width.

[Foundation process]

On the other hand, this process is a process of finally cutting the blind slat panel 100 of the molded full width at a set interval, as shown in FIGS. 2 and 7, to finally obtain a venetian blind blind slit 1 having a set width. to be.

The cutting process (S 50), by placing the cutting blade on the lower part of the cutting mold, the lifting cutter type and the rotating blade to cut the cutting blade vertically into the blind slit panel of the full width by lifting the cutting mold to the blind slit panel. It can be adopted in various forms such as a rotary cutter type that cuts in the width direction to cut the blind slate panel at a set interval.

However, in this embodiment, the insulated cutting blade 240 heated by cutting the heated heat transfer cutting blade 240 into the cutting section 12 made only of the slope in the blind slit panel 100 requiring cutting in the vertical direction or the width direction ) To cut the cutting section 12 formed on the blind slit panel 100 by hot cutting.

At this time, the cutting section 12 of the blind slit panel 100 is composed of only the inclination 10b, unlike the weaving section 11 in which the inclined 10b and the weft yarn 10a are woven in a plain weave shape.

Particularly, in the present invention, 50% to 90% of the inclined (10b) strands are cut out and cut out of the entire inclined strand forming the cutting section 12 by adding a spinning process (S 20), thereby cutting 12 ) Was left with only 50% to 10% warp strands.

Therefore, the present invention minimizes the load generation of the cutting blade as it cuts the woven warp 10b and the weft yarn 10a through the cutting blade or the heat-transfer cutting blade 240.

In addition, the fabric tissue of the fabric 10 forming the blind slit 1 is blurred due to load generation, or the weft section 10a of the weaving section formed in the blind slit 1 is locally exposed through the cut surface and cut. The phenomenon in which the cut surface of the blind slat 1 becomes defective can be prevented.

On the other hand, the blind slit 1 for venetian blinds according to the present invention formed through a series of processes, as well as having a stable heat insulation by the heat insulating sheet 30 provided between the fabric (10), as well as a curve It has a stable bending strength even if it is bent and manufactured in a thin thickness.

Particularly, in the present invention, the inclination 10b and the weft yarn 10a are not woven into the cutting section 12 through the weaving process (S 10) and the weaving process (S 20), and the inclination of several strands (10b) By constructing only), excessive external force is not required by cutting the cutting section 12 formed between the weaving sections 11 made of a bleed, and stable cutting is performed so that the cut surface has a smooth appearance.
