Description

High-gloss net fabric

The present invention relates to a high gloss net fabric, and more particularly, to a wound high gloss net fabric that is wound while being in close contact with the winding rod and that the aesthetics are improved due to high gloss so that no unfolding and tissue deformation occurs.

Indoor spaces, such as homes and offices, are provided with breathable, screen-protected feet, roll screens, and blinds (both vertical and horizontal blinds) to block privacy to protect privacy. Insect screens are installed, and such screens, feet, roll screens and blinds (vertical and horizontal blinds) can all be made of net (net) -shaped fabrics, and each device (frame, rail, etc.) can be used according to its application purpose. Is installed in the window.

Among them, the insect screen is installed on windows made of metal yarns of about 0.15mm aluminum and stainless steel to ensure breathability while preventing insects such as mosquitoes, flies and fly flies from entering the interior spaces such as homes and offices.

However, in the case of the above-mentioned insect-control net, since it is made of metal and is in contact with the outside, rust during use is generated due to rainwater, etc., and in summer when outdoor heat is transmitted to the inside as it is during the daylight hours, And it has a problem that the appearance is not good because it is made only of metal and it can not be installed easily by a general person in the installation and there is a problem that a professional contractor has to install it. In order to secure visibility, There is a problem in that the filterability is deteriorated due to the possibility of intrusion of micro-fly.

The applicant of the present invention has applied the patent application 10 (Patent Application No. 10) to the invention of a netting fabric which protects privacy and improves the appearance of a high-gloss appearance by preventing the interior of the room from being seen when the room is viewed from the outside while eliminating the rust generation and construction difficulties -2010-0097113. As a result, a metallic nano-coating layer is formed on one side of a net made of a synthetic resin monofilament yarn, and the metallic nano-coating layer generates diffuse reflection, It is proposed to protect privacy, prevent rust, prevent external heat from being transmitted to the inside, make eco-friendly, excellent design and privacy possible without detection of harmful substances, and a manufacturing method thereof.

In the above-described applicant of the present invention, high gloss is possible by using monofilament yarn, but since the monofilament yarn is hard, it is a winding type insect screen recently used in porches, windows, etc. (related prior art: Korean Patent Application Publication No. 2002-0021655, registered application 20 -0398773, registration room 20-0398812, etc.), as shown in Figure 1, as well as unfolding and tissue deformation occurs, the net fabric 12 made of monofilament yarn is not tightly wound to the winding rod 14, not being wound Due to the characteristics of the fiber, the size of the housing where the winding rod is installed is increased by winding with a play, especially when the net fabric is required to have a length of about 2m to 2.4m, the size of the housing where the winding rod is installed is too large. There was a problem that can not be applied to grow.

In order to solve this problem, the applicant of the present invention, in Utility Model Registration Application No. 20-2011-0008555, the winding direction yarn of the net fabric is a soft synthetic resin yarn having flexibility and the yarn perpendicular to the winding direction of the net fabric. A net fabric which can be wound using a hard synthetic monofilament yarn is filed.

When the door screen is installed using the fabric, the winding direction is released in a state fixed to the winding rod and the fixing frame during the manufacturing process, and the vertical direction in the winding direction is cut and installed to fit the door size. Since the soft yarns arranged horizontally are removed from the position adjacent to the end, the loosening occurs from the top / bottom of the door screen, and thus there is a problem that the soft yarn does not serve as the screen.

In addition, the net fabric used in the existing winding type screen is usually PVC coated yarn to multifilament yarn in consideration of the price, but multi-filament yarn for PVC coating per actual machine when producing thread with 0.3mm diameter If the daily production amount is about 100kg, when the thread of 0.2mm diameter is manufactured, it can be cut off and the injection tension can not be increased, and because of this, the yarn speed is lowered because productivity can be reduced by only 20kg due to the low speed per minute. There was a problem that the yarn of fine diameter is difficult to produce in reality.

In addition, in order to prevent fine blades and the like while passing through the air, the net fabric's perforation size should be about 0.5 mm, and for this, the diameter of the yarn should be about 0.2 mm, but as described above, the multifilament yarn for PVC coating is about 0.2 mm. Since the diameter of the virtual production is difficult, the hole size is very high in order to implement a fine mesh of less than 0.5mm, and to realize the price, there was a problem that the fine mesh of less than 0.5mm can not be implemented.

In addition, as described above, the net fabric using the PVC coated yarn is not possible to manufacture a fine mesh because the diameter of the yarn is increased due to the PVC coating, it is impossible to have a high gloss due to the properties of multifilament or PVC has an excellent aesthetic. There was a problem.

Accordingly, the present invention has been conceived to solve the above problems, the weaving direction of the net fabric in the weaving net fabric using a soft synthetic resin yarn having flexibility, the circle perpendicular to the winding direction of the net fabric The yarn is made of hard synthetic monofilament yarn, but the PVC synthetic yarn is added between the hard synthetic monofilament yarns to serve as a fusion and fixation of the warp yarn through tenter processing, so that the net fabric is wound to the winding rod during winding. It is to provide a high gloss net fabric that can prevent all loosening during cutting and use, and enables high gloss by hard synthetic resin monofilament yarns and enables the realization of fine nets without burdened production costs.

In order to achieve this object, a feature of the present invention is a winding direction yarn of a net fabric woven at a density of 18-50EA / Inch and an opening size of 450-1000 μm, which is a soft synthetic resin yarn having flexibility, and a winding direction of the net fabric. The yarn in the vertical direction is composed of a hard synthetic resin monofilament yarn and a PVC coated yarn, characterized in that the soft synthetic resin yarn and PVC coated yarn to form a fusion by heat fusion.

At this time, the net fabric is characterized in that it comprises a pattern formed by pressing.

In addition, the net fabric is characterized in that it comprises a metal nano-coating layer formed on one side, and a soft transparent coating layer formed on the other side of the metal nano-coating layer and the metal nano-coating layer of the net fabric is not formed.

According to the present invention, the soft synthetic resin yarn is heat-sealed with the PVC coated yarn, thereby preventing the unfolding and tissue deformation during cutting and use, thereby improving the workability and improving the satisfaction on use.

In addition, since the soft synthetic resin yarn is placed in the winding direction of the net fabric, the net fabric is closely adhered to the winding rod during the winding process, so that the size of the housing where the winding rod is installed is not limited and can be applied to windows or doors of 2 m or more. Will be.

In addition, in weaving the net fabric, the yarn in the vertical direction to the winding direction of the net fabric uses a high gloss monofilament yarn, so the aesthetics caused by the high gloss is improved in observing the net fabric, and the monofilament is a yarn in the vertical direction to the winding direction. Since the use of yarns and PVC coating is not necessary, it is possible to manufacture a fabric having a microstructure, thereby preventing the invasion of fine beetle.

And, by manufacturing a net using a synthetic resin, no rust is generated, external heat is not transferred to the inside, it is possible to provide an eco-friendly insect screen without harmful substances detection, manufactured with synthetic resin yarns including PET monofilament yarn Therefore, it is easy to handle, such as cutting the insect screen, and the strength and flexibility is secured, there is an effect that can be installed by the general public, not a professional contractor.

In addition, there is an effect of protecting privacy by generating diffuse reflection by metal nano-coating to block transparency.

In addition, the PET monofilament yarn uses a low body color such as black or blue, and the metal nano-coating layer is formed outdoors, but since the interior is low in color, it absorbs light, so the visibility is secured even if the number of strands per inch increases. As it has an easy effect and can make a lot of strands per inch in this way, when the opening size becomes 450-1000㎛ and the opening size is less than 550㎛, it is possible to completely block the fine blade (domestic minimum size 550-600㎛). have.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 2, the net fabric 50 according to the present invention is made of a soft synthetic resin yarn having a density of 18-50EA / Inch and an opening size of 450-1000 μm, and having flexibility in the winding direction of the net fabric ( 20) and a hard synthetic resin monofilament yarn 30 disposed in a direction perpendicular to the winding direction of the net fabric, and arranged together with the monofilament yarn 30 in a direction perpendicular to the winding direction of the net fabric. It consists of a synthetic resin yarn 20 and the PVC coated yarn 32 is heat-fused through the tenter processing at 180 ~ 220 ℃ formed fusion portion 34.

As shown in FIG. 2, the net fabric 50 according to the present invention is a soft synthetic resin yarn 20 having a flexibility in the winding direction of the net fabric woven at a density of 18-50EA / Inch and an opening size of 450-1000 μm. The yarn in the direction perpendicular to the winding direction of the net fabric is a hard synthetic resin monofilament yarn 30 and a PVC coated yarn 32 are disposed, respectively, the soft synthetic resin yarn 20 and the PVC coated yarn 32 The fusion unit 34 is formed by thermal fusion through the tenter processing at 180 ~ 220 ℃.

Examples of the soft synthetic resin yarn in the above may be used by coating the PET-based elastomer, PBT-based elastomer, urethane-based elastomer, multi-filament yarns, or PVC coated synthetic fiber monofilament yarns.

In addition, examples of the hard synthetic resin monofilament yarn is a low saturation polyethylene terephthalate (hereinafter referred to as PET) monofilament yarn such as a black series.

PVC coated yarn is PVC coated on the outer circumference of the multifilament yarn or monofilament yarn.

In the above tenter processing, the net fabric is passed through a 180-220 ° C. tenter to heat-bond the soft synthetic yarn and the hard synthetic monofilament yarn constituting the net fabric, and the temperature of the tenter is maintained below 180 ° C. In this case, the fixing force due to thermal fusion is lowered, and if it exceeds 220 ° C, the yarn is deformed by high temperature.

The soft synthetic resin yarn and the PVC coated yarn constituting the net fabric by the tenter processing are combined by thermally fusion as shown in Fig. 2, so that the combination of the soft synthetic resin yarn and the hard synthetic resin monofilament yarn having opposite characteristics of the yarn Even if the net fabric is formed, there is an advantage that the unwinding and tissue deformation during use.

The net fabric 50 of the present invention manufactured as described above is wound in the direction of the soft synthetic resin yarn 20, as shown in FIG. It is closely wound on and wound up.

In addition, the net fabric is formed with a pattern portion 40 for decoration, as shown in Figure 4, the pattern portion 40 is a soft synthetic resin yarn (20) by pressing the fabric using a pattern of the desired pattern shape ) And the hard synthetic resin monofilament yarn 30 is pressed.

On the other hand, the net fabric is a metal nano-coating layer is formed on one surface, a soft transparent coating layer is formed as a whole so that the opening is not blocked in the net fabric on which the metal nano-coating layer is formed, one side (inside) is black and the other side (outside) is It has a color by the metal nano coating layer.

The metal nano coating layer may be implemented by vacuum deposition, e.g., evaporation, sputtering, ion plate, carbon nanotube, electroless plating, etc. Poration) can make the film thickness thicker and more suitable.

The metal used for the metal nano coating layer may be selected from aluminum (Al), stainless steel (Sus), chromium (Cr), copper (Cu), silver (Ag), titanium (Ti), and nickel (Ni). Aluminum is most suitable because it has the best gloss effect, and the deposition thickness is 0.01 μm to 1 μm.

In addition, since the soft transparent coating layer of the net on which the metal nano-coating layer is formed should not block the opening of the net, the dipping method in which the coating solution blocks the opening of the net or the coating is irregularly formed is not suitable, and the spray coating method is the most suitable method. Double sided coating is more effective than single sided coating of the net.

Such soft transparent coating layer forming materials include silicone, acrylic, epoxy, enamel, urethane, fluorine and PVC transparent coatings, and serve to protect the metal deposition surface from sun, acid and basic materials.

In addition, it should be used as a soft coating rather than a hard coating, because the protective coating is broken in the case of the hard coating when rolling, transporting, handling of the net fabric deteriorates the protective effect.

In order to satisfy all these conditions, the silicone-based coating solution is most suitable, and the coating film thickness is 1 to 100 μm, and it is more effective to coat the coating repeatedly after drying several times than thickening at once.

In addition, in order to improve the durability of the metal nano-coating layer, by applying a polyurethane-based resin to the net surface made of monofilament yarns and proceeding the metal nano-coating after the surface modification treatment, the durability is greatly improved, the surface using ultraviolet (UV) in this process If the reforming process is performed once more, the durability of the metal nano coating layer is improved exponentially.

The UV surface modification treatment is a principle of increasing hydrophilicity by increasing the polarity of the surface by cleaving a chemical bond by the ozone generated by applying a short-wavelength ultraviolet light with strong energy to generate carbonyl, carboxyl, hydroxyl, etc., The surface can be modified without impacting the product at a relatively low cost without affecting heat, and the monofilament net surface is modified to increase hydrophilicity, thereby improving the durability of the metal nano coating layer exponentially and increasing the durability of the monofilament and metal nano. Integration of the coating can be achieved.

In order to improve the durability of the metal nano coating layer, in addition to the above-described UV surface modification treatment, methods such as corona discharge treatment and plasma treatment may be used, but these methods may have UV surface in terms of practical aspects such as high installation cost, high treatment cost, and high surface damage. Less advantage than reforming.

The durability test results for pretreatment and UV pretreatment using these polyurethane-based resins are as follows.

First of all, when only the polyurethane-based resin was treated, the metal nano coating, that is, aluminum (Al) vacuum deposition and protective coating, showed a durability maintenance time of 65 to 75 hours, and the durability test was immersed in a strong acid of PH 3 or higher. At the same time, the light source is irradiated and tested under severe conditions. The light source uses four times stronger xenon arc than natural ultraviolet light, which uses the xenon arc method.

The surface of the monofilament net cross section was treated with low pressure UV (around 250 nm) and then subjected to Al vacuum deposition and protective coating after surface modification, and the durability test was performed in the same manner as described above. .

In Table 1, the UV irradiation time exceeds 60 seconds, it can be seen that the improvement of durability is no longer achieved, and showed a similar durability effect to the pretreatment with a polyurethane resin.

After the surface treatment of the polyurethane-based coating agent on the monofilament net cross-section surface, the surface was modified through low pressure UV (around 250 nm) irradiation, and then subjected to Al vacuum deposition and protective coating. One result is shown in Table 2.

As can be seen from Table 2, when both surface modification and UV surface modification using the polyurethane-based coating agent are performed, it can be seen that there is a synergy effect more than twice that of each carried out, and the durability is improved since the UV irradiation time exceeds 60 seconds. It can be seen that is no longer made.

In the above embodiment, a synthetic resin yarn of a ramp is used, and a synthetic synthetic monofilament yarn of a weft is used. However, when the winding direction of the net fabric is a weft direction, the synthetic yarn of a soft yarn is used, and the warp is a rigid yarn. Synthetic resin monofilament yarn may be used.
