Technical Field [0001] The present invention relates to a metallic yarn using nylon film and a method for manufacturing the metallic yarn,

TECHNICAL FIELD The present invention relates to a metallic yarn using a nylon film and a method for producing the metallic yarn, and more particularly, to a metallic yarn using a nylon film applicable to dyeing nylon and a method for producing the same.

Metallic yarn, which exhibits metallic specific luster, is used for imparting decorative and aesthetic properties to textile products such as clothes, curtains, ornaments and the like, and is made of a metal such as aluminum, gold or silver on the surface of a synthetic resin film A metal deposition layer is formed by vapor deposition to form a metal deposition layer, and an antioxidant coating film made of a thermosetting resin such as acrylic resin is coated on the surface of the metal deposition layer to prepare a film. Then, the film is thinned using a cutter such as a slitter Width. The metallic yarn thus produced may be referred to as a "gold silver yarn" because it exhibits a metallic hue with shine such as gold or silver depending on the material of the metal deposition layer and the color of the anti-oxidation coating film. Typically, the metallic yarns are used in the manufacture of fabrics by yarns with common yarns such as polyester, nylon, cotton, rayon, and the like, and also, in order to dye the fabrics in a desired color, It is also used by dyeing with dye.

Conventionally, a polyester (PET) film was used to produce metallic yarns capable of dyeing fabrics, and a laminating method was introduced into the process line. FIG. 1 is a cross-sectional view of a metallic yarn used in a conventional artificial post-fading method. Referring to FIG. 1, a typical method for producing a metallic yarn will be described. First, a coating agent containing an epoxy melamine resin as a main component is diluted (Protective coating resin 10) was prepared by gravure roll coating method and aluminum deposition (AL) deposition film 12 having a thickness of 6 to 6.8 micron (탆) And then the coating film is thermally cured by passing through a drying furnace to coat the film. (b) The coated film is put on a first feeding roll, and the adhesive 14 is applied on the protective coating resin film of the coating film using a gravure roll coating method, and then passed through a drying furnace to remove the diluting solvent Evaporated and laminated with a 6 to 6.8 micron thick polyester film (PET base film, 16a, 16b) on a second paper feed roll located on the opposite side to produce a laminated film. (c) When a film having the structure as shown in Fig. 1 is produced, it is cut with a micro-slitter machine to produce a metallic yarn having a metallic luster on its surface. The metallic yarn thus produced is made of polyester, nylon, It is used in the manufacture of fabrics by yarns (yarns) in various ways.

However, when the metallic yarn is produced in the above-described manner, since the material of the film, which is the main material of the product, is polyester, the acid dye used in nylon dyeing is not dyed (dyed) onto the surface of the metallic yarn , There is a problem that it can not be used in the actual nylon backfill method. In order to overcome the disadvantages of such a polyester film, nylon film has excellent durability and flexibility compared with polyester film, soft touch due to soft material, Is widely used, but it is difficult to produce metallic yarn due to the characteristics of a nylon film which is weak to heat, hygroscopic and easily deformed or susceptible to damage during dyeing.

An object of the present invention is to provide a metallic yarn using a nylon film capable of nylon dyeing and a method for producing the same.

Another object of the present invention is to provide a metallic yarn using nylon film which can prevent or minimize the damage of the metal deposition layer by forming a primer coating layer and / or a moisture inflow preventing layer which blocks or minimizes the inflow of moisture into the nylon film and And a manufacturing method thereof.

It is another object of the present invention to provide a metallic yarn using a nylon film and a method for producing the same, which can reduce nylon dyeing in a conventional post dyeing process as well as a conventional post dyeing process, .

In order to achieve the above object, the present invention provides a nylon film having excellent durability and flexibility on one side thereof, a primer for preventing damage to the following metal deposition layer by moisture, and an adhesive force between the nylon film and the following metal deposition layer Forming a coating layer; Depositing a metal on the primer coating layer to form a lustrous metal deposition layer; And forming a metal protective layer on the metal vapor deposition layer to prevent moisture from entering the metal vapor deposition layer and preventing damage to the metal vapor deposition layer, followed by aging and cutting the metal protective layer. The method for producing a metallic yarn using a nylon film .

The present invention also provides a nylon film excellent in dyability and flexibility; A primer coating layer formed on one side of the nylon film to prevent damage to the following metal deposition layer by moisture and to improve adhesion between the nylon film and the metal deposition layer; A lustrous metal deposition layer deposited on the primer coating layer; And a metal protective layer formed on the metal deposition layer to prevent moisture from entering the metal deposition layer to prevent damage to the metal deposition layer.

According to the metallic yarn using the nylon film according to the present invention and the manufacturing method thereof, the adhesion of the nylon film and the metal deposition layer can be improved by forming the primer coating layer between the nylon film and the metal deposition layer. In addition, the primer coating layer and the moisture inflow preventing layer can block or minimize the inflow of moisture, and in particular, even if the internal physical properties of the nylon film are changed by the high temperature water, the metal vapor deposition layer is not directly affected , It is possible to prevent or minimize the damage of the metal deposition layer in the inside of the film, thereby maintaining the metallic luster inherent to the metallic yarn. Therefore, it is possible to dye nylon even in post-processing (a method of dyeing in the state of fabric (fabric), not in the state of yarn), and ultimately it is possible to reduce the cost of the dyeing process.

5 is a view illustrating a process of producing a metallic yarn using a nylon film according to another embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As described in the background art, the application of a nylon film to a metallic yarn has many advantages compared to a conventional polyethylene (PET) film. However, due to some limitations, Use is limited. Therefore, it is necessary to develop a metallic yarn applicable to nylon dyeing by grasping the limitations of the nylon film and modifying the manufacturing method of the metallic yarn. As a solution thereof, the following three approaches are proposed.

(A) Removing or minimizing hygroscopicity of nylon film

Unlike the polyester film, the nylon film has a property of changing its physical properties by absorbing moisture. When moisture is introduced into the nylon-deposited film, the adhesion between the film and the metal sharply decreases. Especially, in a high- There arises a problem that the metal reacts with water (in particular, high-temperature water) to damage the metal deposition layer. For a more detailed description, for example,

(i) A 12-micron thick polyester film and a nylon film each having a metal, for example, aluminum deposited thereon, were immersed in normal temperature water at 25 ° C for 3 hours and then observed for changes. As a result, The aluminum deposited layer on the nylon film was damaged by about 70% while the damaged aluminum layer was flaked on the surface of the water while the deposited aluminum layer was not damaged at all there was.

(ii) On the other hand, when the two samples of (i) were immersed in boiling water of 100 ° C instead of 25 ° C of the hot water, all of the aluminum deposition layers deposited on the polyester film and the nylon film completely disappeared However, it was not possible to visually confirm damaged aluminum on the surface of the water or in the water.

The results of experiments (i) and (ii) show that aluminum itself does not react with low temperature water, but rapidly reacts with high temperature water. In addition, although the aluminum deposited on the nylon film falls off in a flake form, even though it is immersed in low-temperature water, the inside of the nylon film is deformed due to the influx of moisture, It was found that the aluminum deposition layer was peeled off.

Next, an experiment was conducted as follows to observe how the moisture was introduced into the portion of the film.

(iii) FIGS. 2 and 3 are cross-sectional views of a film produced to observe the moisture inflow path into the nylon film. FIG. 2 shows a nylon film 22 having a thickness of 12 microns on which aluminum 20 is deposited, Is a cross-sectional view of a 12-micron thick nylon base film (24) laminated with a two-component polyurethane adhesive (26) so that the laminated film is immersed in boiling water at 100 ° C And the change was observed. As a result, the aluminum deposition layer 20 completely disappeared in about 5 minutes.

(iv) FIG. 3 is a cross-sectional view of a film in which a protective resin layer (or a protective coating layer, 28a, 28b) is further coated on the outermost sides of the laminated film (FIG. 2), and the protective resin layers 28a, 28b ) Of the aluminum deposition layer 20 was immersed in boiling water at 100 캜 and observed for changes. As a result, about 80% of the aluminum deposition layer 20 was preserved even after 30 minutes passed.

It can be seen from the results of Experiments (iii) and (iv) that the inflow of moisture mainly consists of a portion where the film and the water are directly in contact with each other. Therefore, the outer surface of the film, 28b, it is possible to prevent the moisture from entering the nylon film and to prevent the loss of the aluminum deposition layer 20 deposited on the nylon film.

(B) Strengthening adhesion between films during laminating

As shown in FIGS. 2 and 3, a nylon film on which a metal is deposited and a corona-free nylon film on which corona treatment has been performed are laminated to produce a film to be applied to a metallic yarn, The nylon film on which the metal is deposited and the corona-treated nylon base film after the dyeing peel off from each other. To prevent this, a two-component polyurethane adhesive for a retort pouch having enhanced heat resistance may be used.

(C) Prevention of damage to metal vapor deposition

In general nylon dyeing, when the nylon film is immersed in a dyeing bath, deformation occurs inside the film due to the high water temperature, the enclosed pressure inside the film and the influx of moisture into the film. As a result, the adhesive force between the nylon film and the metal deposition layer is weakened, and the metal layer reacts with the influxed moisture to cause damage to the metal deposition layer. In order to prevent this, a conventional method of directly depositing a metal on the surface of a nylon film can be modified. First, a primer action (an action for enhancing adhesion with a nylon film surface) is applied to the surface of the nylon film, After forming a primer coating layer capable of blocking possible moisture, a metal was deposited on the primer coating layer. As a result, the metal is deposited on the primer coating layer to maximize the bonding force, and the damage of the metal deposition layer is prevented or minimized.

4 is a view showing a process of producing a metallic yarn using a nylon film according to an embodiment of the present invention. Referring to FIG. 4, a method of producing a metallic yarn using the nylon film according to the present invention will be described.

First, as shown in Fig. 4A, damage to the following metal deposition layer caused by moisture (water, particularly, high-temperature water) is prevented on one side of the nylon film 100 having excellent dyeability and flexibility, A primer coating layer 120 for improving the adhesion between the metal deposition layer 100 and the metal deposition layer described below is formed.

The nylon film 100 is a base material for imparting physical properties such as rigidity and tensile strength of a metallic yarn as fibers and is a film containing nylon which is a common polyamide synthetic fiber. The inner surface of the nylon may be a corona-treated film. The nylon film 100 is widely used in various fields such as clothes, foods, and industrial packaging materials based on excellent rigidity, tensile strength, stability and processability, and the thickness and width of the nylon film used in the present invention , A thickness of 5 to 100 microns, preferably 10 to 50 microns, more preferably 10 to 20 microns, and a thickness of 0.1 to 5 mm, preferably 0.2 to 3 mm, mm, more preferably 0.3 to 1 mm. The length of the nylon film 100 may also be cut to an appropriate length if necessary.

As described above, when the nylon film 100 is immersed in hot water, the primer coating layer 120 deforms inside the film due to the influx of moisture into the film. As a result, the nylon film 100 The adhesion between the metal vapor deposition layer 130 and the metal vapor deposition layer 130 is weakened to prevent damage to the metal vapor deposition layer 130 caused by reaction of the introduced moisture and the metal. Here, the term 'high temperature' means about 50 ° C or higher, preferably 70 ° C or higher, more preferably 100 ° C or higher.

If the nylon film 100 and the metal deposition layer 130 can be adhered to the primer coating layer 120 while preventing the moisture from flowing in the direction of the nylon film 100, The use of a resin solution containing a modified phenolic resin and a solvent capable of dissolving the modified phenolic resin may be most advantageous. The modified phenolic resin preferably has a viscosity (cps / 25 ° C) of 50 or less and a solid content of 10 to 15% by weight. Instead of the modified phenolic resin, a vinyl acetate resin or an acrylic resin may be used. As the solvent, a conventional solvent capable of uniformly dissolving the resin can be used without particular limitation. Examples of the solvent include ethyl acetate, methyl ethyl ketone (MEK), toluene, acetone, alcohol (methanol, ethanol, propanol , Butanol, etc.) may be used singly or in combination. On the other hand, a thermosetting resin such as an epoxy resin or a melamine resin can also be used, but it is preferable to avoid use as much as possible because the film may be deformed due to a high curing temperature of the resin.

In the resin liquid, the content of the resin is 30 to 70 parts by weight, preferably 40 to 60 parts by weight, more preferably 45 to 55 parts by weight, relative to 100 parts by weight of the total resin liquid, As the solvent, it is preferable to mix the resin and the solvent at a weight ratio of about 1: 1. If the amount of the resin and solvent used is too large or too small, the primer coating layer 120 may be formed unevenly or may take an excessive amount of time and energy. The weight average molecular weight of the resin is about 100 to 20,000, preferably 300 to 10,000. The resin solution used as the primer coating layer 120 may further include a curing agent and a plasticizer as necessary in order to improve the intermolecular binding force of the resin and improve the flexibility of the primer coating layer 120 have.

The resin liquid used as the primer coating layer 120 may be coated on the nylon film 100 by a conventional coating method such as a gravure roll coating method, a reverse coating method, And dried by heating and drying (that is, drying and removal of the solvent) to form the primer coating layer 120. The temperature of the heat drying step is usually 50 to 150 ° C, preferably 55 to 120 ° C, more preferably 60 to 90 ° C, and the drying time may vary depending on the drying temperature, but is preferably 3 seconds to 2 minutes To 10 seconds to 1 minute, and the coating line speed may be about 60 to 80 m / min. If the drying temperature and time are too low, there is a risk that the resin is not sufficiently cured due to insufficient drying. If the drying temperature and time are too long, the nylon film 100 may be shrunk by heat .

Next, as shown in FIG. 4B, a metal is deposited on the primer coating layer 120 to form a glossy metal deposition layer 130.

On the other hand, metallic colors can also be expressed using the unique colors of the metals. The thickness of the metal deposition layer 130 may be appropriately adjusted in consideration of the degree of metallic color development, the characteristics of the metallic yarn fiber, the manufacturing cost, and the like. For example, the thickness may be 50 to 2,000 angstroms 100 to 1,000 angstroms, more preferably 300 to 700 angstroms. In addition, the deposition of the metal may be performed by a conventional metal deposition method such as a sputtering type, an E-BEAM type, and an EVA type.

Finally, as shown in FIG. 4C, a metal protection layer 132 is formed on the metal deposition layer 130 to prevent moisture from entering the metal deposition layer 130 to prevent damage to the metal deposition layer 130 The metal deposition layer 130 is prevented from being damaged in both directions, as shown in FIG. 4D, by performing the aging and cutting processes, .

The metal protective layer 132 prevents moisture from flowing in the opposite direction of the nylon film 100, that is, the direction in which the metal protective layer 132 is formed, And adhesion force for bonding with the metal deposition layer 130 should also be included. The metal protective layer 132 may be formed by coating, heating and drying a resin solution containing a modified vinyl resin and a solvent capable of dissolving the modified vinyl resin, and removing the solvent. The modified vinyl resin has a viscosity cps / 25 占 폚) of not more than 50 and a solid content of 14 to 16% by weight. Instead of the modified vinyl resin, a urethane resin or an acrylic resin may be used. As the solvent, a conventional solvent capable of uniformly dissolving the resin can be used without particular limitation. Examples of the solvent include ethyl acetate, methyl ethyl ketone (MEK), toluene, acetone, alcohol (methanol, ethanol, propanol , Butanol, etc.) may be used singly or in combination.

In the resin solution, the content of the resin is 20 to 60 parts by weight, preferably 30 to 50 parts by weight, more preferably 35 to 45 parts by weight, relative to 100 parts by weight of the total resin solution, As the solvent, it is preferable to mix the resin and the solvent at a weight ratio of about 4: 6. If the amount of the resin and the solvent used is too large or too small, the metal protective layer 132 may be formed unevenly or may take an excessive amount of time and energy. The weight average molecular weight of the resin is about 100 to 20,000, preferably 300 to 10,000. The resin liquid used as the metal protective layer 132 may further include a curing agent and a plasticizer as necessary in order to improve the intermolecular binding force of the resin and improve the flexibility of the metal protective layer 132 can do.

The resin solution used as the metal protective layer 132 may be coated on the metal deposition layer 130 by a conventional coating method such as a gravure roll coating method, a reverse coating method, or a spraying method, That is, the solvent is dried and removed) to form the metal protective layer 132. The temperature of the heat drying step is usually 50 to 150 ° C, preferably 55 to 120 ° C, more preferably 60 to 90 ° C, and the drying time may vary depending on the drying temperature, but is preferably 3 seconds to 2 minutes 10 seconds to 1 minute, and the coating line speed may be about 80 to 100 m / min. If the drying temperature and time are too low, there is a risk that the resin is not sufficiently cured due to insufficient drying. If the drying temperature and time are too long, the nylon film 100 may be shrunk by heat .

When the metal protective layer 132 is coated on the metal deposition layer 130, the metal protective layer 130 is coated on the metal deposition layer 130 at a temperature of 50 to 150 캜, preferably 55 to 120 캜, more preferably 60 to 90 캜 for 3 seconds to 2 minutes, (Micro-slit, cut into a thin width) of 0.3 to 2 mm in width using a conventional apparatus such as a slitter after drying (aging) for 10 seconds to 1 minute, preferably 10 seconds to 1 minute , The metallic yarn can be produced.
