Description

The present invention relates to a method for producing a laminated paper yarn and a laminated paper yarn produced by the method,

More particularly, the present invention relates to a method for producing a composite yarn, and more particularly, to a method for producing a composite yarn having excellent dyability and slitting processability by mutually laminating films made of materials having different processing characteristics The present invention relates to a method for manufacturing a composite yarn in which slitted composite yarns are spun in the form of a reinforcing yarn to increase durability and a composite yarn produced by the method.

Since the dyeing property, the slitting property and the durability are different from each other according to the material of the film used for the production of the yarn through the slitting process, it is possible to use polyethylene terephthalate (PET), nylon, aluminum, , And artificial inscriptions were used as yarn materials.

However, in the case of PET and nylon, it is possible to cut to a very narrow width due to the characteristics of moderate strength and flexible material, so that it is excellent in slitting workability, but has insufficient dyeing property and is limited in production of yarn of desired color, It was troublesome.

Particularly, it has been possible to produce metallic yarns such as silver yarn by slitting an aluminum evaporated film obtained by vacuum-depositing fine powder aluminum on a polyester film. However, since the aluminum vacuum deposited film is weak in temperature of post-dyeing and water dyeing, And the color on the printed surface is liable to be discolored.

On the other hand, in the case of paper or non-woven fabric materials, the dyeing properties were superior to those of the above-mentioned other materials, so that it was easily processed into a desired color. However, when the material is soft and less than a certain width, fine slitting processing is limited, There was a problem.

Further, in the case of the Korean paper material, it is widely used in the fiber system because it can visually and sensually feel the natural fiber. However, since the material is soft and the slitting process is limited as described above, .

3 is a cross-sectional side view showing the shape of a combine yarn fabricated by the method of making a combing yarn according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately The present invention should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

A method of manufacturing a jojun yarn according to a preferred embodiment of the present invention includes a first film 10 formed of PET (polyethylene terephthalate), a nylon material or aluminum deposited thereon, and a second film made of paper, paper, 30, which are made of materials having different processing characteristics, are slit together in a state in which they are mutually lapped, and are then fired in the form of a reinforcing fiber to produce a composite yarn having excellent dyeability, slitting processability and durability The first film supplying step S210, the adhesive applying step S220, the adhesive drying step S230, the second film supplying step S240, the lapping step S250, the slitting step S260) and a twisting step S270.

First, the first film supplying step (S210) is a step of supplying a first film (10) serving as a base of a laminating yarn, and a first film (10) made of PET or nylon, The first film feed roll 310 is rotated to feed the first film 10 to the rear end.

Here, when the aluminum is deposited, fine aluminum powder may be vacuum-deposited on the transparent base film such as a polyester film to form aluminum. In this case, since the base film is transparent, the aluminum color is transmitted to the other side even if aluminum is deposited only on one side, so that aluminum can be deposited on both sides.

2, the feeding direction of the first film 10 supplied to the first film supply roll 310 at a position spaced apart from the first film supply roll 310 in the direction in which the first film 10 is fed is switched The support rollers 323 for applying a predetermined amount of the adhesive 20 to the laminate can be applied while the first roll film 320 and the first film 10 described below are linearly contacted with each other in a partially abutting manner.

The adhesive 20 applied to the first film 10 by the rotation of the application roll 320 is adhered to each embossment 321 placed on the outer surface of the application roll 320 The application amount of the adhesive 20 to be applied to the first film 10 can be adjusted to be kept constant and can be compared with the adhesive injection method So that the injection nozzle is blocked due to the continuous injection, thereby solving the problem of maintenance.

Meanwhile, in the adhesive applying step (S220), a polyurethane adhesive excellent in adhesiveness and heat resistance can be used.

More specifically, the polyurethane adhesive that can be used in the present invention can be composed of the main adhesive component (a) and the crosslinking component (b). The main adhesive component (a) is obtained by reacting an isocyanate compound, a polyester polyol having a molecular weight of 400 to 4000, a polypropylene glycol having a molecular weight of 400 to 3000 and a chain extender, And diluted with a solvent.

Examples of the isocyanate compound used in the present invention include diphenyl-4,4'-methane diisocyanate, hexamethylene diisocyanate, and tolylidine diisocyanate, and one or more of them may be selected and used.

Here, the polyester polyol used in the present invention preferably has a molecular weight of 400 to 4000, more preferably at least one acid selected from the group consisting of adipic acid, isopropic acid and sebacic acid, , 1,4-butanediol, and neopentyl glycol. At this time, if the molecular weight of the polyester polyol is less than 400, it is too hard after the elapse of time, and if the molecular weight exceeds 4000, the polyester polyol proceeds to a necessary amount of polymer and the bonding strength is lowered.

The molecular weight of the polypropylene glycol used in the present invention is preferably from 400 to 3,000, and if the molecular weight is less than 400, the polypropylene glycol is too hard after the elapse of time. If the molecular weight exceeds 3000,

Examples of the chain extender used in the present invention include ethylene glycol, 1,4-butanediol, and trimethylolpropane, and one or more of them may be selected.

The main adhesive component (a) of the polyurethane adhesive is prepared by controlling the content of each component so that the molar ratio of the alcohol group in the polyol, glycol and chain extender to the isocyanate group of the isocyanate compound is 1: 1.1 to 2.0, Reacting at a temperature of 60 to 100 캜 with care, and then diluting with an organic solvent so that the non-volatile content is 30 to 70% by weight. Examples of the organic solvent usable herein include ethyl acetate, methyl ethyl ketone, and toluene, but are not limited thereto.

On the other hand, the molar ratio of the alcohol group in the polyol, the glycol and the chain extender to the isocyanate group of the isocyanate compound is preferably from 1: 1.1 to 2.0, and if the molar ratio is less than 1.1, the polymer is too polymerized, When it is more than 2.0, the molecular weight becomes low and the adhesive force is remarkably decreased.

The crosslinking component (b) of the polyurethane adhesive according to the present invention is obtained by reacting at least one alcohol selected from trimethylolpropane, ethylene glycol and 1,4-butanediol with an isocyanate compound in a molar ratio of 1: 2 to 4, And then diluted with an organic solvent such that the non-volatile content is 50 to 80% by weight. The isocyanate compound and the organic solvent used at this time are as described above.

On the other hand, the molar ratio of the alcohol to the isocyanate compound is preferably 1: 2 to 4, and if the molar ratio is less than 2, there is a danger of gelation due to a high molecular weight. If the molar ratio is more than 4, Or the bonding strength is lowered.

Since the polyurethane adhesive has excellent heat resistance, the polyurethane adhesive is applied to the aluminum vacuum deposition surface to eliminate desorption or discoloration / discoloration due to the high temperature post-exposure process and the conventional coating and printing process is omitted. A polyester aluminum vacuum vapor-deposited film and a polyester transparent base film are laminated to produce polyester metallic yarn of 0.18 mm to 5 mm or more.
