Definitions
- the present invention relates to a copolymerized aramid dope-dyed yarn and a method for preparing the same, and more particularly, to a method for preparing a copolymerized aramid dope-dyed yarn with excellent color strength and color fastness by mixing a coloring matter having a cation in a polymerization solution when spinning the polymerization solution containing a copolymerized aramid polymer by means of a spinning spinneret without using sulfuric acid.
- Aromatic polyamide commonly referred to as an aramid, includes a para-based aramid having a structure in which benzene rings are linked linearly through an amide group (—CONH) and a meta-based aramid which has a linkage structure different from the para-based aramid.
- the para-based aramid has excellent characteristics such as a high strength, high elasticity and low shrinkage. Since the para-based aramid has a high enough strength so as to be able to lift a two-ton vehicle with a thin cable made thereof having a thickness of about 5 mm, it is widely used for bulletproofing, as well as in a variety of applications in advanced industries of an aerospace field.
- the aramid is carbonized and becomes black at 500° C. or more, thus being also spotlighted in fields requiring high heat-resistant properties.
- aramid fiber The preparation method of aramid fiber has been explained well in Korean Patent Registration No. 10-0910537 owned by the present applicant.
- a mixture solution is prepared by dissolving aromatic diamine in a polymerization solvent, then, followed by adding aromatic diacid to the above solution to prepare an aramid polymer.
- the aramid polymer is dissolved in a sulfuric acid solvent to prepare a spin dope, the spin dope is spun, followed by conducting coagulation, washing and drying processes in this order, thereby finally completing an aramid fiber.
- the aramid fiber is prepared according to the above-described processes, an aramid polymer in a solid state is prepared and again dissolved in a sulfuric acid solvent to prepare a spin dope, followed by spinning the same. Therefore, a manufacturing process becomes complicated, is harmful for a human body, and may cause a problem such as a decrease in durability due to corrosion of an apparatus.
- Korean Patent Registration No. 10-171994 discloses a method for fabricating an aramid fiber directly using a copolymerized aramid polymerization solution as a spin dope, thus not requiring a sulfuric acid solvent.
- a copolymerized aramid fiber is manufactured by adding terephthaloyl dichloride to an organic solvent in which para-phenylenediamine and cyano-para-phenylenediamine are dissolved, and reacting the same to prepare a polymerization solution containing a copolymerized aramid polymer, then, spinning and coagulating the polymerization solution.
- the conventional art entails a problem that the prepared copolymerized aramid fiber has deteriorated dyeing property due to high crystalline property although having an advantage of not using the sulfuric acid solvent.
- Korean Patent Registration No. 10-067338 discloses a method for fabricating a copolymerized aramid fiber that includes adding polyvinyl pyrrolidone as a non-crystalline polymer to a polymerization solution when the copolymerized aramid fiber is manufactured by adding terephthaloyl dichloride to an organic solvent in which paraphenylenediamine and cyano-para-phenylenediamine are dissolved, and reacting the same to polymerize the polymerization solution containing a copolymerized aramid polymer, then, spinning and coagulating the same.
- this method involves problems of deteriorating solubility and dyeing fastness of the polymerization solution although improving dyeing property of the manufactured copolymerized aramid fiber.
- a fabrication method of a copolymerized aramid dope-dyed yarn including addition of a specific coloring matter which may not be bonded to a cyano group (-CN) of the copolymerized aramid through a hydrogen bond, that is, a coloring matter which does not contain a cation, when a copolymerized aramid fiber is prepared by adding terephthaloyl dichloride to an organic solvent in which para-phenylenediamine and cyano-para-phenylenediamine are dissolved, and reacting the same to polymerize a polymerization solution containing a copolymerized aramid polymer, then, spinning and coagulating the polymerization solution.
- a specific coloring matter which may not be bonded to a cyano group (-CN) of the copolymerized aramid through a hydrogen bond
- a coloring matter which does not contain a cation when a copolymerized aramid fiber is prepared by adding terephthalo
- this method entails some problems such as a decrease in a polymerization degree of the copolymerized aramid polymer, a reduction in solubility of the polymerization solution, and a deterioration in a color fastness of the manufactured dope-dyed yarn.
- An object of the present invention is to provide a copolymerized aramid dope-dyed yarn with excellent color strength and color fastness, and a method for preparing the same while preventing a decrease in a polymerization degree of copolymerized aramid and a reduction in solubility of a polymerization solution.
- the present invention provides a method for preparing a copolymerized aramid yarn, including adding a coloring matter having cations in an amount of 0.1 to 5% by weight (‘wt. %’) to a weight of a copolymerized aramid polymer in a polymerization process of a polymerization solution containing the copolymerized aramid polymer, when the copolymerized aramid yarn is prepared by adding terephthaloyl dichloride to an organic solvent in which an aromatic diamine having a cyano group is dissolved, reacting the same to polymerize the polymerization solution containing the copolymerized aramid polymer, then, spinning and coagulating the polymerization solution.
- wt. % a coloring matter having cations in an amount of 0.1 to 5% by weight
- the present invention due to the addition of the coloring matter to the polymerization solution, it is possible to efficiently prevent a decrease in a polymerization degree of the copolymerized aramid polymer or a reduction in solubility of the polymerization solution.
- the copolymerized aramid polymer having a cyano group (-CN) and the coloring matter having a cation are bonded through a hydrogen bond in the polymerization process of the polymerization solution containing the copolymerized aramid polymer, and the coloring matter having a cation is bonded with the cyano group (-CN) located on a main chain of the copolymerized aramid polymer through an ionic bond, and can show behavior together with the main chain during formation of a liquid crystal, thereby improving color strength, color fastness to light and color fastness to washing of the copolymerized aramid dope-dyed yarn.
- an inorganic salt is dissolved in an organic solvent, followed by adding aromatic diamine having a cyano group (CN-) thereto.
- the aromatic diamine having a cyano group may include a solution of paraphenylenediamine and cyano-para-phenylenediamine dissolved in a molar ratio of 1:9 to 9:1, or a solution of cyano-para-phenylenediamine alone.
- the organic solvent may include, for example,
- NMP N-methyl-2-pyrrolidone
- DMAc N,N-dimethylacetamide
- HMPA hexamethyl phosphoamide

- the inorganic salt is added in an amount of 2 to 5 wt. % to a weight of the organic solvent.
- terephthaloyl dichloride is added in the same molar amount as that of the aromatic diamine having a cyano group to the organic solvent containing aromatic diamine having a cyano group added and dissolved therein.
- the coloring matter having a cation is added to the organic solvent to prepare a polymerization solution containing a copolymerized aramid polymer.
- the coloring matter having a cation has the following representative structures, but it is not limited thereto.
- the coloring matter having a cation is added in an amount of 0.1 to 5 wt. % to a weight of the copolymerized aramid polymer. If the added amount is less than 0.1 wt. %, a color strength is weak, and if it exceeds 5 wt. %, physical properties of a fiber may be deteriorated.
- the cyano group (-CN) has strong electronegativity to thus exhibit a repulsive force from an anionic sulfone group of the coloring matter having an anion.
- the coloring matter having an anion could not be deposited on a polymer but be discharged along with the solvent, hence expressing a color in not a coloring level but a pollution level and having a considerably deterioration in the color strength, color fastness to light and color fastness to washing of the copolymerized aramid dope-dyed yarn.
- coloring matter having an anion examples are as follows.
- the copolymerized aramid dope-dyed yarn of the present invention may include any one of the above coloring matter having a cation alone or in combination of two or more thereof.
