Description

Functional polyester fiber having excellent antibiotic property, and radiating far-infrared ray and anion

The present invention relates to a polyester fiber that emits antimicrobial activity and far infrared rays and anions, and more particularly, to a metal fiber having an antimicrobial activity and a ceramic powder that emits far infrared rays and anions uniformly dispersed in a polyester polymer and to the mixed spinning method It is to provide a functional polyester fiber having antimicrobial properties and properties of emitting far infrared rays and anions produced by the.

As the standard of living improves recently, the desire of consumers to pursue a more comfortable life is increasing, and the functional polyester fiber that emits antimicrobial and far-infrared rays and anions developed in response to this is parasitic on fibers and causes various diseases and odors. To ensure a comfortable life by removing various microorganisms, the demand for them has exploded with the recent diversification of their use.

Conventional antibacterial deodorizing fibers have been prepared by coating silicone fibers with quaternary ammonium salts by post processing.

For example, Japanese Patent Publication No. 87-184126, which is an antibacterial and deodorizing technique using quaternary ammonium salts, 88-152473, etc., which is applied to a polyester / cotton blend using a processing agent having a quaternary ammonium salt, anionic 84-112070, which is a polyamide fiber treated with a phenol compound, and US Pat. No. 4,701,518, which is a method for producing antimicrobial polyester fiber treated with a zinc compound. The antimicrobial deodorant fiber by these methods has a problem of deterioration of washing resistance, which is an absolute weakness of the human harmfulness and post-processing of the quaternary ammonium salt added for the expression of antimicrobial properties.

In addition, Japanese Patent Application Laid-Open No. 59-134418, Japanese Patent Laid-Open No. 61-17567, Korean Patent Publication No. 95-018915, etc., prepared a liquid composition by mixing a ceramic antimicrobial agent with a polyurethane resin and a surfactant, The technique of spraying on the surface of the fiber to make the inorganic ceramic particles adhere to the surface has been introduced, but the polyester fiber products produced in this way has the disadvantage that the functionality is not permanent due to the problem of washing resistance.

In addition, in order to alleviate such disadvantages, a method of dispersing inorganic zeolites substituted with antimicrobial metals into fibers by using a master batch method or using ceramics is disclosed in Japanese Patent Application Laid-Open No. 61-234390. , Japanese Patent Application Laid-Open No. 62-101643, etc., but this technique can improve the washing resistance of functional textile products, but due to the hygroscopic zeolite, there is a problem of frequent trimming and discoloration of the textile products during melt spinning. In the dyeing process leads to poor dyeing, there are many problems in the actual fiberization.

Therefore, the present invention has been made to solve the problems described above, in the production of functional fiber products, without the problems occurring in the production process such as laundry resistance, spinning processability, processing processability, far-infrared and anion emission It is an object of the present invention to provide a method for producing a functional polyester fiber capable of expressing functions such as resistance, antimicrobial activity, and deodorization.

The present invention is to mix and spin so that at least one ceramic powder selected from Structural Formula (1), Structural Formula (2), or Structural Formula (3) which emits far-infrared rays and emits anions to the polyester polymer so as to have a content of 0.1 to 5% by weight. It features.

[Structure Formula (1)]

X ₁ Y ₃ Al ₆ B ₃ Si ₆ (OH) ₄

X = Na and / or Ca, Y = Mg, Li, Al, and / or Fe ²⁺

(Al and OH are substituted with other)

[Structure Formula (2)]

(Na, Ca) ₂ (Al ₂ Si ₃ O ₁₀ ) 8H ₂ O

(Including derivatives of these compounds)

[Structure Formula (3)]

(Ce, La, Th, Nd, Y) PO ₄

(Including derivatives of these compounds)

In addition, the present invention provides a ceramic powder of the above formulas (1) and (3) that emits far infrared rays and emits anions to the polyester polymer in a weight ratio of 1:99 to 99: 1, preferably 30:70 to 70: It is characterized by using a mixture of 30.

In addition, the present invention is characterized in that the spinning is mixed with a metal inorganic ceramic containing silver to 0.01 to 5.0% by weight in order to give antimicrobial properties to the polyester polymer.

The antimicrobial metal powders used in the present invention are silver (Ag), copper (Cu), zinc (Zn) nickel (Ni), and the like, and these metal elements have a selectivity for acting on microorganisms.

In the present invention, it is preferable to use a combination of the metal powders well, because when a certain element is large, the antimicrobial property tends to decrease and the color unique to the metal component is expressed.

In the present invention, the metal powders are bonded in the form of ions such as silver (Ag), copper (Cu), zinc (Zn), nickel (Ni), etc., which are metal ions having an antimicrobial activity by using a zeolite, which is an inorganic ceramic material, as a carrier. It is used in the form of a metal inorganic antimicrobial agent, wherein the input amount is characterized in that the content of the metal inorganic antimicrobial agent to 0.01 to 5.0% by weight of the polyester polymer weight. If the content of the metal inorganic antimicrobial agent is less than 0.01% by weight, the antimicrobial properties of the polyester is lowered, and if the content is more than 5.0% by weight, not only economical disadvantages but also radioactivity is poor.

In addition, in the present invention, the ceramics represented by the chemical formulas (1), (2) and (3), which emit the far infrared rays and emit the anions, are characterized in that the fiber is mixed and spun to 0.1 to 5% by weight. If the content of the ceramics represented by the chemical formulas (1), (2) and (3) is less than 0.1% by weight, the far-infrared rays of the polyester are radiated and the anions are not released. It also loses radioactivity.

Particularly, in the present invention, the ceramic powder of Structural Formula (1) and Structural Formula (3) that emits far infrared rays and emits anions to the polyester polymer is 1:99 to 99: 1 by weight, preferably 30:70 to 70:30. It is characterized by using a mixture. It is remarkable when far infrared and anion are released when the ceramic powders of the formulas (1) and (3) are mixed.

In general, there is a problem that the physical properties of the fiber is lowered, in order to solve this, it is necessary to make the average particle size of the ceramic small and uniform.

In the present invention, in order to apply the metal inorganic antimicrobial agent or ceramic to the polyester fiber, the particle size is preferably 1 μm or less.

In the present invention, it is characterized in that it comprises a water-based grinding process to prepare a metal inorganic antimicrobial agent or ceramic with a particle size of 1 ㎛ or less suitable as an additive for producing synthetic fibers, the detailed process is as follows.

First, the inorganic metal antimicrobial agent or the original ceramic powder is ground in a water-based state with a steel ball mill having a diameter of 0.1 to 1 μm and then dried. Particles having a particle size of 1 µm or more among the pulverized and dried inorganic minerals are separated and regrind using a 1 µm mesh filter to maintain 90% and 1 µm or less of a ground powder slurry.

The average particle diameter of the metal inorganic antimicrobial agent or ceramic produced by the above method is about 0.29 μm, and particles having a size of 1 μm or more are suitable to be added to the polyester fiber by about 1 to 2%.

In the present invention, it is preferable to prepare the metal inorganic antimicrobial agent or ceramic fine particles of 1 μm or less and prepare them into an ethylene glycol slurry, and then add them to a conventional polymerization process of polyester, and add or mix the metal inorganic antimicrobial agent or ceramic fine particles, respectively. It can also be prepared and prepared at the same time.
