본 발명은 의류용 원사, 특히 스포츠 의류용 원사로 사용시 인체에 유해한 균의 침투 및 증식을 억제하는 기능(이하 "항균성"이라고 한다)이 우수한 공기교락사(혼섬사)에 관한 것이다.The present invention relates to an air entangled yarn (honsum yarn) having an excellent function of inhibiting the penetration and propagation of bacteria harmful to the human body (hereinafter referred to as "antibacterial") when used as a yarn for clothing, especially a sports garment.

최근 생활수준이 향상됨에 따라 다양한 항균성을 구비한 의류의 수요가 확대되고 있다.As the standard of living improves recently, the demand for clothing with various antibacterial properties is expanding.

섬유에 항균성을 부여하기 위한 종래기술로서는 직물을 항균제 용액내에 침지하여 항균성을 부여하는 방법이 널리 사용되고 있으나, 이 경우 10회 이상 세탁 후에는 향균 기능이 상실되는, 즉 내세탁성이 낮은 문제가 있었다.As a conventional technique for imparting antimicrobial properties to fibers, a method of imparting antimicrobial properties by immersing the fabric in an antimicrobial solution is widely used, but in this case, the antibacterial function is lost after washing 10 times or more, that is, there is a problem of low washing resistance. .

섬유에 향균성을 부여하는 또 다른 종래기술로서는 섬유 소재인 고분자 수지에 항균 활성 물질을 포함하는 공중합 성분을 공중합시키는 방법과, 고분자 수지 내부에 미세 항균제를 블렌딩하는 방법 등도 사용되고 있다.As another conventional technique for imparting antimicrobial properties to fibers, a method of copolymerizing a copolymer component containing an antimicrobial active material into a polymer resin, which is a fiber material, a method of blending a fine antibacterial agent inside the polymer resin, and the like are also used.

항균제로는 키토산류 등과 같은 천연계 항균제나 은계 또는 광촉매 기능을 가지는 무기계 항균제가 사용되고 있으나 고온의 방사공정 중에 잘 견딜수 있는 무기계 항균제가 보다 널리 사용된다.As antibacterial agents, natural antibacterial agents such as chitosans, and inorganic antimicrobial agents having silver or photocatalyst functions are used, but inorganic antimicrobial agents that can withstand during high-temperature spinning processes are more widely used.

이상에서 살펴본 방법들은 섬유에 항균성을 부여할 수 있으나 내세탁성이 저조한 문제가 있었다.The methods discussed above can impart antimicrobial properties to the fiber but have poor laundry resistance.

본 발명의 목적은 이와같은 종래의 문제점들을 해결하기 위하여 항균성이 우 수함과 동시에 사염시 사층 붕괴를 효과적으로 방지할 수 있는 공기교락사를 제공하기 위한 것이다.
An object of the present invention is to provide an air entangled sand that can effectively prevent the four-layer collapse during the salt kill while at the same time excellent antimicrobial to solve these problems.

본 발명은 공기교락사를 구성하는 모노필라멘트 내에 인산지르코늄에 은(Ag)이 치환된 은계 무기항균제(직경 : 0.1 ~ 1.0㎛)를 분산, 함유시키므로서 조업성의 저하 없이도 공기교락사에 항균성을 부여하고자 한다.The present invention disperses and contains a silver-based inorganic antimicrobial agent (diameter: 0.1 to 1.0 μm) in which silver (Ag) is substituted in zirconium phosphate in the monofilament constituting the air entangled yarn, thereby providing antimicrobial activity to the air entangled yarn without deterioration in operability. I would like to.

아울러, 본 발명은 2개의 멀티필라멘트들을 공기교락 시키므로서 사염시 사층 붕괴를 효과적으로 방지하고자 한다.
In addition, the present invention is to effectively prevent the four-layer collapse during salting by air entanglement of the two multifilament.

이와같은 과제를 달성하기 위한 본 발명의 공기교락사는 (ⅰ)열가소성 수지의 모노필라멘트들로 구성된 2개의 멀티필라멘트들이 공기교락되어 80개/m 이상의 교락점을 형성하고 있으며, (ⅱ)평균 입자직경이 0.1㎛ ~ 1.0㎛이며, 무기담체인 인산지르코늄에 은(Ag)이 차환된 은계 무기항균제가 전체 원사 중량 대비 0.3 ~ 2.0중량% 함유되어 있고, (ⅲ)원사 상태로 염색되어 있는 것을 특징으로 한다.The air entangled yarn of the present invention for achieving the above object is (i) two multifilaments composed of monofilaments of thermoplastic resin are air entangled to form an entanglement point of 80 or more / m, (ii) the average particle diameter 0.1-1.0 micrometer, and the silver-based inorganic antimicrobial agent by which silver (Ag) was substituted in the zirconium phosphate which is an inorganic carrier contains 0.3-2.0 weight% with respect to the total yarn weight, and (i) is dyed in the yarn state. do.

이하, 본 발명을 도면 등을 통하여 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.

먼저 본 발명은 열가소성 수지의 모노필라멘트들로 구성된 멀티필라멘트 2개가 공기교락되어 있으며 사염처리된 공기교락사이다.First, the present invention is an air entangled and salt-treated air entangled two multifilaments composed of monofilaments of thermoplastic resin.

본 발명에 있어서, 열가소성 수지로는 폴리아미드, 폴리에스테르 또는 폴리 아크릴 등이 사용될 수 있으며, 더욱 바람직하기로는 소수성인 폴리에스테르를 사용하는 것이 좋다.In the present invention, as the thermoplastic resin, polyamide, polyester or polyacryl may be used, and more preferably, hydrophobic polyester is used.

본 발명의 공기교락사(원사)는 평균 입자직경이 0.1 ~ 1.0㎛인 은계 무기항균제를 전체 원사 중량 대비 0.3 ~ 2.0중량% 함유하고 있다.Air entangled yarn (yarn) of the present invention contains a silver-based inorganic antimicrobial agent having an average particle diameter of 0.1 ~ 1.0㎛ 0.3 ~ 2.0% by weight relative to the total yarn weight.

상기 은계 무기항균제는 무기담체인 인산지르코늄(ZrO2P2O5)에 은(Ag)이 치환된 항균제로서 일본회사인 동아합성주식회사(東亞合性株式會社)의 제품인 "NOVARON"(제품명)이다.The silver inorganic antibacterial agent is an antimicrobial agent in which silver (Ag) is substituted for zirconium phosphate (ZrO 2 P 2 O 5 ), which is an inorganic carrier, and is a product of "NOVARON" (product name) manufactured by Dong-A Synthetic Co., Ltd., a Japanese company. .

상기 은계 무기항균제는 은이온이 세균에 작용하여 생명유지에 필요한 대사기능을 저해하고, 물과 빛의 존재하에서 활성산소(·O2)를 발생시켜 세균의 세포막을 파괴한다.The silver-based inorganic antimicrobial agent inhibits the metabolic function required for the maintenance of life by the action of silver ions and generates free radicals (· O 2 ) in the presence of water and light to destroy bacterial cell membranes.

은계 무기항균제의 평균 입자직경이 1.0㎛를 초과하는 경우에는 2데니어 미만의 가는 원사 제조가 어렵고 방사팩 압력이 크게 상승되어 조업성(Full-Drum율)이 크게 저하되고, 0.1㎛ 미만인 경우에는 항균제의 분산성이 나빠져 작업성이 저하되고 원가가 비싸진다.If the average particle diameter of the silver-based inorganic antimicrobial agent exceeds 1.0 μm, it is difficult to produce fine yarns of less than 2 denier, and the spin pack pressure is greatly increased, resulting in a significant drop in the full-drum rate. The dispersibility of the product is poor, the workability is lowered and the cost is high.

한편, 상기의 은계 무기항균제의 원사내 함량이 2.0중량%를 초과하는 경우에는 제조원가가 비싸지고 분산성이 떨어져 조업성이 나빠지고, 0.3중량% 미만인 경우에는 충분한 항균기능을 얻을 수 없다.On the other hand, if the content of the silver-based inorganic antimicrobial agent in the yarn exceeds 2.0% by weight, the manufacturing cost is expensive, poor dispersibility, poor operation, and less than 0.3% by weight can not obtain sufficient antibacterial function.

본 발명의 공기교락사를 이루는 멀티필라멘트는 도 1과 같은 공정을 거쳐 제조할 수 있다. 도 1은 본 발명의 멀티필라멘트를 제조하는 공정 개략도이다. The multifilament forming the air entangled yarn of the present invention can be produced through the process as shown in FIG. 1 is a process schematic diagram of producing a multifilament of the present invention.                     

구체적으로, 열가소성 폴리머 칩 이송배관(1)을 통해 열가소성 폴리머 칩을 익스트루더(3)에 공급함과 동시에 상기 은계 무기항균제가 첨가된 열가소성 폴리머 칩(이하 "마스터 배치 칩"이라고 한다)을 사이드 피더(2)를 통해 상기의 익스트루더(3)에 함께 공급한다. 계속해서 익스트루더(3)에서 공급된 열가소성 폴리머 칩과 은계 무기항균제가 첨가된 열가소성 폴리머 칩(마스터 배치 칩)을 함께 용융, 혼합한다.Specifically, the thermoplastic polymer chip (hereinafter referred to as a "master batch chip") to which the silver-based inorganic antimicrobial agent is added while supplying the thermoplastic polymer chip to the extruder 3 through the thermoplastic polymer chip conveying pipe 1 is referred to as a side feeder. (2) is supplied to the extruder (3) together. Subsequently, the thermoplastic polymer chip supplied from the extruder 3 and the thermoplastic polymer chip (master batch chip) to which the silver inorganic antibacterial agent is added are melted and mixed together.

계속해서, 용융된 폴리머를 도 4와 같은 단면을 갖는 방사구금(4)을 통해 용융방사한 후, 냉각쳄버(5)로 냉각하고, 집속가이드(6)를 거쳐 제 1 고뎃롤(7)과 제 2 고뎃롤(8) 사이에서 연신한 후 권취기(9)로 권취하여 본 발명의 공기교락사를 이루는 멀티필라멘트를 제조할 수 있다.Subsequently, the molten polymer is melt-spun through the spinneret 4 having the cross section as shown in FIG. 4, and then cooled by the cooling chamber 5, and then through the focusing guide 6, the first gourd roll 7 and the like. After stretching between the second goug rolls (8) can be wound with a winder (9) to produce a multifilament forming the air entangled yarn of the present invention.

제 1 고뎃롤(7)의 온도는 85℃정도, 회전 선속도는 1,500m/분 정도가 바람직하다.It is preferable that the temperature of the 1st gourd roll 7 is about 85 degreeC, and the rotational linear speed is about 1,500 m / min.

제 2 고뎃롤(8)의 온도는 123℃정도, 회전 선속도는 4,300m/분 정도가 바람직하다.It is preferable that the temperature of the 2nd goth roll 8 is about 123 degreeC, and the rotational linear velocity is about 4,300 m / min.

권취기(9)의 권취속도는 4,200m/분 정도가 바람직하다.The winding speed of the winder 9 is preferably about 4,200 m / min.

그러나 본 발명에서는 제 1 고뎃롤(7), 제 2 고뎃롤(8) 및 권취기(9)의 회전 선속도 및 온도를 특별하게 한정하는 것은 아니다.However, in the present invention, the linear linear velocity and temperature of the first gouge roll 7, the second gouge roll 8, and the take-up machine 9 are not particularly limited.

이때, 은계 무기항균제를 익스트루더(3)에 직접 투입하는 것 보다 상기와 같이 마스터 배치 칩을 제조한 후 이를 사이드 피더(2)를 통해 익스트루더(3)로 공급하는 것이 항균제의 분산성과 조업성에 보다 바람직하다. At this time, rather than directly injecting the silver-based inorganic antimicrobial agent to the extruder (3) to produce a master batch chip as described above and to supply it to the extruder (3) through the side feeder (2) dispersibility of the antimicrobial agent It is more preferable for operability.                     

다음으로, 본 발명의 공기교락사는 상기와 같이 제조된 멀티필라멘트들을 도 2와 같이 공기교락하여 제조할 수 있다. 이때 공기교락에 의해 형성되는 교락점이 80개/m이상으로 형성시키고, 권취장력은 사층이 붕괴되지 않는 수준내에서 최소화한다.Next, the air entangled yarn of the present invention can be produced by air entangled as shown in FIG. At this time, the entanglement formed by air entanglement is formed to more than 80 / m, the winding tension is minimized within the level that does not collapse.

교락점이 80개/m미만인 경우에는 사염시 사층이 쉽게 붕괴되는 문제가 발생되며, 권취장력이 높으면 사염시 치즈(Cheese)에 감겨져 있는 원사를 빼어내서 스풀(Spool)에 끼우기 어렵게 된다.If the entanglement point is less than 80 / m, a problem occurs that the four layers easily collapsed when weaving, and if the winding tension is high, it is difficult to pull out the yarn wound on the cheese (Cheese) and to insert it into the spool.

다음으로, 상기와 같이 제조된 공기교락사를 통상의 사염조건하에서 염색하여 염색된 공기교락사를 제조한다.Next, the air entangled yarn prepared as described above is dyed under ordinary dyeing conditions to prepare a dyed air entangled yarn.

사염시에는 치즈(Cheese)에 감겨있는 공기교락사를 빼어내서 사염용 스풀(Spool)에 끼워 넣은 다음 염색을 하고, 다시 스풀에 원사를 빼어내어 치즈(Cheese)에 다시 끼워 놓는 공정을 거치게 된다.In the case of dyeing, the air entangled yarn wrapped in cheese is taken out and inserted into a spool for dyeing, then dyed, and the yarn is removed from the spool and put back into the cheese.

본 발명의 공기교락사는 KS K 0693-2001 방법으로 측정한 정균감소율이 99.00 ~ 99.99%이고, 정균활성치가 2.2 ~ 6.3이다.Air entangled sand of the present invention is 99.00 ~ 99.99% bacteriostatic reduction measured by KS K 0693-2001 method, the bacteriostatic activity is 2.2 ~ 6.3.

본 발명에 있어서, 조업성 및 원사의 각종 물성은 아래와 같이 측정(평가)하였다.
In the present invention, the operability and various physical properties of the yarn were measured (evaluated) as follows.
