Description

항균성과 탈취성이 우수한 폴리에스터 섬유의 제조방법Method for producing polyester fiber with excellent antibacterial and deodorant properties

본 발명은 우리의 일상 생활에서 가장 밀접한 관계가 있는 합성섬유중 특히 폴리에스터 항균성 및 탈취성을 부여하여 미생물의 번식으로 인한 섬유재료의 취화, 착색 오염 및 생활주변의 악취를 탈취하여 항상 쾌적한 느낌을 주는 폴리에스터 위생 섬유의 제조방법에 관한 것이다.The present invention provides polyester antimicrobial and deodorizing properties among the most closely related synthetic fibers in our daily lives, thereby deodorizing embrittlement, coloring contamination and odors around the living environment due to the growth of microorganisms, so as to always feel comfortable. The present invention relates to a method for producing polyester sanitary fibers.

침장류, 인테리어 제품, 의류, 가정용품 및 산업자재용품들에 광범위하게 이용되고 있는 폴리에스터 섬유는 우리의 일상 생활중에서 각종 세균류, 곰팡이류등에 노출되어 있어, 직접, 간접으로 피해를 받고 있다.Polyester fiber, which is widely used in bedding, interior products, clothing, housewares and industrial materials, is exposed to various germs, molds, etc. in our daily lives, and is directly and indirectly damaged.

이들 미생물 가운데는 인체에 직접 해는 주지 않지만, 섬유재료의 변질, 취화 및 착색오염을 일으키거나 악취를 발생시키는 것도 있고, 병원성으로 해를 주는 것도 있다.Some of these microorganisms do not directly harm the human body, but may cause deterioration, embrittlement and staining of textile materials, odors, and other pathogenic diseases.

종래에는 폴리에스터 섬유에 항균성을 부여하는 방법으로서 폴리 에스터 섬유 제조후 후가공법으로 항균성 화합물을 부여하는 방법과 폴리에스터 섬유 중합 또는 방사시 항균성 화합물을 부여하는 방법등이 실시되었고, 또한 섬유에 탈취성을 부여하는 방법으로는 폴리에스터 섬유에 향기나는 물질을 부여하여 악취를 중화시키는 방법과 악취를 화학반응 또는 흡착등을 통해 제거할 수 있는 물질을 폴리에스터 섬유에 부여하는 방법등이 실시되었다.Conventionally, as a method of imparting antimicrobial properties to polyester fibers, a method of imparting an antimicrobial compound by post-processing after the production of polyester fiber and a method of imparting an antimicrobial compound during polyester fiber polymerization or spinning is performed. As a method of imparting a method to impart a fragrant substance to the polyester fiber to neutralize the odor, and a method of imparting to the polyester fiber a substance capable of removing the odor through a chemical reaction or adsorption.

그러나, 이들 방법은 항균성 및 탈취성을 부여하기에 미흡한 점이 있으며 항균성 및 탈취성을 동시에 부여하는 방법은 널리 알려진 바가 없다.However, these methods are inadequate to impart antimicrobial and deodorant properties, and methods for simultaneously providing antimicrobial and deodorant properties are not well known.

본 발명은 항균성 및 탈취성을 동시에 부여하고, 또한 세탁 내구성을 증대시키기 위한 것으로서 제오라이트(zeolite)의 우수한 이온교환성 및 흡착성에 착안하여 제오라이트를 중합시 첨가하므로써 항균성 및 탈취성이 우수한 폴리에스터 섬유를 제조하는 것을 그 목적으로 한다.The present invention provides both antimicrobial and deodorizing properties at the same time, and also increases washing durability, and focuses on the excellent ion exchange and adsorption properties of zeolites to add zeolites during polymerization to produce polyester fibers having excellent antibacterial and deodorizing properties. It aims to manufacture it.

본 발명에서는 디올과 디카르본산 또는 그 에스테르 반응으로 생성되는 폴리에스터 섬유제조시, 제오라이트의 한종류안 모더나이트(Mordenite)를 강산으로 비등처리 및 스팀(steam)처리로, 실리카/알루미나비(SiO2/Al2O3mole ratio)를 33 내지 100으로 조절한 것(A)과, 마찬가지 방법으로 실리카/알루미나비를 10 내지 33으로 조절한 후 은, 구리, 아연 등의 살균성 금속을 이온교환시킨 것(B)을, 평균 입자크기가 0.5㎛ 내지 2.5㎛가 되도록 조절하여 (A)와 (B)를 2:1의 비로 혼합한 조성물을 0.5 내지 3.0중량부 함유하도록 하는 것을 특징으로 한다.In the present invention, when preparing a polyester fiber produced by the reaction of diol and dicarboxylic acid or esters thereof, mordenite of zeolite by boiling and steam treatment with strong acid, silica / alumina ratio (SiO 2) / Al 2 O 3 mole ratio) is adjusted to 33 to 100 (A) and the silica / alumina ratio to 10 to 33 by the same method and then ion-exchanged silver, copper, zinc, etc. It is characterized by containing (B) 0.5-3.0 weight part of compositions which mixed (A) and (B) in the ratio of 2: 1 so that average particle size might be set to 0.5 micrometer-2.5 micrometers.

(단, M은 원자가 n의 금속, x+y는 단위 격자당 사면체의 수, z는 물 분자의 mole수)로 표시되는 제오라이트는 비표면적이 대단히 큰 다공성으로 수분등의 극성물질에 대한 친화력이 대단히 커, 흡착제로 널리 이용되는 물질로서 실리카-알루미나(silica-alumina)가 주성분 원소이고 TO4(T=Si, Al)사면체가 서로 산소원자를 공유하면서 3차원으로 구성되어 있는 결합체이다.Zeolite represented by (M is a metal of valence n, x + y is the number of tetrahedrons per unit lattice, z is the number of moles of water molecules) has a very large specific surface area and affinity for polar substances such as moisture. As a very large material widely used as an adsorbent, silica-alumina is a main component and a TO 4 (T = Si, Al) tetrahedron is a combination consisting of three dimensions while sharing oxygen atoms with each other.

구조내에서 산소원자는 두 개의 사면체를 공유하기 때문에 격자는 음(-)의 전기를 띠게 되며 따라서 구조내 교환성능이 있는 양이온과 균형을 이루게 된다. 이런 특징으로 인하여 수분이 많은 곳에서는 수분이 우선 흡수되고, 포화된 후에는 흡착기능을 더 이상 발휘하지 못하기 때문에 악취가스를 제거하지 못하게 된다.Because oxygen atoms share two tetrahedrons within the structure, the lattice is negatively charged, thus balancing the cations with exchange performance in the structure. Due to this feature, water is absorbed first in a place where there is a lot of water, and after saturation, the adsorption function is no longer exerted, thus preventing the removal of odor gas.

본 발명에서는 제오라이트를 강산으로 비등처리 및 스팀처리하여 제오라이트의 수분에 대한 친화력을 감소시키고, 제오라이트내 미세공을 확대시켜 악취가스의 흡착을 용이하게함으로써 탈취효과를 극대화시키는 특징을 갖는다.In the present invention, the zeolite is boiled and steamed with a strong acid to reduce the affinity of the zeolite for moisture, and to enlarge the micropores in the zeolite to facilitate the adsorption of odor gas, thereby maximizing the deodorizing effect.

또한 이온교환된 은, 구리, 아연 등의 살균성 금속이 제오라이트 모체중에 안정한 상태로 결합되어 금속이온의 용출이 거의 무시되므로 초기 항균성 뿐만 아니라, 항균성의 지속성도 대단히 우수한 특징이 있다.In addition, disinfectant metals such as silver, copper, and zinc, which are ion exchanged, are bonded in the zeolite matrix in a stable state, and thus eluting of metal ions is almost ignored.

일반적으로 살균을 목적으로 Na형 제오라이트에 이온교환시 은이온은 0.01 내지 5중량%(무수기준), 구리이온은 0.03 내지 10중량%(무수 기준), 아연이온은 0.04 내지 14중량%(무수기준)가 좋다고 알려져 있고, 탈취를 목적으로 하는 경우는 화학처리로 제어라이트의 상온에서 물에 대한 흡착능력을 10% 미만으로 하면, 원하는 만큼의 탈취효과를 낼 수 있는 것으로 알려져 있다.Generally, silver ion is 0.01 to 5% by weight (anhydrous basis), copper ion is 0.03 to 10% by weight (anhydrous basis), and zinc ion is 0.04 to 14% by weight (anhydrous basis). In the case of deodorization, it is known that if the adsorption capacity to water is less than 10% at room temperature of the control light by chemical treatment, the deodorizing effect can be achieved as much as desired.

본 발명에서는 모더나이트를 강산으로 비등처리하여 실리카/알루미나비를 33 내지 100으로 조절한 것과 동일한 방법으로 실리카/알루미나 비를 10 내지 33으로 조절한 후 살균성 금속인 은, 구리, 아연 등을 이온 교환시킨 것을 혼합하여 입자크기를 0.5㎛ 내지 3.0㎛로 조절한 후 에틸렌글리콜에 분산시켜, 통상의 폴리에스테르 합성공정중 충축합반응 완결이전 임의의 단계에서 투입하는 것을 특징으로 한다.In the present invention, by controlling the silica / alumina ratio to 10 to 33 by the same method that the mordenite is boiled with a strong acid to adjust the silica / alumina ratio to 33 to 100 after ionization of silver, copper, zinc, etc. After mixing the mixture to adjust the particle size from 0.5㎛ to 3.0㎛ characterized in that it is dispersed in ethylene glycol, it is characterized in that the input at any stage before the completion of the condensation reaction in the conventional polyester synthesis process.

실리카/알루미나비가 항균성을 목적으로 할 경우에 10이하이면 항균성이 나빠지고 33이상인 경우에는 항균성의 향상에 도움을 주지 못하고 제조시 많은 노력이 필요하기 때문에 경제적으로 바람직하지 못하다. 또한 탈취를 목적으로 할 경우에 실리카/알루미나비가 33이하이면 악취가스에 대한 흡착능이 떨어져 악취제거능력이 나쁘고, 100이상의 경우에는 악취가스 흡착능의 향상이 크지 않으므로 경제적인 측면에서 바람직하지 못하다.If the silica / alumina ratio for the antimicrobial purpose is less than 10 antimicrobial deterioration, if the 33 or more is not economically preferable because it does not help to improve the antimicrobial and requires a lot of effort in manufacturing. In the case of deodorization, if the silica / alumina ratio is 33 or less, the adsorption capacity for the odor gas is poor, and the odor removal ability is poor, and in the case of 100 or more, the improvement of the odor gas adsorption capacity is not so large.

이하 실시예에 의거 본 발명을 구체적으로 설명한다.The present invention will be described in detail with reference to the following Examples.
