셀룰로오스계 성형체의 처리 방법 {METHOD FOR TREATING CELLULOSIC MOULDED BODIES}Processing method of cellulose molded body {METHOD FOR TREATING CELLULOSIC MOULDED BODIES}

본 발명은 수성 3급 아민 옥사이드 중의 셀룰로오스 용액으로부터 제조되는 셀룰로오스계 성형체, 특히 섬유 및 이들 섬유를 함유하는 조립체(assembly)의 처리 방법에 관한 것으로, 이 방법에서 성형체에 향상된 특성을 부여하기 위해 상기 성형체를 직물 조제(textile auxiliary agent)에 접촉시킨다.FIELD OF THE INVENTION The present invention relates to a process for the treatment of cellulosic shaped bodies, in particular fibers and assemblies containing these fibers, prepared from cellulose solutions in aqueous tertiary amine oxides, in which the shaped bodies are provided for imparting improved properties to the shaped bodies. Is contacted with a textile auxiliary agent.

본 발명에 있어서 "성형체"라는 용어의 의미는 특히 스펀지도 포함한다.The meaning of the term "molded body" in the present invention includes in particular a sponge.

비스코스 프로세스의 대안으로서 최근에는 유도체를 형성하지 않으면서 셀룰로오스를 유기 용매, 유기 용매와 무기염의 혼합물, 또는 소금물에 용해시키는 여러 가지 방법이 제시되었다. 그러한 용액으로부터 제조된 셀룰로오스 섬유를 "용매 방사형 섬유(solvent-spun fibre)"라 칭하며 BISFA(The International Bureau for the Standardisation of man made Fibres; 인공 섬유의 표준화를 위한 국제 기구)에 의해 라이오셀(Lyocell)이라는 일반명이 부여되었다. 라이오셀이라는 명칭으로서 BISFA는 유기 용매로부터 방사 공정에 의해 얻어지는 셀룰로오스 섬유를 정의한다. "유기 용매"에 대해 BISFA는 유기 화합물과 물의 혼합물로 이해하며, "용매 방사(solvent-spinning)"란 유도체 형성 없는 용해 및 방사를 의미하는 것으로 간주한다.As an alternative to the viscose process, several methods have recently been proposed for dissolving cellulose in organic solvents, mixtures of organic and inorganic salts, or brine without forming derivatives. Cellulose fibers made from such solutions are called "solvent-spun fibers" and are lyocelled by the International Bureau for the Standardization of man made Fibers (BISFA). The generic name was given. BISFA, by the name of lyocells, defines cellulose fibers obtained by spinning processes from organic solvents. For "organic solvent" BISFA is understood to be a mixture of organic compounds and water, and "solvent-spinning" is considered to mean dissolution and spinning without derivative formation.

그러나, 현재까지 용매 방사 셀룰로오스 섬유의 제조 방법으로는 단 한 가지 방법이 산업 규모로 실현되었을 뿐이다. 이 방법에서는, 3급 아민 옥사이드, 특히 N-메틸모르폴린-N-옥사이드(NMMO)가 용매로 사용된다. 상기 방법은, 예를 들면. 특허문헌 US-A 4,246,221에 개시되어 있으며, 높은 점착성(tenacity), 높은 습윤계수(wet-modulus) 및 높은 루프 강도(loop strength)를 특징으로 하는 섬유를 제공한다.However, to date, only one method has been realized on an industrial scale for producing solvent-spun cellulose fibers. In this process, tertiary amine oxides, in particular N-methylmorpholine-N-oxide (NMMO), are used as the solvent. The method is for example. Patent Document US-A 4,246,221 discloses a fiber characterized by high tenacity, high wet-modulus and high loop strength.

특허문헌 WO 99/19555에는 용매 방사 섬유의 처리 방법으로서, 상기 섬유를 2,4-디클로로-6-하이드록시-1.3.5-트리아진 또는 그의 염에 각각 접촉시키는 방법이 개시되어 있다. 상기 방법으로 제조된 섬유는 피브릴화(fibrillation)에 대한 양호한 내성을 갖는 것을 특징으로 한다.Patent document WO 99/19555 discloses a method of contacting 2,4-dichloro-6-hydroxy-1.3.5-triazine or a salt thereof as a method of treating solvent-spun fibers. The fibers produced by this method are characterized by having good resistance to fibrillation.

특허문헌 US 5,728,823을 통해 사이클로덱스트린 유도체, 그 중에서도 2-클로로-4-하이드록시-1.3.5-트라아지닐-사이클로덱스트린의 나트륨염이 공지되어 있다. 특허문헌 US 5,728,823에는 또한 사이클로덱스트린 유도체가 결합되어 있는 멤브레인, 필름, 직물 또는 피혁이 기재되어 있다. 사이클로덱스트린 유도체로 처리된 직물은, 예를 들면, 불쾌한 냄새를 흡수하는 데에 적합하다.Patent document US Pat. No. 5,728,823 discloses cyclodextrin derivatives, especially the sodium salt of 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin. Patent document US 5,728,823 also describes membranes, films, fabrics or leathers to which cyclodextrin derivatives are bound. Fabrics treated with cyclodextrin derivatives are suitable, for example, for absorbing unpleasant odors.

특허문헌 WO 01/48025에는 가교제에 의해 다당류에 공유 결합을 이룬 사이클로덱스트린이 개시되어 있다.Patent document WO 01/48025 discloses a cyclodextrin covalently bonded to a polysaccharide by a crosslinking agent.

본 발명에 따라, 수성 3급 아민 옥사이드 중의 셀룰로오스 용액으로부터 제 조되는 셀룰로오스계 성형체는 사이클로덱스트린 및/또는 사이클로덱스트린 유도체를 포함하는 직물 조제로 처리됨으로써 개선된 특성을 가진 제품을 형성하는 것으로 밝혀졌다.In accordance with the present invention, cellulosic shaped bodies prepared from cellulose solutions in aqueous tertiary amine oxides have been found to form articles with improved properties by treatment with fabric preparations comprising cyclodextrins and / or cyclodextrin derivatives.

상기 성형체는 건조 불가 상태(never-dried state)의 섬유인 것이 바람직하다. 상기 섬유는 연속 작업형 생산 설비의 후처리 단계에서 건조 불가 상태로 처리될 수 있다.Preferably, the molded body is a fiber in a never-dried state. The fibers can be treated in an undryable state in the post-treatment step of the continuous production production plant.

사이클로덱스트린은 이어서, 예를 들면, 장시간에 걸쳐 방출될 수 있는 처리제를 포함할 수 있는 것으로 알려져 있다. 본 발명에 따른 방법에서, 그러한 처리제를 동시에 및/또는 계속해서 사용하는 연속적 생산 공정중에 사이클로덱스트린 또는 사이클로덱스트린 유도체로 처리된 섬유를 투입할 수 있다.It is known that cyclodextrins may then comprise a treating agent that can be released, for example, over a long period of time. In the process according to the invention, fibers treated with cyclodextrins or cyclodextrin derivatives can be introduced during a continuous production process using such treatments simultaneously and / or continuously.

상기 직물 조제를 사용한 처리는 알칼리성 환경에서 이루어지는 것이 바람직하다.The treatment using the fabric preparation is preferably performed in an alkaline environment.

또한, 상기 직물 조제는 가교제를 추가로 포함하는 것이 바람직하다. 상기 가교제로서 2,4-디클로로-6-하이드록시-1.3.5-트리아진 또는 그의 염을 각각 사용하는 것이 특히 바람직하다.In addition, it is preferable that the fabric preparation further comprises a crosslinking agent. It is particularly preferable to use 2,4-dichloro-6-hydroxy-1.3.5-triazine or a salt thereof as the crosslinking agent, respectively.

특허문헌 US 5,728,823에 따른 최신 기술에서, 예를 들면 2-클로로-4-하이드록시-1.3.5-트리아지닐-사이클로덱스트린과 같은 사이클로덱스트린 유도체는 먼저, 후속 처리하고자 하는 물질에 상기 유도체를 적용하기 위해 많은 노력을 들여 제조되어야 한다.In the state of the art according to patent document US Pat. No. 5,728,823, cyclodextrin derivatives such as, for example, 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin are first applied to the substance to be subsequently treated. It must be manufactured with great effort.

사이클로덱스트린 및 가교제, 특히 2,4-디클로로-6-하이드록시-1.3.5-트리아 진은 먼저 이들 두 물질로 된 화합물을 제조할 필요 없이 처리하고자 하는 섬유에 첨가됨으로써 양호한 결과를 얻을 수 있음이 밝혀졌다.Cyclodextrins and crosslinkers, in particular 2,4-dichloro-6-hydroxy-1.3.5-triazine, can be obtained with good results by being added to the fibers to be treated without first having to prepare compounds of these two materials. Turned out.

본 발명의 또 다른 실시예에서, 상기 직물 조제는 2-클로로-4-하이드록시-1.3.5-트리아지닐-사이클로덱스트린(MCT-CD) 또는 그의 염을 각각 포함한다.In another embodiment of the invention, the fabric preparation comprises 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin (MCT-CD) or salts thereof, respectively.
