Description
본 발명은 셀룰로오스 아세테이트로부터 연속적 알칼리 처리에 의하여 셀룰로오스 섬유를 제조하는 방법에 관한 것이다.The present invention relates to a process for producing cellulose fibers by continuous alkali treatment from cellulose acetate.
종래, 셀룰로오스 아세테이트로부터 셀룰로오스 섬유를 제조하기 위한 알칼리 처리 방법으로는 액류 염색기에 일정량의 원단을 투입하여 처리하는 배치(Batch)방식이 있다.Conventionally, an alkali treatment method for producing cellulose fibers from cellulose acetate has a batch method in which a certain amount of fabric is added and treated in a liquid dyeing machine.
그러나, 위와 같은 불연속적인 배치방식은 셀룰로오스 아세테이트를 셀룰로오스 섬유로 전환시키는 반응시간이 길고 배치(Batch)당 투입량이 한정되어 있어 제조 원가가 상승하는 문제점이 발생한다.However, the discontinuous batch method as described above has a long reaction time for converting cellulose acetate into cellulose fibers and a limited input amount per batch, resulting in an increase in manufacturing cost.
또한 종래의 알칼리 처리 방법으로는 연속감량기를 사용하는 연속적 알칼리 처리 방법이 있다. 이 방법은 폴리에스테르 직물 감량에 주로 사용하는데, 높은 온도와 고농도의 알칼리 조건을 요한다. 폴리에스테르 직물의 감량에 사용되는 연속감량기를 사용하여 셀룰로오스 아세테이트로부터 셀룰로오스 섬유를 제조하는 경우에는 균일한 반응을 일으키지 못해 우수한 품질의 셀룰로오스 섬유를 제조하는 데에는 부적합하다.In addition, a conventional alkali treatment method includes a continuous alkali treatment method using a continuous reducer. This method is mainly used for weight loss of polyester fabrics, requiring high temperature and high alkalinity conditions. The production of cellulose fibers from cellulose acetate using a continuous reducer used to reduce polyester fabrics is not suitable for producing good quality cellulose fibers because they do not cause uniform reactions.
따라서, 본 발명은 상기한 바와 같은 선행기술의 문제점이 없이 저온 조건에서 연속적 알칼리 처리 방법에 의해 셀룰로오스 아세테이트로부터 셀룰로오스 섬유를 제조하는 새로운 방법을 제공하는 것을 목적으로 한다.It is therefore an object of the present invention to provide a new method for producing cellulose fibers from cellulose acetate by a continuous alkali treatment method at low temperature conditions without the problems of the prior art as described above.
상기한 목적을 달성한 본 발명에 의하면 치환도 2.0~2.75(초산화도 45~59.5%)의 셀룰로오스 디아세테이트를 적어도 일부 함유하는 섬유 또는 섬유제품을 저온에서 연속적 알칼리 처리 방법에 의해 셀룰로오스 아세테이트 섬유를 셀룰로오스 섬유로 전환시키는 공정을 포함하는 것을 특징으로 하는 셀룰로오스 섬유의 제조 방법이 제공된다.According to the present invention which achieves the above object, a cellulose acetate fiber is prepared by continuous alkali treatment at a low temperature for a fiber or a textile product containing at least a portion of cellulose diacetate having a degree of substitution of 2.0 to 2.75 (superoxidation degree of 45 to 59.5%). There is provided a process for producing cellulose fibers, comprising the step of converting them to cellulose fibers.
이하, 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
셀룰로오스 디아세테이트를 알칼리 처리하면 아세틸기가 히드록시기로 전환되는 검화가 일어나게 되는데 이때 무정형으로 존재하던 디아세테이트 섬유의 분자쇄들의 폴딩(folding)과 패킹(packing) 등의 재배열로 결정화가 일어난다. 일반적으로 천연의 셀룰로오스는 셀룰로오스Ⅰ의 결정구조를 가지게 되며 재생 셀룰로오스 섬유의 경우는 셀룰로오스Ⅱ의 구조를 가지는 데 반해 셀룰로오스 디아세테이트의 검화에 의해 제조된 셀룰로오스 섬유는 셀룰로오스Ⅱ와 Ⅵ가 혼합된 결정구조를 가지게 되며, 결정화도(비중법) 14~34%, 복굴절율 0.012~0.024이다.Alkali treatment of cellulose diacetate results in saponification in which acetyl groups are converted to hydroxy groups. Crystallization occurs due to rearrangement of folding and packing of molecular chains of diacetate fibers that were amorphous. In general, natural cellulose has a crystalline structure of cellulose I. In the case of regenerated cellulose fibers, cellulose II has a structure of cellulose, whereas cellulose fibers prepared by saponification of cellulose diacetate have a crystal structure of cellulose II and VI. Crystallinity (specific gravity method) 14-34%, birefringence 0.012 ~ 0.024.
셀룰로오스 디아세테이트 섬유의 검화에 의해 얻어지는 셀룰로오스 섬유도 일종의 레이온 섬유이다. 이러한 셀룰로오스 섬유의 물성은 비중이 1.48~1.51gm/cm3, 인장강도 1.2~2.5gf/de, 신도 20~50%, 표준상태 수분율 12~16%로 일반 레이온과 유사한 성능을 보인다.The cellulose fiber obtained by saponification of a cellulose diacetate fiber is also a kind of rayon fiber. The specific properties of these cellulose fibers are 1.48 ~ 1.51gm / cm 3 , tensile strength 1.2 ~ 2.5gf / de, elongation 20 ~ 50%, standard moisture content 12 ~ 16%.
본 발명에서 검화 혹은 알칼리 처리에는 강알칼리 단독 처리 또는 강알칼리와 약알칼리의 동욕처리 또는 이욕처리 방법을 이용할 수 있다.In the present invention, for saponification or alkali treatment, strong alkali alone treatment or copper bath treatment or strong bath treatment method of strong alkali and weak alkali can be used.
검화 과정에서 사용될 수 있는 알칼리화합물의 예로는 수산화나트륨 등과 같은 알칼리금속수산화물, 수산화칼슘 등과 같은 알칼리토금속류수산화물, 탄산나트륨 등과 같은 알칼리 금속탄산염 등이 있다. 이러한 알칼리 화합물은 단독으로 사용할 수도 있고, 또는 반응 속도 조절제를 병용하여 사용할 수도 있다. 반응속도조절제로는 포스포늄계 반응 속도 조절제와 4급암모늄계 반응 속도 조절제가 잘 알려져 있다. 반응 속도 조절제의 시중 구입 가능한 예로는 포스포늄계인 네오레이트 엔씨비(NEORATE NCB : 한국정밀제품) ; 제4급암모늄계인 케이에프 네오레이트 엔에이-40(KF NEORATE NA-40 : 한국정밀제품), 디와이케이-1125[DYK-1125 : 일본의 일방사(一方社)제품], 카세린PES, 카세린 PEL, 카세린 PEF[이상 일본의 명성화학(明成化學)제품], 스노겐 피디에스(SNOGEN PDS : 한국의 대영 화학제품)등을 들 수 있다.Examples of alkali compounds that can be used in the saponification process include alkali metal hydroxides such as sodium hydroxide, alkaline earth metal hydroxides such as calcium hydroxide, alkali metal carbonates such as sodium carbonate, and the like. These alkali compounds may be used alone or in combination with a reaction rate regulator. As the reaction rate regulator, phosphonium-based reaction rate regulators and quaternary ammonium-based reaction rate regulators are well known. Commercially available examples of reaction rate regulators include phosphonium-based neorate NCB (NEORATE NCB); KF NEORATE NA-40 (KF NEORATE NA-40: Korea Precision Products), DYK-1125 [Japan's one-sided yarn], Casein PES, Car And serine PEL, casein PEF (above Japan's famous chemical products), and SNOGEN PDS (Korean British Chemicals).
본 발명에서는 셀룰로오스 섬유를 제조하기 위한 원료로서 치환도 2.0~2.75의 셀룰로오스 디아세테이트를 적어도 일부 함유하는 섬유 또는 섬유제품을 사용한다.In the present invention, a fiber or a textile product containing at least a part of cellulose diacetate having a degree of substitution of 2.0 to 2.75 is used as a raw material for producing cellulose fibers.
또한, 본 발명에서는 상기와 같은 섬유로부터 셀룰로오스 섬유를 전환하는데 있어서, 저온에서 연속적 처리 방법에 의해 알칼리 처리하는 공정을 포함하는 것을 특징으로 하는데, 반응조건과 공정과정의 일예는 다음과 같다.In addition, the present invention is characterized in that in the conversion of cellulose fibers from the fibers as described above, comprising a step of alkali treatment by a continuous treatment method at a low temperature, an example of the reaction conditions and process is as follows.
콜드 패드 배치(Cold-Pad-Batch) 감량기의 패딩(Padding)조에 20~53%의 알칼리 수용액을 준비하고, 준비된 알칼리 수용액에 정련 건조한 셀룰로오스 디아세테이트 섬유를 일부 함유하는 섬유 또는 섬유제품을 침지하여 50~100% 웨트 픽업(Wet Pick-up)시킨다. 웨트 픽업시킨 섬유를 저장 롤(Roll)에 권취하고, 권취한 섬유를 20oC 이상 70oC 이하에서 1~48시간 동안 처리한 후 수세하여 셀룰로오스 섬유를 제조한다.Prepare 20-53% aqueous alkali solution in the padding tank of cold-pad batch reducer, and immerse the fibrous or fibrous product containing some refined dried cellulose diacetate fibers in the prepared aqueous alkali solution. ~ 100% Wet Pick-up. The wet-picked fibers are wound on a storage roll, and the wound fibers are treated at 20 ° C. or higher and 70 ° C. or lower for 1 to 48 hours and washed with water to prepare cellulose fibers.
상기 알칼리 수용액의 농도는 20~53% 범위내로 하는 것이 바람직하다. 이는 20% 미만에서는 반응이 불충분하며, 53% 초과시에는 알칼리 수용액이 수산화나트륨(NaOH)의 포화상태가 되어 용액을 제조하는 것이 불가능하기 때문이다.It is preferable to make the density | concentration of the said alkali aqueous solution into 20 to 53% of range. This is because the reaction is insufficient at less than 20%, and when it is above 53%, the aqueous alkali solution becomes saturated with sodium hydroxide (NaOH), making it impossible to prepare a solution.
또한, 본 발명의 공정중 알칼리 처리하는데 있어서 알칼리 처리 온도는 20oC 이상 70oC 이하가 바람직한데, 20oC 미만에서는 반응이 불충분하며, 70oC을 초과하는경우에는 불균일 반응과 분자쇄 절단이 일어나게 되어 본 발명에 부적합하게 된다.Further, according to an alkali treatment in the process of the present invention the alkaline processing temperature together is 20 o or more C 70 o C or less preferably, 20 o C less than the and the reaction is insufficient, 70 o, if it exceeds the C is non-uniform reaction, and the molecular chain Cleavage will occur which makes it unsuitable for the present invention.

Water was added at room temperature and washed with water to remove residual alkali and dried the fibers. Through this saponification process, a fiber having a loss ratio of 40% relative to the initial diacetate fiber weight was obtained.

It has similar characteristics to the cellulose fibers produced by it, so it can be applied to the same use, and also by the continuous processing method at low temperature, it has the advantage of being manufactured in a simple manufacturing process, low manufacturing cost, and safe operating conditions. .
