복합섬유를 포함하는 직편물의 감량방법 {A method of alkali treatment for woven or knitted fabric with composite fiber}Reduction of woven fabrics containing composite fibers {A method of alkali treatment for woven or knitted fabric with composite fiber}

본 발명은 2성분이 복합되어 있는 복합섬유(Composite fiber)를 포함하는 직편물(이하 "복합섬유 직편물"이라 한다)의 감량방법에 관한 것이다.The present invention relates to a method for reducing a woven fabric (hereinafter referred to as a "composite fiber woven fabric") including a composite fiber in which two components are combined.

보다 구체적으로, 복합섬유를 경사 및/또는 위사로 사용하여 제조된 직물이나 복합섬유로 제조된 편물을 알칼리 수용액으로 처리하여 복합섬유 내 용출성분을 보다 효과적으로 용출하므로서 섬유형성성 성분들이 양호하게 분할될 수 있도록 감량처리하는 방법에 관한 것이다.More specifically, the fiber-forming components can be satisfactorily divided by treating the fabric or the knitted fabric made of the composite fiber using the composite fiber as a warp and / or weft with an aqueous alkali solution to more effectively elute the elution component in the composite fiber. It relates to a method of weight loss treatment so that.

합성섬유 직편물에 천연피혁과 같은 촉감과 외관을 부여하기 위하여 섬유형성성 성분과 용출성분으로 구성되는 복합섬유(composite)를 경사 및/또는 위사로 직물을 제조하거나, 상기 복합섬유를 제편용 원사 전부 또는 일부로 사용하여 편물을 제조한 다음, 이들을 알칼리 수용액으로 감량처리하여 상기 복합섬유 내 용출성분을 용출하므로서 섬유형성성 성분을 분할하고, 계속해서 버핑 및 염색하여 직편물을 제조하는 방법이 널리 사용되어 왔다.In order to give a synthetic fiber woven fabric with the same feel and appearance as natural leather, a composite fabric composed of a fiber-forming component and an eluting component is manufactured with a warp and / or weft, or the composite fiber is a yarn for knitting The fabric is manufactured by using all or part of the fabric, and then the weight loss treatment is carried out with an aqueous alkali solution to elute the eluted component in the composite fiber, thereby dividing the fiber-forming component, followed by buffing and dyeing to produce a knitted fabric. Has been.

복합섬유는 용출후 단사섬도가 0.1데니어 이하인 폴리에스테르 또는 폴리아 미드의 섬유형성성 성분과 알칼리 이용해성인 용출성분을 복합방사하여 이들 이성분이 해도형 또는 분할형 등으로 복합시켜 제조된다.The composite fiber is produced by complex spinning of the fiber-forming component of polyester or polyamide having a single yarn fineness of 0.1 denier or less and the eluting component which is alkali-soluble after dissolution, and these two components are mixed in a sea island type or a split type.

상기 알칼리 이용해성 용출성분은 폴리에틸렌테레프탈레이트에 디메틸-5-설포이소프탈레이트 소디움 솔트(이하 "DMIS"라고 한다) 및/또는 저분자량의 폴리알킬렌글리콜(이하 "PAG"라고 한다)이 공중합 또는 블랜딩된 폴리머 등이 사용된다.The alkali-soluble elution component is copolymerized with polyethylene terephthalate or dimethyl-5-sulfoisophthalate sodium salt (hereinafter referred to as "DMIS") and / or low molecular weight polyalkylene glycol (hereinafter referred to as "PAG"). Blended polymers and the like are used.

그러나, 상기의 종래방법은 복합섬유를 포함하는 직편물을 알칼리 수용액만으로 처리하기 때문에 온도 및 처리시간 등의 감량조건이 다소 변경될 경우 용출성분이 완전하게 용출되지 않고, 이로 인해 섬유형성성 성분이 완전하게 분할 또는 분리되지 않은 상태, 다시말해 섬유다발 형태 그대로 존재하는 상태가 되어 염색시 직편물에 색차를 일으키는 줄(Line) 발생이 심하게 되는 문제가 있었다.However, in the conventional method, since the knitted fabric containing the composite fiber is treated only with an aqueous alkali solution, the eluting component is not completely eluted when the weight loss conditions such as temperature and processing time are changed slightly, and thus the fiber forming component is There was a problem that the line is not completely divided or separated, that is, the state of the fiber bundle is present as it is in the form of color, causing a color difference in the knitted fabric.

이로 인해, 감량공정 관리가 어려워지고 과도한 감량처리시에는 원사물성이 손상되는 문제도 발생 되었다.As a result, it is difficult to control the weight loss process and the problem of damage to the yarn properties during excessive weight loss process.

본 발명의 목적은 이와 같은 종래 문제점들을 해결하기 위해 복합섬유를 포함하는 직편물을 감량처리할 때 감량조건이 다소 변동되어도 섬유형성성 성분들을 완전하게 분리시킬 수 있는 감량방법을 제공하기 위한 것이다.An object of the present invention is to provide a weight loss method that can completely separate the fiber-forming components even if the weight loss conditions slightly vary when processing the woven fabric containing a composite fiber in order to solve such a conventional problem.

본 발명은 감량조건이 다소 변경되어도 복합섬유 내 섬유형성성 성분의 분할성을 향상시킬 수 있어서 염색시 줄 발생 문제를 해결할 수 있고, 감량공정 관리도 용이한 복합섬유 직편물의 감량방법을 제공하고자 한다.The present invention can improve the splitability of the fiber-forming component in the composite fiber even if the weight loss conditions are somewhat changed to solve the problem of the generation of the dye line, to provide a method for reducing the composite fiber knitted fabric easy to manage the weight loss process do.

이와 같은 과제를 달성하기 위해 본 발명은 폴리에틸렌테레프탈레이트가 90몰% 이상인 폴리에스테르의 섬유형성성 성분과 알칼리 이용해성인 공중합 폴리에스테르의 용출성분으로 구성되는 복합섬유를 포함하는 직편물을 알칼리 수용액으로 감량할 때, 수용성기로 설폰산염 또는 황산에스테르염을 갖는 탄소수 5~10의 저급 알킬기를 함유하는 음이온성 화합물(침투제)을 투입하는 것을 특징으로 한다.In order to achieve the above object, the present invention is to reduce the knitted fabric comprising a composite fiber composed of a fiber-forming component of the polyester of polyethylene terephthalate of 90 mol% or more and the elution component of the alkali-soluble co-polyester with an aqueous alkali solution When an anionic compound (penetrant) containing a lower alkyl group having 5 to 10 carbon atoms having a sulfonate or a sulfate ester salt is added.

이하, 본 발명을 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

먼저, 본 발명에 있어서 복합섬유를 포함하는 직편물(복합섬유 직편물)은 복합섬유를 경사 및/또는 위사로 사용하여 제직한 직물과, 제편용 원사의 전부 또는 일부로 복합섬유를 사용하여 제편된 편물 모두를 포함한다.First, in the present invention, a knitted fabric containing a composite fiber (composite fiber knitted fabric) is knitted using a composite fiber as a warp and / or weft yarn and a composite fiber using all or a part of the knitting yarn. Includes all of the knitwear.

또한 직편물을 구성하는 복합섬유는 폴리에틸렌테레프탈레이트가 90몰% 이상인 폴리에스테르의 섬유형성성 성분과 알칼리 이용해성인 공중합 폴리에스테르의 용출성분이 해도형 또는 분할형 등의 형태로 복합방사된 섬유 이다.In addition, the composite fiber constituting the woven fabric is a fiber in which the fiber-forming component of the polyester having a polyethylene terephthalate of 90 mol% or more and the elution component of the alkali-soluble copolyester are composite-spun in the form of a sea island type or a split type.

용출성분으로는 폴리에틸렌테레프탈레이트에 DMIS 및/또는 PAG가 공중합 또는 블랜딩된 폴리머를 사용하는 것이 바람직 하다.As the elution component, it is preferable to use a polymer copolymerized or blended with DMIS and / or PAG in polyethylene terephthalate.

본 발명은 상기 복합섬유 직편물을 알칼리 수용액으로 감량처리 할 때, 수용성기로 설폰산염 또는 황산에스테르염을 갖는 탄소수 5~10의 저급 알킬기를 함유하는 음이온성 화합물을 침투제로 첨가(투입) 한다.In the present invention, when the composite fiber knitted fabric is reduced in aqueous alkali solution, an anionic compound containing a C5-10 lower alkyl group having sulfonate or sulfate ester salt as a water-soluble group is added (injected) as a penetrant.

상기 음이온성 화합물(침투제)로는 소디움-2-에틸-2-옥텐설페이트 등을 사용한다. 음이온성 화합물(침투제)의 첨가량은 0.5~2.0g/ℓ인 것이 바람직 하다.Sodium-2-ethyl-2-octensulfate or the like is used as the anionic compound (penetrant). It is preferable that the addition amount of an anionic compound (penetrant) is 0.5-2.0 g / L.

상기 음이온성 화합물(침투제)은 섬유와 물간의 계면장력을 감소시켜 섬유가 물에 쉽게 젖게하고 물에 녹아있는 알칼리 성분과 섬유와의 접촉을 증진 시킨다. 그 결과 복합섬유 내 용출성분의 가수분해를 균일하고 빠르게 진행시키게 된다.The anionic compound (penetrant) reduces the interfacial tension between the fiber and water, so that the fiber is easily wetted with water and promotes contact with the alkali component and the fiber dissolved in water. As a result, the hydrolysis of the elution component in the composite fiber proceeds uniformly and quickly.

본 발명에 있어서 알칼리 감량처리는 90~105℃에서 30~60분간 실시하는 것이 바람직 하다. In the present invention, the alkali weight loss treatment is preferably performed at 90 to 105 ° C for 30 to 60 minutes.

양이온성 또는 비이온성 화합물을 침투제로 사용하게 되면 감량조건인 강알칼리 분위기 하에서 불용화되어 앞에서 설명한 효과를 얻을 수 없다.When cationic or nonionic compounds are used as penetrants, they are insolubilized in a strong alkaline atmosphere, which is a weight loss condition, and thus the effects described above cannot be obtained.

한편 본 발명에서는 상기 복합섬유 직편물을 알칼리 수용액으로 감량처리할 때, 세정제를 상기 음이온성 화합물(침투제)과 함께 투입하는 것이 더욱 바람직 하다. 세정제로는 한국정밀화학회사의 데몰-RN(Demol-RN, 상표명) 등을 사용할 수 있다.On the other hand, in the present invention, when reducing the composite fiber knitted fabric with an aqueous alkali solution, it is more preferable to add a cleaning agent together with the anionic compound (penetrant). As the cleaner, Demol-RN (trade name) of Korea Fine Chemicals Co., Ltd. may be used.

세정제의 첨가량은 0.5~2.0g/ℓ인 것이 바람직 하다. 세정제는 알칼리 수용액에 녹은 용출성분의 올리고머들을 섬유로 부터 쉽게 탈착하게하고, 탈착된 올리고머들이 다시 섬유에 부착되는 것을 방지하는 역할을 한다.It is preferable that the addition amount of a washing | cleaning agent is 0.5-2.0 g / L. The cleaning agent makes it easy to detach the oligomers of the elution component dissolved in the aqueous alkali solution from the fibers, and prevents the detached oligomers from adhering to the fibers again.
