Description
본 발명은 폴리비닐클로라이드 섬유를 분산 염료로 염색하는 방법에 관한 것으로서, 특히 저온에서 높은 색농도로 촉감의 손상없이 폴리비닐클로라이드 섬유를 염색하는 방법에 대한 것이다.The present invention relates to a method of dyeing polyvinylchloride fibers with disperse dyes, and more particularly to a method of dyeing polyvinylchloride fibers without damage to the touch at low temperatures and high color concentration.
일반적으로 폴리비닐클로라이드 섬유의 경우는 부드러운 촉감으로 인해 어린이용 의류, 모포, 카페 등에 자주 사용되어 왔으며, 최근에는 여성용 가발 등으로 그 이용 영역을 확대되고 있다. 그러나, 폴리비닐클로라이드는 습열 처리에 매우 민감하며, 90℃ 이상의 온도에서는 급격한 수축으로 인하여 촉감이 매우 딱딱해지는 단점을 안고 있다. 이러한 단점으로 염색 온도에 큰 제한을 받아 왔으며, 또한 저온에서 염색시 폴리비닐클로라이드 섬유에 대한 분산 염료의 염착이 매우 떨어지기 때문에 고농도의 색을 발현하기가 매우 어려웠다. In general, polyvinyl chloride fibers have been frequently used in children's clothing, blankets, cafes, etc. due to their soft touch, and recently, the use area of women's wigs has been expanded. However, polyvinyl chloride is very sensitive to wet heat treatment, and has a disadvantage in that the touch becomes very hard due to rapid shrinkage at a temperature of 90 ° C. or higher. Due to these drawbacks, the dyeing temperature has been severely limited, and since dyeing of the disperse dyes to the polyvinyl chloride fibers is very poor when dyeing at low temperatures, it is very difficult to express high concentration colors.
따라서, 상기 과제를 해결하기 위한 본 발명의 목적은 폴리비닐클로라이드 섬유를 낮은 온도에서 높은 색농도로 염색하며, 염색후 섬유의 촉감을 손상하지 않는 염색방법을 제공하는데 있다. Accordingly, an object of the present invention for solving the above problems is to provide a dyeing method of dyeing polyvinyl chloride fibers at a high color concentration at a low temperature, and does not impair the touch of the fibers after dyeing.
본 발명에 의하면 폴리비닐클로라이드 섬유를 분산염료를 사용하여 염색하는 방법에 있어서, 디에틸프탈레이트형 캐리어 및 알킬벤젠형 캐리어로 이루어진 군에서 선택되는 1종 이상의 캐리어를 0.1∼5g/ℓ의 농도로 첨가하여 50∼90℃에서 염색한 후, 95∼135℃에서 건열처리 하는 것을 특징으로 하는 폴리비닐클로라이드 섬유의 염색방법이 제공된다.According to the present invention, in the method of dyeing polyvinyl chloride fibers using a disperse dye, at least one carrier selected from the group consisting of a diethylphthalate carrier and an alkylbenzene carrier is added at a concentration of 0.1 to 5 g / l. After the dyeing at 50 ~ 90 ℃, dry dyeing at 95 ~ 135 ℃ is provided a method for dyeing polyvinyl chloride fibers.
이하, 본 발명을 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in detail.
본 발명은 분산 염료를 사용하여 폴리비닐클로라이드 섬유를 염색함에 있어서 디에틸프탈레이트형 캐리어 및 알킬벤젠형 캐리어로 이루어진 군에서 선택되는 1종 이상의 캐리어를 0.1∼5g/ℓ의 농도로 첨가하여 50∼90℃에서 염색한 후, 95∼135℃에서 건열처리 하는 것으로 이러한 방법은 촉감의 손상 없이 높은 색농도의 폴리비닐클로라이드 섬유를 얻는 염색방법이다.In the present invention, in dyeing polyvinyl chloride fibers using a disperse dye, at least one carrier selected from the group consisting of a diethylphthalate-type carrier and an alkylbenzene-type carrier is added at a concentration of 0.1 to 5 g / L, and then 50 to 90. After the dyeing at ℃ ℃ and dry heat treatment at 95 ~ 135 ℃ This method is a dyeing method to obtain a polyvinyl chloride fiber of high color concentration without damage to the touch.
본 발명은 디에틸프탈레이트형 캐리어 및 알킬벤젠형 캐리어로 이루어진 군에서 선택되는 1종 이상의 캐리어를 0.1∼5g/ℓ의 농도로 첨가하여 50∼90℃에서 염색한 후, 95∼135℃에서 건열처리 하는 것을 특징으로 한다.In the present invention, one or more carriers selected from the group consisting of diethylphthalate-type carriers and alkylbenzene-type carriers are added at a concentration of 0.1-5 g / l and dyed at 50-90 ° C., followed by dry heat treatment at 95-135 ° C. Characterized in that.
본 발명에서 사용되는 캐리어로는 방향족 탄화수소가 사용될 수 있으며, 그 중 디에틸 프탈레이트 계통 또는 알킬벤젠형의 캐리어가 바람직하다. 본 발명에서는 디에틸프탈레이트형 캐리어 및 알킬벤젠형 캐리어로 이루어진 군에서 선택되는 1종 이상의 캐리어가 사용될 수 있다. 첨가하는 캐리어는 염색할 폴리비닐클로라이드 섬유와 염료를 칙량하여 준비한 후 미리 물에 희석한 후 투입하는 것이 바람직하다. 혼합하여 사용할 때에는 어느 것이든 먼저 물에 희석한 후 충분한 교반을 통해 안정한 유화액을 형성한 뒤에 투입하는 것이 바람직하다.As the carrier used in the present invention, an aromatic hydrocarbon may be used, of which a diethyl phthalate-based or alkylbenzene type carrier is preferable. In the present invention, one or more carriers selected from the group consisting of diethylphthalate carriers and alkylbenzene carriers may be used. The carrier to be added is prepared by weighing the polyvinyl chloride fiber and the dye to be dyed, and diluting it in water beforehand. When mixed and used, it is preferable to dilute with water first, and to add after forming a stable emulsion through sufficient stirring.
또한, 균일한 염색을 위한 캐리어의 사용량은 염색 온도, 염색물의 색농도, 염료의 성질 등에 따라 달라 질 수 있으나, 본 발명에서는 0.1∼5g/ℓ의 농도로 첨가하는 것이 바람직하다. 더욱 바람직하기로는 1∼3.5g/ℓ의 농도이다. 농도가 너무 낮으면 원하는 색농도를 얻기가 힘들며, 너무 높을 경우 섬유로부터 잔류하는 캐리어를 제거하기가 어려워져 바람직하지 않다. In addition, the amount of carrier used for uniform dyeing may vary depending on the dyeing temperature, the color concentration of the dye, the nature of the dye, etc. In the present invention, it is preferable to add at a concentration of 0.1 ~ 5g / ℓ. More preferably, the concentration is 1 to 3.5 g / l. If the concentration is too low, it is difficult to obtain the desired color concentration, and if too high, it is difficult to remove the residual carrier from the fibers, which is undesirable.
폴리비닐클로라이드 섬유를 분산염료로 염색할때에는 일반적으로 널리 알려진 분산염료의 흡진염법을 이용하여 염색하는 것이 바람직하다.When dyeing polyvinyl chloride fibers with a disperse dye, it is generally preferable to dye using a well-known method of reducing salts of disperse dyes.
본 발명은 저온에서 균염성 캐리어의 존재하에 분산염료로 염색하는 것이 가능하다. 본 발명의 염색온도는 50∼90℃가 바람직하다. 더욱 바람직하기로는 60∼65℃이다. 이와 같은 저온에서 염색하기 때문에 섬유의 수축이 거의 일어 나지 않아 섬유 촉감의 손상이 거의 일어 나지 않는다.The present invention is capable of dyeing with a disperse dye in the presence of a leveling carrier at low temperatures. As for the dyeing temperature of this invention, 50-90 degreeC is preferable. More preferably, it is 60-65 degreeC. Since dyeing at such a low temperature, the shrinkage of the fiber hardly occurs, so that damage to the fiber feel is hardly caused.
염색후 섬유 내에 잔류하는 캐리어는 후수세 및 95∼135℃의 건열처리 공정을 통하여 제거할 수 있다. The carrier remaining in the fiber after dyeing can be removed through post-washing and dry heat treatment at 95-135 占 폚.
염색 후에 염색물은 깨끗이 세척한 다음, 70∼75℃의 온도에서 건조하여 섬유에 잔존하는 수분을 제거한다. After dyeing, the dye is washed thoroughly, and then dried at a temperature of 70 ~ 75 ℃ to remove the moisture remaining in the fiber.
본 발명에서는 건조시킨 섬유를 95∼135℃에서 건열처리 하는 것이 바람직하다. 더욱 바람직하기로는 110∼120℃이다. 이러한 건열처리 공정을 통하여 섬유 내에 잔존하는 균염성 캐리어는 완전히 제거되게 된다. 상기의 온도 범위를 벗어나서 건열처리를 하게되면 섬유의 촉감이 나빠지고 잔존 캐리어가 완전하게 제거되지 않아 바람직하기 않다.In this invention, it is preferable to dry-dry the dried fiber at 95-135 degreeC. More preferably, it is 110-120 degreeC. Through this dry heat treatment process, the uniform carrier remaining in the fiber is completely removed. Dry heat treatment outside the above temperature range deteriorates the feel of the fiber and is not preferable because the residual carrier is not completely removed.
염색되는 폴리비닐클로라이드 섬유는 다양한 형태, 즉, 원사, 직물, 환편물, 벨벳 등으로 염색이 실시 될 수 있는데 이는 완제품의 최종 용도에 따라 달라질 수 있다. 본 발명에 따라 염색에 사용된 균염성 캐리어를 완전히 제거한 염색물은 제반 견뢰도 측면에서 매우 우수하며, 특히 일광 견뢰도 및 세탁 견뢰도에서 우수하다.The polyvinylchloride fibers to be dyed can be dyed in various forms, ie yarns, fabrics, circular knits, velvets, and the like, depending on the end use of the finished product. The dyeings completely removed from the leveling carrier used in the dyeing according to the present invention are very excellent in terms of overall fastness, particularly in light fastness and washing fastness.
이하, 본 발명의 실시예를 들어 상세히 기술하고자 한다. 단, 본 발명은 이들 특정 실시예에 의해 제한되지 않는다.Hereinafter, an embodiment of the present invention will be described in detail. However, the present invention is not limited by these specific examples.

수분을 완전히 제거한 폴리비닐클로라이드 필라멘트를 120℃에서 무장력하에 스텐터(Stenter,마디스(Mathis)사, 스위스)로 1분간 건열처리 하였다. 단, 비교예들의 경우에는 상기한 건열처리를 생략하였다.The polyvinyl chloride filament from which water was completely removed was dried and heat-treated with a stenter (Stenter, Mathis, Switzerland) for 1 minute under no tension at 120 ° C. However, in the case of the comparative examples, the above dry heat treatment was omitted.

염색 온도 60℃, 캐리어 농도 2g/ℓ에서 염색한 염색물의 색농도를 100으로 평가하고 다른 염색물의 색농도를 상대적인 수치로 나타낸다. 색농도의 측정은 분광광도계(컬러-아이 7000에이(Color-Eye 7000A), 멕베스(Macbeth)사)로 측정한 염색 샘플의 반사율로부터 K/S값을 계산하여 얻었다. The color concentration of the dyed dye was evaluated as 100 at a dyeing temperature of 60 ° C. and a carrier concentration of 2 g / L, and the color density of the other dye was expressed as a relative value. The measurement of the color concentration was obtained by calculating the K / S value from the reflectance of the dyed sample measured with a spectrophotometer (Color-Eye 7000A, Macbeth).
2) 섬유의 촉감 변화2) changes in the feel of the fibers
염색전 폴리비닐클로라이드 필라멘트 샘플을 기준으로 염색후 촉감의 변화를 부드러움(○), 딱딱함(×)으로 구분하여 나타내었다.Based on the polyvinyl chloride filament sample before dyeing, the change of the touch after dyeing was expressed as softness (○) and hardness (×).
