이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명은 배트(VAT) 염료를 이용하여 기존의 반응성 염료 또는 직접염료에 의한 염색 위주의 색상재현에서 탈피하여 높은 수준의 내광(일광)견뢰도를 발현할 수 있도록 천연 셀룰로오스계 섬유를 염색하는 방법에 관한 것이다.
The present invention is a method for dyeing natural cellulose fibers to express a high level of light fastness (sunlight) by using a bat (VAT) dye to escape from the dye-oriented color reproduction of the existing reactive dyes or direct dyes It is about.
본 발명의 천연셀룰로오스계 섬유의 염색방법은 환원제로서 하이드로설파이트(Na2S2O4) 1~20 g/ℓ 또는 티오우레아디옥사이드 5~20 g/ℓ, 균염제 0.1~2.0 g/ℓ, 분산제 0.1~2.0 g/ℓ, VAT 염료 1~200 g/ℓ, 소다회(Na2CO3) 또는 가성소다(NaOH) 1~20 g/ℓ 및 잔부로써 물이 혼합된 염액에서 침지한 후, 서냉시켜 냉각한 후 수세하는 것이다.The dyeing method of the natural cellulose fibers of the present invention is a hydrosulfite (Na 2 S 2 O 4 ) 1 ~ 20 g / L or thiourea dioxide 5 ~ 20 g / L, a leveling agent 0.1 ~ 2.0 g / L, a dispersant 0.1 to 2.0 g / l, VAT dye 1 to 200 g / l, soda ash (Na 2 CO 3 ) or caustic soda (NaOH) 1 to 20 g / l and the remainder was immersed in the mixed salt solution and then cooled slowly It cools and washes with water.
본 발명의 상기 천연셀룰로오스계 섬유는 한지섬유 또는 대나무섬유인 것이 바람직하다. 우선, 본 발명의 염액은 하이드로설파이트(Na2S2O4) 또는 티오우레아디옥사이드의 환원제를 함유시킴으로써 불용성인 VAT염료를 수용성염료로 환원시켜 천연셀룰로오스계 섬유로의 염착이 용이하게 되도록 한다. The natural cellulose fibers of the present invention is preferably Hanji fiber or bamboo fiber. First, the salt solution of the present invention contains a reducing agent of hydrosulfite (Na 2 S 2 O 4 ) or thiourea dioxide to reduce the insoluble VAT dye to a water-soluble dye to facilitate dyeing into natural cellulose fibers.
상기 염액내에 침지된 섬유와 VAT염료의 화학결합을 위한 환원조건은 알카리 조건하에서 원활하게 일어나므로 소다회 및 가성소다등의 알카리를 함유시킴으로써 VAT염료의 환원성을 높게 한다. pH는 8.0~11.0으로 조절하는 것이 바람직하다. pH 8.0미만이나 pH 11.0초과시에는 환원성 저하로 인해 VAT염료가 섬유로의 염착율이 떨어지거나 또는 너무 강한 알카리 조건에서는 염료의 급착으로 인한 얼룩이 발생할 수 있다. 분산제 및 균염제는 염액내에 침지된 섬유에 VAT염료가 염착할 때 알카리 조건하에서 일어날 수 있는 얼룩 및 불균염이 일어나지 않게 한다.Reducing conditions for chemical bonding of the fiber immersed in the salt solution and the VAT dye occur smoothly under alkaline conditions, thereby increasing the reducibility of the VAT dye by containing alkali such as soda ash and caustic soda. It is preferable to adjust pH to 8.0-11.0. If the pH is lower than 8.0 or higher than pH 11.0, the reduction of reducibility may cause the dyeing rate of the VAT dye to the fiber to be lowered to the fiber or at the extreme alkali condition due to dye impregnation. Dispersants and leveling agents prevent staining and disproportionation that may occur under alkaline conditions when the VAT dye is dyed to the fibers immersed in the salt solution.
본 발명에서는 상기 염액을 1~1.5℃/분의 속도로 승온시켜 90~135℃에서 45~60분동안 천연셀룰로오스계 섬유를 상기 염액에 침지하여 염색하는데, 고압직거(hi-temperature jigger dyeing)에서는 1℃/분정도의 속도로, RAPID(jet dyeing)에서는 1 ~ 1.5℃/분으로 승온시키는 것이 바람직하다. 염액내에서 섬유를 장시간 처리하는 경우에는 섬유속의 중합촉매, 공정 불순물등이 환원하여 소색현상이 유발되므로 45분~60분동안 침지하는 것이 좋다. In the present invention, the salt solution is heated at a rate of 1 ~ 1.5 ℃ / min, and immersed and dyed natural cellulose fibers in the salt solution for 45 to 60 minutes at 90 ~ 135 ℃, hi-temperature jigger dyeing It is preferable to heat up at 1-1.5 degree-C / min in RAPID (jet dyeing) at the speed of about 1 degree-C / min. When the fiber is treated in the salt solution for a long time, the polymerization catalyst of the fiber bundle, the process impurities, etc. are reduced to cause discoloration phenomenon. Soaking for 45 to 60 minutes is preferable.
염액에 침지한 후 -2.0~ -1.5℃/분의 속도로 60~70℃로 냉각, 수세하여 염색을 종료한다. 상기 수세공정은 50~80℃에서 5~30분 동안 기계안에서 온수를 사용하여 수세를 한다. 상기 수세공정에 의하여 섬유 표면에 붙어 있는 미 고착 염료 또는 조제들을 제거할 수 있는데, 잔여 조제들을 확실히 제거해야 후처리공정의 산화 조건에서 산화가 일어남으로 인해 균일한 색상구현이 가능하며, 견뢰도 저하를 방지 할 수 있다.After immersion in the salt solution, the dyeing is completed by cooling to 60-70 ° C and washing with water at a rate of -2.0 to -1.5 ° C / min. The washing process is washed with hot water in the machine for 5 to 30 minutes at 50 ~ 80 ℃. Unfixed dyes or preparations attached to the surface of the fiber can be removed by the washing process, and the remaining preparations must be removed to ensure uniform color due to oxidation under the oxidizing conditions of the post-treatment process, and to reduce the fastness. Can be prevented.
본 발명의 배트(VAT)염료는 환원 염료이므로 다시 산화공정을 거쳐야 본연의 염색된 컬러를 확인 할 수 있다. 따라서 상기 염색공정이 끝난 천연셀룰로오스계 섬유의 후처리인 산화공정은 과산화수소(H202) 0.05~0.1중량%, 빙초산(CH3COOH) 0.05~0.1중량%, 벤조페논계 일광견뢰도 증진제 또는 벤조트리아진계 일광견뢰도 증진제 3~10 중량% 및 잔부로써 물이 혼합된 90~135℃의 후처리액에 침지한 후, 서냉시켜 수세하여 완료하게 된다.The bat (VAT) dye of the present invention is a reducing dye, so it is necessary to go through the oxidation process again to confirm the natural dyed color. Therefore, the oxidation process, which is a post-treatment of the natural cellulose fiber after the dyeing process is hydrogen peroxide (H 2 0 2 ) 0.05 ~ 0.1% by weight, glacial acetic acid (CH 3 COOH) 0.05 ~ 0.1% by weight, benzophenone-based light fastness enhancer or benzo After immersing in a post-treatment solution of 90 ~ 135 ℃ mixed with water with 3 to 10% by weight of triazine-based light fastness enhancer and the balance, it is completed by cooling by slow cooling.
상기 후처리액의 과산화수소(H202)는 환원염색시 포함된 환원제 및 염료를 산화시킴으로써 본연의 고유한 컬러를 구현한다. 상기 빙초산(CH3COOH)은 산성조제로서 염액내에 침지된 섬유와 VAT염료의 화학결합을 위한 환원조건을 위해 첨가된 알카리가 상기 과산화수소(H202)의 산화제 첨가시 발생될 수 있는 pH보정을 위한 것으로서 산화를 용이하게 한다.Hydrogen peroxide (H 2 O 2 ) of the after-treatment liquid implements a unique color by oxidizing the reducing agent and dye included in the reduction dyeing. The glacial acetic acid (CH 3 COOH) is an acidic aid to pH correction that can be generated when the alkali added to the reducing conditions for chemical bonding of the fiber immersed in the salt solution and the VAT dye is added to the hydrogen peroxide (H 2 0 2 ) It is intended to facilitate oxidation.
상기 벤조페논계 또는 벤조트라아진계 일광견뢰도 증진제는 산성욕에서 활발하게 섬유와 결합하며 염료의 결합처럼 섬유내에 결합하여 빛의 난반사등을 통해 염료에 UV(자외선)가 직접적으로 닿지 않도록 함으로써 내광(일광)견뢰도를 높여주는 역할을 한다.
The benzophenone-based or benzotriazine-based light fastness enhancer actively binds to fibers in an acidic bath and binds to fibers like bonds of dyes, so that UV (ultraviolet) light does not directly contact dyes through diffuse reflection of light. Daylight) to increase the fastness.
