Description
본 발명은 열가소성 개질폴리에스터와 열가소성 폴리아마이드를 방사형 복합방사한 4∼20분할형 복합섬유로 구성된 직편물의 피브릴화 및 염색방법에 관한 것이다.The present invention relates to a fibrillation and dyeing method of a woven fabric composed of 4 to 20 split composite fibers in which radially modified spun thermoplastic thermoplastic polyester and thermoplastic polyamide are spun.
특히 분할형 북합섬유로 제조된 직편물을 액류염색기 내에서 적절한 분할제를 사용하여 피브릴화와 염색을 동일욕조에서 진행하여 염색성과 피브릴화율을 향상시키는 방법에 관한 것이다. 종래에는 열가소성 폴리에스터와 열가소성 폴리아마이드로 제조된 분할형 복합섬유로 구성된 직편물의 피브릴화 및 염색을 분리하여 진행하였다.In particular, the present invention relates to a method of improving the dyeing and fibrillation rate of fibrillation and dyeing in the same bath by using a suitable dividing agent in a liquid dyeing machine in a woven fabric made of the split hab fiber. Conventionally, fibrillation and dyeing of knitted fabrics composed of split composite fibers made of thermoplastic polyester and thermoplastic polyamide were performed separately.
즉, 종래에는 복합섬유를 구성성분중 하나 또는 두성분을 화학적으로 용제를 사용하여 팽윤, 수축, 감량을 시켜서 피브릴화를 시켰는데 이러한 방법에 대한 문제점은 용제에 의해 구성성분의 물리적 성질이 심각하게 저하되어 강도, 탄성회복율, 신도 등이 매우 불량하게 되어 의류로 사용하기에는 부적합할 뿐 아니라 피브릴화시키는 용제가 인체독성이 매우 심하고 폐수처리비용이 증가되어 생산비가 높아진다는 단점이 있었다.That is, conventionally fibrillated composite fiber by swelling, shrinking, or reducing one or both of the components chemically using a solvent. The problem with this method is that the physical properties of the components are serious by the solvent. In addition, the strength, elastic recovery rate, elongation, etc. are very poor, which is not suitable for use as clothing, and the fibrillating solvent is very toxic to humans and the waste water treatment cost is increased to increase the production cost.
상기 방법이외의 피브릴화 방법으로는 기계적 충격에 의하여 복합섬유를 분할하기도 하는데 이 방법은 피브릴화율이 낮아서 복합섬유 자체의 목적인 치밀한 표면구조 즉, 부드러운 촉감을 얻을 수 없고 염색시 피브릴화된 섬유와 되지 않은 섬유간의 색상차이가 발생하여 균염제품을 얻을 수 없는 단점이 지적되어 왔다.In addition to the above-described fibrillation method, the composite fiber may be divided by mechanical impact, and this method has a low fibrillation rate, so that it is impossible to obtain a dense surface structure, that is, a soft touch, which is the purpose of the composite fiber itself. It has been pointed out that the color difference between the fiber and the fiber is not obtained, resulting in a homogenized product.
기존의 복합섬유로 구성된 직편물의 제조는 상기 방법으로 피브릴화 공정을 거친 것을 염색하였는데 용제에 의한 피브릴화 공정을 거친 직편물의 경우 염색을 피브릴화와 동일욕조에서 진행할 경우에 피브릴화의 용제로 사용되는 페놀이나 벤질알콜 등이 염료의 용매로도 작용하게 되어 발색성을 떨어뜨리고, 개미산은 염색시 염액을 산성화시켜 염료의 염색성을 손상시키므로 뷸균염이 발생되기 때문에 피브릴화와 염색을 동시에 할 수 없다는 결점이 있었다.In the fabrication of conventional knitted fabrics made of composite fibers, the fibrillation process was dyed by the above method. In the case of the knitted fabrics subjected to the fibrillation process using a solvent, the fibrillation is performed when the dyeing is performed in the same bath as the fibrillation process. Phenolic and benzyl alcohol, which are used as solvents, may also act as solvents for dyes, reducing color development, and formic acid acidizes the salt solution during dyeing, impairing the dyeability of dyes. There was a drawback to not being able to do it at the same time.
상기와 같은 종래의 문제점을 해결하기 위하여 본 발명은 복합섬유의 고유한 광택과 물성을 저하시키지않고 염색성을 향상시키는 분할제를 선정 및 조합하고 동시에 피브릴화 및 염색을 액류염색기에서 실시할수 있는 방법을 개발하게 되었는데 그 내용은 다음과 같다.In order to solve the conventional problems as described above, the present invention selects and combines the dividing agent to improve the dyeability without deteriorating the inherent gloss and physical properties of the composite fiber and at the same time fibrillation and dyeing method in a liquid dyeing machine We have developed the following contents.
동일욕조에서 피브릴화와 염색을 하기 위해서는 무엇보다도 완전한 피브릴화와 합께 염색성에 영향을 주지 않거나 또는 염색성을 향상시킬 수 있는 분할제를 선택 및 조합하는 것이 중요하다. 따라서 본 발명에서는 분할제로 음이온 계면활성제를 사용하고, 주기율표상의 1A 또는 2A족 원소의 설페이트염을 첨가하여 폴리아마이드의 표면장력을 감소시켰으며 분산염료용 캐리어를 염료와 함께 사용하고, 90℃∼l00℃에서 상기 공정을 진행하므로써 복합섬유를 구성하고 있는 열가소성 폴리에스터나 열가소성 폴리아마이드에 상해를 주지 않고 피브릴화와 동시에 염색을 할 수 있었다.In order to fibrillate and dye in the same bath, it is most important to select and combine a dividing agent which can not affect dyeability or improve dyeability in combination with complete fibrillation. Therefore, in the present invention, the anionic surfactant is used as the dividing agent, and the surface tension of the polyamide is reduced by adding the sulfate salt of the 1A or 2A group element of the periodic table, and the carrier for the disperse dye is used together with the dye, and it is 90 ° C. to l00. By proceeding the above process at ℃, it was possible to dye simultaneously with the fibrillation without injuring the thermoplastic polyester or thermoplastic polyamide constituting the composite fiber.
이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
열가소성 개질폴리에스터와 열가소성 폴리아마이드의 방사형 복합방사된 4∼20분할형 복합섬유로 구성된 직편물을 제조함에 있어서, 음이온 계면활성제, 주기율표상의 1A 또는 2A족 원소의 설페이트염 및 분산염료용 캐리어를 병용하여 피브릴화와 염색을 동시에 할 수 있게 되는데, 여기서 열가소성 개질폴리에스터는 하기 구조식 I을 만족하는 금속실폰산염을 함유한 이소프탈레이트 성분이 전체 디액시드의 0.2∼5.0몰%가 함유하게 되는 것이 좋으며, 더욱 좋기로는 0.3∼1.0몰%가 효과적이다. 이때 0.2몰% 미만에서는 피브릴화가 불완전하였고 5.0몰%를 초과해서는 제사가 곤란하였다.In preparing a knitted fabric composed of radially conjugated 4-20 split composite fibers of thermoplastic modified polyester and thermoplastic polyamide, a combination of anionic surfactant, sulfate salt of group 1A or 2A element on the periodic table, and carrier for disperse dyes is used. It is possible to simultaneously fibrillation and dyeing, wherein the thermoplastic modified polyester is preferably an isophthalate component containing a metal silfonate that satisfies the following formula (I) contains 0.2 to 5.0 mol% of the total diacid. More preferably, 0.3 to 1.0 mol% is effective. At this time, the fibrillation was incomplete at less than 0.2 mol%, and it was difficult to make more than 5.0 mol%.
(상기 식중 R은, 수소원자 또는 탄소수 1∼6의 알킬리 또는 아릴기를 나타낸 것이고, M은 알칼리 금속화합물임)(Wherein R represents a hydrogen atom or an alkyl or aryl group having 1 to 6 carbon atoms and M is an alkali metal compound)
본 발명의 대상이 되는 복합섬유의 소재중 열가소성 폴리에스터 부분은 금속설폰산을 함유한 이소프탈레이트 성분을 분자쇄내에 불규칙하게 함유하고 있으므로써 음이온 계면활성제중 알킬소디움술포네이트 또는 아릴알킬소디움술포네이트의 침투가 비교적 빠르고 따라서 열가소성 폴리아마이드와 열가소성 개질폴리에스터의 계면에서 표면장력을 저하시켜 물의 침투 및 확산을 용이하게 하여 피브릴화의 조건을 만들게 된다.The thermoplastic polyester portion of the composite fiber material of the present invention contains an isophthalate component containing a metal sulfonic acid in the molecular chain irregularly, so that an alkyl surfactant sulfonate or an aryl alkyl sodium sulfonate in the anionic surfactant is used. Penetration is relatively fast, thus reducing the surface tension at the interface between the thermoplastic polyamide and the thermoplastic modified polyester, thereby facilitating the penetration and diffusion of water to create the conditions for fibrillation.
여기서 하기 구조식II로 명기되는 음이온 계면활성제의 용액중 농도는 0.01∼0.1중량%가 효율적인데, 0.01중량% 미만에서는 열가소성 개질폴리에스터와 열가소성 폴리아마이드의 계면에서의 표면장력 저하가 낮아 피브릴화율이 낮으며, 0.l중량% 이상에서는 피브릴화와 염색공정상 거품발생으로 인하여 직편물이 공회전하고 거품얼룩이 발생하므로 제품이 불량해진다.Herein, the concentration of the anionic surfactant specified by the following structural formula (II) in the solution is 0.01 to 0.1% by weight, but less than 0.01% by weight of the surface tension at the interface between the thermoplastic modified polyester and the thermoplastic polyamide is low, so the fibrillation rate Low, and more than 0.1% by weight of the product is bad because the knitted fabric idles and bubbles stain due to the foaming in the fibrillation and dyeing process.

(상기 식중 R2는 알킬기 또는 아릴알킬기임)Wherein R 2 is an alkyl group or an arylalkyl group
또한 열가소성 폴리아마이드에 표면장력을 감소시키는 역할을 하는 구조식Ⅲ으로 명기되는 주기율표상의1A 또는 2A족 원소의 염은 0.01∼0.5중량%가 피브릴화에 효율적인데, 0.01중량% 이하에서는 피브릴화율이 낮고, 0.5중량% 이상에서는 피브릴화율의 증가가 없으므로 0.5중량% 이하가 경제적이다.In addition, 0.01 to 0.5% by weight of the salt of an element of 1A or 2A on the periodic table specified in Structural Formula III, which serves to reduce surface tension in thermoplastic polyamide, is effective for fibrillation. It is low, and at 0.5 wt% or more, there is no increase in the fibrillation rate, so 0.5 wt% or less is economical.

캐리어는 열가소성 개질폴리에스터 분자쇄의 결합력을 완화시켜 열운동개시 온도를 저하시키고, 피브릴화온도인 95℃∼100℃에서의 분자쇄 운동성을 크게 하게 되어 복합섬유의 구성소재인 열가소성 개질폴리에스터의 팽윤 및 수축을 높여서 피브릴화율을 향상시킨다. 캐리어로는 2,4-디클로로페놀의 에테르형, 디메틸테레프탈레이트, 메틸디클로로페녹시아세테이트 또는 N-알킬나프탈이미드 유도체 등 분산염료용 캐리어를 적절하게 병용하여 사용한다. 여기서 캐리어의 사용량은 섬유중량에 대하여 0.01∼1.0중량%가 좋은데, 0.01중량% 이하에서는 피브릴화율이 낮고, 1.0중량% 이상에서는 피브릴화율의 증가로 염색얼룩이 발생하므로 0.01∼1.0중량%가 좋다.The carrier reduces the bonding force of the thermoplastic-modified polyester molecular chain to lower the temperature of the onset of thermal motion, and increases the molecular chain mobility at the fibrillation temperature of 95 ° C to 100 ° C. It increases the swelling and shrinkage of the fibrillation rate. As a carrier, carriers for disperse dyes such as ether type of 2,4-dichlorophenol, dimethyl terephthalate, methyldichlorophenoxyacetate or N-alkyl naphthalimide derivatives are appropriately used in combination. Here, the amount of carrier used is preferably 0.01 to 1.0% by weight relative to the weight of the fiber, but 0.01 to 1.0% by weight of the fibrillation rate is low, and more than 1.0% by weight of the fibrillation rate is increased, so 0.01 to 1.0% by weight is good. .
또한 제조공정에서의 적합한 온도조건은 90℃∼100℃로 하는 것이 좋은데, 이는 90℃ 이하에서는 염색농도 및 피브화율이 낮으며, 100℃ 이상에서는 고압에서 진행하므로 설비요건 및 공정시간과 에너지 비용이높고 피브릴화율의 증가가 미소하고 색상의 농도증가가 거의 없으므로 90℃~100℃에서 직편물을 제조하는 것이 효율적이다.In addition, the suitable temperature conditions in the manufacturing process is preferably from 90 ℃ to 100 ℃, which is low dyeing concentration and fibrillation rate below 90 ℃, and proceeds at high pressure above 100 ℃, equipment requirements, processing time and energy costs It is efficient to manufacture knitted fabrics at 90 ° C to 100 ° C because it is high, the increase in fibrillation rate is small, and there is little increase in color density.
따라서 용제에 의한 복합섬유의 팽윤 및 수축에 의한 피브릴화 방법에서 발생되는 복합섬유의 용해 및 상해를 본 발명에서는 비용제형 분할제를 사용함으로서 복합섬유의 물성을 보존할 수 있을 뿐만 아니라 분할제로 사용되는 캐리어는 분산염료의 염색을 촉진시켜 발색성을 높여 주며, 알킬소디움설포네이트 또는 아릴알킬소디움실포네이트는 분산염료의 분산제 및 균염제의 역할을 하므로 염색시 별도의 계면활성제를 첨가하지 않아도 되며, 주기율표상의 1A 또는 2A족 원소의 설페이트염은 산성 염료의 열가소성 폴리아마이드에 대한 균염제 역할을 하므로 선정된 분할제가 모두 염색성을 향상시켜 염색농도를 높이고 군염성을 향상시키며 공정조건이 상압에서 진행되고 피브릴화와 동시에 염색을 하므로써 공정시간과 에너지 절감으로 제조비용을 줄일 수 있었다.Therefore, in the present invention, the dissolution and injury of the composite fiber generated in the fibrillation method by the swelling and shrinkage of the composite fiber by the solvent can not only preserve the physical properties of the composite fiber but also use it as a splitting agent Carrier to promote the dyeing of the disperse dyes to improve the color development, alkyl sodium sulfonate or aryl alkyl sodium silfonate acts as a dispersant and leveling agent of the disperse dyes do not need to add a separate surfactant during dyeing, Sulfate salts of Group 1A or 2A elements act as homogenizers for thermoplastic polyamides of acid dyes, so all selected splitting agents improve dyeability, increase dyeing concentration, improve group saltability, and process conditions proceed at atmospheric pressure. Simultaneous dyeing to reduce manufacturing time and energy It could be reduced.
본 발명에서 사용된 염료로는 담색의 경우 분산염료 단독으로 염색하였고 중색 및 농색은 분산염료와 금속착염 산성염료를 1 : 2의 비율로 사용하였다. 본 발명에 의해 복합섬유를 피브릴화 및 염색함으로서 얻어지는 효과는 복합섬유의 피브릴화율을 고수율로 획득하면서 직편물의 고유한 탄성회복율, 인열강도, 인장강도의 저하가 없는 물성을 발휘할 수 있고, 페놀이나 벤질알콜 유화액의 사용에 비하여 공정조작성이 단순하그 안전성이 높으여 폐수의 발생이 거의 없고, 염색과 피브릴화를 동일 욕조에서 처리함으로서 공정이 단축되고 에너지가 절감되며 염색농도가 높고 균염성이 향상된다.As the dye used in the present invention, in the case of pale color, only the disperse dye was dyed, and in the case of the neutral and the deep color, the disperse dye and the metal complex acid dye were used in a ratio of 1: 2. The effect obtained by fibrillating and dyeing the composite fiber according to the present invention can obtain the fibrillation rate of the composite fiber in high yield, and can exhibit physical properties without lowering the intrinsic elastic recovery rate, tear strength, and tensile strength of the knitted fabric. Compared to the use of phenol or benzyl alcohol emulsions, the process is simpler and the safety is higher.Therefore, there is almost no waste water generation. The leveling property is improved.
본 발명은 복합섬유를 트리코트, 랏셀, 평직, 능직, 이중직 기모지 등으로 사용할 때 높은 피브릴화율을 얻을 뿐만 아니라 직편물 고유의 물성을 보존하여 우수한 제품을 얻을 수 있다. 이하 본 발명의 실시예와 비교예를 설명하면 다음과 같다.The present invention can obtain a superior product by not only high fibrillation rate but also preserving the inherent physical properties of the woven fabric when using the composite fibers as tricot, ratsel, plain weave, twill, double weave brushing paper. Hereinafter, examples and comparative examples of the present invention will be described.
실험에서 사용된 복합섬유는 구조식 I중 R1=CH3, M=Na 의 것으로 전체 디액시드의 0.5몰% 함유된 열가소성 개질폴리에스터와 열가소성 폴리아마이드가 70 : 30의 구성비를 가진 방사형 17분할형 80D/36F를 32게이지로 트리코트 제편한 편물을 사용하였다. 제조공정은 염료를 분산염료로 일본화약제품인 카야론 블렉EX-SF를 5섬유중량%, 산성염료로 영국 아이.씨.아이 제품인 뉴트리크롬 블랙S-BN을 4섬유중량%를 사용하고, 액류염색기에서 연수(栽氷)를 사용하여 빙초산으로 pH를 5.0으로조절하였고, 본 발명의 특허청 '구범위 조건과 같은 분할용액으로 편물의 1회전 시간이 60초, 액비 20 : 1로 하여 40℃에서 98℃까지 20분간 승온시켜 98℃에서 40분간 유지하였다.The composite fibers used in the experiment were R 1 = CH 3 and M = Na in the formula I, and the radial 17-segment type having a composition ratio of 70:30 of thermoplastic modified polyester and thermoplastic polyamide containing 0.5 mol% of the total diacids A tricot knit knitted fabric with 80 gauges of 80D / 36F was used. The manufacturing process uses dyes as disperse dyes, 5% by weight of the Japanese chemical Kayalon Bleck EX-SF, and 4% by weight of UK fiber NUTRICROM Black S-BN as acid dyes. PH was adjusted to 5.0 using soft water in glacial acetic acid, and one rotation time of the knitted fabric was divided into the same solution as the patent office's nine-range conditions in 60 seconds and the liquid ratio 20: 1 to 98 at 40 ° C. It heated up to 20 degreeC and hold | maintained for 40 minutes at 98 degreeC.
이후50℃까지 24분간 강온시킨 후 수세하여 물성을 측정하였다.Then, the temperature was lowered to 50 ° C. for 24 minutes and washed with water to measure physical properties.
