Description
본 발명은 내열성 및 염색성이 우수한 투-웨이(Two-way) 편물의 제조방법에 관한 것으로서, 보다 구체적으로는 염색된 편물 생지를 최종열처리 직전에 내열성 향상제가 물에 용해된 패딩액으로 처리하여 내열성 및 염색성이 향상된 투-웨이 편물을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a two-way knitted fabric having excellent heat resistance and dyeing resistance. More specifically, the dyed knitted fabric is treated with a padding liquid in which a heat resistance enhancer is dissolved in water immediately before the final heat treatment. And a method of making a two-way knit with improved dyeability.
이하, 본 발명에 따른 투-웨이 편물은 스판덱스(spandex)원사와 나일론 원사를 함께 제편하여 양방향으로 뛰어난 신축성을 부여한 편물을 나타내며, 투-웨이 편물은 주로 수영복 원단, 여성 란제리 등으로 사용된다.Hereinafter, the two-way knitted fabric according to the present invention represents a knitted fabric obtained by spunding a spandex yarn and a nylon yarn together to give excellent elasticity in both directions, and the two-way knitted fabric is mainly used as a swimsuit fabric, a female lingerie, and the like.
상기 투-웨이 편물은 이를 구성하는 스판덱스 원사의 신축성을 고정시키기 위해 도 1에서 도시된 바와 같이 염색공정 전 또는 후에 약 190~200℃의 고온에서 열고정하는 예비열고정(Pre-setting) 공정과 최종열고정(Final setting) 공정을 거쳐야 한다.The two-way knitted fabric is a pre-setting process and a final heat of heat setting at a high temperature of about 190 ~ 200 ℃ before or after the dyeing process as shown in Figure 1 to fix the elasticity of the spandex yarn constituting it Final setting must be done.
상기 열고정 공정들에서 내열성이 열고정 온도보다 낮은 나일론 원사는 물성 변화를 일으키고, 이로 인해 염색공정에서 미염착과 경선발생 등의 문제를 유발하는 문제가 있었다.In the heat setting processes, nylon yarns having heat resistance lower than the heat setting temperature cause a change in physical properties, thereby causing problems such as undyed and meridion in the dyeing process.
상기 미염착과 경선발생 문제들은 나일론 원사의 내열성 및 염색과 관계가 있다. 또한, 투-웨이 편물 제조시 생산속도를 높이기 위해서 상기 열고정 온도를 점차 높게 설정하려는 경향이 많아 상기와 같은 문제는 향후 더욱 심각하게 발생될 것으로 예상된다.The undyed and meridional problems are related to the heat resistance and dyeing of nylon yarns. In addition, there is a tendency to set the heat setting temperature gradually higher in order to increase the production speed during the production of two-way knit fabric, such problems are expected to occur more seriously in the future.
이와 같은 문제점들을 해결하기 위해서 투-웨이 편물 제조시 사용되는 나일론 폴리머 제조시 중합단계에서 다양한 내열성 향상제를 첨가하여 나일론 원사의 내열성을 향상시키는 방법들이 시도되었으나, 상기 종래방법은 내열성 향상제가 원사 단면의 전체면적에 걸쳐 고르게 분산되기 때문에 원하는 내열성 개선 효과를 얻기 위해서는 다량의 내열성 향상제를 첨가해야 되어 나일론 원사의 제조원가가 너무 상승하는 문제로 상업화에는 한계가 있었다.In order to solve these problems, methods for improving the heat resistance of nylon yarns have been attempted by adding various heat resistance enhancers in the polymerization step in the production of nylon polymers used in the manufacture of two-way knit fabrics. Since it is evenly distributed over the entire area, in order to obtain the desired heat resistance improving effect, a large amount of heat resistance improving agent has to be added, and the production cost of nylon yarn has been so high that the commercialization was limited.
또 다른 종래기술로는 투-웨이 편물 제조시 사용되는 나일론 원사를 방사할때 방사되는 원사 표면을 내열제 향상제가 용해된 방사유제로 처리해 타일론 원사의 내열성을 개선하는 방법도 있으나, 이 경우 원사표면에 묻은 상기 방사유제가 편물 생지의 가공공정중 하나인 리렉스(Relax) 공정에서 불균일하게 제거되기 때문에 이후 실시되는 열고정(Setting) 공정에서 만족할만한 내열성을 발현하지 못해 결국 경선발생 등의 염색 불균일이 일어나는 문제가 있다.Another conventional technique is to improve the heat resistance of the tylon yarn by treating the surface of the yarn to be spun when the spinning yarn nylon yarn used in the manufacture of two-way knit yarn with a heat-dissipating agent dissolved heat-resistant agent, in this case yarn Since the spinning oil on the surface is removed unevenly in the Relax process, which is one of the processes of knitting dough, it does not express satisfactory heat resistance in the subsequent setting process, and thus dyes such as meridians. There is a problem of non-uniformity.
본 발명의 목적은 이와 같은 종래 문제점들을 해결하기 위한 것으로서, 투-웨이 편물이 가공공정 중에도 계속 우수한 내열성 및 염색성을 발현하여 경선발생 등의 염색불균일 문제가 없는 투-웨이 편물을 제공하기 위한 것이다.SUMMARY OF THE INVENTION An object of the present invention is to solve such conventional problems, and to provide a two-way knitted fabric that has two-way knitted fabrics that continue to express excellent heat resistance and dyeability even during a processing process, so that there is no dye non-uniformity problem such as meridian generation.
본 발명은 투-웨이 편물 생지가 가공공정 중에도 계속 우수한 내열성을 발현하여 미염색이나 경선발생 등의 문제를 억제하도록 염색된 편물 생지를 최종열고정하기 바로 직전에 내열성 향상제가 용해된 패딩액에 패딩(Padding) 처리하는 방법을 제공한다.The present invention padding the padding liquid in which the heat resistance enhancer was dissolved immediately before the two-way knitted dough continued to express the excellent heat resistance even during the processing process, and immediately dyed the knitted dough dyed to suppress problems such as undyed or meridians. Padding) provides a method for processing.
이하 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail.
본 발명에 따른 투-웨이 편물의 제조방법은 염색된 편물을 최종열고정(Final-setting)하기 전에 물 또는 나일론 원사용 방사유제에 음이온계 계면활성제, 양쪽성 계면활성제 및 하기 구조식(Ⅰ)의 1,3-벤젠디카르복아미드,N,N'-비스(2,2,6,6-테트라메틸-4-페리딜) [1,3-benzendicarboxamide,N,N'-bis(2,2,6,6-tetramethyl-4-pheridyl)] 중에서 선택된 1종 이상을 포함하는 내열성 향상제가 용해되어 있는 패딩액으로 패딩(Padding)처리하는 것을 특징으로 한다.Method for producing a two-way knitted fabric according to the present invention is an anionic surfactant, amphoteric surfactant, and 1 of the following structural formula (I) in water or nylon-based spinning oil prior to final-setting the dyed knitted fabric , 3-benzenedicaramide, N, N'-bis (2,2,6,6-tetramethyl-4-ferridyl) [1,3-benzendicarboxamide, N, N'-bis (2,2,6 , 6-tetramethyl-4-pheridyl)] is characterized in that the padding treatment is performed with a padding solution in which a heat resistance enhancer including at least one selected from the group is dissolved.
통상적으로, 투-웨이 편물 생지를 가공하는 방법은 도 1에 도시된 바와 같이 (ⅰ) 편물 생지를 온수에 침지하여 표면에 묻어 있는 방사유제를 제거하는 리렉스(Relax) 공정과, (ⅱ) 리렉스 공정을 거친 편물 생지를 약 190~200℃의 온도에서 처리하는 예비열고정(Pre-setting) 공정과, (ⅲ) 예비열고정된 편물 생지를 염색하는 공정과, (ⅳ) 염색된 편물을 약 190~200℃의 온도에서 처리하는 최종열고정(Final-setting) 공정을 차례로 실시하는 것이다.Typically, a method of processing a two-way knit dough includes a (Relax) process of removing the spinning oil on the surface by (i) immersing the knit dough in hot water as shown in Figure 1, and (ii) A pre-setting process for treating knitted fabrics subjected to the Relex process at a temperature of about 190 to 200 ° C., (i) a process for dyeing pre-heated knitted fabric dough, and (i) a dyed knit fabric It is to perform a final heat-setting (final-setting) process in order to treat at a temperature of about 190 ~ 200 ℃.
도 1은 본 발명에 따른 공정 플로우 차트의 일례이다.1 is an example of a process flow chart according to the present invention.
상기 편물 생지에는 편물 생지의 전체중량을 기준으로 약 1.8중량%의 방사유제가 묻어 있으며, 이를 리렉스 공정으로 처리하면 상기 방사유제의 절반정도가 불균일하게 제거된다.The knitted dough is embedded with about 1.8% by weight of a spinning emulsion based on the total weight of the knitting dough, and when processed by the Relex process, about half of the spinning emulsion is unevenly removed.
따라서, 내열성 및 염색성 향상을 위해 앞에서 설명한 종래기술과 같이 투-웨이 편물 제조용 나일론 원사를 방사할때 내열제 향상제가 용해된 방사유제를 방사되는 원사 표면에 코팅처리하는 경우에는, 나일론 원사 표면에 묻은 상기 방사유제가 상기 편물의 가공공정중 하나인 리렉스 공정에서 불균일하게 제거되기 때문에 이후 실시되는 예비열고정 공정, 염색공정 및 최종열고정 공정에서 원하는 내열성을 발현하지 못하여 결국 미염착이나 경선발생 등과 같은 염색불균일 문제가 발생 되게 된다.Therefore, when spinning a nylon yarn for two-way knit fabrication as described in the prior art for improving heat resistance and dyeing resistance, when the spinning oil dissolved in the heat-resistant agent is coated on the surface of the spinning yarn, it is applied to the surface of the nylon yarn. Since the spinning oil is unevenly removed in the Relex process, which is one of the processing processes of the knitted fabric, it does not express desired heat resistance in the preliminary heat fixing process, the dyeing process, and the final heat fixing process. Dyeing non-uniformity problem will occur.
본 발명에서는 상기와 같은 문제점을 해소하기 위해서 상기 리렉스 공정과 염색공정을 거친 편물을 최종열고정하기 바로 직전에 물에 음이온계 계면활성제인 내열성 향상제가 용해되어 있는 패딩액으로 패딩처리하여 이후 실시되는 최종열고정 공정에서도 원하는 내열성이 계속 발현되도록 함으로서 미염착이나 경선발생 등과 같은 염색불균일 문제를 해소한다.In the present invention, in order to solve the above problems, the padding treatment is performed with a padding solution in which a heat resistance enhancer, an anionic surfactant, is dissolved in water immediately before the final heat fixation of the knitted fabric which has undergone the Relex process and dyeing process. Even in the final heat fixation process, the desired heat resistance is continuously expressed to solve dyeing non-uniformity problems such as undyed or meridians.
상기 리렉스 공정은 제조된 편물 생지에 포함된 유제 및 이물질은 제거하고 물에 의해 편물 생지의 수축을 간단히 고정(Setting)하는 공정으로서, 편물 생지가 물에 담겨져 있다.The relex process is a process of simply setting the shrinkage of the knit dough by removing the oil and foreign substances contained in the manufactured knit dough, and the knit dough is contained in water.
5~6단 정도의 욕조를 25~30 m/분 정도의 속도로 60~90초 동안 통과시키는 방법으로 실시한다.The 5-6 stage bathtub is passed through at a speed of 25-30 m / min for 60-90 seconds.
첫번째 욕조의 물 온도는 85℃ 정도로 하고, 6번째 욕조로 갈수록 각 욕조의 물 온도가 점차 낮아지도록하고, 6번째 욕조의 물 온도는 상온으로 하는 것이 바람직하다.The water temperature of the first bath is about 85 ℃, the water temperature of each bath is gradually lowered toward the sixth bath, the water temperature of the sixth bath is preferably at room temperature.
상기 예비열고정 공정은 텐터(Tenter)를 이용하여 편물 생지를 열고정시키는 공정으로서, 온도는 180~195℃로 하고, 통과속도는 30m/분 수준으로 하는 것이 바람직하다.The preliminary heat fixing process is a process of heat-setting the knitted fabric using a tenter, the temperature is 180 ~ 195 ℃, the passing speed is preferably set to 30m / min level.
상기 염색공정은 레피어(Rapier) 염색기를 사용하여 통상적인 염색 방법 및 조건으로 실시한다.The dyeing process is carried out in a conventional dyeing method and conditions using a Rapier dyeing machine.
상기 최종열고정 공정은 예비열고정 공정과 동일하게 실시하며, 용도에 따라 서는 유연제, 흡습제 등을 편물에 처리할 수도 있다.The final heat fixation step is performed in the same manner as the preliminary heat fixation step, and depending on the use, a softener, a moisture absorbent, or the like may be treated on the knitted fabric.
본 발명은 상기 각 공정들의 통과속도, 온도 등 처리조건과 처리방법을 특별하게 한정하는 것은 아니다.The present invention does not specifically limit treatment conditions and treatment methods such as passing speed, temperature, and the like of the above processes.
상기 패딩액내에 용해되어 있는 음이온계 계면활성제인 내열성 향상제의 함량은 0.05~5중량%인 것이 바람직하다.It is preferable that the content of the heat resistance improving agent which is an anionic surfactant dissolved in the said padding liquid is 0.05 to 5 weight%.
상기 함량이 0.05중량% 미만일 경우에는 내열성 및 염색성 향상 효과가 미미하게 되어 투-웨이 편물 제조시 경선 및 미염착 현상이 발생되고, 5중량%를 초과하는 경우에는 패딩액의 점도가 상승하여 이를 편물 생지 표면에 패딩하는 공정이 어렵게 된다.When the content is less than 0.05% by weight, the effect of improving heat resistance and dyeing property is insignificant. Padding on the dough surface becomes difficult.
상기 패딩(Padding) 공정은 편물 생지를 패딩액 내에 침지시킨 후 이를 스퀴징 로울러로 스퀴징시켜주는 공정들로 이루어진다.The padding process consists of immersing the knitted fabric in the padding liquid and squeezing it with a squeegee roller.
상기 내열성 향상제의 구체적인 예로는 음이온계 계면활성제인 일본 마츠모토 유시 세이야쿠(Matsumoto Yushi Seiyaku) 주식회사의 상품명 KMN-2011, 양쪽성 계면활성제인 다케모토 오일 앤드 패트(Takemoto Oil & Fat) 주식회사의 상품명 KIN-436 또는 상기 구조식(I)의 1,3-벤젠디카르복아미드, N,N'-비스(2,2,6,6-테트라메틸-4-페리딜) [1,3-benzendicarboxamide, N,N'-bis(2,2,6,6-tetramethyl-4-pheridyl)] 등이 사용된다.Specific examples of the heat resistance improving agent include the trade name KMN-2011 of Matsumoto Yushi Seiyaku Co., Ltd., an anionic surfactant, and the trade name KIN-436 of Takemoto Oil & Fat Co., Ltd., an amphoteric surfactant. Or 1,3-benzenedicarboxamide of structure (I), N, N'-bis (2,2,6,6-tetramethyl-4-ferridyl) [1,3-benzendicarboxamide, N, N ' -bis (2,2,6,6-tetramethyl-4-pheridyl)] and the like are used.
상기 구조식(I)의 1,3-벤젠디카르복아미드, N,N'-비스(2,2,6,6-테트라메틸-4-페리딜) [1,3-benzendicarboxamide, N,N'-bis(2,2,6,6-tetramethyl-4-pheridyl)]은 나일론 원사용 방사유제에 용해시켜 코팅용 원액을 제조하고, 상기 음이온계 계 면활성제와 양쪽성 계면활성제는 물에 용해시켜 코팅용 원액을 제조한다.1,3-benzenedicarboxamide, N, N'-bis (2,2,6,6-tetramethyl-4-ferridyl) of the above formula (I) [1,3-benzendicarboxamide, N, N'- bis (2,2,6,6-tetramethyl-4-pheridyl)] is dissolved in nylon spinning yarn to prepare a coating solution, and the anionic surfactant and amphoteric surfactant are dissolved in water and coated. Prepare a stock solution.
상기와 같은 본 발명의 제조방법으로 제조된 투-웨이 편물은 나일론 원사와 스판텍스 원사로 구성되고, 편물 표면에 내열성 향상제가 용해되어 있는 패딩액이 코팅되어 있고, 190℃에서 10분간 열처리시의 황변지수(Yellow Index)가 1~20이며, 190℃에서 10분간 열처리시의 색차인 K/S값이 5.2~6.1 이다.The two-way knitted fabric produced by the method of the present invention as described above is composed of a nylon yarn and a spantex yarn, and is coated with a padding liquid in which a heat resistance enhancer is dissolved on the surface of the knitted fabric, and is subjected to heat treatment at 190 ° C. for 10 minutes. Yellow Index is 1 ~ 20 and K / S value is 5.2 ~ 6.1, which is the color difference after heat treatment at 190 ℃ for 10 minutes.
상기 황변지수가 상기 범위보다 낮은 경우에는 내열성이 부족하여 염색 불균일이 쉽게 발생되고, 색차인 K/S값이 상기 범위를 벗어나면 외관 등이 저하된다.When the yellowing index is lower than the above range, the heat resistance is insufficient and dyeing unevenness easily occurs, and when the K / S value, which is the color difference, is out of the above range, the appearance is degraded.
본 발명에 있어서 황변지수와 K/S값은 컴퓨터 컬러 매칭(Computer Color Matching)을 사용하여 측정하였다.In the present invention, the yellowing index and the K / S value were measured using computer color matching.
본 발명은 염색된 편물을 최종열고정(Final-Setting) 시키기 직전에 내열제가 용해된 패딩액으로 패딩처리하기 때문에 가공 편물의 내열성 및 염색성이 크게 향상되며, 그로 인해 투-웨이 편물 제조시 내열성 부족으로 빈번하게 발생되는 미염착이나 경선발생 등의 염색성 불량문제를 해결할 수 있다.In the present invention, since the padding treatment is performed with a padding liquid in which a heat-resistant agent is dissolved immediately before final-setting the dyed knitted fabric, the heat resistance and dyeability of the processed knitted fabric are greatly improved, and thus, the lack of heat resistance in the manufacture of a two-way knitted fabric Stainability problems such as unstained or meridians that occur frequently can be solved.
또한, 본 발명은 상기와 같이 내열성이 우수하기 때문에 열처리 온도를 높게 설정하여 열처리 시간을 짧게 할 수 있어서 생산성 향상에도 유리하다.In addition, since the present invention is excellent in heat resistance as described above, it is possible to shorten the heat treatment time by setting the heat treatment temperature high, which is advantageous in improving productivity.
이하, 실시예 및 비교실시예를 통하여 본 발명을 보다 구체적으로 살펴본다.Hereinafter, the present invention will be described in more detail with reference to examples and comparative examples.
