번 아웃 가공방법 {Burn-out Finishing of Polyamide}Burn-out Finishing Method {Burn-out Finishing of Polyamide}

본 발명은 번-아웃 가공방법에 관한 것으로, 상세하게는 폴리아미드 및 폴리우레탄과 폴리에스테르 및 아크릴 교직물에서 폴리아미드 및 폴리우레탄 섬유를 선택적으로 분해 제거하면서 남아있는 폴리에스테르 및 아크릴 섬유에 황변이 발생하지 않도록 하는 폴리아미드 및 폴리우레탄의 번 아웃 가공방법에 관한 것이다. The present invention relates to a burn-out processing method, in particular, yellowing occurs in the remaining polyester and acrylic fibers while selectively decomposing and removing the polyamide and polyurethane fibers in polyamide and polyurethane and polyester and acrylic fabrics. The present invention relates to a burnout processing method of polyamide and polyurethane, which is to be avoided.

일반적으로 폴리아미드나 폴리에스테르의 경우 고온, 산성조건에서 안정하지 못하지만 특정의 산성 물질 황산수소나트륨에서는 그 두 섬유간의 내구성 차이가 크게 나타나 폴리아미드를 선택적으로 제거할 수 있는 방법이 일반적으로 알려져 있다. 그러나 작업 후 폴리에스테르에 황변내지 타르화현상이 발생하여 정상적인 섬유제품화하기 어렵고 또한 그로 인한 두 합성섬유 교직물의 번 아웃 제품의 시장도 형성되어 있지 못하다. 다른 폴리아미드의 번 아웃 약제로 개미산을 사용할 수 있으나 원액에 가까운 고농도의 개미산을 사용해야 하고 열처리 시 휘발성이 있어 안전성에 심각한 문제점이 발생하고 또한 페놀로서 폴리아미드를 번 아웃시킬 수 있으나 폐수에 의한 환경오염 때문에 사용 불가능하겠다.In general, polyamide or polyester is not stable at high temperature and acidic conditions, but a specific acidic substance, sodium hydrogen sulfate, shows a large difference in durability between the two fibers, and a method of selectively removing polyamide is generally known. However, the yellowing or tarting phenomenon occurs in polyester after the operation, which makes it difficult to produce a normal fiber product, and therefore, the market for burnout products of two synthetic fiber interwoven fabrics is not formed. Although formic acid can be used as a burnout agent of other polyamides, high concentrations of formic acid close to the stock solution should be used, and there is a serious problem in safety due to volatility during heat treatment, and polyamide can be burned out as phenol, but environmental pollution by wastewater It will not be available.

따라서, 본 발명의 목적은 폴리아미드 또는 그와 유사한 물성의 폴리우레탄과 폴리에스테르 또는 아크릴과의 교직물에서 폴리아미드 또는 폴리우레탄의 번 아웃 가공시 작업성이 안전하고 환경에 피해주지 않으면서 남아있는 폴리에스테르나 아크릴에 황변을 유발하지 않는 산성 물질과 산의 효과를 비교적 저온에서 극대화할 수 있는 촉매를 제공하는 것이다. Accordingly, it is an object of the present invention to ensure that workability is safe during burnout processing of polyamides or polyurethanes in crosslinks of polyamides or similar properties of polyurethanes with polyesters or acrylics, and that the remaining poly It is to provide a catalyst that can maximize the effect of acid and acid that does not cause yellowing in the ester or acrylic at a relatively low temperature.

본 발명의 다른 목적은 상기 촉매를 사용하여 폴리아미드 또는 그와 유사한 물성의 폴리우레탄과 폴리에스테르 또는 아크릴과의 교직물에서 폴리아미드 또는 폴리우레탄의 번 아웃 가공 방법을 제공하는 것이다. It is a further object of the present invention to provide a process for the burnout of polyamides or polyurethanes in a blend of polyamides or similar physical polyurethanes with polyesters or acrylics using the catalyst.

상기 본 발명의 목적은 기존의 황산수소나트륨과 동시에 촉매로서 아질산이나 질산 또는 그들의 금속염, 또는 유기 설폰산을 사용하는 것에 의해 달성된다. The object of the present invention is It is achieved by using nitrous acid, nitric acid or their metal salts, or organic sulfonic acid as a catalyst simultaneously with existing sodium hydrogen sulfate.

또한 상기 본 발명의 다른 목적은 황산수소나트륨과 동시에 촉매로서 아질산이나 질산 또는 그들의 금속염, 또는 유기 설폰산을 사용하여 100℃~140℃에서 열처리하는 것으로 구성되는 폴리아미드 또는 폴리우레탄 섬유의 번 아웃 가공방법에 의해 달성된다. In addition, another object of the present invention is to burn out polyamide or polyurethane fiber which is composed of heat treatment at 100 ° C. to 140 ° C. using nitrous acid, nitric acid or their metal salt, or organic sulfonic acid as a catalyst simultaneously with sodium hydrogen sulfate. Is achieved by the method.

번 아웃 가공은 직물을 독특하게 표현할 수 있는 특수가공 방법이다.Burnout processing is a special processing method that uniquely expresses the fabric.

주로 직물을 구성하는 두 종류의 실의 화학적 물성 차이가 큰 셀루로스/폴리에스테르 교직물에서는 셀루로스를 쉽게 제거할 수 있어 오래전부터 많이 사용되어 오고 있다.Cellulose / polyester fabrics, which have large chemical differences between the two types of yarns, are mainly used for a long time since cellulose can be easily removed.

그러나 두 종의 실이 화학적 물성차이가 크지 않는 폴리아미드나 폴리에스테르 등의 합성사로 이루어진 경우 어느 하나의 실을 선택적으로 제거하기가 매우 까다롭다.However, it is very difficult to selectively remove either yarn when the two yarns are made of synthetic yarn such as polyamide or polyester, which does not have a large chemical difference.

특히 폴리아미드/폴리에스테르 교직물의 경우 기존의 황산수소나트륨(NaHSO4)를 사용하여 170℃에서 열처리하면 폴리에스테르에 매우 심한 황변이 발생하여 상품가치가 없어지게 되며 표백하는 방법 또한 쉽지가 않다.In particular, polyamide / polyester blends are heat treated at 170 ° C. using conventional sodium hydrogen sulphate (NaHSO 4 ), resulting in very severe yellowing of the polyester, resulting in a loss of commodity value and a bleaching process.

본 발명자는 기존의 황산수소나트륨과 동시에 촉매로서 아질산이나 질산 및 그들의 금속염, MNO3, 혹은 MNO2를 사용하면 기존의 170℃ 열처리보다 낮은 130℃~140℃에서 폴리에스테르에 황변을 발생시키지 않고 깨끗하게 번 아웃 제품을 만들 수 가 있었다. 금속 M은 Na, k, Zn, Fe, Al 등의 것이 사용될 수 있으나 경제적으로 Na염을 사용하는 것이 바람직하며 그 사용량은 전체 호료중에 2~10%의 중량비로 사용하는 것이 바람직하다. 2%이하에서는 폴리에스테르나 아크릴 섬유에 황변이 발생될 수도 있다. 또한 본 발명자는 무기산이나 그들의 금속염 대신 유기산으로 유기 설폰산을 사용할 경우 열처리 온도가 휠씬 낮은 100℃에서도 폴리에스테르나 아크릴에 황변을 발생시키지 않고 깨끗하게 번 아웃 제품을 만들 수 가 있었다. 이것은 폴리아미드나 폴리우레탄이 소수성섬유이면서 적당한 친수기를 가지고 있어서 무기산수용액보다 유기산의 섬유 흡착력이 우수하기 때문일 것으로 추측된다. 유기산은 R-SO3H 및 (R)n

Figure 112005024670165-pat00001
SO3H (R은 C1~C20의 알칼기이며 n는 1~3)이다. The present inventors use nitrous acid, nitric acid and their metal salts, MNO 3 , or MNO 2 as a catalyst at the same time as the existing sodium hydrogen sulfate to clean yellow without generating yellowing of the polyester at 130 ° C. to 140 ° C., which is lower than the existing 170 ° C. heat treatment. Could make a burnout product. The metal M may be Na, k, Zn, Fe, Al, etc., but economically, it is preferable to use Na salt, and the amount of the metal M is preferably used in a weight ratio of 2 to 10%. Below 2%, yellowing may occur in polyester or acrylic fibers. In addition, the present inventors were able to make a burnout product cleanly without generating yellowing in polyester or acrylic even at 100 ° C., when the organic sulfonic acid was used as an organic acid instead of an inorganic acid or a metal salt thereof, even at a low heat treatment temperature. This is presumably because polyamide or polyurethane is a hydrophobic fiber and has an appropriate hydrophilic group, and thus the fiber adsorption power of the organic acid is superior to the inorganic acid aqueous solution. Organic acids are R-SO 3 H and (R) n
Figure 112005024670165-pat00001
SO 3 H (R is an alkyl group of C 1 ~ C 20 and n is 1-3).

그 사용하는 양은 전체 호료중에 2~30%정도가 적당하다. 만일 호료중에 분산염료로서 폴리에스테르 및 아크릴 착색을 동시에 행하고자하면 위에 언급된 유기 설폰산을 약 2%~7%정도 사용 후 다른 유기산으로 수산이나 구연산, 글루콘산등을 전체 호료중 각각 독립적 및 서로 혼합하여 5~20%정도를 동시에 사용하는 것이 바람직하다.The amount used is about 2 to 30% of the total flavor. If you want to simultaneously color polyester and acrylic as a disperse dye in the paint, use about 2% to 7% of the organic sulfonic acid mentioned above and then use the other organic acids as independent organic acids. It is preferable to mix and use about 5-20% simultaneously.
