Description

폴리에스테르 섬유의 감량처리방법Weight loss treatment method of polyester fiber

본 발명은 폴리에스테르 섬유의 감량처리방법에 관한 것으로, 더욱 상세하게는 일반 폴리에스테르 섬유 및 감량공정 중 수산화나트륨에 대하여 매우 민감한 성분을 섬유내에 함유하는 개질 폴리에스테르 섬유의 감량가공시 탱크(Tank)감량식보다 효율적으로 감량할 수 있도록 유기 술폰산 금속염을 수산화나트륨 수용액 속에 첨가하여 감량을 촉진키키고 직물표면 전바닥에 걸쳐 더욱 균일하게 감량시킴으로써 감량편차를 최대한 줄여 염색 후의 불균일성을 크게 개선시킨 폴리에스테르 섬유의 감량처리방법에 관한 것이다.The present invention relates to a weight loss treatment method of polyester fibers, and more particularly, to a tank for weight loss processing of modified polyester fibers containing a very sensitive component to the general polyester fiber and sodium hydroxide during the weight loss process. Polyester fiber with organic sulfonic acid metal salt added to aqueous solution of sodium hydroxide to reduce the weight loss more efficiently. It relates to a weight loss treatment method.

종래 기술에 의하여 수산화나트륨 수용액을 단독으로 처리시 처리 농도, 온도, 시간이 증가하면 감량률이 증가하는 것은 공지의 사실이며, 가수분해효율을 높이기 위하여 가수분해 촉진제로 아민류 및 제4급 아민염류를 사용(일본 특허공보 소49-30880)할 수 있으나, 적용된 직물의 인열강도가 급격히 저하되는 문제점이 있다. 또한, 폴리에스테르 섬유 표면의 매끄러움을 개량한 피브릴(Fibril)상 개질 폴리에스테르 섬유의 제조방법으로서 폴리에스테르와 폴리에스테르에 비상용성 폴리머를 혼합하여 용융방사하는 방법(일본 특개소 55-16906)이 제안되고 있으나 이러한 피브릴상 섬유로 구성된 직물은 일반 수산화나트륨으로 처리할 경우 섬유표면상에 피브릴들이 불규칙적으로 나타나 염색 후 최종 직물을 검사할 때 길이방향의 불규칙적인 결점이 발생하는 문제점이 있다.It is well known that the loss ratio increases when the treatment concentration, temperature, and time are increased by treating the sodium hydroxide aqueous solution by the prior art alone, and amines and quaternary amine salts are used as hydrolysis accelerators to increase the hydrolysis efficiency. Although it can be used (Japanese Patent Publication No. 49-30880), there is a problem that the tear strength of the applied fabric is sharply lowered. In addition, as a method for producing fibrillated modified polyester fibers having improved smoothness of the surface of polyester fibers, a method of melt spinning by mixing incompatible polymers with polyesters and polyesters (Japanese Patent Laid-Open No. 55-16906) However, the fabric composed of fibrillated fibers has a problem that irregularities in the longitudinal direction occur when inspecting the final fabric after dyeing because fibrils appear irregularly on the fiber surface when treated with general sodium hydroxide.

또한 탱크식 설비를 이용하여 감량할 때 감량효율을 높여주기 위하여 단순히 수산화나트륨의 농도를 높여주는 것은 작업상의 위험요소가 따르며 더우기 제4급 아민 염류와 같은 가수분해 촉진제를 사용하면 감량속도의 제어가 어려워 일반 폴리에스테르 섬유는 물론 감량에 민감하여 더욱 정밀한 감량률 제어를 필요로하는 개질 폴리에스테르 섬유의 적용에 한계가 있다.In addition, simply increasing the concentration of sodium hydroxide in order to increase the weight loss efficiency when using a tank-type equipment is a risk of work, and moreover, the use of hydrolysis accelerators such as quaternary amine salts, There are limitations to the application of modified polyester fibers, which are difficult and therefore sensitive to weight loss as well as require more precise weight loss control.

이에 본 발명자들은 종래 기술의 이러한 문제점을 해결하기 위하여 감량가공시 유기 술폰산 금속염을 사용하여 수산화나트륨의 농도 변화없이 감량속도를 조절하고 감량을 더욱 균일하게 하여 알칼리에 매우 민감한 피브릴상 개질 폴리에스테르 섬유를 감량처리할 때 최종 직물상의 염색결점이 없는 섬유를 제조하는 폴리에스테르 섬유의 감량처리방법을 제공하는데 그 목적이 있다.In order to solve this problem of the prior art, the present inventors use organic sulfonic acid metal salt during weight loss processing to control the weight loss rate without changing the concentration of sodium hydroxide and to make the weight loss more uniform, thereby making the fibrillated modified polyester fiber very sensitive to alkali. It is an object of the present invention to provide a weight loss treatment method of a polyester fiber for producing a fiber without dyed defects on the final fabric when the weight loss treatment.

이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명은 다음 식(1)로 표시되는 유기 술폰산 금속염을 감량액인 수산화나트륨 수용액속에 소량 첨가함으로써 일반 폴리에스테르 섬유에 있어서는 수산화나트륨을 더욱 저농도로 사용할 수 있고 감량에 민감한 개질 폴리에스테르 섬유에 있어서는 수산화나트륨 농도간의 급격한 감량률차를 더욱 정밀하게 조절하여 염색 불균일을 개선시키는 폴리에스테르 섬유의 감량처리방법에 관한 것이다.According to the present invention, by adding a small amount of the organic sulfonic acid metal salt represented by the following formula (1) into an aqueous solution of sodium hydroxide, which is a weight loss solution, sodium hydroxide can be used at a lower concentration in general polyester fibers, and hydroxylated in modified polyester fibers sensitive to weight loss. The present invention relates to a weight loss treatment method of a polyester fiber that more precisely controls the difference in weight loss between sodium concentrations to improve dyeing unevenness.

상기 식에서 R은 탄소수 7∼25인 알킬기 또는 탄소수 7∼40인 아릴기 M은 알칼리 금속Wherein R is an alkyl group having 7 to 25 carbon atoms or an aryl group M having 7 to 40 carbon atoms is an alkali metal

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명의 일반 폴리에스테르 섬유는 수산화나트륨 수용액중에 식(1)의 유기 술폰산 금속염을 5-50g/ℓ함유하는 감량액 중에서 처리하여 얻어진 감량률이 10% 이상을 만족한다.The general polyester fiber of this invention satisfy | fills 10% or more of the reduction rate obtained by processing in the weight loss liquid which contains the organic sulfonic acid metal salt of Formula (1) 5-50 g / L in aqueous sodium hydroxide solution.

또한 피브릴상 개질 폴리에스테르 섬유는 일반 폴리에스테르 섬유와 동일한 감량액 중에서 처리하여 얻어진 모노핀라멘트상에 균일한 피브릴을 형성하고 그 섬유로 구성된 직물을 불균일 감량하였을 때 염색 결점이 없는 섬유로 한다.In addition, the fibrillated modified polyester fiber forms a uniform fibril on the monopinament obtained by treatment in the same weight loss solution as the general polyester fiber, and when the woven fabric composed of the fiber is non-uniformly reduced, the fiber has no dyeing defect. .

여기서 염색 결점이 없는 섬유는 상기 개질 폴리에스테르 원사 14본씩을 편물로 제직한 후 본 발명의 감량액으로 감량처리하고 염색한 제편물을 인접 원사간 염착차로 판정했을 때 인접 원사간에 염착차가 없는 균일한 섬유를 말한다.Here, the fibers without dyeing defects are treated with 14 modified polyester yarns by knitting, and then reduced by the loss solution of the present invention, and when the dyed knitted fabric is judged as a dyeing difference between adjacent yarns, there is no dyeing difference between adjacent yarns. Refers to uniform fibers.

감량액중 유기 술폰산 금속염의 첨가에 의한 감량촉진효과는 폴리에스테르 섬유 자체의 소수성과 수산화나트륨 수용액간의 계면활성을 가지며 기존의 제4급 아민 염류와 같은 촉진제와 비교하여 그 촉진속도가 완만하므로 더욱 안정하게 작용한다.The weight loss effect by the addition of the organic sulfonic acid metal salt in the weight loss liquid has a surface activity between the hydrophobicity of the polyester fiber itself and an aqueous sodium hydroxide solution, and is more stable since its acceleration rate is slower than that of the conventional quaternary amine salts. It works.

한편, 고분자량의 폴리에틸렌글리콜(PEG)과 블랜딩되어 있고 섬유 표면에 세밀한 구조를 갖는 개질 폴리에스테르 섬유는 수산화나트륨 수용액 단독으로 처리하면 미세섬유 표면구조에 대하여 감량 불균일을 초래하는 반면 유기 술폰산 금속염과 함께 동시에 처리하면 미세섬유 표면구조에까지 골고루 알칼리액을 접근시켜 주어 감량 불균일을 막아줄 수 있으며 결과적으로 염색 후에 필라멘트간의 감량편차에 의한 염색 결점을막을 수 있게 된다.On the other hand, modified polyester fibers blended with high molecular weight polyethylene glycol (PEG) and having a fine structure on the fiber surface, when treated with aqueous sodium hydroxide solution alone, lead to weight loss non-uniformity with respect to the surface structure of microfibers, together with organic sulfonic acid metal salts. At the same time, evenly distributed alkaline liquids can be evenly distributed to the microfiber surface structure to prevent weight loss irregularities. As a result, dyeing defects due to weight loss deviations between filaments can be prevented after dyeing.

수산화나트륨 수용액 단독 처리방법과 비교할 때 유기 술폰산 금속염을 감량 촉진제로 사용하는 방법은감량 촉진제의 역할에 의하여 감량처리효율이 중대되고, 수산화나트륨 농도의 변화에 따른 감량률의 변화폭에 대해 보다 정밀한 감량률 관리가 가능하다. 또한, 감량에 민감한 섬유로 구성된 직편물에 대해서는 감량 균일성을 부여함으로써 염색성이 균일한 직편물의 안정된 공급을 할 수 있다.The method of using organic sulfonic acid metal salt as a weight loss accelerator is significant compared to the treatment method of sodium hydroxide solution alone, and the weight loss efficiency is significant due to the role of weight loss accelerator, and the weight loss rate is more precise with respect to the change in weight loss rate according to the change of sodium hydroxide concentration. Management is possible. In addition, with respect to the knitted fabric composed of fibers sensitive to weight loss, by providing weight uniformity, it is possible to provide a stable supply of the knitted fabric having a uniform dyeing property.

따라서 본 발명은 일반 폴리에스테르 섬유의 경우에는 감량효율의 극대화를 부여하고, 피브릴 형성성 개질 폴리에스테르 섬유의 경우에는 무기입자를 과량 함유하거나 공중합되어 있어서 감량에 민감하여 감량 편차로 인한 공정사고가 발생할 수 있으므로 감량시 균일한 피브릴들 형성하여 감량 균일성을 부여하기 위하여 이용된다.Therefore, the present invention provides maximization of weight loss efficiency in general polyester fiber, and in the case of fibril-forming modified polyester fiber, excessive amount of inorganic particles or copolymerization is sensitive to weight loss, resulting in process accidents due to weight loss variation. As it may occur, it is used to form uniform fibrils during weight loss to impart weight loss uniformity.

이하, 본 발명을 실시예 및 비교예를 통하여 더욱 구체적으로 설명하겠는 바, 본 발명이 실시예로 인하여 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited to the Examples.
