Description

개질 폴리에스테르 섬유의 감량처리방법 및 감량처리된 섬유Weight loss treatment method and modified fiber of modified polyester fiber

본 발명은 개질 폴리에스테르 섬유의 감량처리방법 및 감량처리된 섬유에 관한 것으로, 더욱 상세하게는 개질 폴리에스테르를 약알칼리인 소듐 카보네이트(Na2CO3)와 감량 촉진제인 제4급 암모늄염을 혼용하여 처리함으로써 최종 생산된 직물표면 전바닥에 걸쳐 점진적이면서 균일하게 감량시켜 피브릴(Fibril)을 고르게 형성하게 하고 염색후의 불균일성을 크게 개선시킨 개질 폴리에스테르 섬유 및 감량처러방법에 관한 것이다.The present invention relates to a weight loss treatment method of a modified polyester fiber and a weight loss treated fiber. More specifically, the modified polyester is mixed with sodium carbonate (Na 2 CO 3 ), which is a weak alkali, and a quaternary ammonium salt, which is a weight loss accelerator. The present invention relates to a modified polyester fiber and a weight loss treatment method for gradually reducing and uniformly reducing fibrils evenly over the entire bottom surface of the finished fabric by processing, and greatly improving the non-uniformity after dyeing.

일반 폴리에스테르 섬유의 유연가공시 수산화나트륨 처리법을 이용하는데 이러한 방법을 이용하여 개질 폴리에스테르 섬유를 감량처리할 경우 모노필라멘트 표면에 피브릴을 헝성하는 개질 폴리에스테르 섬유는 폴리에스테르와 비상용성인 폴리머가 섬유축 방향으로 미세하게 늘어서 있어 섬유와 폴리머 사이에 계면이 존재하여 이로 인하여 알칼리에 매우 취약하게 되며 강알칼리인 수산화나트륨에 의해 급격한 가수분해가 수반되어 감량 불균일이 발생하여 염색후에 필라멘트간 감량 편차에 의한 염색 결점을 초래하게 되는 문제점이 있다.Sodium hydroxide treatment is used for the flexible processing of general polyester fiber. When the modified polyester fiber is reduced by this method, the modified polyester fiber which fibril is formed on the surface of monofilament is a polymer fiber which is incompatible with polyester. Lined finely in the axial direction, there is an interface between the fiber and the polymer, which makes it very vulnerable to alkalis. It is accompanied by rapid hydrolysis by strong alkali sodium hydroxide, resulting in weight loss non-uniformity. There is a problem that causes defects.

한편, 일반 폴리에스테르 섬유 감량가공시 수산화나트륨의 효율적 이용을 위하여 제 4급 암모늄염을 사용하는 것(일본 특허공보 소49-30880)은 공지의 사실이나 소듐 카보네이트의 경우 그 감량속도가 늦어 학술적 연구 외에 실제 이용에는 적용되지 못하고 있다.On the other hand, the use of quaternary ammonium salts for the efficient use of sodium hydroxide in the process of weight loss of general polyester fiber (Japanese Patent Publication No. 49-30880) is a known fact, but in the case of sodium carbonate, the weight loss rate is slow, It does not apply to actual use.

따라서 본 발명은 이러한 종래 기술의 문제점을 해결하고자 하이드록사이드 이온(Hydroxide ion)의 농도가 상대적으로 매우 낮아 일반 폴리에스테르 섬유의 감량가공에 적용되지 못하는 소듐 카보네이트를 제4급 암모늄염을 촉진제로 사용하여 알칼리에 매우 민감한 피브릴상 형성성 개질 폴리에스테르 섬유의 감량에 적용하므로서 본 발명을 완성하였다.Therefore, the present invention is to solve the problems of the prior art by using sodium carbonate, which is relatively low concentration of the hydroxide ions (Hydroxide ion) is not applicable to the weight reduction processing of ordinary polyester fibers using a quaternary ammonium salt as an accelerator The present invention has been completed by applying it to the weight loss of fibrillary formable modified polyester fibers which are very sensitive to alkalis.

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

본 발명은 폴리에스테르와 비상용성이고 수평균분자량()이 10,000∼20,000인 폴리에틸렌 글리콜(PEG)이 혼합되어 있는 개질 폴리에스테르 섬유를 감량가공함에 있어 알칼리로서 소듐 카보네이트 10∼50kg/ℓ, 가수분해반응 촉진제로서 4급 암모늄 1∼30kg/ℓ로 조성된 감량액으로 처리함으로서 감량후 섬유 표면에 균일한 피브릴이 형성되어 촉감이 실크-라이크(Silk-like)하고 염색의 불균일성을 크게 개선시킨 개질 폴리에스테르 섬유의 감량처리방법에 관한 것이다.The present invention is incompatible with polyester and has a number average molecular weight ( 10 to 50 kg / l of sodium carbonate as alkali and 1 to 30 kg / l of quaternary ammonium as hydrolysis accelerator in reducing weight of modified polyester fiber mixed with polyethylene glycol (PEG) having 10,000 to 20,000) The present invention relates to a weight loss treatment method of a modified polyester fiber in which uniform fibrils are formed on the surface of the fiber after weight loss by treating with a weight loss liquid, thereby making silk-like feel and greatly improving the nonuniformity of dyeing.

본 발명에서 폴리에스테르는 특히 폴리에틸렌 테레프탈레이트를 일컫는다.Polyesters in the present invention specifically refer to polyethylene terephthalates.

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

본 발명에서 사용한 개질 폴리에스테르 섬유는 폴리에스테르 대비 1∼6중량%인 고수평균분자량의 폴리에틸렌 글리콜과 폴리에스테르가 혼합되어 폴리에스테르 내에 분산상으로 존재하는 것으로, 폴리에스테르와 비상용성인 폴리에틸렌 글리콜은 폴리에스테르에 비해 그 용융점도가 낮아 용융방사에 의하여 섬유표면에 섬유축 방향으로 늘어서 계면을 형성한다.The modified polyester fiber used in the present invention is a polyethylene glycol having a high number average molecular weight of 1 to 6% by weight of polyester and a polyester mixed and present in the dispersed phase in the polyester, and the polyethylene glycol which is incompatible with the polyester is used in the polyester. In comparison, the melt viscosity is low, and the surface is formed in the fiber axis direction by the melt spinning to form an interface.

따라서 이러한 개질 폴리에스테르 섬유를 알칼리로 처리하계 되면 섬유표면의 구조가 가장 치밀하지 못한 폴리에스테르와 폴리에틸렌 글리콜의 계면이 먼저 알칼리의 침해를 받게된다.Therefore, when the modified polyester fiber is treated with alkali, the interface between the polyester and polyethylene glycol, which has the least dense structure of the fiber surface, is first invaded by alkali.

또한 개질 폴리에스테르 섬유는 알칼리 감량속도도 일반 폴리에스테르에 비해 2.5배정도 빠르므로 일반 폴리에스테르를 감량가공할 때와 동일한 방법으로 강알칼리 처리를 할 경우 가수분해 속도가 급격히 빨라지므로 최종적으로 요구하는 감량률로 조절하기가 어렵다. 따라서 공업 생산시 감량 로트(Lot)간의 차이가 발생하며 급격한 감량에 따른 감량 불균일을 초래하게 된다. 그러므로 이러한 감량 불균일 상태를 그대로 염색하면 필라멘트간의 감량 편차에 의한 염색 결점이 발생하게 된다.In addition, the modified polyester fiber is about 2.5 times faster than the general polyester, so the strong alkali treatment speeds up rapidly in the same way as the normal polyester. Difficult to adjust Therefore, the difference between the weight loss (Lot) occurs in the industrial production, causing a loss non-uniformity due to the rapid loss. Therefore, dyeing the loss non-uniform state as it is, the dyeing defects due to the loss of variation between the filaments.

따라서 본 발명에서는 알칼리에 매우 민감한 피브릴 형성성 개질 폴러에스테르 섬유에 대하여 알칼리로서 소듐 카보네이트를 10∼50g/ℓ 사용하고 가수분해 촉진제로서 벤질 디메틸 도데실 암모늄 클로라이드(Benzyl dimethyl dodecyl ammonium chloride)등과 같은 제4급 암모늄염을 1∼30g/ℓ로 조성된 감량액으로 감량처리한다.Therefore, in the present invention, 10 to 50 g / L of sodium carbonate is used as an alkali for the fibril-forming modified polyester fiber which is very sensitive to alkali, and agents such as benzyl dimethyl dodecyl ammonium chloride as a hydrolysis accelerator. The quaternary ammonium salt is reduced in weight loss by 1 to 30 g / l.

이때 소듐 카보네이트의 양이 50g/ℓ를 초과하면 물에 대한 용해성이 떨어지며, 제4급 암모늄염의 양이 30g/ℓ를 초과하면 직물의 인열강도를 저하시키고 섬유표면에 부착되는 비율이 증가하여 감량공정 이후 불충분한 세정으로 제4급 암모늄염이 잔존할 경우 염색공정시 얼룩(Scum)발생 등의 악영향을 미치게 된다. 또한 소듐 카보네이트의 양이 10g/ℓ 미만이거나 제4급 암모늄염의 양이 1g/ℓ 미만이면 감량이 거의 일어나지 않는다.At this time, if the amount of sodium carbonate exceeds 50g / ℓ solubility in water is lowered, if the amount of quaternary ammonium salt exceeds 30g / ℓ, the tear strength of the fabric is lowered and the rate of adhesion to the fiber surface is increased to reduce If the quaternary ammonium salt remains due to insufficient cleaning after the process, it will adversely affect staining during dyeing process. Also, if the amount of sodium carbonate is less than 10 g / l or the amount of quaternary ammonium salt is less than 1 g / l, the loss hardly occurs.

그러므로 제4급 암모늄염은 가능한 최소량을 사용하되 이에 따른 감량 효율의 저하는 종전의 탱크방식이 아닌 고압식 액류 염색기를 이용하여 감량시의 온도를 100-150℃까지 올려줌으로써 보완할 수 있다.Therefore, the quaternary ammonium salt can be compensated by using the minimum amount possible, but the reduction in weight loss efficiency can be compensated by raising the temperature at the time of weight loss by using a high pressure liquid dyeing machine rather than the conventional tank method.

알칼리 가수분해에 민감한 개질 폴리에스테르의 경우 약알칼리 및 소량의 촉진제를 사용함으로써 강알칼리에 비해 미세 섬유 표면 구조에까지 균일하고 완만하게 하이드록사이드 이온을 접근시켜 주어 감량 불균 일을 방지할 수 있으며 결과적으로 염색후에 필라멘트간 감량 편차에 의한 염색 결점을 방지할 수 있다.In the case of modified polyesters sensitive to alkali hydrolysis, weak alkalis and small amounts of accelerators allow the hydroxide ions to be uniformly and gently approached to the fine fiber surface structure compared to strong alkalis, thereby preventing weight loss irregularities and consequently dyeing. Later, it is possible to prevent the dyeing defects due to the loss deviation between filaments.

이와 같은 방법으로 감량처리된 개질 폴리에스테르 섬유의 외관은 모노필라멘트 표면에 폭 0.1~2㎛, 길이 3㎛ 이상인 피브릴이 균일하게 생성되어 소프트하고 드라이한 촉감을 발현하여 실크-라이크한 효과를나타내며, 직편물 전바닥에 걸쳐 균일하게 감량되므로써 염색후 직편물내의 인접 원사간에 염착차가 없는 장점이 있다.The appearance of the modified polyester fiber reduced in this manner is uniformly produced with fibrils having a width of 0.1 to 2 µm and a length of 3 µm or more on the surface of the monofilament, expressing a soft and dry feel and exhibiting a silk-like effect. As a result, the dye is reduced evenly over the entire bottom of the knitted fabric, there is an advantage that there is no dyeing difference between adjacent yarns in the knitted fabric after dyeing.

이렇게 제조된 직편물의 최종 용도는 여성용 블라우스나 드레스 또는 점퍼용등 기존의 실크가 사용되는 의류용도로 사용됨으로써 광범위하게 고부가가치 제품이 될 수 있다.The end use of the knitted fabric thus produced can be a high value-added product in a wide range of applications, such as women's blouses, dresses or jumpers used for conventional silk.
