Description
본 발명은 염색 견뢰도가 우수한 폴리아미드/폴리에스테르 분할극세사 및 이를 이용한 원단 제조방법에 관한 것으로 분할극세사를 형성하는 폴리에스테르의 염색성을 개선하여 강도 및 염색 견뢰도가 향상된 폴리아미드/폴리에스테르 분할극세사 및 이를 이용한 원단 제조방법에 관한 것이다.The present invention relates to a polyamide / polyester segmented micro-yarn having excellent dye fastness, and a method of fabricating the same using the same. The present invention relates to a polyamide / polyester segmented micro-yarn having improved strength and dye fastness by improving the dyeability of a polyester forming split micro- The present invention relates to a method of manufacturing a fabric.
지난 수십년간 화섬 교직물 시장의 가장 큰 인기 품목으로 각광 받고 있는 폴리아미드/폴리에스테르 분할극세사의 판매 및 생산 수량이 최근 들어 급감하고 있다. The sales and production volumes of polyamide / polyester microfibers, which have been favored as the most popular items in the synthetic textile market for decades, have been declining in recent years.
상기 분할극세사의 용도로는 의류용으로는 트렌치코트, 쟈켓, 바짓감 널리 이용되며, 산업용 및 생활용으로는 반도체 클리너, 와이핑 클로스, 소파 및 잡화류에 널리 사용되었지만, 수량이 줄어 들고 있는 게 사실이다.As for the use of the microfibers, the trench coat, the jacket, and the baguette are widely used for the garment, and the semiconductor and the life-saving are widely used for the semiconductor cleaner, the wiping cloth, the sofa and the general merchandise. .
상기 분할극세사의 수요가 크게 감소하는 이유는 감성적인 촉감적인 면에서는 탁월하나, 색상이 강조되는 염색 부분에서 견뢰도가 매우 불량하기 때문이다.The reason for the decrease in the demand of the micro-split microfiber is remarkable in the emotional tactile sense, but in the dyeing portion where the color is emphasized, the fastness is very poor.
일반적인 합섬 직물의 견뢰도의 경우 4~5급의 우수한 견뢰도를 요구하지만, 분할극세사를 사용할 경우 2~3급 정도의 불량한 견뢰도를 나타낸다. In general, the fastness of synthetic fabric requires an excellent fastness of 4 to 5 grade, but a poor fastness of 2 to 3 grade when using split microfiber.
이러한 이유는 분할극세사를 염색하기 위해 분산염료를 사용시에 폴리아미드가 분산염료에 완벽한 염착이 형성되지 못해 오염이 발생하고 세탁이나 일광에 노출시 오염이 되어 있던 염료 입자들이 빠져나와 견뢰도를 저하시키게 된다.This is because when the disperse dye is used to dye the split microfiber yarn, the polyamide does not form a perfect dyeing on the disperse dye, so that the dye is contaminated and when the dye is exposed to washing or sunlight, the contaminated dye particles are pulled out and the fastness is lowered .
이러한 문제를 해결하기 위해 분산염료와 산성염료의 2가지를 사용하여 이욕으로하는 염색 방법도 사용되고 있으나 생산 원가가 비싸지고, 생산량이 급격히 떨어지는 단점으로 상용화되지 못하고 있는 실정이다. In order to solve this problem, a dyeing method using a disperse dye and an acid dye is also used, but it has not been commercialized as a disadvantage that the production cost becomes high and the production amount drops sharply.
또한, 상기 분할극세사는 폴리아미드와 폴리에스테르를 분할시키기 위해 수산화나트륨 수용액에 침지시켜 폴리에스테르의 용융으로 폴리아미드와 폴리에스테르를 분리시키고 있으나, 수산화나트륨 수용액에 의해 일부분이 용융된 폴리에스테르는 물성이 저하되어 원단으로 형성시에 강도가 저하되는 문제점이 있었다.In addition, the divided microfiber yarn is made by immersing the polyamide and the polyester in an aqueous solution of sodium hydroxide to divide the polyamide and the polyester to separate the polyamide and the polyester by melting the polyester. However, the polyester in which a part is melted by the aqueous solution of sodium hydroxide, There is a problem that strength is lowered when it is formed into a fabric.
대한민국 공개특허 제2007-0056222호에서는 폴리아미드 한 성분에, 또는 폴리아미드와 폴리에스테르 두 성분 모두에 안료 또는 염료가 함유된 액상 형태의 착색제를 첨가시킨 원착 분할형 복합섬유로 원사 상태에서 컬러가 착색되기 때문에 견뢰도가 우수하나 생산 원가가 높고 색상이 한정되어 실용성이 떨어지는 문제가 있다.Korean Patent Publication No. 2007-0056222 discloses a splittable splittable conjugate fiber prepared by adding a liquid coloring agent containing a pigment or dye to both one component of a polyamide and either of a polyamide and a polyester, But it has a problem that the color fastness is high, the production cost is high, the color is limited, and the practicality is low.
대한민국 공개특허 제2006-0078212호는 폴리에스테르/폴리아미드 분할형 복합사 및 이의 제조방법에 관한 것으로 사이클로 헥산 1,4-디메탄올을 전체 중합물의 글리콜 성분에 대해 1 내지 10 몰% 중합시킨 심색성의 폴리에스테르 중합물과 폴리아미드 중합물로 형성되는 폴리에스테르/폴리아미드 분할형 복합사로 심색성을 향상된 효과가 있으나 견뢰도는 오히려 더 떨어지는 문제가 있다.Korean Patent Laid-Open Publication No. 2006-0078212 relates to a polyester / polyamide splittable conjugate yarn and a process for producing the same, and relates to a polyester / polyamide splittable conjugate yarn and a process for producing the same, wherein the cyclohexane 1,4-dimethanol is polymerized in an amount of 1 to 10 mol% The polyester / polyamide splitting composite yarn formed of a polyester polymer and a polyamide polymer has an improved carding property but has a problem of lowering the fastness.
따라서, 폴리아미드/폴리에스테르 분할극세사의 염색 견뢰도가 우수하면서도 물성이 우수한 분할극세사가 요구되고 있는 실정이다.Therefore, there is a demand for a microfibers which have excellent dye fastness and excellent physical properties of polyamide / polyester segmented microspheres.

◈ 실시예와 비교예의 염색 견뢰도 및 인열강도 평가◈ Evaluation of dye fastness and tear strength of the examples and comparative examples
상기에서 제조된 실시예 1,2와 비교예 1 내지 3의 원단에 대한 염색 견뢰도와 인열강도를 측정하여 표 1에 나타내었다.The color fastness and tearing strength of the fabric prepared in Examples 1 and 2 and Comparative Examples 1 to 3 were measured and shown in Table 1.

세탁견뢰도는 KSK 0430, 일광견뢰도는 KSK 0704, 마찰견뢰도는 KSK 0650으로 측정하였다.Wash fastness was measured with KSK 0430, daylight fastness with KSK 0704, and fastness to rubbing with KSK 0650.
2. 원단의 인열 강도는 KSK 0536으로 측정하였다.2. Tear strength of fabric was measured by KSK 0536.
표 1에서와 같이 본 발명에 따른 염색 견뢰도가 우수한 폴리아미드/폴리에스테르 분할극세사를 함유하는 원단인 실시예 1,2는 세탁견뢰도, 일광견뢰도, 마찰견뢰도가 모두 4~5급으로 매우 우수한 것으로 염색 견뢰도가 매우 우수한 것을 알 수 있으며, 인열강도 역시 40kg 수준으로 높은 수치를 나타내었다.As shown in Table 1, Examples 1 and 2, which are fabrics containing polyamide / polyester microparticles with excellent dye fastness according to the present invention, exhibit excellent washing fastness, light fastness, and fastness to rubbing of 4 to 5, It was found that the fastness was very good and the tear strength was also 40kg.
