본 발명은 2종의 섬유형성성 폴리에스터사를 사단면에 불균일한 적층구조를 갖도록 복합 방사하고 그중 1종의 폴리에스터를 용해 제거함으로써, 직물표면에 불균일한 단면의 극세사가 배열토록하여 천연실크와 같은 부드럽고 우아한 촉감, 깊이있는 색감 및 따뜻하고 건조한 느낌들을 갖는 직물을 제조하기 위한 폴리에스터 불균일 단면 극세사의 제조방법에 관한 것이다.The present invention is a composite yarn of two fiber-forming polyester yarns having a non-uniform laminated structure on four cross-sections, and one of them is dissolved and removed, so that the microfibers of non-uniform cross-section on the fabric surface is arranged to natural silk It relates to a method for producing a polyester non-uniform cross-section microfiber for producing a fabric having a soft elegant touch, deep color and warm and dry feeling.
합성섬유는 면, 견, 양모등의 천연섬유에 비하여 섬유 한올 한올의 형태 및 물성이 균일하여 광택, 촉감, 드레이프성등이 뒤떨어지며, 종래의 이러한 문제점들을 해결하기 위하여 공지된 바와 같이 구금공의 형태를 이형화한 이형단면사의 제조방법, 또는 알Synthetic fibers are inferior in gloss, feel, and drape due to the uniform shape and physical properties of the fiber hanol compared to natural fibers such as cotton, silk, and wool. Manufacturing method or mold release section yarn mold release form
본 발명은 이를 개선하고자 하는 것으로 2종의 섬유형성성 합성폴리에스터를 각각 용융하고 혼합 방사후, 후공정에서 감량가공을 거쳐 불균일한 섬도 및 단면을 갖는 극세사를 수득하는 제조방법을 제공함을 특징으로한다.The present invention is to improve this to provide a manufacturing method for obtaining a microfiber having a non-uniform fineness and cross section after melting and mixing the two kinds of fiber-forming synthetic polyester, respectively, after mixed spinning, through a weight loss processing in a post process do.
즉, 본 발명은 2종의 섬유형성성 합성 폴리에스터를 혼합 방사함에 있어서 한 성분은 일반 폴리에스터 대비 알칼리 용출속도가 5∼15배 빠른 개질 폴리에스터(B)를 사용하고, 다른 성분으로는 일반 폴리에스터 또는 개질 폴리에스터(A)를 사용하며, 이 두 성분을 각각 용융하여 구금팩내에 설치된 정지형 혼합장치를 이용하여 적어도 12개 이That is, in the present invention, in mixing and spinning two fiber-forming synthetic polyesters, one component uses a modified polyester (B) which is 5 to 15 times faster than the general polyester in alkali dissolution rate, and the other component is general Polyester or modified polyester (A) is used, and each of these two components is melted and at least 12
본 발명에 사용되는 알칼리 용출속도가 빠른 개질폴리에스터(B)로는, 통상의 디메틸 테레프탈레이트 혹은 테레프탈릭 애시드를 사용하는 일반 폴리에스터 제조방법에, 결정성을 저하시키고 알칼리 가수분해성을 향상 시키기 위하여 디메틸술포 이소프탈레이트의 금속염을 3∼10％정도 첨가하여 제조한 공중합 폴리에스터를 지칭하며, 다른 1종의 폴리에스터(A)로는 폴리에스터를 사용하거나 결정성을 저하시켜 수축성질을 높인 이소프탈릭 에시드를 5∼10％ 첨가한 개질 폴리에스터를 사용한다.As the modified polyester (B) having a high alkali elution rate used in the present invention, in the general polyester production method using conventional dimethyl terephthalate or terephthalic acid, dimethyl dimethyl is used to reduce crystallinity and improve alkali hydrolyzability. It refers to a copolyester prepared by adding about 3 to 10% of a metal salt of sulfo isophthalate. Another type of polyester (A) is an isophthalic acid which uses polyester or decreases crystallinity to increase shrinkage. Modified polyester added with 5-10% is used.
이하 본 발명을 구형하기 위한 정지형 혼합기를 포함하는 구금장치를 도면을 참조하여 설명한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A detention apparatus including a stationary mixer for sphering the present invention will now be described with reference to the drawings.
제1도는 본 발명에 사용되는 구금장치의 개략도로써, 각각 압출기로 부터 용융 압출된 일반 폴리에스터 혹은 개질 폴리에스터(A)와 알칼리 용출 속도가 빠른 개질 폴리에스터(B)가 구금팩(1)으로 주입, 구금필터(2)에서 여과되며 분배판(3)을 경유, 혼합판(4)의 중앙부에 도달하고, 혼합판(4)의 정지형 혼합기(5)에서 불균일하게 혼합되어 양 폴리머가 8∼15％층의 복합층류를 이루게 형성한다. 이렇게 형성된 복합 층류는 정지형 혼합기(5)의 출구부(6)에서 서서히 동심원상으로 퍼지며 방사구금(7)에 설치된 12개 이상의 이형구금공(8)을 통하여 토출성형 방사된다. 본 발명의 정지형1 is a schematic view of the detention apparatus used in the present invention, in which the ordinary polyester or modified polyester (A) melt-extruded from the extruder and the modified polyester (B) having a high alkali elution rate into the detention pack (1), respectively. It is injected and injected into the detention filter (2), and reaches the center of the mixing plate (4) via the distribution plate (3), and is mixed unevenly in the stationary mixer (5) of the mixing plate (4). It is formed to form a composite laminar flow of 15% layer. The composite laminar flow thus formed is gradually spread concentrically from the outlet portion 6 of the stationary mixer 5 and discharged through the 12 or more release mold holes 8 provided in the spinneret 7. Stationary type of the present invention
또한 방사구금(7)에 있어서, 구금공(8)의 수는 12개 이상이 되어야 하며 그 미만이 되면 두 폴리머가 방사공을 통하기 전에 블렌드(blend) 상태가 되어 방사 안정성이 현저하게 저하된다. 방사공의 형상은 사의 외관, 광택, 불균일한 단면등을 고려할때 원형보다는 삼각, 편평 또는 U자형 단면이 적당하며, 두 폴리머 간의 접합 비율은 방사 안정성, 감량후의 촉감등을 고려하여 결정되어야 하지만 해당비율은 폴리에스터(B)의 중량비가 30∼50중량％가 적당하다. 폴리에스터(B)의 중량비가 30중량％미만일 경우에는 감량 가공시 분할이 안되는 경우가 발생하며 50중량％이상일 경우에는 촉감 및 반발력, 탄성등이 현저하게 저하된다. 이렇게 하여 방사된 원사는 용도 및 목적에 따라 단독으로 또는 가연이나 혼섬등을 하여 포면을 제직한다. 포면은 특별한 한계를 두지 않으나 해당 원사를 표면부에 위치시켜야만 하므로 경사 또는 프론트사로 이용하는 것이 좋다. 감량가공은 일반적인 폴리에스터의 직물 감량조건을 따르며 폴리에스터(B)의 중량비를 10％ 초과하는 비율의 감량율을 갖도록 한다. 감량율이 그보다 미만이면 원사내에 폴리에스터(B)가 잔존하여 염색성 저하 및 분할성이 저하되며 그 이상일 경우 경제성이 적어지게 된다. 이상과 같은 방법으로 수득한 포면의 표면은 0.1∼1데니어의 불규칙한In addition, in the spinneret 7, the number of the prisoners 8 should be 12 or more, and if it is less than that, the two polymers will be in a blended state before passing through the spinneret, and the spinning stability will be significantly reduced. The shape of the spinneret is more appropriate than triangular, flat or U-shaped cross section, considering the appearance, gloss, and non-uniform cross section, and the bonding ratio between the two polymers should be determined in consideration of spinning stability and touch after weight loss. As for ratio, 30-50 weight% of the weight ratio of polyester (B) is suitable. When the weight ratio of the polyester (B) is less than 30% by weight, it is not possible to divide during weight loss processing, and when it is 50% by weight or more, the touch, resilience, elasticity, etc. are remarkably decreased. The yarn spun in this way is weaved with cotton alone or with combustible or mixed fibers depending on the purpose and purpose. There is no particular limitation on the surface, but it is better to use it as a warp or front yarn because the yarn must be placed on the surface. The weight reduction process follows the general weight loss condition of polyester and has a weight loss ratio of more than 10% of the weight ratio of polyester (B). If the reduction rate is less than that, the polyester (B) remains in the yarn, and the dyeing property is lowered and the partitioning property is lowered. The surface of the surface obtained by the method described above is 0.1-1 denier irregular
즉, 본 발명에 의하여 제조된 폴리에스터 복합사는 감량후 불균일한 섬도 및 단면 형태를 갖는 극세섬유로 분리되어 그 일부가 직물표면에 돌출함에 의하여 천연실크와 같은 부드럽고 우아한 촉감, 깊이 있는 색조 및 따뜻하고 건조한 감을 갖는 고급직물의 제조에 이용된다.That is, the polyester composite yarn produced according to the present invention is separated into microfibers having non-uniform fineness and cross-sectional shape after weight loss, and a part thereof protrudes from the surface of the fabric, so that a soft and elegant feel like natural silk, deep color tone, and warm and dry It is used in the manufacture of high quality fabrics with a sense.
