Description
본 발명은 셀룰로오스 디아세테이트 섬유와 폴리에스테르 태세사(Thick & Thin Yarn)를 함께 유체 교락 처리한 후 셀룰로오스 디아세테이트 섬유의 레이온화 가공 공정에서 발생하는 수축율과 폴리에스테르 태세사의 이수축 특성을 이용하여, 직물상태에서 우수한 부품성, 샤리감, 흡습성, 드레이프성, 신축성을 가지며 자연스러운 외관과 뛰어난 톤(Tone)효과가 발현되는 폴리에스테르 태세사/셀룰로오스 이수축 혼섬 직편물의 제조방법에 관한 것이다.The present invention utilizes the shrinkage rate and bishrinkage characteristics of the polyester posture yarn generated during the rayonization process of the cellulose diacetate fibers after fluid entanglement of the cellulose diacetate fibers and polyester thick yarn (Thick & Thin Yarn) together, The present invention relates to a method for producing a polyester tether / cellulose bispun woven fabric having excellent parts properties, shariness, hygroscopicity, drape, and elasticity in a fabric state and having a natural appearance and excellent tone effect.
일반적으로 아세테이트사는 목재의 펄프, 즉 셀룰로오스 성분으로부터 만들어지는 섬유로서 그 자체가 천연섬유인 실크 또는 재생섬유인 레이온과 매우 유사한 직물 특성을 갖고 있다.In general, acetate yarns are made from wood pulp, a cellulosic component, and have fabric properties very similar to rayon, which is itself silk or recycled fibers.
그러나 고유의 특성인 화려한 광택, 우수한 드레이프성, 드라이한 질감 등천연섬유에 버금가는 많은 장점을 가지고 있음에도 불구하고 강도가 약하다는 단점 때문에 아세테이트 사 단독으로는 외의(外衣)로서는 사용하지 못하고 주로 양복의 안감으로만 사용할 수 있다는 등 용도 전개에 많은 제약을 받고 있다.However, due to its weak strength, despite its many advantages over natural fibers, such as its brilliant luster, excellent drape, and dry texture, acetate is not used alone. There are many limitations in the development of the application, such as the use of only lining.
이러한 용도 제약을 해결하기 위해서 폴리에스테르 섬유와 같이 강도가 큰 타 소재와의 복합사를 만들어 사용하는 것이 일반적인 추세이다.In order to solve such application constraints, it is a general trend to make composite yarns with other materials having high strength such as polyester fibers.
폴리에스테르 태세사(Thick & Thin)의 경우 미연신사등을 유리 전이 온도 부근에서 자연 연신비 부근에서 연신함으로써 미연신사의 물성을 가지는 태(Thick)부와 연신사의 물성을 가지는 세(Thin)부를 구성하는 것으로 직물상에서 샤리감과 드라이감을 가지며, 염색성의 차이로 인하여 우수한 톤(Tone)효과가 발현된다.In the case of polyester thick yarn (Thick & Thin), by drawing the non-drawn yarn, such as near the glass transition temperature near the natural draw ratio to form the thick portion having the properties of the undrawn yarn and the thin portion having the properties of the drawn yarn It has a sense of shari and dry on the fabric, and excellent tone effect is expressed due to the difference in dyeability.
종래, 위와 같은 폴리에스테르 태세사와 일반적인 레이온 섬유를 사용하여 복합사를 제조하는 경우 우수한 톤(Tone)효과를 가지나 수축율 차이가 적어 충분한 이수축 효과를 가지지 못하는 결점을 가지고 있었다.Conventionally, when the composite yarn is manufactured using the polyester poise yarn and the general rayon fiber as described above, the composite yarn has an excellent tone effect, but the shrinkage difference does not have enough shrinkage effect.
따라서 본 발명은 상기한 바와 같은 선행기술의 문제점이 없이 폴리에스테르 태세사(Thick and Thin Yarn)와 셀룰로오스 디아세테이트 섬유를 사용하여 직물상태에서 우수한 부품성, 흡습성, 드레이프성, 신축성을 가지며 자연스러운 외관과 뛰어난 톤(Tone)효과를 가지는 폴리에스테르 태세사(Thick & Thin Yarn)/셀룰로오스 이수축 혼섬 직편물의 제조방법을 제공하는 것을 목적으로 한다.Therefore, the present invention has excellent parts properties, hygroscopicity, drape, elasticity in the fabric state using polyester thick yarn (Thick and Thin Yarn) and cellulose diacetate fibers without the problems of the prior art as described above and has a natural appearance and It is an object of the present invention to provide a method for producing a polyester thick & thin yarn / cellulose bishrink blended knitted fabric having an excellent tone effect.
본 발명은 심사로 사용되게 되는 치환도 2.0~2.75의 셀룰로오스 디아세테이트 섬유와 효과사로 사용되는 폴리에스테르 태세사(Thick and Thin Yarn)를 공기 교락하여 혼섬한 후 긴장 열처리하고, 얻어진 혼섬사로 직편물을 제직 또는 제편한 후 공정과, 제직 또는 제편된 직물을 알칼리 처리하여 셀룰로오스 아세테이트 섬유을 레이온으로 전환시켜서, 상기 심사와 효과사가 하기 수학식 1의 수축특성을 만족하는 것을 특징으로 하는 폴리에스테르 태세사(Thick and Thin Yarn)/셀룰로오스 이수축 혼섬 직편물의 제조방법.In the present invention, the cellulose diacetate fibers having a degree of substitution of 2.0 to 2.75, which are used as the screening, and the polyester thickener (Thick and Thin Yarn) used as effect yarns are intermingled by air interweaving, followed by tension heat treatment. Polyester weaving (Thick) characterized in that the process after the weaving or knitting, and alkali treatment of the woven or knitted fabric to convert the cellulose acetate fibers to rayon, the screening and effector satisfies the shrinkage characteristics of the following formula (1) and Thin Yarn) / method of producing a cellulose bishrink interwoven fabric.
SSP(H)는 긴장 열처리후 검화공정에서의 심사(고수축사)의 수축율(%)SSP (H) is the shrinkage rate (%) of the screening (high shrinkage) in the saponification process after tension heat treatment.
SSP(L)은 긴장 열처리후 검화공정에서의 효과사(저수축사)의 수축율(%)SSP (L) is the shrinkage rate (%) of the effect yarn (low shrinkage yarn) in the saponification process after tension heat treatment
이하, 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명은 폴리에스테르 태세사(Thick and Thin Yarn)/셀룰로오스 이수축 혼섬 직물을 제조하기 위하여, 이수축 혼섬사의 원료로써 셀룰로오스 디아세테이트를 심사로, 폴리에스테르 태세사(Thick and Thin Yarn)를 효과사로 사용하게 된다.The present invention is to examine the cellulose diacetate as a raw material of the biaxially mixed yarn, to prepare a polyester thickener (Thick and Thin Yarn) / cellulose bi-shrink blended fabric, the polyester yarn (Thick and Thin Yarn) as an effect yarn Will be used.
상기 셀룰로오스 디아세테이트는 치환도가 2.0~2.75인 것이 바람직하다.It is preferable that substitution degree of the said cellulose diacetate is 2.0-2.75.
또한, 본 발명에서는 심사로 사용되는 셀롤로오스와 효과사로 사용되는 폴리에스테르 태세사를 공기 교락한 후 혼섬하게 되며, 상기 혼섬사를 원사로 하여 직물을 제조하는 공정을 포함하는 것을 특징으로 한다. 본 발명에서의 직물은 편물을 포함하는 개념이다.In addition, the present invention is characterized in that it comprises a step of interweaving after air entangled with the cellulose used as the screening and the polyester posture yarn used as the effect yarns, characterized in that it comprises a step of producing a fabric using the blended yarn as yarn. The fabric in the present invention is a concept including a knitted fabric.
본 발명에서는 상기의 제직된 직물을 알칼리 처리하여 셀룰로오스 아세테이트 섬유를 레이온 섬유로 전환시키는 공정을 포함하는 것을 특징으로 하는데, 검화 후에 효과사(저수축사)와 심사(고수축사)가 수학식 1을 만족하는 것을 특징으로 한다.The present invention is characterized in that it comprises the step of converting the cellulose acetate fibers into rayon fibers by alkali treatment of the woven fabric, the effect yarn (low shrink yarn) and the screening (high shrink yarn) satisfy the equation (1) after saponification Characterized in that.
본 발명의 검화과정의 알칼리 조건은 셀룰로오스 디아세테이트 섬유 대비 32~40%의 알칼리 수용액에 70~130℃의 온도에서 1~120분 동안 1회 또는 2회 처리하는 것이 바람직하다.Alkaline conditions of the saponification process of the present invention is preferably treated once or twice in 1 to 120 minutes at a temperature of 70 ~ 130 ℃ in an aqueous alkali solution of 32 to 40% compared to the cellulose diacetate fiber.
상기와 같이 셀룰로오스 디아세테이트를 알칼리 처리하면 아세틸기 하이드록시기로 전환되는 검화가 일어나게 되는데 이때 무정형으로 존재하던 디아세테이트 섬유의 분자쇄들의 폴딩(folding)과 패킹(packing)등의 재배열로 결정화가 일어난다. 일반적으로 천연의 셀룰로오스는 셀룰로오스 I의 결정구조를 가지게 되며 재생 셀룰로오스섬유의 경우는 셀룰로오스 II의 구조를 가지는 데 반해 셀룰로오스 디아세테이트의 검화에 의해 제조된 셀룰로오스 섬유는 셀룰로오스 II와 IV가 혼합된 결정구조를 가지게 되며, 결정화도(비중법) 14~34%, 복굴절율 0.012~0.024이다.Alkaline treatment of cellulose diacetate as described above results in the saponification of conversion to an acetyl group hydroxy group, wherein crystallization occurs by rearranging and folding of molecular chains of diacetate fibers that were present in an amorphous form. In general, natural cellulose has a crystalline structure of cellulose I. In the case of regenerated cellulose fibers, cellulose II has a structure of cellulose II, whereas cellulose fibers prepared by saponification of cellulose diacetate have a crystalline structure of cellulose II and IV.
