본 발명은 폴리에스테르 미연신사를 150 ∼ 210℃로 열처리하면서 1.0~ 1.15배로 연신한후 고수축 폴리에스테르 미연신사와 합사하고, 이것을 고기교락시킨다음 권취하는 폴리에스테르 복합가공사의 제조방법임.The present invention is a method for producing a polyester composite fabricated by stretching the polyester non-drawn yarn to 1.0 ~ 1.15 times while heat-treated at 150 ~ 210 ℃, then fused with a high shrink polyester undrawn yarn, the meat is entangled.
본 발명으로 제조된 복합가공사는 이후의 연사공정에서 연사작업성이 좋으며 염색시에 염색차이를 일으키지 않는다.The composite workpiece manufactured according to the present invention has good twistability in the subsequent twisting process and does not cause dyeing difference during dyeing.
Description
본 발명은 폴리에스테르 복합가공사의 제조방법예 관한 것이다.The present invention relates to a method for producing a polyester composite workpiece.
종래의 숭고성이 우수한 심초방식의 다층구조의 복합가연사는 두종류이상의 원사의 신도차이를 이용하여 동일한 가연영역에서 가연정도의 차이를 유발하여 신도가 낮은 원사는 복합가연사의 심(core)구조로 들어가고 신도가 높은 원사는 복합가연사의 초(sheath)구조로 들어가서 심사를 외곽에서 감싸는 구조를 지니게 된다.Conventional multi-layer composite twisted yarns having excellent sublime characteristics induce the difference in flammability in the same flammable area by using the difference in elongation of two or more kinds of yarns, and low elongation yarns enter the core structure of composite twisted yarns. High-yield yarns will enter the sheath structure of the composite twisted yarn and wrap around the screen.
위의 방식으로 제조한 가공사는 보통 심사(내층부)에 단사의 섬도가 큰 원사를 사용하고 초사(외층부)에 단사의 섬도가 작은 원사를 사용한것이므로 원사자체의 부피가 크고 사외층부에 루프가 많으므로 연사공정등에 서 작업성이 떨어져서 양산하는데 어려움이 많기 때문에 실용화하기가 어려웠다.Processed yarns manufactured by the above method usually use yarns with high single yarn fineness for screening (inner layer), and yarns with small fineness of single yarn for super yarn (outer layer). Because of the large number, it was difficult to put into practical use because of difficulty in mass production due to poor workability in the twisting process.
본 발명은 상술한 바와같은 문제점을 해결한 것으로서, 가공사자제의 부피가 적고 염색차를 발생시키지 않으며 연사(twisting)공정까지는 일반원사처럼 표면이 비교적 평할하다가 염색가공시에 루프가 발현되는 폴리에스테르 복합가공사의 제조방법을 제공하는데 그 목적이 있다.The present invention is to solve the problems described above, a small amount of processed yarn, does not cause dyeing difference, and until the twisting (twisting) process, the surface is relatively flat like a normal yarn, the loop is expressed during dyeing processing Its purpose is to provide a method for manufacturing composite processing.
본 발명을 예시한 도면에 의거 상세히 설명하면 아래와 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 복합가연을 하지 않고도 복합가연을 한것과 같은 제품특성을 갖는 복합가공사의 제조방법으로서 열수축성이 큰 폴리에스테르사와 폴리에스테르 미연신사를 단순 열처리, 공기교락을 부여하여 제조함을 특징으로 한다.The present invention is a method of manufacturing a composite workpiece having the same product characteristics as composite composite without performing composite composite, characterized in that it is produced by applying a simple heat treatment, air entrained polyester yarn and polyester non-stretched yarn having a large heat shrinkability .
도 1 된 표시한 바와같이 본 발명은 열수축성이 뛰어난 폴리에스테르필라멘트 연신사(비수수축율 30%이상)와 폴리에스테르 필라멘트 미연신사를 사용한다.As shown in Fig. 1, the present invention uses polyester filament drawn yarn (non-shrinkage ratio of 30% or more) and polyester filament undrawn yarn having excellent heat shrinkability.
즉 복굴절율이 30x10-3 ~ 70x10-3인 폴리에스테르 미연신사를 연신비1.00 ∼ 1.15로 열연신하여 열에 대한 수축성을 없에 주고, 이를 열수축성이 뛰어난 폴리에스테르 필라멘트 연신사와 동일 로울러(FR2)상에서 합사한 다음에 인터레이서에서 공기압력 3.0 ∼ 3.8kg/㎠으로 공기교락을 부여하고 권취하여 복합 가공사를 제조한다.In other words, the non-stretched polyester having a birefringence of 30x10 -3 to 70x10 -3 is thermally stretched at a draw ratio of 1.00 to 1.15 to give no shrinkage to heat, which is then spliced on the same roller (FR 2 ) as the polyester filament drawn yarn having excellent heat shrinkability. Thereafter, air interlock is applied at an interlacer at an air pressure of 3.0 to 3.8 kg / cm 2, and wound to produce a composite yarn.
본 발명에서 후가공시에 미연신사에 의한 염색줄이 발생되지 않도록 온도 및 연신비를 설정해주어야 하는데 열처리온도는 150 ∼ 210℃ 연신비는 1.00 ∼ 1.15로 한다.In the present invention, the temperature and the draw ratio should be set so that the dyeing line by the undrawn yarn does not occur during post-processing, the heat treatment temperature is 150 ~ 210 ℃ draw ratio is 1.00 ~ 1.15.
열처리 온도가 상기 범위를 벗어나면 가공사의 2성분 혼합에 따른 염색성 차이가 발생하고, 연신비가 1.15배를 초과하면 가공사의 촉감이 일반 필라멘트사처럼 불량해져서 숭고성이 뛰어난 가공사를 제조할 수 가 없다.When the heat treatment temperature is out of the above range, the difference in dyeing property due to the mixing of the two components of the processed yarn occurs, and when the draw ratio exceeds 1.15 times, the touch of the processed yarn becomes as bad as that of the normal filament yarn, and thus it is impossible to manufacture the processed yarn having excellent sublime properties.
특히 가공사가 외관상으로 루프등의 불량이 없도록 하기 위해서는 조합되는 사종별로 적정한 연신비와 온도, 공기교락 조건, 권취조건을 설정해 주어야만 한다.In particular, in order to avoid the appearance of loop defects, the processor must set the proper draw ratio, temperature, air entrainment, and winding condition for each type of combination.
본 발명으로 제조한 복합가공사를 연사하여 열고정하고 제직하여 염가공하면 열수축성이 뛰어난 폴리에스테르 연신사가 수축하고 폴리에스테르미연신사는 자발신장하여 숭고성이 뛰어난 원사를 제조할 수 있다.When the composite work manufactured by the present invention is twisted, heat-set, weaved, and salted, polyester drawn yarns having excellent heat shrinkability shrink and polyester undrawn yarns can be spontaneously expanded to produce yarns having excellent sublime properties.
