The heat treatment step is performed at temperature of 140-170°C, and the relaxed-heat treatment step is at 170-210°C. A false twisting step is not used by the process for producing a polyester rewinding fiber. An equipment for producing a polyester crimped yarn has a supplying roller, a first heat, an interlacer, a second heater and a rewinding machine.

Description

폴리에스테르 권축가공사의 제조방법Manufacturing method of polyester crimping work

본 발명은 권축성과 자발신장성을 동시에 보유하고 있는 폴리에스테르 권축가공사의 제조방법에 관한 것이다.The present invention relates to a method for producing polyester crimping fabric that has both crimp and spontaneous elongation.

종래에는 자발신장성을 갖는 사와 열수축성이 큰 사(고수축사)를 혼섬하여 제조한 가공사를 사용하여 직, 편한 후 염가공할 때 열수축성이 큰 사(고수축사)는 수축하여 직, 편물의 내부에 숨게하고 자발신장성을 갖는 사는 직, 편물의 표면에 부상되도록 하여서 숭고성이 우수한 직, 편물을 제조하여왔다.Conventionally, using a processed yarn manufactured by mixing a spontaneous stretchable yarn with a high heat shrinkable yarn (high shrink yarn), the high heat shrinkable yarn (high shrink yarn) is shrunk when weaving the fabric after weaving the fabric. It has been manufacturing excellent weaving, knitted fabric to hide inside and to have a spontaneous stretch to the surface of the knitted fabric, knitted fabric.

일반적으로 자발신장성사는 폴리에스테르 미연신사와 고배향 미연신사에 결정화도를 대폭 증대시켜 배향을 부여하는 연신공정을 거치고 2 차로 10 ∼ 20%의 오버피드율로 과공급하면서 열처리한후 완화열처리하여서 제조하여왔다.In general, spontaneous elongation yarn is manufactured by heat-treating heat treatment after overfeeding with overfeed rate of 10 to 20% by secondly stretching process to give orientation by increasing the degree of crystallinity to polyester unstretched yarn and highly oriented unstretched yarn. Has been.

위와같은 공정으로 권축가공사를 제조하는 경우에 완화열처리공정과 가연가공을 함께 실시하여야함으로 제사작업성도 좋지 못하였으며 또 안정된 물성을 갖는 권축가공사를 제조하기가 매우 어려웠다.In the case of manufacturing the crimping process by the above process, it is difficult to manufacture the crimping work with stable physical properties because it has to perform the heat treatment process and the flammable processing together.

왜냐하면 가연공정은 일반적으로 높은 장력을 필요로 하지만 완화열처리공정은 낮은 장력을 필요로 하기 때문에 동일 가연기내에서 1 단계공정으로 가연권축성과 자발신장성을 갖는 권축가공사를 제조하기가 어렵다.Because the combustion process generally requires high tension, but the mild heat treatment process requires low tension, it is difficult to manufacture crimping work with flammability and spontaneous elongation in one step process in the same combustor.

본 발명은 가연공정없이도 후가공 공정에서 가연권축성과 자발신장성을 동시에 발현시키며, 또 이와같은 권축가공사를 우수한 제사작업성으로 제조할 수 있는 폴리에스테르 권축가공사의 제조방법을 제공하는데 그 목적이 있는 것이다.The present invention is to provide a method for producing a polyester crimping work that can simultaneously express the flammability and spontaneous elongation in the post-processing process without a flammable process, and can produce such crimping work with excellent spinning workability. It is.

본 발명을 예시도면에 의하여 상세히 설명하면 다음과 같다.The present invention will be described in detail by way of example.

도 1에 표시한 바와같이 복굴절율이 30 × 10-3∼ 90 × 10-3인 폴리에스테르 미연신사를 공급로울러(1)과 공급로울러(3)사이에서 140 ∼ 170℃의 제 1 히터(2)에서 열처리하면서 1.05 ∼ 1.10배로 연신하며, 또 별도로 공급되는 비수수축율이 30%이상인 고수축성 폴리에스테르사를 공급로울러(3)에 인입시켜서 상기 폴리에스테르사와 합사시킨후 인터레이서(4)에서 3.0 ∼ 3.5kg/cm2의 공기압력으로 공기교락시킨다.As shown in FIG. 1, a first heater 2 having a birefringence of 30 × 10 -3 to 90 × 10 -3 between the feed roller 1 and the feed roller 3 between 140 and 170 ° C. E) is stretched from 1.05 to 1.10 times while heat-treated in the same), and a highly shrinkable polyester yarn having a non-shrinkage ratio of 30% or more supplied separately is introduced into the feed roller 3, and then spliced together with the polyester yarn, and then 3.0 to 3.0 in the interlacer (4). Air immersion with an air pressure of 3.5 kg / cm 2 .

이어서 상기 공기교락사를 공급로울러(3)와 공급로울러(6)사이에서 10 ∼ 16%의 오버피드율로 과공급하면서 제 2 히터(5)에서 170 ∼ 210℃로 열처리하여 이완열처리한 다음에 권취기(7)에서 권취한다.Subsequently, the air entangled yarn was heat-treated at 170 to 210 ° C. in the second heater 5 while being oversupplied between the supply roller 3 and the supply roller at an overfeed rate of 10 to 16%, and then thermally relaxed. It winds up in the winder (7).

본 발명은 폴리에스테르 미연신사가 열처리후 공기교락처리된 다음에 다시 이완상태에서 1 차 열처리온도보다 30 ∼ 50℃정도 높은 온도에서 2 차로 열처리되므로 이후의 염가공공정에서 자발신장성을 쉽게 발현시킨다.The present invention is easy to express spontaneous elongation in the subsequent dyeing process because the polyester undrawn yarn is heat-treated secondly at a temperature of about 30 to 50 ℃ higher than the first heat treatment temperature in the relaxed state after air-treating after heat treatment .
