Description
본 발명은 이종물성을 가진 폴리에스테르 필라멘트의 동시가연가공방법에 관한 것으로서 심사와 효과사의 가연을 동시에 한꺼번에이 행하는 방법에 관한 것이다.The present invention relates to a method for simultaneous pre-casting of polyester filaments having different physical properties, and relates to a method for simultaneously performing judging and false twisting of an effect yarn.
일반적으로 수축율 및 기타 물성이 상이한 2종의 폴리에스테르 필라멘트를 가연장치에 의해 연신가연을 하고 교락함으로써 수축율의 차이에 의한 벌키감 및 신도를 부여하고 이염현상에 의한 멜란지 효과를 얻을 수 있는 가연복합사가 개발되고 있다.In general, a false twist yarn capable of obtaining a melange effect due to a dyeing phenomenon by imparting bulkiness and elongation due to difference in shrinkage ratio by stretching, twisting and entangling two polyester filaments having different shrinkage ratios and different physical properties with a false twisting device Is being developed.
종래에는 효과사로 폴리에스테르 미연신 필라멘트를 사용하여 다른 종류의 합성섬유사를 심사로 하여 복합사를 제조하는 경우에는 효과사와 심사를 따로따로 가연한 후 인터레이스하는 경우가 많았다. 특히 대한민국특허등록제10-0723341호에서도 효과사로 폴리에틸렌테레프탈레이트 부분연신 필라멘트(PET POY)를 제1피드롤러를 통과시키고, 히터에서 열처리온도는 180∼200℃로 열처리한 후 냉각판을 거치면서 냉각하고, 가연을 하면서 연신하고, 심사로 폴리트리메틸렌테레프탈레이트(PTT) 미연신 필라멘트를 제2피드롤러를 통과시켜 제3피드롤러로 공급하고, 상기 효과사와 심사를 인터레이스한 후 오일처리하고 권취하여 폴리에스테르 복합가연사를 제조하고 있다. 이러한 선행기술의 경우에는 공정상의 번거로움, 비용증가의 문제점이 발생하였고, 최종 생산되는 복합가공사의 교락의 안정화가 어려운 문제점이 있었다.Conventionally, in the case of producing a composite yarn by examining other kinds of synthetic fiber yarns using polyester unstretched filaments, there have been many cases in which interlacing is effected after separately waving the effect yarn and the judging yarn. Particularly, in Korean Patent Registration No. 10-0723341, a polyethylene terephthalate partially drawn filament (PET POY) is passed through a first feed roller, heat treatment is performed at a temperature of 180 to 200 占 폚 in a heater, followed by cooling while passing through a cooling plate (PTT) unstretched filaments are passed through a second feed roller and fed to a third feed roller. The resultant is subjected to interlacing with the above-mentioned effect yarn, followed by oil treatment and winding to obtain poly (methylene terephthalate Ester composite yarn. In the case of this prior art, there are problems in process hassle and cost increase, and there is a problem that it is difficult to stabilize entanglement of a composite construction work to be produced.
그러므로 본 발명에서는 심사와 효과사의 가연을 동시에 한꺼번에 함으로써 공정단순화를 도모하고, 최종 생산되는 복합가공사의 교락의 안정화를 이루도록 하고 우수한 멜란지발현을 이루도록 하는 동시가연가공방법을 제공하는 것을 기술적과제로 한다.Therefore, in the present invention, it is a technical object to provide a simultaneous pre-fusing processing method for simplifying a process by simultaneous judging and false-twisting of an effect yarn, stabilizing entanglement of the finally produced multifunctional construction, and achieving excellent melange appearance.
그러므로 본 발명에 의하면, 심사인 캐치온 가염성 폴리에스테르 필라멘트와 효과사인 폴리에스테르 미연신 필라멘트를 공급하여 제1차인터레이스하고 170~210℃로 제1차열처리한 후, 가연을 한 후, 제2차인터레이스하는 것을 특징으로 하는 이종물성을 가진 폴리에스테르 필라멘트의 동시가연가공방법이 제공된다.Therefore, according to the present invention, the first interlaced first heat treatment is carried out by supplying the catch on polyester non-drawn filament and the polyester non-drawn filament which is the effective yarn, and then subjected to the first heat treatment at 170 to 210 DEG C, The present invention provides a method for simultaneous flameproofing of polyester filaments having different properties.
이하 본 발명을 보다 상세히 설명하기로 한다. Hereinafter, the present invention will be described in more detail.
본 발명의 이종물성을 가진 폴리에스테르 필라멘트의 동시가연가공방법은 심사인 캐치온 가염성 폴리에스테르 필라멘트와 효과사인 폴리에스테르 미연신 필라멘트를 공급하여 제1차인터레이스하고 170~210℃로 제1차열처리한 후, 가연을 한 후, 제2차인터레이스하는 것을 특징으로 하는데, 본격적인 인터레이스전에 예비인터레이스공정(본 발명에서는 "제1차인터레이스"라 한다.) 및 예비열처리(본 발명에서는 "제1차열처리"라 한다.)를 행하고 가연 및 제2차인터레이스를 하여 심사와 효과사의 가연을 동시에 한꺼번에 함으로써 공정단순화를 도모하고, 최종 생산되는 복합가공사의 교락의 안정화를 이루도록 하고 우수한 멜란지발현을 이루도록 하는 것을 특징으로 한다.The method for simultaneous flameproofing of polyester filaments having different physical properties according to the present invention is characterized in that a catch on cotton filament polyester filament and a polyester non-drawn filament as an effect yarn are fed first, interlaced first and then subjected to a first heat treatment The first interlacing process (referred to as "first order interlace" in the present invention) and the preliminary heat treatment (referred to as "first heat treatment " in the present invention) before the full interlace, "), Performs a false-twitch and a second-order interlace to simultaneously simplify the process by simultaneous examination and false twisting of the effect yarn, stabilize entanglement of the finally produced composite yarn construction, and achieve excellent melange appearance .
본 발명에서 심사로 사용되는 캐치온 가염성 폴리에스테르 필라멘트는 폴리에스테르 사슬에 음이온기를 도입하여 양이온염료와 비교적 쉽게 결합시키킬 수 있는 것으로서 술폰산 금속염기를 포함하고 있는 이관능성 카르본산 또는 디올에서 유도된 에스테르 단위등을 공중합시킨 공지의 캐치온 가염성 폴리에스테르 필라멘트를 사용할 수 있다.Catch-on weighed polyester filaments used in the present invention can be relatively easily combined with cationic dyes by introducing an anionic group into the polyester chain. The catechophilic polyester filaments can be easily coupled with cationic dyes by using a bifunctional carboxylic acid or a diol derived from a sulfonic acid metal base Ester units, and the like can be used.
효과사로 공급되는 폴리에스테르 미연신 필라멘트는 복합가공사의 외층(Effect)을 구성할 목적으로 방사 단계에서 고속방사방법으로 자발 신장을 극대화하여, 저 수축 효과를 부여하고, 외층 부위 사가 솜털같이 부드러운 질감을 유지 할 수 있도록 제조된 것으로서 방사속도 5,000 ~ 5,500m/min으로 제조된 POY사를 사용하는 것이 좋다.The polyester unstretched filament supplied as an effect yarn maximizes the spontaneous elongation by a high-speed spinning method at the spinning stage for the purpose of constituting the outer layer of the composite construction work, and gives a low shrinking effect. It is recommended to use POY yarn manufactured at a spinning speed of 5,000-5,500 m / min.
본 발명에서 복합가공사는 도 1에 도시된 공정도에서와 같이 심사(1)인 캐치온 가염성 폴리에스테르 필라멘트와 효과사(2)인 폴리에스테르 미연신 필라멘트를 제1피드롤러로 함께 공급하고, 제1인터레이스장치(3)를 통과시켜 제1차인터레이스한 후, 170~210℃의 제1차열처리장치(4)를 통과시켜 제1차열처리한 후, 가연장치(5)를 통과시켜 가연을 한 후, 제2인터레이스장치(6)를 통과시켜 교락수 80 ~ 95개/m가 되도록 제2차인터레이스하고 170~210℃의 제2차열처리장치(7)를 통과시켜 제2차열처리한 후 권취롤러(8)에 권취하여 제조하게 된다.In the present invention, as in the process shown in Fig. 1, the composite processed yarn is fed together with the catch-on virgin polyester filament (1) and the polyester unstretched filament (2) First interlaced by passing through a
본 발명에서는 예비인터레이스공정이라 할 수 있는 제1차인터레이스공정에 의해 제1차히터전에 예비적인 교락을 부여하며, 제1차열처리를 통하여 최종 생산되는 복합가공사에서 균일성을 이루도록 한다. 상기 제1차인터레이스는 인터레이스노즐의 구경이 1.2~1.4 ㎜, 에어압이 1.3~ 1.5kg/㎠인 것을 사용하는 것이 복합사의 인터레이스발현을 원활히 할 수 있어 바람직하다.In the present invention, preliminary interlacing is given to the first heater by the first interlacing process, which can be called a preliminary interlacing process, and uniformity is achieved in the composite construction work which is finally produced through the first heat treatment. It is preferable that the interlaced nozzle of the first primary interlace has a diameter of 1.2 to 1.4 mm and an air pressure of 1.3 to 1.5 kg / cm 2 to facilitate the interlace expression of the composite yarn.
상기 제1차열처리장치(4)는 접촉식열처리기구를 사용하고, 상기 제2차열처리장치(7)는 비접촉열처리를 사용하는 것이 생산되는 복합가공사의 열적안정성을 확보할 수 있어 유리하며, 온도 180℃를 초과하게 되면 염색가공시 수축률이 급격히 저하될 우려가 있다. The first heat treatment apparatus (4) uses a contact type heat treatment mechanism, and the second heat treatment apparatus (7) is advantageous because it can secure thermal stability of the composite construction work in which the non-contact heat treatment is used, If the temperature is higher than 180 ° C, the shrinkage rate during dyeing processing may be sharply lowered.
본 발명에서는 상기 제1차열처리한 후, 가연(5)을 하여 bulky성을 부여 한 후 제2인터레이스장치(6)를 통과시켜 멜란지효과를 나타나게 한다.In the present invention, the first heat treatment is followed by the twisting (5) to give a bulky property and then the second interlacing device (6) causes the melange effect to be exhibited.
본 발명에서는 상기 제1차인터레이스는 인터레이스노즐의 구경이 1.2~1.4 ㎜, 에어압이 1.3~1.5kg/㎠이고, 상기 제2차인터레이스는 인터레이스노즐의 구경이 1.2~1.4 ㎜, 에어압이 0.9~1.2kg/㎠ 인 것을 사용하는데, 제2차인터레이스의 공기압력을 제1차인터레이스의 공기압보다 약하게 하여 교락수의 변동계수를 낮추어 교락의 안정화를 이루도록 하는 것이 중요하다.In the present invention, the first interlace has a diameter of 1.2 to 1.4 mm and an air pressure of 1.3 to 1.5 kg / cm 2. The second interlace has an interlace nozzle having a diameter of 1.2 to 1.4 mm, an air pressure of 0.9 To 1.2 kg / cm 2, it is important that the air pressure of the second interlace is made weaker than the air pressure of the first interlace so as to lower the coefficient of variation of the interlocking water to stabilize entanglement.
상기 심사인 캐치온 가염성 폴리에스테르 필라멘트와 폴리에스테르 미연신 필라멘트의 공급시 오버피드율은 0.02~0.05%인 것이 바람직한데, 오버피드율 0.02%미만에서는 모우발생의 문제점이 발생하며, 0.05%초과시에는 loop가 발생하는 문제점이 발생한다. It is preferable that the over feed rate of the catch on thermoplastic polyester filament and the polyester unstretched filament is in the range of 0.02 to 0.05%. When the over feed rate is less than 0.02%, a problem of mold generation occurs, There arises a problem that a loop occurs.
그러므로 본 발명에 의하면, 심사와 효과사의 가연을 동시에 한꺼번에 함으로써 공정단순화를 도모하고, 최종 생산되는 복합가공사의 교락의 안정화를 이루도록 하고 우수한 멜란지발현을 하는 물성이 다른 두 종류의 폴리에스테르의 동시가연방법을 제공할 수 있다.Therefore, according to the present invention, it is possible to simplify the process by simultaneous judging and erroneous evaluation of the effect yarn, to stabilize entanglement of the composite yarn produced in the final production, and to simultaneously produce two kinds of polyester yarns having different properties, Can be provided.
