Description

난연성 폴리아미드섬유의 제조방법Manufacturing method of flame retardant polyamide fiber

본 발명은 난연성 폴리아미드섬유의 제조방법에 관한 것으로서, 더욱 구체적으로는 난연제를 중합단계에서 카프로락탐에 첨가혼합시켜서 폴리아미드 중합체를 제조한 다음 이를 용융방사함을 특징으로 하는 것이다.The present invention relates to a method for producing a flame retardant polyamide fiber, and more specifically, to add and mix the flame retardant to the caprolactam in the polymerization step to produce a polyamide polymer, characterized in that the melt spinning.

종래의 제조방법은 일반적인 난연성 폴리아미드섬유의 경우에 방향족디아민과 방향족 디에시드 클로라이드로부터 액정중합체를 토출하여 방치한후 세정 및 분쇄하여 수분함유율이 50중량이상인 단섬유를 제조한 다음, 상기 단섬유를 1015중량정도의 난연제수용액에 침지시킨후 건조하여 난연성 방향족폴리아미드 단섬유를 제조하였다.Conventional manufacturing method in the case of general flame-retardant polyamide fibers by discharging the liquid crystal polymer from the aromatic diamine and aromatic dieside chloride, left to clean, and then pulverized, the water content is 50% After preparing the short fibers of more than 10 15 weight It was immersed in a degree of flame retardant solution and dried to prepare a flame retardant aromatic polyamide short fibers.

상기 방법은 난연제로 유기인화합물을 사용하므로 난연효과를 크게 발휘하지 못하였으며 사용되는 난연제가 관능기를 가지는 화합물이기 때문에 제조하기 어렵고 고가인 문제점이 있었다.The above method does not exhibit a great flame retardant effect because it uses an organophosphorus compound as a flame retardant, and it is difficult and expensive to manufacture because the flame retardant used is a compound having a functional group.

본 발명은 이와 같은 문제점을 해결한 것으로서 이하 상세히 설명하면 다음과 같다.The present invention solves such a problem as described below in detail.

본 발명은 카프로락탐에 대하여 10이하인 미세분말상태의 난연제 110중량를 첨가, 혼합하여 폴리아미드 중합체를 제조한 다음에, 상기 폴리아미드 중합체를 용융방사함을 특징으로 한다.The invention relates to caprolactam 10 Flame retardant in the state of fine powder 1 10 weight After adding and mixing to prepare a polyamide polymer, characterized in that the polyamide polymer is melt-spun.

본 발명에 사용되는 난연제는 유기인화합물이 아니고 할로겐 화합물인 데카브로모디페닐옥사이드(DBDPO)혹은 헥사브로모벤젠(HBB)이다.The flame retardant used in the present invention is not an organophosphorus compound but is a decabromodiphenyl oxide (DBDPO) or hexabromobenzene (HBB) which is a halogen compound.

본 발명에서 HBB를 사용할 경우에는 이것을 클로로벤젠등의 용매에 녹인 다음에 카프로락탐에 액상으로 공급하여 중합 및 용융방사할 수도 있다.When HBB is used in the present invention, it may be dissolved in a solvent such as chlorobenzene, and then supplied to the caprolactam in a liquid phase to perform polymerization and melt spinning.

본 발명은 난연제의 첨가량이 매우 중요하다.The amount of the flame retardant added is very important in the present invention.

만일 첨가량이 10중량를 초과하게 되면 조업성이 불량해지며, 1중량미만이면 난연효과가 불량하다.10 weight If exceeding, the operability becomes poor and 1 weight If less, the flame retardant effect is poor.

본 발명은 종래의 방법에 비하여 공정이 단축되므로 제조비용이 절감되며, 할로겐화합물인 난연제를 사용하므로 난연성이 우수하고 지속적으로 난연성을 발휘할 수 있다.The present invention reduces the manufacturing cost because the process is shorter than the conventional method, and because it uses a flame retardant which is a halogen compound, it is excellent in flame retardancy and can continuously exhibit flame retardancy.
