Abstract

본 발명은 콘베어벨트지를 제조할 때 주름 및 겹침현상을 일으키지 않으며 크림프율의 저하가 없도록 하기 위하여 콘베어벨트지를 구성하는 위사를 특정조건의 것으로 사용하며 상기 특정조건을 만족할 수 있도록 위사를 제조함을 특징으로 하는 것이다.The present invention uses the weft constituting the conveyor belt paper as a specific condition in order not to cause wrinkles and overlapping phenomenon and to reduce the crimp rate when manufacturing the conveyor belt paper, characterized in that to produce a weft yarn to satisfy the specific conditions It is to be done.

본 발명의 위사는 강도 7.5g/d 이상, 절단신도 40%이상, 및 건축수축율 3% 이하의 것이며 다음과 같이 제조하는 것이다.The weft of the present invention has a strength of at least 7.5 g / d, an elongation at break of at least 40%, and a building shrinkage rate of at most 3%, and is prepared as follows.

즉 상대점도가 3.0~3.4인 나이론 6칩으로 미연신사를 만든 다음에 전연신배율 3.5~4.0배로 2단연신하되 2단연신사의 가열온도는 190~220℃로 하며 이완율이 10~14%가 되도록 이완처리하여 제조한다.In other words, unstretched yarn is made of nylon 6 chip with relative viscosity of 3.0 ~ 3.4, and then stretched in two stages with 3.5 ~ 4.0 times full extension ratio, but heating temperature of two stages is 190 ~ 220 ℃ and relaxation rate is 10 ~ 14%. It is prepared by relaxing treatment as much as possible.
