Abstract: 본  발명은  토출된  폴리에스터사속을  냉각고화시킨후  2,000 ∼ 4,000m/분의  방사속도로  방사하되,  하나의  사속(絲束)은  비가열영역에  통과시켜서  고수축사속을  만들고,  다른  사속은  가열영역에  통과시킨후  오일링으로  집속하여  저수축사속을  만든다음,  두 개의  사속을  합사한후  공기교락시켜서  제조함을  특징으로 하는  이수축혼섬  폴리에스터  필라멘트사의  제조방법임. 
     본  발명은  방사장력을  증가시킴이  없이  공정품질이  우수하게  저렴한  비용으로  폴리에스터 이수축혼섬사를  제조할 수있다. 
     또  본발명의  이수축혼섬사는  수축율차가  30%이상일  뿐만아니라  자발신장특성을  갖는  고수축사를  가지므로  품질이  우수한  이수축혼섬직물을  만들 수 있다.

Abstract: 본 발명은 내흑변성, 내흑화성이 우수한 내지문강판용 수지용액의 제조방법 및 이 수지용액을 이용한 수지피복강판의 제조방법에 관한 것이며; 그 목적하는 바는 고분자량의 에폭시수지에 MHP(3-methyle 5-hydroxy pyrazole) 또는 MHP와 초산아연이 혼합된 방청첨가제를 일정함량 첨가함으로써, 제품의 표면품질에 악영향을 미치지 않고, 코팅작업성이 우수하면서, 내흑변성 및 내흑화성이 우수한 내지문강판용 수지용액 및 이를 이용한 수지피복강판의 제조방법을 제공하는데 있다. 
     상기 목적을 달성하기 위한 본 발명은 아연도금강판에 크로메이트처리를 한후 도포되는 내지문강판용 수지용액을 제조하는 방법에 있어서, 실리카를 에틸렌-아크릴 수지함량 대비 10-20phr로 투입하여 화학적으로 결합시켜 주제용액을 제조하고, 이 주제용액에 분자량이 900-1500인 에폭시수지를 주제용액 함량대비 3-5phr 투입하고, 여기에 MHP를 0.03-1.3phr첨가하거나, 또는 MHP와 초산아연을 부피비로 25:75-35:65 비율로 하여 0.03-1.3phr 첨가하는 내지문강판용 수지용액의 제조방법 및 이 수지용액을 이용한 수지피복강판의 제조방법에 관한 것을 그 요지로 한다.
