Abstract

用于后凝聚纺的扇形纺丝毛细管通过在每个扇形槽的每个矩形槽的底部增加一个内弓形槽则能提供纺圆形截面的长丝，该长丝沿长度方向具有圆形连续空隙。

Description

本发明涉及一种喷丝头，更确切的说它涉及的是用于纺基本上为圆型长丝的喷丝头，该圆型长丝沿着它们的长度具有许多轴向空隙。
1987年11月13日在美国申请尚未批准的，申请号为120438，其申请是关于一种新的聚酯填充纤维，它包括沿着长丝长度上有连续的多空隙，特别的是，描述了基本上是圆形横截面的聚酯填充纤维，沿着长丝的长度上至少具有7个圆形横截面的连续的空隙，一个空隙位于中心，而其余的空隙相互基本是相同的尺寸，并基本上是相同的间隙围绕中心空隙，且在长丝的周围。
用于生产象长丝的喷丝头有一个喷丝板组成，该喷丝板具有上表面和下表面，并由一毛细管连接，该毛细管由许多扇形形成，每一扇形由外弓槽和内弓槽组成，弓形槽相互联系是由一个矩形槽连接，这些扇形距毛细管的中心为相等的距离，并且在毛细管的中心周围是等空隙的角度。在一个最佳实施例中，矩形槽连接内外弓形槽，并且是在中心位置连接它们，它具有一定的宽度，这个宽度比内弓形槽的宽度大，而外弓形槽的宽度比连接于内弓形槽和外弓形槽的矩形槽的宽度大。这个喷丝头是一块喷丝头，它避免了多部分喷丝头的不利影响，并且它适合于成形空心纤维。
图1和图2分别表示的是本发明的喷丝头的侧视图和下表面图;
图3是图1和图2喷丝头的下表面毛细管的放大示意图。
现参照图1-3，喷丝头20是适合安装在过滤组件上（未图示）用于提供聚酯以纺成长丝。喷丝头20是由板22所形成，并且设有许多毛细管24，该管分别连接于上下表面26和28。毛细管24分别由所标的40、50、60、70、80和90六个扇形所构成，每个扇形距毛细管中心C都有相等距离d，并且是以角度A等间距角度围绕中心C，每个扇形是同样的尺寸，扇形40将在下面详细描述，特别地是扇形40包括一个外弓形槽42，并由另一个槽43连接于内弓形槽43。
在毛细管24较好的结构中，槽43的宽度48比内弓形槽44的宽度46大，外弓形槽42的宽度49比槽43的宽度48大。
典型的毛细管具有0.062″的外径D，0.012″的长径d，和大约60°角度A。宽度46、48和49的相关尺寸如下：宽度48大约是宽度46的1.1倍，宽度49大约是宽度46的1.2倍。

Claims (3)

1、用于生产基本上圆形横截面的长丝的喷丝头，在沿着长丝方向上至少有7个连续的空隙，一个空隙位于中心，所说的喷丝头是由一个具有上下表面的板组成，该板的上下表面是由一毛细管连接，在所说的下表面上的毛细管是由许多相等间距的扇形所确定，并且在毛细管的中心周围是等空隙角度，每个所说的扇形由一个内弓形槽并由另一槽连接于包弓形槽所构成。
2、根据权利要求1的喷丝头，它具有六个扇形。
3、根据权利要求2的喷丝头，其中所说的连接于内弓形槽和外弓形槽的槽是一矩形，并且具有一宽度，其宽度比内弓形槽宽度大，所说的外弓形槽具有的宽度比连接于内外弓形槽的宽度大。
