Abstract

本实用新型提供一种蜂房型中空喷丝板,喷丝板上的喷丝孔外部结构为圆形,内部设置3~36实心正六边形,实心正六边形有间隙,间隙与外圆均为中空部分,形成喷丝孔,实心正六边形面积为圆形的1/3~4/5,每个喷丝板上设置4~90个喷丝孔,这样由于喷丝孔内部为多个正六边形,所纺纤维具备蜂房式中空结构,具有蓬松功能和高弹性强度,而喷丝孔正六边形是实心,所纺纤维则为空心,具备保温、轻质功能,广泛用于功能性化纤织造。

Description

蜂房型中空喷丝板
技术领域
本实用新型涉及一种喷丝板,尤其是中空喷丝板。
背景技术
喷丝板又称纺丝帽。喷丝板的作用是将黏流态的高聚物熔体或溶液,通过微孔转变成有特定截面状的细流,经过凝固介质如空气或凝固浴固化而形成丝条。按纤维的类别和规格不同,有不同的规格、形状、孔型、材质等。喷丝板在较高的温度和压力下工作。要求耐压、耐腐蚀和足够的机械强度。喷丝板可分:(1)普通型,其中又可分为熔纺喷丝板(其外形有圆形、矩形、扇形)和湿纺喷丝板(又称喷丝帽);(2)异形喷丝板,纺制纤维的断面是非圆形的;(3)复合喷丝板以制造复合纤维。
但目前的中空喷丝板纺出的纤维结构比较单一,纤维蓬松性比较差,弹性强度低。
发明内容
本实用新型目的在于提供一种中空喷丝板,使所纺出来的纤维具备蓬松性,弹性强度。
一种蜂房型中空喷丝板,其特征在于喷丝板上的喷丝孔外部结构为圆形,内部设置3~36实心正六边形,实心正六边形有间隙,间隙与外圆均为中空部分,形成喷丝孔,实心正六边形面积为圆形的1/3~4/5,每个喷丝板上设置4~90个喷丝孔。
由于喷丝孔内部为多个正六边形,所纺纤维具备蜂房式中空结构,具有蓬松功能和高弹性强度,而喷丝孔正六边形是实心,所纺纤维则为空心,具备保温、轻质功能。
附图说明
附图为蜂房型中空喷丝板结构示意图。
其中:1,喷丝板;2,喷丝孔;3,实心正六边形。
具体实施方式
下面结合附图对本实用新型进行说明:在具体实施过程中,将黏流态的高聚物熔体或溶液,通过喷丝板1的喷丝孔2中喷出,转变成有特定截面状的细流,由于喷丝孔内设置有多个实心正六边形3,纤维就具有蜂房型结构,具有蓬松、高弹性强度、保温、轻质等性能。
具体实施中,由于喷丝板的喷丝孔是环形结构,可以设置薄的连接线固定中间的实心部分,在喷丝过程中,纤维离开喷丝板时会自动黏结一起。
