Description

用于制造碰撞缓冲气垫的无涂层织物及其制造方法
本发明涉及用于制造碰撞缓冲气垫(气袋)的单丝纤度为1.5-7dtex，纤度强度为(50-80)×10-2N/tex和伸长率为30％聚酰胺长丝纱制的平纹-或重平组织的无涂层织物以及它的制造方法。
由聚酰胺6.6制的无涂层织物是已知的(EP-A-0436950)。在此要达到微小的空气透过性，显然要求在织物中要采用在160℃测定的热空气收缩为6-15％的长丝。粗织物随即在一水浴中、在温度范围为60和140℃之间进行突然收缩。但是用此已知方法，平纹织物的空气透过性在500Pa只能达到3和大于3升/分米2/分钟，这本身是微小的，由气袋系统制造厂所要求的空气透过性对于许多用途已足够，所需的纱线由于高热收缩和因此造成的高卷绕张力而不能用或只能很困难用纺牵法制造。
在应用高收缩纱(超过60％)时，在制造中要注意采取特别的措施，即通过强烈而均匀的冷却来固定热收缩使之不产生张力差。牵伸或是通过带有丝条张力控制冷却的丝速牵伸来进行，或者往往在纱管成形中通过垂直的单丝牵伸进行。对这种纱线，在实践中要求从纱管倒筒成圆筒或要求带有张力控制的冷却进行丝束牵伸。
本发明的任务是提供一种织物，这种织物的空气透过性接近相当于涂层织物的空气透过性，并且可用简单的因而也是经济的方法制造。此空气袋织物应具有非常小的空气透过性，高尺寸稳定性和高断裂强度。
另一个任务是，寻找以不涂层织物作为涂层织物代用品，用于制造空气袋织物，涂层不仅是耗费大和昂贵的方法，而且得到的织物可折叠性低劣10-15％，且包装体积大。
本发明的任务是这样解决的，织物同时具有空气透过性＜3升/分米2/分钟，剩余沸水收缩＜2％和经纱和纬纱撕破强度＞110N。适当的空气透过性为1-3升/分米2/分钟。
织物以5cm的织物条子形式测定的撕拉(断裂)力大于2500N是适当的，这样才能保证空气袋织物在碰撞时具有安全性。
一种用纺牵法制造的单丝纤度为1.5-1.7dtex的聚酰胺复丝纱表明特别适用于制造无涂织物的方法中。其中特别具有优点的是，在160℃的空气中和在0.5×10-2N/tex的预张力下测定聚酰胺长丝纱的热空气收缩为＜6％。然后作为织物放在密闭的容器中，在温度从80-160℃和相对空气湿度为90-100％的条件下进行处理。
惊奇地发现，用低收缩的原料也可达到很小的空气透过性。空气透过性超过3升/分米2/分钟对具有较少的和较细粒子的解开系统只是在一定条件下是允许的；空气透过性在3升/分米2/分钟以下，优选在2.5升/分米2/分钟和更少时，证明对空气袋织物为最优。
织物的空气透过性按德国工业标准DIN 53887、在空气压力为500Pa下进行测定。
热收缩和沸水收缩按德国工业标准DIN 53866测定，其中热收缩的测定时，空气温度为160℃，预张力为0.5×10-2N/tex。撕裂强度是按德国工业标准DIN 53859T2测定，撕拉(断裂)力和断裂伸长按德国工业标准DIN 83835测定。
作为原料采用无松毛球的用纺牵法制造的聚酰胺长丝纱，它的单丝纤度范围为1.5-7dtex，特别是3dtex或更细。特别必要的是，聚酰胺长丝的热空气收缩为＜6％，尤其是为＜5.5％，这是在160℃和0.5×10-2N/tex的预张力下测得的。同时，按德国工业标准DIN 53866在160℃测得的最小收缩力为0.2×10-2N/tex。用这样的低收缩纱例如有可能制造和成功地加工5-15kg纺牵园形筒子的大卷装。用已知的方法制成平纹组织和重平织组的织物，然后将织物放在一个密封的容器中，在温度为80-160℃和相对空气湿度为90-100％时进行处理。
本发明借助于一些实例予以进一步说明
