本发明涉及净化房间清洁织物，它是由单位面积重量为30至300g/m2的一种微细长丝无纺材料组成，所述的无纺材料是由熔纺的，气动拉伸并且直接铺成纤维网的多组分连续长丝组成，其纤度为1.5至5dtex，必要时在预加固后，多组分连续长丝至少80％被分裂成纤度为0.1至1.0dtex的微细连续长丝并加固。
Description
本发明涉及净化房间清洁织物，它是由单位面积重量为30至300g/m2的一种微丝无纺材料组成。
净化房间在生产，化验和管理精密产品中得到不断广泛的使用，其中重要的是，各种加工步骤要在一种严格无小颗粒的环境中进行。在高技术产品中，如微电子电路，光学或药产品，生产的改善不断对净化房间的颗粒含量提出较高的要求，特别的例子，等级为100净化房间要求在每立方英尺房间空气，尺寸≥0.5μm的微粒在最高100粒的范围内，或在等量的米制净化房间等级M3.54，要求在每立方米的房间空气，尺寸≥0.5μm的微粒不多于3530粒[每百万(百万分之一-ppm)或增多的颗粒每十亿(万亿分之一-ppb)]。集成电路将在所谓的“硅片”上，即薄薄的硅单晶片上生成。集成电路要求三极管和其它的电子器件彼此有精确的电连接。各个电路器件是通过一种由沉积金属组成的导电膜相连接。在这种膜层中，通过一种光刻工艺生产印制导线结构。在下方的半导体元件和沉积的金属膜之间的绝缘层只允许在所设定的位置上有电连接。在“硅片”的表面上涂覆绝缘层，之后制作各器件，但是之前用导电金属沉积“硅片”以制作印制导线结构。污染，如纤维断碎片或灰尘微粒可以导致器件之间的短路，并由此至少使设置的电路功能部分失效。所以在此的基本要求是，所有的表面和工件尽可能地不受到污染。
从文件US4,888,229和US 5,229,181人们熟悉了编织的或针织的清洁织物，通过特殊的边饰滚边它们的边缘防止了细毛露出和纤维断碎片。此外从文件US 4,328,279和5,736,469中人们熟悉了由无纺材料组成的净化房间清洁织物。为了减少可萃取的离子数量或防止静电负荷，在形成无纺材料的纤维表面涂覆一种化学涂层。文件US 5,320,900和US 5,645,916描述了一种净化房间清洁织物，它是由纤维混合物组成的，通过水射流处理无纺材料进行加固。纤维采用合成纤维如聚酯和纤维素-或再生纤维素纤维。这些熟悉的净化房间清洁织物的缺点是，不能经受洗涤过程，然而没有洗涤过程不能达到最高的净化房间等级10或较好的等级。所以这种等级目前只用于编织或针织连续长丝。
本发明的任务是给出物美价廉的、可洗涤的净化房间清洁织物，它满足净化房间等级100的要求，以及生产清洁织物的方法。通过下列净化房间洗涤工艺，根据本发明的，基于微丝纺粘型无纺材料基础上的净化房间清洁织物可以应用在净化房间等级10或更高等级。
根据本发明，用净化房间清洁织物完成任务，净化房间清洁织物是由单位面积重量为30至300g/m2的一种微丝无纺材料组成，所述的无纺材料是由熔纺的，气动拉伸的并直接铺成纤维网的纤度为1.5至5dtex的多组分连续长丝组成，至少80％的多组分连续长丝被分裂成纤度为0.1至1.0dtex的微细连续长丝并加固。这种净化房间清洁织物具有一种表面结构，粉尘微粒和液体很好的渗入到表面结构里，并粘附在其中。此外，由于由连续长丝组成，所以在净化房间清洁织物里只有很少的纤维断头。清洁织物里不含有细毛，清洁织物的边缘也不必翻折缝上或镶边。
优选的净化房间清洁织物是这样的，所述的无纺材料是由熔纺的，气动拉伸并直接铺成纤维网的多组分连续长丝组成，其纤度为2-3dtex，并且至少80％的多组分连续长丝被分裂成纤度为0.1-0.3dtex的微细连续长丝和加固。
优选的净化房间清洁织物是这样的，其多组分连续长丝是由二种彼此不相容的聚合物组成的双组分连续长丝，特别是一种聚酯和一种酰胺。这样的双组分-连续长丝对超微连续长丝有很好的可分裂性，导致一个合理的强度与单位面积重量的比例。
优选的净化房间-清洁织物是这样的，其多组分连续长丝具有桔瓣状或称之为“馅饼状”的多片段结构的截面，其中片段交替地含有二种不相容的聚合物中的一种。除了这种橘瓣状多片段结构的多组分-连续长丝，在多组分连续长丝内不相容的聚合物还可能是并列(s/s)的排列，这有利于产生卷曲长丝。不相容的聚合物在多组分连续长丝内的这种排列证实是有很好的分裂性。
优选的净化房间清洁织物是这样的，至少形成多组分连续长丝的不相容的聚合物中的一个含有一种添加剂，如颜料，永久作用的抗静电剂和/或影响亲水或疏水性能的附加物，最大量为满足在水和异丙醇中允许萃取性值的要求。由纺液染色的长丝组成的净化房间清洁织物有非常好的洗涤稳定性。此外，通过附加物可以降低或防止静电，改善水分传输性能。
据本发明生产净化房间清洁织物的工艺在于，多组分连续长丝由熔体纺丝，气动拉伸，并直接铺成一种纤维网，必要时进行予加固，无纺材料用高压流体射流加固，同时分裂成微细连续长丝，其纤度为0.1至1.0dtex，最好纤度为0.1至0.3dtex。这样获得的净化房间清洁织物密度很均匀，纤维分布均匀，没有分层倾向，表现出高的模数值。
生产净化房间清洁织物最好按下列方法进行，通过用高压水射流对无纺材料的每一面进行多次，至少一次的冲击，使多组分连续长丝进行加固和分裂。由此使净化房间清洁织物具有好的表面，多组连续长丝有＞80％的分裂度。此外，根据本发明的净化房间清洁织物以良好的比吸水性和低的干燥时间而出名。
根据本发明，净化房间清洁织物作为抹拭布可以多次使用。
净化房间清洁织物的优点是满足工业净化房间可洗涤性的要求，可在净化房间等级10或更高等级上得到应用。
