Abstract

在用于生产非织造织物(12)、结构或制品的装置中，组合使用非织造法和含有导电材料(22)的传送带(18)，以消散静电荷同时保持理想的透气性。

Description

用于非织造工艺的防静电传送带
技术领域
本发明涉及非织造织物的生产及其相关的问题，尤其涉及与之相关的气流和静电。
背景技术
目前存在用于生产非织造织物的装置，所述非织造织物例如由通常从热塑性树脂制成的长丝或纤维形成的纺粘的织物、结构或制品。1998年9月29日授权的美国专利No.5,814,349中公开了这种装置，其公开内容引入本文作为参考。这些通常包括用于产生丝束帘的喷丝头和用于将工艺空气鼓吹到该丝束帘上的工艺鼓风机来冷却该丝束帘以形成热塑性长丝。然后，通过气动拉伸热塑性长丝的工艺空气典型地、气动地输送该热塑性长丝，经过扩散器后，该热塑性长丝沉积在连续循环的带式筛网上来收集互相缠结的长丝并在那里形成织物。然后，传送由此形成的织物、结构或制品并进行进一步加工。
上述类型的装置，尤其是用于高速热熔粘合织物生产的装置，目前可以得自
Figure GSB00000139138800011
GmbH Co.Maschinenfabrik，Spicher StrabeD-53839Troisdort，德国并且以商品名
Figure GSB00000139138800012
出售。最新代的这种高速纺粘生产线称作3型系统。
这种设备的另一个生产商是Nordson Corporation，28601Clemens Road，Westlake，Ohio 44145。另外的生产商是STP Impianti，Rieter Perfojet，Kobelco，Ason和NWT。
还可以使用气流成网法形成非织造织物。该气流成网法以脱纤维系统开始来打开短纤浆。传统的成纤器或其它的粉碎设备也可用于形成分离的纤维。然后，吸收材料粒子(例如超吸收粉末)、研磨剂或其它材料可以和纤维混合。然后该混合物悬浮在形成系统内的气流中并沉积到移动的成型网、筛网或旋转的多孔滚筒上。然后，可以通过应用胶乳粘合剂并干燥、热粘合织物中的热塑性短纤维、氢或压花粘合或其组合来粘合无规取向的空气形成的纤维。
此外，在上述的粘合步骤前可以任意地压紧非织造织物。典型地在粘合前在成型网上进行压紧。在压紧过程中，和纤维混合的吸收剂、研磨剂或其它材料损害成型网。
在压紧步骤中在该位置可以使用毡来防止对成型网的损害。毡的可压缩性使得在不损害该毡或成型网的情况下，压紧非织造织物。
存在大量的商业化工艺来生产气流成网的非织造织物。例如，气流成网工艺可以从在Risskov，Denmark具有办事处的Dan-Web公司，和从在Horsens，Denmark具有办事处的M&J Forming Technologies购买。
本发明涉及非织造织物的生产及其相关问题，尤其涉及静电。
在非织造工艺中，产生大量的静电。本发明解决该问题。通常，在加工时在长丝或纤维上形成负电荷。由于具有相同的极性，纤维的连续层易于互相排斥。带电荷的纤维易于粘附压辊。由于在带电荷的纤维的加工中形成电荷，所以带电荷的纤维还易于被成型织物排斥。该电荷易于累积。
欧洲专利申请No.EP 950744 A1中，建议使用具有介电表面的压辊，所述的介电表面具有与纤维排斥的极性。成型织物还可以由介电材料制成并具有与纤维的电荷相反的电荷，从而将纤维吸引到其上。
本发明涉及消散静电荷同时保持传送带的透气性。迄今，美国专利4,427,736建议消散较干燥织物形成的静电荷，由此防止当纸从一个织物上传送到另外一个织物上时纸粘附到织物上。
美国专利4,541,895是由大量不透性的非织造片以层合排列的方式连接在一起形成的PM织物。每层用作特定的目的，例如抗静电荷。此外，可以在层之间引入纱线以增加抗静电性能。
美国专利6,001,749提供了通过在织物的选择性部分应用表面涂料的提花导电纺织品，所述织物的选择性部分抑制了导电聚合物涂层在那些区域的形成。
美国专利6,153,124是由2到30％重量的导体纱线制成的导电针织织物。该导体纱线由5到30％重量的电镀铁纤维和70到95％重量的聚酯纤维制成。导电率与纱线的浓度成比例。
然而，没有任何一个现有技术提供一种抗静电传送带用于生产具有织造或螺旋形成的基底的非织造物，其中向所述基底上添加导电棉絮、泡沫或其它材料，同时保持所需的透气性。
发明内容
因此，本发明的主要目的是提供用于生产非织造织物、结构或制品的传送带，所述传送带消散静电荷。
本发明的另一个目的是保持抗静电传送带的充分的透气性。
本发明实现了这些和另外的目的和优点。在此方面，本发明一般性地涉及用于生产非织造织物、结构或制品的传送带。为了解决静电问题，该传送带可以包含导电材料，所述导电材料能消散织物上的静电荷同时保持该带所需的渗透性。
本发明的一个实施方案提供一种工业防静电传送带，其包含：由纱线形成的基础基底；施加到所述基底的导电材料；所述带能够消散静电荷同时保持20～200CFM的所需透气性，其中所述导电材料是导电棉絮或导电泡沫；其中所述带用于装置中以生产非织造织物，所述非织造织物由选自气流成网法、干法成网法、纺粘法、熔喷法、水刺法或上述生产工艺中两种或多种的组合形成。
附图说明
因此，通过本发明的详细说明并结合附图，将了解其目的和优点。其中：
图1是其中传送非织造织物、结构或制品的装置的示意图；和
图2是沿该带的机器方向放大的本发明的传送带的剖面图。
具体实施方式
现在更具体地说明附图，其中相似的元件具有相似的附图标记，图1示意性显示通过织造以外的工艺，例如，通过气流成网法、干法成网法或水刺法生产非织造织物12的装置10的一部分。在处理之前将织物12从第一个位置14传送到第二个位置16的的过程中，在织物12和传送带18上产生大量的静电荷，所述静电荷是不希望的。关于此，需要传送带18可渗透真空系统19抽吸的空气以辅助织物12的传送。
有利地，本发明是在非织造工艺中使用的传送带，所述的传送带消散静电荷同时保持所需的透气性。关于此，显示在图2中的是用于本发明的抗静电传送带18的横断面。该传送带18包括由织造或螺旋的聚合物材料(其本身可以是导电的)制成或由其它适于覆盖以导电棉絮、泡沫或其它材料22的结构制成的基础基底或结构20，当该带被涂敷时，能保持透气性在约20～200CFM或更高，同时具有在100欧姆/平方～108欧姆/平方的低电阻系数。
基础基底可以是用作造纸机织物基底的结构中的任何一种，例如织造或螺旋连接的织物。该基础基底还可以由以多个捻度螺旋缠绕的织造材料之一的条带组成，其中每个捻度通过连续的接缝与邻近的那些连接，其公开于共同转让给Rexfelt等人的美国专利No.5,360,656，其教导引入本发明作为参考。另外，所述基础基底可以是环状编织的，或是平坦的织物并随后用织造接缝形成环状。
该基础基底还可以是含有两层或多层基础基底的层合结构；每层可以是上述结构中的一种。在层合基础基底时，组成的基础基底中的一种可以是可机械缝合的(on-machine-seamable)织物，使得该带可以在安装在造纸机上时被缝合成环状形式。
基础基底可以由生产造纸机织物和工业加工织物的任何纱线织造或以其它方式组合，也就是说，基础基底可以包括单丝、合股单丝、复丝、合股复丝或本领域技术人员使用的任何合成聚合物树脂的人造纤维纺成的纱线。
在图2所示的实施例中，基底20赋予带18以尺寸稳定性和可压缩性；导电棉絮、泡沫或其它材料22通过带18将织物12的静电消散到地面。注意基底20可以通过针刺、热粘合、缝合、化学工艺或其它适用于该目的的方法连接到棉絮、泡沫或其它材料22上。
此外，可以将导电材料22涂敷在基础基底或结构20上。涂敷的导电材料22可以通过喷涂、挤压或作为热熔性材料层施加于基础基底或结构20上。
作为另外的优点，棉絮、泡沫或其它材料22的织物接触面是平滑的，以避免某些非织造织物生产相关的阻塞(plugging)和疵点(marking)问题，其中所述非织造织物的生产使用大量的通常被称为超吸收性粉末或SAP的物质。例如，可以通过压紧或砂磨处理涂敷的导电材料22的表面得到理想的表面形态或光滑度。
因此，本发明的抗静电传送带18是多层结构的，其可以包含一个或多个基底20和一层或多层棉絮、泡沫或其它材料22，其一部分是导电性的。该传送带18在非织造物生产中减少静电荷同时在织物生产过程中提供理想的透气性。
虽然本文中详细公开并描述了优选的实施方案，但是其范围不应限于此，其范围应该由所附的权利要求决定。
