机动车辆内部装饰材料制造工艺及机动车辆内部装饰组件 部件
技术领域
本发明涉及一种制造机动车辆内部装饰材料的工艺，其包括针刺毡或至少实质上由针刺毡组成，所述针刺毡具有纤维混合物，其包括25-35wt％的聚酰胺(PA)纤维和65-75wt％的聚酯(PES)纤维，优选没有其他，优选没有其它，粘合纤维，并通过针刺和通过粘接机械地固结。本发明还涉及一种机动车辆内部装饰组件部件。
背景技术
在机动车辆结构，它是一个良好惯例，以从针刺毡材料制造用于机动车辆内部的内部装饰组件部件或舾装件。这里使用的针刺毡或绒毛毡(pilefelt)，例如针刺毡，是基于由各种制造合成聚合物纤维的混合物组成的纤维网，如聚酰胺(PA)纤维、聚酯(PES)纤维或聚丙烯(PP)纤维。此纤维网接着以常规方式机械地通过针刺和依附地通过黏接固接，选择性地施加道基材上，并且，如果需要的话，经受热成形步骤或加工，以热塑性地模制针刺毡材料到装饰组件部件或舾装件上。但是，关于其可能使用的范围和特别是有关其表面外观，还是需要改善这样的机动车辆内部装饰材料。这特别适用于针刺毡材料通过最终热成形操作而转化成其设想用于进一步使用的最终状态。
纤维网混合物组件部件把包含热塑性纤维和较高融熔加强纤维与至少一薄膜层压体结合起来从WO2004/098879 A1是公知的。纤维网里面例如包括以80:20和20:80之间的混合比例的聚酰胺(PA)热塑性纤维和聚酯(PE)加强纤维。纤维网是通过针刺固结。热成形操作是使用来模制针刺混纺纤维到车用内部部件。
由聚酯粘合纤维和聚酰胺基质纤维组成的和使用在用于机动车辆的内部舾装的模制部件的生产的纤维网也从DE10007556 A1是公知的。本文中公开的针刺毡具有10:90至90:10的混合范围中的聚酰胺纤维到聚酯纤维的混合比例，且还具有包含20至100针距/平方公分的针聚密度的针刺毡。此外，聚酯粘合纤维以卷曲状态和具有纤维线性密度或1.7至17分特(dtex)的纤度进行处理。
用于制造机动车辆的底板部件的针刺毡进一步从DE 36 25 473 A1是公知的。此针刺毡可以由具有约15至20dtex的纤度的聚酰胺和聚酯纤维的混合物组成，优选为17dtex，以及以100至250针距/平方公分的针距密度被侦测到针刺毡。此针刺毡被模制到底板部件中。
DE 101 64 087 A1公开一种装饰性非织物以400至1000针距/平方公分的针距密度通过纤维的针刺形成为针刺毡，以及其在它的绒毛侧具有1至6mm的绒毛高度或纤维高度。
机动车辆的内部部件从DE 11 2012 005 205 B5是附加地公知的。此内部部件包括作为一层且由其中可以包括聚酰胺纤维或聚酯纤维的针刺纤维网和中空纤维组成的地毯层。此针刺毡接着与其他分层成分一起模制为内部部件。
发明内容
本发明提出的问题是因此提供一种提供针刺毡材料的解决方法，特别是机动车辆内部装饰材料，其具有视觉吸引力表面加工，即使在150℃和250℃之间的温度范围的热成形之后。
上述问题是通过根据本发明实施方式的一种机动车辆内部装饰材料和一种机动车辆内部装饰组件部件来解决。
机动车辆内部装饰材料和机动车辆内部装饰组件部件不仅意旨这样的材料和这样的组件部件是合适的，而且打算用于机动车辆的内部空间的使用。
通过根据本发明的工艺得到的机动车辆内部装饰材料是因此首先根据本发明被特征在于，针刺毡的纤维部分由包含从25至35wt％的聚酰胺(PA)纤维和从65至75wt％的聚酯(PES)纤维的纤维混合物组成。惊人地，由25wt％的聚酰胺(PA)纤维和从65至75wt％的聚酯(PES)纤维组成的纤维混合物的使用和部署具有的效果是，热成形加工和操作通常在约200℃的温度范围被执行，随后制造和加工这类机动车辆内部装饰材料，或在它的进一步加工成机动车辆内部装饰组件部件的过程中，不会阻止表面纹理和表面外观的此后程度，其是是非常有吸引力的且代表在这种类型的直到此时公知的表面处理上的明显改善。用于此的理由是聚酰胺纤维部分的混合，优选地没有进一步或其他的粘合纤维。聚酰胺纤维确保针刺毡的纤维在热成形操作后回到它的直立位置。聚酰胺纤维在这种热形成步骤或热形成操作后还防止残留光泽的表面。包含本发明的针刺毡的机动车辆内部装饰材料或机动车辆内部装饰组件部件的纤维侧表面范围的所需纺织外观甚至在这种热成形处理之后建立的。通过本发明提供的25-35wt％的聚酰胺纤维的部分已被证明是最佳范围。另一方面，为了获得用于材料制造的适当强度、适当粘合和廉价的生产整体，它另外被证明是有利的以包括在纤维混合物中除聚酰胺纤维外的从65至75％wt％的聚酯(PES)纤维。
如上所述的相同优点也是通过提议以解决上述问题的机动车辆内部装饰组件部件来拥有，且通过对根据本发明的机动车辆内部装饰材料进行热成形来得到，优选在150℃至250℃的温度范围。以实现针刺毡的热塑性、选择性地甚至热固性、变形的这类热成形操作通常在约200℃的温度范围下进行。
特别有利的是，用于针刺毡的纤维混合物由30wt％的聚酰胺(PA)纤维和70wt％的聚酯(PES)纤维组成。
本发明进一步提供的是，针刺毡是由纤维网形成，且纤维网具有25至35wt％的聚酰胺(PA)纤维和65至75wt％的聚酯(PES)纤维的部分，且针刺毡通过针刺和还通过黏接机械地固接。这种类型的纤维网，其中针刺毡接着通过针刺和结合或黏接，对于制造本发明的机动车辆内部装饰材料是特别有用的。正是在这样的连接，然后用于本发明的目的重要的是，以形成针刺毡和以发展有利表面外关，棉絮被铺设从纤维混合物连续通过三个针刺机，所述三个针刺机各自在垂直方向具有或执行针刺运动，其中首先在第一针刺机中，所述棉絮的前针刺或预先针刺以35和150针距/平方公分之间的针距密度被实现，特别是76针距/平方公分，之后在第二针刺机中，返回针刺以50和300针距/平方公分之间的针距密度被实现，特别是110针距/平方公分，及最后在第三或最后类型针刺机中，针刺毡以500和1000针距/平分公分的针距密度被制造，特别是860-900针距/平分公分，更优选为880针距/平分公分。在此剪切操作的过程中，从铺网机出现的紧密的棉絮最初地穿过第一针刺机，其中的针以针刺方向垂直向下贯穿棉絮以实现预先针刺。返回针刺接着发生在随后的第二针刺机，使得之后针刺毡的穿透在越过第一和第二针刺机后的针刺毡的两侧已经实现。因此，如本文使用的预先针刺和返回针刺的术语也应被理解成意指的是针刺首先从前侧(前针刺)且接着从棉絮的于此相反侧(返回针刺)，或通过接着先前纤维网来实现。此措施导致纤维缠结的同质化和均匀程度的发展，其导致的表面一致性的优异标准和耐磨性的高层次。通过第三针刺机或最后类型针刺机，纤维网接着最后地通过以接着实现针刺的最终型式，其是优选地再次实现成来自前侧的前针刺。然而，如果需要，这种针刺的形式也可以实现成来自依靠在三个针刺机的纤维网路径的面侧的返回针刺，且两侧的返回针刺是以后成为具有所需正面外观的装饰表面具有所需正面外观。在所有三个针刺操作，即所有三个针刺机，所有针刺完全地贯穿非织物。
剪切在它的绒毛侧上的所制造的针刺毡的步骤不仅给予在纤维绒毛端部的均匀长度，而且在同一时间，使得纤维绒毛端部在此剪切或切割操作的过程中以垂直方向站起来。
施加水性粘合剂以带来关于粘接的步骤带来关于纤维的粘合固接和集成，使得它能够达成高耐磨强度和纤维锚固力。这包括在运行中的牢固性的高质量。
用于制造根据本发明实施例的机动车辆内部装饰材料是特别有利的，当纤维混合物是由具有4.4-17dtex的纤度的聚酰胺纤维和聚酯纤维形成，特别是5.6-7dtex的纤度。以这样的纤度使用聚酯纤维和聚酰胺纤维将在其本身导致在其他的或额外的粘合纤维或粘合线的纤维混合物的混合的针刺处理的过程中的纤维网及/或针刺毡的这类强度和固结可以被避免。
这里特别有利的是，当纤维混合物被形成具有2.5-4.5弧/公分(arcs/cm)的卷曲和4.4-7dtex的纤度的卷曲聚酰胺纤维，特别是3.5弧/公分和特别是5.6-7dtex的纤度，如在本发明的修饰中提供。在聚酰胺纤维的棉絮或针刺毡纤维混合物从而卷曲和具有这种纤度的原因的使用，首先，针刺加工是在其本身足以保证网的充分固结。然而，更特别地，这样聚酰胺纤维的使用导致这些卷曲和细的聚酰胺纤维，在通过热成形操作后，能够快速重新采用垂直取向，从而提供针刺毡的表面方面的期望特别良好的外观。
在特别有利的方式中，为了以剪切操作达成绒毛纤维及/或纤维绒毛端部的扶正，有利的是以剪接机的旋转剪切缸来进行剪切。因此，在本发明的进一步的发展中，针刺毡的绒毛侧是使用剪切机的一个或多个旋转叶片缸来剪切。
在用于机动车辆内部装饰材料及/或由其制造的车辆内部装饰组件部件的表面方面的期望改善外观的有利发展中，在针刺毡的绒毛侧上的纤维是使用剪切装置的一个或多个旋转叶片缸剪切或切割至1.5mm-3mm的长度或绒毛高度，其又是本发明的有利实施例。这保证的是直立纤维绒毛的定义比例通过旋转叶片剪切/切割至定义高度，且通过旋转缸的叶片的旋转运动来均质化。在剪切操作中，纤维绒毛端部被切断，且随后切断纤维的端部是垂直竖立。
特别有利的是使用水性粘合剂，其包括来自苯乙烯-丁二烯橡胶、苯乙烯-丙烯酸酯、丙烯酸酯的聚合物或羧基化苯乙烯-丙烯酸酯的混合物。因此，在本发明的进一步修饰，水性黏合剂，特别是水性分散液，是以最小泡沫附加加工施加到剪切的毛针毡的远离剪切绒毛侧的那侧，且在随后的步骤干燥，以形成带来关于黏接的粘合剂膜。
以有利的方式来施加水性粘合剂，剪切的针刺毡以泡沫最小附加加工(例如以辊舐加工)涂覆在相对于具有水性分散液的推穿绒毛的侧上，且随后干燥而在同一时间形成带来关于黏接的膜。因此，在进一步的发展中，本发明还提供水性粘合剂，特别是水性分散液，是以最小泡沫附加加工施加到剪切的毛针毡的远离剪切绒毛侧的那侧，且在随后的步骤干燥，以形成带来关于黏接的粘合剂膜。
制造机动车辆内部装置材料的工艺可接着还额外地提供对所得到的针刺毡热形成的步骤。
有特殊用途的情况，但选择性地也只是准备所需的热成形操作的实行，其中可能是有利的施加针次毡到基材。因此，本发明最后也限定的是，针刺毡已经施加到基材上。
本发明最后提供的是在烘干水性黏合剂之后或在施加针刺毡于基材上之后，针刺毡被热形成，这已经被证明是特别有利的时机。
附图说明
本发明的说明性实施例现在将通过举例的方式更具体地描述。从而，
图1示出棉絮穿过如关于传输的方向上的以串连方式连接的三个针刺机的示意图。
具体实施方式
本发明的机动车辆内部装饰材料且也是机动车辆组件部件的制造，使用相同设备及如迄今常用于这种类型的针刺毡材料的相同处理步骤而实质上实现。非常同质混合物由纤维混合物制备，其中纤维混和物由来自25至35wt％，优选为30wt％，的聚酰胺(PA)纤维和来自65至75wt％，优选为70wt％，的聚酯(PES)纤维组成。在说明性实施例中，聚酰胺纤维和聚酯纤维具有5.6至7dtex的纤度，且聚酰胺纤维还具有3.5弧/厘米(arcs/cm)的卷曲。棉絮是以常规方式从此纤维混合物来制造，即通过铺设在铺网机中。从铺网机出现，紧密的棉絮仅仅描绘如图1中的箭头，且在此被称为1，其被传送至称为整体如2的针刺装置。棉絮1接着以箭头1的方向穿过此针刺装置2，最初的通过第一针刺机3，之后通过第二针刺机4且最后通过第三针刺机5。从第三针刺机5出现的产品是已经被针刺的针刺毡，如接着通过标出具有参考符号6的箭头而表示于图1中。棉絮1是最初被传送到第一针刺机3，其中它通过针被垂直向下移动而从上面贯穿来前针刺或预先针刺。在此第一针刺机3中，说明性实施例的棉絮1以76针距/平方公分的针距密度被冲压。从第一针刺机3出现，棉絮1被引导在多个方向转换辊7上，使得棉絮1接着以面向第二针刺机4的针刺侧8的那侧前进，其中面向第二针刺机4的针刺侧8的那侧在第一针刺机3中是棉絮1面向远离其针刺侧8的那侧。在说明性实施例中，第二针刺机4接着以110针距/平方公分的针距密度从棉絮1的背面侧实现返回针刺。在所有三个针刺机3至5的针刺全部完全的贯穿棉絮1，且因此甚至如它从第二针刺机4出现，在此点将已经是第一针刺毡的棉絮1实际上已经显示出互相贯通，其导致用于准备被针刺的针刺毡6的均匀一致性表面方面和用于耐磨性被达成的基础的纤维的同质化和均匀纠缠。在从第二针刺机4出现之后，棉絮1或已经形成的第一针刺毡最后穿过第三或最后类型针刺机5，其中在第三针刺机5中，棉絮1或第一针刺毡再次以如在第二针刺机4中的相同取向进行针刺。即，棉絮1的相同表面侧面如在第二针刺机4中面向在第三针刺机5中的针刺侧8。如在第一针刺机3和第二针刺机4，垂直排列的针同样地以说明性实施例于此的880针距/平分公分的针距密度垂直向下穿过第三针刺机5的棉絮1。在此最后类型针刺机5中，纤维的垂直排列被表明和放大，并且也制造密集和稳定的绒毛。所以，针刺毡6已经通过针刺从棉絮来制造。针刺毡6接着被传送以在后续阶段和加工步骤中制造机动车辆内部装饰材料，以箭头方向接在针刺装置2后首先到剪切装置和之后到粘合剂施加器装置。在剪切装置中，针刺毡6在它的绒毛侧上被剪切。说明性实施例通过包括装配有至少一剪切叶片的至少一旋转缸(叶片缸)的剪切机来进行剪切，以在针刺毡6的绒毛侧上将纤维剪切或切割到1.5至3mm的长度或绒毛高度，在说明性实施例中到2mm的绒毛高度。在这种情况下，从垂直竖立纤维绒毛被切断的区域通过旋转叶片(多个旋转叶片)被切割下降到2mm的所需绒毛高度。在此工艺中，纤维绒毛通过旋转叶片(多个旋转叶片)被同质化，即均匀化，而在同一时间，在剪切或切割操作的过程中，纤维绒毛端部被切断，且直立放置的切割纤维端部被制作成竖立起来。
在剪切之后，被剪切的针刺毡被发送到粘合剂施加器装置，由此水性分散液在被剪切的针刺毡的背面侧提供给被剪切的针刺毡，即被推动绒毛相反的一侧。水性分散液包括水性粘合剂，其包括来自苯乙烯-丁二烯橡胶、苯乙烯-丙烯酸酯、丙烯酸酯的群的聚合物或羧化苯乙烯-丙烯酸酯的混合物。此水性黏合剂或分散液是以最小泡沫附加加工施加到所述剪切的针刺毡的远离剪切绒毛侧的那侧，且在随后的步骤进行干燥，以形成带来关于黏接的粘合剂膜。通过黏接的黏合固结对于纤维锚固是非常重要的，由于高耐磨性和纤维锚固力是可达到的，从而其包括在运行中牢固性的高质量。
以由此形成的棉絮1的形式的纤维混合物经受在其中通过针刺而机械地固结的连续操作。这些加工步骤的至少一个被配置，使得绒毛毡在针刺的过程中被形成。除了机械地固结，纤维混合物经受粘合固结，即粘合效果。为此，相应合适的粘合剂在导致针刺毡的制造操作的过程中被混合到纤维混合物。包括针刺的加工步骤也包括针刺操作或加工步骤的完成类型，其中纤维混合物使用500至1000针距/cm2的针距密度来针刺，优选为860至900针距/cm2，特别是880针距/cm2。在最后针刺类型加工步骤之后，所得到的具有特别地形成为绒毛毡的表面的针刺毡被剪切修整回到均匀纤维长度，特别地在剪切后到1.5mm至3mm之间的绒毛高度。
之后，这样得到的针刺毡是经受热成形工艺或操作，特别是在150℃和250℃之间的温度范围中的惯例热塑性模制，优选约200℃。这里可以额外提供的是，在通过热成形操作之前，纤维网材料以常规和公知的方式被施加在基材上，因此针刺毡一起与基材经历模制。在通过此热成形操作之后，所得到的针刺毡构成其也可以选择地构成机动车辆内部装饰组件部件的机动车辆内部装饰材料，除非它仍经受一个或多个进一步且随后的处理步骤和选择地已经所需的大小制造。
本发明的针刺毡及/或机动车辆内部装饰材料的制造有利地利用具有5.6至7dtex的纤度的聚酰胺纤维，特别是6.7dtex分特的纤度。
