Description

用于维可牢搭扣的构成圈的搭扣元件以及用于制造搭扣元件 的方法
技术领域
本发明涉及一种用于维可牢搭扣(velcro fastener)的构成圈的搭扣元件，该搭扣元件包含压花的无纺布材料，该无纺布材料具有纺粘型无纺布长纤维和梳理过的短纤维。此外，本发明的技术方案还包括一种用于制造维可牢搭扣的这种搭扣元件的方法。
背景技术
构成圈的搭扣元件是维可牢搭扣的阴性部件。搭扣元件尤其是应用作用于一次性卫生用品、如纸尿裤或失禁垫的低成本产品。
在使用纸尿裤时，条带形式的构成圈的搭扣元件设置在纸尿裤的前侧的滚边区域上。借助固定在纸尿裤侧面的并且在其自由端部上具有纠缠钩的搭扣带补全维可牢搭扣。由于在使用时纠缠钩贴靠在构成圈的搭扣元件上并且在那里钩住，所以构成圈的搭扣元件又称为“着陆区”(Landing Zone)。
维可牢搭扣可重复打开和封闭，且不由此损坏搭扣的功能。与胶粘剂搭扣相反，维可牢搭扣相对于与护肤霜或扑粉的接触不敏感。
对于一次性产品上的维可牢搭扣提出多种要求。首先，维可牢搭扣的构成圈的搭扣元件出于成本原因应尽可能简单地借助尽可能少的材料来制造。此外，构成圈的搭扣元件必须确保与相配的搭扣带的纠缠钩充分地钩住。最后，搭扣元件也应具有吸引人的设计并且具有舒适的触感。
DE 20 2004 021 382 U1公开了一种构成圈的搭扣元件，该搭扣元件在载体膜上具有针织物，该针织物和载体膜通过胶粘剂图案彼此连接。针织物例如具有18g/m2的单位面积重量，从而总体上实现轻的开口式结构，在此也可透过针织物看到载体膜上的装饰印样。通过图案状地涂敷胶粘剂可实现在无胶粘剂的区域中圈不粘接并且可被纠缠钩自由接近，在此纠缠钩甚至可嵌入针织物的基础结构中。相反，在粘接的区段上可设置如此多的胶粘剂，以致针织物可靠固定。在此必须忍受各个圈一同被粘接到胶粘剂中。
具有针织的圈的构成圈的搭扣元件已在实践中被证明有效，但触感有时被认为是不舒服的。即使构成圈的搭扣元件仅在例外情况下直接与使用者接触，但仍然需要为各种应用改进材料的皮肤友好性。
除了具有针织的圈的搭扣元件外，还已知无纺布材料，其构成适合用于与纠缠钩连接的圈。
由EP 0 963 472 B1已知一种用于维可牢搭扣的构成圈的无纺布，在此为了产生足够牢固的结构使用双组分纤维。为了在纤维之间实现多种组织，在热空气下熔化双组分纤维的一种聚合物组分。制造方法总体上是复杂的。
由WO 03/105621 A1公开了一种水刺无纺布作为构成圈的搭扣元件，所述圈通过水射流(水刺)加固形成。为装饰目的无纺布设有压花。已知的无纺布的表面特性和纠缠效果仍需改进。
DE 10 2004 053 469 A1公开了一种具有开头所描述的特征的构成圈的搭扣元件，其中在无纺布上设置分梳绒、即由梳理过的短纤维构成的层并且如此形成的无纺布材料设有压花。分梳绒和无纺布设置用于不同目的。梳理过的短纤维设置用于与纠缠钩连接，而无纺布的长纤维则实现高的稳定性和在载体膜上的固定。
EP 0 937 420 A2公开了一种用于维可牢搭扣的构成圈的搭扣元件，该搭扣元件可包含具有纺粘型无纺布长纤维和梳理过的短纤维的无纺布材料。为了构成圈，描述了一种机械针刺法。
发明内容
在此背景下，本发明所基于的任务在于提供一种用于维可牢搭扣的构成圈的搭扣元件，该搭扣元件包括压花的无纺布材料，该无纺布材料的特征在于特别有利的机械特性、良好的纠缠效果以及特别软的表面。此外，还应提出一种用于制造这种搭扣元件的方法。
本发明的技术方案和该任务的解决方案是根据本发明的构成圈的搭扣元件以及根据本发明的用于制造这种搭扣元件的方法。根据本发明的用于维可牢搭扣的构成圈的搭扣元件包含压花的无纺布材料，该无纺布材料具有纺粘型无纺布的长纤维和梳理过的短纤维；所述长纤维和短纤维彼此缠绕并且共同构成一个由纤维混合物制成的无纺布层，并且长纤维的含量相对于短纤维的含量在无纺布层的厚度上变化，并且在无纺布层的两侧上短纤维突出。在根据本发明的用于制造根据本发明的搭扣元件的方法中，通过挤出和沉积长纤维形成纺粘型无纺布，接着在纺粘型无纺布上这样铺放由梳理过的短纤维构成的层，使得短纤维位于如此形成的无纺布材料的第一侧上，借助液体射流加载无纺布材料的长纤维和短纤维并且由此使长纤维和短纤维彼此混合和缠绕，对无纺布材料进行冷压花。
从具有开头所描述的特征的构成圈的搭扣元件出发，根据本发明所述任务以下述方式来解决：所述长纤维和短纤维彼此缠绕并且共同构成一个由纤维混合物制成的无纺布层。根据本发明，如此以特别有利的方式彼此结合了长纤维和短纤维的特点。长纤维构成连续的稳定结构，该结构也允许在材料之内传递拉力。又称为短绒的短纤维相反形成特别软且起绒的结构，在此至少一些短纤维在无纺布层的两侧上突出。
通过缠绕和混合长纤维以及短纤维，首先将短纤维有效地锚固于无纺布材料中。长纤维大致构成基础结构，短纤维被混入该基础结构中。
通过纤维彼此间的混合和缠绕——这例如可通过加载水射流(水刺)实现，短纤维和长纤维都可以在无纺布材料的表面上构成圈，这些圈适合用于容纳纠缠钩。
根据本发明对整个无纺布材料进行压花。通过压花首先提高了无纺布材料的稳定性和强度。在压花区域之间短纤维及长纤维可特别强地通过水射流鼓起，从而改善了纠缠效果。此外，通过压花也可增大无纺布材料的表面，并且恰恰在压花的边缘上纠缠钩可深深嵌入无纺布材料中。
根据本发明的一种优选方案，压花的无纺布材料完全由长纤维和短纤维构成，因此无纺布材料仅由一个由纤维混合物制成的无纺布层构成。
在制造构成圈的搭扣元件时，无纺布和梳理过的短纤维通常作为分开的层被供应并且随后例如通过水刺彼此缠绕和混合。在这种操作方法中，通常不进行完全均匀的混合，因此长纤维的含量相对于短纤维的含量在无纺布层的厚度上变化，在此至少这样进行缠绕和混合，使得在无纺布层的两侧上至少一些短纤维突出。通常，短纤维在无纺布材料的最初被供应短纤维的一侧上含量更大。该侧在通过水刺的混合和缠绕后也更软并且优选用作搭扣元件的用于与纠缠钩连接的露出侧。
这样构造无纺布层，使得该无纺布层在常见的纠缠钩的情况下具有足够的抗拉强度和足够的自由圈。另一方面，仅出于成本原因追求尽可能小的单位面积重量，并且在无纺布材料下方也可设置装饰印样，其应能透过无纺布层被看到。在此背景下，无纺布层的单位面积重量优选在20g/m2和50g/m2(克每平方米)之间。具有所给出的单位面积重量的无纺布也称为蓬松无纺布。
为了使搭扣元件易于固定在卫生用品、如纸尿裤或类似物上并且能够被设置装饰涂层，可将无纺布材料与载体膜粘合。粘合在此可通过具有粘合区段和无胶粘剂面的胶粘剂图案实现。适合的胶粘剂图案由DE 20 2004 021 382 U1公开。尤其是可设置由聚烯烃制成的单膜作为载体膜。
优选载体膜具有10μm和40μm之间的厚度，例如可使用由聚乙烯制成的单膜，其特别优选在与无纺布材料粘合前被设置印样。作为胶粘剂例如可设置单组分聚氨酯胶粘剂。
如上所述，压花有利于提高强度并且也有利于改善纠缠效果。但在此应考虑，压花区域不能或只能以较低的程度用于与纠缠钩连接。在此背景下，压花的面积份额优先在5％和20％之间。
无纺布的密度例如可在0.04g/cm3和0.1g/cm3之间。
长纤维通常无定向地沉积并且可具有0.8至1.8分特、优选1.0至1.2分特的细度。
短纤维可以是卷曲的并且例如具有2.2至15分特、优选4至10分特的细度。
原则上也可规定两种不同类型的具有不同细度的短纤维。尤其是可设置细度较小的如1.2至2.1分特的第二类型。第一类型相对于第二类型的比值优选大于1:4。
原则上各不同的印花图案是适合的。除了点状和网格状的压花外，无纺布材料尤其是也可设置线状或波纹状的压花。尤其是也可在中断的波纹形状中产生视觉上吸引人的外观，该外观也可与位于下方的印样协调一致。
为了总体上实现低的制造成本，长纤维优选由聚烯烃制成，在此尤其是聚丙烯适合用作长纤维的材料。短纤维也可由聚烯烃、尤其是由聚丙烯(PP)制成，于是也可提供类型纯一的无纺布材料。此外，聚酯、尤其是聚对苯二甲酸乙二醇酯(PET)也适合用作短纤维的聚合物材料。
优选在制造时首先被铺放短纤维的一侧上形成压花并且该侧也优选设置用于与纠缠钩连接。
本发明的技术方案还包括一种用于制造所描述的搭扣元件的方法，其中，通过挤出和沉积长纤维形成纺粘型无纺布，接着，在纺粘型无纺布上这样铺放由梳理过的短纤维构成的层，使得短纤维位于如此形成的无纺布材料的第一侧上，接着借助水射流(即水刺)加载无纺布材料的长纤维和短纤维并且由此使它们彼此混合和缠绕，并且对无纺布材料进行冷压花。在制造方法中结合压花和加载水刺，并且为了压花和加载水刺将无纺布以及由梳理过的短纤维构成的层供应到两个辊之间的辊隙，在此至少一个所述辊具有压花结构和用于产生水刺的包括大量开口的穿孔结构。当无纺布材料在压花结构的突起上被保持和固定在辊隙中时，其余区域露出，因此可在那里使纤维彼此紧密混合并且鼓起。
尤其是辊可具有用于产生水刺的包括大量开口的穿孔结构。穿孔结构的开口在此可设置在压花结构的突起之间。
为了实现纤维的良好缠绕，也可相继设置多个辊对。
如上所述，无纺布材料在冷压花和加载水刺之后可借助胶粘剂粘合到之前被印上装饰的载体膜上。与该膜的粘合优选在无纺布材料的第二侧上、即与第一侧相对置地进行，在第一侧上之前已在纺粘型无纺布上铺放短纤维层。
附图说明
下面参考仅示出一种实施例的附图详细说明本发明。附图如下：
图1为用于维可牢搭扣的构成圈的搭扣元件；
图2和3为用于制造在图1中所示的构成圈的搭扣元件的方法步骤；
图4为在根据图2的方法中所使用的辊的表面上的压花结构；
图5为用于将无纺布材料和载体膜粘合的胶粘剂图案。
具体实施方式
图1示出一种构成圈的搭扣元件，该搭扣元件构成维可牢搭扣的阴性部件，所述圈构造用于与无纺布材料1的纠缠钩连接。无纺布材料1在第一侧上具有压花2并且由纺粘型无纺布的长纤维3和梳理过的短纤维4形式的短绒构成。长纤维3和短纤维4彼此缠绕并且构成一个共同的由纤维混合物制成的无纺布层。长纤维3确保无纺布材料1的良好稳定性和强度，而短纤维4实现了特别软的表面。
由图1可见，短纤维4延伸于无纺布材料1的整个厚度上，但在无纺布材料1的设有压花2的第一侧上的短纤维的含量由制造决定略高。
无纺布材料1通过胶粘剂5与单层的载体膜6粘合。
在压花2之间长纤维3以及短纤维4在无纺布材料1的第一侧上——部分构成圈地——突出并且因此可用于与纠缠钩连接，在此不仅可在长纤维3上而且也可在短纤维4上钩住。恰恰在压花2的边缘上纠缠钩可深深嵌入无纺布材料1中。此外，压花2促成无纺布材料1的稳定性。
在压花2上长纤维3和短纤维4在不熔化的情况下彼此变形。无纺布材料1的单位面积重量优选可在20g/m2和50g/m2之间。
如下面详细所述，压花2借助辊7制出。设置用于压花的辊7的表面结构在图4中示出。所示的结构因此也相应于俯视图中的无纺布材料1的压花结构。可以看出，在俯视图中压花2相应于辊的突起8被成形为波纹状区段的形式。压花的面积份额通常在5％和20％之间。
不仅长纤维3而且短纤维4可由聚烯烃、尤其是由聚丙烯(PP)制成。此外，可为短纤维4使用聚酯、尤其是PET作为替代材料。
图2示出用于制造无纺布材料1的步骤，其中，首先从挤出机9挤出长纤维3并且将其沉积用于形成纺粘型无纺布10。沉积的长纤维3在此在尚未完全时效硬化的状态中被引导通过辊隙11并且由此在较低的程度上彼此连接。
接下来，由梳理装置12制造一个由被梳理过的短纤维4构成的层13并且将其这样铺放到纺粘型无纺布10上，使得短纤维4位于如此形成的无纺布材料1的第一侧上。
之后，在此时刻还是两层的无纺布材料1被供应到两个辊7、7'之间的辊隙11'，在此一个辊7具有根据图4的压花结构并在压花结构的突起8之间具有包括大量开口14的穿孔结构(图4)。设有突起8的辊7被供应处于压力之下的液体，以便在开口14上产生液体射流，其在本发明的范畴中被称为水射流(水刺)，即使没有供应水，而是供应水状液体或其它液体时亦是如此。当无纺布材料1在辊7、7'之间的辊隙11'中被压花时，同时通过加载水刺使长纤维3和短纤维4混合和缠绕。由此形成一个由纤维混合物制成的无纺布层，该无纺布层在其厚度上含有短纤维4和长纤维3，并且在无纺布材料1的第一侧上短纤维4的浓度原则上预计略高，因为短纤维最初从那里被铺放。
此外，在图2中还可看出无纺布材料1被干燥并且随后被卷绕起来。
图3示出进一步的处理，在此根据本发明的一种优选方案，供应载体膜15并且在印刷单元16中为该载体膜设置装饰印样。接着，通过辊装置17将胶粘剂5图案状地施加到载体膜15上，然后设有图案状的胶粘剂5的载体膜15与无纺布材料1粘合，由此最终产生图1中所示的材料。
图5示例性示出一种适合用于连接无纺布材料1和载体膜15的胶粘剂图案。胶粘剂5的面积份额和因此连接区域的比值优选在10％和30％之间。胶粘剂5量在整个表面上优选平均在1.5g/m2和5g/m2之间。各个设有胶粘剂的接片宽度例如可在1至1.5mm的范围中。
例1：
在第一种实施例的范畴中，供应通过吹塑薄膜挤出(blown film extrusion)制出的由聚乙烯制成的厚度为14μm的单膜，该单膜在第一侧上设有装饰印样。然后，为该由包含PE-LLD(线型低密度聚乙烯)和PE-HD(高密度聚乙烯)的混合物制成的PE(聚乙烯)单膜设置具有根据图5胶粘剂图案的单组分聚氨酯胶粘剂和根据本发明的单位面积重量为35g/m2的无纺布材料1。无纺布材料1包括分别由聚丙烯制成的长纤维3和短纤维4。为粘合施加的胶粘剂的单位面积重量为3.0g/m2。
例2：
在其它参数相同的情况下，无纺布材料的单位面积重量从35g/m2提高到40g/m2。
对比例子：
如前所述构造的载体膜15在被印刷后被施加单位面积重量为1.8g/m2的且具有图5所示的胶粘剂图案的单组分聚氨酯胶粘剂，在此代替无纺布材料1粘合一种已知的由聚酰胺制成的单位面积重量为18g/m2的针织物。
表格1
表格2
表格1和2示出剥离测量以及剪切测量的结果。为了准备样品，在横向方向上正好剪切一条宽度为一英寸(24.4mm)的根据图2和3中所示的制造方法的无纺布材料。为了能够实现与钩定义的连接，样品随后被挂入悬挂装置中，接着用手将被加重500g重量的钩带按压到无纺布材料上3秒并且接下来在移走重量之前使钩带在重量负荷下悬挂在无纺布材料1上5秒。
进一步的测试使用兹韦克仪器的标准设置，在此将无纺布材料1插入下部夹头并且将钩带插入上部夹头中。在测量剪切力时(剪切测量)将钩带和无纺布材料1平面地设置在一个平面中。在测量剥离力(剥离测量)中，这样夹紧无纺布材料1，使得其从钩带起旋转180°折叠到自身上。然后在拉力试验中模仿旋转180°的剥离。
在试验参数变化时表明，在不同材料相互间的相对比较中以相同方式确定特定特性。因此具体所选择的试验程序仅仅是示例性的并且用于说明目的。
测量表明，借助根据本发明的无纺布材料的不同单位面积重量可达到甚至超过已知的纹路化的聚酰胺针织物的剥离值和剪切值，并且根据本发明的搭扣元件的特点在于极软的、均匀的且视觉上吸引人的表面。
