Description

生产平面构型物品的方法
技术领域
本发明涉及一种用于生产由至少部分分裂的纱线、纤维或长丝制成的平面构型物品(Flaechengebilde)的方法。
背景技术
由文献EP 0814188已知一种容易分裂的共轭/复合纤维的生产(方法)。这种纤维通过一个纺丝工艺由两种基本上不相容/配伍的原料如聚对苯二甲酸乙二醇酯和聚酰胺纺成，且通过机械力如喷水处理分裂成单根长丝/单纤维丝(Elementarfaeden)。由文献JP A 10096119，JP A 2000017519或JP A 2001181931已知这样的共轭纤维和由该纤维制成的织物，即该纤维由两种相容/配伍的聚合物通过一纺丝过程生产并通过一个分裂处理分裂成单根长丝。文献DE 10080786和EP A0953660也描述了一种纺织物，该纺织物由相容/配伍的聚合物纺成并通过一随后的分纱工序分成横截面较小的纤维。在此需要在聚合物的相界处使用分离剂或专门的腐蚀技术。
发明内容
本发明的目的是，给出一种简化由可裂开的纱线、纤维或长丝制成的平面构型物品的生产过程的方法，提高分裂的程度，即实现至少部分地分裂由相容的聚合物制成的共轭纤维。
按本发明该目的通过这样的纱线、纤维或长丝实现，该纱线、纤维或长丝至少由两个单根长丝形成，由共同的喷丝头生成且形成一平面构型物品，当温度处于所使用的聚合物的玻璃化转化温度(Tg)和熔化温度之间时，该平面构型物品至少被致密化至密度为所用聚合物密度的10％，以使在随后进一步的机械力的作用下实现至少部分地分裂为单根长丝。令人吃惊的是，在处于上述区域的温度和超过上述限值的致密化的作用下，由不相容的聚合物制成的共轭纱线、纤维或长丝几乎可以完全分裂为单根长丝，且由相容聚合物制成的纱线、纤维或长丝至少部分地实现分裂为单根长丝。
该方法有利地这样实现，即致密化过程在最大比熔化温度最低的聚合物的熔化温度低10℃的温度下进行。由此可以达到最大的分裂结果，而平面构型物品中的纱线、纤维或长丝不会发生熔化。
特别优选的是这样一种方法，由该方法产生的基础平面构型物品被压缩至密度为所用聚合物密度的15％。在这种压缩程度下由不相容的聚合物制成的纱线、纤维或长丝可以达到大于99％的分裂程度，同时还减小了用于高压喷水处理的能量消耗。相对于一种根据现有技术已知的高压喷水分裂和加固(粘合)方法，这种方法只需要两个处理步骤。
有利地借助一个辊轧机进行基础平面构型物品的压缩。这种压缩可以特别简单地整合到连续的整理工序中。
分裂为单根长丝的过程有利地借助一液力流体处理过程在压力为120-500巴时进行。根据共轭纱线、纤维或长丝的成份在压力为120-500巴的液力流体处理导致一至少部分地分裂到几乎完全分裂成单根长丝，并导致由此产生的平面构型物品的缠绕和加固。
所述纱线、纤维或长丝的单根长丝特别优选地设计为微单根长丝(Mikroelementarfden)。分裂为微单根长丝使得形成具有非常细小孔隙的平面构型物品。在根据本发明的方法中优选地使用熔融纺制的长丝或也可使用短纤维。
由至少两根微单根长丝构成的所述纱线、纤维或长丝优选地由以下各组中选出的相容的聚合物制成：聚乙烯/聚丙烯(PE/PP)、聚对苯二甲酸乙二醇酯/聚对苯二甲酸丁二醇酯(PET/PBT)、聚对苯二甲酸乙二醇酯/聚邻苯二甲酸亚丙基酯(PET/PTT)、聚对苯二甲酸乙二醇酯/再循环聚酯(PET/R-PES)、聚对苯二甲酸乙二醇酯/聚乳酸酯(PET/PLA)、聚酯/共聚多酯(PES/CoPES)、聚酰胺/共聚多酰胺(PA/CoPA)、尼龙6/尼龙66(PA6/PA66)和尼龙6/尼龙12(PA6/PA12)。另外由至少两根微单根长丝构成的所述纱线、纤维或长丝优选地由以下各组中选出的不相容的聚合物制成：聚酯/聚酰胺(PES/PA)、共聚多酯/共聚多酰胺(CoPES/CoPA)、特别是聚对苯二甲酸乙二醇酯/聚酰胺(PET/PA)和再循环聚酯/聚酰胺(R-PES/PA)。再循环聚酯特别是指由商业上的PES瓶得到的材料。

具体实施方式
实施例1
一种成网织物由连续的双成分长丝制成，所述长丝的单根长丝以桔瓣或蛋糕切块(派)的形式垂直于横截面设置。在文献FR 7420254中描述的一个相应的工艺，并在此用作参考。该成网织物由聚对苯二甲酸乙二醇酯/尼龙66(PET/PA66)制成，所述两种组分以70∶30的重量百分比率包含于长丝中。所述聚合物具有以下添加成分和性能：
    聚酯     聚酰胺
TiO2添加成分     0.8％     0.4％
熔点     259℃     256℃
290℃时的熔化粘度     150Pa·s     110-1150Pa·s
密度     1360kg/m3     1130kg/m3
原料聚合物在烘干后，对于PET在285℃而对于PA66在280℃进行挤出，并通过一个在285℃的温度下工作的喷丝头以大约4500m/min(75m/s)的喷丝速率和1g/孔/min(60g/孔/h)的通过量纺成丝。接下来长丝冷却，进入一个拉伸过程并铺置成一成网织物，如前述文献FR 7420254中已经描述的。该成网织物单位面积的重量为大约130g/m2，并在成网过程之后直接输送给一个具有两个加热到160℃的金属辊子的辊轧机，该辊子具有15daN/cm宽的挤压力并以10m/min(600m/h)的速度运行。辊轧过程使得平面构型物品具有570kg/m3(所述聚合物密度的44.15％)的密度。温度和压力以及辊轧过程中剪切力的共同作用导致了长丝的预分裂。
在辊轧之后，通过高压喷水处理将所述成网织物几乎完全分裂为单根微长丝，对其进行涡流变形并由此加固该成网织物。完成所述液力加固的条件和手段基本上对应于文献FR 7420254中所作的描述。分裂后单根长丝具有0.15dTex的纤度。
实施例2
按照上述根据FR 7420254的工艺生产一种由聚对苯二甲酸乙二醇酯/尼龙6(PET/PA6)制成的连续的双组分长丝，在该长丝中单根长丝以在横截面上观察为蛋糕切片的形状交替布置。与实施例1的不同之处在于，PA6在约260℃时挤出。其它纺丝的条件对应于实施例1中的情况。
    聚酯     聚酰胺
  TiO2添加成分     0.8％     0.4％
  熔点     259℃     224℃
  290℃时的熔化粘度     150Pa·s
  260℃时的熔化粘度     160Pa·s
  密度     1360kg/m3     1130kg/m3
通过在两个加热到180℃的板件之间以300bar的压力挤压长丝，模仿上述辊轧条件，其中温度和压力的共同作用导致长丝的预分裂。
实施例3
由双组分的短纤维制成一种成网织物。该短纤维具有聚对苯二甲酸乙二醇酯组分的V形横截面，在该短纤维的端部设置有尼龙6组分。由此得到的成网织物具有50g/m2的单位面积重量，并在成网过程之后直接在两个加热到180℃的板件之间以300bar的压力挤压。温度和压力的共同作用导致长丝的预分裂。
实施例4
由连续的共轭长丝制成一种非织造成网织物，所述长丝由聚对苯二甲酸乙二醇酯/聚对苯二甲酸丁二醇酯(PET/PBT)组成，其重量百分比的份额为70∶30，所述长丝以类似于文献FR 7420254中描述的工艺制造。该PET组分相应于实施例1的情况，其它纺制条件也与实施例1中的条件一致。
PBT组分在250℃时挤出。
    PET     PBT
    TiO2添加成分     0.8％     0.4％
    熔点     259℃     225℃
    290℃时的熔化粘度 150Pa·s 350Pa·s
    密度     1360kg/m3     1300kg/m3
由此得到的成网织物具有170g/m2的单位面积重量，并在成网过程之后直接在两个加热到200℃的板件之间以400bar的压力挤压。由此成网织物的密度达到770kg/m3(所述聚合物密度的57.38％)。温度和压力的共同作用导致长丝的预分裂。
对比示例1
以与实施例4中所述相同长丝组成成分和布置，在相同的纺制条件下制成一种连续的成网织物。该成网织物在成网过程之后直接放入炉中以200℃加热30秒钟。成网织物的密度为110kg/m3(聚合物密度的8.2％)。在该处理完成之后以基本上对应于文献FR 7420254中所述的条件和手段通过液力加固对该成网织物进行处理。只进行过温度处理的该成网织物不会分裂为单根长丝。
对比示例2
以与实施例4中所述的相同的纺制条件制成一种连续的带相同长丝组成成分和布置的成网织物。在成网过程之后直接在室温下以400bar的压力对该成网织物进行挤压。由此成网织物的密度达到370kg/m3(聚合物密度的28.65％)。在上述条件下不会实现分裂为单根长丝的分裂程度。
实施例5
一种成网织物由连续的双组分长丝以相应于文献FR 7420254中描述的过程制成，所述长丝的单根长丝以桔瓣形设置。所述长丝由聚对苯二甲酸乙二醇酯/聚邻苯二甲酸亚丙基酯(PET/PTT)以70∶30％的重量份额组成。PTT组分在250℃时挤出。PET组分及其纺制条件与实施例1中描述的条件一致。
    PET     PTT
TiO2添加成分     0.8％
熔点     259℃     240℃
290℃时的熔化粘度     150Pa·s     500Pa·s
密度     1360kg/m3     1350kg/m3
成网织物具有130g/m2的单位面积重量，并在成网过程之后直接通过一个具有两个加热的金属辊子的辊轧机挤压致密。其中一个金属辊子是具有52齿/cm2刻纹的辊子，另一个是在160℃温度下工作的光滑辊子。在30daN/cm宽挤压力和15m/min(900m/h)的辊轧速度下，成网织物的密度达到760kg/m3(聚合物密度的56.0％)。在辊轧之后，对所述成网织物进行喷水处理，该处理过程导致单根长丝的分裂和涡流变形。
