Description
技术领域
本发明涉及将热塑性树脂制的单轴取向体以取向轴相互交叉的方式经纬层叠或编织而形成的网状体及其制造方法。
背景技术
在专利文献1中记载有如下网状体(网状无纺布)的制造方法,该网状体是通过层叠纵向(长度方向)取向的热塑性树脂制的单轴取向体(纵向网状物)和横向(宽度方向)取向的热塑性树脂制的单轴取向体(横向网状物)而形成的。在该网状体的制造方法中,通过在独立形成的纵向网状物与横向网状物相互叠置的状态下进行按压、加热,从而使纵向网状物与横向网状物一体化。
现有技术文献
专利文献
专利文献1:日本特许第2983584号公报
发明内容
发明要解决的问题
专利文献1所记载的这样的网状体由于具备了透气性及透明性,因此能够被用作用于包装蔬菜、水果等食品的包装材料。因此,在制造网状体时,进行上述按压时例如通过将纵向网状物和横向网状物导入一对镜面辊之间并对它们施加夹持压力而使它们彼此面粘接继而一体化,从而确保作为包装材料的强度(尤其是剥离强度)。
但是,当使用镜面辊来进行上述按压时,网状体的表面被平滑化,因此网状体带光泽(光亮)。因此,若将具有光亮的网状体用作食品用的包装材料,则来自网状体的反射光增强,其结果存在导致作为包装对象物的食品的识别性下降这样的问题。
本发明鉴于这样的现状,将在确保网状体的强度的同时抑制由网状体的光泽所引发的包装对象物的识别性下降作为课题。
用于解决发明的手段
因此,本发明的网状体的制造方法包括:在将热塑性树脂制的单轴取向体以取向轴相互交叉的方式经纬层叠或编织之后,使相邻接的单轴取向体的接触部位彼此面粘接而形成网状体的工序;以及对网状体的表面实施粗糙加工的工序。
此外,本发明的网状体是将热塑性树脂制的单轴取向体以取向轴相互交叉的方式经纬层叠或编织而形成的,其具备:面粘接部,其是使相邻接的单轴取向体的接触部位彼此面粘接而形成的;以及凹凸部,其是利用粗糙加工形成在网状体的表面的。
发明的效果
采用本发明,通过使相邻接的单轴取向体的接触部位彼此面粘接而形成网状体,能够使上述单轴取向体彼此的粘接面积最大化,因此能够充分地确保网状体的强度。
此外,采用本发明,通过对网状体的表面实施粗糙加工而能够抑制网状体的光泽,因此在将网状体用作包装材料的情况下能够抑制包装对象物的识别性下降。

具体实施方式
以下基于附图说明本发明的实施方式。
图1A和图2A表示构成本发明的一实施方式的网状体的第1例的单轴取向体。
图1A所示的裂口网状物1对应于本发明的热塑性树脂制的单轴取向体,是通过沿着纵向(裂口网状物1的取向轴1a的轴向)单轴拉伸热塑性树脂制的薄膜后在纵向上对其进行割纤并且进行展宽而形成的。详细地说,裂口网状物1是通过如下方法而形成的:在沿着纵向(长度方向)拉伸多层薄膜之后,使用开纤器(splitter)在同方向上交错地割纤(开纤处理,split treatment)从而形成网状的薄膜,进而展宽至规定宽度,该多层薄膜是使用第一热塑性树脂和具有比第一热塑性树脂的熔点低的熔点的第二热塑性树脂并利用多层吹塑法、多层T模头法等成形法制作而成的,且该多层薄膜至少包含两层(图中为三层)。此外,遍及整个宽度方向,裂口网状物1在纵向上具有较高的强度。另外,图中的附图标记2对应于干纤维,附图标记3对应于支纤维。
图1B是图1A的B部的放大立体图,裂口网状物1由在第一热塑性树脂层4的两面层叠了第二热塑性树脂层5而成的三层结构构成。第二热塑性树脂层5能够在形成后述的无纺布8(网状体的第1例)时作为与后述的狭缝网状物6一起经纬层叠时的网状物相互间的粘接层发挥作用。在此,作为第一热塑性树脂列举有聚乙烯等。此外,作为熔点比第一热塑性树脂的熔点低的第二热塑性树脂列举有聚乙烯等。

图2B是图2A的B部的放大立体图,狭缝网状物6由在第一热塑性树脂层4’的两面层叠了第二热塑性树脂层5’而成的三层结构构成。第二热塑性树脂层5’能够在形成后述的无纺布8(网状体的第1例)时作为与裂口网状物1一起经纬层叠时的网状物相互间的粘接层发挥作用。
图3表示构成本实施方式的网状体的第2例和第3例的单轴取向体。
图3所示的单轴取向带7对应于本发明的热塑性树脂制的单轴取向体。单轴取向带7是使多层薄膜沿着纵向或横向单轴取向并进行裁切而形成的多层拉伸带,该多层薄膜是使用第一热塑性树脂和具有比第一热塑性树脂的熔点低的熔点的第二热塑性树脂并利用多层吹塑法、多层T模头法等成形法制作而成的,且该多层薄膜至少包含两层(图中为三层)。图3所示的单轴取向带7与裂口网状物1和狭缝网状物6相同,由在第一热塑性树脂层4”的两面层叠了第二热塑性树脂层5”而成的三层结构构成。第二热塑性树脂层5”能够在形成后述的无纺布9(网状体的第2例)时作为经纬层叠单轴取向带7时的带相互间的粘接层发挥作用。此外,第二热塑性树脂层5”能够在形成后述的织布10(网状体的第3例)时作为编织单轴取向带7时的带相互间的粘接层发挥作用。另外,图中的附图标记7a对应于单轴取向带7的取向轴。
图4~图6表示本实施方式的粗糙加工前的网状体的三个例子(上述网状体的第1例~第3例)。
图4表示作为本实施方式的网状体的第1例的无纺布8。无纺布8是将裂口网状物1和狭缝网状物6经纬层叠而形成的。在无纺布8中,以裂口网状物1的取向轴1a与狭缝网状物6的取向轴6a相互正交的方式经纬层叠。此外,在无纺布8中,相邻接的裂口网状物1与狭缝网状物6的接触部位彼此面粘接。另外,作为无纺布8的具体例,能够列举Warifu(注册商标,JX Nippon ANCI.Inc制)。
图5表示作为本实施方式的网状体的第2例的无纺布9。无纺布9是将平行排列单轴取向带7而成的构件两组层叠而形成的。在无纺布9中,以一组单轴取向带7的取向轴7a与另一组单轴取向带7的取向轴7a相互正交的方式经纬层叠。此外,在无纺布9中,相邻接、交叉的单轴取向带7的接触部位彼此面粘接。
图6表示作为本实施方式的网状体的第3例的织布10。织布10是将单轴取向带7编织而形成的。在织布10中,单轴取向带7彼此相互正交,因此取向轴7a彼此相互正交。此外,在织布10中,相邻接、交叉的单轴取向带7的接触部位彼此面粘接。
接着,使用图7说明本实施方式的单轴取向体的制造方法的一例。
图7表示作为单轴取向体的裂口网状物1的制造方法的概略。
如图7所示,裂口网状物1主要是经过如下工序制造而成的:(1)多层薄膜的制膜工序、(2)多层薄膜的取向工序、(3)平行于取向轴地对取向多层薄膜开纤的开纤工序、以及(4)卷取开纤后的薄膜的卷取工序等。
以下说明各工序。在图7中,(1)在多层薄膜的制膜工序中,向主挤出机11供给第一热塑性树脂,向两台副挤出机12、12供给作为粘接层树脂的第二热塑性树脂,且将从主挤出机11挤出的第一热塑性树脂作为中心层(取向层),将从两台副挤出机12、12挤出的第二热塑性树脂作为内层和外层,通过吹塑成形制作环状多层薄膜。另外,图7示出了使用三台挤出机通过多层环状模头13向下吹出热塑性树脂并利用水冷吹塑机14来制膜的情况。
(2)在取向工序中,将上述制膜而成的环状多层薄膜切分成两片薄膜F、F’并使它们通过具备红外线加热器、热风输送机等的烘箱15内,在加热至规定温度的同时,相对于初始尺寸以规定的取向倍率进行辊取向。
(3)在开纤(割纤)工序中,使上述取向的多层薄膜与高速旋转的开纤器(旋转刀刃)16滑动接触,从而对薄膜进行开纤处理(割纤化)。
在割纤形成的裂口网状物1展宽至规定宽度之后,经过热处理部17的热处理,继而在(4)卷取工序中卷取为规定的长度,成为裂口网状物1的卷取体18。
接着,使用图8和图9来说明本实施方式的网状体的制造方法的两个例子。
作为本实施方式的网状体的制造方法的第1例,图8示出了层叠了两片裂口网状物1而成的无纺布的制造方法。
在图8中,由原卷抽出辊(original-cloth roll-out roll)110a抽出如图7所示地制造的裂口网状物110(纵向网状物),使其以规定的供给速度行进至展宽工序111,利用展宽机(未图示)展宽数倍,根据需要进行热处理。与纵向网状物同样地由原卷抽出辊210a抽出其他裂口网状物210(横向网状物),使其以规定的供给速度行进至展宽工序211,利用展宽机(未图示)展宽数倍,根据需要进行热处理,之后切断成与纵向网状物的宽度相等的长度,并从相对于纵向网状物的薄膜行进垂直的方向供给,在层叠工序112中隔着粘接层(第二热塑性树脂层5)以各网状物的取向轴相互正交的方式经纬层叠。在热压接工序113中,将经纬层叠的纵向网状物和横向网状物顺序导入外周面为镜面的热滚筒113a与镜面辊113b、113c之间并施加夹持压力。由此,纵向网状物与横向网状物被相互热压接而一体化。此外,相邻接的纵向网状物与横向网状物之间的接触部位彼此整体面粘接。如此一体化后的纵向网状物和横向网状物在卷取工序中被卷取,从而成为经纬层叠无纺布的卷取体114。
另外,在图8中,替代裂口网状物110、210可将织布10输送至热压接工序113,将织布10导入热滚筒113a与镜面辊113b、113c之间并施加夹持压力。在该情况下,通过对织布10施加夹持压力,构成织布10的单轴取向带7被热压接而一体化。此外,相邻接、交叉的单轴取向带7的接触部位彼此整体面粘接。
作为本实施方式的网状体的制造方法的第2例,图9示出了层叠了裂口网状物1和狭缝网状物6而成的无纺布8的制造方法。
无纺布8的制造方法主要包括如下工序:(1)多层薄膜的制膜工序、(2)相对于多层薄膜的长度方向垂直地进行开缝处理(slit treatment)的开缝工序、(3)多层狭缝薄膜的取向工序、以及(4)使纵向网状物(裂口网状物1)与横向网状物(狭缝网状物6)层叠并进行热压接的压接工序。
以下说明各工序。在图9中,(1)在多层薄膜的制膜工序中,向主挤出机311供给第一热塑性树脂,向副挤出机312供给作为粘接层树脂的第二热塑性树脂,且将从主挤出机311挤出的第一热塑性树脂作为内层,将从副挤出机312挤出的粘接层树脂(第二热塑性树脂)作为外层,通过吹塑成形来制作环状两层薄膜。另外,图9示出了使用两台挤出机通过多层环状模头313向下吹出热塑性树脂并利用水冷吹塑机314来制膜的情况。
(2)在开缝工序中,夹紧上述制膜而成的环状两层薄膜而将其扁平化,接着,通过压延进行微取向,在横向开缝工序315中相对于行进方向垂直地对形成三层结构的薄膜交错地开设横向狭缝。
(3)在取向工序中,利用横向取向工序316对进行了上述开缝处理的薄膜实施横向取向。将如此获得的狭缝网状物6(横向网状物)输送至(4)热压接工序317。
另一方面,与图8的纵向网状物同样地由原卷抽出辊410a抽出裂口网状物410(纵向网状物),使其以规定的供给速度行进并送至展宽工序411,利用展宽机(未图示)展宽数倍,根据需要进行热处理。之后,将纵向网状物送至热压接工序317,在此使纵向网状物与横向网状物以各自的取向轴交叉的方式层叠,继而进行热压接。具体而言,通过将纵向网状物和横向网状物顺序导入外周面为镜面的热滚筒317a与镜面辊317b、317c之间并对它们施加夹持压力,从而使它们相互热压接而一体化。由此,相邻接的纵向网状物与横向网状物之间的接触部位彼此整体面粘接。将如此一体化后的纵向网状物和横向网状物送至卷取工序而被卷取,从而成为无纺布8的卷取体318。
在本实施方式中,对上述网状体(图4和图5所示的无纺布、图6所示的织布、以及利用图8和图9所示的制造方法制造的各个无纺布)进行作为粗糙加工的压纹加工。以下,作为被施以压纹加工的网状体的一例,使用无纺布8来进行说明。
图10是表示本实施方式的压纹加工工序的图。
压纹辊510在其表面具有多个圆形的凸部(未图示)。此外,压纹辊510被加热至无纺布8能够软化的温度(例如100℃左右)。
在压纹辊510的下方配置有作为该压纹辊510的支承辊而发挥作用的橡胶辊520。
在压纹加工工序中,无纺布8被导入压纹辊510与橡胶辊520之间并被上述辊施加夹持压力。在对无纺布8施加夹持压力期间,利用压纹辊510的圆形的凸部在无纺布8的表面形成圆形的凹部。在此,形成在无纺布8表面的圆形的凹部对应于本发明中的“利用粗糙加工形成在网状体表面的凹凸部”。
另外,在图8和图9所示的网状体的制造方法中,压纹加工工序可以安排在热压接工序与卷取工序之间、或卷取工序之后的任意阶段。
图11A是压纹加工前的无纺布8的放大照片。此外,图11B是压纹加工后的无纺布8的放大照片。
在图11A中,示出了使裂口网状物1与狭缝网状物6之间的接触部位彼此面粘接而形成的面粘接部8a。
另一方面,在图11B中,示出了利用压纹加工而形成在无纺布8表面的圆形的凹部8b。凹部8b遍布无纺布8整个表面地形成,由此抑制了无纺布8的光泽。
图12的(A)表示由未实施压纹加工的无纺布8形成的包装袋21。此外,图12的(B)表示由实施了压纹加工的无纺布8形成的包装袋22。
比较包装袋21和包装袋22时,包装袋22与包装袋21相比抑制了光泽。因而,由于通过对无纺布8实施压纹加工而抑制了包装袋的光泽,因此能够提高包装袋内收纳的包装对象物的识别性。
在日本特开平11-302961号公报中,作为使多个单轴取向体彼此一体化的方法,记载有所谓的加热压纹粘接法。在这样的粘接方法中,例如使用图10所示的压纹辊510和橡胶辊520,将加热了的压纹辊510的凸部按压于被粘接体(层叠化后的多个单轴取向体),由此热压接被粘接体。
但是,在使用加热压纹粘接法来热压接被粘接体的情况下,被粘接体中不与压纹辊510的凸部接触的部分未被施以热压接。因此,采用加热压纹粘接法有可能导致相邻接的单轴取向体的接触部位中存在未粘接的部分,结果网状体有可能无法确保充分的强度(尤其是剥离强度)。
关于这一点,在本实施方式中是将被粘接体导入热滚筒与镜面辊之间并施加夹持压力来热压接被粘接体的。由此,相邻接的单轴取向体的接触部位彼此整体面粘接,因此网状体能够确保充分的强度(尤其是剥离强度)。
采用本实施方式,关于构成网状体(图4和图5所示的无纺布、图6所示的织布、以及利用图8和图9所示的制造方法制造的各个无纺布)的单轴取向体,使相邻接的单轴取向体的接触部位彼此面粘接。由此,能够使上述单轴取向体彼此的粘接面积最大化,因此能够充分地确保网状体的强度。
此外,采用本实施方式,通过对网状体的表面实施压纹加工而能够抑制网状体的光泽,因此在将网状体用作包装材料的情况下,能够抑制包装对象物的识别性下降。
另外,在本实施方式中,对于使用压纹辊的凸部为圆形的情况进行了说明,但是凸部的形状并不局限于此,例如,也可以是矩形或椭圆形。
此外,在本实施方式中,将压纹加工用作对网状体表面实施的粗糙加工并进行了说明,但是粗糙加工的手法并不局限于此,例如,作为粗糙加工能够使用喷砂加工等物理处理和/或利用溶剂等的化学处理。
