Abstract
一种造纸机或工业织物的制造方法,需要用压电喷头阵列将聚合树脂材料施加在基材上的预选位置上,该阵列以平均直径为10μ(10微米)或更大的液滴沉积聚合树脂材料。例如,预选位置可以是组成该织物的纱线交织形成的结节,或者是纱线之间的空隙。如此精确地施加树脂的目的是为了控制织物的功能特性,例如渗透性和耐磨性等。聚合树脂材料以适合其成分的方式定形,且可选择研磨,从而使基材表面上的聚合树脂材料具有均一的厚度。
Description
技术领域
本发明部分涉及造纸技术,具体地说,本发明涉及一种在造纸机上用于在其上造纸的织物,一般称之为纸机织物。本发明还涉及通过例如水刺法制造非织造物和非织造织物,具体地说,本发明涉及所谓的工业织物,非织造物和非织造织物在其上制成。再更具体地说,本发明是关于通过使聚合树脂材料受控地沉积在织物上,以提供具有所需功能特性的织物。
背景技术
如本领域技术人员所公知的,在造纸机成形部中,造纸过程首先是将纤维浆即纤维素纤维的水分散液沉积到移动的成形织物上。在此过程中,浆体中大量的水分通过成形织物排出,而纤维网则留在成形织物的表面上。
刚形成的纤维网从成形部进入压榨部,压榨部包括一系列压榨压区。纤维网由压榨织物支撑,或者通常情况下位于两层压榨织物之间,通过压榨压区。在压榨压区内,纤维网受到压缩力的作用,该压缩力将其中的水分挤出,并使网中的纤维成分彼此粘附,使得纤维网转变为纸幅。从纤维网中挤出的水分由一层或多层压榨织物所吸收,并且理想的情况是不回到纸幅中去。
纤维网现在为纸幅,最后进入干燥部,干燥部至少包括一个可转动的干燥转鼓系列或转筒系列,这些转鼓或转筒由蒸汽在内部进行加热。纸幅本身由干燥织物引导着以弯曲路径依次绕行该系列中的每个转鼓,且干燥织物将纸幅紧紧地贴在至少部分转鼓的表面。加热的转鼓通过蒸发作用使纸幅的含水量降低至所需的水平。
应该了解的是,成形、压榨及干燥织物都在造纸机上采用无端环(endless loop)的形式,并且都起到输送带的作用。应该进一步了解的是,纸张生产是一种以相当快的速度进行的连续过程。也就是说,在成形部内,纤维浆连续地沉积到成形织物上,而刚生产出的纸幅在离开位于造纸机下游末端的干燥部后,就被连续地卷绕到辊筒上。
非织造产品的生产也为本技术领域所公知。这类织物不经过常规的纺丝、机织或针织操作,而直接由纤维制成。取而代之的,这些织物可通过纺粘法或熔喷法制成,在这些方法中,当刚挤出的纤维在挤出后仍为又热又粘的状态时将其铺成网状,从而使其互相粘合形成整块的非织造网。
非织造产品也可以通过气流成网法或梳理操作来制成,在此操作中,当沉积完成后,纤维网通过针刺或水刺法固结成非织造产品。在水刺法中,高压水喷头垂直向下地将水喷在纤维网上,使纤维互相纠缠在一起。在针刺法中,纤维的缠结利用往复运动的刺针床机械地达到,在各针进入冲程时刺针床使纤维网表面上的纤维进一步进入内部。
在此过程中,环状工业织物起着重要的作用。通常,这些织物是由塑料单丝织成的,但是在非织造物的制造过程中,当温度条件不能或不适合使用塑料单丝时,可使用金属线来代替塑料单丝。至于作为造纸机用布时,这些工业织物也会以输送带的方式来操作,这些纤维网会按照前述的方法以连续方式成网并固结。
在上述各种情况中,如果造纸机或工业织物在连续生产过程中用作环状输送带,则环状织物的内表面会接触使用该织物的机器的固定构件,并会由于这些接触而容易磨损。为延长织物的使用寿命,织物的内表面上会施加一层耐磨的聚合树脂材料。以往,用于施加该涂料的技术包括喷涂或轻触辊式涂敷。但这些技术的缺点是不够精确,并且会因为不均一且不受控制的方式而负面影响织物的渗透性。由于渗透性的局部差异能明显影响工业织物上所制成的纸张或非织造产品的品质,因此需要一种用于将聚合树脂材料的耐磨层施加到环状织物内表面上的方法,该方法不会负面影响其渗透性特征。
同样地,例如为了改善工业织物对其上所制纸张或非织造织物的输送(handling或conveyance),还需要在环状织物的外表面上施加这种层或涂料,而不会负面影响其渗透性。举例来说,美国专利5,829,488披露了一种将用于造纸机的单程干燥部上的干燥织物,该干燥织物是一种在干燥部中有面向纸幅的所谓纸幅面的织物结构。干燥织物在纸幅面上至少有部分纱线是亲水性的,以增大干燥织物和纸幅之间的附着力。可通过将亲水性聚合树脂材料涂覆在纸幅面上,而制成亲水性的纱线。但用常规方法,即喷涂或轻触辊式涂敷,很难做到如此操作而不会负面影响该织物的渗透性。
最后,还需要一种能以受控方式将聚合树脂材料施加至造纸机或工业织物上的方法,以在织物的所选区域中或贯穿整个表面将其渗透率调整至所需值。可用该方法来消除局部与织物所需的均匀渗透性之间的差异,或用来将织物的渗透率调整至某一所需的均匀值。例如,此前有这样一种努力,通过改变织物边缘处的MD纱支数(较紧密以降低渗透性),而使其中央部分具有较低的纱支数以获得较高的渗透率,以在横机器方向获得更均匀湿度的形状,但此方法也有缺点。
本发明提供一种可满足这些需求的方法,其中能将聚合树脂材料高度控制并精确地施加至造纸机或工业织物的表面上,从而不影响其渗透性,并达到所需效果或者以所需方式来影响织物,例如改变表面接触面积和耐磨性,而对渗透率或对比变化、空隙容积或局部渗透性差异影响最小。
发明内容
因此,本发明是一种具有功能特性,例如渗透性或耐磨性的造纸机或工业织物的制造方法,其功能特性通过将聚合树脂材料精确地施加至织物表面或内部来控制。该方法包括第一步骤,为织物提供基材。
由至少一个压电喷头将聚合树脂材料以平均直径为10μ(10微米)或更大的液滴沉积在基材的预选位置上。然后以适当的方法将树脂材料定形或固定。
如果所要控制的是耐磨性或纸幅输送,则预选位置可以是例如,织物纱线交织而在其表面上形成的结节。如果渗透性是所要控制的功能特性,则预选位置可以是纱线之间的空隙。
然后,可选择研磨树脂材料涂层,以使基材表面上的树脂具有均一的厚度,从而改善表面平滑度或增加接触面积。
现将参照以下附图对本发明进行更完整详细的说明。

具体实施方式
根据本发明来制造造纸机或工业织物的方法首先要提供基材。通常,基材是由单丝纱线所织成的织物。但更广泛地,基材也可为机织物、非织造物、螺旋链结物或针织物,由任何用来制造纸机织物的纱线构成,或由用来制造非织造物及非织造产品生产所用工业织物的纱线构成,例如单丝纱线、捻合单丝纱线、复丝纱线和捻合复丝纱线。该纱线可由本技术领域中的普通技术人员为此目的而使用的聚合树脂材料中的任意一种挤出而成。所以,各种聚酰胺、聚酯、聚氨酯、芳香族聚酰胺、聚烯烃族的树脂,以及其它树脂都可使用。
或者,基材也可由网眼织物构成,例如在共同转让的Johnson的美国专利4,427,734中所示,其所披露内容在此以引用方式并入本文。基材还可为多个美国专利中所示出的各种螺旋链结带,例如Gauthier的美国专利4,567,077,其所教导内容在此也以引用方式并入本文。
此外,基材还可依据共同转让的Rexfelt等人的美国专利5,360,656所示的方法,通过将机织物、非织造物、针织物或网眼织物条螺旋缠绕而制成,该专利所披露内容以引用方式并入本文。因此,该基材会包括螺旋缠绕的条状物,其中各螺旋捻圈由连续接缝与相邻捻圈接合,从而使该基材沿纵长方向形成环状形式。
基材并非仅有上述几种可能形式。任何在纸机织物及相关领域中的普通技术人员所使用的各种基材都可替代其而使用。
当提供基材之后,可通过本领域中的普通技术人员所熟知的方法,可选地将一层或多层短纤毛层附于该基材的一面或两面上。最公知及最常用的方法可为针刺法,此方法中由多个往复动作的刺针将毛层内的个别短纤维驱入基材内。或者,也可通过水刺法将个别短纤维附于基材上,在此方法中,细的高压水柱发挥如同前述的往复刺针的相同作用。应该了解的是,由任意一种上述方法,或本领域中的普通技术人员所知的其它方法,将短纤毛层附在基材上之后,其结构会类似于压榨织物,即一般在造纸机的压榨部用来将湿纸幅脱水的各种压榨织物。
在某些情况下,需要在施加树脂之后,再将初始层或附加毛层施加于结构物上。在该情况下,图案化的树脂会贴在一层毛层纤维底下。此外,树脂层也可铺设在叠层中,或夹在两层基材之间,例如以防止“集聚(nesting)”,或达到其它所需效果。
不论基材的一面或两面是否有附加的短纤维毛层材料,一旦提供基材后,就将其安装在图1示意性示出的装置10上。应该理解的是,基材可为环状形式,或在安装于造纸机上的过程中可缝成环状形式。因此,图1所示的基材12应理解为基材12的整体长度的较短部分。若基材12为环状形式,则最常用的方法是将其绕装在一对辊上,该辊虽未示于图中,但为纸机织物技术领域中的普通技术人员所熟知。在此情况下,装置10设在基材12的两个走向中的其中一个上,最方便的是顶部走向上,该基材12位于两个辊之间。但是,不论是否为环状,在制造过程中优选将基材12置于适度的张力下。此外,为了避免松垂,在基材12穿过装置10时,可用水平支撑件从底下对其进行支撑。
现在更具体地参照图1,在实施本发明的方法时,基材12示为以向上的方向移动通过装置10,装置10包括一连串的几个站,基材12可逐步通过各站而制成织物。
各站描述如下:
1.可选的聚合物沉积站14;
2.成像/聚合物精确沉积站24;
3.可选的定形站36;以及
4.可选的研磨站44。
在第一站,即可选的聚合物沉积站14中,压电喷头阵列16安装在横轨18、20上,并沿垂直于基材12通过装置10的方向在横轨上移动,以及平行于基材12运动的方向在两根横轨之间移动,可使用压电喷头以重复步骤沉积,从而将所需量的聚合树脂材料累积到基材12上或其内,而基材12静止不动。与例如利用喷涂等常规技术所完成的沉积相比,可视需要来利用可选的聚合物沉积站14将聚合树脂材料更加均匀地沉积到基材上。但应该理解,聚合物沉积站14会无差别的将聚合树脂材料施加至基材12的纱线上,以及纱线之间的间隔或空隙内。但并非所有的应用都需如此,因此在本发明中聚合物沉积站14是可以选择使用的。
此外,材料的沉积除了可横越基材的移动方向以外,还可平行于其移动方向,或螺旋于其移动方向,或适用于此目的的任何其它方式。
压电喷头阵列16至少包括一个但优选包括多个由电脑控制的独立的压电喷头,各喷头发挥泵的作用,其动作构件为压电元件。若技术上许可,则可利用多达256个压电喷头或更多喷头所组成的阵列作为实施物。动作构件为晶体或陶瓷,通过施加电信号使之物理变形。此变形能使晶体或陶瓷发挥泵的作用,在每次接收到适当的电信号时就会机械地喷出一滴液体材料。因此,这种使用压电喷头响应电脑控制的电信号来供应所需材料液滴的方法,通常称为“按需喷滴”法。
再参照图1,压电喷头阵列16从基材12的边缘开始,或优选从纵向延伸于其中的基准线开始,贯穿基材12进行纵向和横向移动,而基材12则静止不动,将聚合树脂材料以标称直径为10μ(10微米)或更大如50μ(50微米)或100μ(100微米)的极小液滴的形式沉积到基材12上。压电喷头阵列16相对于基材12的纵向与横向移动,以及从阵列16的各压电喷头喷出的聚合树脂材料液滴的沉积,都是以受控方式由电脑来控制的,即控制所形成图案的三个平面内:长、宽和深或高(x、y、z维度或方向)平面内的形状,重复实施,从而在基材12的各单位面积上,以所需的聚合树脂材料的形状累积所需材料量。
在本发明中,使用压电喷头阵列将聚合树脂材料沉积在基材12表面上或其内,聚合树脂材料的选择受下述要求所限制:在输送时,即聚合树脂材料在压电喷头的喷嘴内准备沉积时,其粘度应为100cps(100厘泊)或更小,从而使各喷头能以固定的液滴输送速度来提供聚合树脂材料。限制聚合树脂材料选择的第二个要求为,当聚合树脂材料以液滴从压电喷头落向基材12时,或当其附着在基材12上之后,必须部分定形,以避免聚合树脂材料流动,并保持对聚合树脂材料的控制,以确保其在附着于基材12的地方仍保持液滴形式。符合这些要求的适用聚合树脂材料包括:
1.热熔性材料及湿气固化的热熔性材料;
2.基于聚氨酯及环氧树脂的两组分反应体系;
3.由聚氨酯、聚酯、聚醚和硅酮所衍生的反应性丙烯酸酯单体及丙烯酸酯低聚物组成的感光聚合物组合物;以及
4.包括丙烯酸树脂与聚氨酯的水性胶乳和水性分散物以及微粒填充混合物。
应该理解的是,聚合树脂材料在沉积于基材12上之后,需要固定在基材12上或其内。用来定形或固定聚合树脂材料的方式取决于其本身的物理及/或化学要求。感光聚合物用光来固化,而热熔材料则通过冷却来定形。水性胶乳和分散物先干燥再加热固化,而反应性体系则受热固化。因此,聚合树脂材料可通过固化、冷却、干燥或其任意组合来定形。
喷头沉积材料的精确度取决于所形成结构的尺寸和形状。使用的喷头种类和所涂材料的粘度也会影响所选喷头的精确度。
为了控制聚合树脂材料在基材12内的渗入及分布,即,将该材料控制并限制于基材12的所需范围内或表面上,必须将其适当固定。这种控制对防止基材12表面之下的渗渍与扩散是极为重要的。这种控制可通过将基材12保持在一定温度而实现,这种温度会使功能性树脂材料在接触时快速定形。也可在具有一定开孔度的基材上使用某些材料来实现控制,这种材料具有已知或明确的固化或反应时间,因此聚合树脂材料还来不及扩散超出基材12的所需范围,就已经定形。
当已经在横轨18、20之间的区带中,横贯基材12将所需量的聚合树脂材料施加到各单位面积时,如果需要,则基材12纵向前进与该区带等宽的量,并重复上述过程,从而在与之前已完成的区带相邻的新区带上施加该聚合树脂材料。以此重复方式,可为整个基材12提供任何单位面积所需的聚合树脂材料量。
或者,压电喷头阵列16仍从基材12的边缘开始,或优选从纵向延伸于其中的基准线开始,并相对于横轨18、20保持在固定位置,而基材12则在该阵列之下移动,从而在环绕基材12的纵向条带中施加任何单位面积所需的聚合树脂材料量。当完成该纵向条带后,压电喷头阵列16在横轨18、20上横向移动与该纵向条带等宽的量,并重复上述过程,从而在与之前已完成的条带相邻的新的纵向条带中施加聚合树脂材料。如果需要,可以以此重复方式,为整个基材12提供单位面积所需的聚合树脂材料量。
压电喷头阵列16可在基材12之上通过一次或多次,以沉积所需的材料量,并制成所需形状。在这方面,该沉积物可采用如图3概括示出的任何一种形状。形状可为方形、圆锥形、矩形、卵形、梯形等具有较粗的底部而向上逐渐变细的形状。当喷头重复通过沉积区域时,依照所选的设计方案而定,所沉积的材料量会以递减的方式层叠。
在横轨18、20的一端,设有喷头检查站22,以检测由压电喷头阵列16中的各压电喷头喷出的聚合树脂材料的流量。在该处净化和清洁压电喷头,从而使任何有故障的压电喷头单元自动恢复操作。
在本发明中唯一的非选择性操作站第二站中,即成像/聚合物精确沉积站24中,横轨26、28支撑数码相机30和压电喷头阵列32,该相机可横贯基材12的宽度移动,该压电喷头阵列可横贯基材12的宽度移动并可在两根横轨26、28之间相对于横轨纵向移动,而基材12保持不动。
数码相机30检查基材12的表面,以定位出基材12的纱线及纱线之间的间隔或空隙。实际表面与所需外观之间的比较,通过与数码相机30配合操作的图案快速识别(FPR)处理器来完成。FPR处理器将信号传给压电喷头阵列32,以将聚合树脂材料沉积在所需位置处以符合所需外观。例如,如果需要将聚合树脂材料以某种次序填充在间隙中,从而以所需方式控制织物的渗透性,则可通过成像/聚合物精确沉积站24来达到此效果。要注意的是,如图4A~C所示,纱线13与其上方纱线15之间的空隙11,可通过在纱线19上控制沉积树脂材料17来填充,从而使表面均一且平坦。
或者,如果聚合树脂材料只是要沉积在纱线上,而不是要沉积在它们之间的空隙内,则也可通过成像/聚合物精确沉积站24来完成。如同前述,压电喷头检查站34也会设在横轨26、28的一端,以检测各喷头喷出的材料流量。在该处,压电喷头阵列32中的各压电喷头将会被净化及清理,以使任何有故障的压电喷头单元自动恢复操作。
在第三站,即可选的定形站36中,横轨38、40支撑定形装置42,该装置在使所用的聚合树脂材料定形时会需要。定形装置42可为热源,例如红外线、热空气、微波或激光源;冷空气;或紫外线,或可见光源,根据所用聚合树脂材料的需要进行选择。
最后,第四站,即最后一站为可选的研磨站44,在该处采用适当的研磨使任何聚合树脂材料在基材12的表面平面上具有均匀的厚度。可选的研磨站44可包括具有研磨表面的辊,和设在基材12的另一面上的另一个辊或支撑表面(backing surface),以确保研磨能造成均匀厚度。
举例来说,现在参照图2,该图是依据本发明将聚合树脂材料沉积在基材12表面上精确位置的平面图。基材12由纵向纱52和横向纱54以单层平纹织造而织成,但是应该了解,本发明的实施并不限制于这种织物。纵向纱52在通过横向纱54上方处形成结节56,同样地,横向纱54也在通过纵向纱52上方处形成结节58。纵向纱52与横向纱54之间由交织形成许多空隙60。
图2是从装置10的可选的定形站36和可选的研磨站44离开时所呈现的成品织物平面图。织物62具有确定的预选空隙60,空隙由成像/聚合物精确沉积站24所精确沉积在这些预选位置处的聚合树脂材料64所阻塞,从而以预定方式控制织物62的渗透性。此外,涂料64也涂敷在各结节56、58上。当图2所示视图为织物62的背面时,则涂层64就可用来防止磨损,或者当该视图为织物62的纸幅面时,就可用来改善纸幅输送。涂层64由成像/聚合物精确沉积站24精确地施加到结节56、58。
要注意的是,图案可为随机形式,或在基材上重复的随机图案,或在带与带之间重复的图案,以控制品质。
该表面通常是与所制造的纸张、面纸、纸巾或非织造产品接触的表面。可以预见,有些织物/制造过程需要将树脂主要施加在不与产品接触的表面上。在本发明的可替代实施例中,可选的聚合物沉积站14、成像/聚合物精确沉积站24及可选的定形站36也可调整为用螺旋技术将基材12制成织物,而非如前文所述的沿横机器方向进行。在螺旋技术中,可选的聚合物沉积站14、成像/聚合物精确沉积站24及可选的定形站36从基材12的一个边缘开始,例如,从图1的左侧边缘开始,并在基材12沿图1所示方向移动时,逐渐地横越基材12进行移动。将各站14、24、36及基材12的移动速率设成,能使成品织物上的所需聚合树脂材料以连续方式按需在基材12上螺旋。在此可替代的方案中,当各捻圈通过可选的定形装置42底下时,由可选的聚合物沉积站14和成像/聚合物精确沉积站24所沉积的聚合树脂材料,可部分定形或固定,而在基材12全部通过装置10后,完全定形。
或者,可选的聚合物沉积站14、成像/聚合物精确沉积站24及可选的定形站36都保持在彼此对齐的固定位置中,而基材12则在纵向条带上。当该纵向条带完成后,可选的聚合物沉积站14、成像/聚合物精确沉积站24及可选的定形站36横向移动与纵向条带等宽的量,并在与之前已完成条带相邻的新的纵向条带上重复进行该过程。以此重复方式,整个基材12能根据需要完全处理。注意,压电喷头阵列中的部分独立的压电喷头可用于沉积一种聚合树脂材料,而其它的喷头则可用于沉积不同的聚合树脂材料,例如制成具有一种以上聚合树脂材料微区的表面。
此外,整个装置可与加工材料保持在固定位置。应该注意的是,该材料并不需要是全宽度的织物,也可为例如在Rexfelt的美国专利5,360,656中所披露的材料条,然后再制成全宽度的织物,该专利所披露内容在此以引用方式并入本文。在完全加工后,条带可为未缠绕的,并将其卷在一组辊上。可收存这些成卷的织物条,然后可采用例如刚刚提到的上述美国专利中的教导内容,来制成环状的全宽度结构物。
对于本领域技术人员来说,可以容易地对上述实施方案进行多种修改和改进,或应用于其它领域,而不偏离本发明的目的、精神和范围。所有这些改动均在本发明权利要求范围内。树脂可以以任何填充空隙和覆盖纱线的图案来施加。树脂在纱线长度方向上可以是连续或不连续的并提供耐磨性。虽然以上披露了用压电喷头在基材上或其内的预选位置上沉积功能性聚合树脂材料,但其它能以所需尺寸范围来沉积液滴的装置也为本领域普通技术人员所公知,或将来会开发出来,且这些装置也可用来实施本发明。例如,在需要较大尺寸图案以使最后元件形如圆凸半球体的制造过程中,较大型,甚至单独的树脂沉积喷嘴,也可构成整个喷头阵列。使用这种装置也在本发明的权利要求范围内。
