Description

转移染色方法 技术领域
本发明涉及纺织工业中的印染技术,具体是指一种转移染色方法。
背景技术
人类在发明纺织的同时,也发展了染色技术,早在1.5万年以前原始人就开始应用红色氧化铁矿物颜料对织物进行了染色,公元1450年欧洲的染色工业已略有规模,掌握了染色工艺和染料的应用。1471年欧洲各国的染色从业者齐集英国伦敦,讨论了染色工艺相关课题,通过了第一个会章,成立染色业者协会。第二次世界大战后,随着纺织工业的持续发展,带动了染料工业的发展。到二十世纪八十年代达到高峰,合成染料根据化学结构可细分为三十二类,根据应用分类亦可分为十八类,染料品种多达数万种。每一大类的染料又根据不同的染色性能和工艺条件又分成许多组别。同一种纤维常常可以用几种染料进行染色,而同一种染料也往往可以用于几种不同纤维的染色和印花。在染色和印花中所应用的染色机理和染色工艺则根据实际情况加以设计。在上个世纪九十年代,随着世界各国对环保和健康的重视,出台了大量关于印染环保条例的实施,使许多染厂面临研究与发展的压力。近年在染料的使用上,陈旧的染色、印花技术工艺正在逐渐被淘汰,而市场和社会需要印染企业从节省能源、环境保护、控制成本、提高效益、提高质量等与社会密切相关的主题出发以新的科学技术、信息工艺技术以及新的工艺引入纺织印染的生产程序中。
染色是借染料与纤维发生物理或化学的结合,或用化学方法在纤维上生成颜料,使整个纺织品具有一定色泽的加工过程。染色是在一定温度、时间、pH值和所需染色助剂等条件下进行的。染色产品应色泽均匀,还需要具有良好的染色牢度。现有织物的染色方法主要分浸染和轧染。浸染是将织物浸渍于染液中,而使染料逐渐上染织物的方法,它适用于小批量多品种染色。绳状染色、卷染都属于此范畴。轧染是先把织物浸渍于染液中,然后使织物通过轧辊,把染液均匀轧入织物内部,再经汽蒸或热熔等处理的染色方法,它适用于大批量织物的染色。传统染色上染纤维的过程可描述为:首先染料随着染浴的流动到达纤维周围;其次染料依靠本身的热运动扩散,通过纤维周围液层接近纤维表面;再次染料因分子间各种力的作用被纤维吸附,纤维周围的染 浴浓度随之降低;最后染料在纤维无定形区向纤维内部扩散并被吸附。而染浴的方式实际上是粗放型的生产方法,其生产过程中的耗水量巨大,且水洗后造成大量含染料有色废水的产生。我国每印染加工1吨纺织品耗水100~200吨,其中80~90%成为废水。是各行业中的排污大户之一。印染废水一般具有污染物浓度高,种类多,碱性大,水质变化大,COD含量高,含有毒有害成分及色度高等特点,属难处理的工业废水之一。随着社会的发展,个人、家庭生活品质提升,人们对于环保和健康的需求越来越强烈,粗放型的传统的染色方法已进入了被淘汰的落后产能的目录,例如2016年浙江绍兴近半的印染厂已关停,但是织物染色产品的需求仍然巨大,因此市场急需环保,低好水,低排放、高品质的织物染色工艺方法的开发和推广应用。相对而言,印花的耗水量远低于传统染色,实际上印花是一种局部的染色,染色时(特别是浸染),织物在染浴中有较长的作用时间,这使染料能较充分地扩散、渗透到纤维中去完成染着过程。而印花时,色浆中所加的糊料待烘干成膜后,高分子膜层阻止了染料向纤维内部扩散,使得染料附着在纤维表面,经汽蒸、焙烘等手段最终实现染料的固着。因此,采用印花的方式进行染色是实现节能减排的方向之一。

作为示例,图2示出了实现根据本发明的上述实施例1的转移染色方法的转移染 色设备。在进行染色时,织物依次经过该转移染色设备的如下部位:紧布架201;除尘单元300;双辊主动扩幅装置401;对中装置601;张力控制器603;主动牵引装置602;电晕处理器1100;第一张力摆杆装置604;第一上浆前扩幅装置402;第一上浆装置701和第二除湿装置702,用于在对织物的第一面进行染色之前对织物进行上浆和除湿;第二张力摆杆装置604’;第一纠偏单元800;第一染色单元100,用于对织物的第一面进行染色操作;烘干单元1000;第二上浆前扩幅装置402’;第二上浆装置701’和第二除湿装置702’,用于在对织物的与第一面相反的第二面进行染色之前对织物进行上浆和除湿;第三张力摆杆装置604”;第二纠偏单元800’;第二染色单元100’,用于对织物的所述第二面进行染色操作;烘干单元1000;张力摆臂装置605;和落布牵引装置202。
第一染色单元100用来实现上述实施例1中的步骤2和3。第二染色单元100’用来实现步骤6和7。第二染色单元100’的结构与第一染色单元100类似。为了方便描述,下面只对第一染色单元100进行描述,并简称为染色单元100。
染色单元是整个染色设备的核心,主要包括至少一个染色部套装置5和中心辊1,将在下面更详细地描述。每个染色部套装置包括满底版印刷版辊。在实施例1中该满底版印刷版辊为凹版版辊,但不限于此。该满底版印刷版辊可以是网纹辊(满底版凹版印刷版辊)、满底版柔版印刷版辊、满底版圆网印刷版辊或满底版胶版印刷版辊。中心辊和每一个染色部套装置都采用交流伺服电机独立驱动,中央控制单元中的运动控制器通过高速现场总线连接每一个交流伺服电机,从而实现中心辊和每一个染色部套装置的高精度同步控制。染色单元采用了交流伺服电机和运动控制器,可以实现预套准功能,大大减少材料浪费。所述染色单元100包括至少一个染色部套装置,使用多个颜色相同的染色部套装置进行染色操作的情况下,多次相同颜色的满底叠加可保证染色的均匀性;织物经过的运转中的染色部套装置的个数越多,染色颜色越深,通过对运转中的染色部套装置的个数进行控制,可实现对颜色深度的选择控制;对于需要染料具有渗透性的厚布或绒布染色,通过多次压合,或者不同压力梯度的多次压合,能够实现染料的充分渗透,保证染色效果。
参照图3-5,下面将更详细地描述染色单元100。如上所述,染色单元100主要包括中心辊1和至少一个染色部套装置5。该染色单元采用卫星式结构,所述至少一个染色部套装置共用一个中心辊作为背压辊。
在机架12上通过轴承固定连接中心辊1。中心辊1可以由变频电机13驱动旋转。中心辊1可以为表面包覆橡胶的硬质材料辊。表面橡胶邵氏硬度为85-90度,优选为90度。中心辊1的外径可以为1600-2000mm,优选为1800mm。可选地,该中心辊可以空腔注油,通过内置于空腔的电热棒加热油液,从而可将中心辊1温度升温到30-150℃。显然,本领域技术人员可以根据实际需要,采用其它升温方式控制中心辊的温度。中心辊可加热升温,能够稳定转移染色温度,避免由于季节变化或昼夜变化形成较大温差,导致批次间产品质量的不稳定;并且针对一些高支高密织物,通过加热可进一步膨胀待染色的织物纤维,从而增加染料上染率和上染速度。
中心辊1圆周外围分布有至少一个(例如2-8个,图3中示出了6个)染色部套装置5。每个染色部套装置5由各自的推进装置、例如推进缸506独立地提供其朝向中心辊1前进的推进力。推进缸506安装在各个染色部套装置5的的本体上,例如安装在本体的框架501上。
可选地,该转移染色设备还可以包括导辊4。更优选地,设置有至少两个导辊4。在待染色的织物与中心辊接触的入口和出口附近分别设置至少一个导辊。导辊4引导织物2进入或导出处于中心辊1和染色部套装置5之间的加压区间。优选地,每个导辊4可以为硬质材料辊。每个导辊的外径可以为100-150mm。
可选地,在各个染色部套装置5之间可以设置有烘燥箱7,用于确保墨水印后干燥,防止多次套准之间沾色串色的现象。特别地,参见图3,设置有五个烘燥箱7,其与六个染色部套装置5交替分布在中心辊1圆周外围。
可选地,依照本发明的转移染色设备还可以包括布置在中心辊1和染色部套装置5的非加压区间的在线中心辊清洗系统15。该在线中心辊清洗系统15包括清洗装置、刮水刀和烘箱,中心辊1表面经清洗装置清洗后,通过刮水刀刮除中心辊1表面水分,再经烘箱干燥后,即实现连续循环应用。清洗装置可以包括喷淋头和毛刷。
图4和图5显示了依照本发明的该实施例的转移染色设备的染色部套装置5。在所示的实施例中,染色部套装置5可以包括上述的推进装置(例如推进缸506)、墨斗组件510、网纹辊511、传墨辊512以及施压组件。墨斗组件510、网纹辊511、传墨辊512以及施压组件安装在框架501内。传墨辊512位于网纹辊511和中心辊1之间,可以与网纹辊511接触。传墨辊512与网纹辊511各自的轴端可以安装至框架501内的一安装块502内。该安装块502可在设置于框架501中的滑轨上滑动,这样,在推 进缸506的推进作用下,安装块502朝着中心辊1的方向运动,使得传墨辊512到达与中心辊1上的待染色的织物相接触的位置。在这里,推进缸506还可以提供使传墨辊512抵靠中心辊1上的待染色的织物的压力。根据本发明的实施例,各个推进缸506所提供的使传墨辊512抵靠中心辊1上的待染色的织物的压力可以为独立可调的。该压力通过控制系统调节设定,亦可以按照程序渐升,或按照程序渐降。整个染色部套装置5被推进缸506沿直线滑轨推动而实现与中心辊的离合,离合行程可达2-5cm。
网纹辊511的外径可选择使用,通常外径为95-200mm。网纹辊511配套一墨斗组件510。供墨系统将墨水输送到墨斗组件510与网纹辊511之间所形成的墨腔中。网纹辊511可以由伺服电机驱动,并与其它染色部套装置5的网纹辊511保持同步,从而保证套准精度。
优选地,传墨辊512可以为表面包覆橡胶的硬质材料辊。其表面可以包覆无缝橡胶。橡胶为天然橡胶、丁苯橡胶、聚氨酯橡胶或对水性墨水亲和性好的其它橡胶。优选地,传墨辊512的表面橡胶邵氏硬度为85-90度,更优选为90度。
由于每个染色部套装置传墨辊512为包覆橡胶的硬质材料辊,传墨辊512的外径略大于网纹辊511,如此在保证转移染色墨水完整的同时,提供了一定的容差空间。在转移染色过程中,当橡胶传墨辊与网纹辊接触时,橡胶传墨辊的橡胶在推进装置的推进作用下以及施压组件的施压作用下受到某一压力而发生变形;当网纹辊的当前表面转离橡胶传墨辊的橡胶表面时,橡胶表面能够迅速恢复原状。优选地,网纹辊511的外径<传墨辊512的外径≤网纹辊511的外径+1mm,也就是说传墨辊512的外径比网纹辊511的外径大,但两者的差在1mm以下。依照本发明的染色设备承压能力强,精度高,能够完整承载染色墨水,从而确保了转移后的染色墨水套准精度;此外,橡胶的压缩变形很小,从而能够承受每小时千万次的压缩,在生产周期内不会产生压缩疲劳而带来永久变形。
施压组件可以用于提供传墨辊512抵压网纹辊511的可调节压力。该施压组件用于调整墨量,以控制色差,压力主要用于把网纹辊网穴中的墨量粘出。在所示的实施例中,该施压组件包括致动器509和偏心轴套503。致动器509包括缸体和活塞杆。缸体可枢转地连接至安装块502。致动器509可以为液压类型、气动类型或电动类型。在致动器509为液压或气动类型的情况下,可以通过调节缸体的腔室内的流体压力,调节活塞杆伸出的长度。优选地,致动器509可以为伺服致动器,例如伺服电动缸。
该施压组件还可以包括摆臂508和连杆516。在所示的实施例中,摆臂508通过摆臂枢轴504可枢转地连接至该安装块502。摆臂508包括第一端部和第二端部。摆臂508的第一端部通过销轴可枢转地连接至致动器509的活塞杆的伸出端。摆臂508的第二端部通过销轴可枢转地连接至连杆516的一端。连杆516的另一端可枢转地连接至偏心轴套503。当然,对于本领域技术人员来说,除了在此所述的摆臂-连杆方式外,可以使用任何其它传动方式实现致动器509对偏心轴套503的转动操作。可选地,在摆臂枢轴的端部处可以设置手柄,以便在调试阶段由操作人员手动调节偏心轴套503的转动。
在根据本发明的另一实施例中,摆臂508可以包括第一臂部5081和第二臂部5082。每个臂部都包括第一端和第二端。所述第一端可以是小端,所述第二端可以是大端。第一臂部5081的第一端通过销轴可枢转地连接至致动器509的活塞杆的伸出端。第二臂部5082的第一端通过销轴可枢转地连接至连杆516的一端。第一臂部5081和第二臂部5082的第二端都不可枢转地连接至摆臂枢轴504。例如第二端可以设置有枢轴孔,摆臂枢轴通过键槽配合、定位销与销孔连接、或过盈配合等方式固定至第二端的该枢轴孔内。摆臂枢轴504可枢转地安装至安装块502。优选地,摆臂枢轴504从安装块502轴向向外延伸,形成伸出部。该伸出部可用于连接第一臂部5081和第二臂部5082的第二端。连杆516的另一端通过销轴可枢转地连接至偏心轴套503。
偏心轴套503整体上为套筒状的,但其外圆柱面的中心轴线与内圆柱面的中心轴线不共线,即两者偏移一定距离。偏心轴套503可转动地安装在安装块502的一轴套孔中。在所示的实施例中,偏心轴套503的外径略小于轴套孔的内径。偏心轴套可以围绕偏心轴套的外圆柱面的中心轴线相对于安装块502在该轴套孔中转动。可选地,偏心轴套503也有一部分轴向伸出安装块502,用于连接连杆516的所述另一端。参照图4,在根据本发明的一实施例中,偏心轴套可以通过在该轴向伸出的部分处设置的凸缘和安装在偏心轴套的另一端处的相对的限位块可转动地配合在安装块上,防止其在轴套孔中轴向运动,以保持其转动的稳定性。
传墨辊512的一个轴端通过轴承可旋转地安装在偏心轴套503内。传墨辊512的中心轴线与偏心轴套503的内圆柱面的中心轴线共线。由于偏心轴套503的外圆柱面的中心轴线与内圆柱面的中心轴线不共线,由此使得当偏心轴套在该轴套孔中转动时,偏心轴套的内圆柱面的中心轴线的位置会相应地发生变化,因此使得偏心轴套503内 的传墨辊512的轴端的位置也会相应地发生变化,并使得传墨辊512的中心轴线的位置发生变化,导致传墨辊512与网纹辊511之间的距离发生变化,由此引起两者之间的压力也发生变化。当偏心轴套转动而使传墨辊512运动至一抵压位置时,传墨辊512与网纹辊511之间的距离减小,两者抵压在一起,由此产生传墨辊512抵压网纹辊511的压力。而当偏心轴套转动而使传墨辊512运动至休止位置时,传墨辊512与网纹辊511之间的距离增大,两者脱离抵压(可以接触或者不接触),传墨辊512不向网纹辊511提供压力。
在工作时,根据需要可以通过施压组件转动偏心轴套而使传墨辊512运动至不同的抵压位置。通过转动偏心轴套503使传墨辊运动至不同的抵压位置,由于偏心轴套的上述偏心构造,可以调节传墨辊512与网纹辊511之间的距离,由此调节所产生的传墨辊512抵压网纹辊511的压力。并且由于橡胶具有柔性、回弹性、硬度小等特点,可以通过调节所产生的压力,精细地控制传墨辊512的形变,从而对于染色的套准而言,能够通过调节施压压力,进一步提升套准精度。
优选地,为了使整个传墨辊512在长度方向上均匀地对网纹辊511施加压力,传墨辊512的另一轴端侧设置有同样的另一施压组件。更优选地,传墨辊512的另一轴端侧的致动器可以省略,仅设置有摆臂、连杆和偏心轴套,即两个施压组件共用一个致动器509。传墨辊512两轴端侧的两个摆臂不可转动地固定至摆臂枢轴504,由此这两个摆臂借助于摆臂枢轴504同步枢转,从而实现两个连杆、偏心轴套的同步运动。
偏心轴套可以设定为初始位于休止位置。当施压时,致动器509致动而使活塞杆伸出,驱动摆臂508围绕摆臂枢轴504的中心轴线枢转,从而带动与摆臂508相连的连杆516运动,而连杆516的运动转而带动偏心轴套转动,偏心轴套503转动而使传墨辊512运动至一抵压位置(参照图4),传墨辊512与网纹辊511之间的距离减小,两者抵压,由此提供传墨辊512抵压网纹辊511的压力。相反,当不需要施压时,致动器509致动而使活塞杆缩回,驱动摆臂508围绕摆臂枢轴504的中心轴线枢转,从而带动与摆臂504相连的连杆516运动,而连杆516的运动转而带动偏心轴套503转动,偏心轴套503转动而使传墨辊512运动至休止位置,传墨辊512与网纹辊511之间的距离增大,两者脱离抵压,由此传墨辊512不再向网纹辊511施加压力。致动器509的活塞杆的行程可设置为80-200mm,优选100mm。
中心辊1、传墨辊512与网纹辊511的轴线是平行的。优选地,三者的轴线可以 不共面。从图3和4所示的示意图中可以看到,三者的轴心不共线。优选地,三者的轴心连线形成从130到170度范围内的夹角,该夹角优选为146度或147度。另外,从图4的示意图中还可以看到,摆臂枢轴504大体上布置在网纹辊511的与传墨辊侧相对的一侧上。即,网纹辊511、传墨辊512、摆臂枢轴504三者的轴心成三角形布置。这样布置的优点在于,能够减小染色部套装置在与中心辊1的轴线垂直的方向上的尺寸,使框架以及安装块结构紧凑;另外,零件维护、更换方便。
而且,在推进缸506的推进作用下安装块502朝着中心辊1的方向运动时,如图6所示,传墨辊512抵压中心辊1的推压力F1的方向平行于滑轨的长度方向,即平行于染色部套装置的纵向中心线。该推压力F1可以分解为垂直和切向两个分量。垂直分量是指垂直于中心辊外周表面、即向着中心辊的中心的实际染色压力F2,此染色压力的大小体现为橡胶辊的橡胶变形量。切向分量是切向于中心辊外周表面的切向分力F3,该切向分力F3对橡胶辊包胶层的切向变形有一定影响,但对染色图案的变形影响很小。对于同一批次的染色作业而言,所需的染色压力F2应当保持不变,因此在传墨辊-中心辊中心连线与水平线之间的夹角β确定的情况下,推压力F1和切向分力F3的大小与染色部套装置的纵向中心线和水平线之间的夹角α的大小有关,夹角α越小,推压力F1和切向分力F3就越大;反之,夹角α越大,推压力F1和切向分力F3就越小。通过提供切向分力F3,可以控制橡胶辊包胶层的切向变形。
在一实施例中,染色部套装置的纵向中心线和水平线之间的夹角α可为0-90度,优选为15度。网纹辊-传墨辊中心连线与染色部套装置的纵向中心线的夹角角度可以为4-35度,优选为23度。
优选地,染色部套装置还可以包括用于将传墨辊512和网纹辊511之间的压力锁定的压力锁定器517,从而避免生产过程中,由于织物2表面不平整导致的压力值的微跳动。所述压力锁定器可以包括长度可变的部件,该部件的一端可枢转地连接至偏心轴套503,另一端可枢转地固定至安装块502。该部件的长度随着偏心轴套503的转动而发生变化。当传墨辊512抵压网纹辊511的压力根据需要通过致动器509调节至所需值时,操作人员可以通过任何适合的手段使该压力锁定器517锁定,从而使该长度可变的部件的长度恒定,借此保持传墨辊512抵压网纹辊511的压力恒定。
依照本发明的转移染色设备经转移染色产品的生产应用,产能和产品质量方面取得较好效果。各个染色部套装置可以借助于各自的推进装置而独立地压力接触或脱离 中心辊,以便其它染色部套装置继续转移染色,并且能够独立地调节抵靠中心辊的压力。采用传墨辊为转移暂载体,无纸张耗材的消耗,不仅降低运行成本,且绿色环保,经济实用。此外,本发明的转移染色设备可实现高速转移染色生产,染色速度可高达30-60m/min。
双面染色可以共用一个烘干单元1000,也可以设置两个单独的烘干单元。
对第一面进行染色的染色单元100和对相反的第二面进行染色的染色单元100’可以为不同的颜色,从而可实现双面异色染色。这是传统染色工艺所不能实现的。
此外,在两个染色单元中设置的施压组件,能够可调地提供传墨辊抵压网纹辊的压力,从而能够适应不同的织物属性和织物厚度,有效控制染色效果。
虽然已经参照特定的示例性实施例展示和描述了本发明,但是本发明不受这些示例性实施例的限制。应该认识到的是,本领域的技术人员能够在不脱离本发明的由权利要求书或者其等同内容所限定的范围和精神的情况下对这些示例性实施例进行变化和变型。
