Abstract

本发明涉及一种纺织件(A;A1、A2)的生产方法,所述生产方法包括形成缝合线缝(c1、c2、c3;C)的步骤。该缝合线缝步骤还用于将电子标签(1)固接至纺织件(A;A1、A2)。电子标签(1)是由包括有线电子器件的条带形成的,有线电子器件包括与至少一个天线导线(3b)相关联的芯片(3a),芯片(3a)和天线导线(3b)被布置在缝合线缝(c1、c2、c3;C)内部。本发明还涉及设有标签的纺织件。

Description

设有包括有线电子器件的电子标签的纺织件与这种纺织件的 生产方法
技术领域
本发明涉及诸如服装的纺织件的电子识别标签领域。
背景技术
在该领域中使用的标签通常是由名称“RFID标签”(表述“射频识别”的首字母)来标示的。这种标签包括具有被联接至天线的射频发射-接收功能的电子识别芯片。
根据第一常规方法,天线是由被布置在塑料支承件或纸质支承件上的导电轨形成的。芯片是通过结合至支承件来进行组装的,以便将该芯片的连接焊盘分别放置成与形成天线的导电轨相接触。该支承件通常具有矩形形状,其长度和宽度具有几厘米的尺寸,以便能够容纳天线的必要尺寸并且便于处理该标签。
在相关的Anglo-Saxon文献中,由芯片及其支承件组成的功能组件被通称为术语“嵌体”。这种嵌体通常被共同制造在背衬条带上,并且可以以卷的形式获得。
为了由嵌体形成电子识别标签,通常将该嵌体包装在(例如,由塑料制成的)保护壳中,如专利US8212676所记载的。在前述文献中,这样形成的标签的尺寸相对较大:高5mm、长150mm且宽22mm。
为了便于将识别功能集成到纺织产品中,已经进行了将导线形状因子赋予电子标签的尝试。因此,文献US6329917、WO2016038342、WO2011161336、GB2472025、GB2472026、US20110147462、WO2008080245或WO2019175509是已知的,它们并入有在其长度上间隔开的纺织纱线,以及天线和电子芯片。
“纺织纱线”或更简单地“纱线”指的是可以被编织或并入纺织产品中的元件。因此,它们具有在纺织领域中常规的拉伸强度、柔韧性以及形状因子,以便由服装工业中可用的常规设备进行处理。这种并入天线和RFID电子芯片的纺织纱线可以在其制造期间被集成到纺织产品中,或者在制造它们之后被固接至这些产品。
举例来说,可以提供的是,在织物的织边处使用RFID纺织纱线作为纬纱线或经纱线,该织物可以具有非常大的尺寸。通过沿着形成织物的纬纱线或经纱线的RFID纱线布置以规则间隔隔开的RFID器件,可以自动识别织物的长度,例如,在圆柱形支承件上沿该织物的缠绕方向。
因此,文献WO2009136837提出将应答器放置在纺织件的线缝中。该应答器是由被连接至形成天线的两个导电导线部分的二极管以及这些导线之间的与该二极管并联的有线传输线来形成的。将该应答器封装在介电材料中。该文献提出的应答器的处理对于服装领域中的传统设备是困难的。该应答器没有被固接至纺织件,并且特别地,它可以在线缝中滑移。将应答器缝制到纺织件是不容易的,因为在制作这种线缝时刺伤这种应答器并使其不起作用的风险很高。
文献FR3036823提供了使用RFID模块的“电”天线导线来将并入该RFID模块的标签附接在纺织件上。将天线缝制到标签上;该天线在该标签的任一侧延伸:因此,它没有被集成到标签中。该文献的RFID模块体积大,这是因为在这种模块中,将芯片连接至磁性天线,而该磁性天线通常是由在用于保持芯片的衬底上布置成环的导电轨形成的。将该模块集成到线缝中需要多个剪裁操作,包括缝制“电”天线导线,这使得将该模块集成到线缝中不适合于该解决方案的体积部署。
本发明旨在提供一种不同于现有技术的电子识别标签。本发明还旨在提供一种巧妙地并入该电子识别标签的纺织产品。
发明内容
为了实现这些目标之一的至少部分目标,本发明的目的是提供一种纺织件的生产方法,所述生产方法包括形成缝合线缝的步骤,所述生产方法的特征在于,该缝合线缝步骤还用于将电子标签固接至纺织件,该电子标签是由包括有线电子器件的条带形成的,该有线电子器件包括电连接到至少一个天线导线的芯片,该芯片和天线导线被布置在缝合线缝内部。
根据本发明的其它有利和非限制特征,单独地或以任何技术上可行的组合来采用:
-该缝合线缝是选自包括以下项的列表的线缝:单股暗缝线迹、包边线迹、缎纹或Z形线迹、包缝线迹、覆盖线迹、直线迹;
-该缝合线缝包括包缝线迹,并且其中,该芯片和天线导线被布置在包缝线迹的线圈下方;
-该电子标签是通过缝合线缝的至少部分缝合线缝而缝制到纺织件的;
-该芯片是具有射频发射-接收功能的电子识别芯片;

具体实施方式
参照图1a和图1b,描述了形成本说明书的第一方面的电子识别标签1。标签1具有矩形(并且更一般地为梯形)形状,并且长度为几厘米(通常介于3cm至20cm之间)。标签1的角可以具有圆形形状。标签1的长度足以容纳RFID器件3的天线导线3b,如将在本说明书的其余部分中变得显而易见的。有利地,该天线导线3b是沿标签的长度以直线方式延伸的。它可以从标签的一个端部延伸至另一个端部,如图1a所示,或者接近这些端部而不接合它们,如图1b所示。也可以将天线导线3b沿着标签的对角线布置,这使得可以使其更紧凑。还可以提供的是,天线导线不是完全直的,而是在标签的平面中具有至少一个曲率,以便能够适应标签的任何弹性变形。标签1的宽度通常小于其长度,通常小于1厘米,并且通常介于2mm至8mm之间。标签的厚度可以介于0.1mm至2mm之间。
图1a和图1b的示例的标签1是由两个纺织条带部分2a、2b组成的,这两个部分是通过它们的主面彼此组装和密封的。将RFID纱线3的节段夹持在这两个面之间,所述节段包括电子芯片3a和天线导线3b。该条带部分以及因此的标签具有足够的柔韧性,从而不会修改它们打算要集成到的纺织件的柔韧性。类似地,它们可以具有可以与该纺织件的弹性相符合的弹性。因此,它们可以具有介于0%(并且在这种情况下是被集成到牛仔裤中或者被集成到工作服的厚帆布中,即,由不可能拉长的织物制成的纺织件中)至100%(并且能够被集成到由弹性纤维构成的纺织件中)之间的拉长能力,并且优选为具有约5%至20%的量级的拉长能力(被集成到像T恤等的经典针织品中的纺织件中)。
由于要集成到纺织件中,因此使用纺织条带来构成标签1形成了其优选实施方式;然而,这不是唯一的可能实施方式。因此,条带部分2a、2b可以由广泛种类的材料组成或者包括广泛种类的材料,这些材料是根据所使用的密封技术或者根据标签打算集成到的纺织件的性质来选择的。
举例来说,并且当这两个条带部分通过焊接进行密封时,所述部分中的至少一者包括在中等温度(例如小于400℃,并且通常介于100℃至400℃之间)下可熔的材料。该温度必须高于标签在其使用期间很可能经历的处理的温度,并且低于将导致芯片3a暴露于过高温度(通常为200℃的量级)的温度。这样的可熔材料可以对应于通常在服装领域中使用的热塑性材料(诸如聚酰胺,其熔点为约250℃;或者聚酯,其熔点为约200℃至250℃)。该可熔材料也可以对应于塑料材料。
不必将条带部分2a、2b的所有表面密封在一起:因此标签可以仅具有位于例如形成其长度的边缘(并且可能地形成宽度的边缘)附近的焊线或焊点。当这些焊点或焊线因此是外围的并因此距离电子芯片3a相对远时,将条带焊接在一起可以局部且短暂地将这些条带暴露于超过其熔化温度的温度,但是电子芯片3a本身并不暴露于高于约200℃的温度。
当通过在所述条带部分中的至少一者上施加粘合剂层或者借助于线缝来促进密封时,可以更自由地选择从中提取部分2a、2b的条带的性质。
这些条带部分2a、2b中的至少一者也可以由具有一个可熔材料层和另一不可熔材料(诸如棉)层的层压件来形成。然后,不可熔层形成标签1的所述暴露表面中的至少一个暴露表面,这使得可以赋予其外观和纹理,从而允许其容易地集成到纺织件中。
在所有情况下,标签1的RFID纱线节段3包括至少一个电子识别芯片3a,该电子识别芯片具有射频发射-接收功能,并且被以电方式组装至形成“电”发射-接收天线的至少一个导电导线3b上。在本说明书的其余部分中,“有线电子识别器件”将是指被以电方式组装至被包括在RFID纱线的节段中的至少一个天线3b(至少一个导电导线或至少一个导电轨)的芯片3a,并且“RFID纱线”将是指具有有线形状因子并且包括沿其长度布置的多个有线电子识别器件的部件。
如本申请的介绍中所述,这种RFID纱线节段3可以以多种方式来生产。
特别地,它可以是在本申请的介绍中描述的RFID纱线。在这种纱线中,有线电子识别器件通常是由至少一个纺织覆盖纱线覆盖的,例如通过缠绕该覆盖纱线来覆盖。还可以提供一种包芯纱线,有线电子识别器件是沿着该包芯纱线共线地或者以螺旋方式布置的。除了覆盖纱线和/或包芯纱线之外或者作为覆盖纱线和/或包芯纱线的替代,还可以提供的是,利用封装材料来涂覆有线电子识别器件,该封装材料可以是通过挤制而形成的塑料。
文献EP2585628和WO2019175509(通过引用并入本说明书中)公开了与本说明书兼容的RFID纱线的各种优选实施方式,但其并不形成唯一的可能实施方式。这些文献特别提供了这样的实施方式,即,根据该实施方式,可以将有线电子识别器件以均匀隔开且选定的间隔并入到纺织纱线中。在这些文献所描述的RFID纱线(被统称为“缠绕式”)中,有线电子识别器件的天线导线是共线地布置的或者以螺旋方式围绕包芯纱线布置的,该天线导线可以具有弹性特性。当天线导线是以螺旋方式布置时,天线导线的拉长能力强,这使得这种RFID纱线的节段特别适合于并入弹性纺织件。
使用覆盖纺织纱线和/或通过利用保护材料进行涂覆来保护有线电子识别器件具有保护形成天线的导线的优点。特别地,该导线没有穿过夹持有该导线的条带部分2a、2b(特别是当这些部分2a、2b是由纺织材料制成时)。当集成了RFID纱线节段的标签1被固接至易于起皱(例如在该纺织件洗涤期间)的纺织件时,会导致这种现象。
应注意,被并入标签1中的RFID纱线节段3不是必须采用刚刚呈现的“缠绕式”纺织纱线的形式,即使该实施方式是优选的。
因此,RFID纱线可以由有线电子识别器件的简单链来组成,即,由通过形成天线的至少一个导电导线(并且优选为两个导电导线)链接在一起的多个电子识别芯片来组成。这种链确实构成本说明书的含义内的RFID纱线。在文献US8782880、EP2810299或WO2018193198(通过引用并入本申请)中将可以找到关于这种链的可能特征的附加细节。可以提供的是,通过利用覆盖纱线缠绕该链或该链的部分,或者通过利用保护材料(诸如树脂)涂覆或挤压该链或该链的部分,从而保护该链或该链的部分。因此,这种链的节段是电子芯片3a组成的,在该电子芯片的焊盘上已经以电方式组装了(例如通过焊接)形成天线的导电导线,其整体可以(至少部分地)并入保护材料中。这种节段可以极佳地适合于集成夹持在两个条带之间,并且适合于形成根据本说明书的标签1。
还可以设想RFID纱线是由被组装在有线条带上的芯片组成的,在该有线条带上布置了形成天线的细长且导电的轨。这些轨可以通过沉积薄铝层来形成,这本身是公知的。将芯片组装(例如,通过黏合)至有线条带,以便使它们的连接焊盘与导电轨相接触,并由此形成多个有功能的有线电子识别器件。有线条带可以由塑料、纸或织物制成。导电轨也可以由一个或更多个导电线形成、被缝制或刺绣在条带中,而不管该条带是由织物、塑料还是纸形成的。还可以设想将轨印刷在条带上。术语“有线条带”是指条带具有平坦表面,其宽度必须与根据本说明书的电子识别器件的有线形状因子兼容,并且宽度小于1mm或2mm。该有线条带在一部分已经被切割以隔离有线电子识别器件时的长度是由必需的天线长度来规定的,并且通常介于3cm至20cm之间。
为了制造RFID纱线条带,将形成天线的导电轨沿着衬底长度上的行形成在非常大尺寸(例如1m至2m宽(例如1.4m),并且其可以是几十米长)的衬底上;然后,将RFID电子芯片组装在该衬底上,以便使它们的连接焊盘与导电轨或与所缝制的导电导线相接触。在该步骤之后,可以沿着所述行切割条带衬底,并由此形成本实施方式的采用条带形式的RFID纱线,其可以被绕在线轴上。
应注意,除了发射-接收和识别功能之外,标签1的电子芯片3a还可以被配置成除了识别功能之外的其它功能,诸如(温度、湿度、压力的)测量功能甚或发光功能。
在图1所示的标签1中,RFID纱线节段3包括单个芯片3a。可以提供的是,在条带部分2a、2b之间集成多个电子芯片,各个芯片皆可能具有相同的识别功能(出于可靠性理由)或者不同的功能(例如,一个芯片具有识别功能,而另一芯片具有独特的测量功能)。例如在文献EP3319168中呈现了这种配置的示例。还可以提供的是,在两个薄膜2a、2b之间放置(例如彼此平行的)多个纱线节段3。
有利地,RFID纱线节段3是沿着标签的边缘并且平行于标签的边缘布置的(在所示示例的情况下是沿着标签的长度)。它可以在其宽度上居中,如图1所示。因此,在标签上和RFID纱线节段的每一侧上存在“惰性”表面,该惰性表面能够使标签1附接至纺织产品而不影响RFID纺织纱线的操作,如将在本说明书的其余部分中详细说明的。
标签1的暴露表面(即,条带部分2a、2b的未被接合在一起的主表面)可以用作印刷表面,以例如接收视觉识别码(条形码、QR码)和/或人们想要与该标签打算附着其上的纺织产品相关联的任何其它文本信息。
为此,如图2所示,可以提供具有延伸形状的电子标签,以便能够将该视觉码4a和/或该文本消息4b置于所述暴露表面中的至少一个暴露表面上。在这种情况下,可能有利的是,不将RFID纱线放置在标签的宽度的中心,而是沿着并靠近该标签的侧边中的一个侧边。
在所有情况下,人们将选择保留RFID纱线节段与标签的边缘之间的最小距离d,这使得可以限定足够宽的惰性材料条带以放置线迹,从而允许标签被固接在纺织件上。该最小距离d可以介于1mm至4mm。
可以以非常简单的方式大量且高速地生产电子标签1。参照图3,用于制造标签1的方法包括供应非常长的RFID纱线5的步骤,该RFID纱线因此包括大量有线电子识别器件。RFID纱线可以采用线轴5a的形式,并且供应步骤可以包括退绕该线轴。各个电子识别器件皆由图3中标示电子芯片3a的点来象征。如已经提及,长RFID纱线5可以对应于缠绕式RFID纱线,或者电子识别器件链,或者采用其“条带”形式。
在图3的制造方法中,从其线轴5a退绕的RFID纱线5被引导成定位在两个条带6a与6b之间。这些条带也可以采用线轴的形式来供应。可以提供多个导辊或压具8以及引导件以引导并同步地驱动条带6a、6b和RFID纱线5的移动。
在该移动期间,并且在RFID纱线5被夹持在所述两个条带6a、6b之间的区域处,将这两个条带6a、6b彼此密封以便以形成功能化条带(即,连续条带,在该连续条带上和沿着该连续条带布置有线识别器件)。
如已经在前面的段落中详细说明的那样,条带6a、6b的相应性质与所采用的密封技术有关,该密封技术可以是各种各样的。例如,可以向条带6a、6b的接触表面中的至少一个接触表面提供粘合剂材料。在这种情况下,压辊能够促进表面的粘合。
另选地,并且如图3所示,可以提供密封工位9,从而允许将所述两个表面与条带接触地密封。该设备可以包含与对所述表面进行加压相结合的加热部件,以促进密封,例如通过热密封。应理解,温度和压力必须是适中的,以便不损坏RFID纺织纱线5(特别是它所包含的电子芯片)。
根据特别有利的变体实施方式,该密封是通过冷焊、通过超声(例如,借助于被布置在密封工位9中的一个或更多个超声焊极)来执行的。
还可以设想借助于一个或多个线缝来密封条带6a、6b。
在通过焊接进行密封的情况下,有利的是,可以在条带的边缘上形成距RFID纱线足够远的焊点或焊线,以便不会因过度加热而损坏它,如在前面的段落中已经说明的那样。还可以设想在功能化条带的切割区域处放置焊点或焊线,以使从功能化条带提取的各个标签1的条带部分2a、2b在其整个外围上被很好地密封。有利地,将至少一个这样的焊点或焊线形成在切割区域中的天线导线处,以便将天线导线保持在所述两个条带部分之间。当通过缝制进行密封时,通过提供至少部分地覆盖切口区域的线缝,也可以获得该优点。
在通过焊接(无论是热焊接还是超声焊接)进行密封的情况下,将选择至少一个条带的性质,以使其包括在低于400℃的中等温度下可熔的材料,使得当条带的温度局部且短暂地上升到高于该温度时,电子芯片3a不被暴露于可能将其损坏的过高温度。
当然可以将通过焊接的密封和/或通过施加粘合剂材料的密封和/或通过缝制的密封进行组合。
如已经提到的,条带可以是层压条带。可以在图3所示的制造方法期间执行该层压步骤。在这种情况下,例如可以在所述两个主条带被密封之前在它们之间放置从专用线轴(图3未示出)退绕的密封条带。根据所选择的密封技术,该密封条带可以具有设有粘合剂材料层或者由可熔材料制成的两个面。
在用于制造功能化条带的设备中可以设有其它工位,诸如印刷工位11和/或用于将条带切割或预切割成标签的工位。当不被切割成标签时,可以将功能化条带收集在条带线轴10上。
在该实施方式的变体中,RFID纱线没有被连续地从线轴退绕,以便被连续地插入在所述两个条带6a、6b之间。与此相反,在其包装线轴的下游紧接着设有用于切割RFID纱线的工位,以便得到该纱线的功能化节段(即,相应地包括有线电子识别器件的节段)。将所得到的节段一个接一个地插入所述两个条带6a、6b之间,这两个条带6a、6b可以连续地移动。为此,可以提供的是,使从RFID纱线切割工位得到的节段经由管道在如下插入区域中运送(可能由注入到该管道中的压缩空气射流进行辅助),即,在该插入区域中,该节段可以被这些条带6a、6b的移动捕获以便夹持在这两个条带之间。
这个实施方式是有利的,因为它允许以完全受控的方式将RFID纱线节段插入两个条带6a、6b之间。特别地,在两个节段之间可以留有足够的距离以允许密封和切割所述两个条带。在通过该方法生产的标签1中,如图1b所示,有线电子识别器件3的天线3b没有沿长度方向从标签1的一个端部延伸至另一个端部,并且该天线没有与标签的边缘相通或者没有与标签的边缘齐平。两个条带6a、6b可以在标签1的整个外周上完全密封在一起,以便极佳地封装器件3。
当寻求被集成在两个条带之间的RFID纱线采取RFID纱线条带的形式时,可以寻求将RFID纱线条带的制造步骤集成到标签的制造步骤中。如先前所陈述的,这种RFID纱线条带通常是在被切割成条带之前成行地形成在大衬底上。可以提供的是,被集成到该制造方法中并且在将衬底切割成条带之前的组装步骤用于将承载电子识别器件(或其一部分)的衬底放置在两个宽幅之间,所述两个宽幅由与已经针对条带部分2a、2b描述的材料相同的材料制成。在这种情况下,优选地借助于粘合剂材料提供具有所述两个宽幅的组件,但是在通过焊接执行这种组装的情况下,人们将寻求形成焊点以便至少部分地限定围绕电子识别器件的区域,并由此预定义标签1。一旦该组件完成,就可以将其切割成条带。
另选地,可以提供的是,将密封步骤定位在将由所述两个宽幅和衬底形成的组件切割成条带的步骤之后。在这种情况下,密封步骤和该密封之后的步骤与关于图3所述的步骤非常相似。
在该实施方式的变体中,使用单个宽幅并将其组装在承载电子识别器件的衬底的面上,然后在该变体中用衬底本身代替另一宽幅。
应注意,对于任何形式的RFID纱线,也可以实现这种导致将有线识别器件放置在两个宽幅之间的制造方法。在这种情况下,将RFID纱线的延伸区段在大宽幅中的一者上以平行的行进行布置,然后利用第二宽幅进行覆盖。然后可以沿着平行的纱线行将该组件切割成条带。
在又一实施方式中,通过在纺织条带中编织RFID纱线来形成多个电子标签。在这样的情况下,功能化条带是由被编织到纺织条带中的RFID纱线组成的。在切割条带之后,电子识别标签并入被编织到该条带的一部分中的至少一个有线电子器件。RFID纱线(可以是缠绕式类型)例如可以在其制造期间在纺织条带的经纱线之间被拉动。相反地,它可以在制造该条带之后进行集成。
非常普遍,制造电子标签1的方法因此包括以下两个步骤:
-将至少一个有线电子器件(其可以被并入到RFID纱线或RFID纱线节段中)布置在两个部件(其可以是条带、或者宽幅、或者宽幅和电子芯片的衬底)之间;
-将这两个部件密封在一起以限定至少一个电子标签。这种密封可以在将被组装至芯片衬底的宽幅切割成条带之前或者在这种切割之后来进行。它可以通过焊接、借助于粘合剂材料、通过缝制等来实现。
独立于所选择的制造技术,在制造方法的结束时,可获得功能化条带,即,其中集成了整个长度的RFID纱线或者其中集成了彼此隔开的RFID纱线节段的条带(柔性材料带,例如,窄、长且平坦的织物)。RFID纱线可以是任何类型的,例如,缠绕式、采用条带、或者甚至可以由有线电子识别器件的简单链构成。
为了获得根据本说明书的电子标签,例如通过在先前由印刷工位11或者由预切割工位形成的切割标志处撕开或切割这些节段来取下功能化条带的节段。当然,确保在RFID纺织纱线区段的条带的各个切割部分中包括完整无缺且有功能的电子识别器件(芯片和天线)。
在所有情况下,根据本说明书中描述的实施方式功能化的条带以及取自该条带的标签1具有允许它们非常容易被处理的形式和刚性因素,以便使用该工业领域中的常规设备将它们集成到产品或纺织件中。特别地,可以通过在标签的惰性区域中延伸线迹,例如在RFID纺织纱线3的一侧和/或另一侧延伸,来将标签缝制到纺织件上。
根据特别有利的方法(并且其还形成本发明本身的方面),将至少一个标签借助于缝合线缝固接至纺织件,有利地固接在该纺织件的一个边缘上。这种缝合线缝是如下线缝,即,该线缝的主要功能是处理纺织件以使其成为成品。本发明提供了利用该缝合线缝来将标签集成在其中的优点,以使至少有线电子识别器件被放置在该线缝内部。这样,利用缝线有效地保护了电子器件,并且可以非常容易地集成该电子器件。
如ISO 4915中所记载的,构成线缝的线迹在性质上可以多种多样。因此,它可以是单股暗缝线迹(根据ISO标准4915的类103)、包边线迹、缎纹或Z形线迹(类304)、覆盖线迹(类406或407)、包缝线迹(根据类500中的线迹之一)、直线迹(类301或2x301)。
在不排除其它类型的线迹的情况下,允许将标签1固接至纺织件的线缝有利地由包缝线迹形成,并且有线电子识别器件被放置在包缝线迹的线圈中/线圈下方。应记起的是,在包缝线迹中,线围绕纺织件的边缘成线圈。这些线迹在制造纺织件方面形成了用于处理该纺织件的边缘的步骤。它通常是由包边机来实施的,该包边机是织物制造设备,使得可以同时组装、后整理边缘以及切割多余的织物。它允许织物片通过包缝这些织物片的边缘来组装。这种设备设有多个针,这些针供应有来自线轴的多个纺织纱线(至少两个,有时5个或更多个),这使得可以同时缝制和包缝纺织件。它尤其允许形成摺边。它还配备有刀片以切割多余的织物。
因此,图4示出了纺织件A,根据本发明的电子识别标签1已经通过将其完全放置在包缝的线圈之间而被固接至该纺织件A。
在该图中可以看出,一方面,标签1可以借助于第一直线缝c1而保持在纺织件A中,该第一直线缝c1是由包边机的第一针形成的,并且基本上平行于RFID纺织纱线。而且,标签1(以及被包含在该标签中的RFID纱线节段)是通过由一个或更多个其它针形成的包缝的线圈c3而抵靠纺织件来保持的。
当然可以提供由其它针形成的其它线缝,例如图4中平行于第一线缝的第二线缝c2,所有这些线缝均形成包缝线迹。
为了固接标签1并实现图4所示的纺织件A,可以预先用手将标签1定位在该纺织件上,并且在包边设备的滑动脚下方滑动该组件。然而,有利地,可以提供一种附加工具,其中RFID标签在缝制操作期间被定位并引导为被集成到该线缝中。还可以提供其上安装有功能化条带(例如以线轴形式)的自动设备。然后,该设备能够移动功能化条带,将其切割,并由此限定标签,并插入该标签,以使在该标签制造过程中将其引入线缝中。
不需要将整个标签1放置在纺织件的包缝线圈之间。当这个标签带有需要在这些暴露表面中的至少一个暴露表面上可见的图案4a、4b(条形码、文本指令)时,情况尤其如此。因此,图5示出了这样的构造,即,标签1仅有一部分(特别是有线电子识别器件3)被布置在包缝的线圈之间。这确保了RFID纱线节段的良好保护和良好行为。
图6示出了制造纺织件的另一种方法,其中,标签1被放置在通过线缝C保持在一起的两个基本纺织件A1、A2之间。同样在这种情况下,至少可以提供的是,将RFID纱线放置在包缝线迹的线圈中,并且可能放置整个标签1。至少一个直线缝允许将标签固接至所述两个基本纺织件,而标签被放置在这两个基本纺织件之间。
应注意,由于电子识别器件3采用有线形式并且被精确地定位在标签1上,因此,可以容易地缝制标签1而不损坏该器件3(特别是天线3a),这对于现有技术标签,情况并非总是如此。
标签1可以以可重复、可靠且鲁棒的方式进行集成。它使用已证明的剪裁技术,并且不会产生过多的附加成本,这是因为它被集成到了先前存在的剪裁步骤中。
当然,本发明不限于所描述的实施方式,并且可以在不脱离由权利要求限定的本发明的范围的情况下,添加变体。
如已经提及,电子器件的电子芯片包括电子识别芯片不是必需的。更一般地,它可以是任何类型的电子芯片,例如,形成传感器的电子芯片,该传感器可以可选地并入被连接至天线的发射-接收功能,以便能够传送这些测量结果。另选地,它可以是具有发光功能的电子芯片。因此,从这个角度来看,并且通常地,本发明涉及一种包括被集成到条带中的有线电子器件的电子标签。
