Abstract
本发明涉及一种既无需热熔胶，也无需拉伸无纺布、无纺布条，便能将面层无纺布和底层无纺布或无纺布条在弹性透气膜拉伸状态下复合在弹性透气膜两面或两边，并且能够形随着弹性透气膜的回弹复位形成所需弹性透气弧形折绉式复合无纺布或折绉式防侧漏无纺布生产线及制作方法，包括PLC控制器，弹性高分子树脂流延模头下方为弹性透气流延模成型辊组，多对纵向弹性透气膜拉伸辊组横向依次分布在弹性透气流延模成型辊组一侧，复合成型辊组横向位于多对弹性透气膜拉伸辊组中末端弹性透气膜拉伸辊组一侧且复合成型辊组中辊面布满凹凸点匹配的圆形凹槽和凸点。
Description
技术领域
本发明涉及一种既无需热熔胶，也无需拉伸无纺布、无纺布条，便能将面层无纺布和底层无纺布或无纺布条在弹性透气膜拉伸状态下复合在弹性透气膜两面或两边，并且能够形随着弹性透气膜的回弹复位形成所需弹性透气弧形折绉式复合无纺布或折绉式防侧漏无纺布生产线及制作方法，主要用于医用绷带、卫生巾、纸尿裤，属复合无纺布制造领域。
背景技术
CN202213263U、名称“一种复合无纺布”，由至少一层弹性无纺布和至少一层弹性透气膜复合而成。所述弹性透气膜为聚氨酯薄膜。所述弹性无纺布和弹性透气膜藉由粘合剂复合而成。所述粘合剂为热熔胶。弹性无纺布和弹性聚氨酯透气膜在进行复合操作时均处于拉伸状态，在复合完成后自动回缩。其不足之处：一是该复合无纺布复合成型时需要弹性无纺布和弹性聚氨酯透气膜在处于拉伸状态完成复合，复合成型后的无纺布的弹性透气膜的弹性受弹性受弹性无纺布的制约，得到的是以弹性无纺布弹性为限的复合无纺布，其弹性非常有限；二是弹性无纺布与弹性聚氨酯透气膜的复合依赖于热熔胶，而热熔胶的基本树脂是乙烯和醋酸乙烯在高温高压下共聚而成的EVA树脂，而EVA树脂的粘性本身很低，需加入增粘剂，如改性松香（138或145），C5石油树脂，C9石油树脂，萜烯树脂等，这些成份的加入使得热熔胶的粘性增强，但其作为弹性无纺布与弹性聚氨酯透气膜的复合介质时，却大大堵塞了弹性无纺布的透气性，使复合成型后的复合无纺布的透气性大大降低，甚至很差。
本申请所有在先专利CN102302400 B、名称“弹力通气全腰贴及制作方法”，弹力通气全腰贴的成型设备，它包括吹膜机构，吹膜机构吹口两侧分别设有人字形成型膜导辊架且人字形成型膜导辊架出口直对弹力膜成型辊的进口，弹力膜成型辊出口直接对刀刃刃口成型辊的进口，刀刃刃口成型辊的出口直接对绉纹成型复合辊的进口，绉纹成型复合辊的出口对面是收卷辊。该设备采用吹膜机构，因而其成型膜导辊架5 、膜成型辊6、刀刃口成型辊7、绉纹成型复合辊及收卷辊均垂直设置。其不足之处：不便于无纺布在其膜面上的复合。
发明内容
设计目的：避免背景技术中的不足之处，设计一种既无需热熔胶，也无需拉伸无纺布、无纺布条，便能将面层无纺布和底层无纺布或无纺布条在弹性透气膜拉伸状态下复合在弹性透气膜两面或两边，并且能够形随着弹性透气膜的回弹复位形成所需弹性透气弧形折绉式复合无纺布或折绉式防侧漏无纺布生产线及制作方法，主要用于医用绷带、卫生巾、纸尿裤。
设计方案：为了实现上述设计目的。本发明在结构设计上：1、弹性透气膜的膜面有很多透气孔的设计，是本发明的技术特征之一。这样设计的目的在于：由于本发明所述弹性透气膜与无纺布的复合为无胶（无热熔胶）复合，即弹性透气膜的膜面与无纺布直接热压复合。为此本发明将所成型的弹性流延膜面设计为开孔的弹性透气膜面，这样设计的目的在于：开孔弹性透气膜面不仅能够使本不透气的弹性膜变成透气膜，而且很多个透气孔分布在弹性膜面使弹性膜面拉伸率则增大，弹力增强、伸缩率增大，所制的医用绷带具有平整度好、伸缩率大、弹性好、透气性好且价格低。其次，它能够它取代目前纸尿裤裤裆裆部防侧漏采用橡筋制作所带来的制造设备复杂、制作工艺复杂、成本高，效率低，以及采用胶粘剂定位橡筋所导致弹力下降、透气性差、手感生硬、舒适性差的缺陷。2、带有很多透气孔的弹性透气膜在拉伸状态下与面层无纺布和底层无纺布热复合的设计，是本发明的技术特征之二。这样设计的目的在于：一是由于面层无纺布和底层无纺布的弹性非常小，基本上可以忽略不计，根本无法在拉伸状态下与弹性膜复合。为此，本发明将弹性膜制成膜面布满近似圆孔弹性透气膜，该弹性透气膜在拉伸的状态下与未拉伸的面层无纺布和未拉伸的底层无纺布热复合后，弹性透气膜回弹复位强制带动面层无纺布和底层无纺布形成弹性凹弧形折绉式复合无纺布，开创了卫生巾贴面和纸尿裤裤裆贴面凹弧形面的先例；二是将未拉伸的无纺布条复合在拉伸后的布满近似圆孔的弹性透气膜两边，弹性打孔透气膜回弹复位强制带动其两边的无纺布条回弹复位形成防侧漏侧壁，该防侧漏侧壁取代了现有卫生巾、纸尿裤裆面采用橡筋拉伸无纺布防侧漏，使卫生巾、纸尿裤防侧漏工艺得到根本性简化，大大降低了制造成本。3、弹性透气膜中透气孔的口沿采用负压抽吸所形成的凸台口结构的设计，是本发明的技术特征之三。这样设计的目的在于：弹性透气膜中透气孔口沿呈凸台口结构，就犹如在弹性透气膜面有很多个孔形口凸台支撑，该孔形口凸支撑的孔口端部与底层无纺布面热复合，使得底层无纺布面与弹性透气膜之间形成孔口部复合，不仅大大地减少了底层无纺布面与弹性透气膜的复合面积，而且使底层无纺布面与弹性透气膜之间形成多路且路路相通的中空多点支撑，透气性极佳，伸缩弹性好，开创造中空多点支撑通透复合无纺布的先例。4、多对弹性透气膜拉伸辊组依次横向分布在弹性透气流延模成型辊组一侧，复合成型辊组横向位于多对弹性透气膜拉伸辊组中末端弹性透气膜拉伸辊组一侧的设计，是本发明的技术特征之四。这样设计的目的在于：横向设置弹性透气膜拉伸辊组和弹性透气流延模成型辊组，既能够避免垂直设置所带来的地球引力对弹性膜吸力所导致的弹性透气膜厚度不均现象的出现，又能在弹性透气膜拉伸的同时方便地实现弹性透气膜单面或双面与无纺布的热压复合。5、弹性透气流延模成型辊组中光辊面置有一层耐高温防粘纳米涂层的设计，是本发明的技术特征之五。这样设计的目的在于：由于制作弹性膜的高弹性高分子树脂粒子在熔融状态下，粘性相对比较大、温度比较高，极易发生粘辊和粘连现象，不利于弹性透气膜的成型。本发明将弹性透气流延模成型辊组中光辊设计成耐高温防粘纳米辊，不仅避免了高弹性高分子树脂粒子在熔融状态下与光辊粘结或粘连现象的发生，而且满足了耐高温的需求，使初步成形的弹性透气膜的品质得到了保证。6、弹性透气流延模成型辊组负压打孔辊辊面布满负压抽吸孔口的设计，是本发明的技术特征之六。这样设计的目的在于：由于布满负压打孔辊辊面负压抽吸孔口通过各自的流道与负打孔辊内负压腔连通（负压腔通过管道与负压源连接），负压抽吸孔口在负压气流的作用下将通过负压打孔辊辊面上的弹性膜的膜面抽吸成布满透气孔的弹性膜面且透气孔的孔口背面孔口沿凸起高于膜面，从而形成负压打孔弹性透气膜。7、弹性透气膜拉伸辊组中光辊和胶辊辊面分别涂有一层耐高温防粘纳米涂层的设计，是本发明的技术特征之七。这样设计的目的在于：光辊设计成耐高温防粘纳米辊，不仅解决了高弹性高分子树脂粒子在熔融状态下与光辊粘结或粘连现象的发生，而且满足了耐高温的需求，使初步形成的弹性透气膜的品质得到了保证；而胶辊辊面采用弹性耐高温防粘层使胶辊的辊面不仅要防粘，而且要具有良好附着性，确保对弹性透气膜拉伸系数的相对一致性。8、弹性透气膜拉伸辊组中内置电加热管及温度传感器的设计，是本发明的技术特征之八。这样设计的目的在于：由于本发明中的无纺布与弹性透气膜之间的复合不采用热熔胶，而是利用弹性透气膜膜面与无纺布复合热压复合，因此确保弹性透气膜在拉伸过程中的膜面温度至关重要，为此本发明在光辊和胶辊内置入电加热管及温度传感器，该温度传感器将时时采集到的温度数据传输到PLC控制器且与内置在PLC控制器的弹性透气膜膜面的热粘接数据进行比对，进而控制光辊和胶辊内电加热管的工作温度，使弹性透气膜在与无纺布复合前处于热压粘连的温度状态，从而确保了弹性透气膜膜单面或两面与无纺布之间的可靠热压复合。9、复合成型辊组中凹凸辊和凸凹辊辊面分别涂有一层耐高温防粘弹性纳米涂层的设计，是本发明的技术特征之九。这样设计的目的在于：由于复合成型辊组中的凹凸辊和凸凹辊既具有传送拉伸弹性透气膜的功能，又具有将拉伸状态下弹性透气膜与无纺布复合的功能，因此它不仅具有防粘和附着性强的特点，而且具有保温热压复合的功能。为此本发明将其辊面上设置一层耐高温、防粘、弹性纳米涂层，该耐高温、防粘、弹性纳米涂层由于具有耐高温、防粘结、附着性好的特点，因而确保了其对弹性透气膜拉伸状态不改变的前提下，又防止了弹性透气膜与辊面的粘结，实现了无纺布与弹性透气膜之间的弹性热压复合，确保了复合后的无纺布面的手感的舒适度不改变；而设置在凹凸辊和凸凹辊内的电加热管及温度传感器通过PLC控制器对其温度数据的采集与控制，由于PLC控制器内置有弹性透气膜热压粘接温度参数且通过对弹性透气膜拉伸辊组温度采集和比对，控制弹性透气膜拉伸辊组的温度在弹性透气膜热压粘接温度的范围内变化，从而使复合成型辊组的复合温度处于最佳的设定范围内。10、弹性透气流延模成型辊组弹性透气膜拉伸辊组上设有转速传感器的设计，是本发明的技术特征这十。这样设计的目的在于：由于位于弹性透气流延模成型辊组和弹性透气膜拉伸辊组的转速受控于PLC控制器，PLC控制器通过对弹性透气流延模成型辊组和弹性透气膜拉伸辊组上转速传感器数据的采集，与PLC控制器内置弹性透气膜拉伸率与弹性透气膜拉伸辊组转速相对应的检测控制软件包比对，即可对弹性透气流延模成型辊组和弹性透气膜拉伸辊组的转速差时时控制，从而确保所需弹性透气膜的拉伸率控制在所设定的范围内。

技术方案2：一种弹性透气弧形折绉式复合无纺布制作方法，弹性高分子树脂粒子经弹性高分子树脂流延模头流延成弹性膜，弹性膜经由弹性透气流延模成型辊组导出后形成膜面布有很多透气孔的弹性打孔透气膜，弹性打孔透气膜经多对弹性透气膜拉伸辊组的S形纵向拉伸后与位于弹性打孔透气膜两面的未拉伸的底层无纺布和未拉伸的面层无纺布同时进入复合成型辊组热压复合成型导出后，位于弹性打孔透气膜两面的面层无纺布和底层无纺布随弹性打孔透气膜的回弹复位形成弹性透气弧形折绉式复合无纺布。

本发明与背景技术相比，一是无需热熔胶，无需拉伸无纺布，即实现弹性透气膜单面或双面与无纺布、无纺布条的热压复合，并且热压复合后得到所需的弧形折绉式形状，或弧形防侧漏式形状，开创卫生巾、纸尿裤裤裆防侧漏侧壁无需橡筋的先例；二是弹性透气流延模成型辊组中光辊耐高温防粘纳米涂层的设计，不仅解决了高弹性高分子树脂粒子在熔融状态下与光辊粘结或粘连现象的发生，而且满足了耐高温的需求；三是弹性透气膜拉伸辊组中光辊和胶辊辊面分别涂有一层耐高温防粘纳米涂层的设计，既防粘，又确保了对弹性透气膜拉伸系数的相对一致性；四是弹性透气膜拉伸辊组中内置电加热管及温度传感器的设计，确保了弹性透气膜膜在与无纺布热压复合所需温度连，实现了弹性透气膜膜单面或两面与无纺布之间的可靠复合，以及复合后弹性透气弧形折绉式复合无纺布的诞生；五是复合成型辊组复合辊面分别涂有一层耐高温防粘弹性纳米涂层的设计，实现了对无纺布与弹性透气膜之间的弹性压接复合，确保了复合无纺布面的手感的舒适度不改变；六是弹性透气流延模成型辊组弹性透气膜拉伸辊组、上设有转速传感器的设计，保所需弹性透气膜的拉伸率控制在所设定的范围内；七是开孔弹性透气膜的设计，不仅使弹性膜具有透气的功能，而且使弹性膜拉伸率大大地增大，具有高弹力、大拉伸率的特点。
