Description

一种带状织物的加工方法 技术领域
本发明属于带状织物领域，带状织物包括口罩带以及各种服装用带状辅料，其具有一定宽度，一般在2.5-200mm，呈长条带状，具体涉及一种带状织物的加工方法。
背景技术
带状织物作为纺织服行业重要的辅料，在服装、医用以及安全防护用途上具有广泛的用途，虽其用途广泛，但其带状织物的实现途径上，主要是在专用带状织物编织设备上编织，根据其用途，一般编织宽度在2.5-200mm宽度之间，由于其带状织物宽度一般比较窄，无法通过常规面料的染色机和定型机进行染色和定型以及后整理，目前带状织物主要是通过两种加工方法来进行后整理及染色。第一种加工方法是先进行编织，后在连续扎染机上染色烘干，缺点一是通过连续扎染机进行染色时，只能常温染色，对于那些需要高温染色的纱线则受到很大限制，缺点二是连续扎染机每次能够连染的带状织物根数有限，效率较低。第二种加工方法是纱线先染色后再进行编织，缺点一是纱线染色要先进行倒筒、纱染、络筒工序，流程长、效率低，成本高，尤其是一条带状织物有多种原料组成时，需要分别对每种原料染色，不能同时染色。缺点二是纱线先染色后编织带状织物，纱线颜色均匀性控制难度高于先编织后染色的方法，尤其是单纤细度低于0.5旦尼尔的纱线，纱线染色难度大、颜色均匀性差。以上两种加工方法在进行带状织物热定型或者烘干时，一般多条带状织物同时进行烘干，同时保证每根带状织物的张力一致难度较大，尤其弹性带状织物，更加容易造成带状织物弹力不一致的现象。
发明内容
本发明的目的是克服现有技术中的一个或多个不足，提供一种新的带状织物的加工方法，该方法创新地优先制备特定的经编面料，此经编面料可在带状织物分离前利用服装面料的染整设备(例如溢流染色机)进行染色和定型，使其结构稳定后再进行带状织物的可分离操作，也即间接实现了可同时编织多根结构稳定且能够染色的带状织物的目的，且此带状织物的宽度在不更换设备的前提下可调。
为达到上述目的，本发明采用的一种技术方案是：
一种带状织物的加工方法，所述加工方法包括如下步骤：
(1)制备可分离成带状织物的经编面料，所述经编面料采用经编编织而成；其中，所述经编面料包括至少一个可消解单元、至少两个经编编织单元，两两相邻所述经编编织单元之间通过所述可消解单元连接，所述的经编编织单元为由至少一种纱线沿经向编织而形成的带状织物，所述可消解单元由能够通过物理和/或化学方法消解的可消解连接纱线沿经向编织而成；
(2)将制成的所述经编面料与底布上下叠加固定；
(3)将经步骤(2)处理后的经编面料通过物理和/或化学方法消解所述可消解连接纱线，获得至少两根且分别独立地叠加固定在所述底布上的所述带状织物，然后使所述带状织物与所述底布相分离。

根据本发明的一些优选且具体的方面，所述带状织物为口罩耳带或各种服装用的带状辅料。进一步地，可以根据带状织物的不同用途，在编织带状织物部分时使用弹性纱线，使带状织物具有良好的弹性和回复性，特别适合用作口罩类耳带和领口、袖口、弹性腰带及有弹性需求的各种带状服装辅料。
根据本发明，根据带状织物的应用场景不同，可通过调整编织带状织物的纱线根数来调节其宽度，其带状织物最小宽度可在1.5mm。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
(1)与目前带状织物的主要编织方式不同，此编织方式是先在经编机上编织成一定宽的面料，通过后整理后将较宽的面料分离若干较窄的带状织物，此编织方式编织的经编面料可分离的带状织物更多，产量更高、经济效益更加明显。
具体地，以经编机机号为28针，工作幅宽为218英寸的三梳经编机编织3mm宽度的口罩耳带为例，4根经纱可以编织一根3mm宽度口罩耳带，一台经编机可以最 多穿6000根经纱，同时编织的面料可以最多分离成1500根独立的口罩耳带，而编织速度最快可以达到2800转/分，以编织密度为15个线圈/厘米，设备正常运行效率为90％为例，每24小时可产面料2688米，经过染色定型后面料密度为35个线圈/厘米，面料可分离的口罩耳带总长度为172.8万米，以每个口罩使用0.35米耳带计算，此编织方法形成的口罩耳带每天可产满足493万个口罩的使用量。
(2)利用纱线不同化学或者物理性能的差异设计，特别是利用不同化学或者物理性能纱线和织物结构设计组合，使特定区域的纱线在后整理过程中溶解，而使面料分离成若干根带状织物，特定区域纱线溶解前经编面料可以在常规染色设备和定型机上染色和定型，后整理操作更方便、设备通用性更高，克服了常规带状织物先纱线高温染色后编织或先编织后通过连续扎染机常温染色定型的效率低、成本高的缺点；
(3)可根据设计要求，在不增加任何辅助设备的情况下，只需改变穿纱工艺来改变形成带状织物的纱线根数，即可完成不同宽度带状织物的改变，操作更方便，也可以通过穿纱工艺的改变，同时编织不同宽度的带状织物。
(4)本发明制成的带状织物，在溶解两相邻带状织物之间的连接纱时，同时对纱线表面油污进行去除，在特定使用场景下更加干净卫生，如一次性口罩耳带，目前主要采用的工艺流程是编织后直接使用，没有经过水洗去污去油工艺。存在一定的卫生风险。
(5)本发明制成的带状织物当含有氨纶弹力纤维时，在染色和后整理过程中，可以主动调节织物的经向张力，可以根据弹力要求对带状织物的弹性进行精确控制。
(6)相比于传统带状织物只能以独立的带状形式在连续扎染机上常温染色(如果采用溢流染色机染色，由于染色前是独立的带状形式，则极易使得各带状织物之间发生缠解，且容易造成染色不均)，本发明是可分离成带状织物的经编面料在带状织物间连接纱溶解前以面料的形式采用高温高压溢流染色机染色，染色方法不仅可以常温染色，也可以高温染色，对需要高温染色的纱线，传统带状织物的加工方法是先纱线染色，后带状织物编织，本发明可以对带状织物高温染色，克服了传统带状织物先编织后染色的原料选择限制。
(7)相比于传统带状织物只能在连续扎染机上染色，每次进行染色的根数有限，染色效率低；本发明方法使带状织物可在用于面料染色的溢流染色机上染色，每次进行染色的数量更多，染色效率更高、成本更低。
(8)相比于传统带状织物在连续扎染机上染色和烘干时每条带状织物的张力单独控制，张力均匀性控制难度大，本发明方法中对可分离成带状织物的经编面料在精炼预缩后通过高温定型时整幅面料内若干带状织物张力同时控制，带状织物张力控制更均匀、控制精度更高、控制难度更低。
(9)对于需要高温染色的纱线，传统带状织物获得颜色的方法是先进行纱线染色，后进行编织带状织物，对单纤细度低于0.5旦尼尔的纱线，染色难度大，染色均匀性差，本发明采用直接对可分离成带状织物的经编面料染色，使得分离后的带状织物颜色均匀性更好，色差更小。

  11. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(1)中，两两相邻所述经编编织单元之间有且仅由所述可消解单元连接。
  12. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(1)中，所述可消解连接纱线在相邻织针或间隔多针间以交替成圈或者衬纬形式编织连接相邻所述带状织物。
  13. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(1)中，所述可消解连接纱线独立地卷绕在一组经轴上，然后独立地穿在一把导纱梳栉上；或，所述可消解连接纱线与编织所述带状织物的其中一种所述纱线卷绕在同一组经轴上，然后共同穿在同一把导纱梳栉上，所述的同一把导纱梳栉需满足在相邻织针或间隔多针间以交替成圈或者衬纬形式编织来连接相邻所述带状织物。
  14. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(1)中，编织所述带状织物的所述纱线为聚酯纤维和/或聚酰胺纤维，或，氨纶纤维与聚酯纤维和/或聚酰胺纤维的组合。
  15. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(1)中，所述可消解连接纱线为碱溶性聚酯纱线。
  16. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(2)中，所述上下叠加固定的方法是沿着所述经编面料的长度或宽度方向通过缝纫方式等间隔地将所述经编面料与所述底布缝纫固定。
  17. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(3)中，所述物理和/或化学方法包括碱减量处理。
  18. 根据权利要求5所述的带状织物的加工方法，其特征在于，步骤(3)中，在所述分离之前，还包括对叠加固定在所述底布上的所述带状织物进行烘干的步骤。
