Description

一种结构稳定式无纺布及其制备方法
技术领域
本发明涉及一种结构稳定式无纺布及其制备方法。
背景技术
无纺布是一种非织造布，它是直接利用高聚物切片、短纤维或长丝将纤维通过气流或机械成网，然后经过水刺，针刺，或热轧加固，最后经过后整理形成的无编织的布料。具有柔软、透气和平面结构的新型纤维制品，优点是不产生纤维屑；但是目前在无纺布使用的某些领域，需要提高耐磨性以及提高结构的强度，一般是直接在无纺布的表面进行涂刷附着耐磨涂层，但是如此结构的耐磨涂层与无纺布连接的结构强度和稳定性不高，另外同时需要提高透气排湿性能。
发明内容
针对上述现有技术的不足之处，本发明解决的问题为：提供一种结构稳定、耐磨性好、结构强度高、透气排湿性能好的结构稳定式无纺布及其制备方法。
为解决上述问题，本发明采取的技术方案如下：
一种结构稳定式无纺布，包括无纺布芯层、骨架捻合纤维丝、表面涂层；所述无纺布芯层上表面依次均匀向上聚拢形成多个连接凸起条；所述多个连接凸起条从左向右依次均匀分布；所述多个连接凸起条平行设置；所述连接凸起条下侧分别对应设有一个连接条形凹槽；所述多个连接凸起条和多个连接条形凹槽通过多个骨架捻合纤维丝进行穿接；所述无纺布芯层和骨架捻合纤维丝的上下两侧面均设有表面涂层；所述表面涂层包括的组分以及重量份如下：聚丙烯粉100份、硅胶5至10份、聚四氟乙烯粉10至15份、亚麻纤维粉5至10份；所述骨架捻合纤维丝为竹纤维丝和氨纶弹性纤维丝捻合而成。
进一步，所述多个连接凸起条的截面呈弧形结构。
进一步，所述无纺布芯层为涤纶或者丙纶材质。
进一步，表面涂层包括的组分以及重量份如下：聚丙烯粉100份、硅胶7份、聚四氟乙烯粉13份、亚麻纤维粉7份。
一种结构稳定式无纺布的制备方法，步骤如下：
S1、无纺布芯层聚拢：将无纺布芯层上表面依次均匀向上聚拢形成多个连接凸起条，并且连接凸起条下侧分别对应设有一个连接条形凹槽；
S2、穿接骨架捻合纤维丝：首先在竹纤维丝表面螺旋缠绕氨纶弹性纤维，形成骨架捻合纤维丝；通过多个骨架捻合纤维丝将多个连接凸起条和多个连接条形凹槽依次进行穿接；使得多个连接凸起条和多个连接条形凹槽结构形成定位；所述骨架捻合纤维丝为竹纤维丝；
S3、配置表面涂层浆料：将聚丙烯粉、硅胶、聚四氟乙烯粉、亚麻纤维粉按照配比充分混合，然后加入纯净水进行充分搅拌，形成表面涂层浆料；
S4、涂刷表面涂层浆料：在步骤S2中的骨架捻合纤维丝与无纺布芯层的两侧面上分别涂刷表面涂层浆料；使得多个连接凸起条和多个连接条形凹槽上均填充表面涂层浆料；
S5、冷却固化：将骨架捻合纤维丝与无纺布芯层外侧附着的表面涂层浆料进行冷却固化、定型，最终得到所述的结构稳定式无纺布。
进一步，所述步骤S3中，表面涂层浆料中的水料重量比为1:8至1:10。
本发明的有益效果
1.本发明的骨架捻合纤维丝是在竹纤维丝表面螺旋缠绕氨纶弹性纤维形成，由于氨纶弹性纤维的弹性特性，当随着竹纤维丝穿接于多个连接凸起条和多个连接条形凹槽后，氨纶弹性纤维会弹性紧绷穿接于多个连接凸起条上，如此使得无纺布芯层的多个连接凸起条的结构处于被弹性紧绷扩张的趋势中，进而使得无纺布芯层的多个连接凸起条的结构更加稳定。
2.本发明改变了传统直接在无纺布芯层的两侧涂刷耐磨层的方式和结构，本发明利用凸起来增加粘接面积，但是无纺布表面进行粘接凸起条起不到很好的粘接效果，如此本明从无纺布芯层的本身出发设计，利用无纺布的柔软特性将无纺布芯层的上表面依次均匀向上聚拢形成多个连接凸起条，并且连接凸起条下侧分别对应设有一个连接条形凹槽，如此从无纺布本身出发形成无纺布上下两侧的凹凸不平的曲面结构，极大提高了表面涂层与无纺布的连接结构强度；本发明通过多个骨架捻合纤维丝将多个连接凸起条和多个连接条形凹槽依次进行穿接，如此使得多个连接凸起条和多个连接条形凹槽结构形成定位便于后续涂附表面涂层浆料，同时多个骨架捻合纤维丝起到加强筋的作用，提高了整个结构强度和韧性。
3.本发明利用无纺布的柔软特性将无纺布芯层的上表面依次均匀向上聚拢形成多个连接凸起条，如此将无纺布进行纵向延伸，极大的拓展了无纺布在纵向的面积，如此提升了整个结构的透气排湿截面，进而极大的提升了透气排湿性。

S5、冷却固化：将骨架捻合纤维丝1与无纺布芯层外2侧附着的表面涂层浆料进行冷却固化、定型，最终得到所述的结构稳定式无纺布。
本发明的骨架捻合纤维丝1是在竹纤维丝表面螺旋缠绕氨纶弹性纤维形成，由于氨纶弹性纤维的弹性特性，当随着竹纤维丝穿接于多个连接凸起条21和多个连接条形凹槽22后，氨纶弹性纤维会弹性紧绷穿接于多个连接凸起条21上，如此使得无纺布芯层的多个连接凸起条21的结构处于被弹性紧绷扩张的趋势中，进而使得无纺布芯层2的多个连接凸起条21的结构更加稳定。
本发明改变了传统直接在无纺布芯层2的两侧涂刷耐磨层的方式和结构，本发明利用凸起来增加粘接面积，但是无纺布表面进行粘接凸起条起不到很好的粘接效果，如此本明从无纺布芯层2的本身出发设计，利用无纺布的柔软特性将无纺布芯层2的上表面依次均匀向上聚拢形成多个连接凸起条21，并且连接凸起条21下侧分别对应设有一个连接条形凹槽22，如此从无纺布本身出发形成无纺布上下两侧的凹凸不平的曲面结构，极大提高了表面涂层与无纺布的连接结构强度；本发明通过多个骨架捻合纤维丝1将多个连接凸起条21和多个连接条形凹槽22依次进行穿接，如此使得多个连接凸起条21和多个连接条形凹槽22的结构形成定位便于后续涂附表面涂层浆料，同时多个竹纤维的骨架捻合纤维丝1起到加强筋的作用，提高了整个结构强度和韧性。
本发明利用无纺布的柔软特性将无纺布芯层的上表面依次均匀向上聚拢形成多个连接凸起条21，如此将无纺布进行纵向延伸，极大的拓展了无纺布在纵向的面积，如此提升了整个结构的透气排湿截面，进而极大的提升了透气排湿性。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
