Description

一种复合纳米纤维水刺无纺布
技术领域
本发明涉及一种纺织纤维，具体为一种复合纳米纤维水刺无纺布。
背景技术
无纺布（英文名：Non Woven Fabric 或者 Nonwoven cloth）又称非织造布，是由定向的或随机的纤维而构成。因具有布的外观和某些性能而称其为布。简单的讲就是：它不是由一根一根的纱线交织、编结在一起的，而是将纤维直接通过物理或化学的方法粘合在一起的，所以，当你拿到你衣服里的粘称时，就会发现，是抽不出一根根的线头的。一、无纺布的特点无纺布没有经纬线，剪裁和缝纫都非常方便，而且质轻容易定型。非织造布突破了传统的纺织原理，并具有工艺流程短、生产速率快，产量高、成本低、用途广、原料来源多等特点。与纺织布相比强度和耐久性较差，而且不能像其他布料一样耐清洗。因为纤维按一定方向排列，所以容易从直角方向裂开等等，因此生产方法的改善主要放在防止分裂的改良上。
发明内容
本发明的目的在于提供一种复合纳米纤维水刺无纺布，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：1.一种复合纳米纤维水刺无纺布，其特征在于，包括以下具体步骤制成：
A.将100份PP纤维、12-20份纳米纤维素纤维、2-5份聚酯纤维，按比例投入到输送平帘上，送入到粗开松机；
B.原料经过混棉充分混合后，喂入精开松机，在精开松机内进行充分开松和预梳理；
C.经过精开机的纤维通过风送管道进入到气压棉箱，保证棉层体密度一致，梳理机接收气压棉箱按照工艺设定重量给入的纤维，梳理成均匀的10-15克/平方米双层纤维网状薄层；
D. 预湿处理:双层纤维网状薄层经过夹持碳帘的握持输送，通过往复作用，使其铺网达到7—18层；
E.水刺加固:经成形的纤网送入水刺机加固，进行预加湿处理，预湿的目的是压实蓬松的纤网，排除纤网中的空气，使纤网进入水刺区后能有效地吸收水射流的能量，以加强纤维缠结效果，在水射流直接冲击和反弹水流的双重作用下，纤网中的纤维发生位移、穿插、缠结、抱合，形成无数个柔性缠结点，从而使纤网得到加固。
F.脱水：水刺工序结束后将纤网中水分降至最低，有利于降低烘燥能耗；
G.在针刺机前喂入，使纤维网在针刺前均匀的夹持喂入针区； 将经过梳理、铺网形成的纤维网通过预针刺工序将纤维网初步缠结定型，保证原纤维网的方向不变，将经过预针刺机初步缠结的纤维网通过主针刺机进一步针刺缠结，针刺5-8次，将经过主针刺加固缠结的纺粘无纺布通过修面针刺机正反两面针刺，达到成型针刺无 纺布表面平整，无毛刺、骨痕现象，经过储布张力架进行坯布储布。
纳米纤维素是一种新型的高分子功能材料，具有的结构和优良的性能，其三维纳米网状结构，生物适应性，良好的机械稳定性，抗菌性等优良性能。
与现有技术相比，本发明有以下优点：1.柔性缠结，不影响纤维原有特征，不损伤纤维。2.外观更接近传统纺织品。3.强度高，低起毛性。4.高吸湿性，快速吸湿。5.手感手软，悬垂性好。6.外观花样多变。
