针对现有技术的不足，本发明提供了一种含PHBV材料抗菌抗病毒防霉涤纶水刺无纺布的制备方法，解决了上述背景技术中提出的问题。
(二)技术方案
为实现以上目的，本发明通过以下技术方案予以实现：一种含PHBV材料抗菌抗病毒防霉涤纶水刺无纺布的制备方法，包括由PET纤维与PHBV粒料混合纺丝成的禾合涤纶纤维，再将禾合涤纶纤维和粘胶纤维两者通过水刺无纺工艺加工成型，具体如下步骤：
步骤一：准备PET和PHBV材料；
步骤二：在PET纺丝阶段加入干燥的颗粒原料PHBV，采用具有两组同轴导丝孔的皮芯型复合喷丝板的纺丝机进行混合纺丝成禾合涤纶纤维；
步骤三：步骤二中的禾合涤纶纤维与粘胶纤维，采用小定量的方式喂入梳理机梳理成纤维网；
步骤四：将步骤三的纤维网送入水刺机，利用水刺机对其进行水刺加工形成水刺布，并进行真空抽吸处理，同时利用烘干设备的热风回收***向所述水刺布输送热风烘干，最后通过卷绕机将烘干后的水刺布卷成布卷，按要求对布卷分切后进行包装。
优选的，制成的含PHBV材料抗菌抗病毒防霉涤纶水刺无纺布，应用于纱线、面料、服装服饰、医疗卫生用品、家纺产品。
优选的，步骤二中的混合纺丝的方法如下，在PET纺丝阶段加入干燥的颗粒原料PHBV，经过螺杆挤出机挤出，并将挤出机温度控制在200～260℃，使得PHBV在这个温度范围内熔化并降解成低聚合度物质。
优选的，按重量份为PET纤维90～99，PHBV粒料1～10进行配比混纺。
优选的，步骤三中采用30～45g/m 2的小定量方式喂入梳理机。
(三)有益效果
采用上述技术方案后，本发明与现有技术相比，具备以下优点：本发明一种含PHBV材料抗菌抗病毒防霉涤纶水刺无纺布的制备方法，结合低聚合度丁酸戊酸脂(PHBV)破坏细菌等微生物的细胞壁和病毒的胞膜的杀菌灭毒原理，将其按一定比例添加到PET里面纺丝后做成禾合涤纶短纤，赋予纤维非溶出抗菌性能，并采用水刺无纺布工艺将禾合涤纶纤维和粘胶纤维按一定混比制成涤纶水刺无纺布，使其抗菌抑菌等性能得到充分的体现，同时具有长效抗菌抗病毒功能，能够广泛应用于各类纱线、面料、服装服饰、医疗卫生用品、家纺产品等。
具体实施方式
下面具体实施例对本发明作进一步详细阐述。
一种含PHBV材料抗菌抗病毒防霉涤纶水刺无纺布的制备方法，包括由PET纤维与PHBV粒料混合纺丝成的禾合涤纶纤维，再将禾合涤纶纤维和粘胶纤维两者通过水刺无纺工艺加工成型，制成的含PHBV材料抗菌抗病毒防霉涤纶水 刺无纺布。
具体如下步骤：
步骤一：准备PET和PHBV材料；
步骤二：在PET纺丝阶段按重量份为PET纤维90～99，干燥PHBV粒料1～10加入进行配比混纺，采用具有两组同轴导丝孔的皮芯型复合喷丝板的纺丝机进行混合纺丝成禾合涤纶纤维；
步骤三：步骤二中的禾合涤纶纤维与粘胶纤维，采用38g/m 2的小定量方式喂入梳理机梳理成纤维网；
其中混合纺丝的方法如下，在PET纺丝阶段加入干燥的颗粒原料PHBV，经过螺杆挤出机挤出，并将挤出机温度控制在220℃，使得PHBV在这个温度范围内熔化并降解成低聚合度物质。
步骤四：将步骤三的纤维网送入水刺机，利用水刺机对其进行水刺加工形成水刺布，并进行真空抽吸处理，同时利用烘干设备的热风回收***向所述水刺布输送热风烘干，最后通过卷绕机将烘干后的水刺布卷成布卷，按要求对布卷分切后进行包装。
