Description
技术领域
本发明涉及生理卫生用品技术领域,特别涉及一种抑菌防漏型吸收物品及其制造方法。
背景技术
随着时代的发展,消费者对卫生吸收用品的要求不断提高,要求卫生吸收用品同时具备瞬吸、瞬干、柔软、透气、抑菌、舒适等性能。然而,当前市面上的大部分吸收物品吸液后依旧存在下渗速度慢、吸收性差、侧漏、干爽性差等问题,因此需要研发一种下渗速度快、吸收性好、干爽性好、能有效防止侧漏且抑菌祛味效果好的吸收物品。
发明内容
本发明提供了一种抑菌防漏型吸收物品及其制造方法,一种下渗速度快、吸收性好、干爽性好、能有效防止侧漏且抑菌祛味效果好的吸收物品。
本发明在第一方面提供了一种抑菌防漏型吸收物品,所述抑菌防漏型吸收物品包括由上至下依次设置的透液性表层、超导吸收结构和透气底层;
所述超导吸收结构包括超导结构和设置于所述超导结构中部的吸收结构;
所述吸收结构高于所述超导结构。
优选地,所述透液性表层为抑菌水刺无纺布;
所述抑菌水刺无纺布由芦荟粘胶纤维、壳聚糖纤维和竹炭纤维复合得到。
优选地,所述抑菌水刺无纺布中各成分的百分含量为:芦荟粘胶纤维5~10wt%、壳聚糖纤维20~35wt%和竹炭纤维60~70wt%。
优选地,所述超导结构为由两层湿法造高吸水树脂吸水纸的宽度方向的两端朝向透液性表层的方向翻折形成的开放结构;所述开放结构包括两个翻折部分和连接所述翻折部分的中心部分的开放结构;所述翻折部分远离所述中心部分的两端形成所述超导结构的开放端;
所述超导结构的中心部分的长度为10~18cm,宽度为6~8cm。
优选地,所述翻折部分与所述中心部分的夹角为a,0°≤a≤165°;
优选的是,当0°≤a<90°时,所述翻折部分靠近开放端的区域设置有通孔,更优选的是,在所述翻折部分靠近开放端三分之一的区域设置有通孔;
所述通孔的孔径为0.1~0.3mm。
优选地,所述吸收结构为由一层湿法造高吸水树脂吸水纸折叠而成的中凸小芯;
所述吸收结构的长度为6~10cm,宽度为3~5cm,高度为4~7mm。
优选地,所述吸收结构比所述超导结构的开放端高1~3mm;
所述吸收结构与所述超导结构的开放端之间存在缝隙。
优选地,所述湿法造高吸水树脂吸水纸为通过湿法造纸将高吸水树脂均匀分布在两层原纸层之间复合得到;其中各成分的含量为:原纸60~90wt%,高吸水树脂颗粒10~40wt%;
所述湿法造高吸水树脂吸水纸的克重为20~300g/m2,优选的是,所述湿法造高吸水树脂吸水纸的克重为70~150g/m2。
优选地,所述透气底层为PE透气底膜。
本发明在第二方面提供了上述第一方面所述的抑菌防漏型吸收物品的制造方法,所述制造方法包括:
(1)在超导结构的中部复合吸收结构得到超导吸收结构;
(2)在所述吸收结构的上层复合透液性表层,在所述超导结构的下层复合透气底层,得到所述抑菌防漏型吸收物品。
本发明与现有技术相比至少具有如下有益效果:

根据一些优选的实施方式,所述透液性表层11为抑菌水刺无纺布;

当超导结构的翻折部分与中心部分的夹角90°≤a≤165°时,翻折部分与吸收结构在长度方向上形成两条较宽的通道,不需要设置通孔;液体通过透液性表层后直接下渗到吸收结构和超导结构,并被快速吸收,同时翻折部分高于中心部分,也具有防止侧漏的作用。
当超导结构的翻折部分与中心部分的夹角0°<a<90°时,翻折部分的开放端与吸收结构中间存在缝隙,翻折部分靠近开放端的区域设置有通孔,特别是在靠近开放端三分之一的区域设置有通孔,液体可以通过透液性表层后可以通过缝隙和翻折部分靠近开放端位置的通孔快速下渗到超导结构的中心部分,并快速被超导吸收结构吸收;靠近中心部分的翻折部分与吸收结构之间沿长度方向上形成两条通道,引导液体沿吸收物品的长度方向流动,可以有效防止侧漏,同时靠近中心部分的翻折部分也能有效防止测漏;
当a=0°时,即翻折部分叠在中心部分的上面,液体通过透液性表层后直接下渗到吸收结构和超导结构,同时在靠近开放端三分之一的区域设置有通孔能加快液体下渗,此外,翻折部分与吸收结构在长度方向上也能形成两条通道,引导液体沿吸收物品的长度方向流动,可以有效防止侧漏,同时翻折部分高于中心部分也具有一定防止侧漏的作用;

所述吸收结构12的长度为6~10cm(例如,可以为6cm、6.5cm、7cm、7.5cm、8cm、8.5cm、9cm、9.5cm或10cm),宽度为3~5cm(例如,可以为3cm、3.2cm、3.4cm、3.8cm、4cm、4.2cm、4.4cm、4.6cm、4.8cm或5cm),高度为4~7mm(例如,可以为4mm、4.2mm、4.4mm、4.8mm、5mm、5.2mm、5.4mm、5.6mm、5.8mm、6mm、6.2mm、6.4mm、6.6mm、6.8mm或7mm)。
需要说明的是,吸收结构为由一层湿法造高吸水树脂吸水纸至少折叠两次而成的中凸小芯结构;
根据一些优选的实施方式,所述吸收结构12比所述超导结构的开放端高1~3mm(例如,可以为1mm、1.2mm、1.4mm、1.8mm、2mm、2.2mm、2.4mm、2.6mm、2.8mm或3mm);
所述吸收结构12与所述超导结构13的开放端之间存在缝隙。
本发明的超导结构的为翻折的开放结构,该超导结构的开放端与吸收结构存在缝隙,该缝隙可以使液体通过透液性表层之后快速下渗;超导结构与吸收结构在长度方向上形成两条通道,当液体通过透液性表层下渗到超导结构时能引导液体沿吸收物品的长度方向流动,可以有效防止侧漏;同时超导结构为两层具有高吸收性能的湿法造高吸水树脂吸水纸,可以快速吸收下渗的液体,保持表层干爽;此外,翻折的超导结构具有防侧漏的作用。
本发明超导吸收结构中吸收结构高于超导结构的开放端,吸收结构能第一时间快速吸收部分液体,翻折的超导结构也为液体下渗提供更多的空间,可以保证液体快速下渗,促进吸收结构吸收下渗的液体,保持表层干爽,同时吸收结构高于超导结构的开放端使得吸收结构能更好的贴合人体,快速吸收液体。
根据一些优选的实施方式,所述湿法造高吸水树脂吸水纸为通过湿法造纸将高吸水树脂均匀分布在两层原纸层之间复合得到;其中各成分的含量为:原纸60~90wt%,高吸水树脂颗粒10~40wt%;
所述湿法造高吸水树脂吸水纸的克重为20~300g/m2,优选的是,所述湿法造高吸水树脂吸水纸的克重为70~150g/m2。
需要说明的是,所述湿法造高吸水树脂吸水纸为通过湿法造纸将高吸水树脂均匀分布在两层原纸层之间复合得到,具体为:1)通过湿法造纸制作上、下层原纸;2)将高吸水树脂颗粒均匀撒播在下层原纸上;其中,原纸和高吸水树脂颗粒的百分含量为:原纸60~90wt%,高吸水树脂颗粒10~40wt%;3)将上层原纸与撒播有高吸水树脂颗粒的下层原纸进行压合得到复合纸;4)将压合后的复合纸经105~120℃干燥、定型得该湿法造高吸水树脂吸水纸。
本发明采用上述百分含量的原纸和高吸水树脂颗粒制备湿法造高吸水树脂吸水纸柔软舒适,吸收性能好,干爽性好。如果原纸的含量>90wt%,湿法造高吸水树脂吸水纸的吸收性能差,干爽性差;如果原纸的含量<60wt%,湿法造高吸水树脂吸水纸柔软性差,不舒适,同时成本较高。
在本发明中,湿法造高吸水树脂吸水纸的克重为20~300g/m2,发明人发现当湿法造高吸水树脂吸水纸的克重低于20g/m2时,高吸水树脂的添加量较少,则湿法造高吸水树脂吸水纸的吸液效果不佳;当湿法造高吸水树脂吸水纸的克重高于300g/m2时,为了保证纸张质量和吸水效果,高吸水树脂的添加量较多,则会使得湿法造高吸水树脂吸水纸的整体重量较大,降低卫生吸收用品的轻便性。因此,在保证湿法造高吸水树脂吸水纸的高吸水性的基础上,湿法造高吸水树脂吸水纸更加轻薄,本发明湿法造高吸水树脂吸水纸的克重优选为上述范围。
根据一些优选的实施方式,所述透气底层14为PE透气底膜。
在第二方面本发明提供了一种上述第一方面所述的抑菌防漏型吸收物品的制造方法,所述制造方法包括如下步骤:
(1)在超导结构13的中部复合吸收结构12得到超导吸收结构;
(2)在所述吸收结构上层复合透液性表层11,在所述超导结构13的下层复合透气底层14,得到所述抑菌防漏型吸收物品。

实施例4与实施例1基本相同,不同之处在于:超导结构的翻折的角度为90°,不设置通孔。
实施例5:
实施例5与实施例1基本相同,不同之处在于:超导结构的翻折的角度为135°,翻折部分不设置通孔。
对比例1:

测试方法一:取动物血液2次,每次5mL,2次间隔10分钟,记录每次吸收完成的时间为吸收速度,单位s;反渗是每次加液5mL动物血液5min后,将1.2kg砝码压10g滤纸置于吸收物品上面1min,称量滤纸增加的克重,单位g;扩散是第二次反渗前1分钟进行横向方向的长度测量,单位cm。
测试方法二:随机找20人,保证其它卫生条件的前提下,分别对实施例1-5和对比例1-8的吸收物品进行佩戴试用,在经期每四个小时更换一次,判定干爽性效果。
测试方法三:随机找20人,分别对实施例1-5和对比例1-8的吸收物品进行佩戴试用,判定抑菌祛味效果。

特别需要说明的是,本发明中术语“上”、“下”等指示的方位或位置关系为基于附图1所示的方位或位置关系,仅是为了便于描述本发明和简化描述。
最后应说明的是:以上实施例仅用以说明本发明的技术方案,而非对其限制;尽管参照前述实施例对本发明进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
