Abstract

本发明涉及一种吸液透气抗血无渗漏卫生巾，由亲肤干爽层、透气储液芯体层、SMS抗血拒水无纺布层及底层叠加构成；亲肤干爽层位于透气储液芯体层吸收面，SMS抗血拒水无纺布层位于透气储液芯体层的背面，底层位于SMS抗血拒水无纺布层透气面。优点：一是SMS抗血拒水无纺布设计在透气储液芯体层背面，既达到了阻水的目的，又有效地阻止了经血的渗漏，实现了阻水、阻血、透气三者共存的目的的前提下，大大地减少了卫生巾产品的厚度；二是高分子复合SMS无纺布层的设计，既使吸液量大卫生巾的厚度得到了大大降低，又提高了大吸收量卫生巾对经血的吸收量，使女性在经期使用后从裤的臀部看不出卫生巾使用的痕迹。

Description

吸液透气抗血无渗漏卫生巾
技术领域
本发明涉及一种不仅能够快速吸收经液，而且在确保具有良好透气状态的前提下能有效地阻止经血渗出，同时又能在大大提高卫生巾使用舒适度的前提下，大大降低卫生巾厚度的吸液透气抗血无渗漏卫生巾，属于卫生巾制造领域。
背景技术
本申请人所有CN102961218B、名称“吸液透气无渗漏卫生巾”，卫生巾由亲肤干爽层与三层透气储液芯体层叠加构成或卫生巾由亲肤干爽层与二层透气储液芯体层叠加构成，每层透气储液芯体层由导流透气支层、储液透气支层和拒液透气支层叠加构成；所述三层透气储液芯体层底层两端间隔喷有胶条层，胶条层与离型纸粘贴；所述亲肤干爽层可以是水刺无纺布或打孔无纺布或打孔膜且水刺无纺布或打孔无纺布或打孔膜的背面喷有一层高分子树脂。
发明内容
设计目的：在背景技术的基础上，设计一种不仅卫生巾能够快速吸收经液，而且在确保卫生巾具有良好透气状态的前提下能有效地阻止经血渗出，同时又能在大大提高卫生巾使用舒适度的前提下，大大降低卫生巾厚度的吸液透气抗血无渗漏卫生巾。
设计方案：为了实现上述设计目的。1、SMS抗血拒水无纺布层位于透气储液芯体层2的背面的设计，是本发明的技术特征之一。这样做的目的在于：由于经血血浆总渗透压313mOsm，相当于7个大气压（5330毫米汞柱，1毫米汞柱=0.133千帕），其余为晶体渗透压；而SMS无纺布抗静水压mmH20>80>
110>130>150>200>220>250>280>300>300>300>300，远远小于经血血浆总渗透压，因此对于没有处理过的SMS拒水无纺布而言，只能够阻止水分子的通过，但无法有效阻止经液血浆的通过，而经过有机氟处理后的SMS无纺布的抗静水压mmH20远远大于5330毫米汞柱，它不但能够有效地阻止经血血成份的通过，而且具有良好的透气性，不会阻塞SMS无纺布，几乎不会增加SMS无纺布重量，不会改为SMS无纺布的手感，因此经过有机氟处理后的SMS无纺布既阻止了经血血浆的通过，又确保了SMS无纺布的阻水透气性能，本申请将SMS抗血拒水无纺布设计在透气储液芯体层背面，既达到了阻水、阻经血渗漏的目的，又实现了阻水、阻血、透气共存的目的。2、SMS抗血拒水无纺布层由一层SMS抗血拒水无纺布或多层SMS抗血拒水无纺布叠加构成的设计，是本发明的技术特征之二。这样设计的目的在于：虽然SMS抗血拒水无纺布在常态下能够阻止经血血浆的通过，但是由于女性每月月经的出血时间持续2～7天，每次失血量约为50～200毫升，当女性排出经液流量达到20ml时，才会有很少的经血达到SMS抗血拒水无纺布且被SMS抗血拒水无纺布阻止；只有当女性排出经液流量达到20ml以上时，才会有很少的经血在人体阴部混合气压压力的作用下微量渗出多层SMS抗血拒水无纺布层中第一层SMS抗血拒水无纺布且被第二层SMS抗血拒水无纺布所阻挡。3、高分子复合SMS无纺布层的设计，是本发明的技术特征之三。这样设计的目的在于：由于女性每月月经的出血时间持续2～7天，每次失血量约为50～200毫升，但无法确定每次失血量倒底有多少，使得女性有使用卫生巾时，在选择吸收量大、小卫生巾上往往处于犹欲不定的艰难选择中，如果选吸收量大的卫生巾时，由于卫生巾本身厚，使用后从裤的臀部能明显看出卫生巾的痕迹，使女性、特别职业女性往往感到很尴尬、不爽，犹其是在春、夏、秋节；如果选吸收量小的卫生巾，虽然厚度薄，使用后从裤的臀部看不出卫生巾的痕迹，但是当不确定的经液流量如果达到20ml以上时，微量渗出的经血往往会污染裤子，犹其是浅色裤子，其污染经液的显现给女性造成无法回避的尴尬。本申请在两层SMS抗血拒水复合无纺布之间喷有一层高分子树脂，由于该层高分子树脂的厚度小于2mm，既没有大幅增加卫生巾的厚度，使女性使用后从裤的臀部看不出卫生巾使用的痕迹，又使卫生巾的经血吸收量提高了50%左右，解决女性，特别是职业女性生理、职场的特定需求。
技术方案：一种吸液透气抗血无渗漏卫生巾，由亲肤干爽层、透气储液芯体层、SMS抗血拒水无纺布层及底层叠加构成；亲肤干爽层位于透气储液芯体层吸收面，SMS抗血拒水无纺布层位于透气储液芯体层的背面，底层位于SMS抗血拒水无纺布层透气面。
本发明与背景技术相比，一是SMS抗血拒水无纺布设计在透气储液芯体层背面，既达到了阻水的目的，又有效地阻止了经血的渗漏，实现了阻水、阻血、透气三者共存的目的的前提下，大大地减少了卫生巾产品的厚度；二是高分子复合SMS无纺布层的设计，既使大吸收量卫生巾的厚度得到大大降低，又确保了和提高了大吸收量卫生巾对经血的吸收量，从而使使女性在经期使用后从裤的臀部看不出卫生巾使用的痕迹，解决女性，特别是职业女性生理、职场的特定需求。
附图说明
图1是吸液透气抗血无渗漏卫生巾的结构示意图。
图2是复合SMS无纺布层的结构示意图。
图3是透气储液芯体层的第一种结构示意图。
图4是透气储液芯体层的第二种结构示意图。
具体实施方式
实施例1：参照附图1-3。一种吸液透气抗血无渗漏卫生巾，由亲肤干爽层1、透气储液芯体层2、SMS抗血拒水无纺布层3及底层4叠加构成；亲肤干爽层1位于透气储液芯体层2吸收面，即亲肤干爽层1叠加在透气储液芯体层2的吸液面上；SMS抗血拒水无纺布层3位于透气储液芯体层2的背面，即SMS抗血拒水无纺布层3叠加在透气储液芯体层2的背面。底层4位于SMS抗血拒水无纺布层3透气面，即底层4叠加在SMS抗血拒水无纺布层3透气面上。所述SMS抗血拒水无纺布层3由一层SMS抗血拒水无纺布或多层SMS抗血拒水无纺布叠加构成。所述底层4底面间隔喷有背胶条5。所述所述底层4两侧喷有翼胶条6。所述亲肤干爽层1可以是水刺无纺布或打孔无纺布或打孔膜。其吸液透气抗血无渗漏卫生巾制作方法系现有技术，在此不作详细的文字描述。
所述透气储液芯体层2由高分子树脂层201和无尘纸202叠加构成，高分子树脂层201位于无尘纸202上。所述透气储液芯体层2的面层为亲肤干爽层1、背层为SMS抗血拒水无纺布层3，即透气储液芯体层2中无尘纸202背面为SMS抗血拒水无纺布层3。
所述SMS抗血拒水无纺布克重为14-200克/平方米。
实施例2：参照图4。在实施例1的基础上，所述透气储液芯体层2由无纺布层203、高分子树脂层201和无尘纸202叠加构成；高分子树脂层201位于无尘纸202上，无纺布层203位于高分子树脂层201上。
实施例3：由于丙烯酸纤维有高吸水性能，该类纤维能够吸收超过自身重量25倍的液体，用丙烯酸纤维制作的无纺布因而具有高吸水性，因此本申请在实施例1或2的基础上，所述透气储液芯体层2采用纤维状吸液高分子无纺布替代，可以有效地减小卫生巾的厚度。
需要理解到的是：上述实施例虽然对本发明的设计思路作了比较详细的文字描述，但是这些文字描述，只是对本发明设计思路的简单文字描述，而不是对本发明设计思路的限制，任何不超出本发明设计思路的组合、增加或修改，均落入本发明的保护范围内。
