Description

一种防堆叠防返渗的纸尿裤
【技术领域】
本发明涉及纸尿裤的技术领域,特别涉及一种防堆叠防返渗的纸尿裤。
【背景技术】
众所周知,婴儿的皮肤是最为娇嫩的,而且对外界的防御能力低,过敏和出疹问题时常发生,目前市场上的纸尿裤品牌数十种之多,产品宣传五花八门,功能也越来越多,家长希望挑选一款好的纸尿裤,在保护宝宝皮肤同时,给予最舒适周全的体贴。纸尿裤选择不当或使用不当,尿布疹就会出现,而尿布疹是因尿液和大便的混合物及布尿布(或质量不好的纸尿裤)对皮肤的刺激和摩擦而引起的炎症,从阴部至臀部都出现微红现象,皮肤会变得粗糙,甚至出现极细小的粉刺,小屁股如果长痱子,同时又使用不透气的布尿布或质量不好的纸尿裤,也会引起尿布疹。
传统尿布透气性固然好,但是需要频繁更换,清洗量很大,稍不注意,宝宝的皮肤就容易浸泡在尿渍和便渍中,清洗和晾晒条件不好,容易滋生细菌,所以,挑选好的纸尿裤十分重要,而现市场上的纸尿裤具有防漏功能,但大多数锁水功能较低,且尿液多的时候,容易发生堆聚的现象,使宝宝的屁屁局部被尿渍浸泡,一旦外力的作用,局部堆聚的尿布中的尿液就会返渗,影响宝宝的舒适度。
芯体是纸尿裤关键,对芯体的改进是改善纸尿裤的核心所在,因此,为提高纸尿裤的锁水功能,防止尿液多致使出现堆聚现象,且较长时间不更换纸尿裤也不会影响宝宝的舒适度,有必要提出一种防堆叠防返渗的纸尿裤。
【发明内容】
本发明的目的在于克服上述现有技术的不足,提供一种防堆叠防返渗的纸尿裤,其旨在解决现有技术中尿液多时纸尿裤易出现堆聚现象,稍加外力就会出现尿液返渗,影响宝宝舒适度的技术问题。
为实现上述目的,本发明提出了一种防堆叠防返渗的纸尿裤,包括表面包覆层、底层防漏膜、弹性腰围、吸收芯层、防侧漏护围,所述表面包覆层与底层防漏膜粘连,所述表面包覆层与底层防漏膜之间填有吸收芯层,所述吸收芯层位于表面包覆层与底层防漏膜的中间位置,所述吸收芯层的所在位置两侧连有防侧漏护围,所述表面包覆层与底层防漏膜的纵向两端设有弹性腰围,所述后侧的弹性腰围两侧粘连有左右魔术贴,所述后侧的弹性腰围底面上占有前腰贴,所述吸收芯层由导流层、第一吸水锁水层、亲水无纺布层和第二吸水锁水层四部分构成,所述导流层位于表面包覆层的下方,所述导流层的下方依次连有第一吸水锁水层和第二吸水锁水层,所述第一吸水锁水层与第二吸水锁水层之间还设有亲水无纺布层,所述第一吸水锁水层和第二吸水锁水层由高分子吸水树脂和木浆混合而成,所述吸收芯层所在位置的表面包覆层上轧有规则排列的导尿孔。
作为优选,所述表面包覆层为亲水无纺布。
作为优选,所述导流层是由热风导流材料非织造而得,所述的热风导流材料所用的纤维原料为吸液能力强、持水能力较低的纤维长丝,所述纤维长丝方向与表面包覆层的纵向一致。
作为优选,所述纤维原料通过持久亲水处理,其纤维接触角为0~10°。
作为优选,所述热风导流材料通过开松处理,其蓬松度为20~25cm3/g。
作为优选,所述第一吸水锁水层由80%高分子吸水树脂和20%木浆均匀混合而成。
作为优选,所述第二吸水锁水层由20%高分子吸水树脂和80%木浆均匀混合而成。
作为优选,所述亲水无纺布层采用亲水纤维连续长丝通过纺粘工艺制得,其纤维接触角为0~5°。
作为优选,所述亲水纤维可为天然纤维、粘胶纤维中的一种或多种组合。
作为优选,所述导尿孔的最大外径为1~2mm。
本发明的有益效果:与现有技术相比,本发明提供的一种防堆叠防返渗的纸尿裤,结构合理,对现有的纸尿裤吸收芯层的结构进行改进,通过由不同比例的高分子吸水树脂和木浆混合而成的两层吸水锁水层对婴儿尿液进行吸水锁水,并且由持久亲水处理和开松处理得到的导流层对尿液进行疏导,较小的接触角和较高的蓬松度使其具有较快的吸液速度,此外,导尿孔的设置,加快了尿液被吸收的速度,防止尿液长时间接触婴儿肌肤,且导流层所用的吸液能力强、持水能力较低的纤维长丝,其排列方向与表面包覆层的纵向一致,能引导液体容易沿着导流层纵向(即纸尿裤的纵向)扩散,防止尿液被纸尿裤局部吸收,而导致堆聚现象,采用两层吸水锁水层,比例不同且互补,改善了现有纸尿裤由于长时间不换而吸液能力差的现状,提高了宝宝使用纸尿裤过程中的舒适度。
本发明的特征及优点将通过实施例结合附图进行详细说明。
【附图说明】
图1是本发明一种防堆叠防返渗的纸尿裤的结构示意图;
图2是本发明一种防堆叠防返渗的纸尿裤的吸收芯层断面示意图。
图中:1-表面包覆层、10-导尿孔、2-底层防漏膜、3-弹性腰围、4-吸收芯层、41-导流层、42-第一吸水锁水层、43-亲水无纺布层、44-第二吸水锁水层、5-防侧漏护围、6-左右魔术贴、7-前腰贴。
【具体实施方式】
为使本发明的目的、技术方案和优点更加清楚明了,下面通过附图中及实施例,对本发明进行进一步详细说明。但是应该理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限制本发明的范围。此外,在以下说明中,省略了对公知结构和技术的描述,以避免不必要地混淆本发明的概念。
参阅图1和图2,本发明实施例提供一种防堆叠防返渗的纸尿裤,包括表面包覆层1、底层防漏膜2、弹性腰围3、吸收芯层4、防侧漏护围5,所述表面包覆层1与底层防漏膜2粘连,所述表面包覆层1与底层防漏膜2之间填有吸收芯层4,所述吸收芯层4位于表面包覆层1与底层防漏膜2的中间位置,所述吸收芯层4的所在位置两侧连有防侧漏护围5,所述表面包覆层1与底层防漏膜2的纵向两端设有弹性腰围3,所述后侧的弹性腰围3两侧粘连有左右魔术贴6,所述后侧的弹性腰围3底面上占有前腰贴7,所述吸收芯层4由导流层41、第一吸水锁水层42、亲水无纺布层43和第二吸水锁水层44四部分构成,所述导流层41位于表面包覆层1的下方,所述导流层41的下方依次连有第一吸水锁水层42和第二吸水锁水层44,所述第一吸水锁水层42与第二吸水锁水层44之间还设有亲水无纺布层43,所述第一吸水锁水层42和第二吸水锁水层44由高分子吸水树脂和木浆混合而成,所述吸收芯层4所在位置的表面包覆层1上轧有规则排列的导尿孔10。
其中,导尿孔10有规则排列在吸收芯层4所在位置的表面包覆层1上,导尿孔10的最大外径为1~2mm,增加了尿液被纸尿裤吸收的速度,防止婴儿肌肤长时间与尿液接触。
进一步地,表面包覆层1为亲水无纺布,导流层41是由热风导流材料非织造而得,所述的热风导流材料所用的纤维原料为吸液能力强、持水能力较低的纤维长丝,所述纤维长丝方向与表面包覆层1的纵向一致。纤维长丝吸液能力强、持水能力较低使导流层41具有较强的输液能力,通过导流层41被第一吸水锁水层42和第二吸水锁水层44吸收,防止尿液返溢,且纤维长丝方向与表面包覆层1的纵向一致,使尿液能够沿着纸尿裤的纵向扩散和吸收,防止出现局部吸水而出现局部堆聚现象,影响了宝宝的舒适程度。
其中,纤维原料通过持久亲水处理,其纤维接触角为0~10°,热风导流材料通过开松处理,其蓬松度为20~25cm3/g。、在本发明实施例中,纤维接触角为5°,蓬松度为22cm3/g。
进一步地,第一吸水锁水层3由80%高分子吸水树脂和20%木浆均匀混合而成。高分子吸水树指具有高吸水量和高吸水保有量的特征,它的吸水量和保水量是木浆的几十倍,而木浆堆积在一起具有良好的毛细管,产生较高的导流分散作用,它的吸水速率大约是高分子吸水树脂的5~6倍,所以两者的性能具有互补性,合适的配比和混合构成的尿裤芯片能达到最佳吸收速率和吸水保有量的效果,而过高或者过低比例的高分子吸水树脂,均不能达到最佳吸收速率和吸水保有量的效果,通过不断试验得到80%高分子吸水树脂和20%木浆吸收速率和吸水保有量效果较好。
更进一步地,第二吸水锁水层5由20%高分子吸水树脂和80%木浆均匀混合而成。第二吸水锁水层5与第一吸水锁水层3的高分子吸水树脂和木浆比例不同且互补,当第一吸水锁水层3的高分子吸水树脂为吸水饱和时,通过第二吸水锁水层5的吸水还能吸入大量的尿液,改善了目前只有一层吸水锁水层而导致过饱和且纸尿裤长时间不更换后尿液返溢,对婴儿肌肤造成影响,出现红屁屁的现象,同时大大提高了纸尿裤的吸水锁水功能,提高了舒适度。
更进一步低,亲水无纺布层43采用亲水纤维连续长丝通过纺粘工艺制得,其纤维接触角为0~5°,亲水纤维可为天然纤维、粘胶纤维中的一种或多种组合。亲水纤维的接触角为0~5°较低,较容易将第一吸水锁水层3中不被吸收的尿液输送至第二吸水锁水层5,防止第一吸水锁水层3出现表面互相粘联和产生糊状的情况。
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、等同替换或改进等,均应包含在本发明的保护范围之内。
