【附图说明】
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其它的附图,其中:
图1为本发明提供的纸尿裤的立体结构示意图;
图2为图1所示的裆围部的分层结构示意图;
图3为图2所示的无纺布隔层的横截面结构示意图。
【具体实施方式】
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明的一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
请参阅图1,本发明提供了一种纸尿裤100,其包括纸尿裤本体1及与所述纸尿裤本体1连接的松紧带2。
所述纸尿裤本体1包括位于中间位置的裆围部11、与所述裆围部11一端连接的腰围部12及与所述裆围部11另一端连接的腹围部13,所述腰围部12包覆婴儿的腰部,所述腹围部13包覆婴儿的腹部,所述裆围部11、所述腰围部12及所述腹围部13一体成型。
请参阅图2及图3,所述裆围部11用于与婴儿的裆部相兜围,并盛接婴儿排除的尿液。所述裆围部11包括依次层叠设置的透水层111、吸收芯体112及防漏底层113。
所述透水层111由无纺布制成,直接与婴儿皮肤接触,接收尿液并传递至下一层。在本实施方式中,所述透水层111为具有单向导水功能的全棉无纺布,其包括靠近婴儿皮肤的疏水层1111及与所述疏水层1111相对设置的亲水层1112,尿液在重力和毛细作用力的作用下,由所述疏水层1111朝向所述亲水层1112方向移动,并渗入所述吸收芯体112,所述疏水层1112可以对尿液形成隔绝,避免尿液的回流,可以保证在所述疏水层1111不会有尿液残留,保持干爽,避免尿液的淤积对婴儿的皮肤造成不利的影响。
所述吸收芯体112设置于所述纸尿裤100的中间区域,其作用主要是吸收并锁住尿液,保证所述纸尿裤100的透水层111的干爽性。
所述吸收芯体112包括热风无纺布垫层1121、热风无纺布隔层1122、吸水颗粒1123及绒毛浆层1124。其中,所述热风无纺布垫层1121与所述防漏底层113连接,所述绒毛浆层1124与所述透水层111连接。
所述热风无纺布垫层1121的形状为椭圆形,所述热风无纺布隔层1122及所述绒毛浆层1124的形状与所述热风无纺布垫层1121的形状相匹配,即,所述吸收芯体112整体也呈椭圆形。可以理解的是,由于婴儿排尿位置的局域性,使得所述吸收芯体112的中间区域为主要尿液接收区域,而边缘区域为尿液扩散区域,所述吸收芯体112采用椭圆形的设计,正好可以满足接收及扩散尿液的需求,同时减小了所述吸收芯体112整体所需要的面积,减少了成本。
所述热风无纺布隔层1122与所述热风无纺布垫层1121热风粘合连接。具体的,所述热风无纺布隔层1122包括多个相互交叉设置的第一分隔条10和第二分割条20,相邻两个所述第一分隔条10配合相邻两个所述第二分隔条20形成两端开口的收容空间30。可以理解的是,所述热风无纺布隔层1122的横截面呈网格状,所述第一分隔条10和所述第二分隔条20的设置方向与所述热风无纺布垫层1121垂直,所述热风无纺布垫层1121对所述收容空间30的一端开口形成封堵。
所述吸水颗粒1123收容于所述空间30内,所述吸水颗粒1123由高分子树脂颗粒和龙脑樟粉末混合而成,其中,所述高分子树脂颗粒与所述龙脑樟粉末的质量为比(40-50):1,优选的,所述高分子树脂颗粒与所述龙脑樟粉末的质量为比40:1。
所述高分子树脂颗粒能吸收自身重量500-1000倍的水,吸水效果较佳。同时,所述绒毛浆层1125的纤维及表面结构构成导流的毛细管结构,可以在相邻两个所述高分子树脂层1124间形成传输通道,可以进一步实现尿液的良好扩散,进而所述吸收芯体112内层中心区域的尿液也能够向四周扩散。
并且相关技术中,所述高分子树脂层1124吸收尿液后膨胀变软,颗粒之间的间隙在较小的压力之下就会被堵塞起来,使得所述吸收芯体112的透气性能较差,所述龙脑樟粉末与所述高分子树脂颗粒均匀混合后,使得所述高分子树脂颗粒间夹设有所述龙脑樟粉末,可以有效限制所述高分子树脂颗粒的过度膨胀,保持颗粒间间隙的通常,进而保持良好的透气性能。
进一步,所述龙脑樟粉末有通诸窍、散郁火、去翳明目,消肿止痛,开窍醒神,消热解毒,消炎止痛,化腐生肌,祛风化痰,抗癌治癌等功效,可以有效避免长时间穿着造成的皮肤过敏,同时,还对病患使用者具有良好的治疗保健效果,并且所述龙脑樟颗粒散发出的香味可以抑制尿液的异味。需要说明的是,所述龙脑樟粉末由龙脑樟叶片提取而得,成本较低。
更进一步的,所述吸水颗粒1123收容于所述收容空间30内,所述第一分隔条10和所述第二分隔条20对所述吸水颗粒1123形成限位,避免所述吸水颗粒1123的移动造成所述吸水颗粒1123分布不均,影响所述吸收芯体112的吸水性能。同时,相邻两个所述收容空间30间由所述第一分隔条10和所述第二分隔条20形成间隔,所述第一分隔条10和所述第二分隔条20内部的纤维间隙形成了良好的透气通道,进一步加强了所述吸收芯体112的透气性能。
所述绒毛浆层1124除了有吸收能力以外,还是很好的液体传导媒介,其纤维及表面结构构成导流的毛细管结构,非常有利于液体的水平方向及垂直方向扩散,起到很好的导流作用,使得所述透水层111传导过来的尿液进入所述吸收芯体112的表层时就能够快速均匀的扩散,进一步减少尿液的淤积,并使尿液扩散分布,增加了所述吸收芯体112的利用率,从而使尿液很快离开婴幼儿的肌肤,保持皮肤干爽;在吸收量一定的情况下,还可以适当缩减所述吸收芯体112的体积,节约资源,减少生产及使用成本。
所述防漏底层113的作用主要是保证吸收芯体112吸收的尿液不会从所述纸尿裤100的底部渗漏出去,从而不会弄脏婴儿的其它衣物。同时还必须得保证好的透气性,所述防漏底层113可采用透气性薄膜或透气薄膜与非织造布的复合体等为原料。
所所述松紧带2配合所述腰围部12和所述腹围部13对所述纸尿裤100穿着时进行固定,避免所述纸尿裤100脱落,具体的,所述松紧带2包括与所述腹围部13连接的本体部21及自所述本体部21两端向外延伸的两个弹性部22,所述弹性部22远离所述本体部21的一端设有魔术贴221,所述腹围部13上设有与所述魔术贴221相匹配的粘贴部131,所述魔术贴221可对应粘贴于所述粘贴部131,所述弹性部22的长度可调节,以满足不同体型婴儿的需求。
本发明还提供一种上述吸收芯体的制作方法:
提供热风无纺布垫层,将所述热风无纺布垫层铺平;
提供热风无纺布隔层,所述热风无纺布隔层包括多个相互交叉设置的第一分隔条和第二分隔条,相邻两个所述第一分隔条配合相邻两个所述第二分隔条形成两端开口的收容空间,将所述热风无纺布隔层与所述热风无纺布垫层热风粘合连接,使所述热风无纺布垫层对所述收容空间的一端开口形成封堵;
提供吸水颗粒,所述吸水颗粒由高分子树脂颗粒和龙脑樟粉末混合形成,将所述吸水颗粒填充至所述收容空间;
提供绒毛浆层,将所述绒毛浆层与所述热风无纺布隔层胶合,使所述绒毛浆层对所述收容空间的另一端开口形成封堵。
其中,所述吸水颗粒中,所述高分子树脂颗粒与所述龙脑樟粉末的质量比为(40-50):1,优选的,所述吸水颗粒中,所述高分子树脂颗粒与所述龙脑樟粉末的质量比为40:1,所述龙脑樟粉末由龙脑樟叶片提取而得。
与相关技术相比,本发明的提供的纸尿裤100中包括吸收芯体112,所述吸收芯体112中的吸水颗粒1123由高分子树脂颗粒和龙脑樟粉末混合而成,具备良好的吸水性能及透气性能,同时,所述吸收芯体112的热风无纺布隔层1122包括多个收容空间30,所述吸水颗粒1123收容于所述收容空间内,可以对所述吸水颗粒1123进行限位,避免所述吸水颗粒1123的移动。
以上所述的仅是本发明的实施方式,在此应当指出,对于本领域的普通技术人员来说,在不脱离本发明创造构思的前提下,还可以做出改进,但这些均属于本发明的保护范围。
