Description
技术领域
本发明涉及卫生裤技术领域,特别是一种三角型卫生裤及制造方法。
背景技术
现有技术中卫生裤是一种常用的卫生用品,包括成人纸尿裤以及女性经期裤,即是把卫生巾做成短裤的形状,跟穿纸尿裤的方式一样使用,不仅吸收量大,而且防侧漏,比较适合经量大、户外运动的女性以及产妇。目前受限于材质等工艺影响很难做到轻薄型,穿着后透气性能差使得穿着时闷热感强烈且外形美观性较差。
后专利申请号:2021108289556,公开了一种三角型吸收裤,使得吸收裤的侧面的整体厚度较小,更加轻薄透气,削弱了鼓胀感,但是其还是存在一部分缺陷,即吸收裤内部面层还是采用无纺布制作,而采用无纺布和纯棉材料相比还是存在舒适度降低的问题,但是传统的卫生裤受限于设备和工艺,还很难将棉质材料做为表层。
发明内容
针对现有技术存在的不足,本发明提供一种三角型卫生裤及制造方法。
为了达到上述目的,本发明通过以下技术方案来实现:一种三角型卫生裤,包括吸收部和对称设置于所述吸收部两侧的第一侧腰和第二侧腰,第一侧腰和第二侧腰的前、后边部分别与吸收部的前、后部连接,其特征在于:所述吸收部从外至内包括基膜层、防渗层、吸收层、导流层以及表面层,所述表面层由棉质表层和面层导引无纺布组成,所述棉质表层粘合在面层导引无纺布上,面层导引无纺布两侧拼接防侧漏拒水无纺布。
优选的:第一侧腰和第二侧腰的前、后边部分别与吸收部的前、后部连接,连接处采用超声波焊接,连接效果好。
优选的:所述第一侧腰和第二侧腰的材质选自高弹性无纺布或弹性非织造布,所述第一侧腰和第二侧腰内设置有多条弹性橡筋,所述的基膜层采用底层无纺布,基膜层的腿部区域设置有S橡筋。第一侧腰和第二侧腰内设置有多条弹性橡筋,便于调节腰部松紧度。
优选的:所述吸收层包括棉芯、高吸水树脂、上卫生纸和下卫生纸,上卫生纸和下卫生纸覆盖包裹有高吸水树脂的棉芯,能大量吸收水分溶胀又能保持住水分不外流。
优选的:所述吸收层、导流层和表面层两边通过左右对称的两片防侧漏拒水无纺布进行平面覆盖。
优选的:所述吸收层、导流层和表面层两边通过一体式的防侧漏拒水无纺布进行立体包裹,并在两侧边加入橡筋。相比平铺覆盖吸收体形式改为立体包裹,中部形成浮起立体,减少了防渗层两侧覆盖的拒水无纺布与皮肤的接触面,实际使用更有干爽透气感,芯体两侧边加入了橡筋,橡筋有一定的收缩形成向上的凹面,与人体裆部贴合度更高,横截面呈W形状,进一步防止侧漏的发生,提升了使用安全感。
一种三角型卫生裤的制造方法,其特征在于以下步骤:
S1、将棉芯和高吸水树脂混合在专用成型模轮内腔成型,下卫生纸表面预先喷胶,然后转移到下卫生纸固定棉芯导引出,在棉芯表面采用专用小螺旋胶枪进行施胶,这种施胶方式保证材料之间的粘合又具有疏散的透气孔道,再覆盖上卫生纸组成吸收层;
S2、棉质表层通过施加设备配合将棉质表层粘合在面层导引无纺布上,防侧漏拒水无纺布与面层导引无纺布两侧通过三片压纹花棍热压和配合三片胶复合,组合成面层,与私密处接触位置表面层均为棉的材质;
S3、基膜层的腿部区域布置一定轮廓的S橡筋,腿部S橡筋通过专用机构按照特定的动作路线运动与预先在预定区域刮胶的防渗层两侧覆盖拒水无纺布定位粘合定形,防止渗漏和侧漏;
S4、依次将基膜层、防渗层、吸收层、导流层以及表面层进行依次层叠结合,且吸收层、导流层和表面层通过两边防侧漏拒水无纺布进行平面覆盖或两边一体式的防侧漏拒水无纺布进行立体包裹;
S5、第一侧腰和第二侧腰的前、后边部分别与吸收部的前、后部连接,连接处采用超声波焊接;
S6、焊接一体后通过成型切刀切出腿部弧线,折叠包装成品。
优选的:S2步骤中施加装置包括机座依次安装在机座上的接料器料架、主动牵引辊、二级张力控制器、材料纠偏控制器、小螺旋喷胶枪、负压输送风斗和分切刀箱总成,分切刀箱总成包括机架、分切刀箱、旋转分切刀、负压分切底辊、负压装置和压合轮,负压装置与负压分切底辊和负压输送风斗连接。
优选的:S2步骤中棉质表层通过施加设备配合将棉质表层粘合在面层导引无纺布上,具体为,首先成卷的棉质表层安装在外置进料料架放卷料轴上,材料依次经过自动换接料装置---→材料缓冲储料装置一次张力控制进行收卷和放卷的均匀控制---→牵引导出---→机器主墙板接料器料架,然后依次经过主动牵引辊和二级张力控制器,通过二级张力控制器对输送过程中的棉质表层进行张力控制---→材料纠偏控制器---→通过小螺旋喷胶枪在棉质表层材料内表面均匀施加特定的复合胶---→喷胶后的棉质表层材料经输送风斗---→约束棉质表层材料进入分切刀箱---→吸附到负压分切底辊表面---→通过旋转分切刀旋转切割将棉质表层材料分切成预定需要的长度---→切割后定长的棉质表层材料随着负压分切底辊转动---→转移到主线材料定点位覆盖到产品的面层导引无纺布上,最后通过压合轮压合完成。
本发明具有有益效果为:
本发明在卫生裤表面层设置有棉质表层,使得舒适度变高,更亲肤。
采用的制造工艺能有效平衡处理了现有传统的设备和工艺很难将棉材料作为表面层与裤腰无纺布超声波焊接结合在一起的矛盾,有效提高了卫生裤实际使用的舒适度。
本发明卫生裤不易发生侧漏,吸收层吸收量大,提升了使用安全感,第一侧腰和第二侧腰选用的材料轻薄且弹性较好,第一侧腰和第二侧腰内设置有多条弹性橡筋,便于调节腰部松紧度。

S6、焊接一体后通过成型切刀切出腿部弧线,折叠包装成品。
参考附图6,S2步骤中施加装置包括机座依次安装在机座上的接料器料架、主动牵引辊、二级张力控制器、材料纠偏控制器、小螺旋喷胶枪、负压输送风斗和分切刀箱总成,分切刀箱总成包括机架、分切刀箱、旋转分切刀、负压分切底辊、负压装置和压合轮,负压装置对负压分切底辊和负压输送风斗进行供给。
S2步骤中棉质表层12通过施加设备配合将棉质表层12粘合在面层导引无纺布15上,具体为,首先成卷的棉质表层12安装在外置进料料架放卷料轴上,材料依次经过自动换接料装置---→材料缓冲储料一次张力控制进行收卷和放卷的均匀控制---→牵引导出---→机器主墙板接料器料架,然后依次经过主动牵引辊和二级张力控制器,通过二级张力控制器对输送过程中的棉质表层12进行张力控制---→材料纠偏控制器---→通过小螺旋喷胶枪在棉质表层12材料内表面均匀施加特定的复合胶---→喷胶后的棉质表层12材料经输送风斗---→约束棉质表层12材料进入分切刀箱---→吸附到负压分切底辊表面---→通过旋转分切刀旋转切割将棉质表层12材料分切成预定需要的长度---→切割后定长的棉质表层12随着负压分切底辊转动---→转移到主线材料定点位覆盖到产品的面层导引无纺布15上,主线材料可以通过负压箱进行吸附,防止脱离主线,最后通过压合轮压合完成。
本发明在卫生裤表面层设置有棉质表层12,使得舒适度变高,更亲肤。采用的制造工艺能有效平衡处理了现有传统的设备和工艺很难将棉材料作为表面层与裤腰无纺布超声波焊接结合在一起的矛盾,有效提高了卫生裤实际使用的舒适度。
本发明卫生裤不易发生侧漏,吸收层吸收量大,提升了使用安全感,第一侧腰2和第二侧腰3选用的材料轻薄且弹性较好,第一侧腰2和第二侧腰3内设置有多条弹性橡筋,便于调节腰部松紧度。
实施例2
如图7所示,实施例2与实施例1基本相同,不同的是所述吸收层、导流层7和表面层两边通过一体式的防侧漏无纺布8进行立体包裹,并在两侧边加入橡筋11。相比平铺覆盖吸收体形式改为立体包裹,中部形成浮起立体,减少了防渗层5两侧覆盖的无纺布与皮肤的接触面,实际使用更有干爽透气感,芯体两侧边加入了橡筋,橡筋有一定的收缩形成向上的凹面,与人体裆部贴合度更高,横截面呈W形状,进一步防止侧漏的发生,提升了使用安全感。
上述实施例仅用于解释说明本发明的发明构思,而非对本发明权利保护的限定,凡利用此构思对本发明进行非实质性的改动,均应落入本发明的保护范围。
