Description

一种成人纸尿裤
技术领域
本发明涉及一种日用品，特别是一种成人纸尿裤。
背景技术
目前是市场上的成人纸尿裤的主要包括非透水性外层、吸收体、透水性内层、左右贴、防漏侧翼和腿部弯曲弹性带等结构，其中左右贴都釆用PP材料制成，使用时重复粘合次数少、粘合力不够，尤其是透气性差知识使用舒适度低，而且防漏性能差。
发明内容
本发明的发明目的在于：针对上述存在的问题，提供一种良好透气性，方便穿脱，吸水性强，防侧漏的成人纸尿裤。
本发明采用的技术方案如下：
本发明的一种成人纸尿裤，包括裤体及裤体上的防漏侧翼、前腰贴和后腰贴，所述前腰贴固定在裤体的外侧面上，后腰贴分为左后腰贴和右后腰贴，所述左后腰贴和右后腰贴分别固定在裤体后部的左右两侧上；所述防漏侧翼设置在裤体长度方向的中部的左右两侧；所述裤体具有层状结构，该层状结构从上至下依次为吸附层，吸收层，第一膨胀层，第二膨胀层和防漏层。
由于采用了上述技术方案，左后腰贴和右后腰贴可以方便穿脱。吸附层能够吸附的身体上，不易移位，不易侧漏；吸收层，第一膨胀层，第二膨胀层提高吸收性能，有效防止侧漏。
本发明的一种成人纸尿裤，所述吸附层由改性纳米聚乙烯醇静电丝编织而成，编织孔径为300nm，厚度为0.2mm，所述改性纳米聚乙烯醇静电丝的直径为520nm；所述吸附层表面设有若干透气孔，所述透气孔的孔径大小为3cm。
由于采用了上述技术方案，改性纳米聚乙烯醇静电丝与人体具有良好的静电吸附作用，经过测试对人体安全无刺激无过敏；编织而成材料自身具有良好的透气吸水性；吸附层表面设有透气孔，能够进一步提高吸附层的透气吸水性。
本发明的一种成人纸尿裤，所述改性纳米聚乙烯醇静电丝通过以下步骤制备而成，
步骤一：称取1份纤维素，取适量去离子水搅拌溶解，按纤维素：四甲基哌啶氧化物摩尔比1:0.05向溶液中加入四甲基哌啶氧化物，按照纤维素：次氯酸钠摩尔比1:1向溶液中加入次氯酸钠，调节体系pH为10.3，在室温下搅拌24h；
步骤二：通过均质机分散体系至凝胶状，经过超声处理10min，过滤后冷冻干燥，制得纳米纤维素；
步骤三：称取1份聚乙烯醇，取适量去离子水，加热至80℃并保持恒温，搅拌2h至完全溶解；
步骤四：自然冷却至常温，稀释聚乙烯醇溶液为浓度23%，按聚乙烯醇：水性聚氨酯质量比1:0.43搅拌30min，按照聚乙烯醇：纳米纤维素质量比1:0.6，搅拌30min；
步骤五：通过微量注射泵进行静电纺丝，静电纺丝的针头内径为0.4mm，针头距离接收器的距离为30cm，电源使用20kV静电高压，流量为0.5mL/h。
由于采用了上述技术方案，制备出的改性纳米聚乙烯醇静电丝具有良好的静电吸附作用，且柔韧性高。
本发明的一种成人纸尿裤，所述吸收层由亲水材料制成，其厚度为1.8cm。
由于采用了上述技术方案，吸收层具有良好的吸水性，能够有效防止侧漏。
本发明的一种成人纸尿裤，所述亲水材料包括18%木棉纤维，13%涤纶丝，12%棉纶丝，57%聚酰胺酯纤维丝。
由于采用了上述技术方案，吸收层的吸水性能优异，且对皮肤无刺激。
本发明的一种成人纸尿裤，所述第一膨胀层的厚度为4cm，所述第二膨胀层的厚度为2.5cm；所述第一膨胀层与第二膨胀层的长度比为1:0.6，所述第一膨胀层与第二膨胀层的宽度比为1:0.7；所述第一膨胀层与第二膨胀层由柔性吸水纤维制成，所述柔性吸水纤维包括43%粘胶人造丝纤维，30%聚丙烯和27%黄原胶接枝丙烯酸-丙烯酰胺共聚物。
由于采用了上述技术方案，采用两层膨胀层，提高了尿不湿的承载量，有效防止侧漏。第二膨胀层的尺寸较第一膨胀层小，由于中间部位吸收量最大，在最大限度提高承载量的同时减小不必要的材料，节约成本，上述比例为最佳值。添加黄原胶接枝丙烯酸-丙烯酰胺共聚物的吸水性能优异，能够有效避免渗漏。
本发明的一种成人纸尿裤，其特征在于：所述柔性吸水纤维通过以下步骤制备而成，
步骤一：称取1份黄原胶，加入适量的去离子水，搅拌溶解后按体积比黄原胶溶液：丙烯酸溶液=1:2.5向黄原胶溶液中加入中和度为85%的丙烯酸溶液，搅拌均有后向混合溶液中按体积比丙烯酸溶液：丙烯酰胺溶液=1:1，向混合溶液中加入丙烯酰胺溶液；
步骤二：加热混合溶液至70℃，按照体积比混合溶液：交联剂=1:0.05，加入交联剂N,N-亚甲基双丙烯酰胺，保持70℃恒温搅拌1h；
步骤三：加热至85℃，按照体积比交联剂：引发剂=1:1向溶液中加入引发剂过硫酸钾溶液，继续恒温85℃搅拌2h后结束反应；
步骤四：将产物用体积比水：甲醇=1:4的洗涤剂洗涤若干次，放入60℃真空干燥箱中干燥12h，制得黄原胶接枝丙烯酸-丙烯酰胺共聚物。
由于采用了上述技术方案，该共聚物表面结构致密，但表面有大小不一的孔隙，有利于水分子迅速进入复合材料的内部而提高材料的吸水倍率。
本发明的一种成人纸尿裤，所述防漏层由疏水材料制成，其厚度为0.4cm。
由于采用了上述技术方案，防漏层能够有效阻隔水从防漏层漏出，减少渗漏的可能性。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1、与人体具有良好的静电吸附作用，对人体安全无刺激无过敏，能够吸附的身体上，不易移位，不易侧漏。
2、具有良好的透气吸水性能，提高使用时的舒适度，且对皮肤无刺激，在最大限度提高承载量的同时减小不必要的材料，节约成本。
3、在有效防止侧漏的同时进一步阻止渗漏，提高了使用时的舒适卫生程度。
