Description

一种带有刚性立体结构的男性轻度失禁巾 技术领域
本发明涉及一次性卫生用品领域，尤其涉及一种带有刚性立体结构的男性轻度失禁巾。
背景技术
尿失禁是不能由意识控制排尿功能、尿液不自主地经尿道流出的现象。仅少量尿液泄露被称为轻度失禁，虽然尿液泄露量少，但并不意味着受影响的人所经历的不适不严重。除了配合医生进行药物治疗外，在治疗期间有必要使用失禁用品，用于保护穿戴者免于尿液泄露。传统的轻度失禁用品一般都是男女通用，结构与卫生巾基本相同，没有考虑到男人与女人之间生理结构的差异，导致男性穿着者在使用过程中舒适体验感差，尿液吸收效果不佳。因此有必要研发设计专门用于轻度失禁男性的失禁用品，满足该群体的客观需求。
中国专利申请号：201020187013.1公开了一种男性尿失禁垫，具有垫体，所述垫体适宜于与内裤的裆部相连接；垫体有木浆和高分子混合构成的棉芯层，棉芯层的正面为无纺布层，背面为防水膜层，所述无纺布层与防水膜层的周边有压边；所述垫体的基本面为矩形，长边的其中一端有两边对称的斜切边；所述棉芯层与无纺布层与防水膜层之间有结构胶粘接层；所述垫体沿长边方向两侧各设有一橡筋，橡筋周边有三片式压纹；所述垫体的背面沿长边方向的两端各设有一离形纸。该实用新型设计符合男性的生理特点增加尿液的吸收，加快尿液的扩散、渗透，不会出现渗漏现象。
中国专利申请号：201922487369.0公开了一种男性轻度失禁尿片，包括表层、吸收体层、底膜、背胶层、离型纸与导流槽，尿片由里向外依次为表层、吸收体层、底膜、背胶层和离型纸，导流槽设置在表层与吸收体层之间，表层为最里层，与人体肌肤接触，所述背胶层与患者内裤贴合，离型纸设置在背胶层外，为尿片最外层，当患者失禁时，液体被导流槽迅速扩散，首先浸透表层，然后被吸收体层吸收，底层的PE膜能有效阻隔液体，使液体储存在吸收层内。该实用新型表层、吸收体层与底层均为低面密度，整体重量轻，并通过压轮压实吸收体层，使得吸收体层厚度最小为0.08cm，大大降低整体尿片厚度，佩戴隐蔽性好。
中国专利申请号：201922433247.3公开了一种成人轻度失禁品，包括绵柔表层、导流层、吸收体、底膜层和离型纸，所述导流层和吸收体构成内芯，所构成的内芯被夹设在所述绵柔表层和所述底膜层之间，在所述底膜层的底部黏贴有双面胶带，所述离型纸设置于所述底膜层的下方，且覆盖住所述双面胶带，所述绵柔表层的中部位置处为吸收区域，所述吸收区域的对应男性睾丸和阴部的位置处均布有渗透孔，在所述吸收区域的表面前后对称设置有侧向防漏凹槽，在所述侧向防漏凹槽内向下贯穿设置有渗透槽；该轻度失禁品专门针对成年男性设计，可以有效的承接漏尿。
但是男性患者穿戴上述这些男性失禁用品后，在不同场景下(比如四处走动或者坐下)，失禁用品不能保证总是呈现预期的形状，提供最佳的失禁保护以及穿着舒适性。
发明内容
因此，针对以上内容，本发明提供一种带有刚性立体结构的男性轻度失禁巾，解决现有失禁用品穿着舒适性不佳，无法很好地贴合内裤，时刻提供有效的失禁保护的问题。
为达到上述目的，本发明是通过以下技术方案实现的：
一种带有刚性立体结构的男性轻度失禁巾，包括失禁巾本体，定义沿失禁巾本体的长度方向为纵向，沿失禁巾本体的宽度方向为横向，所述失禁巾本体包括由上到下依次叠层设置的亲肤面层、导流层、吸收芯体和防漏底层，所述导流层和吸收芯体之间设有定型层，所述定型层包括上无纺布和下无纺布，所述上无纺布和下无纺布之间设有刚性强度的网状垫片，所述失禁巾本体的纵向方向设有第一折叠线，所述第一折叠线与纵向中轴线重合，所述亲肤面层上设有粘合区，所述粘合区上涂覆热熔胶，所述粘合区位于网状垫片的纵向一侧，当沿着第一折叠线对折时，粘合区粘合失禁巾本体形成立体凸台结构。
进一步的改进是：所述失禁巾本体的横向方向设有第二折叠线，所述第二折叠线位于失禁巾本体的中部，通过第一折叠线、第二折叠线的对折以及粘合区的粘合形成更贴合男性生理构造的立体结构。
进一步的改进是：所述第二折叠线与横向中轴线的间距为0-10cm。
进一步的改进是：所述防漏底层包括透气膜和设于透气膜底部的疏水无纺布。
进一步的改进是：所述吸收芯体包括吸收层和包覆在吸收层外的包覆层。
进一步的改进是：所述包覆层呈e形折叠结构。
进一步的改进是：所述吸收层为含有SAP的绒毛浆。
进一步的改进是：所述网状垫片的材质为金属、软塑料或软塑料包裹金属中的任意一种。网状垫片也可以选用其他具有一定刚性结构的材质，只要满足网状垫片的刚性强度要求即可：(1)折叠后不易折断；(2)受力后容易弯曲。
进一步的改进是：所述网状垫片中部网孔密集，两侧网孔稀疏，使网状垫片的中部刚性强度强于两侧的刚性强度。
进一步的改进是：所述上无纺布和下无纺布是复合纤维经水刺工艺制得，所述复合纤维包括芯层和包覆于芯层外表面的皮层组成，所述皮层为PTT纤维，所述芯层为改性海藻酸纤维，所述改性海藻酸纤维由湿法纺丝制得：将海藻酸钠、N-2-嘧啶基-4-氨基苯磺酰胺溶于氢氧化钠溶液中，真空脱泡12-20h，得到纺丝原液，经过纺丝、凝固、牵伸、清洗、干燥、卷绕后，即得改性海藻酸纤维。
进一步的改进是：所述海藻酸钠、N-2-嘧啶基-4-氨基苯磺酰胺的质量比为1:0.3-0.6，所述海藻酸钠在纺丝原液中的浓度为2-5％。
进一步的改进是：所述上无纺布和下无纺布经过抗菌后整理，使其表面负载有抗菌材料，所述抗菌后整理是利用抗菌整理剂实现的，所述抗菌整理剂包括以下重量份的各原料：润湿剂Morwet EFW 2-4份、羟丙基三甲基氯化铵壳聚糖4-8份、有机硅柔软剂1-3份、水性聚氨酯乳液12-20份、水35-55份。
进一步的改进是：所述网状垫片通过粘合剂与上下无纺布进行粘接，所述网状垫片的面积小于上无纺布和下无纺布，所述下无纺布与网状垫片未重叠部分粘有泡沫双面胶，所述泡沫双面胶粘接上无纺布和下无纺布的周边。
进一步的改进是：所述粘合剂包括以下重量份的各原料：丙烯酸缩水甘油酯15-30份、氢化松香醇8-15份、乙烯-1-辛烯共聚物12-18份、邻苯二甲酸二甲酯1-3份、填料10-30份、油酸酰胺1.5-4.5份。
通过采用前述技术方案，本发明的有益效果是：
1、本发明通过设置网状垫片、第一折叠线、粘合区的设置，当沿着第一折叠线对折时，粘合区粘合失禁巾本体形成刚性的立体凸台结构，符合男性的生理结构，穿着舒适，可以有效地吸收漏尿。进一步，设置第二折叠线，通过第一折叠线、第二折叠线的对折以及粘合区的粘合形成更适合男性生理构造的立体结构，与内裤形状完美贴合，时刻提供失禁保护。网状垫片具有一定刚性结构，可以更好地保持立体空间结构，不受男性消费者使用场景的影响。
将网状垫片设计成中部网孔密集，两侧网孔稀疏的结构，既可以满足失禁巾的要求，又不浪费材料，节约了成本。
2、将网状垫片夹设在上无纺布和下无纺布之间，可以起到对网状垫片位置的限定，避免网状垫片在使用过程中的移位，影响消费者的体验感。进一步，在下无纺布与网状垫片未重叠部分粘有泡沫双面胶，泡沫双面胶的设置可以更好地防止网状垫片出现移位的现象。
3、网状垫片通过粘合剂与上下无纺布进行粘接，传统的粘合剂(比如聚氨酯胶粘剂)可以实现金属、塑料、木材等相同材料之间的粘接，也可以实现不同材料之间的粘接，但研究发现当网状垫片的材质为金属时，与上下无纺布之间的粘接力小，无法满足实际要求，局限了网状垫片材质的选择。本发明提供一种可以在各种材质下均能保证粘接效果的粘合剂，试验结果表明：当本发明制备的粘合剂用于金属材质网状垫片与无纺布粘接时，剥离强度大于120N/25mm粘接效果好。
4、本发明的上无纺布和下无纺布由皮芯型复合纤维经水刺工艺制得，复合纤维兼具PTT纤维的手感柔软、富有弹性、干爽、优异的伸长恢复性和良好的挺括性，海藻酸纤维的高吸湿性、保健功效、生物降解性和相容性。利用N-2-嘧啶基-4-氨基苯磺酰胺与海藻酸钠共混纺丝，制得的改性海藻酸纤维具有良好的抗菌性，N-2-嘧啶基-4-氨基苯磺酰胺上的氨基与海藻酸钠分子中-OH、-COOH形成分子间作用力，二者之间相互交联，改善了海藻酸纤维的力学性能。
进一步，将上下无纺布进行抗菌后整理，使无纺布表面负载抗菌材料。该步骤与上述添加抗菌剂共混纺丝制备具有抗菌功能的复合纤维有效结合，实现了二次抗菌整理的效果，获得高抗菌性的上下无纺布。利用抗菌整理剂实现抗菌后整理，抗菌整理剂中羟丙基三甲基氯化铵壳聚糖具有良好的抗菌性、成膜性、抗静电性等性能，使得经抗菌整理后的上无纺布和下无纺布具有良好的抗菌性、抗静电性，但研究发现经过整理后的无纺布对液体的下渗速度变慢。润湿剂Morwet EFW不仅能够起到很好的分散作用，改善抗菌整理剂的表面张力，使其更好地润湿上下无纺布，提高整理液在无纺布表面的附着量，而且弥补了羟丙基三甲基氯化铵壳聚糖的缺点，加快了无纺布对液体的下渗速度。有机硅柔软剂的添加，大大增强了无纺布的柔韧性、透气性。水性聚氨酯乳液可以与纤维分子中的羟基、氨基发生反应，在无纺布上形成网络交联结构，起到增强无纺布力学性能的作用。
