Description

一种可拆卸式地毯 技术领域
本发明涉及纺织行业的地毯，具体涉及一种可拆卸式地毯。
背景技术
标准浴垫和地毯有两种设计方法：第一种是设计成类似毛巾的浴垫，这样可以洗涤。但是这种地垫不防滑，具有安全隐患；另一种方法是将具有防滑功能的材料粘结到地毯背面，这种地毯宣称可水洗，但是一旦在机器中洗涤就会分离或破损，或者上层面料和下层底背分离。而且，传统地毯设计和制造繁琐、价格较贵的特性阻碍这种地毯的多适用性。例如，它不允许使用者季节性的、根据需要随意换掉地毯。因此，需要一种地毯，既要具有常规地毯的功能，又要方便使用者将地毯的面层材料与具有防滑、拒水性能的衬垫层分离开来，对地毯的面层材料进行拆洗。
现有技术中，有使用魔术贴来连接地毯的毯面和衬垫的复合地毯。魔术贴是用子母两面将两层结构连接在一起的，魔术贴的一面是由细小柔软的纤维圈毛(Loop)组成，另一面是较硬带钩的刺毛(Hook)，两者的结合非常牢固，需要使用较大的力才能使其分开，由于要使两者分开的拉力会比较大；因此采用魔术贴连接地毯的毯面和衬垫，对于柔软的地毯而言，较大的作用力很可能会造成地毯的损坏，且拆卸不很方便。魔术贴中较硬的一面也会降低地毯的使用舒适度。并且，魔术贴或砂砾状垫层对柔软的圈绒布有很大的破坏作用，经过多次使用后连接力大大降低。
通过对现有专利文献的检索发现，申请号为201520843605.7的中国实用新型专利公开了一种可拆卸式的防滑地毯；其中，基体层的顶面上设有多个均匀分布且具有收缩性的插孔；连接层的底面上设有与插孔一一对应的插头；毛纺层编织固定在连接层的顶面上。然而，该地毯制作工艺繁杂，基体层的顶面与连接层的底面的连接无弹性，人走在上面有回声，隔音效果差；同时，连接时插头和插孔要完全对其才能插合，操作不方便，往往需要专业施工人员来进行操作；此外，拆卸以及清洗过程中插头容易损伤，并且受温度等因素影响发生变形，严重影响地毯的使用寿命。
申请号为201711361727.2的中国发明专利申请公开了一种可拆解的地毯；该地毯 的主体结构为基布层，基布层的顶部和底部的左右两侧均设有卡条，且两组防水层与基布层连接处均设有与卡条相配合的固定槽，通过卡条与固定槽相配合实现防水层和基布层的拆装，通过防水层的左侧和右侧均设有的卡块和卡槽相配合，可以对防水层和基布层进行巩固连接。然而，这种防水层和基布层的卡接连接方式属于外设的与地毯非一体的机械结构连接，卡槽有拼缝，同时地毯比较硬，适合大面积铺设，因此，通常适用于宾馆办公室而非家庭用。
发明内容
本发明的目的在于克服上述现有可拆洗复合地毯存在的使用时结合力过高导致拆卸时容易损坏毯面，结合力过低的影响使用效果，以及拆卸不方便、使用寿命欠佳等的缺陷，提供了一种可拆卸式地毯。
本发明的目的是通过以下技术方案来实现的：
本发明涉及一种可拆卸式地毯，包括毯面和防滑垫，
所述毯面包括面层和底层的三维网布结构层；
所述防滑垫包括底层的防滑拒水层和上层的结合层，所述结合层为布设若干涤纶、丙纶或尼龙单丝凸起的单面面料；
所述涤纶、丙纶或尼龙单丝凸起可插入所述三维网布结构层的网维间隙中。
作为本发明的一个实施方案，所述涤纶、丙纶或尼龙单丝凸起与单面面料的夹角为40°～90°。
作为本发明的一个实施方案，所述结合层是三维网布结构层中间剖开形成的单面结构层；所述三维网布结构层是由上下两层的经编网眼布和中间竖向排列的连接该上下两层经编网眼布的若干涤纶、丙纶或尼龙单丝组成。
上述单面结构层的单面经编网眼布上，单个网眼的面积为0.2平方毫米～100平方毫米
上述三维网布结构层是采用20D～120D的涤纶、丙纶或尼龙单丝一体化编织而成。更具体是采用20D～120D的涤纶单丝纱线一体化编织而成。当涤纶单丝低于20D时，在结合层上形成的涤纶单丝凸起太软，将导致无法插入毯面底层的三维网布结构层的网维间隙中或是只能少部分插入，进而达不到本发明的结合强度高等效果。
作为本发明的一个实施方案，所述结合层是用20D～120D的涤纶、丙纶或尼龙单丝织成的单面簇绒面料，或是用20D～120D的涤纶、丙纶或尼龙单丝织成的单面植绒面料。
本发明中，所述结合层上涤纶、丙纶或尼龙单丝凸起的高度为1.5mm～10mm。
作为本发明的一个实施方案，所述毯面的底层的三维网布结构层由上下两层的经编网眼布和中间竖向排列的连接该上下两层经编网眼布的若干涤纶、丙纶或尼龙单丝组成。所述涤纶、丙纶或尼龙单丝与上层或下层经编网眼布的夹角为40°～90°。
该三维网布结构层的厚度为2mm～20mm；上下两层的经编网眼布上单个网眼的面积为0.2平方毫米～100平方毫米。
作为本发明的一个实施方案，所述毯面的底层的三维网布结构层也是采用20D～120D的涤纶单丝纱线一体化编织而成。
作为本发明的一个实施方案，所述面层为毛绒层、平织层，圈绒中的至少一种或几种结构的组合形态。
作为本发明的一个实施方案，所述防滑拒水层为发泡乳胶层、热塑弹性体材料层、腈纶树脂层、EVA发泡层、聚氨酯发泡层、XPE发泡层或IXPE发泡层。
作为本发明的一个实施方案，所述毯面的三维网布结构层的四周或四个顶角设有可水洗、可移动的(用纳米技术制成的)聚氨酯和亚克力材料双面胶贴。该双面胶贴用于增强毯面四周与防滑垫的结合。
与现有技术相比，本发明具有如下有益效果：
1、本发明的防滑垫的结合面采用三维网布结构层中间剖开形成的单面结构层，该单面结构层上的涤纶单丝与经编网眼布是一体化的，不易脱落，提高了使用寿命；
2、本发明的防滑垫的结合面(尤其是采用三维网布结构层中间剖开形成的单面结构层)上的20D～120D的涤纶单丝可形成粗、硬，具有一定挺度的凸起，可以方便和随意的插合到毯面底层的三维网布结构层的网眼中，也可方便地进行拆卸，且可反复拆卸多次不损坏；
3、本发明的毯面底层采用三维网布结构层，与防滑垫的结合面是同一种材质；同时由于三维网布结构层具有一定的厚度，当结合面上的凸起插入网眼时，该凸起同时也插入三维网布结构层中间的连接涤纶单丝的间隙中；这两点都使得毯面与防滑垫复合使用时，结合强度高，不容易在使用坏境中发生移动，四周也不会起翘，具有良好的舒适性；
4、毯面与防滑垫均使用了整个/半个三维网布结构层，二者的插合使用赋予了本发明的地毯良好的弹性，提供使用者舒适性和保护的同时，也延长了地毯自身的使用寿命；
5、本发明的可拆卸式地毯可卷可折叠，运输方便。

性能验证
现有技术存在一种具有垫部的地毯；由罩和下方防滑不吸水的垫通过罩上的圈和垫上的钩互锁机械连接相互附着而构建。
该互锁机械连接在第一实施方案中由VELCRO形成，这种VELCRO具有魔术贴效果，然而拆卸多次圈和钩被破坏，如10次就出现绒面被破坏现象，导致粘结强度不够。
该互锁机械连接在第二实施方案中由所述垫上的粒状物材料层形成，罩采用起绒布，其上面的圈细微，肉眼很难看出，而垫上的粒状物材料层是由垫上3D-18D的短纤维经热处理形成砂砾层；因此，这种互锁连接强度欠佳；并且，使用过程中罩的四周会起翘， 影响使用者体验感。此外，由于垫上的粒状物材料层是由垫上纤维经热处理形成砂砾层，其无法卷曲、折叠。
该互锁机械连接在第三实施方案中由具有与所述罩的底表面互锁的突起的树脂材料形成。然而，这种罩和垫的互锁机械连接的结合力很差。
以上述第二实施方案为对照组1，以上述第一实施方案为对照组2；将对照组1、对照组2与实施例1的可拆卸式地毯进行如下实验：
