  • the structure of paper towels can be divided into single-layer, double-layer, and multi-layer; multi-layer paper towels are easy to be peeled off during the extraction process.
  • embossing In order to change the layering of the paper, the various layers of paper are adhered by embossing. It also affects the physical properties of paper towels such as thickness, touch (surface softness), absorbency (fluffy softness), and embossing technology has become a key link in papermaking technology that affects the performance of paper towels.

Description

一种纸巾及制造方法
本申请要求于2019年08月16日提交中国专利局、申请号为201910760175.5、发明名称为“一种纸巾及制造方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种纸巾及其制造方法，具体说是一种多层制品的制造方法。
背景技术
纸巾，一般通过木浆、竹浆、棉浆、草浆等天然无污染的原料制造而成，按照用途来分包括纸面巾、纸餐巾、纸手帕、湿巾、擦手纸、厨房纸巾等，根据纸巾的结构可分为单层、双层、多层；多层纸巾在抽取过程中容易分层剥离的可能，为了改变纸的分层，通过压花将各层纸粘连，压花过程中其对纸巾的厚度、触感(表面柔软性)、吸收性(蓬松柔软性)等物理性能也带来了影响，压花工艺成了造纸技术中影响纸巾性能的关键环节。
当前市面存在的压纹卫生纸结构主要由压纹工序和压纹后卫生纸的粘合制作而成(压花复合结构)。而现有压纹卫生纸主要以二路径压纹为主，而现有已知公开的三路径压纹卫生纸巾受到工艺制约使得现有三路径压纹结构产品相对二路径压纹产品优势并无明显。
CN201510439764.5生产多层压花卫生卷纸的方法，原纸拆卷：将待压花的原纸拆卷；面层细压花：将一层或一层以上的面层原纸引至上细压花辊对压制细压花得细压花纸；面层与芯层粗压花：得到的细压花纸与一层芯层原纸合卷引至粗压花辊对进行粗压花得粗压花纸，涂结合剂：得到的粗压花纸引至涂结合剂水橡胶辊与粗压花钢棍构成的辊对，对得到的粗压花纸芯层侧凹面涂结合剂得点胶粗压花纸；底层细压花：将一层底层原纸引至下细压花辊对压制细压花得底层细压花纸；复卷、包装：将得到的点胶粗压花纸与得到的底层细压花纸复卷，点胶粗压花纸的粗压花凹面与底层细压花纸凹面在复卷过程中粘合连接，包装，得到面层凸面与底层凸面均相对设置的多层压花卫生卷纸。
上述方案虽然实现了面层、芯层、底层的三路径压花，由于受到工艺制约使得现有三路径压纹结构产品相对二路径压纹产品优势并无明显。面层，因为受到两次的压花，卫生纸中纤维结合点被较大程度的拉伸断裂破坏，导致面层卫生纸强度低，湿水后易烂，造成用户体验下降。而两次压花的面层和芯层结合后并形成的结构并不能对产品厚度结构有太大提升，吸收性和手感变化不明显。
