Technical Problem

[0004]上述专利文献公开了一种吸收层顶面设有导流槽的纸尿裤,该纸尿裤的吸收层在两道上吸收体之间形成一条导流槽,并且导流槽沿长度方向延伸,纸尿裤在吸收尿液的过程中,面层的底面会紧贴吸收芯顶面,使得面层顶面相对导流槽的位置也会形成一条导流槽,尿液会沿着面层的导流槽扩散,导致尿液与吸收芯难以有效地直接接触,从而影响吸收层吸收尿液的效率并导致尿液可能会从纸尿裤的前腰围或后腰围处外漏,因此该纸尿裤仍有改进空间

Benefits of technology

本实用新型公开了一种内部具有可以引导液体高效扩散、渗透的导流结构的吸收制品,该吸收制品的吸收芯体顶面设有引导液体扩散的导流槽,而导流槽内的导流结构可以对面层进行支撑,保证液体沿面层与吸收芯体之间进行扩散,使液体进行大范围扩散的同时避免液体在前腰围或后腰围处向外渗漏,导流结构还可以通过内部较强的毛细效应促进液体向下渗透,使得液体沿导流槽扩散的同时可以快速地渗透至吸收芯体中,有利于提高吸收制品对液体吸收的效率。
