Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 and fig. 2, a dry and comfortable three-dimensional 3D raised hot air non-woven fabric of water conservancy diversion, including from top to bottom in proper order compound outer hot air non-woven fabric 1, absorb sandwich layer 2 and inlayer hot air non-woven fabric 3, outer hot air non-woven fabric 1 surface equidistant upwards protrusion is formed with a plurality of vertical extension, the bellying 9 of transverse distribution, the depressed part 10 between the adjacent bellying 9 is connected with absorption sandwich layer 2, a plurality of through-holes 4 have been seted up on the depressed part 10 surface, bellying 9 surface is provided with a plurality of horizontal extension, the guiding gutter 5 of longitudinal distribution.
