Description

 Urine pad with novel absorption layer and processing method thereof

 The invention relates to a urine pad, in particular to a urine pad having a novel absorbent layer and a processing method thereof. Background technique

 At present, commercially available diaper pads are usually made up of a mixture of fluff pulp and a polymeric water absorbing layer to form an absorbing layer, which is then laminated by a top layer and a bottom layer. After the user uses the urine pad, the water absorbing layer is swollen by a large amount of water, and the water absorbing layer is inflated to form a water absorbing mass. The water absorbing mass pulls the fluff pulp and the user twists during the movement, so that the water absorbing group Due to the uneven force and the different pressing and pulling forces, the absorbing pad of the diaper pad is entangled, agglomerated, broken, delaminated, broken or unevenly transported, which causes the user to In the case of the first time replacement, various discomforts may occur, and even the phenomenon that the polymer water absorbing layer expands and is squeezed and overflows, which seriously affects the user's health. Summary of the invention

 In order to overcome the above drawbacks of the prior art, embodiments of the present invention provide a urine pad having a novel absorbent layer and a processing method thereof, which divide the absorbent layer into a plurality of mesh structures and are fixed so that the fluff in the absorbent layer The slurry and polymer water absorbing layer are not easily deformed and broken.
