[0075] refer to Figure 1 to Figure 3 , an embodiment of the present invention provides a method for preparing any one of the above-mentioned liquid-absorbent materials, which includes:
[0076] The polymer fibers 1 are brought into contact with the absorbent particles 2, and the polymer fibers 1 are partially melted by heating, so that the absorbent particles 2 are attached to the polymer fibers 1 after the polymer fibers 1 are cooled and solidified.
[0077] That is to say, under the condition that the polymer fiber 1 is partially melted, it can be brought into contact with the absorbent particles 2, so that after cooling and solidification, the absorbent particles 2 can be connected (fused) to the polymer fiber 1 to form the above-mentioned Liquid absorbent material.
[0078] In the above preparation method, it is enough to ensure that the polymer fiber 1 is in contact with the absorbent particle 2 w...

Abstract
The invention provides a liquid absorption material, a preparation method of the liquid absorption material, an absorption core and an absorption product, and belongs to the technical field of liquidabsorption materials. According to the liquid absorption material, the preparation method of the liquid absorption material, the absorption core and the absorption product, the problem can be at leastpartially solved that an existing absorption core is poor in absorption performance. The liquid absorption material comprises polymer fibers which comprise polymer materials molten by heat energy andare partially molten previously, and absorption particles with a liquid absorption capacity, the absorption particles make contact with the polymer fibers in a partially-molten state, and therefore after the polymer fibers are cured, the absorption particles are connected to the polymer fibers.
Description
technical field [0001] The invention belongs to the technical field of liquid absorbing materials, and in particular relates to a liquid absorbing material and a preparation method thereof, an absorbing core and absorbing products. Background technique [0002] In products such as disposable diapers and sanitary napkins, the absorbent core is the core structure. Traditional absorbent cores include pulp fibers such as wood and cotton, but these fibers have poor absorbent properties. For this reason, absorbent particles of super absorbent polymers (SAP, Super absorbent polymers) can also be added to the pulp fibers of the absorbent core, but the amount added is limited, otherwise problems such as gel blockage and separation of absorbent particles will be caused. [0003] Therefore, the absorbent performance of the existing absorbent cores is poor. Contents of the invention [0004] The present invention at least partially addresses the problem of poor absorbent performance...
