Abstract: The present invention provides a liquid-absorbing material and a preparation method thereof, an absorbent core and an absorbent product, and belongs to the technical field of liquid-absorbing materials. The present invention can at least partially address the problem of poor absorption performance of existing absorbent cores. The liquid-absorbing material of the present invention comprises: polymer fiber, comprising a polymer fiber comprising a polymer material capable of melting when heated, wherein the polymer fiber has been partially molted; and an absorbent particle having liquid absorbing capacity, wherein when the polymer fiber is in the partially molten state, the absorbent particle is in contact with the polymer fiber, thereby bonding to the polymer fiber after the polymer fiber is cured.

Abstract: Some embodiments of the present disclosure relate to improving or overcoming at least one problem in existing air filters by including at least one folding structure in or on the air filter. The folding structure is capable of being bent to enable the air filter to be wrapped around or secured to a, for example, washing net. The folding structure can also hold the air filter securely to the, for example, washing net.
