摘要:
It is an object of the invention to provide a layered absorbent sheet with excellent absorption properties including fluid retention, fluid diffusibility and absorbed fluid retention volume, and with particularly excellent deformation resistance against deformation by twisting and wrinkles.A layered absorbent sheet comprising a first sheet layer on the absorbing side, a second sheet layer on the non-absorbing side, and a super-absorbent polymer layer between the first sheet layer and second sheet layer, wherein the first sheet and/or second sheet are bulky absorbent sheets, the bulky absorbent sheets comprising heat-expanding particles that are dispersed in the bulky absorbent sheet and have been expanded by heat.
