Title: ABSORBENT ARTICLE
Abstract:
Provided are biodegradable absorbent articles that are able to retain similar physical properties to those of absorbent articles that use components made from conventional synthetic resin while also keeping the environment at landfill spaces for such used absorbent articles safe. The absorbent article includes a plurality of synthetic resin sheets, each of the plurality of synthetic resin sheets containing an oxidative decomposition agent and having a disintegration time (Dh) measured by a heat promotion test at 80°C of 36 hours or longer. Furthermore, the difference (∆Di) between the decomposition rate indices (Di) of each synthetic resin sheet of the plurality of synthetic resin sheets satisfies the relationship -36/k≤∆Di≤36/k.
