摘要：
The present invention protects a disposable absorbent article friendly to the environment, in which at least half of the materials used to manufacture it, are compounds containing natural and / or biodegradable elements. The article of the present invention uses, as the top sheet of the article, a nonwoven fabric containing cotton or a nonwoven fabric containing polylactic acid (PLA) or poly-hydroxy-alcanoates (PHA), or a nonwoven fabric containing a pro-degrading agent. As back sheet of the article it uses a waterproof film containing polylactic acid (PLA) or poly-hydroxy-alcanoates (PHA), or a polyethylene film containing a pro-degrading agent, or a polyethylene film containing PLA, PHA or a pro-degrading, laminated with a non woven fabric containing cotton, or containing PLA or PHA, or containing a pro-degrading agent. As superabsorbent material, it uses a mixture containing at least 20% of natural and / or biodegradable particles. As fastening system it uses polymers containing PLA or PHA, polymers containing a pro-degrading agent. As barrier cuffs, it uses transfer layers or wrap layers, films containing PHA PLA or a pro-degrading agent. It uses adhesives containing PHA or PLA and elastic or elastomeric materials containing PLA, PHA or a pro-degrading agent.
