| 摘要 |
A sanitary article comprises a biodegradable plastic material that has Bacillus spores incorporated therein. The biodegradable plastic material may be based on cellulose (e.g. lyocell, cellofane, viscose), starch or modified-starch, other naturally occurring polymers or monomers (e.g. polylactic acid), bacterially produced polyesters (e.g. PHAs) or chitosan. The biodegradable plastic material may be a breathable film containing a filler material; the filler may comprise the Bacillus spores. The filler material may be made by spraying calcium carbonate with a liquid containing Bacillus spores followed by a drying step. Such sanitary articles may prevent premature biodegradation since the embedded Bacillus spores are essentially kept inactive until after use. The sanitary article may be a wet wipe, dry wipe, panty liner, tampon, nappy, diaper or incontinence pad.
