Abstract: A nonwoven fabric formed from filaments made from a polymer derived from L- and D-lactic acid. The nonwoven fabric is biodegradable and especially suitable for use in disposable hygiene products.

Abstract: The invention relates to a nonwoven based on thermoplastic filaments, wherein all the filaments of which it is composed are completely manufactured from a polymer or from a blend of polymers derived from lactic acid, said nonwoven being permanently hydrophilic.The filaments of which the nonwoven according to the invention is composed are continuous filaments.They may furthermore be subjected to a hydrophilic treatment using a surface-active agent.

Abstract: A totally biodegradable and/or compostable soft cloth-like composite of totally biodegradable and/or compostable film and totally biodegradable and/or compostable nonwoven and method of manufacture. A totally biodegradable and/or compostable nonwoven fibrous web and a totally biodegradable and/or compostable film are laminated. The laminate is incrementally stretched to produce a totally biodegradable and/or compostable laminate that is softer than that produced when the biodegradable and/or compostable nonwoven web is bonded to the biodegradable and/or compostable film. The soft cloth-like features of the invention are desired in a number of applications including diapers, pants, surgical gowns, sheets, dressings, hygienic products, and the like.

Abstract: The present invention relates to a composite structure comprising one or more plies of nonwoven and one or more plies of film, these being manufactured from thermoplastics, wherein all the plies making up the structure, for example (12, 13, 14), are totally manufactured from a member of the group: a polymer derived from lactic acid, a copolymer of lactic acid, a blend of polymers derived from lactic acid.The invention also relates to a process for obtaining said composite structure.
