  • Composite elastic nonwoven fabric
    Patent number: 11161321
    Abstract: Elastic nonwoven composites suitable for a wide variety of uses are provided. The composite includes at least one extensible nonwoven layer, including a first extensible nonwoven layer, and at least one elastic nonwoven layer, in which the nonwoven layer comprises elastic continuous filaments. The composite may be bonded and activated by, at least in part, a stretching operation. The elastic continuous filaments may comprise an additive, such as a slip additive.
    Type: Grant

  • Process for making a nonwoven web derived from lactic acid, web produced thereby, and apparatus therefor
    Patent number: 5833787
    Abstract: The invention relates to a process for the manufacture of a nonwoven web using filaments of melted polymers, of the type including the steps of spinning the polymer or polymers, of cooling, drawing and laying down fibers on a belt and of bonding said fibers by calendering in order to form said nonwoven web (15), which process furthermore includes a treatment (13, 14) of setting/adjusting the degree of crystallinity of and the internal tension in the fibers making up the nonwoven web. The invention also relates to the nonwovens obtained by the process and to the installations for implementing it.

  • Laminated nonwoven webs derived from polymers of lactic acid and process for producing
    Patent number: 5702826
    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.
