  • Patent number: 10259918
    Abstract: A method for producing a non-breathable micro-porous thermoplastic polymer film for outer covering of diapers and sanitary towels includes a dispersion step by mixture of mineral particles surface-covered with a hydrophobic layer of fatty acid, a base polymer and a co-polymer adhesive, wherein the co-polymer adhesive is selected to comprise the base polymer; and film forming step in a film extrusion line having a flat film extruder provided with an extrusion nozzle, wherein the mixture is fed to the flat film extruder forming the film, and hot stretching the film between the extrusion nozzle and the solidification of the formed film, thereby obtaining the non-breathable micro-porous film with pores sizing from 0.5 to 5 ?m without communication between the pores. The process requires less raw materials with a further reduction of film thickness, while giving a matt appearance to the film, thus making the usual micro-embossing step of the extrusion line unnecessary.

    Abstract: The present invention consists in a method and a composition for obtaining films of a thermoplastic polymer, preferably polyethylene, that are non-breathable and heavily charged with treated mineral particles in order to leave hollow spaces in the structure thereof, resulting in a significant reduction in density. Owing to the fact that said films exhibit improved stability to the stresses they undergo during processing in diaper-production machines, and because, furthermore, they offer an important saving in terms of costs owing to the high mineral-filler content thereof and the low density thereof, they are especially suited to use as an outer covering for disposable diapers and sanitary towels.

  • Patent number: 8518311
    Abstract: A biodegradable, substantially continuous filament is provided. The filament contains a first component formed from at least one high melting polyester and a second component formed from at least one low melting polyester. The low melting point polyester is an aliphatic-aromatic copolyester formed by melt blending a polymer and an alcohol to initiate an alcoholysis reaction that results in a copolyester having one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the alcoholysis conditions (e.g., alcohol and copolymer concentrations, catalysts, temperature, etc.), a modified aliphatic-aromatic copolyester may be achieved that has a molecular weight lower than the starting aliphatic-aromatic polymer. Such lower molecular weight polymers also have the combination of a higher melt flow index and lower apparent viscosity, which is useful in the formation of substantially continuous filaments.

  • Patent number: 8506871
    Abstract: A porous monocomponent nonwoven web contains a bimodal mass fraction/fiber size mixture of intermingled continuous microfibers and larger size fibers of the same polymeric composition. There are at least five times as many microfibers as larger size fibers, and a histogram of the mass fraction of fibers vs. fiber size exhibits a larger size fiber mode greater than 10 ?m. The web may be made by flowing fiber-forming material through a die cavity having larger size orifices and at least five times as many smaller size orifices to form filaments, attenuating the filaments into fibers and collecting the attenuated fibers to form the nonwoven web. The web is especially well suited to the manufacture of self-supporting three dimensional articles such as molded cup-shaped respirators and pleated air filters.

    Abstract: Method for making plastic fiber for application in concrete with largest grain diameters >4 mm, with an average diameter of 0.15 to 2 mm, corresponding to approximately 160 to 28,000 dtex. Using a co-extrusion process, a bi-component fiber is formed having a central core and a casing around the central core, the central core and the casing contain different pure polymers or polymer mixtures, and then the co-extruded bi-component fiber is stretched by a factor of 5 to 15, and thereafter a structured or grooved surface is embossed onto the co-extruded stretched bi-component fiber. The embossing is performed such that a depth of the embossing is more than 10% of an average fiber diameter, and a maximal distances of structure tips within incorporated structures of the embossing in an axial direction lie in a region between 0.5 mm and 3 mm.
