Dimensionally stable, breathable, stretch-thinned, elastic films

A method for producing a stretch-thinned elastic article having dimensional stability over time and at elevated temperatures in which a thermoplastic block copolymer is melt-processed into a stretchable article such as a film or fiber. The article is then conditioned at an elevated temperature greater than or equal to a glass transition temperature (Tg) of a hard phase of the thermoplastic block copolymer. The article is stretch-thinned at the elevated temperature to a desired percentage stretch, forming a stretch-thinned article, after which it is cooled to a temperature below the glass transition temperature of the hard phase of the thermoplastic block copolymer. Films produced by this method are suitable for use in durable and disposable articles including personal care articles such as diapers, incontinence wear, training pants, and feminine care articles, as well as wound dressings, wipes, towels, napkins, and protective apparel.

Method and device for manufacturing three-dimensional bodies

A method for producing three-dimensional bodies of a large number of mutually connected layers of a particle-shaped material such as a powder, and where the information of the appearance of each layer is achieved from a computer's CAD-unit or similar. An essentially even particle layer (7) of building material is applied on a support base (6) and on a masking device (9) is arranged a masking pattern in accordance with the information from the CAD-unit, which masking device is led over said particle layer and close to it. A radiation producer (8) is arranged or is led over the masking device (9), whereby the particles which are not covered by the masking pattern are exposed for radiation and thereby are attached to each other. The masking pattern is removed from the masking device and new sequences in accordance with the above are carried through until the three-dimensional body (19) is produced.

Blend material including macrocyclic polyester oligomers and processes for polymerizing the same

A blend of a macrocyclic polyester oligomer and a polymerization catalyst as a one component ready-to-use material with a long shelf life enables production of parts from macrocyclic polyester oligomers without the modification of existing equipment, thereby reducing time and cost of manufacture while expanding the application of macrocyclic polyester oligomers. In this blend material, the macrocyclic polyester oligomer remains intact in solid state at ambient conditions. Upon melting, the blend material initially forms low viscosity fluid, and then rapidly polymerizes to form high molecular weight polyesters which subsequently solidify to form crystalline polymers. In the case of certain macrocyclic polyester oligomers, for example, poly(1,4-butylene terephthalate), demolding can take place at the polymerization temperature, e.g., at about 180° C. to 200° C., because the resulting polyester polymer solidifies fairly rapidly at that temperature without cooling. In one aspect, the invention generally features a blend material that includes a macrocyclic polyester oligomer, a polymerization catalyst, and optionally, a filler. In another aspect, the invention generally features a process for preparing a blend material. In yet another aspect, the invention features processes such as rotational molding, resin film infusion, pultrusion, resin transfer molding, filament winding, making and using powder-coated or hot melt prepreg, compression molding, and roll wrapping, which use the blend material.
