Method for manufacturing decorated molding

Номер: US20120006480A1
Автор: Satoshi Ohya, Toshiro Ariga, Yoshinari Santo
Принадлежит: DIC Corp

There is provided a method for manufacturing a decorated molding having projections and depressions in a decorated surface, the method including, while a heat-shrinkable resin sheet is supported, a step (1) of creating a difference in thickness between an area A and an area B adjacent to each other in the same plane of the resin sheet through irradiation with infrared rays so that the area A and the area B have surface temperatures different from each other and the surface temperature of at least the area A is a surface temperature that is higher than or equal to a temperature T of an inflection point of orientation returning strength of the resin sheet and a step (2) of attaching the resin sheet to an adherend by vacuum forming to achieve integration. In a method for simultaneously performing vacuum forming and decoration, a decorated molding having projections and depressions in a decorated surface can be obtained with high reproducibility without requiring a physical method such as embossing.

Supported hollow fiber membrane

Номер: US20120156485A1
Автор: Attila Palinkas, Marcell MARSCHALL, Robert Szabo
Принадлежит: General Electric Co

A hollow fiber membrane is made by covering a tubular supporting structure with a membrane dope and converting the membrane dope into a solid porous membrane wall. Optionally, a textile reinforcing structure in the form of a circular knit may be added around the supporting structure before it is covered in dope. The reinforcing structure thereby becomes embedded in the membrane wall. The supporting structure may be soluble in a non-solvent of the membrane wall, for example water, and may be removed from the membrane. Alternatively, the supporting structure may be porous. A porous supporting structure may be made by a non-woven textile process, a sintering process within an extrusion machine, or by extruding a polymer mixed with a second component. The second component may be a soluble solid or liquid, a super-critical gas, or a second polymer that does not react with the first polymer.

The invention relates to methods for lowering the melt viscosity and thereby improving heat-sealability of a polyester. The invention also relates to a method for manufacturing a heat-sealed container or package from fibrous- based, polyester-coated packaging material, and a method for heat-sealing polyester. The solution according to the invention is subjecting polyester to electron beam (EB) radiation. The lowered melt viscosity allows a lower heat-sealing temperature, and permits sealing of polyester to an uncoated fibrous surface. The preferred polyester for the invention is polylactide, as such or as blended with another polyester.
