Systems and methods can be used to produce fibers with external corrugations, internal corrugations, or both. These fibers can be used, for example, in hollow fiber membrane modules.

Provided are: a method and apparatus for manufacturing a highly permeable elastic sheet; a method and apparatus for manufacturing a highly gas-permeable stretchable composite sheet; and a highly gas-permeable stretchable composite sheet. An elastic resin material containing a thermoplastic elastic resin as a main component is melted by being heated to a temperature higher than a temperature range in which the elastic resin material is elastically deformed, the molten elastic resin material is discharged in a fibrous or linear form, the discharged elastic resin material (intermediate) is applied in a net shape onto a cooling member, the applied elastic resin material is cooled by the cooling member to the temperature region in which the elastic resin material is elastically deformed, and the applied elastic resin material is solidified to obtain an elastic sheet. The elastic sheet and non-woven fabrics are stacked and joined to obtain a stretchable composite sheet.

Disclosed herein are high melt flow polypropylene homopolymers generally characterized by a melt flow rate ranging from 200 g/10 min to 3000 g/10 min, a ratio of Mw/Mn ranging from 2 to 5, and a peak melting point ranging from 138 C. to 151 C. These polypropylene homopolymers can be produced by catalyst systems containing a racemic ansa-bis(indenyl)zirconocene compound, an activator-support, and an organoaluminum co-catalyst.

Sucker ring tooth (SRT) proteins called Suckerins were identified from the sucker tissue of three distantly related Decapodiformes species. These proteins assemble into silk-like beta-sheet reinforced materials. The use of suckerin proteins to produce fibres, films and tissue scaffolds is also described.

This invention involves a new and better solution to the problems associated with the premature softening of PLA filaments in the additive manufacturing of three dimensional articles. It is based upon the finding that poly(lactic acid) filaments with high crystallinity offer much better resistance to heat-induced softening. The crystalline poly(lactic acid) filament of this invention can accordingly be used in the additive manufacturing of three dimensional articles without encountering the problems associated with premature softening, such as poor quality and printer jamming The crystalline poly(lactic acid) filaments of this invention can also be used in additive manufacturing of three dimensional articles without compromising the quality of the ultimate product, reducing printing speed, increasing cost, or leading to increased printer complexity. This invention more specifically discloses a filament for use in three-dimensional printing which is comprised of crystalized poly(lactic acid), wherein said filament has a diameter which is within the range of 1.65 mm to 1.85 mm

A polymer body includes a first thermoplastic polymer, and a second thermoplastic polymer. The first thermoplastic polymer and the second thermoplastic polymer form a continuous solid structure. The first thermoplastic polymer forms an external supporting structure that at least partially envelops the second thermoplastic polymer. A first flow temperature of the first thermoplastic polymer is at least 10 C. higher than a second flow temperature of the second thermoplastic polymer. The first thermoplastic polymer may be removable by exposure to a selective solvent.
