摘要： Disclosed are methods and devices for forming a combined polyester and fiberglass mat, in which separate polyester and fiberglass layers can be formed or polyester filaments and fiberglass threads can be mixed together by a disperser to form a polyester and fiberglass web. The polyester filaments and the fiberglass threads can be dispersed by separate dispersers on a web forming belt to form separate layers of polyester filaments and fiberglass threads, or can be dispersed by a single disperser to at least, somewhat evenly disperse, the fiberglass threads and polyester filaments.

摘要： The present invention discloses a method for preparing a fiber with spatial structure, and the fiber prepared thereby and its use as well. In this method, the fiber is prepared through a wet spinning process, wherein a spinning solution prepared from low molecular weight polysaccharide based polyelectrolyte optionally with inert conductive material distributed therein, is injected through a syringe into a coagulation bath, which is formed by adding high molecular weight polysaccharide based polyelectrolyte into a coagulation tank. This method has the advantages such as simple equipment, low cost, good spinnability, and is applicable for large-scale production. The prepared fiber with spatial structure, especially the hollow multilayered fiber, has the controllable layers, cavities, and diameter, a high tensile strength, and an ultra-high specific surface area.

摘要： 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.

摘要： The disclosed methods and apparatus improve the fabrication of solid fibers and microstructures. In many embodiments, the fabrication is from gaseous, solid, semi-solid, liquid, critical, and supercritical mixtures using one or more low molar mass precursor(s), in combination with one or more high molar mass precursor(s). The methods and systems generally employ the thermal diffusion/Soret effect to concentrate the low molar mass precursor at a reaction zone, where the presence of the high molar mass precursor contributes to this concentration, and may also contribute to the reaction and insulate the reaction zone, thereby achieving higher fiber growth rates and/or reduced energy/heat expenditures together with reduced homogeneous nucleation. In some embodiments, the invention also relates to the permanent or semi-permanent recording and/or reading of information on or within fabricated fibers and microstructures. In some embodiments, the invention also relates to the fabrication of certain functionally-shaped fibers and microstructures. In some embodiments, the invention may also utilize laser beam profiling to enhance fiber and microstructure fabrication.

摘要： The present invention relates to gels and processes for making bundles of aligned ceramic nanofibers, ceramic nanostructures made by such processes, and methods of using such ceramic nanostructures. Such process is templated via block copolymer self-assembly but does not require any post processing thermal and/or solvent annealing steps. As a result, such process is significantly more efficient and scalable than other processes that are templated via block copolymer self-assembly. The resulting fibers are aligned according to the direction of deposition, making steps where individual fibers are bundled unnecessary.
