Improved fibrillated fibers made by fibrillating an oriented film or sheet, where the film or sheet is from about 70 to about 99.5 weight percent of polypropylene and from about 30 to about 0.5 weight percent of a rubber selected from the group consisting of polybutadiene or polystyrene/polybutadiene block copolymer.

Photovoltaic materials and methods of photovoltaic cell fabrication provide a photovoltaic cell in the form of a fiber. These fibers may be formed into a flexible fabric or textile.

Long rod shaped M13 viruses were used to fabricate one dimensional (1D) micro- and nanosized diameter fibers by mimic the spinning process of the silk spider. Liquid crystalline virus suspensions were extruded through the micrometer diameter capillary tubes in cross-linking solution (glutaraldehyde). Resulting fibers were tens of micrometers in diameter depending on the inner diameter of the capillary tip. AFM image verified that molecular long axis of the virus fibers were parallel to the fiber...

The present invention provides an optical fiber enabling signal transmission in a wider band, which is applicable to optical transmission not only in the 1.3 .mu.m wavelength band but also in the 1.55 .mu.m wavelength band, as a transmission medium of a WDM optical communication system capable of transmitting signal light of multiple channels. The optical fiber is comprised of silica glass and has a core region along a predetermined axis and a cladding region provided on the outer periphery of t...

This invention pertains to novel fibers made of .alpha.(1.fwdarw.;3) polysaccharides, and a process for their production. The fibers of the invention have "cotton-like" properties but can be produced as continuous filaments on a year-round basis. The fibers are useful in textile applications.

The end face of an optical fiber 11 is polished at an angle to alter the cross-sectional dimensions of a light beam exiting the fiber through that end face to alter the cross-sectional circularity of the light beam after it has exited the fiber as compared to its cross-sectional circularity when it is in the fiber. For example, to increase the circularity of an exiting light beam, the angled fiber end face can be aligned such that the major axis of the sloping fiber end face is aligned with the ...

An optical fiber that contains a core of polycarbonate and a coating is disclosed. The coating is a polymer that contains structural units conforming to specified formulae. Also disclosed is a process for producing the inventive fibers and their use for transmitting optical signals.

Glass fibers are disclosed. The glass fibers can be used, for example, in a lead acid battery.

A cationic cellulosic fibre containing between 1 and 30 cationic groups and between 0.1 and 20 aldehyde groups per 100 anhydroglucose units is a suitable basis for producing paper and tissue products without the necessity of using non-biodegradable cationic polymers as wet strength additives. The cationic cellulosic fibre can be obtained by oxidation of the fibre to introduce aldehyde groups, followed by reaction of part of the aldehyde groups with a nitrogen-containing reagent such as betaine h...
