摘要： A method of separating carbon fiber tows. The method includes separating two or more first carbon fiber tows from a first tow band onto a second elevation to form two or more second carbon fiber tows from a second tow band. The two or more second carbon fiber tows from the second tow band leave gaps next to first adjacent tows of the two or more first carbon fiber tows remaining from the first tow band after the separating step. The first adjacent tows from the first tow band leave gaps next to second adjacent tows of the two or more second carbon fiber tows from the second tow band.

摘要： A fiber-based device having a reconfigurable geometry comprises an array of hair-like fibers spaced apart on a substrate, where each hair-like fiber comprises a free end extending away from the substrate and a secured end attached to the substrate. The array has a first bundled configuration where the free ends of the hair-like fibers are drawn together into a bundle having a first cross-sectional shape, and a second bundled configuration where the free ends of the hair-like fibers are drawn together into a bundle having a second cross-sectional shape. The array is reconfigurable from the first bundled configuration to the second bundled configuration by exposure to a liquid and then removal of the liquid at a predetermined rate.

In another embodiment, the fiber treatment system further includes an optionally rotatable spreader roller for flattening the fiber tow. In yet another embodiment, the loosened, but still continuous fiber tow is chopped by a downstream chopper to form short fibers with reduced tow sizes.

摘要： A nonwoven material has a plurality of randomly oriented and bulked crimped filaments, a plurality of point bonds interconnecting said crimped filaments into a fixed, 3-dimensional structure, and either a surface portion of said fixed, 3-dimensional structure having a greater density than an inner portion of said 3-dimensional structure or an external surface of said fixed, 3-dimensional structure being substantially free of any protruding filaments. The nonwoven material is made by: bulking a filament tow, fixing the bulked tow into a 3-dimensional structure, and calendering the 3-dimensional structure.

摘要： A composite yarn for technical or industrial use, particularly suitable for textile webs, is uniformly coated with a polymer and exhibits improved fir behavior and improved resistance to sheath stripping. The yarn may be obtained by a process where a continuous yarn, obtained by spinning a large number of fibers, such as about 100 to 600 fibers made of an organic or inorganic material, of a suitable yarn diameter, such as between about 1 to 10 micrometers, is subjected to a process for mechanically opening the yarn by splaying, to uniformly spread out and separate the fibers, including inner layers of the fibers, without impairing functional properties of the yarn, simultaneously with or prior to coating of the fibers by a polymer material having a viscosity between 1000 and 10,000 mPa·s, and formed to have a circular cross-section and uniformly distributed fibers throughout the cross-section of the polymer material to limit desheathing of the yarn.
